Will a heat pump pay off in Rocky Mount, NC?
In Rocky Mount, the math is close enough that it comes down to how long you plan to stay. 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 $251 of lower running costs every year, landing the payback clock at roughly 13.9 years. Whether that's worth it in Rocky Mount depends on how many years you expect to own the place.
Why Rocky Mount's climate drives this number
Degree days tell the story here: Rocky Mount 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. 18°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 17.1°F on file. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. Rocky Mount 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. Climate figures trace to the nearest NOAA station, ROCKY MOUNT-WILSON RGN APT, 9.2 miles from Rocky Mount.
What it actually costs to run, year to year
A 2000-square-foot house here would pull roughly 2,130 heating kilowatt-hours annually on top of cooling, totalling about $547 a year on electricity. Rocky Mount's gas rate of 16.42 per Mcf, applied to the 27 Mcf a year the furnace burns, puts its running cost near $799 a year, against 14.93¢ per kWh for electricity. 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.
Electric resistance heat in Rocky Mount, compared
Plenty of homes in Rocky Mount heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Rocky Mount's answer improves. Switching saves about $797 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 years.
Rocky Mount against the rest of the country
Rocky Mount lands at position 2075 out of 3206 cities on heating severity (coldest is 1), and 750 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Rocky Mount's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Rocky Mount's 3.13 seasonal COP and payback figure. At a 18°F design temperature, Rocky Mount sits in cold-climate territory; the guide to that class of unit explains why.
