Why is My Aircon Leaking Water? How to Fix It
Air conditioners may have once been a luxury, but in today’s scorching Singapore heat, they have quickly turned into a necessity. With that being said, owning an aircon (or several) means there is a bit of upkeep involved to keep it running as it should.
Have you ever noticed your aircon unit dripping or spotted a puddle of water beneath it? That is a clear sign something is off. While it is normal for air conditioners to produce some moisture, too much of it can spell trouble, from water damage to mould growth and even higher energy bills.
However, we come with good news as most of these issues can be prevented with regular maintenance and a few simple precautions! In this article, we will explore what causes aircon condensation, the problems it can lead to, and tips you can take to prevent it.
What is Aircon Condensation?
Before we talk about what causes condensation, let’s quickly cover what is condensation. Air conditioners cool down warm air by pulling out moisture, which then exits through a drainage system. When this process is interrupted, the unit starts leaking inside the house which can lead to several problems.
Most air conditioning units are designed to handle a normal amount of condensation, but too much of it can lead to trouble. If excess condensation is not dealt with, it can lead to corrosion and leaks, damaging the unit and leading to costly repairs.
What Causes Aircon Leaking Water?
Constantly checking your air conditioner for signs of excess moisture can help catch these issues early, saving you from bigger problems down the line. Here are some of the most common reasons for aircon condensation:
Clogged Drain Pipes
Drain pipes are the “exit lane” for the moisture your aircon collects. If they get clogged with dust, dirt, or even mould, the water has nowhere to go, so it starts pooling around the unit. A blocked drain pipe is one of the top reasons for condensation issues.
Dirty Air Filters
If your air filter hasn’t been cleaned or changed in a while, it can restrict airflow. When air cannot move freely through the system, it creates pressure that can lead to extra moisture buildup.
In these cases, the aircon has to work harder, which means pulling more moisture out, and without proper airflow, that moisture cannot escape efficiently.
Low Refrigerant Levels
Low refrigerant can cause the temperature in your aircon coils to drop too much, leading to excessive condensation on the pipes. You know how sometimes you leave a cold drink out on a hot day and water droplets form on the outside? The same thing happens to your aircon pipes when refrigerant levels are irregular.
Improper Installation
Sometimes, the issue traces back to the installation. If your aircon unit was not set up with the right tilt or angle, it can mess with the drainage system. Water does not flow out of the unit correctly and may start to accumulate.
Humidity Levels
If your home’s humidity level is consistently high, the aircon has to work harder to keep surfaces dry. If it is not able to keep up with that, condensation happens.
Common Aircon Problems When There Is Condensation
As mentioned earlier, air conditioners are designed to deal with condensations but to an extent. Excess condensation in your aircon can lead to a range of issues. Here is what to watch out for:
Corrosion of Aircon Coils
When condensation builds up on your aircon’s coils, it can cause corrosion. Over time, this corrosion forces the unit to work harder to cool your space, increasing energy use and ultimately hiking up utility bills. If left unchecked, it can even reduce the aircon’s lifespan.
Growth of Mould and Mildew
High moisture levels from condensation create the perfect environment for mould and mildew to thrive. Mould can trigger respiratory issues like allergies, asthma, and bronchitis, and, in extreme cases, pose more serious health risks.
Water Damage
If condensation is not draining correctly, it can lead to water damage in your home. You will start to see stained ceilings and walls, warped floors, or even damaged furniture—issues that can be costly to repair.
Unpleasant Odours
A musty or damp smell can develop when condensation builds up in your aircon, making your home uncomfortable.
How to Fix When My Aircon is Leaking Water?
Now that you are aware of the causes of condensation, here are some steps you can take when you notice it happening:
Check and Clear the Drain Pipe
If you suspect a clog, take a look at the drain pipe. You can do this by turning off the unit and gently unclogging it with a vacuum or blowing air through it to remove any blockages. Just be careful and make sure the pipe isn’t damaged.
Clean or Replace Air Filters
Dirty air filters can lead to all kinds of issues, so this definitely needs to be inspected. Turn off the aircon, remove the filters, and give them a good rinse or replace them if they are worn out. Clean filters also help air flow smoothly and reduce moisture buildup.
Control Indoor Humidity
If your area is known for high humidity, using a dehumidifier can be a great way to help your aircon out. Lowering the humidity in your home will reduce the amount of moisture the aircon has to pull from the air, meaning less condensation overall.
Check Refrigerant Levels
Low refrigerant can only be dealt with by a professional, as handling refrigerant requires specific tools and skills. If you have taken all the steps above and still have leakage issues, you may need to call a professional to check your refrigerant levels.
Adjust the Unit’s Position
A poorly installed aircon might need some adjusting. If the unit is tilted or off-balance, the water might not drain out properly. It is best to leave it to a professional who can help realign the unit for optimal drainage.
Preventing Future Aircon Condensation Issues
Schedule Regular Maintenance
A professional check-up at least once a year can catch any issues early. Professionals will clean out the system, check refrigerant levels, and make sure your aircon is set up correctly.
Keep Air Filters Clean
Constantly cleaning or replacing your air filters can help prevent a lot of issues before they even start. Aim to clean them every one to three months, depending on how often you use the unit.
Watch for Signs of Clogging
If you notice water pooling around the aircon, it is a sign to check the drainage pipes sooner rather than later. If you are dealing with excessive aircon condensation, reaching out to a professional can help.

Frequently Asked Questions
Should I turn off my aircon if it is leaking?
If the leak is near a power outlet or you see water pooling, it is safer to turn it off and get it looked at. If not, you can leave it running for now.
What is the fastest way to stop the leak?
Start by cleaning the filters or checking the drainage pipe. If it is still dripping, best to call in a technician.
Is the water clean or should I be worried?
It is not dirty, but it is not exactly clean either. It comes from the moisture in the air, so you don’t want it soaking into anything.
