Understanding the Importance of Aircon Cleaning

Before delving into the ideal cleaning schedule, let’s grasp why cleaning your aircon is crucial:

1. Efficient Cooling

A clean aircon functions efficiently, providing faster and more effective cooling. Dust and debris accumulation can obstruct airflow, leading to reduced cooling capacity.

2. Energy Savings

Clean aircon units consume less energy. When dust accumulates on the condenser coils, the system has to work harder, consuming more electricity and potentially increasing your utility bills.

3. Improved Air Quality

Dirty aircon filters and vents can harbour allergens, dust mites, and mould, negatively impacting indoor air quality. Regular cleaning helps maintain healthier air for your family.

4. Prolonged Lifespan

A well-maintained aircon lasts longer. Neglecting cleaning can lead to wear and tear, potentially resulting in costly repairs or replacements.

Determining the Cleaning Frequency

Now, let’s address the central question: how often should you clean your aircon? The frequency depends on various factors:

1. Usage

The more you use your aircon, the more frequently it should be cleaned. If it’s running continuously during the summer months, consider cleaning it every 2-3 months.

2. Environment

Living in a dusty environment or near construction sites can accelerate dirt buildup. In such cases, cleaning every 2-3 months is advisable.

3. Allergies and Health Concerns

If you or your family members have allergies or respiratory issues, frequent cleaning (every 1-2 months) is recommended to maintain good indoor air quality.

4. DIY vs. Professional Cleaning

Routine maintenance like cleaning or replacing filters can be done by homeowners. However, professional servicing, including deep cleaning of the entire unit, should be conducted at least once a year.

DIY Aircon Cleaning

Here’s a step-by-step guide for DIY aircon cleaning:

Step 1: Turn Off the Power

Safety first! Before starting, turn off the power supply to the aircon to avoid accidents.

Step 2: Clean the Filters

Remove and clean the air filters. You can use a vacuum cleaner or wash them with mild soap and water. Make sure they are completely dry before reinstalling.

Step 3: Clean the Vents and Coils

Using a soft brush or a vacuum cleaner, carefully remove dust and debris from the vents and coils. Be gentle to avoid damaging any components.

Step 4: Inspect the Drainage System

Check the condensate drain for clogs. A clogged drain can lead to water leakage. Clear any blockages if necessary.

Step 5: Reassemble and Test

After cleaning, reassemble the unit, turn on the power, and check if it’s running smoothly.


Regular aircon cleaning is essential for efficient cooling, energy savings, improved air quality, and a longer lifespan. The cleaning frequency depends on usage, environment, health concerns, and the type of maintenance required. Whether you opt for DIY cleaning or professional servicing, don’t neglect this crucial aspect of aircon maintenance.
