Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies:
	Principles of Consolidation
	The consolidated financial statements include the accounts of Lennox International Inc. and our majority-owned subsidiaries. All intercompany transactions, profits and balances have been eliminated.
	Cash and Cash Equivalents
	We consider all highly liquid temporary investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents consisted primarily of bank deposits.
	Accounts and Notes Receivable
	Accounts and notes receivable are shown in the accompanying Consolidated Balance Sheets, net of allowance for doubtful accounts. The allowance for doubtful accounts is generally established during the period in which receivables are recognized and is based on the age of the receivables and management's judgment on our ability to collect. Management considers the historical trends of write-offs and recoveries of previously written-off accounts, the financial strength of customers and projected economic and market conditions. We determine the delinquency status of receivables predominantly based on contractual terms and we write-off uncollectible receivables after management's review of our ability to collect, as noted above. We have no significant concentrations of credit risk within our accounts and notes receivable.
	Inventories
	Inventory costs include material, labor, depreciation and plant overhead. Inventories of $212.9 million and $187.3 million as of December 31, 2014 and 2013, respectively, were valued at the lower of cost or market using the last-in, first-out (“LIFO”) cost method. The remainder of inventory is valued at the lower of cost or market with cost determined primarily using either the first-in, first-out (“FIFO”) or average cost methods.
	We elected to use the LIFO cost method for our domestic manufacturing companies in 1974 and continued to elect the LIFO cost method for new operations through the late 1980s. The types of inventory costs that use LIFO include raw materials, purchased components, work-in-process, repair parts and finished goods. Since the late 1990s, we have adopted the FIFO cost method for all new domestic manufacturing operations (primarily acquisitions). Our operating entities with a previous LIFO election continue to use the LIFO cost method. We use the FIFO cost method for our foreign-based manufacturing facilities. See Note 3 for more information on our inventories.
	Property, Plant and Equipment
	Property, plant and equipment is stated at cost, net of accumulated depreciation. Expenditures that increase the utility or extend the useful lives of fixed assets are capitalized while expenditures for maintenance and repairs are charged to expense as incurred.
	Depreciation is computed using the straight-line method over the following estimated useful lives:
	Buildings and improvements:
	Buildings and improvements	5 to 30 years
	Leasehold improvements	1 to 20 years
	Machinery and equipment:
	Computer hardware	3 to 5 years
	Computer software	3 to 10 years
	Factory machinery and equipment	1 to 15 years
	Research and development equipment	5 to 10 years
	Vehicles	3 to 8 years
	We periodically review long-lived assets for impairment as events or changes in circumstances indicate that the carrying amount of such assets might not be recoverable. To assess recoverability, we compare the estimated expected future undiscounted cash flows identified with each long-lived asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being reviewed, an impairment loss is recognized based on the excess of the carrying amount of the impaired assets over their fair value. See Note 5 for additional information on our property, plant and equipment.
	Goodwill
	Goodwill represents the excess of cost over fair value of assets from acquired businesses. Goodwill is not amortized, but is reviewed for impairment annually and whenever events or changes in circumstances indicate the asset may be impaired.
	The annual goodwill impairment test was performed during the first quarter of 2014, and no impairment was recognized. During the third quarter of 2014, we changed the date of our annual goodwill impairment test from March 31st to December 31st. The change was made to more closely align the impairment testing date with the year-end results. The change in goodwill impairment testing date was deemed a change in accounting principle and did not delay, accelerate, or avoid a goodwill impairment charge. Management determined that the change in accounting principle was preferable under the circumstances and did not result in adjustments to our financial statements when applied retrospectively.
	The provisions of the accounting standard for goodwill allow us to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative goodwill impairment test. As part of our qualitative assessment, we monitor economic, legal, regulatory and other factors, industry trends, our market capitalization, recent and forecasted financial performance of our reporting units and the timing and nature of our restructuring activities for LII as a whole and for each reporting unit.
	For those reporting units which are evaluated using the two-step quantitative goodwill impairment test, we estimate reporting unit fair values using the discounted cash flow approach. The discounted cash flows used to estimate fair value are based on assumptions regarding each reporting unit’s estimated projected future cash flows and the estimated weighted-average cost of capital that a market participant would use in evaluating the reporting unit in a purchase transaction. The estimated weighted-average cost of capital is based on the risk-free interest rate and other factors such as equity risk premiums and the ratio of total debt to equity capital. In performing these impairment tests, we take steps to ensure that appropriate and reasonable cash flow projections and assumptions are used. We reconcile our estimated enterprise value to our market capitalization and determine the reasonableness of the cost of capital used by comparing to market data. We also perform sensitivity analyses on the key assumptions used, such as the weighted-average cost of capital and terminal growth rates. See Note 4 for additional information on our goodwill.
	Intangible Assets
	We amortize intangible assets and other assets with finite lives over their respective estimated useful lives to their estimated residual values, as follows:
	Asset	Useful Life
	Deferred financing costs	Effective interest method
	Customer relationships	Straight-line method up to 12 years
	Patents and others	Straight-line method up to 20 years
	We periodically review intangible assets with estimable useful lives for impairment as events or changes in circumstances indicate that the carrying amount of such assets might not be recoverable. We assess recoverability by comparing the estimated expected undiscounted future cash flows identified with each intangible asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being reviewed, an impairment loss is recognized based on the excess of the carrying amount of the impaired assets over their fair value. In assessing the fair value of these intangible assets, we must make assumptions that a market participant would make regarding estimated future cash flows and other factors to determine the fair value of the respective assets. If these estimates or the related assumptions change, we may be required to record impairment charges for these assets in the future.
	We review our indefinite-lived intangible assets for impairment annually in the fourth quarter and whenever events or changes in circumstances indicate the asset may be impaired. The provisions of the accounting standard for indefinite-lived intangible assets allow us to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative impairment test. As part of our qualitative assessment, we monitor economic, legal, regulatory and other factors, industry trends, recent and forecasted financial performance of our reporting units and the timing and nature of our restructuring activities for LII as a whole and as they relate to the fair value of the assets. For those intangible assets which are evaluated using the two-step quantitative impairment test, we compare the estimated expected undiscounted future cash flows identified with each intangible asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being reviewed, an impairment loss is recognized based on the excess of the carrying amount of the impaired assets over their fair value.
	Product Warranties
	For some of our heating, ventilation and air conditioning (“HVAC”) products, we provide warranty terms ranging from one to 20 years to customers for certain components such as compressors or heat exchangers. For select products, we also provide limited lifetime warranties. A liability for estimated warranty expense is recorded on the date that revenue is recognized. Our estimates of future warranty costs are determined by product line. The number of units we expect to repair or replace is determined by applying an estimated failure rate, which is generally based on historical experience, to the number of units that were sold and are still under warranty. The estimated units to be repaired under warranty are multiplied by the average cost to repair or replace such products to determine the estimated future warranty cost. We do not discount product warranty liabilities as the amounts are not fixed and the timing of future cash payments is neither fixed nor reliably determinable. We also provide for specifically-identified warranty obligations. Estimated future warranty costs are subject to adjustment depending on changes in actual failure rate and cost experience. Subsequent costs incurred for warranty claims serve to reduce the accrued product warranty liability. See Note 10 for more information on our estimated future warranty costs.
	Pensions and Post-retirement Benefits
	We provide pension and post-retirement medical benefits to eligible domestic and foreign employees and we recognize pension and post-retirement benefit costs over the estimated service life or average life expectancy of those employees. We also recognize the funded status of our benefit plans, as measured at year-end by the difference between plan assets at fair value and the benefit obligation, in the Consolidated Balance Sheets. Changes in the funded status are recognized in the year in which the changes occur through accumulated other comprehensive income (“AOCI”). Actuarial gains or losses are amortized into net period benefit cost over the estimated service life of covered employees or average life expectancy of participants depending on the plan.
	The benefit plan assets and liabilities reflect assumptions about the long-range performance of our benefit plans. Should actual results differ from management's estimates, revisions to the benefit plan assets and liabilities would be required. See Note 12 for information regarding those estimates and additional disclosures on pension and post-retirement medical benefits.
	Self-Insurance
	Self-insurance expense and liabilities were actuarially determined based primarily on our historical claims information and industry factors and trends. The self-insurance liabilities as of December 31, 2014 represent the best estimate of the future payments to be made on reported and unreported losses for 2014 and prior years. The amounts and timing of payments for claims reserved may vary depending on various factors, including the development and ultimate settlement of reported and unreported claims. To the extent actuarial assumptions change and claims experience rates differ from historical rates, our liabilities may change. See Note 10 for additional information on our self-insured risks and liabilities.
	Derivatives
	We use futures contracts and fixed forward contracts to mitigate our exposure to volatility in metal commodity prices and foreign exchange rates. We hedge only exposures in the ordinary course of business and do not hold or trade derivatives for profit. All derivatives are recognized in the Consolidated Balance Sheets at fair value and the classification of each derivative instrument is based upon whether the maturity of the instrument is less than or greater than 12 months. See Note 8 for more information on our derivatives.
	Income Taxes
	We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Unrecognized tax benefits are accounted for as required by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 740. See Note 9 for more information related to income taxes.
	Revenue Recognition
	Our revenue recognition practices for the sale of goods depend upon the shipping terms for each transaction. Shipping terms are primarily FOB Shipping Point and, therefore, revenue is recognized for these transactions when products are shipped to customers and title passes. Certain customers in our smaller operations, primarily outside of North America, have shipping terms where title and risk of ownership do not transfer until the product is delivered to the customer. For these transactions, revenue is recognized on the date that the product is received and accepted by such customers. We experience returns for miscellaneous reasons and record a reserve for these returns at the time we recognize revenue based on historical experience. Our historical rates of return are insignificant as a percentage of sales. We also recognize revenue net of sales taxes.
	For our businesses that provide services, revenue is recognized at the time services are completed. Our Commercial Heating & Cooling segment also provides sales, installation, maintenance and repair services under fixed-price contracts. Revenue for these services is recognized over the life of the contract.
	We engage in cooperative advertising, customer rebate, cash discount and other miscellaneous programs that result in payments or credits being issued to our customers. We record these customer discounts and incentives as a reduction of sales when the sales are recorded. For certain cooperative advertising programs, we also receive an identifiable benefit (goods or services) in exchange for the consideration given, and, accordingly, record a ratable portion of the expenditure to Selling, general and administrative (“SG&A”) expenses. All other advertising, promotions and marketing costs are expensed as incurred. See Note 23 for more information on these costs.
	Cost of Goods Sold
	The principal elements of cost of goods sold are components, raw materials, factory overhead, labor, estimated costs of warranty expense and freight and distribution costs.
	Selling, General and Administrative Expenses
	SG&A expenses include payroll and benefit costs, advertising, commissions, research and development, information technology costs, and other selling, general and administrative related costs such as insurance, travel, non-production depreciation and rent.
	Stock-Based Compensation
	We recognize compensation expense for stock-based arrangements over the required employee service periods. We measure stock-based compensation costs on the estimated grant-date fair value of the stock-based awards that are expected to ultimately vest and we adjust expected vesting rates to actual rates as additional information becomes known. For stock-based arrangements with performance conditions, we periodically adjust performance achievement rates based on our best estimates of those rates at the end of the performance period. See Note 14 for more information.
	Translation of Foreign Currencies
	All assets and liabilities of foreign subsidiaries and joint ventures are translated into U.S. dollars using rates of exchange in effect at the balance sheet date. Revenue and expenses are translated at weighted average exchange rates during the year. Unrealized translation gains and losses are included in AOCI in the accompanying Consolidated Balance Sheets. Transaction gains and losses are included in Losses and other expenses, net in the accompanying Consolidated Statements of Operations.
	Use of Estimates
	The preparation of financial statements requires us to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangible assets and other long-lived assets, contingencies, product warranties, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, pension and post-retirement medical benefits, and stock-based compensation among others. These estimates and assumptions are based on our best estimates and judgment.
	We evaluate these estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. We believe these estimates and assumptions to be reasonable under the circumstances and will adjust such estimates and assumptions when facts and circumstances dictate. Volatile equity, foreign currency and commodity markets and uncertain future economic conditions combine to increase the uncertainty inherent in such estimates and assumptions. Future events and their effects cannot be determined with precision and actual results could differ significantly from these estimates. Changes in these estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
	Reclassifications
	Certain amounts have been reclassified from the prior year presentation to conform to the current year presentation.

	(2) The goodwill balances in the table above are presented net of accumulated impairment charges of $15.7 million, all of which relate to impairments in periods prior to 2012.
	We reviewed our reporting unit structure as part of our annual goodwill impairment testing. We identified several components one level below our operating segments which were determined to be reporting units. We then performed our analysis to determine the proper aggregation of our reporting units, which considered similar economic and other characteristics, including product types, gross profits, production processes, customer types, distribution processes, and regulatory environments. Our analysis incorporated qualitative and quantitative measures to evaluate economic similarity and concluded that our reporting units continue to be equivalent to our operating segments.
	A qualitative review of impairment indicators was performed in 2014 for the Residential Heating & Cooling and the Commercial Heating & Cooling segments, and we determined that it was not more likely than not the fair values of our reporting units, individually or collectively, were less than their carrying values. Accordingly, a quantitative impairment analysis was not performed for these segments. Due to the softening of the North American supermarket and Australian wholesale businesses, a quantitative impairment analysis was performed for the Refrigeration segment using the discounted cash flow approach. The Refrigeration segment was not at risk of failing step one of the quantitative impairment test, and no impairments were recognized as part of the annual test. No other indicators of impairment were identified from the date of our annual impairment test through December 31, 2014. Also, we did not record any goodwill impairments related to continuing operations in 2012 or 2013. Refer to Note 17 for information on goodwill related to discontinued operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives:
	Objectives and Strategies for Using Derivative Instruments
	Commodity Price Risk. We utilize a cash flow hedging program to mitigate our exposure to volatility in the prices of metal commodities used in our production processes. Our hedging program includes the use of futures contracts to lock in prices, and as a result, we are subject to derivative losses should the metal commodity prices decrease and gains should the prices increase. We utilize a dollar cost averaging strategy so that a higher percentage of commodity price exposures are hedged near-term with lower percentages hedged at future dates. This strategy allows for protection against near-term price volatility while allowing us to adjust to market price movements over time.
	Interest Rate Risk. A portion of our debt bears interest at variable interest rates, and as a result, we are subject to variability in the cash paid for interest. To mitigate a portion of that risk, we may choose to engage in an interest rate swap hedging strategy to eliminate the variability of interest payment cash flows. Prior to 2013, we used an interest rate swap hedge to fix the interest payments associated with the first $100 million of the total variable-rate debt outstanding under our revolving credit facility tied to changes in the benchmark interest rate. The variable portion of the interest rate swap was tied to the 1-Month LIBOR (the benchmark interest rate). On a monthly basis, the interest rates for both the interest rate swap and the underlying debt were reset, the swap was settled with the counterparty, and the interest was paid. The interest rate swap was classified as a cash flow hedge and it expired on October 12, 2012. Subsequently, we have not hedged against interest rate risk.
	Foreign Currency Risk. Foreign currency exchange rate movements create a degree of risk by affecting the U.S. dollar value of assets and liabilities arising in foreign currencies. We seek to mitigate the impact of currency exchange rate movements on certain short-term transactions by periodically entering into foreign currency forward contracts. These forward contracts are not designated as hedges and generally expire during the quarter that we enter into them. By entering into forward contracts, we lock in exchange rates that would otherwise cause losses should the U.S. dollar appreciate and gains should the U.S. dollar depreciate.
	Cash Flow Hedges
	We have commodity futures contracts designated as cash flows hedges that are scheduled to mature through June 2016. Unrealized gains or losses from our cash flow hedges are included in accumulated other comprehensive income (“AOCI”) and are expected to be reclassified into earnings within the next 18 months based on the prices of the commodities at the settlement dates.
	We recorded the following amounts related to our cash flow hedges in AOCI (in millions):
		As of December 31,
		2014				2013
	Unrealized losses on unsettled contracts	$	7.2			$	0.8
	Income tax expense (benefit)	(2.6		)		(0.2		)
	Losses included in AOCI, net of tax (1)	$	4.6			$	0.6
	(1) Assuming commodity prices remain constant, we expect to reclassify $4.2 million of derivative losses into earnings within the next 12 months.

	Deferred income taxes reflect the tax consequences on future years of temporary differences between the tax basis of assets and liabilities and their financial reporting basis and are reflected as current or non-current depending on the classification of the asset or liability generating the deferred tax. The deferred tax provision for the periods shown represents the effect of changes in the amounts of temporary differences during those periods.
	Deferred tax assets (liabilities) were comprised of the following (in millions):

	Net deferred tax assets	$	129.9		$	113
	As of December 31, 2014 and 2013, we had $3.8 million and $5.0 million in tax-effected state net operating loss carryforwards, respectively, and $18.5 million and $21.8 million in tax-effected foreign net operating loss carryforwards, respectively. The state and foreign net operating loss carryforwards began expiring in 2014. The deferred tax asset valuation allowance relates primarily to the operating loss carryforwards in various states in the U.S., European and Asian tax jurisdictions. The remainder of the valuation allowance relates to state tax credits which began to expire in 2014.
	In assessing whether a deferred tax asset will be realized, we consider whether it is more likely than not that some portion or all of the deferred tax asset will not be realized. We consider the reversal of existing taxable temporary differences, projected future taxable income and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, we believe it is more likely than not we will realize the benefits of these deductible differences, net of the existing valuation allowances, as of December 31, 2014.
	To realize the net deferred tax asset, we will need to generate future foreign taxable income of approximately $71.2 million during the periods in which those temporary differences become deductible. We do not need to generate additional U.S. federal income as we have sufficient carryback capacity to fully realize the federal deferred tax asset. U.S. taxable income for the years ended December 31, 2014 and 2013 was $201.6 million and $198.7 million, respectively.
	No provision was made for income taxes which may become payable upon distribution of our foreign subsidiaries' earnings. These earnings were approximately $122.2 million as of December 31, 2014. It is not practicable to estimate the amount of tax that might be payable because our intent is to permanently reinvest these earnings or to repatriate earnings when it is tax effective to do so.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions):
Balance as of December 31, 2012	$	1
Increases related to prior year tax positions	0.7
Decreases related to prior year tax positions	(0.1		)
Increases related to current year tax positions	0.1
Balance as of December 31, 2013	1.7

Decreases related to prior year tax positions	(0.7		)
Increases related to current year tax positions	—
Settlement	$	(0.1	)
Balance as of December 31, 2014	$	1.6
Included in the balance of unrecognized tax benefits as of December 31, 2014 are potential benefits of $1.2 million that, if recognized, would affect the effective tax rate on income from continuing operations. As of December 31, 2014, we recognized $0.2 million (net of federal tax benefits) in interest and penalties in income tax expense.
We are currently under examination for our U.S. federal income taxes for 2014 and 2013 and are subject to examination by numerous other taxing authorities in the U.S. and in jurisdictions such as Australia, Belgium, France, Canada, and Germany. We are generally no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by taxing authorities for years before 2009.
Since January 1, 2013, numerous states, including New Mexico, North Carolina, North Dakota, Minnesota, Oregon, Texas and West Virginia enacted legislation effective for tax years beginning on or after January 1, 2013, including changes to rates and apportionment methods. The impact of these changes is immaterial.

	On March 22, 2013, we entered into an agreement with a financial institution to renew the lease of our corporate headquarters in Richardson, Texas for a term of approximately six years through March 1, 2019 (the “Lake Park Renewal”). The leased property consists of an office building of approximately 192,000 square feet, land and related improvements. During the lease term, the Lake Park Renewal requires us to pay base rent in quarterly installments, payable in arrears. At the end of the lease term, we must do one of the following: (i) purchase the property for $41.2 million; (ii) vacate the property and return it in good condition; (iii) arrange for the sale of the leased property to a third party; or (iv) renew the lease under mutually agreeable terms. If we elect to sell the property to a third party and the sales proceeds are less than the lease balance, we must pay any such deficit to the financial institution. Any such deficit payment cannot exceed 86% of the lease balance. The Lake Park Renewal is classified as an operating lease and its future annual minimum lease payments are included in the table above.
	Our obligations under the Lake Park Lease are secured by a pledge of our interest in the leased property. The Lake Park Renewal contains customary lease covenants and events of default as well as events of default if (i) indebtedness of $75 million or more is not paid when due, (ii) there is a change of control or (iii) we fail to comply with certain covenants incorporated from our Fifth Amended and Restated Credit Facility Agreement. We were in compliance with these financial covenants as of December 31, 2014.
	Environmental
	Environmental laws and regulations in the locations we operate can potentially impose obligations to remediate hazardous substances at our properties, properties formerly owned or operated by us, and facilities to which we have sent or send waste for treatment or disposal. We are aware of contamination at some facilities, however, we do not believe that any future remediation related to those facilities will be material to our results of operations. Total environmental accruals are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):
		As of December 31,
		2014			2013
	Accrued expenses	$	1.7		$	1.4
	Other liabilities	4.5			3.8
	Total environmental accruals	$	6.2		$	5.2
	Future environmental costs are estimates and may be subject to change due to changes in environmental remediation regulations, technology or site-specific requirements.
	Product Warranties and Product Related Contingencies
	We incur the risk of liability for claims related to the installation and service of heating and air conditioning products, and we maintain liabilities for those claims that we self-insure. We are involved in various claims and lawsuits related to our products. Our product liability insurance policies have limits that, if exceeded, may result in substantial costs that could have an adverse effect on our results of operations. In addition, warranty claims and certain product liability claims are not covered by our product liability insurance.
	Total product warranty liabilities related to continuing operations are included in the following captions on the accompanying Consolidated Balance Sheets (in millions):
		As of December 31,
		2014			2013
	Accrued expenses	$	27.3		$	28.7
	Other liabilities	59.9			52.9
	Total product warranty liabilities	$	87.2		$	81.6
	The changes in product warranty liabilities related to continuing operations for the years ended December 31, 2014 and 2013 were as follows (in millions):
	Total warranty liability as of December 31, 2012	$	71.9
	Payments made in 2013	(21.3		)
	Changes resulting from issuance of new warranties	29.6
	Changes in estimates associated with pre-existing liabilities	1.6

	Changes resulting from issuance of new warranties	33.4
	Changes in estimates associated with pre-existing liabilities	(3.5		)
	Changes in foreign currency translation rates and other	(1.2		)
	Total warranty liability as of December 31, 2014	$	87.2
	We have incurred, and will likely continue to incur, product costs not covered by insurance or our suppliers’ warranties.   Also, to satisfy our customers and protect our brands,  we have repaired or replaced installed products experiencing quality-related issues, and will likely continue such repairs and replacements.   We currently estimate our probable liability for a supplier quality issue within a range of $2.2 million and $6 million; accordingly, we accrued, as of December 31, 2014, a $2.2 million liability in Accrued Expenses on the Consolidated Balance Sheet because all amounts in that range were equally likely. The supplier has agreed to reimburse our costs related to this liability; accordingly, we also recorded, as of December 31, 2014, a receivable of $2.2 million in Other Assets on the Consolidated Balance Sheet.  If additional costs are incurred, we expect the supplier will also reimburse those costs. The $2.2 million accrual is not included in the estimated warranty liabilities tables immediately above.
	Self Insurance
	We use a combination of third-party insurance and self-insurance plans to provide protection against claims relating to workers' compensation/employers' liability, general liability, product liability, auto liability, auto physical damage and other exposures. We use large deductible insurance plans, written through third-party insurance providers, for workers' compensation/employers' liability, general liability, product liability and auto liability. We also carry umbrella or excess liability insurance for all third-party and self-insurance plans, except for directors' and officers' liability, property damage and certain other insurance programs. For directors' and officers' liability, property damage and certain other exposures, we use third-party insurance plans that may include per occurrence and annual aggregate limits. We believe the deductibles and liability limits for all of our insurance policies are appropriate for our business and are adequate for companies of our size in our industry.
	We maintain safety and manufacturing programs that are designed to remove risk, improve the effectiveness of our business processes and reduce the likelihood and significance of our various retained and insured risks. In recent years, our actual claims experience has collectively trended favorably and, as a result, both self-insurance expense and the related liability have decreased.
	Total self-insurance liabilities were included in the following captions on the accompanying Consolidated Balance Sheets (in millions):
		As of December 31,
		2014			2013
	Accrued expenses	$	13		$	13.4
	Other liabilities	25.8			32
	Total self-insurance liabilities	$	38.8		$	45.4
	Litigation
	We are involved in a number of claims and lawsuits incident to the operation of our businesses. Insurance coverages are maintained and estimated costs are recorded for such claims and lawsuits, including costs to settle claims and lawsuits, based on experience involving similar matters and specific facts known.
	Some of these claims and lawsuits allege personal injury or health problems resulting from exposure to asbestos that was integrated into certain of our products. We have never manufactured asbestos and have not incorporated asbestos-containing components into our products for several decades. A substantial majority of asbestos-related claims have been covered by insurance or other forms of indemnity or have been dismissed without payment. The remainder of our closed cases have been resolved for amounts that are not material, individually or in the aggregate. Our defense costs for asbestos-related claims are generally covered by insurance; however, our insurance coverage for settlements and judgments for asbestos-related claims vary depending on several factors, and are subject to policy limits, so we may have greater financial exposure for future settlements and judgments. For the years ended December 31, 2014 and 2013, we recorded expense of $0.9 million and $6.3 million, respectively, net of probable insurance recoveries, for known and future asbestos-related litigation.
	We are the defendant in an attempted class action lawsuit which alleges that evaporator coils in our residential air conditioning products are susceptible to a type of corrosion that can result in coil leaks, and asserts claims for relief.  We dispute the allegations in the lawsuit.  The outcome related to this action is uncertain but we do not expect this lawsuit to have a material adverse effect on our financial condition or results of operations.
	It is management's opinion that none of these claims or lawsuits or any threatened litigation will have a material adverse effect on our financial condition, results of operations or cash flows. Claims and lawsuits, however, involve uncertainties and it is possible that their eventual outcome could adversely affect our results of operations in a future period.

	Short-Term Debt
	Short Term Facility
	On October 20, 2014, Lennox International Inc. (the “Company”) entered into a short term loan agreement (the “Short-Term Facility”) with JPMorgan Chase Bank, N.A., as administrative agent, and Morgan Stanley Bank, N.A. and the other lenders named therein, to borrow $250.0 million. The Short-Term Facility had a maturity date of March 31, 2015, but was prepaid in full without penalty in November 2014. The term loan bore interest at a variable base rate or a variable rate based on the London interbank offered rate, at the Company’s election, plus a spread.
	Foreign Obligations
	Through several of our foreign subsidiaries, we have available to us facilities to assist in financing seasonal borrowing needs for our foreign locations. We had $6.6 million and $5.9 million of foreign obligations as of December 31, 2014 and 2013, respectively, that were primarily borrowings under non-committed facilities. Proceeds on these facilities were $18.1 million, $18.3 million and $18.5 million during the years ended December 31, 2014, 2013 and 2012, respectively. Repayments on the facilities were $16.6 million, $16.3 million and $18.3 million during the years ended December 31, 2014, 2013 and 2012, respectively.
	Asset Securitization Program
	Under the Asset Securitization Program (“ASP”), we are eligible to sell beneficial interests in a portion of our trade accounts receivable to participating financial institutions for cash. The ASP is subject to annual renewal and contains a provision whereby we retain the right to repurchase all of the outstanding beneficial interests transferred. Our continued involvement with the transferred assets includes servicing, collection and administration of the transferred beneficial interests. The accounts receivable securitized under the ASP are high-quality domestic customer accounts that have not aged significantly. The receivables represented by the retained interest that we service are exposed to the risk of loss for any uncollectible amounts in the pool of receivables sold under the ASP. The fair values assigned to the retained and transferred interests are based on the sold accounts receivable carrying value given the short term to maturity and low credit risk. The sale of the beneficial interests in our trade accounts receivable are reflected as secured borrowings in the accompanying Consolidated Balance Sheets and proceeds received are included in cash flows from financing activities in the accompanying Consolidated Statements of Cash Flows.
	In November 2014, we amended the ASP, extending its term to November 13, 2015 and increasing the maximum securitization amount from a range of $160.0 million to $220.0 million to a range of $180.0 million to $220.0 million, depending on the period. The maximum capacity under the ASP is the lesser of the maximum securitization amount or 100% of the net pool balance less reserves, as defined by the ASP. Eligibility for securitization is limited based on the amount and quality of the qualifying accounts receivable and is calculated monthly. The eligible amounts available and beneficial interests sold were as follows (in millions):
		As of December 31,
		2014			2013
	Eligible amount available under the ASP on qualified accounts receivable	$	220		$	160
	Beneficial interest sold	220			160
	Remaining amount available	$	—		$	—
	We pay certain discount fees to use the ASP and to have the facility available to us. These fees relate to both the used and unused portions of the securitization. The used fee is based on the beneficial interest sold and calculated on either the average LIBOR rate or floating commercial paper rate determined by the purchaser of the beneficial interest, plus a program fee of 0.60%. The average rates as of December 31, 2014 and 2013 were 0.79% and 0.78%, respectively. The unused fee is based on 101% of the maximum available amount less the beneficial interest sold and calculated at a 0.30% fixed rate throughout the term of the agreement. In addition, a 0.05% unused fee is charged on incremental available amounts above $180.0 million during certain months of the year. We recorded these fees in Interest expense, net in the accompanying Consolidated Statements of Operations.
	The ASP contains certain restrictive covenants relating to the quality of our accounts receivable and cross-default provisions with our Fifth Amended and Restated Credit Facility Agreement ("Domestic Credit Facility"), senior unsecured notes and any other indebtedness we may have over $75.0 million. The administrative agent under the ASP is also a participant in our Domestic Credit Facility. The participating financial institutions have investment grade credit ratings. We continue to evaluate their credit ratings and have no reason to believe they will not perform under the ASP. As of December 31, 2014, we were in compliance with all covenant requirements.
	Long-Term Debt
	Domestic Credit Facility
	On November 13, 2014, we replaced our $650 million Domestic Revolving Credit Facility with a $950 million Domestic Credit Facility, which consists of a $650 million revolving credit facility and a $300 million term loan and matures in November 2019. Under our $950 million Domestic Credit Facility, we had outstanding borrowings of $482.0 million as well as 27.2 million committed to standby letters of credit as of December 31, 2014. Subject to covenant limitations, $440.8 million was available for future borrowings. The unsecured $300 million term loan also matures on the Maturity Date and requires quarterly principal repayments of $7.5 million beginning on June 30, 2015. The revolving credit facility allows up to $150 million of letters of credit to be issued and also includes a subfacility for swingline loans of up to $65 million. Additionally, at our request and subject to certain conditions, the commitments under the Domestic Credit Facility may be increased by a maximum of $350 million as long as existing or new lenders agree to provide such additional commitments.
	Our weighted average borrowing rate on the facility was as follows:
		As of December 31,
		2014		2013
	Weighted average borrowing rate	1.88	%	1.17	%
	Our Domestic Credit Facility is guaranteed by certain of our subsidiaries and contains financial covenants relating to leverage and interest coverage. Other covenants contained in the Domestic Credit Facility restrict, among other things, certain mergers, asset dispositions, guarantees, debt, liens, and affiliate transactions. The financial covenants require us to maintain a defined Consolidated Indebtedness to Adjusted EBITDA Ratio and a Cash Flow (defined as EBITDA minus capital expenditures) to Net Interest Expense Ratio. The required ratios under our Domestic Credit Facility are detailed below:
	Consolidated Indebtedness to Adjusted EBITDA Ratio no greater than	3.5 : 1.0
	Cash Flow to Net Interest Expense Ratio no less than	3.0 : 1.0
	Our Domestic Credit Facility contains customary events of default. These events of default include nonpayment of principal or interest, breach of covenants or other restrictions or requirements, default on certain other indebtedness or receivables securitizations (cross default), and bankruptcy. A cross default under our Domestic Credit Facility could occur if:
	•	We fail to pay any principal or interest when due on any other indebtedness or receivables securitization of at least $75.0 million; or
	•	We are in default in the performance of, or compliance with any term of any other indebtedness or receivables securitization in an aggregate principal amount of at least $75.0 million or any other condition exists which would give the holders the right to declare such indebtedness due and payable prior to its stated maturity.
	Each of our major debt agreements contains provisions by which a default under one agreement causes a default in the others (a cross default). If a cross default under the Domestic Credit Facility, our senior unsecured notes, the Lake Park Renewal or our ASP were to occur, it could have a wider impact on our liquidity than might otherwise occur from a default of a single debt instrument or lease commitment.
	If any event of default occurs and is continuing, lenders with a majority of the aggregate commitments may require the administrative agent to terminate our right to borrow under our Domestic Credit Facility and accelerate amounts due under our Domestic Credit Facility (except for a bankruptcy event of default, in which case such amounts will automatically become due and payable and the lenders’ commitments will automatically terminate). As of December 31, 2014, we were in compliance with all covenant requirements.
	Senior Unsecured Notes
	We issued $200.0 million of senior unsecured notes in May 2010 through a public offering. Interest is paid semiannually on May 15 and November 15 at a fixed interest rate of 4.90% per annum. These notes mature on May 15, 2017. The notes are guaranteed, on a senior unsecured basis, by each of our domestic subsidiaries that guarantee payment by us of any indebtedness under our Domestic Credit Facility. The indenture governing the notes contains covenants that, among other things, limit our ability and the ability of the subsidiary guarantors to: create or incur certain liens; enter into certain sale and leaseback transactions; enter into certain mergers, consolidations and transfers of substantially all of our assets; and transfer certain properties. The indenture also contains a cross default provision which is triggered if we default on other debt of at least $75 million in principal which is then accelerated, and such acceleration is not rescinded within 30 days of the notice date. As of December 31, 2014, we were in compliance with all covenant requirements.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans:
	Over the past several years, we have frozen many of our defined benefit pension and profit sharing plans and replaced them with defined contribution plans. We have a liability for the benefits earned under these inactive plans prior to the date the benefits were frozen. Our defined contribution plans generally include both company and employee contributions which are based on predetermined percentages of compensation earned by the employee. We also have several active defined benefit plans that provide benefits based on years of service.
	In addition to freezing the benefits of our defined benefit pension plans, we have also eliminated nearly all of our post-retirement medical benefits. In 2012, we amended the post-retirement benefit plan to shift pre-65 medical coverage for the employees of our largest manufacturing plant so that by 2015, retirees would pay 100% of the cost of post-retirement medical coverage. This change resulted in a significant reduction in the projected benefit obligation for post-retirement medical benefits in 2012.

The following tables set forth the weighted-average assumptions used to determine Benefit Obligations and Net Periodic Benefit Cost for the non-U.S.-based plans in 2014 and 2013:
	Pension Benefits
	2014			2013
Weighted-average assumptions used to determine benefit obligations as of December 31:
Discount rate	3.45	%		4.38	%
Rate of compensation increase	3.66	%		3.31	%
	Pension Benefits
	2014			2013			2012
Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31:
Discount rate	4.38	%		4.12	%		4.93	%
Expected long-term return on plan assets	6.32	%		6.05	%		6.26	%
Rate of compensation increase	3.31	%		3.48	%		3.68	%
To develop the expected long-term rate of return on assets assumption for the U.S. plans, we considered the historical returns and the future expectations for returns for each asset category, as well as the target asset allocation of the pension portfolio and the effect of periodic balancing. These results were adjusted for the payment of reasonable expenses of the plan from plan assets. This resulted in the selection of the 8.0% long-term rate of return on assets assumption. A similar process was followed for the non-U.S.-based plans.
To select a discount rate for the purpose of valuing the plan obligations for the U.S. plans, we performed an analysis in which the duration of projected cash flows from defined benefit and retiree healthcare plans was matched with a yield curve based on the appropriate universe of high-quality corporate bonds that were available. We used the results of the yield curve analysis to select the discount rate that matched the duration and payment stream of the benefits in each plan. This resulted in the selection of the 4.94% discount rate assumption for the U.S. qualified pension plans, 4.30% for the U.S. non-qualified pension plans, and 3.23% for the other benefits. A similar process was followed for the non-U.S.-based plans.
Assumed health care cost trend rates have an effect on the amounts reported for our healthcare plan. The following table sets forth the healthcare trend rate assumptions used:
	2014			2013
Assumed health care cost trend rates as of December 31:

Pension Plan Assets
We believe asset returns can be optimized at an acceptable level of risk by adequately diversifying the plan assets between equity and fixed income. In the first quarter of 2014, in order to increase diversification, we changed the targeted allocations for our plan assets. The target allocations for fixed income, money market, cash and guaranteed investment contracts investments increased from 40% to 58% while targeted equity investment allocations declined from 60% to 42%. We decreased our exposure to International equity from 24% to 17% of total assets and reduced our exposure to domestic equity from 36% to 25%. These categories are further diversified among various asset classes including high yield and emerging markets debt, and international and emerging markets equities in order to avoid significant concentrations of risk. Our U.S. pension plan represents 88%, our Canadian pension plan 6%, and our United Kingdom (“U.K.”) pension plan 6% of the total fair value of our plan assets as of December 31, 2014.
Our U.S. pension plans' weighted-average asset allocations as of December 31, 2014 and 2013, by asset category, are as follows:
	Plan Assets as of December 31,
Asset Category:	2014			2013
U.S. equity	28.3	%		37.8	%
International equity	17.1	%		26.7	%
Fixed income	52.6	%		33.8	%
Money market/cash	2	%		1.7	%
Total	100	%		100	%
U.S. pension plan assets are invested within the following range targets:
Asset Category:	Target
U.S. equity	25	%
International equity	17	%
Fixed income	56	%
Money market/cash/guaranteed investment contracts	2	%
Our Canadian pension plan was invested solely in a balanced fund that maintains diversification among various asset classes, including Canadian common stocks, bonds and money market securities, international equities and fixed income investments. Our U.K. pension plan was invested in a broad mix of assets consisting of U.K., international equities, and U.K. fixed income securities, including corporate and government bonds.

The majority of our commingled pool/collective trusts, mutual funds, balanced pension trusts and pension funds are managed by professional investment advisors. The NAVs per share are furnished in monthly and/or quarterly statements received from the investment advisors and reflect valuations based upon their pricing policies. We assessed the fair value classification of these investments as Level 2 for commingled pool/collective trusts, balanced pension trusts and pension funds based on an examination of their pricing policies and the related controls and procedures. The fair values we report are based on the pool, trust or fund's NAV per share. The NAVs per share are calculated periodically (daily or no less than one time per month) as the aggregate value of each pool or trust's underlying assets divided by the number of units owned. See Note 20 for information about our fair value hierarchies and valuation techniques.

	Stock-Based compensation expense related to continuing operations was included in Selling, general and administrative expenses in the accompanying Consolidated Statements of Operations as follows (in millions):
		For the Years Ended December 31,
		2014				2013				2012
	Compensation expense(1)	$	23.3			$	29.3			$	15.2
	(1) Stock-Based compensation expense was recorded in our Corporate and other business segment.
	Incentive Plan
	Under the Lennox International Inc. 2010 Incentive Plan, as amended and restated (the “2010 Incentive Plan”), we are authorized to issue awards for 24.3 million shares of common stock. The 2010 Incentive Plan provides for various long-term incentive awards, including performance share units, restricted stock units and stock appreciation rights. A description of these long-term incentive awards and related activity within each award category is provided below.
	As of December 31, 2014, awards for 20.5 million shares of common stock had been granted, net of cancellations and repurchases, and there were 3.8 million shares available for future issuance.
	Performance Share Units
	Performance share units are granted to certain employees at the discretion of the Board of Directors with a three-year performance period beginning January 1st of each year. Upon meeting the performance and vesting criteria, performance share units are converted to an equal number of shares of our common stock. Performance share units vest if, at the end of the three-year performance period, at least the threshold performance level has been attained. To the extent that the payout level attained is less than 100%, the difference between 100% and the units earned and distributed will be forfeited. Eligible participants may also earn additional units of our common stock, which would increase the potential payout up to 200% of the units granted, depending on LII's performance over the three-year performance period.
	Performance share units are classified as equity awards. Compensation expense is recognized ratably over the service period and is based on the expected number of units to be earned and the fair value of the stock at the date of grant. The fair value of units is calculated as the average of the high and low market price of the stock on the date of grant discounted by the expected dividend rate over the service period. The number of units expected to be earned will be adjusted in future periods as necessary to reflect changes in the estimated number of award to be issued and, upon vesting, the actual number of units awarded. Our practice is to issue new shares of common stock or utilize treasury stock to satisfy performance share unit distributions.
	The following table provides information on our performance share units:
		For the Years Ended December 31,
		2014				2013				2012
	Compensation expense for performance share units (in millions)	$	11.5			$	17.1			$	5.7

	Undistributed performance share units as of December 31, 2014 (1)	0.8			$	49.47
	(1) Undistributed performance share units include approximately 0.4 million units with a weighted-average grant date fair value of $68.27 per share that had not yet vested and 0.4 million units that have vested but were not yet distributed.
	As of December 31, 2014, we had $15.9 million of total unrecognized compensation cost related to non-vested performance share units that is expected to be recognized over a weighted-average period of 2.2 years. Our estimated forfeiture rate for these performance share units was 16.5% as of December 31, 2014.
	The total fair value of performance share units distributed and the resulting tax deductions to realize tax benefits were as follows (in millions):
		For the Years Ended December 31,
		2014				2013				2012
	Fair value of performance share units distributed	$	19.6			$	9.9			$	6
	Realized tax benefits from tax deductions	$	7.5			$	3.8			$	2.3
	Restricted Stock Units
	Restricted stock units are issued to attract and retain key employees. Generally, at the end of a three-year retention period, the units will vest and be distributed in shares of our common stock to the participant. Our practice is to issue new shares of common stock or utilize treasury stock to satisfy restricted stock unit vestings. Restricted stock units are classified as equity awards. The fair value of units granted is the average of the high and low market price of the stock on the date of grant discounted by the expected dividend rate over the service period. Units are amortized to compensation expense ratably over the service period.
	The following table provides information on our restricted stock units (in millions, except per share data):
		For the Years Ended December 31,
		2014				2013				2012
	Compensation expense for restricted stock units	$	7			$	6.8			$	5
	Weighted-average fair value of grants, per share	$	88.26			$	77.26			$	48.45

	Forfeited	—			—
	Non-vested restricted stock units as of December 31, 2014	0.4			$	69.09
	As of December 31, 2014, we had $14.9 million of total unrecognized compensation cost related to non-vested restricted stock units that is expected to be recognized over a weighted-average period of 2.4 years. Our estimated forfeiture rate for restricted stock units was 16.9% as of December 31, 2014.
	The total fair value of restricted stock units vested and the resulting tax deductions to realize tax benefits were as follows (in millions):
		For the Years Ended December 31,
		2014				2013				2012
	Fair value of restricted stock units vested	$	19.5			$	11.1			$	8.6
	Realized tax benefits from tax deductions	7.4				4.3				3.3
	Stock Appreciation Rights
	Stock appreciation rights are issued to certain key employees. Each recipient is given the “right” to receive a value, paid in shares of our common stock, equal to the future appreciation of our common stock price. Stock appreciation rights generally vest in one-third increments beginning on the first anniversary date after the grant date and expire after seven years. Our practice is to issue new shares of common stock or utilize treasury stock to satisfy the exercise of stock appreciation rights.
	The following table provides information on our stock appreciation rights (in millions, except per share data):
		For the Years Ended December 31,
		2014				2013				2012
	Compensation expense for stock appreciation rights	$	4.8			$	5.4			$	4.5
	Weighted-average fair value of grants, per share	19.55				18.76				14.34
	Compensation expense for stock appreciation rights is based on the fair value on the date of grant, estimated using the Black-Scholes-Merton valuation model, and is recognized over the service period. We used historical stock price data to estimate the expected volatility. We determined that the recipients of stock appreciation rights can be combined into one employee group that has similar historical exercise behavior and we used our historical pattern of award exercises to estimate the expected life of the awards for the employee group. The risk-free interest rate was based on the zero-coupon U.S. Treasury yield curve with a maturity equal to the expected life of the awards at the time of grant.
	The fair value of the stock appreciation rights granted in 2014, 2013 and 2012 were estimated on the date of grant using the following assumptions:
		2014			2013			2012
	Expected dividend yield	1.75	%		1.36	%		1.75	%
Risk-free interest rate	1.27	%		1.12	%		0.48	%
Expected volatility	29.6	%		31.5	%		40.42	%
Expected life (in years)	4.04			4.02			4.14
A summary of our stock appreciation rights as of December 31, 2014, and changes during the year then ended, is presented below (in millions, except per share data):
	Shares			Weighted-Average Exercise Price per Share
Outstanding stock appreciation rights as of December 31, 2013	1.8			$	45.58

Employee Stock Purchase Plan
Under the 2012 Employee Stock Purchase Plan (“ESPP”), all employees who meet certain service requirements are eligible to purchase our common stock through payroll deductions at the end of three month offering periods. The purchase price for such shares is 95% of the fair market value of the stock on the last day of the offering period. A maximum of 2.5 million shares is authorized for purchase until the ESPP plan termination date of May 10, 2022, unless terminated earlier at the discretion of the Board of Directors. Employees purchased approximately 20,000 shares under the ESPP during the year ended December 31, 2014. Approximately 2.4 million shares remain available for purchase under the ESPP as of December 31, 2014.

Stockholders' Equity Note [Abstract]
Stock Repurchases	Stock Repurchases:
	Our Board of Directors has authorized a total of $1.4 billion towards the repurchase of shares of our common stock (collectively referred to as the "Share Repurchase Plans"), including a $700.0 million share repurchase authorization in October 2014. The Share Repurchase Plans authorize open market repurchase transactions and do not have a stated expiration date. As of December 31, 2014, $395.9 million of shares may still be repurchased under the Share Repurchase Plans.
	On October 20, 2014, we announced our plans for a new $450.0 million accelerated share repurchase program. For the years ended December 31, 2014 and 2013, we repurchased 5.2 million shares for $550.3 million and 1.7 million shares for $125.0 million, respectively, under the Share Repurchase Plans. The final number of shares to be repurchased and the aggregate cost to LII will be based on LII's volume-weighted average stock price during the term of the transaction, which is expected to be completed in the second half of 2015.
	We also repurchased 0.2 million shares for $22.4 million and 0.2 million shares for $12.0 million for the years ended December 31, 2014 and 2013, respectively, from employees who surrendered their shares to satisfy minimum tax withholding obligations upon the vesting of stock-based compensation awards.

Restructuring Charges [Abstract]
Restructuring Charges	Restructuring Charges:
	We record restructuring charges associated with management-approved restructuring plans to reorganize or to remove duplicative headcount and infrastructure within our businesses. Restructuring charges include severance costs to eliminate a specified number of employees, infrastructure charges to vacate facilities and consolidate operations, contract cancellation costs and other related activities. The timing of associated cash payments is dependent upon the type of restructuring charge and can extend over a multi-year period. Restructuring charges are not included in our calculation of segment profit (loss), as more fully explained in Note 19.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share:
	Basic earnings per share are computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share are computed by dividing net income by the sum of the weighted-average number of shares and the number of equivalent shares assumed outstanding, if dilutive, under our stock-based compensation plans.
	The computations of basic and diluted earnings per share for Income from continuing operations were as follows (in millions, except per share data):
		For the Years Ended December 31,
		2014				2013			2012
	Net income	$	205.8			$	171.8		$	90

Segment Reporting, Measurement Disclosures [Abstract]
Reportable Business Segments	Reportable Business Segments:
	Description of Segments
	We operate in three reportable business segments of the heating, ventilation, air conditioning and refrigeration (“HVACR”) industry. Our segments are organized primarily by the nature of the products and services we provide. The following table describes each segment:
	Segment		Products or Services		Markets Served		Geographic Areas
	Residential Heating & Cooling		Furnaces, air conditioners, heat pumps, packaged heating and cooling systems, indoor air quality equipment, comfort control products, replacement parts		Residential Replacement;		United States
					Residential New Construction		Canada
	Commercial Heating & Cooling		Unitary heating and air conditioning equipment, applied systems, controls, installation and service of commercial heating and cooling equipment		Light Commercial		United States
							Canada
							Europe
	Refrigeration		Condensing units, unit coolers, fluid coolers, air cooled condensers, air handlers, process chillers, controls, compressorized racks, supermarket display cases and systems		Light Commercial;		United States
					Food Preservation;		Canada
					Non-Food/Industrial		Europe
							Asia Pacific
							South America
	In September 2012, we announced the planned sale of our Service Experts business. The Service Experts business had previously been reported within the Service Experts reportable segment along with the Lennox National Account Services ("NAS") business. Beginning in the third quarter of 2012, the Service Experts business was included in discontinued operations, NAS was included in our Commercial Heating & Cooling segment, and the Service Experts segment was eliminated. Results for all periods have been revised to reflect this new presentation.
	Segment Data
	We use segment profit or loss as the primary measure of profitability to evaluate operating performance and to allocate capital resources. We define segment profit or loss as a segment’s income or loss from continuing operations before income taxes included in the accompanying Consolidated Statements of Operations, excluding certain items. The reconciliation below details the items excluded.
	Our corporate costs include those costs related to corporate functions such as legal, internal audit, treasury, human resources, tax compliance and senior executive staff. Corporate costs also include the long-term share-based incentive awards provided to employees throughout LII. We recorded these share-based awards as Corporate costs because they are determined at the discretion of the Board of Directors and based on the historical practice of doing so for internal reporting purposes.
	As they arise, transactions between segments are recorded on an arm’s-length basis using the relevant market prices. Any intercompany sales and associated profit (and any other intercompany items) are eliminated from segment results. There were no significant intercompany eliminations included in the results presented in the table below.
	Net sales and segment profit (loss) by segment, along with a reconciliation of segment profit (loss) to Income from continuing operations before income taxes, are shown below (in millions):

Fair_Value_Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements:
	Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date and requires consideration of our creditworthiness when valuing certain liabilities. Our framework for measuring fair value is based on the following three-level hierarchy for fair value measurements:
	Level 1 -     Quoted prices for identical instruments in active markets at the measurement date.
	Level 2 -	Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets at the measurement date and for the anticipated term of the instrument.
	Level 3 -	Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable inputs that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.
	Where available, the fair values were based upon quoted prices in active markets. However, if quoted prices were not available, then the fair values were based upon quoted prices for similar assets or liabilities or independently sourced market parameters, such as credit default swap spreads, yield curves, reported trades, broker/dealer quotes, interest rates and benchmark securities. For assets and liabilities without observable market activity, if any, the fair values were based upon discounted cash flow methodologies incorporating assumptions that, in our judgment, reflect the assumptions a marketplace participant would use. Valuation adjustments to reflect either party's creditworthiness and ability to pay were incorporated into our valuations, where appropriate, as of December 31, 2014 and 2013, the measurement dates. The methodologies used to determine the fair value of our financial assets and liabilities as of December 31, 2014 were the same as those used as of December 31, 2013.
	Fair values are estimates and are not necessarily indicative of amounts for which we could settle such instruments currently nor indicative of our intent or ability to dispose of or liquidate them.
	Assets and Liabilities Carried at Fair Value on a Recurring Basis
	Derivatives
	Derivatives, classified as Level 2, were primarily valued using estimated future cash flows based on observed prices from exchange-traded derivatives. We also considered the counterparty's creditworthiness, or our own creditworthiness, as appropriate. Adjustments were recorded to reflect the risk of credit default, but they were insignificant to the overall value of the derivatives. Refer to Note 8 for more information related to our derivative instruments.
	Marketable Equity Securities
	The following table presents the fair values of an investment in marketable equity securities, related to publicly traded stock of a non-U.S. company, recorded in Other assets, net in the accompanying Consolidated Balance Sheets (in millions):
		As of December 31,
		2014		2013
	Quoted Prices in Active Markets for Identical Assets (Level 1):
	Investment in marketable equity securities	$	5.3	$	4.4
	Other Fair Value Disclosures
	The carrying amounts of Cash and cash equivalents, Accounts and notes receivable, net, Accounts payable, Other current liabilities, and Short-term debt approximate fair value due to the short maturities of these instruments. The carrying amount of our Domestic Credit Facility in Long-term debt also approximates fair value due to its variable-rate characteristics.
	The fair value of our senior unsecured notes in Long-term debt was based on the amount of future cash flows using current market rates for debt instruments of similar maturities and credit risk. The following table presents the fair value for our senior unsecured notes in Long-term debt (in millions):
		As of December 31,
		2014		2013

	The Company’s senior unsecured notes are unconditionally guaranteed by certain of the Company’s subsidiaries (the “Guarantor
	Subsidiaries”) and are not secured by our other subsidiaries (the “Non-Guarantor Subsidiaries”). The Guarantor Subsidiaries are 100% owned, all guarantees are full and unconditional, and all guarantees are joint and several. As a result of the guarantee arrangements, we are required to present condensed consolidating financial statements.
	On March 22, 2013, the Company sold its Service Experts business to a majority-owned entity of American Capital, Ltd. The primary subsidiary for the U.S. Service Experts business had previously been included as a "Guarantor Subsidiary" and the Canada Service Experts subsidiary had previously been included as a "Non-Guarantor Subsidiary." As of December 31, 2014, the U.S. and Canada Service Experts businesses were included in discontinued operations of the condensed consolidating financial statements.
	The condensed consolidating financial statements reflect the investments in subsidiaries of the Company using the equity method of accounting. The principal elimination entries eliminate investments in subsidiaries and intercompany balances and transactions.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements include the accounts of Lennox International Inc. and our majority-owned subsidiaries. All intercompany transactions, profits and balances have been eliminated.
Cash and Cash Equivalents	Cash and Cash Equivalents
	We consider all highly liquid temporary investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents consisted primarily of bank deposits.
Accounts and Notes Receivable	Accounts and Notes Receivable
	Accounts and notes receivable are shown in the accompanying Consolidated Balance Sheets, net of allowance for doubtful accounts. The allowance for doubtful accounts is generally established during the period in which receivables are recognized and is based on the age of the receivables and management's judgment on our ability to collect. Management considers the historical trends of write-offs and recoveries of previously written-off accounts, the financial strength of customers and projected economic and market conditions. We determine the delinquency status of receivables predominantly based on contractual terms and we write-off uncollectible receivables after management's review of our ability to collect, as noted above. We have no significant concentrations of credit risk within our accounts and notes receivable.
Inventories	Inventories
	Inventory costs include material, labor, depreciation and plant overhead. Inventories of $212.9 million and $187.3 million as of December 31, 2014 and 2013, respectively, were valued at the lower of cost or market using the last-in, first-out (“LIFO”) cost method. The remainder of inventory is valued at the lower of cost or market with cost determined primarily using either the first-in, first-out (“FIFO”) or average cost methods.
	We elected to use the LIFO cost method for our domestic manufacturing companies in 1974 and continued to elect the LIFO cost method for new operations through the late 1980s. The types of inventory costs that use LIFO include raw materials, purchased components, work-in-process, repair parts and finished goods. Since the late 1990s, we have adopted the FIFO cost method for all new domestic manufacturing operations (primarily acquisitions). Our operating entities with a previous LIFO election continue to use the LIFO cost method. We use the FIFO cost method for our foreign-based manufacturing facilities.
Property, Plant and Equipment	Property, Plant and Equipment
	Property, plant and equipment is stated at cost, net of accumulated depreciation. Expenditures that increase the utility or extend the useful lives of fixed assets are capitalized while expenditures for maintenance and repairs are charged to expense as incurred.
	Depreciation is computed using the straight-line method over the following estimated useful lives:
	Buildings and improvements:
	Buildings and improvements	5 to 30 years
	Leasehold improvements	1 to 20 years
	Machinery and equipment:
	Computer hardware	3 to 5 years
	Computer software	3 to 10 years
	Factory machinery and equipment	1 to 15 years
	Research and development equipment	5 to 10 years
	Vehicles	3 to 8 years
	We periodically review long-lived assets for impairment as events or changes in circumstances indicate that the carrying amount of such assets might not be recoverable. To assess recoverability, we compare the estimated expected future undiscounted cash flows identified with each long-lived asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being reviewed, an impairment loss is recognized based on the excess of the carrying amount of the impaired assets over their fair value. See Note 5 for additional information on our property, plant and equipment.
Goodwill	Goodwill
	Goodwill represents the excess of cost over fair value of assets from acquired businesses. Goodwill is not amortized, but is reviewed for impairment annually and whenever events or changes in circumstances indicate the asset may be impaired.
	The annual goodwill impairment test was performed during the first quarter of 2014, and no impairment was recognized. During the third quarter of 2014, we changed the date of our annual goodwill impairment test from March 31st to December 31st. The change was made to more closely align the impairment testing date with the year-end results. The change in goodwill impairment testing date was deemed a change in accounting principle and did not delay, accelerate, or avoid a goodwill impairment charge. Management determined that the change in accounting principle was preferable under the circumstances and did not result in adjustments to our financial statements when applied retrospectively.
	The provisions of the accounting standard for goodwill allow us to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative goodwill impairment test. As part of our qualitative assessment, we monitor economic, legal, regulatory and other factors, industry trends, our market capitalization, recent and forecasted financial performance of our reporting units and the timing and nature of our restructuring activities for LII as a whole and for each reporting unit.
	For those reporting units which are evaluated using the two-step quantitative goodwill impairment test, we estimate reporting unit fair values using the discounted cash flow approach. The discounted cash flows used to estimate fair value are based on assumptions regarding each reporting unit’s estimated projected future cash flows and the estimated weighted-average cost of capital that a market participant would use in evaluating the reporting unit in a purchase transaction. The estimated weighted-average cost of capital is based on the risk-free interest rate and other factors such as equity risk premiums and the ratio of total debt to equity capital. In performing these impairment tests, we take steps to ensure that appropriate and reasonable cash flow projections and assumptions are used. We reconcile our estimated enterprise value to our market capitalization and determine the reasonableness of the cost of capital used by comparing to market data. We also perform sensitivity analyses on the key assumptions used, such as the weighted-average cost of capital and terminal growth rates. See Note 4 for additional information on our goodwill.
Intangible Assets	Intangible Assets
	We amortize intangible assets and other assets with finite lives over their respective estimated useful lives to their estimated residual values, as follows:
	Asset	Useful Life
	Deferred financing costs	Effective interest method
	Customer relationships	Straight-line method up to 12 years
	Patents and others	Straight-line method up to 20 years
	We periodically review intangible assets with estimable useful lives for impairment as events or changes in circumstances indicate that the carrying amount of such assets might not be recoverable. We assess recoverability by comparing the estimated expected undiscounted future cash flows identified with each intangible asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being reviewed, an impairment loss is recognized based on the excess of the carrying amount of the impaired assets over their fair value. In assessing the fair value of these intangible assets, we must make assumptions that a market participant would make regarding estimated future cash flows and other factors to determine the fair value of the respective assets. If these estimates or the related assumptions change, we may be required to record impairment charges for these assets in the future.
	We review our indefinite-lived intangible assets for impairment annually in the fourth quarter and whenever events or changes in circumstances indicate the asset may be impaired. The provisions of the accounting standard for indefinite-lived intangible assets allow us to first assess qualitative factors to determine whether it is necessary to perform a two-step quantitative impairment test. As part of our qualitative assessment, we monitor economic, legal, regulatory and other factors, industry trends, recent and forecasted financial performance of our reporting units and the timing and nature of our restructuring activities for LII as a whole and as they relate to the fair value of the assets. For those intangible assets which are evaluated using the two-step quantitative impairment test, we compare the estimated expected undiscounted future cash flows identified with each intangible asset or related asset group to the carrying amount of such assets. If the expected future cash flows do not exceed the carrying value of the asset or assets being reviewed, an impairment loss is recognized based on the excess of the carrying amount of the impaired assets over their fair value.
Product Warranties	Product Warranties
	For some of our heating, ventilation and air conditioning (“HVAC”) products, we provide warranty terms ranging from one to 20 years to customers for certain components such as compressors or heat exchangers. For select products, we also provide limited lifetime warranties. A liability for estimated warranty expense is recorded on the date that revenue is recognized. Our estimates of future warranty costs are determined by product line. The number of units we expect to repair or replace is determined by applying an estimated failure rate, which is generally based on historical experience, to the number of units that were sold and are still under warranty. The estimated units to be repaired under warranty are multiplied by the average cost to repair or replace such products to determine the estimated future warranty cost. We do not discount product warranty liabilities as the amounts are not fixed and the timing of future cash payments is neither fixed nor reliably determinable. We also provide for specifically-identified warranty obligations. Estimated future warranty costs are subject to adjustment depending on changes in actual failure rate and cost experience. Subsequent costs incurred for warranty claims serve to reduce the accrued product warranty liability. See Note 10 for more information on our estimated future warranty costs.
Pensions and Post-retirement Benefits	Pensions and Post-retirement Benefits
	We provide pension and post-retirement medical benefits to eligible domestic and foreign employees and we recognize pension and post-retirement benefit costs over the estimated service life or average life expectancy of those employees. We also recognize the funded status of our benefit plans, as measured at year-end by the difference between plan assets at fair value and the benefit obligation, in the Consolidated Balance Sheets. Changes in the funded status are recognized in the year in which the changes occur through accumulated other comprehensive income (“AOCI”). Actuarial gains or losses are amortized into net period benefit cost over the estimated service life of covered employees or average life expectancy of participants depending on the plan.
	The benefit plan assets and liabilities reflect assumptions about the long-range performance of our benefit plans. Should actual results differ from management's estimates, revisions to the benefit plan assets and liabilities would be required. See Note 12 for information regarding those estimates and additional disclosures on pension and post-retirement medical benefits.
Self Insurance	Self-Insurance
	Self-insurance expense and liabilities were actuarially determined based primarily on our historical claims information and industry factors and trends. The self-insurance liabilities as of December 31, 2014 represent the best estimate of the future payments to be made on reported and unreported losses for 2014 and prior years. The amounts and timing of payments for claims reserved may vary depending on various factors, including the development and ultimate settlement of reported and unreported claims. To the extent actuarial assumptions change and claims experience rates differ from historical rates, our liabilities may change. See Note 10 for additional information on our self-insured risks and liabilities.
Derivatives	Derivatives
	We use futures contracts and fixed forward contracts to mitigate our exposure to volatility in metal commodity prices and foreign exchange rates. We hedge only exposures in the ordinary course of business and do not hold or trade derivatives for profit. All derivatives are recognized in the Consolidated Balance Sheets at fair value and the classification of each derivative instrument is based upon whether the maturity of the instrument is less than or greater than 12 months. See Note 8 for more information on our derivatives.
Income Taxes	Income Taxes
	We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Unrecognized tax benefits are accounted for as required by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 740. See Note 9 for more information related to income taxes.
Revenue Recognition	Revenue Recognition
	Our revenue recognition practices for the sale of goods depend upon the shipping terms for each transaction. Shipping terms are primarily FOB Shipping Point and, therefore, revenue is recognized for these transactions when products are shipped to customers and title passes. Certain customers in our smaller operations, primarily outside of North America, have shipping terms where title and risk of ownership do not transfer until the product is delivered to the customer. For these transactions, revenue is recognized on the date that the product is received and accepted by such customers. We experience returns for miscellaneous reasons and record a reserve for these returns at the time we recognize revenue based on historical experience. Our historical rates of return are insignificant as a percentage of sales. We also recognize revenue net of sales taxes.
	For our businesses that provide services, revenue is recognized at the time services are completed. Our Commercial Heating & Cooling segment also provides sales, installation, maintenance and repair services under fixed-price contracts. Revenue for these services is recognized over the life of the contract.
	We engage in cooperative advertising, customer rebate, cash discount and other miscellaneous programs that result in payments or credits being issued to our customers. We record these customer discounts and incentives as a reduction of sales when the sales are recorded. For certain cooperative advertising programs, we also receive an identifiable benefit (goods or services) in exchange for the consideration given, and, accordingly, record a ratable portion of the expenditure to Selling, general and administrative (“SG&A”) expenses. All other advertising, promotions and marketing costs are expensed as incurred. See Note 23 for more information on these costs.
Cost of Goods Sold	Cost of Goods Sold
	The principal elements of cost of goods sold are components, raw materials, factory overhead, labor, estimated costs of warranty expense and freight and distribution costs.
Selling, General and Administrative Expenses	Selling, General and Administrative Expenses
	SG&A expenses include payroll and benefit costs, advertising, commissions, research and development, information technology costs, and other selling, general and administrative related costs such as insurance, travel, non-production depreciation and rent.
Stock-Based Compensation	Stock-Based Compensation
	We recognize compensation expense for stock-based arrangements over the required employee service periods. We measure stock-based compensation costs on the estimated grant-date fair value of the stock-based awards that are expected to ultimately vest and we adjust expected vesting rates to actual rates as additional information becomes known. For stock-based arrangements with performance conditions, we periodically adjust performance achievement rates based on our best estimates of those rates at the end of the performance period. See Note 14 for more information.
Translation of Foreign Currencies	Translation of Foreign Currencies
	All assets and liabilities of foreign subsidiaries and joint ventures are translated into U.S. dollars using rates of exchange in effect at the balance sheet date. Revenue and expenses are translated at weighted average exchange rates during the year. Unrealized translation gains and losses are included in AOCI in the accompanying Consolidated Balance Sheets. Transaction gains and losses are included in Losses and other expenses, net in the accompanying Consolidated Statements of Operations.
Use of Estimates	Use of Estimates
	The preparation of financial statements requires us to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangible assets and other long-lived assets, contingencies, product warranties, guarantee obligations, indemnifications, and assumptions used in the calculation of income taxes, pension and post-retirement medical benefits, and stock-based compensation among others. These estimates and assumptions are based on our best estimates and judgment.
	We evaluate these estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. We believe these estimates and assumptions to be reasonable under the circumstances and will adjust such estimates and assumptions when facts and circumstances dictate. Volatile equity, foreign currency and commodity markets and uncertain future economic conditions combine to increase the uncertainty inherent in such estimates and assumptions. Future events and their effects cannot be determined with precision and actual results could differ significantly from these estimates. Changes in these estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
