Heat Pump Payback in Guymon, OK
Is a heat pump worth it in Guymon?
In Guymon, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Guymon would pay extra to go electric rather than replace the furnace and AC with the same again. Guymon's residents would see roughly $194 a year back in running costs, putting the payback around 28.3 years. Guymon's own numbers say this pencils out only in theory, not in practice.

The climate behind Guymon's payback figure
3931 heating degree days pile up here every year, so Guymon has a real but manageable winter; the cooling side runs to 1646 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 1.9°F, and the coldest daily reading in the 2024 station record was -0.9°F. That puts the seasonal coefficient of performance at 2.75 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Guymon sits firmly in cold-climate territory, so that's the class of unit priced here.

The yearly running costs in Guymon
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,620 kWh a year to keep it warm, plus cooling, for a combined electric bill near $658 a year. That compares with roughly 41 Mcf a year of gas at Guymon's $13.99 per-Mcf rate, about $852 a year with the old AC included, against a local electricity rate of 13.10¢/kWh. 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 $2,587 behind.
How sensitive Guymon's result is to prices
This result holds unless electricity climbs above 19.8¢/kWh (it is 13.10¢ now) or gas drops below $9.25 per Mcf (now $13.99); past either point, gas becomes the cheaper fuel in Guymon. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $194 a year saved, a difference under $1,358 pays back within 7 years here, and under $1,940 within 10.
Electric resistance heat in Guymon, compared
Plenty of homes in Guymon heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Guymon's answer improves. Switching saves about $925 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 10.8 years.
Guymon against the rest of the country
Among 3206 cities, Guymon's winter puts it at rank 1562 for severity, while its size puts it at rank 2747 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
