Heat pump vs Furnace in Waukesha County, Wisconsin
When a heat pump makes sense
A heat pump makes sense if you want cooling and heating from one system and you plan to install a cold-climate model built for winters like this one. Standard heat pumps lose heating power as it gets colder, and nights here average 16°F from December through February, so that rating matters. It runs on electricity instead of gas, which costs more to heat with here, so weigh that against having central air built in.
When a furnace makes sense
A furnace fits most homes in this county, and the numbers explain why. Nights here average 16°F from December through February, well within what a furnace handles without losing output. Heating with gas costs at least 45% less than running a heat pump at Wisconsin's rates, and with heat needed about eight months a year, that difference adds up. It's also what most of your neighbors already have, since 77% of homes in the county heat with gas.
