Heat pump vs. gas furnace in Garden City, NY

Here in Garden City, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Garden City 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. Unfortunately the electric bill outweighs the gas bill it replaces by about $95 a year here, so the extra spend stays unrecovered. That's Garden City's own climate and rates talking, not a hedge or a caveat.

Garden City's weather, in the numbers that matter

Degree days tell the story here: Garden City racks up 4161 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 906 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 19.2°F here (record low 13.8°F), which works out to a seasonal COP of 3.16 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Garden City sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from KINGS POINT, the closest NOAA station, 8.3 miles out.

Garden City's running-cost comparison, in dollars

A 2000-square-foot house here would pull roughly 3,334 heating kilowatt-hours annually on top of cooling, totalling about $1,200 a year on electricity. The gas furnace it replaces burns roughly 43 Mcf a year at 17.58 per Mcf here, for a running cost near $1,105 a year (electricity here runs 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 $4,926 behind.

Electric resistance heat in Garden City, compared

Not every home in Garden City has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $2,222 a year, which recovers the extra $8,000 spent going electric in roughly 3.6 years.

How Garden City compares nationally

Ranked against the other 3206 cities covered, Garden City comes in at 1424 for heating severity — 1 would be the coldest place in the dataset — and 1718 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Every constant behind this page — the 3.16 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Garden City's 19.2°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.
