Heat Pump Payback in Hammonton, NJ
Will a heat pump pay off in Hammonton, NJ?
In Hammonton, 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 $5,500 more up front here. Unfortunately the electric bill outweighs the gas bill it replaces by about $68 a year here, so the extra spend stays unrecovered. There's no spin on that: Hammonton's numbers say wait.

Why Hammonton's climate drives this number
Hammonton has a real but manageable winter, 4115 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. Sizing runs off the design temperature, not the average day: 12.9°F here (coldest 2024 reading 7°F), which works out to a seasonal COP of 3.01 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in Hammonton, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

The yearly running costs in Hammonton
A 2000-square-foot house here would pull roughly 3,462 heating kilowatt-hours annually on top of cooling, totalling about $1,054 a year on electricity. That compares with roughly 43 Mcf a year of gas at Hammonton's $14.21 per-Mcf rate, about $986 a year with the old AC included, against a local electricity rate of 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 $6,521 behind.
How sensitive Hammonton's result is to prices
The heat pump would become the cheaper option in Hammonton if electricity fell to 20.9¢/kWh (from 23.28¢) or gas rose above $15.80 per Mcf (from $14.21). At today's prices a cheaper quote cannot rescue the gas comparison in Hammonton, since there is no yearly saving to recover it from.
Electric resistance heat in Hammonton, compared
Not every home in Hammonton has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. The saving here runs about $1,749 a year, which recovers the extra $10,000 spent going electric in roughly 5.7 years.
Where Hammonton ranks in this dataset
Hammonton lands at position 1443 out of 3206 cities on heating severity (coldest is 1), and 2389 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Hammonton's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Hammonton's 3.01 seasonal COP and payback figure. Hammonton's 12.9°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.
