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

FAQ
AC Replacement & Installation questions
Does replacing my AC in Los Angeles require a duct test?+
Usually yes. Title 24 typically requires duct leakage testing when HVAC equipment is replaced, verified by a HERS rater.
What size AC do I need?+
It depends on the house, not just square footage. A Manual J calculation accounts for windows, insulation, shading, orientation and your local climate. Oversized systems short-cycle and leave the house clammy.
Do I need a permit to replace my AC?+
In most places, yes. Equipment replacement usually requires a mechanical permit from your city or county, and the contractor normally pulls it.
