What to expect from LC Heating & Air
### Rooftop Unit (RTU) Service in Los Angeles Packaged rooftop units are the most common commercial HVAC configuration in Los Angeles — they combine the compressor, condenser, evaporator, and furnace sections in a single weatherproof cabinet mounted on the roof. The self-contained design simplifies installation, but rooftop service requires working in exposed conditions on building rooftops — LC Heating & Air is equipped and experienced for this work throughout LA County.
Overview
### RTU Service Challenges in Los Angeles LA's climate creates specific RTU maintenance challenges. The dry, dusty conditions — especially during Santa Ana winds — load condenser coils with debris that causes high-pressure lockouts if coils aren't cleaned regularly. Sun exposure accelerates refrigerant hose and seal degradation. Nesting birds and rodents frequently enter RTU cabinets through service access panels, damaging wiring and blocking drain pans. We address all of these LA-specific conditions in our RTU service visits.
### RTU Replacement Considerations Rooftop unit replacement in commercial applications involves roof deck structural assessment (RTUs are heavy), curb compatibility (the raised mounting frame that the RTU sits on), electrical service capacity, and gas connection requirements. Some RTU replacements can use the existing curb; others require curb modification or replacement. We assess all of these factors before proposing replacement equipment.
### All Major Commercial RTU Brands We service and replace Carrier, Lennox, Trane, York, Daikin, Rheem, Goodman, and all other major commercial RTU brands in the 2–20 ton range. We maintain relationships with commercial equipment distributors that allow us to source replacement units quickly for commercial emergency replacement situations.

What customers say about rooftop unit service
Verified reviews from Los Angeles homeowners who used our rooftop unit service service.
“LC handles all three of our restaurant locations in Koreatown. Rooftop unit on one site went down on a Friday night — they had it running by Saturday afternoon. No service contract drama, just got the job done.”
“LC 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.”
“Our 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.”
