II. Understanding the Split AC System
Before we dive into the common causes of water leakage from split AC units, let’s take a moment to understand how these systems work. A split AC consists of two main components: the indoor unit and the outdoor unit.
The indoor unit, also known as the evaporator unit, is typically installed inside the room you want to cool. It contains the evaporator coil, which is responsible for absorbing heat from the air. The outdoor unit, or the condenser unit, is usually placed outside the house and houses the condenser coil and the compressor.
When you turn on the AC, the compressor in the outdoor unit pumps refrigerant to the evaporator coil in the indoor unit. The refrigerant absorbs heat from the indoor air, causing it to cool down. As the warm air passes over the evaporator coil, the moisture in the air condenses and collects on the coil.
This condensed moisture, also known as condensate, is then drained away through a drainage pipe. However, when something goes wrong with the AC system, this condensate may not be properly drained, leading to water leakage. Now, let’s explore the common causes of water leakage from split AC units.
III. Common Causes of Water Leakage from Split AC
A. Clogged or Dirty Air Filters
One of the most common causes of water leakage from split AC units is clogged or dirty air filters. Air filters are responsible for filtering out dust, dirt, and other airborne particles from the air before it enters the AC system. Over time, these filters can become clogged with debris, restricting the airflow.
1. Effects of Clogged or Dirty Air Filters
When the air filters are clogged or dirty, the airflow to the evaporator coil is hindered. This leads to a drop in temperature, causing the evaporator coil to freeze up. As a result, the ice melts when the AC is turned off, leading to water leakage.
2. Preventive Measures for Clogged or Dirty Air Filters
To prevent water leakage due to clogged or dirty air filters, it’s important to regularly clean or replace the filters. Check the manufacturer’s instructions for the recommended cleaning or replacement schedule. Keeping the air filters clean allows for proper airflow and helps maintain the efficiency of the AC system.
B. Blocked or Damaged Drainage Pipe
Another common cause of water leakage from split AC units is a blocked or damaged drainage pipe. The drainage pipe is responsible for carrying the condensed moisture away from the evaporator coil and out of the AC unit. If this pipe becomes blocked or damaged, the condensate cannot drain properly, resulting in water leakage.
1. Effects of Blocked or Damaged Drainage Pipe
When the drainage pipe is blocked or damaged, the condensate accumulates in the AC unit and eventually overflows. This leads to water leakage and potential damage to the surrounding area.
2. Preventive Measures for Blocked or Damaged Drainage Pipe
To prevent water leakage due to a blocked or damaged drainage pipe, regular maintenance is crucial. Inspect the drainage pipe for any blockages or signs of damage. Clear any debris or obstructions and repair or replace the pipe if necessary. Regular maintenance helps ensure proper drainage and prevents water leakage.

They will ensure that the unit is installed correctly, including proper positioning of the drainage pipe and adequate insulation around the evaporator coil.
D. Low Refrigerant Level
A low refrigerant level in the AC system can cause the evaporator coil to freeze up, leading to water leakage when it thaws. Refrigerant is responsible for absorbing heat from the indoor air, and if there is not enough refrigerant, the coil may become too cold and freeze.
1. Effects of Low Refrigerant Level
When the refrigerant level is low, the evaporator coil can freeze, causing water leakage when it melts. In addition to water leakage, low refrigerant levels can result in reduced cooling efficiency and increased energy consumption.
2. Preventive Measures for Low Refrigerant Level
If you suspect a low refrigerant level, it’s best to contact a professional HVAC technician to inspect and recharge the system. They will be able to identify any leaks in the AC system and recharge the refrigerant to the appropriate level. Regular maintenance and inspections can help prevent water leakage due to low refrigerant levels.
E. Frozen Evaporator Coil
A frozen evaporator coil can also contribute to water leakage from split AC units. When the evaporator coil freezes, it restricts the flow of air and causes the coil to accumulate ice. Once the AC is turned off and the ice melts, water leakage may occur.
1. Effects of Frozen Evaporator Coil
When the evaporator coil freezes, it restricts the airflow and reduces the cooling efficiency of the AC system. This can lead to uneven cooling and discomfort in your home. Additionally, when the ice melts, water leakage can occur.
2. Preventive Measures for Frozen Evaporator Coil
To prevent the evaporator coil from freezing, ensure that the air filters are clean and the airflow is not restricted. Additionally, maintaining proper refrigerant levels and adequate insulation around the coil can help prevent freezing. If you notice any signs of a frozen evaporator coil, it’s best to contact a professional for inspection and repair.
