Heat Pump Replacement & Upgrades
in Raymond, Maine

In Raymond, electricity is already the main heating fuel for about 15% of occupied homes. Some of that is modern heat pumps, and some is electric baseboard in camps that were wired for occasional use and later lived in year-round. Both are good candidates for an upgrade. Baseboard converts every kilowatt-hour into one kilowatt-hour of heat, while a cold-climate heat pump moves heat from outdoor air and delivers more heat for the same electricity, so replacing resistance heat usually shows up on the bill quickly.

Aging heat pumps are the other half of the work. A unit installed ten or more years ago may have lost capacity, grown noisy, or simply never been designed for the coldest nights. We service every brand, not just systems we installed, so the first visit can be a diagnosis rather than a sales pitch. If heat pump repair makes more sense than replacement, we will say so. When replacement is the better call, we compare current Mitsubishi, Daikin and Samsung cold-climate models against your load calculation.

Oil still heats about half of Raymond's homes, and the town's high share of other fuels and wood means plenty of houses run a stove or secondary system too. If heat pumps become your primary heat under Efficiency Maine's whole-home program, as of mid-2026, the oil boiler or propane furnace may stay installed, but only as emergency backup. By Efficiency Maine's math at June 2026 fuel and power prices, switching from propane to heat pumps saves on the order of $1,387 a year.

Refrigerant lines are not automatically reused. An existing line set stays only if it passes inspection and a pressure test and is the right size for the new equipment. Old pads get the same scrutiny, since frost heave near the lake can tip a unit over a few winters.

Households that burn wood often want to keep the stove for outages or simply for the fire. That can sit alongside a heat pump system, but for the whole-home rebate the heat pumps themselves still have to be sized for at least 80% of the peak load, so the stove becomes a choice rather than a necessity. As the house gets tighter through insulation and air sealing, we also look at fresh air, since an energy recovery ventilator can bring it in without dumping the heat you just paid for.
