Heat pump vs Furnace in Kootenai County, Idaho
When a heat pump makes sense
If your house already has gas run to it, a heat pump still makes sense when you want air conditioning built into the same system rather than a separate unit. Look for a cold-climate model, since standard heat pumps lose heating power once temperatures drop toward what your winter nights average here. Expect to run it alongside a backup heat source for the coldest stretches, and know that with Idaho electricity prices, running it will cost more than heating with gas.
When a furnace makes sense
If your home needs heat most of the year and gas service already runs to your house, a furnace is the cheaper machine to run here, by a wide enough margin that it holds up across a typical winter of nights near 25 degrees. It has no trouble keeping up in cold weather the way a standard heat pump can. The tradeoff is that it only heats, so you would still need a separate system for cooling.

Furnace wins in Kootenai County.
Gas heat runs at least 30% cheaper than a heat pump here, and most of your neighbors already heat with gas.
If your home has no gas line to it, a cold-climate heat pump still heats it through those 25°F nights, and gives you air conditioning besides.
