6 Causes of AC Water Leakage

Contents

Air conditioner dripping often affects relationships with neighbours above and below. To address the problem, we must first identify the cause. This article explains the reasons for air conditioner dripping so your AC can continue to be a relief in the hot summer. Leakage or dripping usually has the following 6 causes:

1. Installation factor: If the indoor unit is not installed properly, the drain pipe position may obstruct drainage. It is recommended that a professional inspect and adjust the position.

2. Poor drainage in the drain pipe: an aged or bent drain pipe may cause poor drainage and lead to dripping issues. Replacing the drain pipe alone can solve the problem.

3. Insulation material ageing: If the pipe insulation is too thin or aged, temperature differences in the pipe may cause condensation. It is recommended to have a technician inspect it and re-wrap the insulation layer.

4. Dust buildup on the dust filter: too much dirt and dust on the filter will affect airflow, increase the load on the air conditioner, and indirectly affect drainage performance.

5. Blocked drip tray/drain pipe: a blocked drip tray or drain pipe may prevent condensation water from draining away. Check first whether the drip tray/drain pipe is clear and whether the drain pipe is properly connected to the AC. Cleaning the drain pipe can restore proper flow.

6. Blocked heat exchanger: If the heat exchanger is too dirty, it may affect AC operation and drainage efficiency. Professional cleaning is recommended.

If the air conditioner has a water leakage problem, professional assistance is recommended. Improper dismantling may damage components, so it is advisable to have a professional repair team inspect and handle it.
