Federal 25C Energy Efficient Home Improvement Credit
30% of qualifying equipment + install cost back as a federal tax credit. $2,000 ceiling for heat pumps; $600 for furnaces and AC.
The 25C Energy Efficient Home Improvement Credit lets you claim 30% of qualifying HVAC equipment and installation costs as a non-refundable federal tax credit. Heat pumps and heat pump water heaters have a $2,000 annual ceiling; furnaces, boilers, and central air conditioners are capped at $600 each.
Unlike a rebate, the credit comes back when you file taxes — so it stacks cleanly on top of any Energize CT instant rebate. We provide a Manufacturer's Certification Statement and itemized invoice with every install, which is what you'll need at tax time.
Eligibility
- Equipment must meet CEE Highest Efficiency Tier (we only quote qualifying systems)
- Installed in an existing primary residence in the US
- Available annually through 2032
- Non-refundable — credit can't exceed your tax liability for the year
