Aircon Leaking Water
Have you ever noticed your air conditioner dripping water inside your home? It’s a common issue faced by many homeowners in Singapore, where the hot and humid weather keeps air conditioners running almost all year round. While a few drops of water might not seem like a big deal, persistent indoor leakage can signal a more serious problem. Understanding why your aircon is dripping water indoors can help you take the right steps before it leads to costly repairs or damage.

1. Condensation and How It Works
To understand aircon leaks, it’s ...
... important to know how condensation works. Your air conditioner cools warm air by passing it over cold evaporator coils. This process causes moisture in the air to condense into water droplets, which are then directed outside through a drainage system.
When everything functions properly, the water exits through a drain pipe. However, when something goes wrong in this process, the water can start dripping inside your room — usually from the indoor unit.
2. Common Causes of Indoor Aircon Water Leakage
There are several reasons why your air conditioner might be dripping water indoors. Let’s explore the most common ones:
a. Clogged Drainage Pipe
This is one of the most frequent causes of aircon water leaks. Over time, dust, dirt, or even algae can build up inside the drainpipe, blocking the flow of water. When the drainage line is blocked, the water has nowhere to go and starts backing up, eventually leaking from the indoor unit.

Regular servicing from a reliable provider like Letscool Aircon and Services can help clear these blockages and prevent future leaks.
b. Dirty or Frozen Evaporator Coils
When the evaporator coil is covered with dust or grime, it can freeze due to restricted airflow. Once the ice melts, it produces excessive water that may overflow from the drain pan. This usually happens when your aircon hasn’t been serviced for a long time.
Professional cleaning and chemical wash services ensure the coils stay clean, improving cooling efficiency and preventing leaks.

c. Improper Installation
If your aircon was installed incorrectly — such as the drainage pipe being at the wrong angle or not sealed properly — it can cause water to leak inside the room.
At Letscool Aircon and Services, our experienced technicians follow a precise installation process, ensuring proper alignment and drainage to avoid such issues.

d. Full or Damaged Drain Pan
The drain pan collects condensation before directing it through the pipe. Over time, the pan may become full, rusty, or cracked, leading to water leakage.
Aircon Repair
If your aircon is older, replacing the pan may be necessary to prevent further damage.
e. Low Refrigerant Levels
Low refrigerant can cause the evaporator coils to become too cold, resulting in ice formation. When the ice melts, it produces excess water that the drain pan cannot handle.
This issue should only be handled by trained professionals, as refrigerant handling requires expertise and specialized tools.

3. Why You Should Not Ignore Aircon Water Leakage
Many people assume that water dripping from their aircon is harmless, but ignoring it can lead to several serious consequences:
Water damage to walls, furniture, and electrical fixtures

Mould and mildew growth that can affect indoor air quality

Reduced aircon performance and energy efficiency

Increased repair costs if minor issues are left untreated

Regular servicing and inspections can prevent these problems and extend your air conditioner’s lifespan.
4. How to Fix or Prevent Indoor Aircon Leaks
While some simple maintenance tasks can be done at home, most aircon water leak issues require professional expertise. Here’s how you can prevent or fix them:
a. Schedule Regular Servicing
Regular maintenance is the most effective way to prevent leaks. Professional technicians will clean the filters, flush the drain line, and check the refrigerant levels.
Annual Service Contract
Letscool Aircon and Services in Singapore offers both one-time and contract maintenance packages to keep your aircon performing efficiently year-round.
b. Keep the Air Filters Clean
Dirty filters restrict airflow, which can lead to frozen coils. Clean your filters every 2–4 weeks to ensure smooth airflow and optimal cooling.
c. Ensure Proper Installation
Always choose experienced professionals for installation. A correctly installed aircon ensures proper drainage and prevents future leakage problems.
d. Check for Signs of Damage
If you notice water pooling near your aircon or unusual noises, turn off the unit and contact a technician immediately. Early intervention can prevent more serious damage.
