Will a heat pump pay off in Newnan, GA?
In Newnan, the math is close enough that it comes down to how long you plan to stay. 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. Lower bills claw that back: about $326 saved annually, for a payback of roughly 10.7 years. Whether that's worth it in Newnan depends on how many years you expect to own the place.
Why Newnan's climate drives this number
2198 heating degree days pile up here every year, so Newnan has a mild winter by US standards; the cooling side runs to 1847 cooling degree days, where summers are hot enough that cooling matters as much as heating. 18.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 13.1°F on file. Worked through the model, that's a seasonal COP of 3.15 on the cold-climate unit fit for this climate. Newnan 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.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,767 heating kilowatt-hours annually on top of cooling, totalling about $498 a year on electricity. That compares with roughly 23 Mcf a year of gas at Newnan's 20.42 per-Mcf rate — about $824 a year — against a local electricity rate of 14.90¢/kWh. Buy it outright, not incrementally, and payback stretches to 41.4 years; over 15 years the net position sits $1,393 ahead.
Electric resistance heat in Newnan, compared
Gas isn't universal in Newnan — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $688 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 11.6 years.
Newnan against the rest of the country
Newnan lands at position 2326 out of 3206 cities on heating severity (coldest is 1), and 903 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
