Common Data Centre Chiller Faults We Repair

Data centre chillers operate under demanding conditions, often providing continuous cooling for servers and other temperature-sensitive equipment. Faults can compromise cooling performance, increase energy consumption and potentially cause costly downtime.

Our engineers investigate and repair a range of mechanical, electrical and refrigeration faults, including:

  • Compressor failures: Diagnosing mechanical and electrical problems affecting chiller operation.

  • Refrigerant leaks: Identifying leaks, repairing affected components and restoring refrigerant system integrity.

  • Condenser and evaporator faults: Addressing heat transfer issues, blockages and deteriorating components.

  • Fan motor failures: Repairing or replacing faulty motors that affect heat rejection.

  • Expansion valve faults: Investigating refrigerant flow and pressure regulation problems.

  • Chilled-water circulation problems: Assessing pumps, valves, pipework and water flow restrictions.

  • Control system faults: Investigating alarms, sensors and operational control issues.

We assess the entire cooling system to identify underlying faults, rather than simply treating the symptoms

Our Data Centre Chiller Repair Process

We take a structured approach to chiller repairs, considering both the technical fault and the operational requirements of your facility.

Fault Diagnosis & System Assessment

Our engineers inspect the affected equipment, reviewing operating conditions, fault codes, temperatures, pressures and relevant electrical components. We also consider connected cooling infrastructure where this may be contributing to the problem.

Repair Planning & Fault Rectification

Once the cause has been identified, we explain the recommended repairs and any operational considerations. Work may involve replacing defective components, repairing refrigerant leaks or resolving mechanical and chilled-water system faults.

Operational Testing & Recommissioning

Following repairs, we carry out appropriate testing to check that the equipment is operating correctly. This may include verifying cooling performance, system pressures, temperature control and associated safety functions before returning the equipment to service.

Emergency Data Centre Chiller Repairs

Unexpected chiller failures can create serious challenges for data centres, particularly where cooling equipment supports high-density server environments or other mission-critical operations.

We provide 24/7 call-out support for urgent cooling faults, helping facilities teams assess breakdowns and determine the appropriate repair requirements.

Where redundant chillers or alternative cooling capacity are available, we consider how repairs can be coordinated to reduce disruption to critical operations. The options depend on the existing system configuration and the nature of the fault.

Repairs for Air-Cooled & Water-Cooled Data Centre Chillers

Different data centre cooling systems require different repair methods. Our experience includes air-cooled and water-cooled chillers, alongside the associated mechanical infrastructure needed to maintain dependable cooling.

We work with commercial chiller equipment and related components, including compressors, heat exchangers, pumps, valves and chilled-water pipework.

As a Geoclima Special Partner, we also have specialist experience with high-efficiency Geoclima chillers, including systems incorporating Turbocor compressor technology.

For facilities requiring wider cooling system support, our data centre air conditioning services cover specialist cooling design, installation and maintenance.

Preventative Maintenance to Reduce Chiller Breakdowns

Regular maintenance helps identify developing faults before they result in unexpected equipment failures.

Our planned maintenance services can include mechanical inspections, refrigerant system checks, electrical testing, control assessments and chilled-water performance reviews, depending on the equipment and its operating requirements.

Routine servicing can also help identify inefficient operation, component deterioration and conditions that may shorten equipment lifespan.

Where an ageing chiller is becoming increasingly unreliable or uneconomical to repair, we can assess replacement options through our chiller installation and projects service.
