Daikin aircon water leaking
Aircon water leaking is one of the most common issues faced by homeowners and businesses in Singapore. While a small amount of condensation is normal, water dripping continuously from your air conditioner is a clear sign that something is wrong. If left unchecked, it can lead to water damage, mould growth, foul smells, and reduced cooling performance. Understanding the causes of aircon leaks and knowing when to call a professional like SGaircon and Services can help you prevent bigger and more costly problems.
Why Is Your Aircon Leaking Water?
To understand why leaks happen, it’s important to know how an air conditioner works. During cooling, moisture in the air condenses on the evaporator coil and flows into a drainage tray before exiting through the drainpipe. If any part of this process is disrupted, leaks can start.

1. A Choked or Blocked Drainpipe
A clogged drainpipe is the number one reason for aircon leaks. Dirt, dust, algae, or mould can build up inside the pipe, preventing water from flowing out. When the pipe is blocked, the water backs up and starts dripping inside your home.
This issue is especially common in Singapore due to high humidity, which encourages mould growth in the drainage system.
Signs:
- Water dripping from the indoor unit
- Gurgling or bubbling sounds
- Visible water pooling below the aircon
Regular maintenance from SGaircon and Services helps prevent choked drainpipes through proper vacuuming and flushing.
2. A Dirty or Frozen Evaporator Coil
When the evaporator coil gets too dirty, airflow is restricted. This causes the coil to freeze. When the ice eventually melts, the excess water overflows, causing leakage.
Singapore’s dusty environment and everyday usage make dirty coils a common issue, especially if servicing is neglected.
Signs:
- Weak cooling
- Ice forming on the coil
- Water dripping after the aircon is switched off
A chemical wash or deep cleaning by a professional technician is often required to fix this problem.
3. A Damaged or Rusted Drain Pan
Over time, the drain pan can develop cracks or rust, especially in older aircon units. When the pan cannot hold water properly, leakage will occur.
Signs:
- Water is dripping even when the aircon is newly serviced
- Visible rust or cracks
If this happens, the drain pan must be replaced by a qualified technician.
4. Low Refrigerant (Gas)
Low refrigerant levels can cause the evaporator coil to freeze. As the ice melts, water starts dripping. Gas leaks happen due to poor installation, wear and tear, or damaged piping.
Signs:
- Poor cooling performance
- The compressor is frequently turning on and off
- Hissing noises near the aircon
SGaircon and Services can perform a refrigerant check and top-up if needed, ensuring your system cools efficiently again.
5. Poor Installation or Improper Tilt
An aircon unit that is not properly tilted will cause water to drip inside instead of flowing out through the drainpipe. This is common in newly installed units or after renovations, where the unit may have shifted.
Signs:
- Water dripping soon after installation
- The aircon unit is visibly not level
This can be easily corrected by a professional reinstallation or alignment.
When Should You Call a Technician?
While small issues like minor condensation can be normal, consistent water leakage must be addressed quickly. Here’s when you should call SGaircon and Services:
1. Leakage Lasts More Than 24 Hours
If water continues dripping for more than a day, there is likely a blockage, frozen coil, or internal damage.
2. You Notice Water Marks or Ceiling Stains
If your aircon is mounted high on the wall or ceiling, water leaking can lead to structural damage. Water stains mean the issue is already serious and requires immediate attention.
3. The Aircon Suddenly Stops Cooling
When leaks occur together with weak cooling, it’s a sign of dirty coils or low refrigerant—both require professional servicing.
4. You Hear Unusual Sounds
Gurgling, bubbling, or hissing sounds indicate drainage issues or refrigerant leaks. Avoid turning the aircon on until a technician checks it.
5. Mouldy or Musty Smell from the Aircon
A leaking unit often creates a damp environment perfect for mould growth. This can affect your indoor air quality and health. View more
