Heat Pump Payback in Broken Arrow, OK
Broken Arrow, OK: the heat pump payback math
In Broken Arrow, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Broken Arrow would pay extra to go electric rather than replace the furnace and AC with the same again. Broken Arrow's residents would see roughly $218 a year back in running costs, putting the payback around 25.3 years. Broken Arrow's own numbers say this pencils out only in theory, not in practice.

Why Broken Arrow's climate drives this number
Broken Arrow has a mild winter by US standards, 2849 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 2308 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 6.1°F, and the coldest daily reading in the 2024 station record was -0.9°F. That puts the seasonal coefficient of performance at 2.85 for the recommended cold-climate unit. 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 Broken Arrow.

The yearly running costs in Broken Arrow
A 2000-square-foot house here would pull roughly 2,531 heating kilowatt-hours annually on top of cooling, totalling about $589 a year on electricity. Broken Arrow'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. 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 $2,237 behind.
How sensitive Broken Arrow's result is to prices
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 Broken Arrow. 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.
The other scenario: no gas furnace to begin with
Gas isn't universal in Broken Arrow, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. 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.
