Heat pump vs. gas furnace in Belmont, NC
In Belmont, 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 $253 saved annually, for a payback of roughly 13.8 years. It's a genuine toss-up here — Belmont's numbers don't point clearly either way.
Belmont's weather, in the numbers that matter
Belmont has a mild winter by US standards — 2436 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1981 cooling degree days. 18°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 12.9°F on file. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Belmont sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 1,971 heating kilowatt-hours annually on top of cooling, totalling about $546 a year on electricity. That compares with roughly 25 Mcf a year of gas at Belmont's 16.42 per-Mcf rate — about $800 a year — against a local electricity rate of 14.93¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 53.3 years, leaving the 15-year total $302 ahead.
The other scenario: no gas furnace to begin with
Not every home in Belmont has gas service. 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 $758 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 10.6 years.
Belmont against the rest of the country
Among 3206 cities, Belmont's winter puts it at rank 2217 for severity, while its size puts it at rank 2291 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.
Next step for 16,044 people in Belmont
Belmont, North Carolina is home to about 16,044 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 Belmont, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Belmont's 3.13 seasonal COP and payback figure. Belmont's 18°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.
