Chestnut Ridge, NY: the heat pump payback math
Here in Chestnut Ridge, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). The heat pump would cost about $94 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Chestnut Ridge's numbers say wait.
The climate behind Chestnut Ridge's payback figure
4363 heating degree days pile up here every year, so Chestnut Ridge has a real but manageable winter; the cooling side runs to 1248 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 15.1°F, against a record low of 9°F. That puts the seasonal coefficient of performance at 3.06 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Chestnut Ridge sits firmly in cold-climate territory, so that's the class of unit priced here.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,610 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,366 a year. That compares with roughly 45 Mcf a year of gas at Chestnut Ridge's 17.58 per-Mcf rate — about $1,271 a year — against a local electricity rate of 29.22¢/kWh. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $4,917 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Chestnut Ridge heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. The saving here runs about $2,335 a year, which recovers the extra $8,000 spent going electric in roughly 3.4 years.
