The federal HEAR rebate was renamed High-Efficiency Electric Home Rebates on May 29, 2026, and its rules were changed (https://www.energy.gov/documents/program-notice-26-2, fetched 2026-10-14). States run it, and many have not opened. Check your state energy office for current rebates.
After-install rebates are claimed by the homeowner after installation and are not guaranteed at the point of sale.
