AC Replacement & Installation in Los Angeles: what's different
AC installation in Los Angeles depends on where you live. Coastal neighborhoods may only need cooling during heat waves, while the San Fernando Valley regularly passes 100°F and needs a system sized for long, hot afternoons.
California's Title 24 rules usually require duct leakage testing and verification when equipment is replaced, so quotes should include HERS testing. Many LA homeowners now choose a heat pump instead of a straight AC, replacing an old gas wall or floor furnace at the same time.
Ask whether the quote includes the HERS duct test, the permit, and any electrical panel work. Older LA homes sometimes need a panel or circuit upgrade for a new system.
Los Angeles climate
Dry, mild winters; warm to very hot summers inland; and Santa Ana wind events that bring heat, dry air and wildfire smoke.
