Heat pump vs Furnace in Winnebago County, Illinois
When a heat pump makes sense
A heat pump makes sense if you want one system that heats and cools and you'd rather not rely on gas at all. Look for a cold-climate model, since standard heat pumps lose heating power once temperatures drop toward the 16°F nights this county sees from December through February. Plan on paying more to heat with electricity than a neighbor pays with gas at Illinois rates.
When a furnace makes sense
A furnace is the right call for most homes here. Winters run cold for about eight months, and a furnace holds its full heating power on the coldest night the same as a mild one, with no drop-off to plan around. It also costs at least 35% less to run than a heat pump at Illinois gas and electric rates, which is why 84% of homes here already heat this way.
