Heat pump vs Furnace in Sangamon County, Illinois

When a heat pump makes sense

A heat pump fits a home where you want one system for both heating and cooling, and you're willing to move off gas. Choose a cold-climate model. Standard heat pumps lose heating power once temperatures drop toward the 22°F this county sees on winter nights, and a cold-climate model is built to keep working through that. Expect higher winter heating costs than a gas furnace, since electricity runs at least 35% more here at Illinois prices.

When a furnace makes sense

A furnace suits most homes in this county, and 73% already heat this way. It costs at least 35% less to run than a heat pump here, which matters over the roughly seven months a year this county needs heat, including nights that average 22°F. The tradeoff is that a furnace only heats. You'll still need a separate system for summer cooling.
