When water drips from a split air conditioning (AC) unit, it is usually a result of condensation. The AC unit works by cooling the air, which causes moisture in the air to condense into water droplets. This is similar to how water droplets form on the outside of a cold glass on a hot day.
Inside a split AC unit, there is an evaporator coil that cools the warm air. As the warm air passes over the evaporator coil, the moisture in the air condenses on the cold surface of the coil. The condensed water then collects in a tray or a pan known as a condensate tray, located beneath the evaporator coil.
Ideally, the condensed water should flow out of the AC unit through a drain pipe or hose connected to the condensate tray. This drain system is designed to carry the water away and prevent it from leaking into your living space. However, if the drain pipe is blocked or becomes clogged with dirt, dust, or algae, the water may overflow and drip from the AC unit instead.
Other factors that can contribute to water leakage from a split AC include:
Improper installation: If the AC unit is not installed correctly, it may not be level, leading to improper drainage and water leakage.
Dirty or clogged air filters: When the air filters in the AC unit become dirty or clogged, it restricts the airflow and reduces the cooling efficiency. This can cause excessive condensation and water buildup.
Overcooling: Running the AC unit at very low temperatures can cause excessive condensation and water leakage. It is recommended to set the temperature to a comfortable level and avoid extreme cooling.
High humidity: In areas with high humidity, the AC unit may produce more condensate, and if the drain system is not able to handle the increased volume, water leakage can occur.
If you notice water dripping from your split AC unit, it is advisable to contact a professional technician or an AC service provider to inspect and resolve the issue. They can clean the drain system, ensure proper installation, and address any other potential problems to prevent further water leakage.
