Heat Pump Payback in Norcross, GA
Will a heat pump pay off in Norcross, GA?
The payback math works in Norcross on paper, past the equipment's own working life. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Lower bills claw that back: about $344 saved annually, for a payback of roughly 16 years. Norcross's own numbers say this pencils out only in theory, not in practice.

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 (coldest 2024 reading 10.9°F), which works out to a seasonal COP of 2.99 for the cold-climate class of unit this climate calls for. The average winter here is gentle, but sizing follows the cold snaps, and 12°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 Norcross. These numbers come from Dekalb-Peachtree Airport, the closest NOAA station, 7 miles out.
The yearly running costs in 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 the current furnace-and-AC running cost near $903 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 $338 behind.
How sensitive Norcross's result is to prices
This result holds unless electricity climbs above 40.3¢/kWh (it is 14.90¢ now) or gas drops below $7.56 per Mcf (now $20.42); past either point, gas becomes the cheaper fuel in Norcross. 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
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 $10,000 spent up front comes back in about 13 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.

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.
