Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The Unaudited Condensed Consolidated Financial Statements include all accounts of the Company and its wholly-owned and majority-owned subsidiaries in which it has control. Inter-company accounts and transactions have been eliminated. Related party transactions between the Company and its equity method investees have not been eliminated. Non-controlling interest represents a non-controlling investor's interests in the results of subsidiaries that the Company controls and consolidates. Portfolio Transformation During 2024, the Company completed several activities designed to simplify its business portfolio, transforming it into a pure-play climate and energy solutions provider. On January 2, 2024, the Company acquired the climate solutions business (the "VCS Business") of Viessmann Group GmbH & Co. KG (together with its affiliates, “Viessmann”). The VCS Business, primarily reported in the Climate Solutions Europe segment, is a premier residential and light commercial HVAC provider in Europe that expanded our portfolio to offer a global, comprehensive suite of sustainable and innovative building and cold-chain solutions. In addition, the Company divested its Commercial and Residential Fire, Access Solutions and Industrial Fire businesses which were historically reported in its Fire & Security segment. The transactions represented a single disposal plan to separately divest multiple businesses over different reporting periods and met the criteria to be presented as discontinued operations in the accompanying financial statements. The Company also divested its Commercial Refrigeration business (“CCR”) during 2024. CCR, which was historically reported in the Climate Solutions Transportation segment (previously named Refrigeration), did not meet the criteria to be presented as discontinued operations. Segment Reorganization As a result of the Company's portfolio transformation, the Company revised its reportable segments during the first quarter of 2025 to better reflect its business strategy, align its management reporting and increase transparency for investors. Under the revised segment structure, the Company has three new regional HVAC operating segments. Combined with the Climate Solutions Transportation operating segment, the four operating segments also serve as the Company's reportable segments. This model is designed to create a simplified, more focused and customer-centric organization across the globe. Each segment reports through separate management teams which regularly review their operating results with the Company's Chief Operating Decision Maker (the "CODM") determined in accordance with applicable accounting guidance. In connection with the revised structure, the CODM changed the measure used to evaluate segment profitability from Operating profit to Segment operating profit. All prior period comparative information has been recast to reflect the revised segment structure. See Note 17 – Segment Financial Data for additional information. Separation from United Technologies On April 3, 2020 (the "Distribution Date"), United Technologies Corporation ("UTC"), since renamed RTX Corporation ("Raytheon Technologies Corporation" or "RTX"), completed the spin-off of Carrier into an independent, publicly traded company (the "Separation") through a pro-rata distribution (the "Distribution") on a one-for-one basis of all of the outstanding shares of common stock of Carrier to UTC shareowners who held shares of UTC common stock as of the close of business on March 19, 2020, the record date of the Distribution. In addition, the Company entered into several agreements with UTC and Otis Worldwide Corporation ("Otis") that govern various aspects of the relationship among the Company, UTC and Otis. As of June 30, 2025, only certain portions of the Tax Matters Agreement ("TMA") remain in effect. Recently Issued and Adopted Accounting Pronouncements The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") is the sole source of authoritative U.S. GAAP other than SEC issued rules and regulations that apply only to SEC registrants. The FASB issues Accounting Standards Updates ("ASU") to communicate changes to the codification. The Company considers the applicability and impact of all ASUs. ASUs pending adoption were assessed and determined to be either not applicable or are not expected to have a material impact on the accompanying Unaudited Condensed Consolidated Financial Statements. Recently Issued Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures ("ASU 2023-09"), which requires public entities to disclose disaggregated information about their effective tax rate reconciliation as well as information on income taxes paid. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The ASU requires additional disclosures and is not expected to have a material impact on the Company's financial statements. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (DISE) ("ASU 2024-03"), which requires public entities to disclose disaggregated information about expenses by nature on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently assessing the impact of this ASU on its financial statements.
