Program details
Efficiency Maine whole-home heat pump rebates
- Run by
- Efficiency Maine Trust
- Status
- Open
- What it covers
- Whole-home systems where heat pumps are the primary heat. The rebate pages and claim form say heat pumps must be sized for at least 80% of the peak heating load (ducted: 100%), a furnace or boiler may stay only as emergency backup, and dual-fuel systems aren’t eligible.
- Amounts
- Ducted whole-home: $9,000 (low income), $6,000 (moderate), $3,000 (any income). Non-ducted: $3,000, $2,000 or $1,000 per rebate-eligible outdoor unit, with lifetime limits ($9,000 / $6,000 / $3,000 per the residential rebate page). Plus “an additional $500 per housing unit” for whole-home upgrades completed and claimed March 1 through December 31, 2026.
- Income-qualified
- Higher amounts for lower incomes — low and moderate tiers require income verification, ideally before the claim
- On the quote or after?
- Rebate after installation. The claim form is signed by both the registered vendor and the homeowner, and the check can go to either. Low-income rebates go to the vendor, so check whether your quote already credits it.
- Before you sign
- Use an Efficiency Maine Residential Registered Vendor. Verify low or moderate income eligibility before the claim, or it may be paid at a lower tier. Claims are due within six months of completion.

Federal Home Energy Rebates (HEAR and HOMES) in Maine
Efficiency Maine runs Maine’s federal rebates. It lists HEAR as “Active”, but only for new affordable multifamily housing and mobile homes, so there is no general single-family federal heat pump rebate. Maine’s HOMES program (“HER”) was listed as “Conditionally Awarded”, not launched. See Efficiency Maine: IRA home energy rebates.
