Heat pump vs Furnace in Dallas County, Iowa
When a heat pump makes sense
If you already have gas at the house, a heat pump still makes sense if you want cooling and heating from one system and you're set on a cold-climate model built to keep its heating power at 15°F and below. Standard heat pumps lose capacity in that kind of cold, so a cold-climate unit matters here, not the standard version. Even then, expect to pay more to run it than a gas furnace at Iowa gas prices.
When a furnace makes sense
For most homes here, the furnace is the one to install. It's built to hold its output no matter how far the temperature drops, which matters through a Dallas County winter, and it costs less to run than a heat pump at Iowa gas prices. With eight months of heating a year and most homes in this region already on gas, it's the choice that fits what's already at the house.

Furnace wins in Dallas County.
Winter nights here average 15°F, and gas heat costs at least 30% less than a heat pump at Iowa prices, so the furnace wins.
If your home has no gas line to work with, a cold-climate heat pump will still heat it through a 15°F night and cool it come summer.
