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 $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 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 record low of 10.9°F on file. 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 its running cost near $1,041 a year, against 23.28¢ per kWh for electricity. 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.
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 $8,000 spent up front comes back in about 4.7 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.
Deciding what's next in Newark, NJ
Newark, New Jersey is home to about 317,303 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 Newark, nothing is lost by holding off until the current equipment genuinely fails.

Every constant behind this page — the 3.11 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. 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.
