Why Is My Air Cooler Leaking Water? (And How To Fix It)

One of the most common and recurring problems air cooler owners face is the leaking of water from their units. While it is obvious where the water is coming from (i.e. the water that you’ve put in the unit), it is unsure what is causing the water tank or the honeycomb pad to not hold in the water.

Water leaking from the air cooler may be the result of a simple over-filling of water, or it may be because the reservoir is broken or was not attached properly. It could also be because the water-soaked honeycomb pad is broken and thus could not hold in the water.

In this article, we will discuss why your air cooler is leaking water, and how to fix it.

How does an air cooler work?

Air coolers work by harnessing the power of the evaporation process; it passes air through a water-soaked medium. The water, while it evaporates, cools the air (akin to the cooling effects of sweat as it evaporates). This cool air is then blown out by the air cooler’s fan.

The two parts that are most likely to cause this leaking problem is the water tank and the honeycomb pad.

Common causes of a leaking air cooler and how to fix them

These are the most common reasons of a leaking air cooler and what to do with them:

1. Overflow

One simple reason why your air cooler is leaking water is because you’ve overfilled it. For models that have an ice compartment, it may be because the ice has already melted and overflowed from the compartment.

The fix: Nothing really. Just observe the proper water level next time. Also, do not move or tilt your air cooler if it is already filled.

2. Broken water tank

If the water is coming from the bottom of your air cooler, then it may be because there is a hole in the water tank. While rust won’t be the issue here as water tanks are usually made from plastic, accidental puncturing during cleaning or installing may happen.

The fix: You can apply an elastomeric sealer on the hole if it is small enough. If your warranty still applies, you may get it fixed with the company’s technicians.

3. Water tank was not attached properly

The water may leak if the water tank was not installed back to its proper place. This is more common in models with a detachable water tank.

The fix: Turn off the unit and re-install the water reservoir – properly this time.

4. The honeycomb pad is broken

The honeycomb pad – the water-soaked pad that the air passes through, may get damaged accidentally during cleaning. This can result in it not being able to hold water and leaking it all over your floor.

The fix: Try to get it repaired by a technician. If it is not possible, you can buy a replacement honeycomb pad for your unit.

5. The honeycomb pad was not installed properly

If you installed the honeycomb pad incorrectly, it may cause it to leak water. Also, if you bought a replacement pad in the wrong size, it may not be able to soak the water effectively.

The fix: Turn off the unit and re-install the honeycomb pad. Also, if you are going to replace the pad, make sure that the size is compatible to your unit.

Conclusion

Leaking water from your air cooler may just be a nuisance at its worst, but it is easily preventable by just being observant. The fixes are also easy enough to do on your own. Don’t sweat about it too much!
