Canton, GA: the heat pump payback math
Canton sits right on the fence — how long you'll own the house decides this one. $3,500 is what Canton would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Canton's residents would see roughly $344 a year back in running costs, putting the payback around 10.2 years. Whether that's worth it in Canton depends on how many years you expect to own the place.
Why Canton's climate drives this number
2821 heating degree days pile up here every year, so Canton has a mild winter by US standards; the cooling side runs to 1483 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 12.9°F here (record low 5.5°F), which works out to a seasonal COP of 3.01 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Canton — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, CHEROKEE COUNTY AIRPORT, 6.4 miles from Canton.
The month-to-month numbers for Canton
A 2000-square-foot house here would pull roughly 2,373 heating kilowatt-hours annually on top of cooling, totalling about $542 a year on electricity. That compares with roughly 29 Mcf a year of gas at Canton's 20.42 per-Mcf rate — about $886 a year — against a local electricity rate of 14.90¢/kWh. Buy it outright, not incrementally, and payback stretches to 39.2 years; over 15 years the net position sits $1,665 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Canton heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $809 a year, which recovers the extra $8,000 spent going electric in roughly 9.9 years.
Where Canton ranks in this dataset
Ranked against the other 3206 cities covered, Canton comes in at 1984 for heating severity — 1 would be the coldest place in the dataset — and 1091 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Canton's 3.01 seasonal COP and payback figure. Canton's 12.9°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.
