Massapequa's climate zone, in plain terms
New York-Newark-Jersey City, NY-NJ runs a January average near 35°F and climbs to about 77°F by July, a swing that adds up to roughly 4,591 heating degree days most winters, with 1,115 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Massapequa, separate from anything a brochure claims.
Zone 4A's requirement is the floor; Massapequa's specific load is what tells you whether beating that floor is worth the extra cost.
