Why am I getting moisture from my indoor evaporator unit?

Most units have a drain pan. At time of installation a mini split air conditioner needs to be angled a ¼” down towards the drain line to help empty the drain pan. Window units need to angled a ¼” from front to back. Ductless systems use gravity to drain condensation, which is a byproduct of air conditioning. Make sure that the drain pan can properly empty by angling the unit.

Things to check if my unit is properly positioned:
A. Check the drain line for blockage (dirt, leaves, etc.). If you have a blockage take the line off the unit and clean.
B. Check to make sure drain line is connected to unit properly.
C. Check for cracks or holes in the drain line.
