Eligibility varies by income, equipment efficiency, utility territory, and program funding availability.
Federal 25C/25D tax credits expired 12/31/2025. Federal DOE HEAR/HOMES administration ended 5/29/2026. State-run HEAR pathways that still print a dollar on an official page are listed with that URL and fetch date.
After-install rebates are claimed by the homeowner after installation and are not guaranteed at the point of sale.
