Will a heat pump pay off in Fort Oglethorpe, GA?

In Fort Oglethorpe, the math is close enough that it comes down to how long you plan to stay. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Fort Oglethorpe's residents would see roughly $366 a year back in running costs, putting the payback around 9.6 years. Whether that's worth it in Fort Oglethorpe depends on how many years you expect to own the place.

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 record low of 10.9°F on file. Worked through the model, that's a seasonal COP of 3.01 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Fort Oglethorpe — 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 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 (electricity here runs 14.90¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 36.8 years, leaving the 15-year total $1,997 ahead.

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 $8,000 spent going electric in roughly 10.2 years.

Fort Oglethorpe against the rest of the country

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.
