5 Reasons Why Your Aircon Leaking Water

An air conditioner is a must-have appliance in Singaporean households. We need to keep it running to maintain our homes cool and comfortable in a sunny climate. However, our air conditioner is prone to malfunctioning with time, especially if it is not serviced regularly. One of the most prevalent issues is – an air conditioner leaking water.

If your air conditioner is leaking water, you should be aware that the harm it may do to your home is significant. It might begin as a minor problem and progress to the damage of ceilings and walls, air pollution, and even an increase in your electricity costs.

So, why is the air conditioner leaking?

Here are the most common reasons why your air conditioner is dripping water and how to stop it.

1. Blocked and Dirty Aircon Filters

Dirty air conditioner filters are one of the most common reasons that may lead to the air conditioner leaking water. If your air conditioner’s filter is dirty and clogged, it will restrict airflow to the evaporator coil. Without warm air absorbed by the refrigerant in the coil, the chemical liquid does not heat up and turns into a gas, causing it to freeze. As a result, water leaks out of the air conditioning unit as the frozen coil melts. To avoid this problem, we recommend cleaning the air filter once every three months or less. 

Fortunately, Kaodim’s air conditioning professionals can gladly assist you with cleaning the filters on your air conditioner, ensuring that it operates efficiently.

2. Insufficient Gas

Another reason for the air conditioner leaking water is insufficient gas to cool the air. When the air conditioner does not have enough refrigerant to cool the air, the evaporator coil may not be able to condense the air, resulting in water leaks. If your air conditioner’s condenser is making bubbling or hissing noises, your refrigerant is likely leaking. If this is the case, you will need to have an aircon expert inspect your AC unit as soon as possible. In the long run, ignoring these sounds could damage the AC unit, such as a broken part that may be too late to fix.

3. Incorrect installation

A defective aircon installation is a typical cause of an air conditioner dripping water

The first thing you should do is examine the seals to ensure that they are properly placed. If the seals are not correctly installed, warm air from the outside will collide with cold air from the condenser, resulting in condensation and leakage. Furthermore, you should also check whether your air conditioning was installed on a flat surface. This is because it must be adjusted to a slight downward slope for the water to flow out freely.

If you discover any problems, you should contact reliable air conditioning experts that specialize in air conditioning installations to conduct an inspection.

4. Broken or damaged drain pan

Additionally, your air conditioner may be leaking water due to a damaged drain pan. Regardless of the type of air conditioning unit, the drain pan is located just underneath the evaporator coil. Your air conditioner’s drain pan collects the moisture that drips from the coils. If the drain pan overflows, your air conditioning unit may leak water, so it’s important to clean it. We recommend contacting a professional to repair the drain pan because it could be challenging to do so yourself. 

5. Air Leak

Lastly, one of the most common causes of water leaking from an air conditioner is an air leak near the vent. Air leaks can occur as a result of poor seals. Simply put, you should carefully inspect the unit to discover whether air is coming from anywhere other than the grates themselves. If this is the case, contact an air conditioning service to repair or replace them.

We hope that the information we have provided will help you better understand some of the most common causes of air conditioning leaks.  Like any other household appliance, your air conditioner requires regular air conditioning maintenance to work at its best. Having your air conditioner checked regularly is a great way to avoid leaks and extend the lifespan of your AC unit. You can always count on dependable aircon specialists at Kaodim who are ready to help you with aircon maintenance anytime you need it!
