Will a heat pump pay off in Woodbury, NJ?
In Woodbury, a heat pump would cost more to run each year than what you have now. 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). The heat pump would cost about $16 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Woodbury's numbers say wait.
The climate behind Woodbury's payback figure
3829 heating degree days pile up here every year, so Woodbury has a real but manageable winter; the cooling side runs to 1547 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 14°F, against a record low of 10.9°F. That puts the seasonal coefficient of performance at 3.04 for the recommended cold-climate unit. A cold-climate unit is the right call in Woodbury — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, PHILADELPHIA INTERNATIONAL AI, 4.7 miles from Woodbury.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,189 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,050 a year. The gas furnace it replaces burns roughly 40 Mcf a year at 14.21 per Mcf here, for a running cost near $1,033 a year (electricity here runs 23.28¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $3,742 behind.
The other scenario: no gas furnace to begin with
Not every home in Woodbury has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,674 a year, which recovers the extra $8,000 spent going electric in roughly 4.8 years.
How Woodbury compares nationally
Woodbury lands at position 1627 out of 3206 cities on heating severity (coldest is 1), and 3171 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Woodbury's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Woodbury's 3.04 seasonal COP and payback figure. At a 14°F design temperature, Woodbury sits in cold-climate territory; the guide to that class of unit explains why.
