What zone 3B means for a Seal Beach window
Los Angeles-Long Beach-Anaheim, CA runs a January average near 57°F and climbs to about 73°F by July, a swing that adds up to roughly 1,173 heating degree days most winters, with 1,166 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Seal Beach, separate from anything a brochure claims.
Zone 3B's requirement is the floor; Seal Beach's specific load is what tells you whether beating that floor is worth the extra cost.
