Heat Pump Payback in Coweta, OK
Will a heat pump pay off in Coweta, OK?
In Coweta, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $218 saved annually, for a payback of roughly 25.3 years. Coweta's own numbers say this pencils out only in theory, not in practice.

Why Coweta's climate drives this number
2849 heating degree days pile up here every year, so Coweta has a mild winter by US standards; the cooling side runs to 2308 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 6.1°F here (coldest 2024 reading -0.9°F), which works out to a seasonal COP of 2.85 for the cold-climate class of unit this climate calls for. The average winter here is gentle, but sizing follows the cold snaps, and 6.1°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 Coweta. Climate figures trace to the nearest NOAA station, Richard Lloyd Jones Jr Apt, 18.7 miles from Coweta.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 2,531 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $589 a year. Coweta's gas rate of $13.99 per Mcf, applied to the 30 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $807 a year, against 13.10¢ 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 $2,237 behind.
The break-even point in Coweta
This result holds unless electricity climbs above 27.5¢/kWh (it is 13.10¢ now) or gas drops below $6.66 per Mcf (now $13.99); past either point, gas becomes the cheaper fuel in Coweta. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $218 a year saved, a difference under $1,526 pays back within 7 years here, and under $2,180 within 10.
If your home heats with electric baseboard instead of gas
Plenty of homes in Coweta heat with electricity alone, no gas line involved. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. Switching saves about $747 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 13.4 years.
Where Coweta ranks in this dataset
Ranked against the other 3206 cities covered, Coweta comes in at 1971 for heating severity, 1 would be the coldest place in the dataset, and 2972 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
