Should Freeport switch to a heat pump?
Here in Freeport, 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 $3,500 more up front here (already netting out a $2,000 tax credit). Unfortunately the electric bill outweighs the gas bill it replaces by about $72 a year here, so the extra spend stays unrecovered. That's Freeport's own climate and rates talking, not a hedge or a caveat.
Freeport's weather, in the numbers that matter
Freeport has a real but manageable winter — 4105 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 1134 cooling degree days. Sizing runs off the design temperature, not the average day: 18°F here (record low 12°F), which works out to a seasonal COP of 3.13 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Freeport sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from JOHN F KENNEDY INTERNATIONAL, the closest NOAA station, 9.4 miles out.
The month-to-month numbers for Freeport
A 2000-square-foot house here would pull roughly 3,321 heating kilowatt-hours annually on top of cooling, totalling about $1,253 a year on electricity. The gas furnace it replaces burns roughly 43 Mcf a year at 17.58 per Mcf here, for a running cost near $1,181 a year (electricity here runs 29.22¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $4,578 behind.
If your home heats with electric baseboard instead of gas
Not every home in Freeport 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 $2,214 a year, which recovers the extra $8,000 spent going electric in roughly 3.6 years.
Where Freeport ranks in this dataset
Freeport lands at position 1452 out of 3206 cities on heating severity (coldest is 1), and 937 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
What to do with this number in Freeport
Freeport, New York is home to about 44,028 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Freeport, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.
More on how this number was built
Nothing above is a black box: the methodology guide shows the full arithmetic behind Freeport's 3.13 seasonal COP and payback figure. Freeport's 18°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
