Will a heat pump pay off in Winder, GA?
This one's marginal in Winder: it only clears if you stay long enough. 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. Winder's residents would see roughly $362 a year back in running costs, putting the payback around 9.7 years. Whether that's worth it in Winder depends on how many years you expect to own the place.
The climate behind Winder's payback figure
2648 heating degree days pile up here every year, so Winder has a mild winter by US standards; the cooling side runs to 1666 cooling degree days, where summers are hot enough that cooling matters as much as heating. 21.2°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 12.2°F on file. Worked through the model, that's a seasonal COP of 3.21 on the cold-climate unit fit for this climate. Winder 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. Climate figures trace to the nearest NOAA station, WINDER-BORROW AIRPORT, 3.2 miles from Winder.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 2,089 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $523 a year. That compares with roughly 28 Mcf a year of gas at Winder's 20.42 per-Mcf rate — about $885 a year — against a local electricity rate of 14.90¢/kWh. Buy it outright, not incrementally, and payback stretches to 37.3 years; over 15 years the net position sits $1,930 ahead.
The other scenario: no gas furnace to begin with
Plenty of homes in Winder heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $798 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 10 years.
Winder against the rest of the country
Winder lands at position 2068 out of 3206 cities on heating severity (coldest is 1), and 1877 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Winder's 3.21 seasonal COP and payback figure. Winder's 21.2°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
