Potential Causes of Air Conditioner Pan Water BuildupA clogged condensate line will cause water to build up in the drain pan. A few other potential causes of standing water in the AC pan include a frozen evaporator coil and improper AC system-installation.

Where is the drain pan on my AC? Central Air ConditionerThe unit's evaporator coils are located here, and directly underneath those coils is the drain pan. The moisture that the unit removes from the humid interior air condenses on the evaporator coils and drips into the pan. A pipe normally runs from this pan, leading downward to a floordrain.

Why is my air conditioner draining so much water? Dirty air filters– whenyour AC air filter is dirty, partially blocked, or completely clogged, your air conditioner's evaporator coils are more likely to freeze up, causing excess water to overspill from the drain pan. If the drain pipe is blocked, it could cause water to leak from your AC.

Why is my air conditioner leaking water from the bottom? Drain line problems & your AC dripping waterIssues with the condensate drain line are the most common causeof an air conditioner leaking water inside the house. If it gets clogged with dirt and debris (which are carried into the line along with the condensate) the backup can cause leaks or a rupture of the line.
