Heat Pump Payback in Laurel, MS
Is a heat pump worth it in Laurel?
In Laurel, the extra upfront cost technically comes back, just not before the equipment wears out. $5,500 is what Laurel would pay extra to go electric rather than replace the furnace and AC with the same again. That premium is recovered through $261 of lower running costs every year, landing the payback clock at roughly 21 years. Laurel's own numbers say this pencils out only in theory, not in practice.

The climate behind Laurel's payback figure
1723 heating degree days pile up here every year, so Laurel has a mild winter by US standards; the cooling side runs to 2532 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. Sizing runs off the design temperature, not the average day: 21°F here (coldest 2024 reading 10.9°F), which works out to a seasonal COP of 3.2 for the cold-climate class of unit this climate calls for. The average winter here is gentle, but sizing follows the cold snaps, and 21°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 Laurel.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,363 kWh a year to keep it warm, plus cooling, for a combined electric bill near $545 a year. That compares with roughly 18 Mcf a year of gas at Laurel's $16.64 per-Mcf rate, about $806 a year with the old AC included, against a local electricity rate of 15.47¢/kWh. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,580 behind.
What would change Laurel's answer
This result holds unless electricity climbs above 124.0¢/kWh (it is 15.47¢ now) or gas drops below $2.08 per Mcf (now $16.64); past either point, gas becomes the cheaper fuel in Laurel. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $261 a year saved, a difference under $1,827 pays back within 7 years here, and under $2,610 within 10.
Electric resistance heat in Laurel, compared
Not every home in Laurel has gas service. 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.
Where Laurel ranks in this dataset
Ranked against the other 3206 cities covered, Laurel comes in at 2578 for heating severity, 1 would be the coldest place in the dataset, and 2138 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.

More on how this number was built
Every constant behind this page, the 3.2 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide. Laurel's 21°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.
