Heat Pump Payback in Jackson, MS
Should Jackson switch to a heat pump?
In Jackson, 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. Lower bills claw that back: about $273 saved annually, for a payback of roughly 20.2 years. Jackson's own numbers say this pencils out only in theory, not in practice.

Why Jackson's climate drives this number
1765 heating degree days pile up here every year, so Jackson has a mild winter by US standards; the cooling side runs to 2684 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 19.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 10°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.18 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 19.9°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 Jackson. Climate figures trace to the nearest NOAA station, Hawkins Field Airport, 1.5 miles from Jackson.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,405 heating kilowatt-hours annually on top of cooling, totalling about $571 a year on electricity. Jackson's gas rate of $16.64 per Mcf, applied to the 18 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $844 a year, against 15.47¢ per kWh for electricity. 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 $1,412 behind.
What would change Jackson's answer
This result holds unless electricity climbs above 142.0¢/kWh (it is 15.47¢ now) or gas drops below $1.81 per Mcf (now $16.64); past either point, gas becomes the cheaper fuel in Jackson. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $273 a year saved, a difference under $1,911 pays back within 7 years here, and under $2,730 within 10.
Electric resistance heat in Jackson, compared
Plenty of homes in Jackson heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. 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.
How Jackson compares nationally
Ranked against the other 3206 cities covered, Jackson comes in at 2558 for heating severity, 1 would be the coldest place in the dataset, and 198 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.

Where Jackson's figure comes from
The methodology guide walks through exactly how Jackson's 3.18 seasonal COP and the rest of this page's numbers get built. Jackson's 19.9°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.
