Aircon Servicing

In Singapore’s hot and humid climate, an air conditioner isn’t a luxury—it’s a necessity. To ensure it performs efficiently and keeps energy bills low, regular maintenance is crucial. A common question many homeowners and even business owners ask is: Can I clean the aircon myself?

The short answer is yes—for basic aircon cleaning tasks. However, there are limits to DIY maintenance, and for deep cleaning or technical servicing, it's always best to call in the experts. At LetsCool Aircon and Services, we encourage our customers to take small, safe steps to maintain their units between professional servicing sessions. Let’s explore what you can do yourself, what should be left to professionals, and why regular aircon cleaning matters in the first place. View more.

Why Clean Your Aircon Regularly?

Before diving into DIY versus professional cleaning, it's important to understand why aircon maintenance is essential:

  • Improves cooling performance

  • Reduces electricity consumption

  • Prevents mould and bacteria growth

  • Avoids costly repairs

  • Extends the unit’s lifespan

In a place like Singapore, where air conditioners are used almost daily, dust, dirt, and humidity build up quickly. This leads to clogged filters, dirty coils, and even water leaks if the drainage pipe is blocked.

What Aircon Cleaning Tasks Can You Do Yourself?

As a homeowner, you can safely perform basic cleaning of certain parts of your aircon. Here’s a breakdown of DIY tasks that you can carry out regularly:

1. Clean the Air Filters

The air filters trap dust and particles from the air. When they get clogged, airflow is restricted, forcing your aircon to work harder.

Steps:

  • Turn off and unplug the unit.

  • Open the front panel and remove the filters.

  • Wash them gently with warm water and mild detergent.

  • Let them dry completely before reinstalling.

Frequency: Every 2–4 weeks, depending on usage and indoor air quality.

2. Wipe the Exterior

Keep the outer body of the indoor unit clean by wiping it with a soft cloth. Avoid using harsh chemicals.

3. Vacuum the Louvres

The horizontal blades or louvres can collect dust. Gently vacuum them or wipe them down.

4. Check for Obstructions Around the Outdoor Unit

If your aircon has an outdoor condenser unit, make sure it’s clear of leaves, debris, or any obstructions. This ensures better heat dissipation.

What Should Be Left to Professionals?

While basic cleaning is safe for DIY, deep cleaning and servicing should always be handled by trained technicians like those at LetsCool Aircon and Services. Here’s why:

1. Chemical Cleaning and Overhaul

Over time, dirt, mould, and grime build up deep inside the coils and blower components. A chemical wash uses special cleaning solutions to remove hardened deposits. A chemical overhaul goes even deeper, dismantling key components for a full flush.

These procedures require technical expertise and the right tools—doing them without proper training can damage your unit or pose electrical hazards.

2. Drainage Pipe Cleaning

Clogged drain pipes can lead to water leaks and mould growth. Professionals use vacuum pumps and flushing techniques to thoroughly clean these components.

3. Refrigerant Top-Up and Leak Detection

If your aircon isn’t cooling well, it might need a gas top-up or have a refrigerant leak. Only licensed technicians can handle refrigerants safely and check for leaks using proper gauges.

4. Electrical and Sensor Checks

Faulty sensors, loose wiring, or burnt components can only be diagnosed and fixed by professionals. Attempting electrical repairs without training is highly dangerous.

Risks of DIY Aircon Cleaning

While some maintenance tasks are safe, trying to do too much can be risky:

  • Electrical hazards: Opening the wrong panel or cleaning without turning off the power can lead to shocks.

  • Damage to delicate parts: Aircon components like the evaporator coil or PCB board are sensitive and expensive to replace.

  • Voiding warranty: Tampering with internal parts may void your warranty.

  • Incomplete cleaning: DIY cleaning only covers surface-level dirt; the internal grime requires specialized tools.
