Commercial rooftop and packaged unit repair

Describe the affected space and mechanical symptoms

Tell us whether one tenant suite, dining room, warehouse zone or the entire site is affected. Include when the cooling or heating concern started, any visible thermostat or building automation messages, and whether multiple packaged units appear to be involved.

Our technicians service all major commercial RTU manufacturers including Carrier, Trane, Lennox Commercial, York, Daikin, and Rheem.

Prepare roof access and safety protocols before dispatch

Have your building contact confirm how the service team can reach the equipment safely. Share any roof hatch keys, exterior cage ladder combinations, security check-in rules, and property management restrictions. Staff should not climb onto the roof to collect unit model numbers before the visit.

Systematic diagnostics and crane replacement coordination

A warm space symptom requires methodical electrical and refrigerant testing. We isolate blown fuses, failed contactors, faulty economizer actuators, cracked heat exchangers, and compressor ground faults before recommending repairs. For units requiring full replacement, we coordinate curb adapters, crane permits, and expedited equipment delivery.

Regional commercial coverage

We provide rapid service across the Inland Empire, San Bernardino County, Riverside County, and Los Angeles County border cities. For multi-site property managers, provide your site list and prioritize urgent tenant disruptions.
