Holly Hill's weather, in the numbers that matter
606 heating degree days pile up here every year, so Holly Hill barely has a winter to speak of; the cooling side runs to 3381 cooling degree days, where summers are severe enough that cooling can dominate the annual bill. 37.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 36°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.33 on the standard unit fit for this climate. Holly Hill's winters don't get cold enough to need the cold-climate premium, a standard unit holds up fine.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 461 kWh a year to keep it warm, plus cooling, for a combined electric bill near $516 a year. Holly Hill's gas rate of $25.48 per Mcf, applied to the 6 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $837 a year, against 15.43¢ per kWh for electricity. Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,815 ahead.
What would change Holly Hill's answer
In Holly Hill the cooling savings outweigh the extra electricity for heating, so no plausible change in the electricity rate would make the old furnace and AC cheaper to run. A useful quote test for Holly Hill: the heat pump is worth it within a decade if it costs less than $3,210 more than replacing the furnace and AC, and within 7 years if the gap is under $2,247.
Electric resistance heat in Holly Hill, compared
