Have you ever entered into your room and when you look up, you see the dripping of water in your aircond? It is amongst the most widespread issues of house owners in the state of Kuala Lumpur and Selangor, particularly, in rainy months.
The majority panics as it appears that something has gone wrong. However, the leaking aircond is a trifle problem in most instances, which can be easily fixed as soon as you know the cause. We will proceed with the 7 key reasons as to why your aircond is spouting water and what you can do to stop it.
1. Clogged or Blocked Drain Pipe
This is the number one reason for leaking water.
Your aircond purifies the air by taking out the humidity and expelling it through a pointless drain pipe. Over time, dust, algae, or dirt can block that pipe — and once it’s clogged, the water can’t flow out. It backs up into the indoor unit and drips from the front panel.
How to fix it:
If the aircon water leak is minor, you can try to using a small wet vacuum to clear the pipe. But for a full clean-up, it’s best to call a professional aircond repair technician. We use pressure tools to flush the drain and ensure no blockage remains.
2. Dirty Evaporator Coil
You have a cooling coil (the evaporator coil) in your aircond which absorbs the heat in your room. Air cannot move through the coil easily when it is covered by dust or dirt. The coil becomes very cold, ice circles it round; and as the ice melts, you see the dripping water. This often happens if your aircond hasn’t been cleaned for months.
How to fix it:
Schedule a proper cleaning. A chemical wash service removes all dust and mold that regular cleaning can’t reach. Keep clean aircon coils also help your unit cool faster and use less electricity.
3. Low Gas (Refrigerant) Level
When your aircond has low refrigerant, pressure caused by the refrigerant reduction within the system is reduced hence coil will be frozen. Leaks of water occur out of the indoor unit when the ice melts.
How to fix it:
You’ll need a qualified technician to check the gas level using proper gauges. At AirCond Care, we always check PSI before refilling. That way, you only pay for what’s needed — not too much or too little.
4. Rusted or Cracked Drain Pan
The drain pan under the coil of older aircond units is sometimes rusted or cracked. This causes water to escape before it could go to the drain pipe.
How to fix it:
In case the pan is rusty a patch could be a temporary solution, however replacement is generally wiser. An inspection may be prudent in case your unit is over the age of eight years and you may need to replace it with a modern, more efficient unit.
5. Installation Mistakes
Even the best aircond will leak if installed incorrectly.
The inside unit is sometimes not level, or the drain pipe is not angled in the proper way. Once it does, the water remains stagnant and spills out in front.
How to fix it:
Ask a repair technician to check the mounting position and pipe slope. A small adjustment can make a big difference — and prevent future leaks.
6. Frozen Coil from Poor Airflow
When your air filter is dirty or blocked, then air is not able to pass freely over the cooling coil. These results in developing ice and when the ice melts it drips.
This normally occurs when individuals fail to clean their filters which is quite easy yet it helps in eliminating so much trouble.
How to fix it:
Take out the front filter every month and rinse it with water. Let it dry completely before reinstalling. Clean filters mean smoother airflow, faster cooling, and no frozen coils.
7. Malaysia’s Humid Weather
Let’s face it — our climate doesn’t make things easy.
In Kuala Lumpur and Selangor, humidity can reach over 80%, and that creates a lot of condensation. Even if your aircond is working fine, excess moisture on the pipes or unit can drip onto the wall.
How to fix it:
Check that your insulation foam (on the copper pipes) isn’t torn. Also, make sure your windows and doors are closed when the aircond is running — that helps control humidity inside the room.
When to Call a Professional
