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 2–20 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.

FAQ

Common questions about commercial ac repair in Los Angeles

How fast can you respond to a commercial AC emergency in Los Angeles?
Our target response for commercial AC emergencies is 2–4 hours during business hours. For after-hours commercial emergencies, we aim for 2-hour response. We're available 24/7 at (323) 970-3113 for commercial emergency calls.
Do you service rooftop units (RTUs)?
Yes. We service packaged rooftop units in the 2–20 ton range from all major brands including Carrier, Lennox, Trane, Daikin, York, and Rheem. RTU service includes rooftop access, proper safety procedures, and familiarity with the specific service requirements of packaged units.
What is the most common reason a commercial RTU fails?
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 coil cleaning usually restores operation.
How much does commercial AC repair cost in Los Angeles?
Commercial AC repair pricing varies significantly by equipment type, failure mode, and parts required. Service call/diagnostic fee: $150–$250. Common repairs: commercial capacitor $200–$400, commercial contactor $200–$400, refrigerant repair and recharge $400–$1,000+, control board $500–$1,200. We provide a written estimate before any repair work begins.
Can you service commercial mini split systems?
Yes. We service commercial mini split multi-zone systems from Mitsubishi Electric, Daikin, Fujitsu, LG, and other commercial mini split manufacturers. Commercial mini split service includes system diagnostic via service ports, refrigerant system service, and controller/BMS integration issues.
Do you service commercial HVAC under a service contract?
Yes. We offer commercial maintenance contracts that include scheduled preventive maintenance visits, priority emergency response, and documented service records. Commercial maintenance significantly reduces emergency repair frequency and extends equipment life. Call (323) 970-3113 to discuss contract options for your property.
What commercial AC brands do you service?
We service Carrier, Lennox, Trane, York, Daikin, Mitsubishi Electric Commercial, Fujitsu Commercial, Rheem, Goodman, American Standard, and all other commercial HVAC brands. We carry service manuals and access manufacturer technical support for all major brands.
Is there an after-hours service fee for commercial emergency calls?
Yes. After-hours commercial emergency service carries a premium service fee. We're transparent about pricing before dispatch β€” call (323) 970-3113 and we'll confirm the after-hours rate for commercial service at the time of your call.
