Air Conditioning in California: what's different
Air Conditioning across California depends on the climate (IECC climate zones 2–6). Mixed climates get real summers and real winters, so the AC has a full season of work and then sits idle. Spring start-up problems such as weak capacitors, low charge and clogged drains are common.
In California specifically: inland heat. Central Valley and Inland Empire homes need strong cooling in long, hot summers.
California licenses HVAC contractors through the Contractors State License Board (CSLB), usually under the C-20 Warm-Air Heating, Ventilating and Air-Conditioning classification. Common systems in California: Gas furnace + central AC, Heat pumps, Ductless mini-splits, High-MERV filtration.
PG&E, Southern California Edison, SDG&E and municipal utilities such as LADWP and SMUD supply electricity. SoCalGas, PG&E and SDG&E supply natural gas.

FAQ
Air Conditioning questions in California
Can I get air conditioning service anywhere in California?+
Our contractor network covers many California ZIP codes. Call with your ZIP code and we will tell you whether a licensed contractor serves your address.
Does replacing my AC in California require a duct test?+
Often yes. Title 24 rules generally require duct leakage testing when HVAC equipment is replaced, with a HERS rater verifying the results.
How do I know if my AC needs repair or replacement?+
Age, refrigerant type and the failed part decide it. A newer system with a bad capacitor or fan motor is a repair. An older R-22 system with a failed compressor or leaking coil is usually a replacement.
Why is my AC running but not cooling?+
Common causes are a dirty filter or coil, low refrigerant from a leak, a failed outdoor fan or capacitor, or a frozen indoor coil. Turn the system off if you see ice and call for a diagnosis.
