What Homeowners Need to Know About California's SEER2 Regulations
As of January 2023, the Department of Energy implemented new testing and efficiency metrics called SEER2. In Southern California, the minimum rating for new split-system AC installations rose to 14.3 SEER2. While this makes newer units slightly more expensive upfront, it ensures that every installation in Southern California provides significant electric bill relief. If you are replacing an older 10 SEER system, upgrading to a 14.3 SEER2 or higher can reduce cooling bills by up to 30%.
