Heat pump vs Furnace in Nez Perce County, Idaho
When a heat pump makes sense
If you want cooling as well as heat from one system, a heat pump gives you both. Get a cold-climate model, not a standard one, since standard heat pumps lose heating power once temperatures drop toward that 26°F average you see on winter nights here. Expect to pay more to run it than a gas furnace, since gas costs at least 30% less at Idaho prices.
When a furnace makes sense
If your home already has a gas line, a furnace is the cheaper machine to run through the long heating season here. It costs at least 30% less than a heat pump to heat with at Idaho prices, and it holds its output no matter how cold the night gets outside. It will not cool your home in summer, so you would need a separate air conditioner for that.
