Heat Pump Payback in Newark, NJ
Newark, NJ: the heat pump payback math
In Newark, a heat pump would cost more to run each year than what you have now. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Unfortunately the electric bill outweighs the gas bill it replaces by about $1 a year here, so the extra spend stays unrecovered. That's Newark's own climate and rates talking, not a hedge or a caveat.

Newark's weather, in the numbers that matter
Newark 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. 17.1°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 10.9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.11 on the cold-climate unit fit for this climate. Newark 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. These numbers come from Newark Liberty International, the closest NOAA station, 2.9 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,160 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,043 a year. Newark's gas rate of $14.21 per Mcf, applied to the 40 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,041 a year, against 23.28¢ per kWh for electricity. 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.
How sensitive Newark's result is to prices
For the verdict in Newark 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 Newark; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Newark, many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Newark's answer improves. 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 $10,000 spent up front comes back in about 5.8 years.
How Newark compares nationally
Newark lands at position 1590 out of 3206 cities on heating severity (coldest is 1), and 64 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Newark'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.
