What will Maine pay toward your heat pump?
Efficiency Maine rebates are now the main incentive: the federal heat pump tax credit ended December 31, 2025. Answer four questions for an estimate.
Estimated rebates
$3,500
- 3 outdoor units × $1,000
- $3,000
- Whole-home bonus (by Dec 31, 2026)
- $500
Efficiency Maine Home Energy Loans (up to $25,000, from 0% for 1 year) can finance the rest. Estimate only; amounts set by Efficiency Maine and subject to change.
Get matched with a registered installer
Rebates require an Efficiency Maine Residential Registered Vendor. We'll send your estimate to up to three in your area.
Rules worth knowing: Low- and moderate-income rebates require an owner-occupied primary residence and income verification before installation. Systems must be sized as whole-home heating. Lifetime limits per housing unit: $3,000 any income, $6,000 moderate, $9,000 low. Rebates change; Efficiency Maine's terms say incentives can be changed or ended. Confirm current amounts with Efficiency Maine (866-376-2463) or your installer. Estimates last checked November 2026.
