Frequently Asked Questions

How much does AC installation cost in Los Angeles?

AC installation in Los Angeles costs $3,000-$7,000 for a central air system. A full HVAC system (AC + furnace) runs $5,000-$12,000. Mini splits cost $2,000-$5,000. Price depends on home size, SEER rating, and ductwork needs.

How long does AC installation take?

Standard replacement takes 4-8 hours (1 day). New installation with ductwork takes 2-5 days. Mini split installation takes 1-2 days.

What size AC do I need?
