Is a heat pump worth it in Milton?
In Milton, the math is close enough that it comes down to how long you plan to stay. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $344 saved annually, for a payback of roughly 10.2 years. Whether that's worth it in Milton depends on how many years you expect to own the place.
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, against a record low of 5.5°F. That puts the seasonal coefficient of performance at 3.01 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Milton sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, CHEROKEE COUNTY AIRPORT, 13.3 miles from Milton.
The month-to-month numbers for 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 its running cost near $886 a year, against 14.90¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 39.2 years; over 15 years the net position sits $1,665 ahead.
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 $8,000 spent going electric in roughly 9.9 years.

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.
