Heat Pump Savings Calculator in Maine
Compare heat pump and furnace heating costs in Maine. Uses local climate data (7500 HDD), electricity rates, and fuel prices for accurate savings estimates.
What Maine Residents Should Know
Maine falls in IECC climate zone 6A with 7,500 heating degree days per year — well above the national average. Maine's cold winters mean heat pump COP averages 2 during the heating season. While this is lower than milder states, modern cold-climate heat pumps with inverter compressors can still deliver meaningful savings over traditional heating systems, especially when paired with a backup for the coldest days.
With natural gas at $1.75 per therm in Maine, a gas furnace may have lower operating costs in the coldest months. However, heat pumps provide both heating and cooling in one system, which can offset the difference when you factor in AC savings. In shoulder seasons (spring and fall), a heat pump is significantly more efficient, often making the overall annual cost competitive with gas.
Maine residents can access up to $4000 in state rebates and incentives for heat pump installations, in addition to the federal 25C energy efficient home improvement credit. These incentives can significantly reduce the upfront installation cost, which typically ranges from $4,000 to $8,000 depending on system size and complexity. Run the calculator above with your home details to see your personalized payback estimate.
