Whole Home Heat Pump Incentives

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.
