Help Homeowners Maximize 25C Tax Credits Before They Expire
HR1 or “The One Big Beautiful Bill Act” was passed by Congress and signed into law on July 4, 2025. The bill addressed tax cuts, spending increases, and policy changes, which impacted the 25C Energy Efficient Home Improvement Credit for residential furnaces, air conditioners, and heat pumps.
Congress expressed their intent to terminate the Section 25C homeowner energy efficiency tax credit at the end of this year. However, the final OBBBA as signed did not do that. The PIN requirement was removed instead. We expect this discrepancy to be addressed through a technical corrections bill in the coming months. We will continue to monitor closely and keep you informed of any updates. Until a technical correction bill is signed, the PIN requirement is eliminated and the 25C tax credit remains.
Regardless of 2026, homeowners can still take advantage of the 25C tax credits on qualifying HVAC equipment and systems if they purchase and install before December 31, 2025.
How Homeowners Can Save on Their HVAC Equipment
The Energy Efficient Home Improvement Tax Credit (25C) provides a federal tax credit to homeowners who install high-efficiency equipment, this includes HVAC equipment. The previous Nonbusiness Energy Property credit of up to $500 was extended through 2022. The amended Energy Efficient Home Improvement Credit , which began in 2023 and extends through 2032, increases the tax credits as high as $600 for qualified air conditioner or gas furnaces, and up to $2,000 for qualified heat pump, heat pump water heater, or boiler.

Performance level requirements of ACs, ASHPs, and Packaged Units have increased while requirements for gas furnaces will remain the same. See the tables below for the 2025 highest-tier requirements.
