Units leak water
Possible cause
Solution
Evaporator units are not level
Evaporator units should be level on the wall to prevent leaking
Drain lines are clogged or kinked
Check drain lines to make sure water can flow freely
Drains are clogged, preventing water from escaping
Disconnect drain lines and clear them out; check drains for blockage
Drain lines do not have a downward slope
Fix drain lines so there is a downward slope from the unit to the
drains
Coils are iced, causing drain pans to freeze and water to overflow
Melt ice with blow drier. Soak up water with a towel.

Possible cause
Solution
Lack of airflow
