Federal credit basics
ENERGY STAR publishes air-source heat-pump criteria for the federal energy-efficient home improvement credit, so product eligibility research should start with that official criteria page rather than a seller badge. source ↗
The IRS page says the Energy Efficient Home Improvement Credit applied to certain qualified expenses for improvements made after January 1, 2023 and through December 31, 2025, so 2026 shoppers should verify the current IRS status before assuming a new purchase qualifies. source ↗
This page is a pointer, not tax advice, because IRS rules, installation date, home use, tax liability, and product eligibility affect whether any credit can be claimed. source ↗
Rebate lookup
DOE lists home energy upgrade programs and points homeowners toward rebate access, so local rebate research should start with official DOE and state program pages rather than affiliate articles. source ↗
ENERGY STAR tax-credit criteria and DOE rebate programs are separate checks, so a shopper should verify both before assuming a single model qualifies for every incentive. source ↗ source ↗
Keep product certificates, invoices, installation records, and program screenshots with the project file because rebate administrators and tax filings may ask for documentation. source ↗ source ↗
