Heat Pump Payback in Mount Clemens, MI
Is a heat pump worth it in Mount Clemens?
In Mount Clemens, 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 $300 a year here, so the extra spend stays unrecovered. There's no spin on that: Mount Clemens's numbers say wait.

Why Mount Clemens's climate drives this number
Mount Clemens has a cold winter that leans hard on heating equipment, 5098 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 819 cooling degree days. 4.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -1.7°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.8 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Mount Clemens sits firmly in cold-climate territory, so that's the class of unit priced here.

The yearly running costs in Mount Clemens
A 2000-square-foot house here would pull roughly 4,610 heating kilowatt-hours annually on top of cooling, totalling about $1,100 a year on electricity. Mount Clemens's gas rate of $10.92 per Mcf, applied to the 53 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $800 a year, against 20.72¢ per kWh for electricity. 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 $10,003 behind.
What would change Mount Clemens's answer
The heat pump would become the cheaper option in Mount Clemens if electricity fell to 13.7¢/kWh (from 20.72¢) or gas rose above $16.57 per Mcf (from $10.92). At today's prices a cheaper quote cannot rescue the gas comparison in Mount Clemens, since there is no yearly saving to recover it from.
Electric resistance heat in Mount Clemens, compared
Not every home in Mount Clemens 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. About $1,795 a year comes back this way, enough that the 5.6-year payback clears the $10,000 premium comfortably within the equipment's life.
How Mount Clemens compares nationally
Among 3206 cities, Mount Clemens's winter puts it at rank 597 for severity, while its size puts it at rank 2348 for population, 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
