Heat Pump Payback in Garfield, NJ
Will a heat pump pay off in Garfield, NJ?
Here in Garfield, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Running costs here land $66 a year higher than the furnace it replaces, so that premium is never recovered. That's Garfield's own climate and rates talking, not a hedge or a caveat.

Garfield's weather, in the numbers that matter
Garfield 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. Garfield 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. Climate figures trace to the nearest NOAA station, Teterboro Airport, 3.2 miles from Garfield.
The yearly running costs in Garfield
Electricity use for heating alone comes out to about 3,610 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,088 a year. Garfield's gas rate of $14.21 per Mcf, applied to the 45 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,022 a year, against 23.28¢ per kWh for electricity. Because the heat pump costs more to run here, the gap only widens with time: $6,490 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Garfield
For the verdict in Garfield to flip, electricity would need to drop to about 21.1¢/kWh from 23.28¢, or gas climb past $15.66 per Mcf from $14.21. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Garfield; the case for one here rests on comfort, cooling, or replacing electric heat instead.
If your home heats with electric baseboard instead of gas
Plenty of homes in Garfield heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,860 a year comes back this way, enough that the 5.4-year payback clears the $10,000 premium comfortably within the equipment's life.
