Heat pump vs Furnace in Madison County, Idaho
When a heat pump makes sense
A heat pump makes sense if you want cooling as well as heat from one system, since it runs both. Get a cold-climate model, since standard heat pumps lose heating power in cold weather, and nights here average 14°F from December through February. You will still pay more to run it than a neighbor heating with gas, so weigh that against not needing a separate air conditioner.
When a furnace makes sense
A furnace is the safer bet if keeping your heating bill down matters most, since natural gas runs at least 30 percent cheaper here than a heat pump at current Idaho prices. Burning gas for heat does not lose output in cold weather the way a heat pump can. The tradeoff is that a furnace only heats, so you would still need a separate system for cooling.

Furnace wins in Madison County.
Winter nights here average 14°F, and gas heat costs at least 30% less than a heat pump at Idaho prices, so the furnace wins.
If your home has no gas line to it, a cold-climate heat pump will still heat it through those 14 degree nights and cool it come summer.
