Residential Heat Pump Incentives

For customers who will use heat pumps as their primary heating system

REBATE CLAIM FORM
 

Over 100,000 heat pumps have been installed in Maine and they are now more common than oil heat in new homes (source: 2021 Maine New Construction Baseline Assessment). They are the most popular heating system across all of Efficiency Maine’s rebates because they offer highly efficient heating, air conditioning, and dehumidification.
