Should Jackson switch to a heat pump?
In Jackson, 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). Lower bills claw that back: about $273 saved annually, for a payback of roughly 12.8 years. Whether that's worth it in Jackson depends on how many years you expect to own the place.
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 record low of 10°F on file. Worked through the model, that's a seasonal COP of 3.18 on the cold-climate unit fit for this climate. Jackson 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. 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 its running cost near $844 a year, against 15.47¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 49.5 years; over 15 years the net position sits $588 ahead.
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. The saving here runs about $658 a year, which recovers the extra $8,000 spent going electric in roughly 12.2 years.
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.

About 141,449 people live in Jackson, Mississippi, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

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.
