AC Replacement & Installation in California: what's different
AC Replacement & Installation 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. Title 24 duct requirements: Equipment replacement often triggers duct leakage testing and sealing under state energy rules.
California licenses HVAC contractors through the Contractors State License Board (CSLB), usually under the C-20 Warm-Air Heating, Ventilating and Air-Conditioning classification. Ask any contractor for their license number before work starts, and expect a written price for AC Replacement & Installation.
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.
