Heat Pump Payback in Eau Claire, WI
Is a heat pump worth it in Eau Claire?
In Eau Claire, a heat pump would cost more to run each year than what you have now. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Unfortunately the electric bill outweighs the gas bill it replaces by about $477 a year here, so the extra spend stays unrecovered. That's Eau Claire's own climate and rates talking, not a hedge or a caveat.

How cold Eau Claire actually gets
6356 heating degree days pile up here every year, so Eau Claire has a cold winter that leans hard on heating equipment; the cooling side runs to 558 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: -9.9°F here (coldest 2024 reading -11.9°F), which works out to a seasonal COP of 2.46 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Eau Claire sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from Chippewa Valley Regional Airport, the closest NOAA station, 3.4 miles out.
The yearly running costs in Eau Claire
Modelled on a typical 2000-square-foot house, the heat pump draws about 6,542 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,324 a year. The gas furnace it replaces burns roughly 66 Mcf a year at $10.74 per Mcf here, for a running cost near $847 a year including the old AC (electricity here runs 18.87¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $12,654 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Eau Claire's answer
For the verdict in Eau Claire to flip, electricity would need to drop to about 11.3¢/kWh from 18.87¢, or gas climb past $17.94 per Mcf from $10.74. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Eau Claire; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Eau Claire, compared
Not every home in Eau Claire has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,849 a year, which recovers the extra $10,000 spent going electric in roughly 5.4 years.
Where Eau Claire ranks in this dataset
Eau Claire lands at position 105 out of 3206 cities on heating severity (coldest is 1), and 532 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.

More on how this number was built
Every constant behind this page, the 2.46 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Eau Claire's -9.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
