Will a heat pump pay off in Norcross, GA?
This one's marginal in Norcross: it only clears if you stay long enough. 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 $344 saved annually, for a payback of roughly 10.2 years. Whether that's worth it in Norcross depends on how many years you expect to own the place.
The climate behind Norcross's payback figure
2569 heating degree days pile up here every year, so Norcross 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. Sizing runs off the design temperature, not the average day: 12°F here (record low 10.9°F), which works out to a seasonal COP of 2.99 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Norcross — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from DEKALB-PEACHTREE AIRPORT, the closest NOAA station, 7 miles out.
The month-to-month numbers for Norcross
A 2000-square-foot house here would pull roughly 2,176 heating kilowatt-hours annually on top of cooling, totalling about $559 a year on electricity. Norcross'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.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Norcross — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $767 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 10.4 years.
Norcross against the rest of the country
Ranked against the other 3206 cities covered, Norcross comes in at 2113 for heating severity — 1 would be the coldest place in the dataset — and 2019 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
Next step for 18,902 people in Norcross
About 18,902 people live in Norcross, Georgia, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

More on how this number was built
The methodology guide walks through exactly how Norcross's 2.99 seasonal COP and the rest of this page's numbers get built. Norcross's 12°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.
