Heat Pump Payback in Bergenfield, NJ
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 $5,500. 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, and the coldest daily reading in the 2024 station record was 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 yearly running costs in 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 including the old AC (electricity here runs 23.28¢/kWh). With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $6,490 behind.
What would change Bergenfield's answer
The heat pump would become the cheaper option in Bergenfield if electricity fell to 21.1¢/kWh (from 23.28¢) or gas rose above $15.66 per Mcf (from $14.21). At today's prices a cheaper quote cannot rescue the gas comparison in Bergenfield, since there is no yearly saving to recover it from.
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 $10,000 spent going electric in roughly 5.4 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.
