Heat pump vs. gas furnace in Scarsdale, NY
In Scarsdale, a heat pump would cost more to run each year than what you have now. $3,500 is what Scarsdale would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. 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: Scarsdale's numbers say wait.
Why Scarsdale's climate drives this number
4760 heating degree days pile up here every year, so Scarsdale has a real but manageable winter; the cooling side runs to 888 cooling degree days, where summers add a moderate cooling load. 15.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 6.1°F on file. Worked through the model, that's a seasonal COP of 3.06 on the cold-climate unit fit for this climate. A cold-climate unit is the right call in Scarsdale — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from WESTCHESTER COUNTY AIRPORT, the closest NOAA station, 6 miles out.
The month-to-month numbers for Scarsdale
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. The gas furnace it replaces burns roughly 50 Mcf a year at 17.58 per Mcf here, for a running cost near $1,208 a year (electricity here runs 29.22¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $5,966 behind.
The other scenario: no gas furnace to begin with
Not every home in Scarsdale has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $2,486 a year comes back this way, enough that the 3.2-year payback clears the $8,000 premium comfortably within the equipment's life.
How Scarsdale compares nationally
Among 3206 cities, Scarsdale's winter puts it at rank 984 for severity, while its size puts it at rank 2093 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.

More on how this number was built
Every constant behind this page — the 3.06 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. At a 15.1°F design temperature, Scarsdale sits in cold-climate territory; the guide to that class of unit explains why.
