Heat pump vs Furnace in Washtenaw County, Michigan
When a heat pump makes sense
A heat pump makes sense if you want cooling and heating from one system and you already lean electric for other things in the house. Get a cold-climate model, since a standard heat pump loses heating power once temperatures drop toward what Washtenaw County sees on a typical winter night. Even then, expect to pay more to heat through the winter than you would with gas at Michigan prices.
When a furnace makes sense
A furnace is the right call for most homes here. Winter nights average 19°F from December through February, and heating with gas costs at least 50% less than a heat pump at Michigan prices. It only heats, so you would need a separate air conditioner for summer, but with about eight months of heating a year here, that trade favors the furnace for most homes.

Furnace wins in Washtenaw County.
Winter nights here average 19°F, and natural gas costs at least 50% less than a heat pump at Michigan prices, so gas furnaces are what most homes here run on.
If your home has no gas line to it, a cold-climate heat pump will still heat it through those 19°F nights and cool it come summer, all from one system.
