What zone 3B means for a Valencia window
Los Angeles-Long Beach-Anaheim, CA runs a January average near 55°F and climbs to about 79°F by July, a swing that adds up to roughly 1,677 heating degree days most winters, with 1,902 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Valencia, separate from anything a brochure claims.
Zone 3B's requirement is the floor; Valencia's specific load is what tells you whether beating that floor is worth the extra cost.
