Heat Pump Payback in Fayetteville, GA
Will a heat pump pay off in Fayetteville, GA?
In Fayetteville, the extra upfront cost technically comes back, just not before the equipment wears out. 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. That's a technicality, not a recommendation, for anyone actually living in Fayetteville.

Fayetteville's weather, in the numbers that matter
Degree days tell the story here: Fayetteville racks up 2462 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1947 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 12.9°F here (coldest 2024 reading 12°F), which works out to a seasonal COP of 3.01 for the cold-climate class of unit this climate calls for. Mild on average, but the occasional cold snap is what sizes the equipment: at a 12.9°F design temperature Fayetteville falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe. These numbers come from Pchtre Cty-Falcon Fld Airport, the closest NOAA station, 8.5 miles out.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 2,071 heating kilowatt-hours annually on top of cooling, totalling about $556 a year on electricity. That compares with roughly 26 Mcf a year of gas at Fayetteville's $20.42 per-Mcf rate, about $900 a year with the old AC included, against a local electricity rate of 14.90¢/kWh. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $346 behind.
What would change Fayetteville's answer
Gas would only overtake the heat pump in Fayetteville if electricity rose past 43.3¢/kWh from 14.90¢, or gas fell under $7.02 per Mcf from $20.42. A useful quote test for Fayetteville: the heat pump is worth it within a decade if it costs less than $3,440 more than replacing the furnace and AC, and within 7 years if the gap is under $2,408.
Electric resistance heat in Fayetteville, compared
Plenty of homes in Fayetteville heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Fayetteville's answer improves. About $749 a year comes back this way, enough that the 13.4-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Fayetteville ranks in this dataset
Ranked against the other 3206 cities covered, Fayetteville comes in at 2197 for heating severity, 1 would be the coldest place in the dataset, and 1887 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

Where Fayetteville'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. Fayetteville's 12.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
