Heat Pump Payback in Mount Pleasant, MI
Is a heat pump worth it in Mount Pleasant?
Mount Pleasant is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Running costs here land $409 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.

Mount Pleasant's weather, in the numbers that matter
5837 heating degree days pile up here every year, so Mount Pleasant has a cold winter that leans hard on heating equipment; the cooling side runs to 575 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 1°F, and the coldest daily reading in the 2024 station record was -5.4°F. That puts the seasonal coefficient of performance at 2.72 for the recommended cold-climate unit. 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. These numbers come from Mount Pleasant Municipal Airport, the closest NOAA station, 2.6 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 5,434 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,227 a year. The gas furnace it replaces burns roughly 61 Mcf a year at $10.92 per Mcf here, for a running cost near $818 a year including the old AC (electricity here runs 20.72¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $11,639 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 20.72¢, or gas climb past $17.65 per Mcf from $10.92. 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. Switching saves about $1,989 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 years.
How Mount Pleasant compares nationally
Ranked against the other 3206 cities covered, Mount Pleasant comes in at 278 for heating severity, 1 would be the coldest place in the dataset, and 1837 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Mount Pleasant's figure comes from
Every constant behind this page, the 2.72 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Mount Pleasant's 1°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.
