Minneapolis, MN Climate Specs + Top-Rated Window Installers
Minneapolis sits in IECC climate zone 6A, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Minneapolis on this site, so Google Maps supplies the 10 ranked names you see below. Checked October 2026.

6AIECC climate zone · ENERGY STAR Northern zone
Minneapolis's climate zone, in plain terms
Minneapolis falls in IECC climate zone 6A, and ENERGY STAR separately groups Hennepin County into its Northern zone for window certification.
Those two numbers, not the brand on the box, set the U-factor and SHGC worth checking on any quote you get in Minneapolis.
A Minneapolis-St. Paul-Bloomington, MN-WI contractor who can't name either one on request is worth a second question before you sign.
Data: U.S. EPA / DOE, ENERGY STAR, ENERGY STAR Version 7.0 Climate Zones by County/ZIP (Windows, Doors, and Skylights) (V7.0); Pacific Northwest National Laboratory (DOE Building America), Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270) (2021 IECC), from the nearest NOAA station 1.5 mi away.
What FEMA's risk data says about Minneapolis
FEMA scores Hennepin County's winter-weather risk as Very High and its flood risk as Relatively High.
Winter risk in Minneapolis weighs on U-factor and condensation resistance; flood risk weighs more on sill height and drainage detailing than on the glass package.
Treat these as two separate conversations with a Minneapolis contractor, not one.

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.
