A model-specific approach

What an inspection considers.

Assess the cause

Follow the evidence.

Locate the noise and inspect mountings, cabinet contact, blower, fan and compressor operating conditions.

The exact model and operating conditions determine which tests apply. These are possible inspection directions, not a list of components that must be changed.

Before the appointment

Keep the useful details.

Record the sound from a safe position and say whether it comes from the indoor or outdoor unit.

Record the timing, previous work and accessible model label. Do not remove covers or handle live, refrigerant or pressurised components to obtain information.

Completion

What to check after the work.

Recheck the affected operating stage and compare the original noise after the approved work.

Discuss which operation was checked and what to observe during normal use. Keep the service date, model and work description if you need to report the symptom again.
