Heat pump vs Furnace in Silver Bow County, Montana
When a heat pump makes sense
A heat pump makes sense if you want air conditioning as well as heat and you are set on staying electric. Look for a cold-climate model, since standard heat pumps lose heating power at 14°F and that is a normal winter night here. Even then, expect to run natural gas costs at least 40% less, so budget for higher electric bills through the cold months.
When a furnace makes sense
A furnace is the right call if gas is already run to your house, which is true for most homes in the county. It keeps its full output no matter how cold the night gets, and with heat needed here nearly 11 months of the year, that steady output matters. It costs less to run on gas at Montana prices, though it will not cool your house in summer.
