Maine Energy Rebates 2026
Maine homeowners in 2026 can access federal HEAR and HOMES rebates plus Efficiency Maine Trust rebates — one of the country's most robust state efficiency programs offering heat pump rebates regardless of income. Maine has the highest heat pump adoption rate per capita in the United States, driven by oil-heating replacement economics and Efficiency Maine's long-running incentive programs. The 25C and 25D federal tax credits expired December 31, 2025.

Frequently Asked Questions
What energy rebates are available in Maine in 2026?
Maine homeowners in 2026 can stack multiple incentives: (1) Efficiency Maine heat pump rebates up to $2,000 for qualifying ducted systems, regardless of income; (2) Federal HEAR rebates for heat pumps (up to $8,000), heat pump water heaters ($1,750), insulation ($1,600), and electrical panels ($4,000) for income-qualified households (≤150% AMI); (3) HOMES whole-home performance rebates up to $8,000; (4) Efficiency Maine heat pump water heater rebates; (5) Free weatherization services for income-qualified households. The 25C and 25D federal tax credits expired December 31, 2025.
Are federal tax credits still available in Maine?
No. The One Big Beautiful Bill Act (OBBBA, P.L. 119-21, signed July 4, 2025) terminated the Section 25C and 25D federal energy tax credits for installations after December 31, 2025. If you installed qualifying equipment before that date, you can still claim the credit on your 2025 tax return. For 2026 installations, HEAR, HOMES, and Efficiency Maine rebates are the primary incentive paths.
Why does Maine lead the nation in heat pump installations?
Maine has several factors driving exceptional heat pump adoption: (1) very high oil dependency — Maine has the highest percentage of oil-heated homes in the US (over 50%); (2) Efficiency Maine's long-running heat pump rebate program (since 2014) built a large trained contractor network; (3) Maine's cold-climate heat pump expertise is among the best in the country; (4) high electricity rates (~20¢/kWh) are offset by heat pump efficiency advantages; (5) HEAR and HOMES federal rebates layer on top of Efficiency Maine rebates. Oil replacement economics are compelling: many homes cut heating costs in half.
How do Efficiency Maine rebates work with HEAR?
They can be stacked. Efficiency Maine rebates (up to $2,000 for qualifying ducted systems) are available regardless of income to all Maine households. For households at or below 150% AMI, federal HEAR rebates (up to $8,000 for heat pumps) can be added on top. This means an income-qualifying household could receive up to $10,000 in combined rebates on a cold-climate heat pump installation, dramatically reducing net cost.
What are the best cold-climate heat pumps for Maine winters?
Efficiency Maine requires qualifying heat pumps to meet cold-climate ENERGY STAR specs, maintaining rated performance at -13°F (-25°C). Top-performing models from Mitsubishi, Fujitsu, Bosch, and Daikin have performed well in Maine's climate. Efficiency Maine publishes a list of currently qualifying heat pump models on their website (efficiencymaine.com). Working with a Registered Vendor on Efficiency Maine's list ensures the equipment qualifies for rebates and that installers are experienced with Maine-specific cold-climate requirements.
