The air conditioner is leaking and the reasons might be the following :
Drain line blocked
A blocked condensate drain pipe is most likely to blame if your air conditioner leaks into your home. Debris, such as dirt, dust, or mold, can plug this line over time.
Water cannot escape and drain to the outside of the home when your condensate drain line becomes clogged.
The filter can be clogged
A clogged filter might prevent air from passing through the unit’s evaporator coil. The coil becomes extremely chilly and might start to freeze when the air supply is cut off.
The Refrigerant Level in Your Air Conditioner is Low
The pressure inside your air conditioning system decreases as the volume of refrigerant decreases. Your evaporator coil may potentially freeze, resulting in a dripping mess.
