Heat Pump Payback in Altus, OK
Heat pump vs. gas furnace in Altus, OK
The payback math works in Altus on paper, past the equipment's own working life. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. That premium is recovered through $258 of lower running costs every year, landing the payback clock at roughly 21.3 years. Altus's own numbers say this pencils out only in theory, not in practice.

Why Altus's climate drives this number
Altus has a mild winter by US standards, 2710 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 2849 cooling degree days. 11.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 6.1°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.97 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 11.1°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 Altus. Climate figures trace to the nearest NOAA station, Altus AFB Airport, 2.4 miles from Altus.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 2,310 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $621 a year. That compares with roughly 28 Mcf a year of gas at Altus's $13.99 per-Mcf rate, about $879 a year with the old AC included, against a local electricity rate of 13.10¢/kWh. 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 $1,635 behind.
How sensitive Altus's result is to prices
This result holds unless electricity climbs above 37.7¢/kWh (it is 13.10¢ now) or gas drops below $4.86 per Mcf (now $13.99); past either point, gas becomes the cheaper fuel in Altus. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $258 a year saved, a difference under $1,806 pays back within 7 years here, and under $2,580 within 10.
The other scenario: no gas furnace to begin with
Gas isn't universal in Altus, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Altus's answer improves. Switching saves about $762 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 13.1 years.
Where Altus ranks in this dataset
Among 3206 cities, Altus's winter puts it at rank 2033 for severity, while its size puts it at rank 2047 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
Deciding what's next in Altus, OK
About 18,543 people live in Altus, 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.
Ask a local HVAC contractor for a quote before committing either way.
Where Altus's figure comes from
The methodology guide walks through exactly how Altus's 2.97 seasonal COP and the rest of this page's numbers get built. Altus's 11.1°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.
