Great Neck's climate zone, in plain terms
New York-Newark-Jersey City, NY-NJ runs a January average near 34°F and climbs to about 78°F by July, a swing that adds up to roughly 4,583 heating degree days most winters, with 1,278 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Great Neck, separate from anything a brochure claims.
Zone 4A's requirement is the floor; Great Neck's specific load is what tells you whether beating that floor is worth the extra cost.
