Heat pump vs. gas furnace in Salisbury, NC
In Salisbury, 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). Salisbury's residents would see roughly $243 a year back in running costs, putting the payback around 14.4 years. Whether that's worth it in Salisbury depends on how many years you expect to own the place.
Why Salisbury's climate drives this number
Salisbury has a real but manageable winter — 3169 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1328 cooling degree days. Sizing runs off the design temperature, not the average day: 16.5°F here (record low 11.5°F), which works out to a seasonal COP of 3.1 for the cold-climate class of unit this climate calls for. Salisbury 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.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,588 kWh a year to keep it warm, plus cooling, for a combined electric bill near $556 a year. That compares with roughly 33 Mcf a year of gas at Salisbury's 16.42 per-Mcf rate — about $799 a year — against a local electricity rate of 14.93¢/kWh. Buy it outright, not incrementally, and payback stretches to 55.5 years; over 15 years the net position sits $151 ahead.
The other scenario: no gas furnace to begin with
Not every home in Salisbury 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. The saving here runs about $899 a year, which recovers the extra $8,000 spent going electric in roughly 8.9 years.
