There are a few reasons that cause the leaking and dribbling of the unit. Here are some of them:

Air Leakage 

• It is maybe the most generally perceived cause that might lead to the aircon spilling and streaming water. For perfect capability, the air reaching the spilling must pass through the opening. Misguided causes might prompt the spilling of air. The air doesn’t pass through the opening as it should. Regardless this doesn’t happen, likely the air is leaking which leads to flawed working.
• To certify whether you’re experiencing an air spillage, you should do central exploring by taking a gander at the equipment to see whether there is leakage of air through the knits around the opening. In case there is an air spillage, you must take steps to resolve the problem and stay away from additional spillages from happening later on.

Impeded aircon filter

• It is another reason for an aircon leaking and drooling water. When the air filters get obstructed, it hinders the movement of air in the unit. This will become the reason for the freezing of the air, in addition when you turn off the unit or in the case when the best temperature is gotten, ice made on the filter starts softening. The water comes out of it and the unit starts leaking.

Grimy Aircon Filter 

• In case the filter is blocked up or messy, airflow to the evaporator gets hindered, in this manner resulting in a loss in temperature. If the loop turns out to be excessively cool, it gets freeze. When the system is turned off, the inside unit will quit drawing air to the inside, which at that point prompts warming and consequences in the softening of collected ice. If this softening ice blocks up the volume of the dribble tray, it prompts the leak of the water.
