Will a heat pump pay off in Carteret, NJ?
Carteret is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Unfortunately the electric bill outweighs the gas bill it replaces by about $1 a year here, so the extra spend stays unrecovered. That's Carteret's own climate and rates talking, not a hedge or a caveat.
How cold Carteret actually gets
Carteret has a real but manageable winter — 3881 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1548 cooling degree days. Sizing runs off the design temperature, not the average day: 17.1°F here (record low 10.9°F), which works out to a seasonal COP of 3.11 for the cold-climate class of unit this climate calls for. Carteret 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, NEWARK LIBERTY INTERNATIONAL, 7.5 miles from Carteret.
The month-to-month numbers for Carteret
A 2000-square-foot house here would pull roughly 3,160 heating kilowatt-hours annually on top of cooling, totalling about $1,043 a year on electricity. The gas furnace it replaces burns roughly 40 Mcf a year at 14.21 per Mcf here, for a running cost near $1,041 a year (electricity here runs 23.28¢/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 $3,522 behind.
If your home heats with electric baseboard instead of gas
Plenty of homes in Carteret heat with electricity alone, no gas line involved. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $1,712 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 4.7 years.
Carteret against the rest of the country
Ranked against the other 3206 cities covered, Carteret comes in at 1598 for heating severity — 1 would be the coldest place in the dataset — and 1541 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Carteret, New Jersey is home to about 26,003 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 Carteret, nothing is lost by holding off until the current equipment genuinely fails.
