Dual-Fuel Heating in Minnesota: Heat Pump Plus Furnace
How a dual-fuel heat pump and furnace system works in Minnesota, and how to set the switchover temperature from your own gas and electric bills.
Read the guide
In Centerville, an installed heat pump runs $7,500–$14,500 on a written flat-rate quote. Most 1980s and 90s houses here already have a gas furnace and central air, so the common job swaps the old condenser for a cold-climate heat pump and keeps the furnace as backup.
Centerville grew quickly in the 1980s and 1990s, and whole streets of air conditioners went in within a few years of each other. Those condensers are now aging out together, which makes the AC replacement the natural moment to ask about a heat pump. The furnace in the basement mechanical room often stays, and the heat pump runs most of the season with the gas furnace handling deep cold as dual fuel.
If the furnace is also near the end, replacing both as a matched dual-fuel system saves doing the work twice. We walk the basement mechanical room, check the electrical panel and the condensate route, and write one quote that lists the equipment, electrical work and any venting changes.

Our $7,500–$14,500 installed price comes as a written flat-rate quote, with a 2-year labor warranty on top of the manufacturer's parts warranty. 1980s and 90s houses usually just swap the aging condenser for a cold-climate unit, so the price depends on whether the basement furnace stays as the dual-fuel backup. See the heat pump cost guide.

If both are 25 years old or more, replacing them together is usually sensible. A new cold-climate heat pump paired with a new condensing furnace gives you a dual-fuel system that works as a unit. If the furnace still runs well, keep it and replace only the AC with the heat pump. We check the heat exchanger and the age before saying which.
Often, after a look at the venting and ducts. Those houses have chimney venting and ductwork added in stages, so we check what the ducts can carry and whether the furnace stays as backup, then quote it in writing.
