Heat Pump Payback in Loganville, GA
Heat pump vs. gas furnace in Loganville, GA
Loganville technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Loganville would pay extra to go electric rather than replace the furnace and AC with the same again. Loganville's residents would see roughly $331 a year back in running costs, putting the payback around 16.6 years. Loganville's own numbers say this pencils out only in theory, not in practice.

Why Loganville's climate drives this number
Degree days tell the story here: Loganville racks up 2526 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1755 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 10.9°F here (coldest 2024 reading 10.9°F), which works out to a seasonal COP of 2.96 for the cold-climate class of unit this climate calls for. The average winter here is gentle, but sizing follows the cold snaps, and 10.9°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 Loganville. These numbers come from Gwinnett Co-Briscoe Fd Apt, the closest NOAA station, 11.1 miles out.
The yearly running costs in Loganville
Electricity use for heating alone comes out to about 2,161 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $545 a year. Loganville's gas rate of $20.42 per Mcf, applied to the 26 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $876 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 $532 behind.
How sensitive Loganville's result is to prices
This result holds unless electricity climbs above 38.8¢/kWh (it is 14.90¢ now) or gas drops below $7.83 per Mcf (now $20.42); past either point, gas becomes the cheaper fuel in Loganville. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $331 a year saved, a difference under $2,317 pays back within 7 years here, and under $3,310 within 10.
Electric resistance heat in Loganville, compared
Not every home in Loganville has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. About $747 a year comes back this way, enough that the 13.4-year payback clears the $10,000 premium comfortably within the equipment's life.
How Loganville compares nationally
Loganville lands at position 2159 out of 3206 cities on heating severity (coldest is 1), and 2208 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.
