Common signs of an AC water leak
You may need service if:
- water drips from the indoor unit
- water runs down the wall
- the AC leaks after running for a while
- there is water on the floor under the unit
- the AC smells damp
- the unit makes bubbling or dripping sounds
- the leak happens during rainy or humid weather
- the AC has weak cooling and water leak together
Do not ignore repeated water leaks. The issue may get worse and cause damage to your room.
Why aircon units leak water
There are several possible causes.
Clogged drain pipe
Dust, slime, mold, and dirt can block the drain line. When water cannot drain properly, it may drip from the indoor unit.
Dirty cooling coil
A dirty coil can disrupt normal water flow and increase dripping risk. Regular aircon cleaning helps reduce this risk.
Blocked drain tray
The tray inside the unit can collect buildup over time.
Poor installation angle
If the unit or drain line is not installed at the right angle, water may not flow out correctly.
Frozen coil
If the coil freezes and then melts, water can overflow. This may be related to airflow or gas issues.
Low gas or cooling problem
Some cooling problems can create freezing or abnormal condensation. See aircon not cold and gas refill for more.
What our technician checks
For aircon leaking water issues, the technician may check:
- indoor unit condition
- filter and coil buildup
- drain tray
- drain pipe blockage
- water flow
- installation angle
- cooling performance
- signs of freezing
- signs of low gas or related issues
The solution depends on the actual cause. Some leaks can be fixed by cleaning and drain clearing. Others may need repair or adjustment.
Why this is common in Bangkok
Bangkok's humidity, dust, daily AC use, and condo lifestyle make water leaks common. If the AC is used every night and has not been cleaned recently, dirt and moisture can build up inside the system.
Condos near busy roads, construction areas, or high-dust zones may need more frequent maintenance.
Emergency steps before technician arrives
If water is leaking heavily:
- turn off the AC
- move furniture or electronics away
- place a bucket or towel under the leak
- take photos or video
- do not open the unit yourself if unsure
- message Bangkok AC on LINE
This helps reduce damage while waiting for service.
