How to Fix an Aircon Leaking Water Outside in Singapore

You can fix an aircon leaking water with proper guidance and tools. An aircon is a necessity in Singapore’s warm and humid climate. They are actually designed to remove moisture from indoor air, excessive water leaking from the outdoor unit may indicate a problem.

Understanding the cause and timely addressing it can prevent further damage and restore your aircon’s efficiency. In this article, we’ll explore common reasons for water leaks and how to fix them effectively.

Why Is Your Aircon Leaking Water Outside?

Before you fix an aircon leaking water in Singapore, it is crucial to know the root cause. Some amount of water dripping from the outdoor unit is normal as it’s part of the cooling process. However, if you notice your air conditioner leaking water consistently, it could signal issues.

The issues include a clogged drain pipe, low refrigerant levels and damaged components. Now, let’s look at how you can troubleshoot and fix an AC leaking water.

1. Turn Off the Aircon

Before attempting any fixes, always turn off the aircon and disconnect the power supply. This ensures your safety and prevents further damage to the system during troubleshooting.

2. Check the Drainage System

A clogged drain pipe is one of the most common causes of water leaks. Here’s how you can address it:

  • Locate the drainage pipe and inspect it for visible blockages.
  • Use a vacuum or a long, flexible brush to remove debris.
  • Flush the pipe with clean water to ensure it’s clear.

If the above process does not work, you may need professional assistance to clean the drainage system thoroughly.

3. Inspect the Refrigerant Levels

Low refrigerant levels can cause the evaporator coil to freeze. As a result, when the ice melts, it produces excess water that leaks outside. Signs of low refrigerant can be poor cooling performance and hissing or bubbling noises originating from the aircon unit.

Refrigerant handling requires expertise. Therefore, it is not recommended to adopt DIY for this, rather, contact a certified technician to check and refill the refrigerant.

4. Examine the Outdoor Unit

The outdoor unit may leak water due to a possible blockage or damage to its vents or other components.  Clean the area around the unit and ensure the condenser coils are free from dust.

Tighten or repair any loose components that could affect drainage. If the problem persists, contact a professional like LS Aircon Servicing Singapore. 

5. Check the Aircon’s Tilt

If the outdoor unit isn’t properly levelled, water can pool around and leak instead of draining away. Use a spirit level to ensure the unit is installed at the correct angle.

Adjust the positioning by modifying the mounting brackets or support base. However, the adjustment is also a professional task that should be done by a technician to ensure proper alignment. 

6. Monitor Humidity Levels

High humidity levels can sometimes strain the drainage system.  This issue causes more water to leak outside. Using a dehumidifier or setting the aircon to a lower fan speed can reduce the moisture output.

7. Call a Professional Technician

If you’ve tried the steps above and the problem persists, it’s time to call a professional technician. They can diagnose and rectify complex internal issues and provide thorough cleaning of the aircon system to remove the debris from all parts of the aircon unit. Moreover, they can also repair and replace the aircon components if needed. 

Conclusion

It can be a simple DIY task to fix an aircon leaking water if you are equipped with the right guidance. An aircon leaking water outside can be inconvenient and may signal underlying problems. By following these steps, you can resolve many common issues. However, dealing the refrigerant and complex internal faults is the job of a licensed technician. 

Frequently Asked Questions

An air conditioner leaking water may be due to a condensate pump failure. This doesn't mean the condensate pump is always causing the issue. But, it can mean a drainage issue is causing water accumulation to spill over. If the pump cannot drain water, manually empty the drain pan to see if there is a problem over there.
Check the drain tube from the condensate collection pan outlet. It's usually a PVC pipe located below the coolant line connections. Moreover, disconnect the drain tube from the collection pan and use a vacuum to suck up the remaining water coming out of the drain. If there is a severe issue, you may call a professional to assist you.
In the absence of appropriate treatment, water is not good for drinking. Boiling and filtering AC water can make it suitable for consumption though. However, you should only drink this water even after filtration, when it is necessary.
