Should Bergenfield switch to a heat pump?
In Bergenfield, 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. The heat pump would cost about $66 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Bergenfield's numbers say wait.
The climate behind Bergenfield's payback figure
Bergenfield has a real but manageable winter — 4363 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1248 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 15.1°F, against a record low of 9°F. That puts the seasonal coefficient of performance at 3.06 for the recommended cold-climate unit. A cold-climate unit is the right call in Bergenfield — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from TETERBORO AIRPORT, the closest NOAA station, 6 miles out.
The month-to-month numbers for Bergenfield
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. The gas furnace it replaces burns roughly 45 Mcf a year at 14.21 per Mcf here, for a running cost near $1,022 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 $4,490 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in Bergenfield heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Bergenfield's answer improves. The saving here runs about $1,860 a year, which recovers the extra $8,000 spent going electric in roughly 4.3 years.
Where Bergenfield ranks in this dataset
Bergenfield lands at position 1245 out of 3206 cities on heating severity (coldest is 1), and 1387 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 Bergenfield
About 28,921 people live in Bergenfield, 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
Nothing above is a black box: the methodology guide shows the full arithmetic behind Bergenfield's 3.06 seasonal COP and payback figure. At a 15.1°F design temperature, Bergenfield sits in cold-climate territory; the guide to that class of unit explains why.
