Chino Hills's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups San Bernardino County into its South-Central zone, the U-factor and SHGC target worth checking against any quote you get in Chino Hills. Below that spec discussion sit 9 installers, their order set by Google rating, since Chino Hills is outside this site's window license file. A high rating is worth a look, not a finished decision.

Chino Hills's climate zone, in plain terms
Riverside-San Bernardino-Ontario, CA runs a January average near 56°F and climbs to about 78°F by July, a swing that adds up to roughly 1,387 heating degree days most winters, with 1,817 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Chino Hills, separate from anything a brochure claims.
Zone 3B's requirement is the floor; Chino Hills's specific load is what tells you whether beating that floor is worth the extra cost.

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.
