Common Causes of Leaks
A leaky split AC indoor unit can be a real pain. The good news is that most leaks are caused by a few common issues that are easy to fix.
One of the main reasons for leaks is a clogged drainage pipe. This is because the drainage pipe collects the condensation runoff and moves it to the outside of your home. When it becomes clogged, the condensation runoff will backup and wind up on your floor.
A clogged condensate drain line is another primary reason for indoor AC water leaks. You can use a wet/dry vacuum or a stiff brush to clear any blockages.
Low refrigerant levels can also cause the evaporator coil to freeze and then thaw, leading to water overflow. This is a common issue that can be fixed by contacting a professional to check and refill refrigerant if needed.
Dirty air filters can restrict airflow, causing the evaporator coil to freeze. Replace the filter if it is dirty to prevent this issue.
A malfunctioning condensate pump can also cause leaks. Ensure that the pump is working correctly, and if it's not, it may need to be repaired or replaced.
Proper installation is also crucial to prevent leaks. Ensure that the unit is installed correctly, with no tilting or misalignment that could cause water to leak.
Here are some common causes of leaks in a split AC indoor unit:
- Clogged drainage pipe
- Clogged condensate drain line
- Low refrigerant levels

Troubleshooting and Diagnosis
A low refrigerant level can cause the indoor unit to freeze, resulting in water dripping from the unit. This is because the low refrigerant will cause the indoor unit to freeze, and the ice will then melt, dripping water.
Loose connections, damaged parts, or manufacturing defects can all cause refrigerant leaks. Over time, the seals and gaskets in the system can also degrade, allowing refrigerant to escape.
