Why Is My Air Conditioner Leaking Water?

A well-functioning air conditioning (AC) system is crucial for the comfort of homes and workplaces in New South Wales (NSW) and the Blue Mountains region. However, at times, these indispensable systems can run into issues, one of the most common being water leaks.

At Altitude Air Solutions, we regularly handle service calls regarding leaking air cons. In this blog post, we’ll shed light on why your air con might be leaking water and what you can do about it.


5 Reasons Why Your Air Conditioner is Leaking Water

1. Clogged Drain Line

One of the most frequent causes of water leaks in air con units is a clogged drain line. The primary function of your AC is to remove humidity from the air, condensing it into water that drips down into a drain pan and eventually flows away through the drain line. A trusted air conditioning specialist can help you solve this issue.

Over time, however, this line can become blocked with dust, dirt, or mould, causing the water to back up and leak from the unit. Regular maintenance and professional cleaning can help prevent this issue.

2. Dirty Air Filters

Believe it or not, dirty air filters can lead to your air con leaking water. When air filters are clogged with dust and debris, it impedes airflow in the system. This blockage can cause the evaporator coil to freeze over. It can even contribute to unpleasant smells from your air conditioning and have an impact on your health, which air conditioning mainly drives positive impacts. When the unit is switched off or the temperature rises, this ice melts, causing an overflow in the drain pan and subsequent leaks. Regularly cleaning or replacing your air filters can prevent this problem.

3. Low Refrigerant Levels

Refrigerant plays a crucial role in your air con’s cooling process. When the refrigerant level is low, it lowers the system’s pressure, causing the evaporator coil to freeze, much like the scenario with dirty air filters. Again, when the ice melts, it may result in water leaks. Refrigerant levels can be checked and topped up by a qualified technician as part of a regular service.

4. Faulty Condensate Pump

In some air con systems, especially those located in basements, a condensate pump is used to pump the water outside. If this pump fails or breaks down, water cannot be effectively removed and may leak from the system. Regularly checking the condensate pump’s functionality can help prevent leaks and that’s where Altitude Air Solutions can help with regular servicing to prolong your system.

5. Improper Installation

If your air con unit is new and experiencing water leaks, it could be due to improper installation. An incorrectly sized or fitted drain pan, improper sealing, or an unlevelled indoor unit can all cause water to leak. Always ensure your air con system is installed by a licensed and experienced professional for optimal operation.

What to Do About Your Leaking Air Conditioner

If your air con unit is leaking water, the first step is to turn off the system to prevent any potential water damage. It’s recommended to contact a professional technician to diagnose and fix the issue. While some people may attempt DIY solutions, air conditioning systems are complex, and trying to repair them without the proper training can lead to further complications.
