Switching From Propane to a Heat Pump in Rural Minnesota
Adding a heat pump to a propane-heated Minnesota home: keep the furnace as backup, compare gallons to kilowatt-hours, and ask your co-op the right questions.

A heat pump installed in a Richfield house runs $7,500–$14,500, flat-rate in writing, often swapped for a 1940s–50s house's old AC. Because the airport noise program already put central air and a tighter envelope into many 1940s and 50s houses, the install is often a swap of the existing air conditioner for a heat pump.
Richfield's postwar ramblers and story-and-a-halves are small, and many near the flight paths were sealed up through the airport noise program, which also installed their central air. That helps a heat pump. A tight house with a modest load can be served by a smaller unit, and the existing coil, line-set route and duct trunk are often reusable. We run a Manual J load calculation first, because the program's windows and attic insulation changed what the house needs compared with its 1950s original.
The usual plan is dual fuel: the heat pump carries the mild months and the CenterPoint gas furnace takes over when it gets very cold. The basements are low, so we check headroom for the new coil and where the condensate drains. Narrow lots mean the outdoor unit sits close to a property line or a neighbor's window, so sound rating and defrost drainage count. If you are planning an addition, size the system for the finished house, not the old one.

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. Airport-program houses are tight and small, so a Manual J calculation can pick a smaller unit, and the existing coil, line-set route and trunk are often reusable. See the heat pump cost guide.
For Xcel's AC and heat pump rebates, ask whether a registered contractor is required. Rebate programs change every year, so check the utility's current terms before you buy.

Often. The line set and duct trunk usually stay, while the outdoor unit and indoor coil are swapped for matched heat pump parts. What we check is the age of the program-installed system, whether the line set is clean and sound, and whether the blower and ducts can move the airflow a heat pump wants. We measure that and give you a written, flat-rate quote before any work starts.
Yes, or at least plan around it. A second story or rear addition changes the heating and cooling load a lot, and a unit sized for the original one-story house can come up short. We size the heat pump for the finished floor area and tell you whether the new space needs duct extensions or its own system.
