Heat Pump Payback in Garden City, NY
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. $5,500 is what Garden City would pay extra to go electric rather than replace the furnace and AC with the same again. 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 (coldest 2024 reading 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 including the old AC (electricity here runs 29.22¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $6,926 behind after 15 years compared with replacing the furnace and AC like-for-like.
How sensitive Garden City's result is to prices
For the verdict in Garden City to flip, electricity would need to drop to about 26.0¢/kWh from 29.22¢, or gas climb past $19.77 per Mcf from $17.58. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Garden City; the case for one here rests on comfort, cooling, or replacing electric heat instead.
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 $10,000 spent going electric in roughly 4.5 years.
