Heat Pump Payback in Fairmont, WV
Heat pump vs. gas furnace in Fairmont, WV
The payback math works in Fairmont on paper, past the equipment's own working life. $5,500 is what Fairmont would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $129 of lower running costs every year, landing the payback clock at roughly 42.7 years. Fairmont's own numbers say this pencils out only in theory, not in practice.

Why Fairmont's climate drives this number
Degree days tell the story here: Fairmont racks up 4079 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1097 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 12°F, and the coldest daily reading in the 2024 station record was 3°F. That puts the seasonal coefficient of performance at 2.99 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Fairmont sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Harrison/Marion Regional Airport, 13.2 miles from Fairmont.
The yearly running costs in Fairmont
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,454 kWh a year to keep it warm, plus cooling, for a combined electric bill near $676 a year. Fairmont's gas rate of $13.80 per Mcf, applied to the 42 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $805 a year, against 15.41¢ per kWh for electricity. 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 $3,567 behind.
What would change Fairmont's answer
This result holds unless electricity climbs above 19.8¢/kWh (it is 15.41¢ now) or gas drops below $10.77 per Mcf (now $13.80); past either point, gas becomes the cheaper fuel in Fairmont. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $129 a year saved, a difference under $903 pays back within 7 years here, and under $1,290 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Fairmont heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Fairmont's answer improves. About $1,134 a year comes back this way, enough that the 8.8-year payback clears the $10,000 premium comfortably within the equipment's life.
How Fairmont compares nationally
Fairmont lands at position 1471 out of 3206 cities on heating severity (coldest is 1), and 2090 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Every constant behind this page, the 2.99 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Fairmont'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.
