Aircon Leaking Water in Singapore
Indoor dripping usually starts from drainage blockage, heavy dirt buildup or airflow problems that create excess condensation and overflow. We diagnose the real leak path before repair.
What This Page Helps You Narrow Down
- Best for water dripping from the indoor unit, nearby wall, casing edge or ceiling void close to the FCU path.
- We distinguish between drainage issues, condensation overflow and faults caused by poor cooling performance.
- Share photos of the leak point and whether the unit is still cooling normally.
Most Common Root Causes
We use symptom-first diagnosis so the final recommendation matches the actual issue, not just the most obvious surface sign.
Blocked drainage pipe
The most common cause. Sludge and dirt buildup can slow or fully stop condensate flow.
Dirty fan coil causing icing and overflow
Heavy dirt can affect airflow, create icing, then lead to water overflow once the ice melts.
Drain tray or slope problem
Misalignment, poor fall direction or tray condition can redirect water out of the intended route.
Repeated not-cold issue causing condensation imbalance
If a unit is both not cold and leaking, the leak may be a secondary symptom of deeper cooling failure.
What We Check On Site
- Exact leak point: front panel, corner, pipe trunking, wall or ceiling area.
- Whether the leak started after servicing, renovation or heavy recent use.
- Drainage flow and blockage severity.
- Fan-coil dirt condition and icing signs.
- Any linked not-cold, noisy or smell symptoms that indicate wider fault scope.
When To Prioritize Urgent Support
- Water is reaching electrical points, flooring joints or furniture.
- The same unit leaks again shortly after prior cleaning.
- Leak happens together with weak cooling and icing.
- There is ceiling staining or potential downstream neighbour impact in condo/HDB settings.

Frequently Asked Questions
Can you fix leaking water without chemical wash?
Sometimes yes. If the main issue is a drain choke, flushing and cleaning may be enough. We inspect first before recommending deeper work.
Why does my aircon only leak after running for a while?
That usually points to drainage backup, icing or airflow-related condensation overload that builds up during runtime.
Should I keep using the leaking unit?
If water is reaching electrical points, flooring or furniture, it is safer to switch the unit off and send us a photo or video for quicker triage.
Do you also check not-cold issues on the same visit?
Yes. Leak and cooling-loss symptoms often overlap, so we check the linked causes together when needed.
Can I get a faster quote through WhatsApp?
Yes. Send the unit model, address and a short leak video so we can advise the likely visit type before arrival.
