Heat Pump Payback in Goose Creek, SC
Is a heat pump worth it in Goose Creek?
In Goose Creek, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Goose Creek's residents would see roughly $258 a year back in running costs, putting the payback around 21.3 years. That's a technicality, not a recommendation, for anyone actually living in Goose Creek.

Goose Creek's weather, in the numbers that matter
Goose Creek barely has a winter to speak of, 1497 heating degree days a year against a 65°F base, and summers are severe enough that cooling can dominate the annual bill, at 2554 cooling degree days. Sizing runs off the design temperature, not the average day: 23°F here (coldest 2024 reading 21.9°F), which works out to a seasonal COP of 3.25 for the cold-climate class of unit this climate calls for. Mild on average, but the occasional cold snap is what sizes the equipment: at a 23°F design temperature Goose Creek falls just under the 25°F line where a standard heat pump starts leaning on resistance backup, so the model prices a cold-climate unit to be safe. These numbers come from Charleston Afb/International, the closest NOAA station, 6.9 miles out.
The yearly running costs in Goose Creek
A 2000-square-foot house here would pull roughly 1,166 heating kilowatt-hours annually on top of cooling, totalling about $540 a year on electricity. The gas furnace it replaces burns roughly 16 Mcf a year at $16.91 per Mcf here, for a running cost near $799 a year including the old AC (electricity here runs 16.16¢/kWh). 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 $1,628 behind.
The break-even point in Goose Creek
Gas would only overtake the heat pump in Goose Creek if electricity rose past 775.9¢/kWh from 16.16¢, or gas fell under $0.35 per Mcf from $16.91. A useful quote test for Goose Creek: the heat pump is worth it within a decade if it costs less than $2,580 more than replacing the furnace and AC, and within 7 years if the gap is under $1,806.
Electric resistance heat in Goose Creek, compared
Gas isn't universal in Goose Creek, many houses run on electric heat already. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The gap still doesn't close: the $10,000 incremental cost outlasts the 15-year equipment life here even against resistance heat.
Where Goose Creek ranks in this dataset
Goose Creek lands at position 2694 out of 3206 cities on heating severity (coldest is 1), and 812 out of 3206 by population size (biggest is 1). That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
