Avon Lake sits in IECC climate zone 5A, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Avon Lake on this site, so Google Maps supplies the 8 ranked names you see below. Checked September 2026.

What zone 5A means for a Avon Lake window
Cleveland, OH runs a January average near 29°F and climbs to about 75°F by July, a swing that adds up to roughly 5,436 heating degree days most winters, with 963 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Avon Lake, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Avon Lake's specific load is what tells you whether beating that floor is worth the extra cost.
