Heat pump vs Furnace in Cumberland County, Maine
When a heat pump makes sense
If your home already has gas heat isn't an option, or you want cooling from the same system, a cold-climate heat pump is built to keep working through nights at 15°F. Look for a cold-climate model specifically, since standard heat pumps lose heating power once temperatures drop this low. Expect to pay more to run it than a gas furnace at Maine's prices.
When a furnace makes sense
If natural gas runs to your home, a furnace is the cheaper way to heat it here, at least 25% less than a heat pump at current prices. With nine months of heating season and winter nights averaging 15°F, that savings adds up over a long, cold stretch. A furnace only heats, so you would still need a separate system for cooling.
