Johnson Controls Commercial Rooftop & Applied Hvac Service in Orange County
Johnson Controls is the parent of York, Coleman and Luxaire, and it also sells commercial equipment under its own name - the rooftop units, applied chillers and building controls on Orange County office parks, retail centers, medical buildings and warehouses. Commercial HVAC is a different discipline than residential: the units are three-phase, the controls are networked, and a failure shuts down a business rather than making a family uncomfortable. We service both sides.

Common Johnson Controls Problems We Fix
What actually goes wrong with Johnson Controls equipment in Orange County, and what the repair really involves.
Belt, bearing and sheave wear on rooftop units
The leading scheduled-maintenance item on commercial RTUs and the leading cause of an unplanned shutdown when it gets skipped. Cheap on a schedule, expensive on a Friday afternoon.
Economizer failure
A stuck economizer damper wastes conditioned air year-round and almost never triggers an alarm. It shows up on the utility bill months before anyone notices.
Three-phase power and contactor faults
Commercial units fail differently than residential. Single-phasing quietly destroys compressors, and diagnosing it takes an electrician as much as an HVAC tech - we hold both licenses, CSLB #1108650.
Compressor and refrigerant circuit failures
On multi-circuit rooftop units, one dead circuit halves capacity without stopping the unit. Tenants complain long before the equipment reports a fault.
Controls and BAS integration
Networked controls mean a working unit can still fail to condition the space. We diagnose the control layer, not just the machinery.
