Heat Pump Payback in River Falls, WI
Is a heat pump worth it in River Falls?
Here in River Falls, the honest answer is that a heat pump raises your annual running cost. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Unfortunately the electric bill outweighs the gas bill it replaces by about $394 a year here, so the extra spend stays unrecovered. There's no spin on that: River Falls's numbers say wait.

Why River Falls's climate drives this number
6060 heating degree days pile up here every year, so River Falls has a cold winter that leans hard on heating equipment; the cooling side runs to 712 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: -5.8°F here (coldest 2024 reading -8.3°F), which works out to a seasonal COP of 2.56 for the cold-climate class of unit this climate calls for. River Falls needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from South St Paul Muni-Richard E, the closest NOAA station, 19.9 miles out.
The yearly running costs in River Falls
Electricity use for heating alone comes out to about 5,994 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,246 a year. The gas furnace it replaces burns roughly 63 Mcf a year at $10.74 per Mcf here, for a running cost near $852 a year including the old AC (electricity here runs 18.87¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $11,405 behind.
What would change River Falls's answer
The heat pump would become the cheaper option in River Falls if electricity fell to 11.9¢/kWh (from 18.87¢) or gas rose above $16.98 per Mcf (from $10.74). At today's prices a cheaper quote cannot rescue the gas comparison in River Falls, since there is no yearly saving to recover it from.
If your home heats with electric baseboard instead of gas
Plenty of homes in River Falls heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,824 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 5.5 years.

Every constant behind this page, the 2.56 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. River Falls's -5.8°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here, see what that changes in the cold-climate unit guide.
