Fayetteville, AR: the heat pump payback math
Fayetteville sits right on the fence — how long you'll own the house decides this one. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $340 of lower running costs every year, landing the payback clock at roughly 10.3 years. Whether that's worth it in Fayetteville depends on how many years you expect to own the place.
Why Fayetteville's climate drives this number
Degree days tell the story here: Fayetteville racks up 3026 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1825 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 1°F, against a record low of -9.9°F. That puts the seasonal coefficient of performance at 2.72 for the recommended cold-climate unit. A cold-climate unit is the right call in Fayetteville — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,817 kWh a year to keep it warm, plus cooling, for a combined electric bill near $581 a year. That compares with roughly 32 Mcf a year of gas at Fayetteville's 19.25 per-Mcf rate — about $921 a year — against a local electricity rate of 13.28¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 39.7 years, leaving the 15-year total $1,600 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Fayetteville — 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. Switching saves about $751 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 10.7 years.
Where Fayetteville ranks in this dataset
Among 3206 cities, Fayetteville's winter puts it at rank 1909 for severity, while its size puts it at rank 324 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 Fayetteville, AR
About 103,134 people live in Fayetteville, Arkansas, 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 2.72 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Fayetteville's 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.
