The window here is reasonable, and it's specific to what Holly Hill actually pays for power and gas.
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 record low of 36°F on file. 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 its running cost near $837 a year, against 15.43¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 34.3 years; over 15 years the net position sits $3,815 ahead.
