An AC (split 1.0 ton) leaking water from the indoor unit can be caused by several factors, including:
Clogged Drain Line: The indoor unit of an AC has a drain line that carries away condensed water. If the drain line becomes clogged with dust, dirt, or debris, the water may accumulate and eventually overflow, causing a leak.
Improper Installation: If the AC unit was not installed correctly, it can result in improper drainage. This can lead to water leakage from the indoor unit.
Frozen Evaporator Coil: If the evaporator coil inside the indoor unit becomes frozen, it can cause excess water to build up when it thaws. This water can then leak from the unit.
Low Refrigerant Level: Insufficient refrigerant in the system can cause the evaporator coil to freeze, leading to water leakage when it melts.
Running the AC in this situation is not recommended as it can exacerbate the problem. The water leakage can cause damage to your walls, floors, or any other items near the indoor unit. Additionally, the AC's performance may be compromised, leading to reduced cooling efficiency.
It's best to turn off the AC and wait for a professional HVAC technician to inspect and repair the unit. They will be able to identify the root cause of the leakage and take the necessary steps to fix it. It's important to address the issue promptly to prevent further damage and ensure the safe and efficient operation of your AC system.
