Heat Pump Payback in Peachtree City, GA
Should Peachtree City switch to a heat pump?
Peachtree City technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Peachtree City would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $344 of lower running costs every year, landing the payback clock at roughly 16 years. Peachtree City's own numbers say this pencils out only in theory, not in practice.

Why Peachtree City's climate drives this number
2462 heating degree days pile up here every year, so Peachtree City has a mild winter by US standards; the cooling side runs to 1947 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 12.9°F, and the coldest daily reading in the 2024 station record was 12°F. That puts the seasonal coefficient of performance at 3.01 for the recommended cold-climate unit. The average winter here is gentle, but sizing follows the cold snaps, and 12.9°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Peachtree City.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,071 kWh a year to keep it warm, plus cooling, for a combined electric bill near $556 a year. The gas furnace it replaces burns roughly 26 Mcf a year at $20.42 per Mcf here, for a running cost near $900 a year including the old AC (electricity here runs 14.90¢/kWh). Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $346 behind.
The break-even point in Peachtree City
This result holds unless electricity climbs above 43.3¢/kWh (it is 14.90¢ now) or gas drops below $7.02 per Mcf (now $20.42); past either point, gas becomes the cheaper fuel in Peachtree City. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $344 a year saved, a difference under $2,408 pays back within 7 years here, and under $3,440 within 10.
The other scenario: no gas furnace to begin with
Plenty of homes in Peachtree City 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. About $749 a year comes back this way, enough that the 13.4-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Peachtree City ranks in this dataset
Among 3206 cities, Peachtree City's winter puts it at rank 2196 for severity, while its size puts it at rank 1007 for population, 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Where Peachtree City's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Peachtree City's 3.01 seasonal COP and payback figure. Peachtree City'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.
