Heat Pumps in Maine

A whole-home heat pump system in Maine typically costs $12,000–$22,000 installed before rebates. With the Efficiency Maine rebate of up to $3,000 plus income-qualified HEAR rebates (up to $8,000), net cost can be as low as $9,000–$19,000. Note: the federal 25C heat pump tax credit expired December 31, 2025.

For Maine's climate, we recommend Mitsubishi Hyper-Heat, Fujitsu Halcyon XLTH, LG Red Series. Cold-climate models are essential for Maine winters — standard heat pumps lose too much capacity below 20°F.

A typical Maine home switching from oil heating saves approximately $2,080 per year — from $2,900/year in oil to roughly $820/year with a heat pump. Savings are even greater when paired with solar panels, which can reduce heat pump operating costs to near zero.

Yes. Maine's winter design temperatures (cold to very cold winters with design temps of -5°f to -15°f) require cold-climate heat pumps (ccASHP) rated to operate below 0°F. Standard heat pumps lose significant capacity below 20°F and are not suitable for Maine as the primary heating source.

Efficiency Maine heat pump rebate up to $3,000 (up to $9,000 for income-eligible households). Additionally, income-qualified households may be eligible for HEAR (Home Electrification and Appliance Rebates) of up to $8,000 for low-income or $4,000 for moderate-income households.
