What Our Chiller AC Maintenance and Repair Includes

Preventive Chiller Maintenance

Stay ahead of failures with a checklist built around your system’s tonnage, design, and duty cycle:

• Condenser coil cleaning and fin straightening
• Evaporator coil care and airflow verification
• Condenser tube brushing and chemical descaling where applicable
• Strainer and filter cleaning or replacement
• Belt inspection, pulley alignment, and bearing lubrication
• Electrical panel tightening, contactor inspection, and megger tests
• Sensor and control calibration, setpoint verification
• Refrigerant charge check, superheat/subcool measurement
• Leak detection via electronic sniffers and nitrogen pressure tests
• Drain line flushing and pan treatment
• Operating log with approach temperatures and delta-T verification

Expert Chiller Repair and Troubleshooting

When performance drops or alarms appear, we find the root cause and fix it right:

• Compressor issues: hard starts, short cycling, overheating
• High head pressure, low suction pressure, low capacity
• Expansion valve and EEV faults, blocked driers, oil return problems
• VFD and soft-starter faults, sensor and actuator failures
• Control board and BMS communication errors
• Component replacement: compressors, contactors, capacitors, sensors, valves, pumps, fan motors

Energy Efficiency Tuning and Optimization

Lower your cooling cost without compromising comfort or process requirements:

• Chilled water and condenser water reset strategies
• Lead–lag sequencing and staging optimization
• VFD tuning for pumps and fans
• Evaporator and condenser approach temperature improvement
• Heat exchanger performance checks and water treatment alignment
• BMS optimization with actionable setpoints and alarms

Water Treatment and Condenser Care

For water-cooled systems, we manage scale, corrosion, and biofouling to protect capacity and efficiency:

• Water chemistry testing and dosing recommendations
• Tube cleaning and descaling
• Cooling tower hygiene guidance and inspection
• Corrosion monitoring and inhibitor optimization

Controls, BMS, and Calibration

• Sensor calibration and replacement
• Control logic review and setpoint optimization
• Alarm mapping and BMS integration support
• Trending setup to monitor performance indicators over time

Emergency Call-Outs

Rapid response for critical breakdowns to minimize downtime and protect equipment. Temporary workarounds and staged repairs offered where possible.

Annual Maintenance Contracts (AMC)

Predictable costs and priority service with a plan tailored to your site:

• Planned visits with seasonal checks
• Performance audits and energy reports
• Inclusive or partial spare parts options
• Guaranteed response times according to your SLA

Our Process

1. Discovery and Site Survey
   We review system drawings, current operating issues, and service history. A technician inspects plant condition, access, and safety requirements.
2. Diagnostic Report and Quote
   You get a clear scope with findings, photos where relevant, parts list, timelines, and a transparent cost breakdown.
3. Maintenance or Repair Execution
   We follow documented procedures, protect work areas, and log all readings before and after service.
4. Testing and Commissioning
   We verify stability under load, confirm approach temperatures and delta-T, and clear any alarms.
5. Handover and Documentation
   Receive a service report, recommendations, and a preventive care plan to keep performance on track.
6. Ongoing Support
   Optional AMC, periodic audits, and remote assistance for control issues or alarms.
