Aircon water leaking
Installing a new air conditioner should provide reliable cooling and comfort. However, some homeowners notice water dripping from the indoor unit shortly after installation. If you’re wondering, “Why is my aircon leaking after installation?”, you’re not alone. Water leakage is a common issue that can occur due to installation errors, drainage problems, or environmental factors.
At LetsCool Aircon, we provide professional aircon servicing Singapore, aircon repair Singapore, and aircon installation Singapore services to ensure your system operates efficiently from day one. Understanding the reasons behind a leaking air conditioner can help you prevent costly repairs and maintain optimal performance.
Is It Normal for a New Aircon to Leak Water?
A properly installed air conditioner should not leak water inside your home. During normal operation, the evaporator coil removes moisture from the air. This water flows into a drain pan and exits through the condensate drain pipe.
If water starts dripping from the indoor unit after installation, it usually indicates that something is preventing proper drainage or that the installation wasn’t completed correctly.
Common Reasons Why Your Aircon Is Leaking After Installation
1. Incorrect Installation Angle
One of the most common causes of water leakage is improper aircon installation.
The indoor unit should be mounted with a slight tilt toward the drainage outlet. If the unit is installed unevenly, water cannot flow into the drain pipe properly and may overflow into your room.
Professional technicians carefully check the mounting angle during installation to prevent this issue.
2. Blocked Drain Pipe
The condensate drain pipe carries water outside your home.
If the pipe becomes blocked by dust, dirt, insects, or construction debris shortly after installation, water backs up into the indoor unit and starts leaking.
Regular Aircon service price helps keep the drainage system clean and functioning properly.
3. Poor Drain Pipe Installation
Even if the drain pipe is clean, incorrect installation can cause problems.
Common mistakes include:
- Loose drain pipe connections
- Improper pipe slope
- Kinked drain hose
- Crushed drainage pipe
These issues prevent water from flowing smoothly, leading to indoor leaks.
4. Frozen Evaporator Coil
A frozen evaporator coil can create excessive water leakage after it melts.
Common causes include:
- Dirty air filters
- Poor airflow
- Low refrigerant levels
- Faulty blower fan
Once the ice melts, the drain pan may overflow, causing water to drip from the indoor unit.
5. Low Refrigerant Gas
Many homeowners don’t realize that low refrigerant can indirectly cause water leakage.
When refrigerant levels are low, the evaporator coil becomes extremely cold and freezes. After the air conditioner is switched off, the melting ice produces more water than the drain system can handle.
A professional inspection can determine whether your system requires an aircon error code or leak repair.
6. Dirty Air Filters
Air filters play a major role in maintaining airflow.
When filters become clogged with dust:
- Air circulation decreases
- Evaporator coils freeze
- Ice melts later
- Excess water leaks indoors
Cleaning filters every few weeks helps prevent this problem and improves cooling efficiency.
7. Damaged Drain Pan
Although uncommon in new systems, the drain pan may become damaged during transportation or installation.
Cracks or manufacturing defects allow water to escape before reaching the drain pipe.
A technician can inspect and replace the drain pan if necessary.

8. High Humidity Levels
Singapore’s tropical climate creates high humidity throughout the year.
During extremely humid weather, your air conditioner produces more condensation than usual. If the drainage system is not installed correctly, this extra moisture can overflow and cause leaks.
Routine aircon servicing Singapore ensures your drainage system can handle heavy condensation.
Signs Your Aircon Needs Immediate Attention
Watch for these warning signs after installation:
- Water dripping from the indoor unit
- Water stains on walls or ceilings
- Musty or damp smell
- Reduced cooling performance
- Gurgling or unusual sounds
- Ice forming on the evaporator coil
- Frequent system shutdowns
Ignoring these symptoms may result in more expensive repairs later.
Can Water Leakage Damage Your Home?

- Wooden floor damage
- Mold growth
- Electrical hazards
- Higher repair costs
Early diagnosis prevents extensive property damage.
