What zone 2B means for a Avondale window
Phoenix-Mesa-Chandler, AZ runs a January average near 55°F and climbs to about 94°F by July, a swing that adds up to roughly 1,103 heating degree days most winters, with 4,398 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Avondale, separate from anything a brochure claims.
Zone 2B's requirement is the floor; Avondale's specific load is what tells you whether beating that floor is worth the extra cost.
