Concord, NC: the heat pump payback math
This one's marginal in Concord: it only clears if you stay long enough. 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. That premium is recovered through $254 of lower running costs every year, landing the payback clock at roughly 13.8 years. Whether that's worth it in Concord depends on how many years you expect to own the place.
Why Concord's climate drives this number
Concord has a mild winter by US standards — 2683 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1734 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 19.4°F, against a record low of 12.2°F. That puts the seasonal coefficient of performance at 3.17 for the recommended cold-climate unit. Concord 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. These numbers come from CONCORD REGIONAL AIRPORT, the closest NOAA station, 4 miles out.
Concord's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 2,143 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $541 a year. The gas furnace it replaces burns roughly 28 Mcf a year at 16.42 per Mcf here, for a running cost near $794 a year (electricity here runs 14.93¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 53.2 years, for a 15-year net position $304 ahead.
Electric resistance heat in Concord, compared
Plenty of homes in Concord 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. Switching saves about $809 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 9.9 years.
Where Concord ranks in this dataset
Among 3206 cities, Concord's winter puts it at rank 2044 for severity, while its size puts it at rank 284 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
What to do with this number in Concord
About 112,395 people live in Concord, 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 Concord's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Concord's 3.17 seasonal COP and payback figure. Concord's 19.4°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
