Heat pump vs Furnace in Linn County, Iowa
When a heat pump makes sense
If you want cooling as well as heating from one system, a heat pump gives you both. Look for a cold-climate model, since standard heat pumps lose heating power once temperatures drop toward 15°F, and that's a normal winter night here. Expect to run it alongside a backup heat source for the coldest stretches of December through February.
When a furnace makes sense
If your home already has a gas line, a furnace is the cheaper way to heat it. Natural gas costs at least 30 percent less than a heat pump at Iowa prices, and that gap matters over eight months of heating a year. A furnace also holds its output on the coldest nights, when temperatures average 15°F, without needing a backup.
