Dependable rooftop package unit service, commercial air distribution, and preventive maintenance plans for business owners across Los Angeles.
Schedule Commercial ConsultationWhen cooling systems fail in retail stores, office buildings, server rooms, or restaurants, tenant comfort drops and business operations are disrupted. Commercial HVAC equipment demands specialized technical expertise to manage higher tonnage systems, complex economizers, and rooftop accessibility.
We partner with Los Angeles property managers and facility directors to deliver scheduled maintenance, emergency repairs, and multi-zone climate control optimizations.
Comprehensive repair and belt replacement for 3-ton to 25-ton commercial rooftop cooling units.
Redundant precision cooling systems to protect critical IT hardware and network equipment from overheating.
Custom maintenance schedules featuring filter changes, belt tension checks, and economizer testing.

Commercial HVAC systems in Los Angeles demand specialized engineering expertise to maintain business continuity, tenant comfort, and Title 24 energy standards:
| Commercial System Type | Tonnage Range | Control Architecture | Common Failure Points | Service Protocol |
|---|---|---|---|---|
| Packaged Rooftop Units (RTU) | 3 to 25 Tons | Economizer & BACnet DDC | Economizer gear failure, belt wear, dirty coils | Title 24 economizer calibration, belt replacement, coil wash. |
| Variable Refrigerant Flow (VRF) | 6 to 50+ Tons | Inverter Modular Control | EEV metering valve fault, communication loop error | Modular diagnostic scan, EEV calibration, oil return check. |
| Commercial Water Chiller Systems | 20 to 200+ Tons | Chilled Water Loop / BAS | Pump impeller wear, flow switch fault, scale buildup | Chiller tube descaling, water flow balancing, sensor audit. |
| Split System Commercial Heat Pumps | 5 to 15 Tons | Dual-Stage Thermostat / BACnet | Contactor arcing, phase loss, high head pressure | Phase monitor testing, dual compressor stage balancing. |
Structured commercial service protocol ensuring minimal business disruption and maximum energy efficiency.
Connecting to BACnet / Modbus controls to analyze fault logs, temperature setpoints, and economizer damper positions.
Checking 208V/230V/460V 3-phase voltage balance, phase monitors, magnetic starters, and compressor RLA amp draws.
Testing outside air economizer dampers, enthalpy sensors, and CO2 indoor air quality demand-controlled ventilation sensors.
Evaluating tandem compressor staging, unloader valves, electronic expansion valves (EEV), and oil level sight glasses.
High-volume chemical pressure washing of multi-row commercial condenser and evaporator coils to restore full heat exchange.
Issuing detailed commercial service reports, updating facility maintenance compliance logs, and verifying tenant comfort levels.
