Heat Pump Payback in Mount Pleasant, WI

Should Mount Pleasant switch to a heat pump?

Here in Mount Pleasant, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Running costs here land $278 a year higher than the furnace it replaces, so that premium is never recovered. That's Mount Pleasant's own climate and rates talking, not a hedge or a caveat.

How cold Mount Pleasant actually gets

Degree days tell the story here: Mount Pleasant racks up 5287 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 796 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 0°F here (coldest 2024 reading -9°F), which works out to a seasonal COP of 2.7 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, Mount Pleasant sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, John H Batten Airport, 5.1 miles from Mount Pleasant.

The yearly running costs in Mount Pleasant

Modelled on a typical 2000-square-foot house, the heat pump draws about 4,958 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,064 a year. The gas furnace it replaces burns roughly 55 Mcf a year at $10.74 per Mcf here, for a running cost near $786 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: $9,665 behind after 15 years compared with replacing the furnace and AC like-for-like.

How sensitive Mount Pleasant's result is to prices

For the verdict in Mount Pleasant to flip, electricity would need to drop to about 12.8¢/kWh from 18.87¢, or gas climb past $15.78 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 Mount Pleasant; the case for one here rests on comfort, cooling, or replacing electric heat instead.

The other scenario: no gas furnace to begin with

Gas isn't universal in Mount Pleasant, many houses run on electric heat already. 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 $1,657 a year, which recovers the extra $10,000 spent going electric in roughly 6 years.
