Heat pump vs. gas furnace in Adrian, MI
In Adrian, 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). The heat pump would cost about $307 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Adrian's numbers say wait.
The climate behind Adrian's payback figure
Adrian has a cold winter that leans hard on heating equipment — 5000 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 856 cooling degree days. 1.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -2.9°F on file. Worked through the model, that's a seasonal COP of 2.75 on the cold-climate unit fit for this climate. Adrian needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,604 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,105 a year. Adrian's gas rate of 10.92 per Mcf, applied to the 52 Mcf a year the furnace burns, puts its running cost near $799 a year, against 20.72¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $8,100 behind.
Electric resistance heat in Adrian, compared
Gas isn't universal in Adrian — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,748 a year, which recovers the extra $8,000 spent going electric in roughly 4.6 years.
Where Adrian ranks in this dataset
Among 3206 cities, Adrian's winter puts it at rank 702 for severity, while its size puts it at rank 1899 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.

Every constant behind this page — the 2.75 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Adrian's 1.9°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.
