Heat Pump Payback in Scarsdale, NY
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. $5,500 is what Scarsdale would pay extra to go electric rather than replace the furnace and AC with the same again. 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 low of 6.1°F in the 2024 station record. 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 yearly running costs in 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 including the old AC (electricity here runs 29.22¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $7,966 behind.
How sensitive Scarsdale's result is to prices
The heat pump would become the cheaper option in Scarsdale if electricity fell to 24.6¢/kWh (from 29.22¢) or gas rose above $20.90 per Mcf (from $17.58). At today's prices a cheaper quote cannot rescue the gas comparison in Scarsdale, since there is no yearly saving to recover it from.
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 4-year payback clears the $10,000 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.
