Heat Pump Payback in Leland, NC
Should Leland switch to a heat pump?
Leland technically pencils out, but only past the point the equipment would need replacing anyway. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Leland's residents would see roughly $245 a year back in running costs, putting the payback around 22.5 years. Leland's own numbers say this pencils out only in theory, not in practice.

Why Leland's climate drives this number
Leland has a mild winter by US standards, 1904 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 2173 cooling degree days. 21°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 19°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.2 on the cold-climate unit fit for this climate. The average winter here is gentle, but sizing follows the cold snaps, and 21°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Leland. These numbers come from Wilmington International Airp, the closest NOAA station, 9 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,507 kWh a year to keep it warm, plus cooling, for a combined electric bill near $502 a year. Leland's gas rate of $16.42 per Mcf, applied to the 20 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $746 a year, against 14.93¢ per kWh for electricity. Priced as a standalone purchase, with a working furnace ripped out early, payback would take longer than the 15-year equipment life. Measured against the like-for-like replacement instead, a household here ends 15 years $1,832 behind.
What would change Leland's answer
This result holds unless electricity climbs above 59.9¢/kWh (it is 14.93¢ now) or gas drops below $4.09 per Mcf (now $16.42); past either point, gas becomes the cheaper fuel in Leland. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $245 a year saved, a difference under $1,715 pays back within 7 years here, and under $2,450 within 10.
The other scenario: no gas furnace to begin with
Plenty of homes in Leland heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Leland's answer improves. Even against resistance heat, the running-cost gap here isn't enough to clear the $10,000 incremental cost within the equipment's 15-year life.
How Leland compares nationally
Among 3206 cities, Leland's winter puts it at rank 2481 for severity, while its size puts it at rank 1194 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.
