What zone 4A means for a North Middleton window
Harrisburg-Carlisle, PA runs a January average near 29°F and climbs to about 74°F by July, a swing that adds up to roughly 5,559 heating degree days most winters, with 826 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in North Middleton, separate from anything a brochure claims.
Zone 4A's requirement is the floor; North Middleton's specific load is what tells you whether beating that floor is worth the extra cost.
