| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | As demonstrated by the CAP vs. Cumulative TSR graph below, the amount of CAP to Mr. Gitlin and the average amount of CAP to the company’s NEOs as a group (excluding Mr. Gitlin) is aligned with the company’s cumulative TSR over the three years presented in the table. The alignment of CAP with the company’s cumulative TSR over the period presented is the result of a significant portion of the CAP to Mr. Gitlin and to the other NEOs being comprised of equity awards. As described in more detail in “Compensation Discussion and Analysis,” the company targets that more than 70% of the value of total compensation for Mr. Gitlin and more than 60% of the value of total compensation awarded to the other NEOs is to be comprised of equity awards, the value of which is 100% performance-based. In addition, since the company's Separation, 75% of the annual LTI Plan awards for Mr. Gitlin and the NEOs have been linked to stock price performance through the use of SARs and the relative TSR metric included in our PSUs. As reflected in the graphs below, both the company's TSR and our NEO's CAP both declined in 2022, despite continuing to deliver solid financial results and outpace comparators in the S&P 500 Index and Dow Jones Industrials Index. This further illustrates the strong correlation between delivering shareowner value and our NEO's CAP. Carrier Cumulative TSR vs. Cumulative TSR of Comparators 1 CAP vs. Cumulative TSR 1 This graph compares the cumulative TSR of our common stock against the cumulative total return of the S&P 500 Index and the Dow Jones Industrials Index for the period from April 3, 2020 to December 31, 2022, assuming in each case a fixed investment of $100 at the respective closing prices of April 3, 2020, the date of Carrier's Separation, including reinvestment of dividends. | | |
| Compensation Actually Paid vs. Net Income [Text Block] | As demonstrated by the graph below, the CAP to Mr. Gitlin and the average amount of CAP to the company’s NEOs as a group (excluding Mr. Gitlin) is generally aligned with the company’s net income over the years presented in the table, with the exception of 2022. In 2022, the CAP to Mr. Gitlin and the company's other NEOs declined, despite continuing to deliver solid financial results in the face of significant macroeconomic challenges, while the 2022 GAAP Net Income showed a significant increase versus 2021 due to proceeds received from the divestiture of the Chubb business, which occurred in January 2022. While the company does not use net income as a performance measure in the overall executive compensation program, the measure of net income is correlated with the measure of adjusted operating profit, which is a performance metric in the company's Annual Bonus Plan. As described in more detail in "Compensation Discussion and Analysis,” approximately 20% of the value of total target compensation awarded to the NEOs consists of amounts determined under the company's Annual Bonus Plan. CAP vs. GAAP Net Income | | |
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | As demonstrated by the following graph, the CAP to Mr. Gitlin and the average CAP to the company’s NEOs as a group (excluding Mr. Gitlin) is generally aligned with the company’s adjusted EPS over the three years presented in the table. Adjusted EPS represents diluted earnings per share (a GAAP measure), excluding restructuring costs, amortization of acquired intangibles and other significant items. While the company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the company’s compensation programs, the company has assessed and determined that adjusted EPS is the most important financial performance measure (that is not otherwise required to be disclosed in the table) used to link NEO's CAP to company performance. In support of this determination, the company utilizes adjusted EPS when setting goals in the company’s LTI compensation program, comprised of SARs and PSUs in 2022. The company targets that more than 70% of the value of total compensation for Mr. Gitlin and more than 60% of the value of total compensation awarded to the NEOs is to be comprised of equity awards, of which 100% is performance-based with a specific emphasis on stock price. 50% of the PSUs awarded to Mr. Gitlin and the NEOs are linked to the company's adjusted EPS CAGR over a three-year performance period. Adjusted EPS has increased each of the three years following the company's Separation in 2020, further highlighting the company's exceptional financial performance and creation of shareowner value during this time. As noted earlier, CAP declined in 2022 due to stock price decline, despite continuing to deliver solid financial results including a 3% increase in adjusted EPS. This increase in adjusted EPS was realized despite the sale of the Chubb business, and in the face of significant macroeconomic challenges. CAP vs. Adjusted EPS | | |

| Additional 402(v) Disclosure [Text Block] | Cumulative TSR is calculated by (i) dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment; and (ii) the difference between the company’s share price at the end and the beginning of the measurement period by the company’s share price at the beginning of the measurement period. The company’s TSR and Dow Jones Industrial Index TSR are calculated using a measurement period beginning at the Separation date of April 3, 2020, through and including the end of the applicable fiscal year and based on a fixed investment of $100 at the measurement point.The dollar amounts reported represent the amount of net income reflected in the company’s audited financial statements for the applicable year.While the company utilizes several performance measures to align executive compensation with company performance, not all of those performance measures are presented in the Pay Versus Performance Disclosure Table. Moreover, the company generally seeks to incentivize long-term performance, and therefore does not specifically align the company’s performance measures with CAP (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, the company is providing the following descriptions of the relationships between information presented in the Pay Versus Performance Disclosure Table. | | |
