Haverstraw's climate zone, in plain terms
New York-Newark-Jersey City, NY-NJ runs a January average near 26°F and climbs to about 72°F by July, a swing that adds up to roughly 6,234 heating degree days most winters, with 590 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Haverstraw, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Haverstraw's specific load is what tells you whether beating that floor is worth the extra cost.
