Heat Pump Payback in Collingswood, NJ
Collingswood, NJ: the heat pump payback math
In Collingswood, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. That premium is recovered through $37 of lower running costs every year, landing the payback clock at roughly 146.9 years. That's a technicality, not a recommendation, for anyone actually living in Collingswood.

Collingswood's weather, in the numbers that matter
3607 heating degree days pile up here every year, so Collingswood has a real but manageable winter; the cooling side runs to 1669 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 19.8°F, and the coldest daily reading in the 2024 station record was 13.8°F. That puts the seasonal coefficient of performance at 3.18 for the recommended cold-climate unit. Collingswood needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from Philadelphia, the closest NOAA station, 4.3 miles out.
Collingswood's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 2,872 heating kilowatt-hours annually on top of cooling, totalling about $1,000 a year on electricity. The gas furnace it replaces burns roughly 38 Mcf a year at $14.21 per Mcf here, for a running cost near $1,037 a year including the old AC (electricity here runs 23.28¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $4,938 behind.
How sensitive Collingswood's result is to prices
Gas would only overtake the heat pump in Collingswood if electricity rose past 25.0¢/kWh from 23.28¢, or gas fell under $13.21 per Mcf from $14.21. A useful quote test for Collingswood: the heat pump is worth it within a decade if it costs less than $370 more than replacing the furnace and AC, and within 7 years if the gap is under $259.
The other scenario: no gas furnace to begin with
Plenty of homes in Collingswood heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Collingswood's answer improves. Switching saves about $1,630 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 6.1 years.
How Collingswood compares nationally
Collingswood lands at position 1737 out of 3206 cities on heating severity (coldest is 1), and 2469 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
