What zone 5A means for a Cleveland window
Cleveland, OH runs a January average near 29°F and climbs to about 74°F by July, a swing that adds up to roughly 5,513 heating degree days most winters, with 925 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Cleveland, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Cleveland's specific load is what tells you whether beating that floor is worth the extra cost.
