Heat pump vs Furnace in Washington County, Minnesota
When a heat pump makes sense
A heat pump makes sense if you want cooling and heating from one system, or if gas isn't an option at your address. Get a cold-climate model if you go this route. Standard heat pumps lose heating power once temperatures drop, and your winter nights average 10°F from December through February, so the machine needs to be built for that.
When a furnace makes sense
A furnace is the right call for most homes here. Natural gas costs at least 35% less to heat with than a heat pump at Minnesota prices, and with 8 months of heating a year that difference shows up on every bill. It won't cool your home in summer, so you would still need a separate air conditioner for that.

If your home has no gas line, a cold-climate heat pump still heats it through winter and cools it in summer without bringing gas in.
