The climate behind Fort Oglethorpe's payback figure
Fort Oglethorpe has a mild winter by US standards, 2547 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 2181 cooling degree days. 12.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 10.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.01 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 12.9°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 Fort Oglethorpe. These numbers come from Lovell Field Airport, the closest NOAA station, 7.5 miles out.
Fort Oglethorpe's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,143 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $596 a year. The gas furnace it replaces burns roughly 27 Mcf a year at $20.42 per Mcf here, for a running cost near $963 a year including the old AC (electricity here runs 14.90¢/kWh). If the current system still worked and you replaced it anyway, the full cost would take longer than the 15-year equipment life to earn back; against buying a new furnace and AC regardless, the 15-year total lands $3 behind.
How sensitive Fort Oglethorpe's result is to prices
This result holds unless electricity climbs above 46.1¢/kWh (it is 14.90¢ now) or gas drops below $6.60 per Mcf (now $20.42); past either point, gas becomes the cheaper fuel in Fort Oglethorpe. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $366 a year saved, a difference under $2,562 pays back within 7 years here, and under $3,660 within 10.
Electric resistance heat in Fort Oglethorpe, compared
Plenty of homes in Fort Oglethorpe heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Fort Oglethorpe's answer improves. The saving here runs about $786 a year, which recovers the extra $10,000 spent going electric in roughly 12.7 years.

Where Fort Oglethorpe's figure comes from
Every constant behind this page, the 3.01 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Fort Oglethorpe's 12.9°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.
