Port Chester, NY: the heat pump payback math
Port Chester is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Running costs here land $164 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Port Chester's numbers say wait.
Why Port Chester's climate drives this number
Degree days tell the story here: Port Chester racks up 4760 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 888 cooling degree days on the cooling side. 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 6.1°F. That puts the seasonal coefficient of performance at 3.06 for the recommended cold-climate unit. A cold-climate unit is the right call in Port Chester — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, WESTCHESTER COUNTY AIRPORT, 4.4 miles from Port Chester.
The month-to-month numbers for Port Chester
A 2000-square-foot house here would pull roughly 3,939 heating kilowatt-hours annually on top of cooling, totalling about $1,372 a year on electricity. That compares with roughly 50 Mcf a year of gas at Port Chester's 17.58 per-Mcf rate — about $1,208 a year — against a local electricity rate of 29.22¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $5,966 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Port Chester — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Port Chester's answer improves. The saving here runs about $2,486 a year, which recovers the extra $8,000 spent going electric in roughly 3.2 years.
Where Port Chester ranks in this dataset
Among 3206 cities, Port Chester's winter puts it at rank 981 for severity, while its size puts it at rank 1316 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Every constant behind this page — the 3.06 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Port Chester's 15.1°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
