Heat pump vs Furnace in Lake County, Indiana
When a heat pump makes sense
A heat pump makes sense if you want one system for both heating and cooling and you'd rather not rely on gas at all. Choose a cold-climate model. Standard heat pumps lose heating power once temperatures drop toward 20°F, and that's a normal winter night here from December through February. Expect higher running costs than a neighbor heating with gas at Indiana rates.
When a furnace makes sense
A furnace is the right call for most homes in Lake County. It costs at least 40% less to run than a heat pump at Indiana gas prices, and it holds its full output no matter how cold the night gets. That's likely why 86% of homes here already heat with gas. The one thing it won't do is cool your house, so you'd still need a separate air conditioner for summer.

Furnace wins in Lake County.
Winter nights here average 20°F, and gas heat costs at least 40% less than a heat pump at Indiana prices, which is why most homes here heat with gas.
If your home has no gas line, a cold-climate heat pump will still heat it through a 20°F night and cool it come summer.
