Andover's Climate Data and Its Top-Rated Window Pros

Andover's climate zone, in plain terms
Anoka County's normal precipitation runs about 28.8 inches a year, with 44.1 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Andover.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Andover buyer benefits from checking both instead of assuming one implies the other.
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 2.2 mi away.

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.
