Should Valley Stream switch to a heat pump?
In Valley Stream, 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 $3,500 more up front here (already netting out a $2,000 tax credit). Running costs here land $72 a year HIGHER than the furnace it replaces, so that premium is never recovered. There's no spin on that: Valley Stream's numbers say wait.
Why Valley Stream's climate drives this number
Degree days tell the story here: Valley Stream racks up 4105 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1134 cooling degree days on the cooling side. 18°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 12°F on file. Worked through the model, that's a seasonal COP of 3.13 on the cold-climate unit fit for this climate. Valley Stream 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 JOHN F KENNEDY INTERNATIONAL, the closest NOAA station, 3.6 miles out.
Valley Stream's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 3,321 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,253 a year. Valley Stream's gas rate of 17.58 per Mcf, applied to the 43 Mcf a year the furnace burns, puts its running cost near $1,181 a year, against 29.22¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $4,578 behind.
Electric resistance heat in Valley Stream, compared
Gas isn't universal in Valley Stream — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Valley Stream's answer improves. About $2,214 a year comes back this way, enough that the 3.6-year payback clears the $8,000 premium comfortably within the equipment's life.
How Valley Stream compares nationally
Ranked against the other 3206 cities covered, Valley Stream comes in at 1453 for heating severity — 1 would be the coldest place in the dataset — and 1025 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.

About 40,232 people live in Valley Stream, New York, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
Where Valley Stream's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Valley Stream's 3.13 seasonal COP and payback figure. Valley Stream's 18°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
