Jackson, MI: the heat pump payback math
Jackson 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 $3,500 after a $2,000 federal tax credit. Running costs here land $410 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Jackson's numbers say wait.
The climate behind Jackson's payback figure
Degree days tell the story here: Jackson racks up 5454 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 629 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -2.9°F, against a record low of -8°F. That puts the seasonal coefficient of performance at 2.63 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Jackson sits firmly in cold-climate territory, so that's the class of unit priced here.

Jackson's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 5,251 heating kilowatt-hours annually on top of cooling, totalling about $1,199 a year on electricity. That compares with roughly 57 Mcf a year of gas at Jackson's 10.92 per-Mcf rate — about $789 a year — against a local electricity rate of 20.72¢/kWh. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $9,649 behind.
Electric resistance heat in Jackson, compared
Not every home in Jackson has gas service. Swap the comparison to resistance heat instead of gas, and Jackson's answer improves. Switching saves about $1,831 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 4.4 years.
Jackson against the rest of the country
Among 3206 cities, Jackson's winter puts it at rank 403 for severity, while its size puts it at rank 1318 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.
Deciding what's next in Jackson, MI
About 30,920 people live in Jackson, 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.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Jackson's 2.63 seasonal COP and payback figure. Jackson's -2.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
