Heat Pump Payback in Milton, GA
Is a heat pump worth it in Milton?
In Milton, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $344 saved annually, for a payback of roughly 16 years. Milton's own numbers say this pencils out only in theory, not in practice.

Why Milton's climate drives this number
2821 heating degree days pile up here every year, so Milton 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. 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 5.5°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 Milton. Climate figures trace to the nearest NOAA station, Cherokee County Airport, 13.3 miles from Milton.
The yearly running costs in Milton
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,373 kWh a year to keep it warm, plus cooling, for a combined electric bill near $542 a year. Milton's gas rate of $20.42 per Mcf, applied to the 29 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $886 a year, against 14.90¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $335 behind.
How sensitive Milton's result is to prices
This result holds unless electricity climbs above 35.0¢/kWh (it is 14.90¢ now) or gas drops below $8.70 per Mcf (now $20.42); past either point, gas becomes the cheaper fuel in Milton. 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.
If your home heats with electric baseboard instead of gas
Not every home in Milton has gas service. Swap the comparison to resistance heat instead of gas, and Milton's answer improves. The saving here runs about $809 a year, which recovers the extra $10,000 spent going electric in roughly 12.4 years.
Where Milton ranks in this dataset

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