Heat pump vs. gas furnace in Ruston, LA
In Ruston, the math is close enough that it comes down to how long you plan to stay. 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 $292 of lower running costs every year, landing the payback clock at roughly 12 years. It's a genuine toss-up here — Ruston's numbers don't point clearly either way.
Ruston's weather, in the numbers that matter
Degree days tell the story here: Ruston racks up 1662 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2858 cooling degree days on the cooling side. 19°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 12°F on file. Worked through the model, that's a seasonal COP of 3.16 on the cold-climate unit fit for this climate. Ruston 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. These numbers come from MONROE REGIONAL AIRPORT, the closest NOAA station, 34.6 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,332 kWh a year to keep it warm, plus cooling, for a combined electric bill near $510 a year. The gas furnace it replaces burns roughly 17 Mcf a year at 17.38 per Mcf here, for a running cost near $802 a year (electricity here runs 13.52¢/kWh). Buy it outright, not incrementally, and payback stretches to 46.2 years; over 15 years the net position sits $881 ahead.
Electric resistance heat in Ruston, compared
Gas isn't universal in Ruston — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Ruston's answer improves. The saving here runs about $560 a year, which recovers the extra $8,000 spent going electric in roughly 14.3 years.
Ruston against the rest of the country
Among 3206 cities, Ruston's winter puts it at rank 2618 for severity, while its size puts it at rank 1761 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.
Deciding what's next in Ruston, LA
Ruston, Louisiana is home to about 22,330 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 Ruston, nothing is lost by holding off until the current equipment genuinely fails.

Where Ruston's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Ruston's 3.16 seasonal COP and payback figure. Ruston's 19°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.
