Prepare before the heat

Is your air conditioner ready for spring and summer?

A short pre-season check can reveal overdue maintenance before the system is needed every day.

The short answer: Inspect filters, accessible internal areas, startup odour, airflow, noise and drainage before extreme weather arrives.

What can you check in five minutes?

Use accessible observations and keep the unit off while handling filters.

  1. 01
    Inspect the filters

    Check for heavy dust, moisture and correct fitting.

  2. 02
    Look through the louvres

    Use a torch to check accessible fan and internal areas.

  3. 03
    Start the system

    Notice unusual odour, noise or delayed operation.

  4. 04
    Check airflow

    Compare airflow without placing hands inside the unit.

  5. 05
    Look for water

    Note visible leaks, staining or drainage concerns.

Routine maintenance

What can the owner usually handle?

Simple filter care is useful, but it is not a complete internal clean.

Filter washing

Wash user-serviceable filters according to manufacturer guidance, dry them and refit correctly.

Clear the immediate area

Keep curtains, furniture and obvious obstructions away from airflow.

Record changes

Note odour, noise, airflow and visible buildup so changes are easy to explain.

Before frequent use

When is professional help worthwhile?

Act before an extreme-weather period when maintenance or faults are already visible.

Professional cleaning may be relevant

  • Visible internal buildup.
  • Dirty filters plus neglected internal components.
  • Stale startup odour with contamination.
  • Long period since professional cleaning.

Technical assessment is important

  • Error codes or repeated tripping.
  • Burning smell or electrical concern.
  • Persistent leak or damaged part.
  • Sudden loss of cooling or heating.

Professional preparation

What does a pre-season deep clean include?

The internal airflow path is cleaned, the accessible drainage path is maintained and the system is checked after reassembly.

  1. 01
    Controlled access

    The indoor unit is opened and disassembled as required so cleaning reaches beyond the visible surface.

  2. 02
    Filters and covers

    Removable filters and covers are taken out, professionally washed, dried and correctly refitted.

  3. 03
    Coil and fan barrel

    The indoor coil and rotating fan barrel are deep cleaned using controlled containment.

  4. 04
    Cleaning treatment

    Air-conditioner-safe cleaning and sanitising products are used according to the service method.

  5. 05
    Drainage check

    The drain pan is cleaned and the accessible drain is checked and flushed.

  6. 06
    Reassembly and test

    The system is reassembled, operated and checked before the service is completed.

Quick answers

Questions people ask before contacting MACC

Should I wait until the first very hot day?

No. Earlier inspection gives more time to address maintenance or faults before demand increases.

Are clean filters enough for summer preparation?

They are important, but internal components behind the filters can still hold buildup.

Can cleaning guarantee better cooling?

No. Cleaning addresses accessible buildup; technical faults require assessment.

What information should I provide?
