Will a heat pump pay off in Babylon, NY?

Here in Babylon, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Babylon 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. The heat pump would cost about $103 more a year to run than the furnace it replaces — a premium with no payback. That's Babylon's own climate and rates talking, not a hedge or a caveat.

How cold Babylon actually gets

Degree days tell the story here: Babylon racks up 4308 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1024 cooling degree days on the cooling side. 17.1°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 10.9°F on file. Worked through the model, that's a seasonal COP of 3.11 on the cold-climate unit fit for this climate. Babylon needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. Climate figures trace to the nearest NOAA station, REPUBLIC AIRPORT, 5.5 miles from Babylon.

Babylon's running-cost comparison, in dollars

Modelled on a typical 2000-square-foot house, the heat pump draws about 3,508 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,280 a year. The gas furnace it replaces burns roughly 45 Mcf a year at 17.58 per Mcf here, for a running cost near $1,177 a year (electricity here runs 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 $5,052 behind.

The other scenario: no gas furnace to begin with

Not every home in Babylon has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $2,295 a year comes back this way, enough that the 3.5-year payback clears the $8,000 premium comfortably within the equipment's life.

How Babylon compares nationally

Ranked against the other 3206 cities covered, Babylon comes in at 1323 for heating severity — 1 would be the coldest place in the dataset — and 2784 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

What to do with this number in Babylon

Babylon, New York is home to about 12,193 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Babylon, nothing is lost by holding off until the current equipment genuinely fails.

Where Babylon's figure comes from

Every constant behind this page — the 3.11 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Babylon's 17.1°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.
