Heat Pump Payback in Mustang, OK
Should Mustang switch to a heat pump?
In Mustang, 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 $207 saved annually, for a payback of roughly 26.6 years. Mustang's own numbers say this pencils out only in theory, not in practice.

Why Mustang's climate drives this number
Mustang has a mild winter by US standards, 2933 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 2206 cooling degree days. 3.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 1°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.79 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 3.9°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 Mustang. These numbers come from Will Rogers World Airport, the closest NOAA station, 7 miles out.
Mustang's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,662 kWh a year to keep it warm, plus cooling, for a combined electric bill near $595 a year. The gas furnace it replaces burns roughly 31 Mcf a year at $13.99 per Mcf here, for a running cost near $802 a year including the old AC (electricity here runs 13.10¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $2,399 behind.
How sensitive Mustang's result is to prices
This result holds unless electricity climbs above 25.4¢/kWh (it is 13.10¢ now) or gas drops below $7.22 per Mcf (now $13.99); past either point, gas becomes the cheaper fuel in Mustang. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $207 a year saved, a difference under $1,449 pays back within 7 years here, and under $2,070 within 10.
Electric resistance heat in Mustang, compared
Gas isn't universal in Mustang, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $752 a year, which recovers the extra $10,000 spent going electric in roughly 13.3 years.
How Mustang compares nationally
Mustang lands at position 1951 out of 3206 cities on heating severity (coldest is 1), and 1663 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Mustang's figure comes from
Every constant behind this page, the 2.79 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Mustang's 3.9°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.
