Heat Pump Payback in Ruston, LA
Heat pump vs. gas furnace in Ruston, LA
In Ruston, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. That premium is recovered through $292 of lower running costs every year, landing the payback clock at roughly 18.8 years. That's a technicality, not a recommendation, for anyone actually living in Ruston.

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 low of 12°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.16 on the cold-climate unit fit for this climate. Mild on average, but the occasional cold snap is what sizes the equipment: at a 19°F design temperature Ruston falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe. 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 including the old AC (electricity here runs 13.52¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,119 behind.
How sensitive Ruston's result is to prices
Gas would only overtake the heat pump in Ruston if electricity rose past 465.5¢/kWh from 13.52¢, or gas fell under $0.50 per Mcf from $17.38. A useful quote test for Ruston: the heat pump is worth it within a decade if it costs less than $2,920 more than replacing the furnace and AC, and within 7 years if the gap is under $2,044.
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 gap still doesn't close: the $10,000 incremental cost outlasts the 15-year equipment life here even against resistance heat.
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.

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.
