Livonia, MI Climate Specs + Top-Rated Window Installers
Livonia 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 Livonia on this site, so Google Maps supplies the 10 ranked names you see below. Checked September 2026.

Livonia's climate zone, in plain terms
Detroit-Warren-Dearborn, MI runs a January average near 23°F and climbs to about 71°F by July, a swing that adds up to roughly 6,867 heating degree days most winters, with 573 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Livonia, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Livonia's specific load is what tells you whether beating that floor is worth the extra cost.

The order below weighs a Google rating against its review count, the same way this site weighs a U-factor against a brochure claim: on the number, not the name. Treat it as a rating, never as proof of a license, bond or HVHZ approval.
