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 $3,500 more up front here (already netting out a $2,000 tax credit). 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 record low of -1.7°F on file. 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 month-to-month numbers for 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 its running cost near $800 a year, against 20.72¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $8,003 behind.
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 4.5-year payback clears the $8,000 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.

About 15,480 people live in Mount Clemens, Michigan, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
