Why is your Aircon dripping or leaking Water, and how can you fix it?

Air conditioning is an indispensable household appliance in a tropical country like Singapore. It would help if you kept it running all the time to keep the House well ventilated and comfortable for daily activities. However, over time your air conditioner will likely develop problems, for example, due to lack of maintenance, constant use, and changing weather, all of which will lead to malfunctioning the cooling unit. Of all these problems concerning aircon, the most common is the leakage and dripping of Water.

If an Aircon leaks repair, it will cause additional stress because the device is not working correctly and will not provide you and your family with the proper cooling they need to withstand the heat. 

This problem, a curse for the existence of many Aircon owners, can be attributed to several factors. This article explains why Aircon leaks and drip Water and the steps you can take to fix the problem.

Common causes of leaking and dripping Aircon

Several causes cause the leakage and dripping of an Aircon.

Here are some possible culprits:

1. Air leak

Air leakage is one of the most common reasons that can cause the air conditioner to leak and Water to drip. For optimal operation, the Air that reaches the air conditioner must pass through the ventilation opening. Wrong reasons can lead to air leakage. The Air does not pass through the opening as it should. Air is likely to leak if this is not done, Airleading to suboptimal functionality.

To determine if there is an air leak, you need to perform simple troubleshooting by examining the device to determine if Air is leaking through the grilles around the vent. If there is an air leak, you need to take measures to eliminate the problem and prevent further leaks in the future.

2. Blocked air filter

It is another common reason for leaking Water in an air conditioner. If the air filter is clogged, it will inhibit the flow of Air through the system. It leads to freezing of the Air, and when you turn off the air conditioner or when the desired air temperature is reached, the ice formed on the filter begins to Melt. The Water finds its way out, and the air conditioner leaks.

3. Dirty air filter

If the air filter is clogged or dirty, the flow of Air to the evaporator is obstructed, which leads to a drop in temperature. If the coil gets too cold, it will freeze. When the air conditioner is turned off, the indoor unit stops sucking Air into the interior, leading to heating and melting accumulated ice. If this melting ice fills the capacity of the drip tray, it will lead to water leakage.

4. Pump failure

The condensate pump is a device that is located under the cooling coil. The function of the pump is to drain Water thoroughly, preventing leakage. If the pump is faulty or does not work correctly due to accumulation of dust and dirt, Water drips — a clear indication that the pump is not working correctly.

5. The condenser coil of the air conditioner is leaking

The condenser of your air conditioner is located outside your home. The unit consists of the condenser coil, a compressor, and the blower motor. Since the device is in the open Air, debris and dirt are more likely to accumulate, leading to clogging. It is one of the most common problems faced by many Singapore homeowners and air conditioner owners.

6. Blockage of the drain pipe

Clogging the drain pipe will cause your air conditioner to stop working. This problem occurs because deposits, mold, and certain types of mold accumulate excessively. If these substances accumulate in the drain, this leads to a slowdown in water flow from the air conditioner. It can lead to excessive water supply and spillage.

Statistical estimates show that due to the tropical nature of the climate in Singapore, the inflow of Water into air conditioners is slower than average. So if the drain pipe is clogged, this leads to little to no water flow. It can cause your air conditioner to leak and Water to drip.

7. Incorrect installation

If the air conditioner is not installed correctly, it can significantly cause water leakage. When installing the air conditioner, ensure the front is more excellent than the rear. It will ensure that the Water drains well, so it does not leak.

In many cases, the leakage is caused by improper installation. They should install your air conditioner with a suitable slope to prevent leakage. The incorrect inclination of the device can lead to improper drainage of Water.

8. Poor maintenance

Your air conditioner needs proper and timely maintenance like any other household appliance. Be sure to clean the device as often as possible. If necessary, seek professional help. You can also check that the evaporator coil is working correctly and ensure it is not rusting at an early stage. If you do not do it regularly, you can more often plague the problems that leak Water from the air conditioner.

9. Rusting the drain pan

When iron is involved, rust formation occurs due to the action of Water and Air (oxygen). Since the drain pan is made of metal, it rusts easily. Persistent rust in the drain pan is likely to lead to the device's clogging, hindering water flow to the outside. It eventually leads to spills and leads to leaks in the air conditioner.

10. Frozen air conditioner roller

The evaporator coil is located inside the air conditioner. If you open the door of your air conditioner and notice that the coil has accumulated in it, the melting rate is slower, leading to Water passing through the drain pan.

A significant cause of a frozen air conditioner is a dirty air filter. The filter is designed to prevent the flow of Air over the coil. If the filter is clogged with dirt, the hot stream will not be able to pass, and the temperature will drop. As a result, ice accumulation occurs due to freezing.

11. Outside temperature too cool

If the outside temperature is too cool, your air conditioner will freeze. It happens mainly at night, when the temperature drops below 60 degrees Fahrenheit, adversely affecting the cooling coil.

12. Clogged condensation line

An Aircon sucks moist and warm Air from indoor rooms and blows it over frozen pipes. The coils are colder than the Air because it is filled with cold refrigerant. The moisture vapor in the Air condenses on the cold coil and turns into liquid Water. If the Water is not properly collected and drained, the air conditioner will drip.

A drain pipe causes the flow of water to accumulate in the air conditioner. The drain pipe allows the water to pass through without dripping out. If you notice that the drip tray is full or overflowing, this is a cause for concern. In addition, if the area is already rusted, it is serious, and you need to seek professional help urgently.

How to repair a dripping or leaking air conditioner?

It is essential to take measures such as cleaning and dusting the condensate drain and internal and external Flushing. Here are some specific tips and steps to follow:

‍

1. Cleaning and dusting of the condensate drain

The condenser sucks the hot Air out of your room, cools the Air, and lets the cool Air into the room. The hot Air condenses and turns into Water.

The Water is drained through the condensate drain pan and the condensate pipe of the device. It is important to note that lack of regular maintenance and accumulation of dirt and dust will lead to clogging of drain pipes.

You can perform the following steps:

Please turn off the Aircon and unplug it. It is for safety.

Unscrew the access plate to find the condensate drain pan. The condensate drain is located at a saturation point under the evaporator coils.

Check if Water comes out of the pan. If so, there is a chance that the drain is clogged. Soak the Water and wash the pan with a dry cloth.

Use a wet vacuum cleaner. It will help get rid of the blockage in the drain pipe. Using the cleaning machine from the endpoint of the drain opening outside the House is good. It allows you to remove all dirt, dirt, and mold in the drain. You can also exclude the possibility of returning the dirt to the drain pipe.

If necessary, you can use the high-pressure suction pump. Although cleaning up the debris and dirt is a bit time-consuming, it's worth investing the time it takes to clean up.

Continue to blow the suction continuously for at least one minute.

Each time, check the canister to what extent dirt has been removed.
