Rebates & Incentives for Heat Pumps in Maine

Efficiency Maine, the federal government, and some local city and town municipalities offer heat pump rebates to all income types. In additional, solar programs and utility discount programs are now making heat pump systems more appealing than ever. With over 100,000 heat pumps installed in Maine, they are now more common than oil in new homes. Because heat pumps offer highly efficient heating, air conditioning, and dehumidification, heat pumps can serve as the primary heating and cooling system in a home.

Federal Government Incentives

A tax credit of up to $2,600 was put into effect for any projects billed as of January 1, 2023. The criteria for qualifying requires customers to have a tax liability of $2,000 or more on qualifying equipment. We are working with vendors to get an updated list of which equipment qualifies, so please contact us for more information. This credit resets each tax year, effectively becoming available again for additional projects.

Community Solar Program

Maine has programs available that allow citizens to benefit from the Community Solar projects around the state. Participating customers receive credits on their electric utility bill that reduces the amount of the payment owed to the utility, to the standard offer service provider, or, if applicable, to the customer’s competitive electricity provider. Typically signing up is free and customers can save up to 15% on their utility bills. Sounds good to go be true? It’s not!
