Aircon servicing

When it comes to keeping your AC system running efficiently, professional servicing is essential. However, regular maintenance in between those professional checkups can significantly extend your aircon’s lifespan, improve energy efficiency, and ensure your indoor air quality remains high.

At COOLCARE AIRCON, we believe that informed customers can play a big role in prolonging the performance of their cooling systems. In this article, we’ll walk you through practical steps you can take to maintain your aircon between professional servicing sessions.

Why In-Between Maintenance Matters

Even if you schedule regular professional servicing, neglecting your aircon in between visits can lead to:

  • Higher electricity bills

  • Reduced cooling efficiency

  • Foul odours

  • Shortened unit lifespan

  • Unnecessary breakdowns

Taking the time to perform some simple maintenance tasks can prevent these issues and keep your AC running like new.

1. Clean or Replace Air Filters Regularly

One of the simplest yet most impactful things you can do is clean or replace the air filters. Dirty filters obstruct airflow, making your aircon work harder and consume more energy.

How Often?
  • Every 2–4 weeks if you use the aircon daily.

  • More frequently if you have pets, allergies, or live in a dusty environment.

How to Do It:
  • Turn off the AC and open the front panel.

  • Remove the filter and wash it with lukewarm water.

  • Let it dry completely before reinstalling.

  • For non-washable filters, replace them with a new one.

2. Keep the Outdoor Unit Clean

The outdoor unit (condenser) is often overlooked, but it plays a critical role in the heat exchange process. Dirt, leaves, and debris can block the airflow and reduce efficiency.

  • Inspect the unit monthly.

  • Use a soft brush or a garden hose to remove debris (make sure the unit is turned off).

  • Trim back plants and vegetation to maintain at least 2 feet of clearance around the unit.

3. Check for Obstructions Around the Indoor Unit

Ensure that nothing is blocking the indoor unit’s vents. Furniture, curtains, or wall hangings that obstruct airflow can reduce cooling performance and create uneven room temperatures.

What You Can Do:
  • Keep the surrounding area clutter-free.

  • Avoid placing electronics or heat-generating appliances near the unit.

4. Inspect the Aircon for Leaks or Unusual Sounds

Keep an eye (and ear) out for any signs that something might be wrong. Water dripping, rattling sounds, or a musty smell may indicate a problem that needs professional attention.

Red Flags to Watch For:
  • Water stains on the wall or floor

  • Ice buildup on the coils

  • Odd smells or loud noises

  • Reduced airflow or cooling

If you notice any of these, it’s time to call COOLCARE AIRCON for a full inspection.

5. Use a Timer or Thermostat Wisely

Running your AC constantly can wear it out faster and spike your electricity bill. A smart or programmable thermostat helps regulate temperatures and reduce unnecessary use.

Smart Practices:
  • Set your aircon to a moderate temperature (around 24–26°C).

  • Use the timer function to avoid overnight operation.

  • Turn off the unit when the room is not in use.

The fan mode helps dry out the internal components, especially the coils and fan blades. This prevents mold and mildew buildup, which can cause bad odours and reduce air quality.

Tip:
  • Run fan mode for 15–30 minutes after cooling to remove excess moisture.

7. Check and Clean the Drain Pipe

The drain pipe can become clogged with dust, algae, or mold, causing water leakage and even water damage to your walls or floors.

Maintenance Guide:
  • Locate the drain pipe (usually a PVC pipe).

  • Flush it with a mixture of water and vinegar to prevent blockages.

  • If water isn’t draining properly, contact a technician for a deeper clean.

8. Protect the Unit During Off-Season

If you're not using the AC for a while (like during cooler months), take steps to protect it:

  • Cover the outdoor unit to prevent dust buildup.

  • Clean both indoor and outdoor units before switching off.

  • Unplug the system if it's not going to be used for an extended period.

When to Call a Professional

While regular DIY maintenance is important, it can’t replace professional AC servicing. At COOLCARE AIRCON, we recommend a professional service at least once or twice a year, depending on usage.

Our expert technicians will:

  • Clean coils and components thoroughly

  • Check refrigerant levels

  • Inspect electrical systems

  • Detect potential issues before they become costly repairs

Final Thoughts

Proper maintenance between professional aircon services isn’t difficult—it just requires consistency. By taking a few minutes every month to inspect, clean, and adjust your unit, you can enjoy better cooling performance, cleaner air, and lower energy bills.
