Singapore’s warm and humid climate means air conditioners work almost every day. Over time, dust, dirt, and moisture build up inside the unit, reducing cooling performance and increasing electricity consumption.

The good news is that homeowners can safely perform some basic aircon maintenance to keep their units cleaner between professional servicing appointments.

In this guide, Mr Butler Home Services shares practical DIY aircon cleaning tips while introducing some of the essential maintenance tools available from DADE Hardware.

Why Regular Aircon Cleaning Matters

A dirty air conditioner doesn’t just cool less efficiently—it can also affect indoor air quality and shorten the lifespan of your unit.

Regular maintenance helps:

• Improve cooling performance
• Reduce electricity bills
• Remove accumulated dust
• Minimize unpleasant odours
• Extend the life of the air conditioner
• Improve indoor air quality

While homeowners can handle simple cleaning tasks, deeper cleaning should always be carried out by trained technicians.

Tools You’ll Need

Before you begin, prepare a few simple tools.

Cleaning Tools

• Microfiber cloth
• Soft cleaning brush
• Vacuum cleaner with brush attachment
• Spray bottle with clean water
• Mild detergent
• Protective gloves

Helpful Hardware

• Step ladder
• Flashlight
• Screwdriver (only if your manual recommends removing the cover)
• Air conditioner cleaning bag (optional)

Many of these household maintenance tools are available from DADE Hardware, making routine aircon care more convenient and safer.

Step 1: Turn Off the Power

Safety always comes first.

Before touching any part of your air conditioner:

• Switch off the unit.
• Turn off the power supply at the isolator if possible.
• Wait a few minutes before cleaning.

Never clean electrical components while power is connected.

Step 2: Clean the Air Filters

The air filter is the easiest and most important part to clean.

Open the front panel according to your manufacturer’s instructions and remove the filters.

Then:

• Vacuum loose dust.
• Wash with clean water.
• Use mild soap if necessary.
• Allow the filters to dry completely before reinstalling.

Cleaning the filters every two to four weeks can significantly improve airflow.

Step 3: Wipe the Front Panel

Dust often collects on the exterior surfaces.

Use a damp microfiber cloth to clean:

• Front cover
• Air outlet
• Air louvers
• Display panel

Avoid using harsh chemicals that may damage the plastic surface.

Step 4: Vacuum Visible Dust

Using a vacuum cleaner with a soft brush attachment, carefully remove visible dust around:

• Air intake
• Front vents
• Accessible surfaces

Do not insert the vacuum deep inside the unit.

Step 5: Keep the Outdoor Unit Clean

The outdoor condenser also needs attention.

Remove:

• Leaves
• Dust
• Plastic bags
• Debris
• Grass

Ensure there is adequate space around the outdoor unit for proper airflow.

Do not spray high-pressure water directly onto the condenser fins.

What You Should NOT DIY

Some cleaning procedures require specialised equipment and technical knowledge.

Avoid attempting to:

• Remove the blower wheel
• Wash the evaporator coil with high-pressure equipment
• Disassemble electrical components
• Handle refrigerant pipes
• Perform chemical cleaning
• Pressure wash the indoor unit

Improper cleaning can damage the system or void the manufacturer’s warranty.

When Should You Call a Professional?

DIY cleaning helps with routine maintenance, but professional servicing is recommended if you notice:

• Weak cooling
• Water leakage
• Loud noises
• Bad odours
• Ice forming on the unit
• High electricity bills
• The unit has not been serviced for several months

Professional technicians have the proper equipment to clean internal components safely and thoroughly.
