Heat pump vs Furnace in Warren County, Iowa
When a heat pump makes sense
If you want cooling and heating from one system, a heat pump gives you both. Choose a cold-climate model, since a standard heat pump loses heating power once temperatures drop toward 17°F, and that's a normal December night here. Weigh the higher electric running cost against the comfort of central air in summer, since gas heat here runs at least 30% cheaper through the winter.
When a furnace makes sense
If keeping winter bills down matters most, the furnace is the safer bet. Natural gas costs at least 30% less than a heat pump to run at Iowa prices, and that adds up over eight months of heating a year. A furnace holds its output no matter how cold the night gets outside, which matters when winter lows average 17°F. You will need a separate system for summer cooling, since a furnace only heats.

Furnace wins in Warren County.
Winter nights here average 17°F, and gas heat costs at least 30% less than a heat pump, so a furnace makes sense.
If your home has no gas line to work with, a cold-climate heat pump will still heat it through those 17°F nights and cool it come summer.
