Heat Pump Payback in Lawton, OK
Is a heat pump worth it in Lawton?
Lawton technically pencils out, but only past the point the equipment would need replacing anyway. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Lawton's residents would see roughly $240 a year back in running costs, putting the payback around 22.9 years. Lawton's own numbers say this pencils out only in theory, not in practice.

Why Lawton's climate drives this number
Degree days tell the story here: Lawton racks up 1964 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2793 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 17.8°F here (coldest 2024 reading 6.8°F), which works out to a seasonal COP of 3.13 for the cold-climate class of unit this climate calls for. The average winter here is gentle, but sizing follows the cold snaps, and 17.8°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 Lawton. Climate figures trace to the nearest NOAA station, Henry Post Aaf Airport, 2.6 miles from Lawton.
The yearly running costs in Lawton
A 2000-square-foot house here would pull roughly 1,589 heating kilowatt-hours annually on top of cooling, totalling about $520 a year on electricity. The gas furnace it replaces burns roughly 20 Mcf a year at $13.99 per Mcf here, for a running cost near $760 a year including the old AC (electricity here runs 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 $1,896 behind.
The break-even point in Lawton
This result holds unless electricity climbs above 81.6¢/kWh (it is 13.10¢ now) or gas drops below $2.24 per Mcf (now $13.99); past either point, gas becomes the cheaper fuel in Lawton. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $240 a year saved, a difference under $1,680 pays back within 7 years here, and under $2,400 within 10.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Lawton, 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. Even against resistance heat, the running-cost gap here isn't enough to clear the $10,000 incremental cost within the equipment's 15-year life.
How Lawton compares nationally
Among 3206 cities, Lawton's winter puts it at rank 2439 for severity, while its size puts it at rank 394 for population, 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
What to do with this number in Lawton
About 90,027 people live in Lawton, 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 Lawton's figure comes from
Every constant behind this page, the 3.13 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Lawton's 17.8°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
