Heat pump vs. gas furnace in Covington, GA
This one's marginal in Covington: it only clears if you stay long enough. $3,500 is what Covington 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. That premium is recovered through $348 of lower running costs every year, landing the payback clock at roughly 10.1 years. Whether that's worth it in Covington depends on how many years you expect to own the place.
Why Covington's climate drives this number
2550 heating degree days pile up here every year, so Covington has a mild winter by US standards; the cooling side runs to 1711 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 17.8°F, against a record low of 10.4°F. That puts the seasonal coefficient of performance at 3.13 for the recommended cold-climate unit. Covington 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. These numbers come from MONROE WALTON CO, the closest NOAA station, 15.1 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,063 kWh a year to keep it warm, plus cooling, for a combined electric bill near $525 a year. Covington's gas rate of 20.42 per Mcf, applied to the 27 Mcf a year the furnace burns, puts its running cost near $873 a year, against 14.90¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 38.8 years, for a 15-year net position $1,719 ahead.
If your home heats with electric baseboard instead of gas
Not every home in Covington has gas service. Swap the comparison to resistance heat instead of gas, and Covington's answer improves. Switching saves about $768 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 10.4 years.
Covington against the rest of the country
Among 3206 cities, Covington's winter puts it at rank 2126 for severity, while its size puts it at rank 2362 for population — 1 in both cases being the extreme. 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 Covington's 3.13 seasonal COP and payback figure. Covington's 17.8°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
