Photograph the starting condition
With the system switched off, photograph the front cover, removable filter, louvres and any visible buildup or water staining. Keep the images with the condition report.
Test normal operation
Record whether the system starts, moves air normally and shows any obvious leak, unusual noise or persistent odour. Do not dismantle the indoor head during a tenancy check.
Separate cleaning from repair
A dirty filter or accessible buildup may require maintenance or cleaning. Fault codes, electrical problems, refrigerant issues and installation faults need an appropriately qualified technician.
The practical takeaway
Clear photos and a simple operating check make rental air-con responsibilities easier to discuss and quote.
