Will a heat pump pay off in Bethany, OK?
This one's marginal in Bethany: it only clears if you stay long enough. $3,500 is what Bethany would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Lower bills claw that back: about $236 saved annually, for a payback of roughly 14.8 years. Whether that's worth it in Bethany depends on how many years you expect to own the place.
The climate behind Bethany's payback figure
2841 heating degree days pile up here every year, so Bethany has a mild winter by US standards; the cooling side runs to 2494 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 9°F, against a record low of 0°F. That puts the seasonal coefficient of performance at 2.92 for the recommended cold-climate unit. Bethany needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from WILEY POST AIRPORT, the closest NOAA station, 1.9 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,464 kWh a year to keep it warm, plus cooling, for a combined electric bill near $601 a year. The gas furnace it replaces burns roughly 30 Mcf a year at 13.99 per Mcf here, for a running cost near $837 a year (electricity here runs 13.10¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 57.2 years, for a 15-year net position $41 ahead.
The other scenario: no gas furnace to begin with
Not every home in Bethany has gas service. 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 $765 a year, which recovers the extra $8,000 spent going electric in roughly 10.5 years.
How Bethany compares nationally
Among 3206 cities, Bethany's winter puts it at rank 1976 for severity, while its size puts it at rank 1886 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
Next step for 20,421 people in Bethany
About 20,421 people live in Bethany, Oklahoma, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

More on how this number was built
Every constant behind this page — the 2.92 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a 9°F design temperature, Bethany sits in cold-climate territory; the guide to that class of unit explains why.
