Is a heat pump worth it in Westfield?
Westfield is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Westfield would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Running costs here land $1 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Westfield's numbers say wait.
Why Westfield's climate drives this number
3881 heating degree days pile up here every year, so Westfield has a real but manageable winter; the cooling side runs to 1548 cooling degree days, where summers are hot enough that cooling matters as much as heating. 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. Below the 25°F line where a standard machine starts leaning on resistance backup, Westfield sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from NEWARK LIBERTY INTERNATIONAL, the closest NOAA station, 9.4 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. 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). 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 $3,522 behind.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Westfield — many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. 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.
Where Westfield ranks in this dataset
Westfield lands at position 1596 out of 3206 cities on heating severity (coldest is 1), and 1275 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 Westfield
About 32,050 people live in Westfield, 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.

More on how this number was built
Every constant behind this page — the 3.11 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Westfield'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.
