Heat pump vs Furnace in Park County, Montana
When a heat pump makes sense
A heat pump still makes sense if you want air conditioning along with heat, or if you don't have a gas line to the house. Get a cold-climate model, since standard heat pumps lose heating power once temperatures drop, and your winter nights average 13°F. Expect to run it alongside a backup heat source for the coldest stretches, and plan for higher electric bills than a gas furnace would give you.
When a furnace makes sense
If your home already has a gas line, a furnace is the cheaper way to heat it here. It costs at least 40% less to run than a heat pump at Montana's prices, and it keeps its full output no matter how cold the night gets. The tradeoff is that a furnace only heats, so you'd need a separate system for cooling.
