Step one
How is the room and system prepared?
Preparation protects the property and gives the technician controlled access.

What happens during a professional air-conditioner deep clean?
A proper deep clean is a controlled service process, not a quick filter wash.
The short answer: The technician protects the work area, opens the indoor unit, cleans the filters, coil, fan barrel and drainage components, then reassembles and test runs the system.

The internal work
Which components are professionally cleaned?
The value is in reaching the components behind the filters.
- 01Controlled access
The indoor unit is opened and disassembled as required so cleaning reaches beyond the visible surface.
- 02Filters and covers
Removable filters and covers are taken out, professionally washed, dried and correctly refitted.
- 03Coil and fan barrel
The indoor coil and rotating fan barrel are deep cleaned using controlled containment.
- 04Cleaning treatment
Air-conditioner-safe cleaning and sanitising products are used according to the service method.
- 05Drainage check
The drain pan is cleaned and the accessible drain is checked and flushed.
- 06Reassembly and test
The system is reassembled, operated and checked before the service is completed.
Cleaning has boundaries
What cannot be solved by cleaning alone?
A responsible service separates cleaning from repair and diagnostic work.
The clean is designed for
- Accessible contamination and grime.
- Filters, covers, indoor coil and fan barrel.
- Drain pan and accessible drain maintenance.
- Reassembly and post-clean operation check.
A technician assessment is required for
- Electrical faults and repeated tripping.
- Refrigerant loss or pressure concerns.
- Broken components or error codes.
- Leaks or faults beyond accessible cleaning work.
Completion evidence
What should completion look like?
The unit should be visibly reassembled, operated and checked before the technician leaves.
Before condition
Document what is visible without claiming every system is identical.
Professional process
Show access, containment, internal cleaning and reassembly.
Completion
Operate and check the system after the listed work is complete.

Quick answers
Questions people ask before contacting MACC
Why is a containment bag used?
It helps control wash water and protects the room while internal components are cleaned.
Are the filters the main part of the clean?
No. Filters are only one part. The indoor coil, fan barrel and drainage path are central to a deep clean.
Is the system tested afterwards?
Yes. Reassembly and a final operation check are part of the professional process.
Does this process include repair work?
No. Repair, electrical and refrigeration work are assessed separately when required.
