Heat pump vs. gas furnace in Wallington, NJ

Here in Wallington, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Running costs here land $66 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Wallington's numbers say wait.

The climate behind Wallington's payback figure

Degree days tell the story here: Wallington racks up 4363 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1248 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 15.1°F here (record low 9°F), which works out to a seasonal COP of 3.06 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, Wallington sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from TETERBORO AIRPORT, the closest NOAA station, 2.4 miles out.

Wallington's running-cost comparison, in dollars

Modelled on a typical 2000-square-foot house, the heat pump draws about 3,610 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,088 a year. That compares with roughly 45 Mcf a year of gas at Wallington's 14.21 per-Mcf rate — about $1,022 a year — against a local electricity rate of 23.28¢/kWh. Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $4,490 behind.

The other scenario: no gas furnace to begin with

Gas isn't universal in Wallington — many houses run on electric heat already. 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 $1,860 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 4.3 years.

Wallington against the rest of the country

Ranked against the other 3206 cities covered, Wallington comes in at 1266 for heating severity — 1 would be the coldest place in the dataset — and 2803 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

Deciding what's next in Wallington, NJ

About 12,060 people live in Wallington, New Jersey, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.

Ask a local HVAC contractor for a quote before committing either way.

More on how this number was built

Every constant behind this page — the 3.06 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Wallington's 15.1°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.
