Is Your AC Leaking Water? 4 Reasons For The Leak

What would we do without our air conditioners? Given the tropical climate of Singapore, you would be hard-pressed to find a household without a functioning aircon. However, as with any electrical appliance, constant usage and a lack of maintenance can result in your cooling appliance malfunctioning.

One of the most common problems you will encounter is water leakage. When your aircon starts leaking water, you could face numerous issues, including mouldy walls and poor aircon performance! So why is this happening, and what can you do to prevent this? Read on to find out.

Why is my aircon leaking water?

There could be several reasons why your aircon is leaking water. Here are the possible causes.

Reason #1: Poor installation

Poor aircon installation is the leading cause of water leakage. If you notice your aircon leaking water, it usually means the pipe is installed at a greater height or the fan coil unit (FCU) is not installed correctly. For the former, incorrect installation of the drain pipe can cause water to accumulate, clogging the piping and resulting in water leakage. As for the latter, if the FCU is not set up correctly, water cannot flow smoothly. As a result, water begins leaking from the front panel of the aircon.

Reason #2: Dirt and debris

When your aircon is not maintained regularly, dirt and debris will accumulate over time, blocking or clogging essential components. One of these key parts is the aircon drainage pipe. When the pipping is clogged, water cannot flow outwards. Instead, it accumulates and overflows to the main unit.

One detail many homeowners overlook is that their air conditioning condensate drains are tied to their bathroom drains. So if the inside of your bathroom floor tray is choked full of hair or dirt, it can also cause water leakage in your AC unit. So remember to clear any dirt or debris in your bathroom drains regularly. Additionally, we recommend opting for a drainage pipe at least 16mm thick. Some homeowners utilise a standard 13mm drainage pipe, which is more susceptible to clogging.

Two other crucial components to take note of are the air filter and FCU. When either part is clogged, airflow is blocked, and the cool air cannot fully discharge. This causes the evaporator coils and pipeline to freeze. Subsequently, ice starts to form over the coil, and when it melts, excess water is accumulated in the drainage pan. When the pan reaches maximum capacity, it overflows and causes water leakage in the main AC unit.

Reason #3: Poor or no insulation

Insulation is another crucial factor in preventing your aircon from leaking water. Adequate insulation stops the cables from freezing or heating up (depending on the room temperature), thus preventing moisture build-up. However, if there is insufficient insulation or lack thereof, condensation may occur on the aircon trunking.

Reason #4: Damaged drain pan

If your aircon installation is outdated, the drain pan responsible for collecting the condensate may become rusted or damaged. When this happens, water will not be collected correctly. Instead, it will leak through the main unit.

What should I do when my aircon starts leaking water?

Do not panic if you notice your aircon or aircon pipe is leaking. Contact a qualified technician immediately once you spot the issue. An experienced technician will conduct a thorough inspection of the aircon system and pipeline to identify the cause of the water leakage. Subsequently, they can propose the most suitable solution to rectify the issue.

If the issue is due to poor installation of the pipeline, the technician will readjust/re-gradient the pipeline to allow the water to flow downwards towards the drainage outlet. Conversely, if the issue lies with a poorly installed FCU, the technician can help re-install the component using Spirit Level Instrument Measuring Tools.

However, if the problem is caused by a clogged component(s), the technician will recommend a chemical wash to clear any dirt or debris blocking the affected part(s), thus resolving the water leaking issues.
