Date: 27 April 2026
Service Type: Routine Maintenance & Chemical Coil Cleaning
Equipment: Ceiling-Mounted Fan Coil Unit (FCU) / Cassette Unit
Disassembly: Removed external housing, air intake grilles, and drain pan for detailed inspection.
Filter Servicing: Extracted primary air filters showing significant dust accumulation. Filters are slated for high-pressure washing.
Coil Inspection: Internal evaporator coils inspected; visible residue and biofilm identified on fins, requiring a chemical wash to restore heat exchange efficiency.
Drainage Check: Clearings of the condensate tray and internal panels to prevent water leakage and fungal growth.
The accumulation of particulates on the mesh filters and moisture on the cooling fins indicates the unit is due for its scheduled chemical treatment to maintain optimal airflow and indoor air quality (IAQ).
