Aircon water leaking

Air conditioning units are designed to cool and dehumidify the air in a room or building Aircon water leaking. As the air conditioner runs, it produces condensation, which is drained away through a drain line. However, if you notice that your air conditioner is dripping water, it could be a sign of a problem. There are several reasons why your air conditioner may be leaking water, including:

Clogged condensate drain line

Over time, dirt, dust, and other debris can accumulate in the drain line and cause it to clog. This blockage can cause water to back up and overflow from the drain pan, resulting in a water leak.

Dirty air filter: 

If the air filter in your air conditioner is dirty or clogged, it can restrict the flow of air and cause the evaporator coil to freeze. When the ice melts, it can result in water overflowing from the drain pan.

Damaged condensate pan

The condensate pan in your air conditioner collects the water that drips from the evaporator coil. If the pan is damaged or rusted, it can cause water to leak from the unit.

Improper aircon installation: If your air conditioner was not installed correctly, it can cause water to leak from the unit.

Now that we understand the potential causes of a leaking air conditioner, let’s discuss how to stop the leakage:


  1. Turn off the air conditioner: The first step is to turn off the air conditioner and unplug it to prevent any electrical hazards.
  2. Locate the drain line: Locate the drain line and check if it is clogged. If you can’t find the drain line, refer to the air conditioner manual.
  3. Unclog the drain line: Use a wet/dry vacuum to suction out any debris from the drain line. If this doesn’t work, you can use a long, thin brush or a wire hanger to gently remove the blockage.
  4. Clean the drain pan: Once the drain line is unclogged, clean the drain pan with a mixture of warm water and soap to remove any dirt or mold.
  5. Replace the air filter: If the air filter is dirty or clogged, replace it with a new one. This will improve airflow and prevent the evaporator coil from freezing.
  6. Check the condensate pan: Inspect the condensate pan for any damage or rust. If it is damaged, it may need to be changed.
  7. Check refrigerant levels: If the refrigerant levels are low, it may be necessary to call a professional technician to recharge the system.
  8. Call a professional: If the problem persists, or if you are unsure about how to fix the issue, it is best to call a professional air conditioning technician to inspect  and repair your unit.

Regular aircon service can also prevent water leakage from occurring. Professional technicians can perform routine maintenance, such as cleaning the air filter and inspecting the condensate drain line, to ensure the system is functioning correctly.
