Is a heat pump worth it in Port Washington?
Port Washington 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 $3,500 after a $2,000 federal tax credit. The heat pump would cost about $307 more a year to run than the furnace it replaces — a premium with no payback. That's Port Washington's own climate and rates talking, not a hedge or a caveat.
Port Washington's weather, in the numbers that matter
Port Washington has a cold winter that leans hard on heating equipment — 5404 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 573 cooling degree days. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is -0.4°F, against a record low of -7.1°F. That puts the seasonal coefficient of performance at 2.69 for the recommended cold-climate unit. A cold-climate unit is the right call in Port Washington — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Port Washington's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 5,087 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,052 a year. The gas furnace it replaces burns roughly 56 Mcf a year at 10.74 per Mcf here, for a running cost near $745 a year (electricity here runs 18.87¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $8,112 behind.
Electric resistance heat in Port Washington, compared
Not every home in Port Washington has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,670 a year comes back this way, enough that the 4.8-year payback clears the $8,000 premium comfortably within the equipment's life.
How Port Washington compares nationally
Port Washington lands at position 427 out of 3206 cities on heating severity (coldest is 1), and 2684 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
