Have you noticed water leaking from your indoor aircon unit? Chances are, your aircon drain line might be clogged and causing the problem.
But don’t worry — it’s a common issue in humid places like Singapore. The good news is, you can often clear a blocked drain line yourself with a few simple steps.
In this article, we’ll explain what an aircon drain line does, why the drain line gets blocked, and how to unclog your aircon drain line safely at home. If you’ve been dealing with leaks or water buildup, it’s likely time to check and clean that drain line before it leads to bigger issues.
What Is an Aircon Drain Line?
First of all, your aircon doesn’t just cool the air — it also removes moisture.
This moisture turns into water, which drains out through a small pipe called the condensate drain line.
However, over time, dirt, dust, and algae can build up inside this line.
As a result, it gets blocked, and water backs up, causing leaks.
Signs Your Aircon Drain Line Is Clogged
Now, how do you know if your aircon’s drain line is blocked?
Look out for these common signs:
✔️ Water leaking from the indoor unit
✔️ Aircon stops cooling properly
✔️ A musty smell from the aircon
✔️ Blinking indicator lights
If you notice these symptoms, it’s time to check and unclog your drain line.
How to Unclog Your Aircon Drain Line
So, how can you fix this problem?
Follow these simple steps:
Turn Off Your Aircon
Firstly, for safety, switch off your aircon and unplug it from the power source.
Locate the Drain Line
Next, find your aircon’s drain pipe.
Usually, it’s a white PVC or rubber tube attached to your indoor unit.
Check for Visible Dirt
Then, inspect the drain line’s opening for dirt, dust, or slime.
If you see any, wipe it clean with a cloth.
Use a Vacuum Cleaner
In addition, you can use a wet/dry vacuum cleaner to suck out the clog.
Place the vacuum hose over the end of the drain line, seal it tightly with your hand, and turn the vacuum on for 1–2 minutes.
Flush with Warm Water
Lastly, pour a mixture of warm water and a little vinegar through the drain line to clear any remaining dirt or algae.
This simple step helps keep it clean and odour-free.
