Jacksonville, AR: the heat pump payback math
Jacksonville sits right on the fence — how long you'll own the house decides this one. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Jacksonville's residents would see roughly $359 a year back in running costs, putting the payback around 9.8 years. It's a genuine toss-up here — Jacksonville's numbers don't point clearly either way.
Jacksonville's weather, in the numbers that matter
2606 heating degree days pile up here every year, so Jacksonville has a mild winter by US standards; the cooling side runs to 2216 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 11.8°F, against a record low of -2.6°F. That puts the seasonal coefficient of performance at 2.98 for the recommended cold-climate unit. A cold-climate unit is the right call in Jacksonville — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 2,214 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $545 a year. That compares with roughly 27 Mcf a year of gas at Jacksonville's 19.25 per-Mcf rate — about $904 a year — against a local electricity rate of 13.28¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 37.6 years, for a 15-year net position $1,883 ahead.
Electric resistance heat in Jacksonville, compared
Gas isn't universal in Jacksonville — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $713 a year comes back this way, enough that the 11.2-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Jacksonville ranks in this dataset
Among 3206 cities, Jacksonville's winter puts it at rank 2096 for severity, while its size puts it at rank 1379 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
