Why is Daikin aircon leaking water?
Posted: Feb 02, 2026
Daikin aircon leaking water
Daikin air conditioners are known for their reliability and strong cooling performance, making them a popular choice in many Singapore homes and offices. However, like any aircon system, they can sometimes experience issues — one of the most common being aircon water leakaging.

Water dripping from your Daikin unit is not only inconvenient but can also signal underlying problems that may affect your aircon’s efficiency and lifespan. In Singapore’s humid climate, prompt attention is essential to avoid further damage. Let’s explore why your Daikin aircon might be leaking water and how professional servicing can solve the issue.
Clogged Drainage System – The Most Common CauseThe primary reason for water leakage in Daikin aircon units is a blocked drainage pipe. During normal operation, moisture in the air condenses and flows out through the drainage system. Over time, dirt, dust, and mold build up inside the pipe, preventing water from flowing out properly.
When this happens, water backs up and starts dripping from the indoor unit.
Signs of a clogged drain include:
Visible water dripping from the aircon
Musty smell from the unit
Reduced cooling performance
Regular aircon general servicing helps prevent this issue by cleaning drainage pipes and removing blockages before they cause leakage.
For heavy buildup, a professional aircon chemical wash or aircon steam wash can thoroughly clean the system and restore proper water flow.
Dirty Coils and Filters Causing Excess CondensationAnother major reason for water leakage is dirty evaporator coils and clogged air filters. When dust accumulates on these components, airflow becomes restricted. This can cause the coils to freeze and later melt, resulting in excess water dripping from the unit.
You may also notice:
Aircon not cold despite running for long periods
Higher electricity bills
Weak airflow
In severe cases, deep cleaning with an aircon chemical overhaul is required to remove stubborn dirt inside the unit and internal components.
Routine aircon servicing Singapore keeps coils clean, improves cooling efficiency, and prevents water leakage problems.
Low Refrigerant Levels or Internal Component IssuesLow refrigerant levels can also contribute to water leakage. When your Daikin aircon requires frequent aircon gas top up, it may indicate a refrigerant leak. Low gas levels cause pressure imbalances that lead to coil freezing and water dripping once the ice melts.
In some cases, damaged internal parts such as sensors, fans, or aircon spare parts may disrupt normal operation.
You may experience:
Aircon light blinking on the display
Appearance of an aircon error code
Unusual noises from the system
These signs usually require professional aircon repair Singapore services to diagnose and fix the root cause.
If the issue involves the compressor, specialized aircon compressor servicing may be necessary to restore system performance.
