Enterprise, NV Climate Specs + Top-Rated Window Installers
Enterprise sits in IECC climate zone 3B, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Enterprise on this site, so Google Maps supplies the 10 ranked names you see below. Checked October 2026.

What zone 3B means for a Enterprise window
Las Vegas-Henderson-North Las Vegas, NV runs a January average near 48°F and climbs to about 93°F by July, a swing that adds up to roughly 2,017 heating degree days most winters, with 3,563 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Enterprise, separate from anything a brochure claims.
Zone 3B's requirement is the floor; Enterprise's specific load is what tells you whether beating that floor is worth the extra cost.
