BASIS OF PRESENTATION

BASIS OF PRESENTATION	6 Months Ended
	Jun. 30, 2024
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION Basis of Consolidation Watsco, Inc. (collectively with its subsidiaries, “Watsco,” the “Company,” “we,” “us,” or “our”) was incorporated in Florida in 1956 and is the largest distributor of air conditioning, heating and refrigeration equipment and related parts and supplies (“HVAC/R”) in the HVAC/R distribution industry in North America. The accompanying June 30, 2024 interim condensed consolidated unaudited financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, but we believe the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation have been included in the condensed consolidated unaudited financial statements included herein. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our 2023 Annual Report on Form 10-K. The condensed consolidated unaudited financial statements include the accounts of Watsco, all of its wholly owned subsidiaries, the accounts of four joint ventures with Carrier Global Corporation, which we refer to as Carrier, in which we have a controlling interest, the accounts of Carrier InterAmerica Corporation and Carrier (Puerto Rico), Inc., in each of which we have an 80% controlling interest, and Carrier has a 20% non-controlling The results of operations for the quarter and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024. Sales of residential central air conditioners, heating equipment, and parts and supplies are seasonal. Furthermore, profitability can be impacted favorably or unfavorably based on weather patterns, particularly during the Summer and Winter selling seasons. Demand related to the residential central air conditioning replacement market is typically highest in the second and third quarters, and demand for heating equipment is usually highest in the first and fourth quarters. Demand related to the new construction sectors throughout most of the markets we serve tends to be fairly evenly distributed throughout the year and depends largely on housing completions and related weather and economic conditions. Short-Term Cash Investments Short-term cash investments consist of a certificate of deposit that matures in September 2024. Equity Method Investments Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in investment in unconsolidated entity in our condensed consolidated unaudited balance sheets. Under this method of accounting, our proportionate share of the net income or loss of the investee is included in other income in our condensed consolidated unaudited statements of income. The excess, if any, of the carrying amount of our investment over our ownership percentage in the underlying net assets of the investee is attributed to certain fair value adjustments with the remaining portion recognized as goodwill. Use of Estimates The preparation of condensed consolidated unaudited financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated unaudited financial statements and the reported amounts of revenues and expenses for the reporting period. Significant estimates include valuation reserves for accounts receivable, net realizable value adjustments to inventories, income taxes, reserves related to loss contingencies and the valuation of goodwill, indefinite-lived intangible assets, and long-lived assets. While we believe that these estimates are reasonable, actual results could differ from such estimates. Recently Adopted Accounting Standards Segment Reporting In September 2023, the Financial Accounting Standards Board (“FASB”) issued guidance that enhances segment reporting primarily by expanding the disclosures about significant segment expenses. Under the new standard, an entity will be required to disclose significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), how the CODM assesses segment performance and decides how to allocate resources, the title and position of the CODM, and certain other disclosures. This guidance is effective prospectively and is effective for annual periods beginning after December 15, 2023 and for interim periods beginning after December 15, 2024. The adoption of this guidance on January 1, 2024 did not have a material impact on our consolidated financial statements. Recently Issued Accounting Standards Not Yet Adopted Income Taxes In December 2023, the FASB issued guidance that enhances annual income tax disclosures primarily by disaggregating the existing disclosures related to the effective tax rate reconciliation and income taxes paid. Under the new guidance, an entity will be required to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. An entity will also be required to disclose the amount of income taxes paid disaggregated by federal, state and foreign, and by individual jurisdictions equal or greater than five Climate Disclosures In March 2024, the Securities and Exchange Commission (“SEC”) adopted rules to enhance and standardize disclosures related to the impacts and risks of climate-related matters. Under the new rules, an entity will be required to disclose information about climate-related risks that have materially impacted, or are likely to have a material impact, on its business strategy, results of operations, or financial condition. In addition, certain disclosures related to severe weather events, other natural conditions, and greenhouse gas emissions will be required in the audited financial statements. These rules are effective prospectively and are effective for annual periods beginning with the year ending December 31, 2025. On April 4, 2024, the SEC announced that it will stay implementation of its final rules pending the results of a legal challenge. We will continue to assess the impact of these rules on our consolidated financial statements while the stay is in place.

DERIVATIVES	6. DERIVATIVES We enter into foreign currency forward and option contracts to offset the earnings impact that foreign exchange rate fluctuations would otherwise have on certain monetary liabilities that are denominated in nonfunctional currencies. Derivatives Not Designated as Hedging Instruments We have entered into foreign currency forward and option contracts that are either not designated as hedges or did not qualify for hedge accounting.

COMMITMENTS AND CONTINGENCIES	9. COMMITMENTS AND CONTINGENCIES Litigation, Claims, and Assessments We are involved in litigation incidental to the operation of our business. We vigorously defend all matters in which we or our subsidiaries are named defendants and, for insurable losses, maintain significant levels of insurance to protect against adverse judgments, claims or assessments that may affect us. Although the adequacy of existing insurance coverage and the outcome of any legal proceedings cannot be predicted with certainty, based on the current information available, we do not believe the ultimate liability associated with any known claims or litigation will have a material adverse effect on our financial condition or results of operations. Self-Insurance Self-insurance reserves are maintained relative to company-wide casualty insurance and health benefit programs. The level of exposure from catastrophic events is limited by the purchase of stop-loss and aggregate liability reinsurance coverage. When estimating the self-insurance liabilities and related reserves, management considers several factors, which include historical claims experience, demographic factors, severity factors, and valuations provided by independent third-party actuaries. Management reviews its assumptions with its independent third-party actuaries to evaluate whether the self-insurance reserves are adequate. If actual claims or adverse development of loss reserves occur and exceed these estimates, additional reserves may be required. Reserves in the amounts of $9,531 and $9,747 at June 30, 2024 and December 31, 2023, respectively, were established related to such programs and are included in accrued expenses and other current liabilities in our condensed consolidated unaudited balance sheets.

Accounting Policies [Abstract]
Basis of Consolidation	Basis of Consolidation Watsco, Inc. (collectively with its subsidiaries, “Watsco,” the “Company,” “we,” “us,” or “our”) was incorporated in Florida in 1956 and is the largest distributor of air conditioning, heating and refrigeration equipment and related parts and supplies (“HVAC/R”) in the HVAC/R distribution industry in North America. The accompanying June 30, 2024 interim condensed consolidated unaudited financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations, but we believe the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation have been included in the condensed consolidated unaudited financial statements included herein. These statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our 2023 Annual Report on Form 10-K. The condensed consolidated unaudited financial statements include the accounts of Watsco, all of its wholly owned subsidiaries, the accounts of four joint ventures with Carrier Global Corporation, which we refer to as Carrier, in which we have a controlling interest, the accounts of Carrier InterAmerica Corporation and Carrier (Puerto Rico), Inc., in each of which we have an 80% controlling interest, and Carrier has a 20% non-controlling The results of operations for the quarter and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024. Sales of residential central air conditioners, heating equipment, and parts and supplies are seasonal. Furthermore, profitability can be impacted favorably or unfavorably based on weather patterns, particularly during the Summer and Winter selling seasons. Demand related to the residential central air conditioning replacement market is typically highest in the second and third quarters, and demand for heating equipment is usually highest in the first and fourth quarters. Demand related to the new construction sectors throughout most of the markets we serve tends to be fairly evenly distributed throughout the year and depends largely on housing completions and related weather and economic conditions.
Short-Term Cash Investments	Short-Term Cash Investments Short-term cash investments consist of a certificate of deposit that matures in September 2024.
Equity Method Investments	Equity Method Investments Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in investment in unconsolidated entity in our condensed consolidated unaudited balance sheets. Under this method of accounting, our proportionate share of the net income or loss of the investee is included in other income in our condensed consolidated unaudited statements of income. The excess, if any, of the carrying amount of our investment over our ownership percentage in the underlying net assets of the investee is attributed to certain fair value adjustments with the remaining portion recognized as goodwill.
Use of Estimates	Use of Estimates The preparation of condensed consolidated unaudited financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated unaudited financial statements and the reported amounts of revenues and expenses for the reporting period. Significant estimates include valuation reserves for accounts receivable, net realizable value adjustments to inventories, income taxes, reserves related to loss contingencies and the valuation of goodwill, indefinite-lived intangible assets, and long-lived assets. While we believe that these estimates are reasonable, actual results could differ from such estimates.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Segment Reporting In September 2023, the Financial Accounting Standards Board (“FASB”) issued guidance that enhances segment reporting primarily by expanding the disclosures about significant segment expenses. Under the new standard, an entity will be required to disclose significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), how the CODM assesses segment performance and decides how to allocate resources, the title and position of the CODM, and certain other disclosures. This guidance is effective prospectively and is effective for annual periods beginning after December 15, 2023 and for interim periods beginning after December 15, 2024. The adoption of this guidance on January 1, 2024 did not have a material impact on our consolidated financial statements.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Not Yet Adopted Income Taxes In December 2023, the FASB issued guidance that enhances annual income tax disclosures primarily by disaggregating the existing disclosures related to the effective tax rate reconciliation and income taxes paid. Under the new guidance, an entity will be required to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. An entity will also be required to disclose the amount of income taxes paid disaggregated by federal, state and foreign, and by individual jurisdictions equal or greater than five Climate Disclosures In March 2024, the Securities and Exchange Commission (“SEC”) adopted rules to enhance and standardize disclosures related to the impacts and risks of climate-related matters. Under the new rules, an entity will be required to disclose information about climate-related risks that have materially impacted, or are likely to have a material impact, on its business strategy, results of operations, or financial condition. In addition, certain disclosures related to severe weather events, other natural conditions, and greenhouse gas emissions will be required in the audited financial statements. These rules are effective prospectively and are effective for annual periods beginning with the year ending December 31, 2025. On April 4, 2024, the SEC announced that it will stay implementation of its final rules pending the results of a legal challenge. We will continue to assess the impact of these rules on our consolidated financial statements while the stay is in place.
