Seeing water dripping from the outdoor condenser unit often worries homeowners. The good news is that in many cases, this is normal behaviour, but in some situations, it can also signal an underlying issue.
Understanding the difference helps you know when to monitor the situation and when to arrange a check.

When Condenser Water Dripping Is Normal
The condenser unit releases heat from your home into the outdoor air. During this process, condensation can form and drip off naturally.
This is more common when:
The aircon is running for long hours
Outdoor humidity is high (very common in Singapore)
The system is cooling efficiently
The weather is hot and humid
In these cases, clear, clean water dripping occasionally is normal and not a cause for concern.
When Condenser Dripping Indicates a Problem
Water dripping excessively or continuously may point to an issue.
Common causes include:
1. Dirty or Blocked Condenser Coil
Dust, debris, or grease buildup restrict airflow around the outdoor coil. This reduces heat release and leads to excess condensation.
Signs:
Heavy dripping
Reduced cooling performance
Higher electricity consumption
2. Frozen System Thawing
If the indoor evaporator coil freezes and later melts, excess water may drain towards the outdoor unit.
Possible causes:
Low refrigerant (gas)
Dirty filters or coil
Weak airflow
3. Drainage or Installation Issues
Improper installation can cause water to flow in unintended directions.
Examples include:
Incorrect piping slope
Drain line positioning issues
Condenser base not level
4. Overworked Aircon System
When the aircon works harder than usual due to dirty components or poor airflow, more moisture forms throughout the system.
This can lead to heavier dripping at the condenser.
What You Should Do
If condenser water dripping is:
Light and occasional → usually normal
Heavy, constant, or sudden → should be checked
You should arrange servicing if:
Cooling performance drops
Water pooling becomes excessive
Dripping appears together with noise or smell
