Efficiency Maine Heat Pump Rebate

Up to $8,000+ (whole-home cold-climate)

Efficiency Maine — the state-chartered nonprofit administering Maine's energy efficiency programs — runs one of the most generous heat pump rebate programs in the country. Whole-home cold-climate ASHP installs receive up to $8,000 in upfront rebate, with additional bonuses for low-income households and ground-source systems. Maine's heating market is uniquely opportunistic for heat pumps because the state's historical reliance on oil and propane heat (60%+ of homes) means heat pump electrification produces the largest absolute energy cost reduction in the US — typical Maine homeowners save $1,500–$3,000/year vs. their pre-heat-pump fuel bill.

Eligibility

Who qualifies?

Whole-home displacement?
