Why Is My Air Conditioner Leaking Water?
Air conditioners remove humidity from the air, which forms condensation. This moisture is usually drained away, but if something goes wrong, you may notice water leaking from your aircon unit.

Common Causes of Air Con Leaks:
1. Clogged or Blocked Drain Line
The drain line carries condensation away from your AC unit. If itβs blocked by dust, dirt, or mould, water has nowhere to go, leading to leaks.
π‘ Solution:
β Use a wet/dry vacuum to clear blockages.
β Flush the drain line with vinegar or warm water.
2. Dirty Air Filters
A clogged air filter restricts airflow, causing the evaporator coil to freeze. When it melts, excess water overflows from the drain pan.
π‘ Solution:
β Clean or replace air filters every 1β2 months.
β Check filters more often in dusty environments like Quakers Hill or Acacia Gardens.
3. Damaged or Rusted Drain Pan
If your air conditioner unit is leaking water inside, the drain pan could be cracked or rusted, allowing water to spill onto the floor.
π‘ Solution:
β Inspect the drain pan for damage.
β If itβs rusted, replace it with a new one.
4. Low Refrigerant Levels
Low refrigerant causes ice buildup on the evaporator coil, which melts and creates excess water. This can also make your air conditioner less efficient.
π‘ Solution:
β Check if your AC isnβt cooling properly.
β If you hear a hissing noise, it may indicate a refrigerant leak β call Climashift Pty Ltd
5. Incorrect AC Installation
If your air conditioner wasnβt installed correctly, the drainage system may be misaligned, causing leaks.
π‘ Solution:
β Ensure the unit is level.
β If water drips from the back, the tilt may need adjusting.
