A failed air conditioner in a commercial space is a business problem, not just a comfort problem. Customer-facing businesses—retail, restaurants, medical offices—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.
When your commercial AC goes down, you need a technician who understands that downtime costs money. At LC Heating & Air, we treat commercial cooling failures as high-priority events. Whether you are running a retail space, a restaurant, or an office, our goal is to get your system back online as quickly as possible with a permanent, professional fix.
I am Leo, and I run LC Heating & Air. We don't believe in quick-fix band-aids that fail a week later. We diagnose the root cause of the failure—whether it's a control board issue, a refrigerant leak, or a locked-out rooftop unit—and provide a written estimate before we start any work. You will know exactly what is wrong and what it will cost to fix it.

Common Commercial AC Failure Modes
In Los Angeles, the most common commercial RTU failure we see is high-pressure lockout due to dirty condenser coils. RTU condenser coils on LA rooftops are exposed to dust, smog particulates, and bird activity. When the coil becomes coated with debris, head pressure rises, the high-pressure safety trips, and the compressor locks out. A professional coil cleaning usually restores operation.
We also frequently see failed commercial contactors, low refrigerant levels from connection leaks on commercial line sets, economizer damper failures that cause outside air to overload the cooling system, and commercial control board failures. We diagnose these accurately before recommending repairs, ensuring we don't waste your time or budget on parts that aren't the problem.
Repair vs. Replace: Making the Right Call
If the system is worth repairing, we will tell you. If the pattern points to replacement, we will explain why. We look at the age of the equipment, the cost of the repair, and the overall reliability of the unit. If a repair is a temporary fix for a dying compressor or a failing heat exchanger, we will be honest about it.
Our goal is to provide a solution that makes sense for your business. We don't push for replacement unless it is the most practical long-term decision for your property. We provide a written estimate so you can make an informed decision before anyone touches the equipment.

What Beverly Hills customers say about commercial ac repair
Verified reviews from homeowners in Beverly Hills and nearby neighborhoods who used our commercial ac repair service.
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Pilot light kept going out on our older furnace. LC came out, replaced the thermocouple, cleaned the burner assembly, and did a full safety check. Fast, affordable, and they showed me how to relight it safely in the future.”
