Heat pump vs. gas furnace in Peachtree Corners, GA

In Peachtree Corners, 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. That premium is recovered through $344 of lower running costs every year, landing the payback clock at roughly 10.2 years. It's a genuine toss-up here — Peachtree Corners's numbers don't point clearly either way.

How cold Peachtree Corners actually gets

2569 heating degree days pile up here every year, so Peachtree Corners has a mild winter by US standards; the cooling side runs to 1846 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°F, against a record low of 10.9°F. That puts the seasonal coefficient of performance at 2.99 for the recommended cold-climate unit. Peachtree Corners 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 DEKALB-PEACHTREE AIRPORT, the closest NOAA station, 7.5 miles out.

Peachtree Corners's running-cost comparison, in dollars

Modelled on a typical 2000-square-foot house, the heat pump draws about 2,176 kWh a year to keep it warm, plus cooling, for a combined electric bill near $559 a year. Peachtree Corners's gas rate of 20.42 per Mcf, applied to the 27 Mcf a year the furnace burns, puts its running cost near $903 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 $1,662 ahead.

Electric resistance heat in Peachtree Corners, compared

Not every home in Peachtree Corners has gas service. Swap the comparison to resistance heat instead of gas, and Peachtree Corners's answer improves. The saving here runs about $767 a year, which recovers the extra $8,000 spent going electric in roughly 10.4 years.
