Heat Pump Payback in Dunkirk, NY
Dunkirk, NY: the heat pump payback math
Dunkirk is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Unfortunately the electric bill outweighs the gas bill it replaces by about $188 a year here, so the extra spend stays unrecovered. There's no spin on that: Dunkirk's numbers say wait.

The climate behind Dunkirk's payback figure
Dunkirk has a real but manageable winter, 4723 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 986 cooling degree days. 10.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 1°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.96 on the cold-climate unit fit for this climate. Dunkirk 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 Chautauqua Co/Dunkirk Airport, the closest NOAA station, 3.2 miles out.
Dunkirk's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 4,040 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,426 a year. The gas furnace it replaces burns roughly 49 Mcf a year at $17.58 per Mcf here, for a running cost near $1,238 a year including the old AC (electricity here runs 29.22¢/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 $8,322 behind.
What would change Dunkirk's answer
The heat pump would become the cheaper option in Dunkirk if electricity fell to 24.0¢/kWh (from 29.22¢) or gas rose above $21.40 per Mcf (from $17.58). At today's prices a cheaper quote cannot rescue the gas comparison in Dunkirk, since there is no yearly saving to recover it from.
If your home heats with electric baseboard instead of gas
Plenty of homes in Dunkirk heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Dunkirk's answer improves. The saving here runs about $2,442 a year, which recovers the extra $10,000 spent going electric in roughly 4.1 years.
Where Dunkirk ranks in this dataset
Ranked against the other 3206 cities covered, Dunkirk comes in at 1004 for heating severity, 1 would be the coldest place in the dataset, and 2750 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
