Chiller inspection form

In short

This chiller inspection form gives a technician a clear order of checks across the refrigerant circuit, condenser and evaporator water side, electrical condition and controls, then a place to log the result. Run it as an inspection template in Cohiva Control and a failed item raises a work order automatically, with versioned, immutable records. Refrigerant and electrical work must be done by licensed, qualified people, following the manufacturer's instructions.

Chiller inspection form

A chiller is one of the larger and more expensive pieces of plant on most sites, and when it goes down the impact is immediate. A structured inspection form keeps a technician working through the same logical checks each time, so early signs of trouble, a fouled condenser, a small refrigerant leak indication, a pump losing flow, are caught before they become a breakdown. This form sets out a sensible order and shows how to run it inside Cohiva Control.

Treat the items as practical guidance. For specific intervals, pressures, temperatures and any measurements, follow the manufacturer’s instructions and any applicable standards.

Before you start

  • Confirm the maintenance window and the effect of any shutdown on the building.
  • Isolate the chiller and apply your site’s lockout procedure before opening panels.
  • Open the asset record in Cohiva Control and confirm the correct chiller is selected.
  • Review faults, alarms and trends since the last inspection.

Check the refrigerant circuit

Refrigerant work must be done by a licensed and qualified person. The checks below are largely observational.

  • Look for signs of refrigerant leaks, oil traces and corrosion around the circuit.
  • Check sight glasses and indicators as fitted, and note their condition.
  • Read suction and discharge values where gauges are present and compare against the normal range.
  • Listen for unusual compressor noise and check for excessive vibration.

Check the water side

  • Inspect the condenser for fouling, scale and corrosion, and clean as required.
  • Check the evaporator side for fouling and flow restriction.
  • Confirm chilled and condenser water pumps run correctly and hold flow.
  • Inspect strainers, valves and visible pipework for leaks and blockages.
  • Read approach and flow values you track, and log them.

Check the electrical condition

Electrical work must be carried out by a licensed and qualified person.

  • Inspect panels, terminals and contactors for heat damage and looseness.
  • Confirm safety controls and interlocks are in place and not bypassed.
  • Check that guards and covers are secure.

Check controls and operation

  • Confirm the chiller responds to its controller and reaches the target.
  • Review setpoints and schedules against the building’s needs.
  • Check and clear alarms, and note any recurring ones for investigation.
  • Log run hours and any meter readings you depreciate against.

Log and close out

  • Mark each item pass or fail.
  • Attach photos of fouling, corrosion or damage.
  • Remove the lockout, return the chiller to service and confirm stable operation.

In Cohiva Control, a failed item can raise a work order automatically, so a fouled condenser or a flagged leak becomes a scheduled job with photos attached. Because inspection records are versioned and immutable once submitted, you build a reliable history per chiller for trend analysis and the asset’s record.

Frequently asked questions

What does a chiller inspection cover?
A typical inspection looks at the refrigerant circuit, the condenser and evaporator water side, pumps and flow, the electrical condition and the controls, plus a general check for leaks, corrosion and noise. Follow the manufacturer's guidance for specifics.
How often should a chiller be inspected?
It depends on the chiller, its duty and your operating season. Follow the manufacturer's schedule and adjust for high-load periods, rather than relying on a generic interval.
Can I run this as a recurring inspection?
Yes. Build it as an inspection template on a preventive maintenance schedule in Cohiva Control so it generates work orders on a time or meter interval and tracks completion.
What happens when an item fails?
A failed item can raise a work order automatically, so a refrigerant leak indication or a fouled condenser becomes a tracked repair. The inspection record is versioned and immutable once submitted.
Who is allowed to work on the chiller?
Any refrigerant handling or electrical work must be carried out by a licensed and qualified person. General visual checks and readings suit a competent technician under safe isolation.
