Our mission is healthy air for a healthy life. That means restoring cooling reliability while improving indoor air quality, energy efficiency, and occupant comfort—especially during peak Los Angeles heat.

Our Diagnostic Process

We begin with a structured assessment that minimizes downtime and pinpoints the root cause. Expect methodical checks—not trial and error.

• Operational review: alarms, trends, short‑cycling, and sequence of operations
• Refrigerant circuit analysis: superheat, subcooling, charge balance, and leak detection
• Compressor health: electrical, mechanical, oil condition, and vibration indicators
• Heat exchange: condenser/evaporator approach temperatures, tube fouling, airflow/waterflow
• Controls & VFDs: sensor calibration, setpoints, safeties, network communication
• Power quality: voltage, phase balance, harmonics that impact reliability

You receive a clear findings report with prioritized actions—what’s urgent, what’s preventive, and what will improve efficiency and extend equipment life.

Repairs We Perform on York Chillers

• Refrigerant leak detection, repair, evacuation, and precise recharging
• Compressor repairs for centrifugal, screw, and scroll units
• Oil system service, gasket and seal replacement, and oil analysis
• Condenser/evaporator cleaning, tube descaling, and approach temperature recovery
• Sensor and control board replacement, VFD tuning, and reset of safeties
• Water flow corrections: pump/valve issues, strainers, and balancing
• Electrical repairs: contactors, relays, capacitors, and wiring integrity

Every repair is executed with attention to long‑term stability—reducing nuisance trips, improving IPLV/NPLV performance, and safeguarding your utility spend.

Preventive Maintenance Program

The most affordable repair is the one you prevent. Our tailored PM plans keep York chillers reliable through summer peaks and shoulder seasons.

• Seasonal start‑up and shutdown procedures
• Condenser coil/tube cleaning and water treatment coordination
• Setpoint optimization and staging/lead‑lag strategy
• Oil sampling, filter changes, and bearing checks
• Controls calibration, trends review, and alarm rationalization
• Emergency spares strategy to reduce MTTR

We align maintenance with ASHRAE best practices and local codes to protect compliance and warranty requirements while minimizing disruption to your operations.

Retrofits & Energy Optimization

When repair isn’t enough, we upgrade for performance. Our engineers recommend data‑driven improvements that typically pay back through energy and reliability gains.

• ECM/VFD integration for pumps and condenser fans
• Advanced controls, demand limiting, and reset strategies
• Heat exchanger enhancements and approach temperature restoration
• Sensor upgrades for tighter control and trending visibility
• Plant sequencing to match part‑load profiles

We also coordinate with your building automation provider for smooth integration, trend logging, and performance validation. The result: steadier supply temperatures, reduced peak demand, and lower life‑cycle cost.

Emergency Response When It Matters

In a critical environment—healthcare, data rooms, labs—every minute counts. Our rapid‑response team stabilizes systems, isolates faults, and implements safe, temporary cooling measures when needed to protect people, equipment, and inventory.

From nuisance trips and high‑head pressure to oil return problems and control failures, we restore capacity quickly and verify performance before we leave—so your facility returns to normal with confidence.
