Will a heat pump pay off in Fort Smith, AR?
Fort Smith 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 $358 of lower running costs every year, landing the payback clock at roughly 9.8 years. It's a genuine toss-up here — Fort Smith's numbers don't point clearly either way.
Fort Smith's weather, in the numbers that matter
2457 heating degree days pile up here every year, so Fort Smith has a mild winter by US standards; the cooling side runs to 2568 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 8.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 3°F on file. Worked through the model, that's a seasonal COP of 2.89 on the cold-climate unit fit for this climate. Fort Smith 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.

Fort Smith's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,153 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $577 a year. Fort Smith's gas rate of 19.25 per Mcf, applied to the 26 Mcf a year the furnace burns, puts its running cost near $935 a year, against 13.28¢ per kWh for electricity. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 37.7 years, for a 15-year net position $1,869 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Fort Smith — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Fort Smith's answer improves. The saving here runs about $692 a year, which recovers the extra $8,000 spent going electric in roughly 11.6 years.
Where Fort Smith ranks in this dataset
Fort Smith lands at position 2201 out of 3206 cities on heating severity (coldest is 1), and 391 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
Deciding what's next in Fort Smith, AR
Fort Smith, Arkansas is home to about 90,507 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Fort Smith, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
Where Fort Smith's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Fort Smith's 2.89 seasonal COP and payback figure. At a 8.1°F design temperature, Fort Smith sits in cold-climate territory; the guide to that class of unit explains why.
