Heat Pump Payback in Fairfield, OH
Is a heat pump worth it in Fairfield?
Fairfield technically pencils out, but only past the point the equipment would need replacing anyway. $5,500 is what Fairfield would pay extra to go electric rather than replace the furnace and AC with the same again. Lower bills claw that back: about $26 saved annually, for a payback of roughly 207.9 years. Fairfield's own numbers say this pencils out only in theory, not in practice.

The climate behind Fairfield's payback figure
Degree days tell the story here: Fairfield racks up 3982 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1348 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 5°F, and the coldest daily reading in the 2024 station record was -2.9°F. That puts the seasonal coefficient of performance at 2.82 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Fairfield sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Butler Co. Regional Airport, 2.4 miles from Fairfield.
Fairfield's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 3,576 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $869 a year. Fairfield's gas rate of $13.85 per Mcf, applied to the 41 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $896 a year, against 18.40¢ per kWh for electricity. 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 $5,103 behind.
What would change Fairfield's answer
This result holds unless electricity climbs above 19.3¢/kWh (it is 18.40¢ now) or gas drops below $13.21 per Mcf (now $13.85); past either point, gas becomes the cheaper fuel in Fairfield. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $26 a year saved, a difference under $182 pays back within 7 years here, and under $260 within 10.
The other scenario: no gas furnace to begin with
Gas isn't universal in Fairfield, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,307 a year, which recovers the extra $10,000 spent going electric in roughly 7.6 years.
