Arrived t9 home for mini split leaking water on downstairs head in office. Client has lived in the home for 2 years and has not had it serviced. He turned it on and immediately it began dripping water from the opposite side of the drain port. We turned it off an I could immediately see the unit had excessive debris and dust accumulated on it. I believe the unit to have multiple issue caused from it being dirty. The coil was potentially freezing over and the drain line was clogged due to the excessive debris it was trying to push out. We discussed different option to clean the unit and join our maintenance plan. Our client elected to only clean the unit today. I took the unit part. Cleaned and serviced it and reassembled the unit. Once cleaned and assembled we tested the unit. It did not drip any water and it began cooling properly.
