Air Conditioning Systems

In hot, humid climates, air conditioning often runs for long hours. Keeping it clean helps maintain airflow, cooling performance and reliable drainage.

🧼 Air filters: about every two weeks

For a split system used daily, checking and cleaning the washable filters every two weeks is a good starting point. Dusty rooms, pets or heavy use may mean they need attention sooner.

Follow your unit’s instructions—some specialty filters aren’t washable.

🔧 Internal cleaning: depends on use and condition

Clean filters don’t necessarily mean a clean unit. Dirt can also build up on the indoor coil, blower wheel, drain tray and drain pipe.

For units working hard in tropical conditions, a professional inspection every 3–6 months is a practical starting point. Cleaning frequency should depend on the condition of the unit and the manufacturer’s recommendations.

⚠️ Don’t wait for the next service if you notice:

• Musty or unpleasant smells

• Water dripping indoors

• Weak airflow

• Visible dirt or mould

• Reduced cooling or ice forming

These symptoms need investigation—cleaning alone may not fix the cause.

✅ A few simple tips

• Switch off and isolate the power before cleaning.

• Only wash filters designed to be washed, and dry them fully before refitting.

• Keep leaves and debris clear of the outdoor unit.

• Have persistent smells or drainage problems checked professionally.

What’s your experience?

If you live or work in a humid climate, how often do you clean your aircon? Have you found the filters stay clean while the blower wheel gets dirty?
