Will a heat pump pay off in Wilson, NC?
This one's marginal in Wilson: it only clears if you stay long enough. $3,500 is what Wilson would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Wilson's residents would see roughly $251 a year back in running costs, putting the payback around 13.9 years. Whether that's worth it in Wilson depends on how many years you expect to own the place.
The climate behind Wilson's payback figure
Degree days tell the story here: Wilson racks up 2633 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1801 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 18°F, against a record low of 17.1°F. That puts the seasonal coefficient of performance at 3.13 for the recommended cold-climate unit. Wilson 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.

Wilson's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,130 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $547 a year. The gas furnace it replaces burns roughly 27 Mcf a year at 16.42 per Mcf here, for a running cost near $799 a year (electricity here runs 14.93¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 53.7 years, leaving the 15-year total $272 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Wilson heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $797 a year, which recovers the extra $8,000 spent going electric in roughly 10 years.
Where Wilson ranks in this dataset
Wilson lands at position 2076 out of 3206 cities on heating severity (coldest is 1), and 848 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Wilson
About 48,579 people live in Wilson, North Carolina, 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 Wilson's figure comes from
Every constant behind this page — the 3.13 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Wilson's 18°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
