There are quite a few reasons why your aircon may be leaking so here’s how to troubleshoot and fix it.

Frozen Evaporator Coils

Frozen coils are usually the main culprit for your aircon leaking water. Open the front panel of your aircon and see if there is a layer of ice on your evaporator coils. When this problem continues without be rectified it can lead to further damage to the aircon compressor. Frozen coils are attributed to occur when there is a refrigerant leak or there is a reduction of airflow on the coils which might subsequently lead to the clogged air filter.

 

There can be many attributions to why your evaporator coils might have been frozen, and the best way to determine the cause would be to call an aircon servicing company to check it out. If you would still like to know how to determine it yourself, you can read on Ways to Check Why Your Aircon Is Leaking Water.

Damaged drain pan

The drain pan helps to collect any condensate but when this overflows, could cause your aircon to leak water as well. Corrosion might also cause the aircon water tray to have openings that will cause the condensate to leak from where it’s being held. The pan is made of iron which makes it susceptible to rust because of a combination of water and oxygen. 

How to fix: The drainage tray is not easily accessible due the fact it is closely located near the aircon drain pipe, which is not something you can access easily either. As such call an aircon servicing company to help you check it out.

Clogged drain line

Clogged drain lines are some of the common reasons why the air conditioner starts leaking. This is the pipe that receives the condensate from the drain pan and sends the excess outside. The drain pipe can be clogged with dirt due to the lack of proper aircon cleaning, and thus cause a backflow of the water collected in the drainage tray. This is commonly diagnosed if the aircon leak seems to start at the back of your aircon. 

How to fix: As this part is inaccessible to you and requires some aircon repair, get a professional aircon service company to help you unclog it.

Most people neglect their air filters until something goes wrong with their aircon, but as a matter of fact, they greatly contribute to dripping and water leakages in the air conditioner. A dirty air filter blocks the airflow in the evaporator coil which causes it to freeze. Therefore, when it melts, the water leaks out of the aircon. When your aircon starts showing signs that it needs to undergo an aircon servicing, do it before it leads to further problems with your aircon.

How to fix: The air filter should be cleaned regularly every 3 months or less. This promotes clean air, stronger cooling and the easy This prevents water from leaking out of the air conditioner.

Improper installation

If you are having a new air conditioner unit and you notice there are some water leakages, then it most likely due to a faulty aircon installation. you should not think of filters and drain lines as the reason behind it. The incorrect aircon installation is what has caused water leakage. Therefore, you should start by checking if the air-conditioner was installed on a flat surface. This is because it needs to be installed a slight downward angle for the water to drip off easily. Additionally, you should check if the seals are properly fitted because if not then the warm air from the outside will meet with the cold air from the condenser leading to condensation which contributes to leakages.

How to fix: When there is improper installation don’t try to fix it on your own because you might end up damaging other components. The best thing to do is to contact a reputable aircon service company that does aircon installations to come have a look.

Refrigerant coolants help to cool the warm air and billow it out for your comfort. If there is not enough gas, then the aircon will not blow cold air, and the air might fail to condense on the evaporator coil, leading to your aircon leaking water. You might also hear some bubbling noise or hissing sound which indicates that there is a likelihood that the aircon coolant is leaking and you need an aircon repair immediately. 

How to fix: You will simply need an aircon gas top up, but if you suspect that the aircon leaking water may be leaking refrigerant instead, you need to contact us quickly, as it is harmful to you and the environment.

The condenser unit is your outdoor aircon unit and its major parts comprise of the condenser coil, the compressor, and the fan motor. As it is located outside of the house, it is likely to accumulate a lot of grime and dirt which would lead to a blockage. As such, all the above factors of aircon leaking will also show up here. 

How to fix: You will need to disconnect the air conditioner from the power source, then dismantle its various outer parts to access the condenser coils. Normally if it is only a little bit of grease and dirt, you can use a brush and a cloth with effective cleaning agent to wash it down. 

 

However, if the condition is serious enough, it might require an aircon chemical overhaul service. To seek advice about your aircon’s condition, please feel free to chat with our friendly aircon customer service who can tell you more on what you might need done!
