How To Repair Mitsubishi Aircon Leaking Problem?

Is your Mitsubishi Aircon leaking? If it is, you do not need to worry. It is one of the most common problems with aircons. Thankfully, there are some easy steps you can take to repair your Mitsubishi Aircon.

In Singapore, it is almost impossible to live without aircon. The hot and humid climate makes air conditioning necessary and Mitsubishi is one of the bestselling brands in Singapore. However, even the best brands need to be serviced regularly to ensure that they keep working in good condition at all times. If the Aircon unit is not serviced on a regular basis, problems will start developing and small problems may turn into big problems if left unattended for a long time.

Reason for Aircon Water Leakage

First of all, you need to understand the reason for the Aircon leaking. Usually, it is caused by water collecting in the drain tray. There is a condensation tray inside the Aircon which collects the water from the inside coil. This water is then drained out of the Aircon unit with the condensation drain tube.

However, there are times when this process does not work as it should and water starts leaking. This leakage can cause growth of mold and mildew. It can also ruin the interiors of your house or office. Therefore, it is important to fix the leaking problem at the earliest.

Steps for Aircon Repair

To stop the water leaking, first of all you need to remove the aircon from the window. One should take care while removing the unit as it’s a bit heavy and may not be removable by a single person. Once the air conditioning unit has been removed, it needs to be placed on a level and firm surface. Do not place it on grass or dirt as it may result in damage to the outside covering of the unit.

Next up is to remove the outer covering of the unit. This can be done with the help of a screwdriver. Most of the air conditioning units use anywhere from 4 to 6 screws for holding the unit in the frame. However, there are some models that use more than six screws. Therefore you need to be careful while removing the unit as unnecessary force to remove the frame without unscrewing the remaining screws may damage the hole permanently.

Once you have successfully removed the outer covering, you will see a plastic tray on the bottom of the unit. This tray collects the condensed water on the coil which is then taken outside through the drain tube. You may also notice dust and mould growth in the tray due to water. To clean the drain pipe, you can connect it to a garden hose and let water flow through it. Once water has flown for about 5 to 10 min, you also need to put some house bleach in to the drain pipe to clean it completely. It is recommended to let the bleach to stay in the drain pipe for at least 10 min for thorough cleaning.

Now, connect the garden hose with the drain pipe again to clear the house bleach. Also clean the inside of the Aircon with a garden hose. Spray the water at a moderate pressure inside the air conditioning unit. Also clean the drain tray with a garden hose as there may be some solid debris inside the tray that need to be cleaned. Clean the interior and exterior coils along with the interior filter for complete cleaning of the aircon unit.

Your aircon unit should be completely clean now. Now it is time to dry the aircon. You can place the aircon in sunlight to dry.

Once it is completely dried up, just reverse the process followed while opening the outer frame. Now fix it in the window and check whether water leakage has stopped or not. In case it has not stopped, there may be some other problem with the unit that can be checked and repaired by a trained technician.

The best way to ensure that water leakage never occurs is to get the aircon service done at regular intervals. If you are short of time, there are many air conditioning service companies that will service your aircon unit for a small fee. Always remember that small issues can develop into big problems if not taken care of at the beginning.
