Heat Pump Payback in New Rochelle, NY
New Rochelle, NY: the heat pump payback math
New Rochelle is a place where a heat pump genuinely costs more to operate than the alternative. $5,500 is what New Rochelle 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 New Rochelle's own climate and rates talking, not a hedge or a caveat.

How cold New Rochelle actually gets
4161 heating degree days pile up here every year, so New Rochelle has a real but manageable winter; the cooling side runs to 906 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 19.2°F, and the coldest daily reading in the 2024 station record was 13.8°F. That puts the seasonal coefficient of performance at 3.16 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, New Rochelle sits firmly in cold-climate territory, so that's the class of unit priced here.

New Rochelle's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 3,334 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,200 a year. 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.
The break-even point in New Rochelle
For the verdict in New Rochelle 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 New Rochelle; the case for one here rests on comfort, cooling, or replacing electric heat instead.
If your home heats with electric baseboard instead of gas
Gas isn't universal in New Rochelle, many houses run on electric heat already. 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.
