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.

Heat pump installation in Watertown runs $7,500–$14,500 with us, on a written quote after a load calculation. Xcel Energy supplies both the gas and the electricity inside the city, so one utility's rules cover the whole job.
Watertown is one of the towns where Xcel Energy sends both the gas bill and the electric bill, so a dual-fuel heat pump, a cold-climate unit paired with the existing gas furnace, deals with a single utility. Xcel's ducted heat pump rebates call for a Trade Partner Network contractor, and its AC Rewards program pays an annual reward for a connected smart thermostat, so ask what applies before you buy. The 2000s two-stories and split-entries that are now due for a first furnace and AC replacement are the usual candidates.
Out on Watertown Township acreage, homes often run on propane. A gas furnace rebate will not apply there, but a heat pump can still qualify on Xcel electric, and it can displace a lot of propane in spring and fall. Remember that a heat pump needs power like a furnace does: in a rural outage with a well, no electricity means no heat and no water, so plan the generator transfer switch with an electrician.

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. Acreage homes may need a generator transfer switch and a bigger dual-fuel setup, while a 2000s city house with sound ducts is the simplest and lowest-cost job. See the heat pump cost guide.

Often it does. A cold-climate heat pump, kept as dual fuel with the propane furnace, carries the shoulder seasons and many winter days, and the furnace takes over in the deepest cold. How much you save depends on the propane price against your Xcel electric rate, so the quote puts the heat pump next to a straight AC replacement.
It can. Rebate rules differ by equipment type and change yearly, and eligibility usually hangs on the exact model. We put model numbers on the written quote so the paperwork you send Xcel matches the equipment, ask Xcel whether the rebate needs a registered contractor before you sign.
