Heat Pump Payback in Elizabeth, NJ
Heat pump vs. gas furnace in Elizabeth, NJ
Here in Elizabeth, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Elizabeth 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 $1 a year here, so the extra spend stays unrecovered. That's Elizabeth's own climate and rates talking, not a hedge or a caveat.

Elizabeth's weather, in the numbers that matter
Degree days tell the story here: Elizabeth racks up 3881 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1548 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 17.1°F here (coldest 2024 reading 10.9°F), which works out to a seasonal COP of 3.11 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, Elizabeth sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Newark Liberty International, 1.7 miles from Elizabeth.
Elizabeth's running-cost comparison, in dollars
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 including the old AC (electricity here runs 23.28¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $5,522 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Elizabeth's answer
For the verdict in Elizabeth to flip, electricity would need to drop to about 23.2¢/kWh from 23.28¢, or gas climb past $14.25 per Mcf from $14.21. 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 Elizabeth; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Plenty of homes in Elizabeth heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,712 a year, which recovers the extra $10,000 spent going electric in roughly 5.8 years.
Elizabeth against the rest of the country
Elizabeth lands at position 1591 out of 3206 cities on heating severity (coldest is 1), and 201 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Elizabeth
Elizabeth, New Jersey is home to about 140,413 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 Elizabeth, nothing is lost by holding off until the current equipment genuinely fails.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Elizabeth's 3.11 seasonal COP and payback figure. Elizabeth'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.
