Where each walk sits in the schedule

  1. 01quarterly

    Chiller quarterly maintenance checklist

    Every quarter, with readings taken under load so the numbers mean something, not at standby.

    Run by: The chiller service tech on the contracted quarterly visit.

  2. 02annual

    Chiller annual maintenance checklist

    Once a year, scheduled in the off-season so the machine can be opened, tested and down without load impact.

    Run by: The chiller manufacturer's or specialist service technician.

What most often fails on a chiller

  • Readings logged from the display without comparing them to what the sensors should be saying.
  • Approach temperatures creeping up quarter over quarter with no one trending the log.
  • Refrigerant sight glass checked for presence of flow, not for moisture indication.
  • Tubes punched without an eddy-current or condition record, so pitting is discovered as a leak.
  • Oil analysis skipped because the oil 'looked clean.' The lab catches what the eye can't.
  • Safety trip setpoints drift-checked on paper but never actually tripped during the test.

Verified against

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
