Below that spec discussion sit 10 installers, their order set by Google rating, since Huntsville is outside this site's window license file. A high rating is worth a look, not a finished decision.

What zone 3A means for a Huntsville window
Madison County's normal precipitation runs about 54.3 inches a year, with 2.4 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Huntsville.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Huntsville 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 7 mi away.
Storm and weather risk around Huntsville
FEMA rates Madison County's hurricane risk as Relatively Low and its wind risk as Relatively High.
Neither rating changes a window's energy label, but both are exactly what impact-resistance and design-pressure ratings are built to answer for a Huntsville home.
Ask specifically about design pressure and impact rating for Huntsville, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Relatively Low
- Strong wind
- Relatively High
- Winter weather
- Relatively High
