What to expect from LC Heating & Air
### Commercial AC Repair Throughout Los Angeles County A failed air conditioner in a commercial space is a business problem, not just a comfort problem. Customer-facing businesses β retail, restaurants, medical offices β cannot operate without functional cooling during a Los Angeles summer. LC Heating & Air prioritizes commercial AC repair calls and targets rapid response throughout LA County to minimize the time your business operates without cooling.
Overview
### What We Service for Commercial AC We diagnose and repair commercial split systems, packaged rooftop units (RTUs) in the 2β20 ton range, commercial mini split multi-zone systems, and commercial heat pump systems. Our technicians carry common commercial AC repair parts for all major brands β commercial capacitors, contactors, control boards, refrigerant, and common RTU components β allowing us to complete most commercial repairs in a single visit.
### Commercial AC Failure Modes Commercial AC failures share many characteristics with residential failures but at higher capacity levels. Common commercial calls: RTU compressor lockout due to high discharge pressure (usually dirty condenser coil on a rooftop unit exposed to LA's dusty conditions), failed commercial contactor, low refrigerant from connection leaks on commercial line sets, economizer damper failures causing outside air to overload the cooling system, and commercial control board failures. We diagnose accurately before recommending repairs.
### After-Hours and Weekend Commercial Service We understand that commercial HVAC emergencies don't wait for business hours. LC Heating & Air provides after-hours and weekend commercial AC service throughout Los Angeles County. Call (323) 970-3113 at any time for commercial emergency response.

What customers say about commercial ac repair
Verified reviews from Los Angeles homeowners who used our commercial ac repair service.
βLC handles all three of our restaurant locations in Koreatown. Rooftop unit on one site went down on a Friday night β they had it running by Saturday afternoon. No service contract drama, just got the job done.β
βLC has maintained the HVAC systems at our Glendale office building for 3 years. Reliable, responsive, and they keep great records of every system so there are no surprises. Highly recommend for commercial properties.β
βOur AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.β
