Havelock, NC: the heat pump payback math
Havelock sits right on the fence — how long you'll own the house decides this one. 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). Havelock's residents would see roughly $237 a year back in running costs, putting the payback around 14.8 years. It's a genuine toss-up here — Havelock's numbers don't point clearly either way.
How cold Havelock actually gets
Degree days tell the story here: Havelock racks up 2181 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1881 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 19°F, against a record low of 18°F. That puts the seasonal coefficient of performance at 3.16 for the recommended cold-climate unit. Havelock 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 CHERRY POINT MCAS, the closest NOAA station, 1.1 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 1,748 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $500 a year. That compares with roughly 23 Mcf a year of gas at Havelock's 16.42 per-Mcf rate — about $737 a year — against a local electricity rate of 14.93¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 57.1 years, for a 15-year net position $48 ahead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Havelock 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 $688 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 11.6 years.
How Havelock compares nationally
Among 3206 cities, Havelock's winter puts it at rank 2340 for severity, while its size puts it at rank 2150 for population — 1 in both cases being the extreme. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
What to do with this number in Havelock
Havelock, North Carolina is home to about 17,407 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Havelock, nothing is lost by holding off until the current equipment genuinely fails.

The methodology guide walks through exactly how Havelock's 3.16 seasonal COP and the rest of this page's numbers get built. Havelock's 19°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.
