Performed a tune up on system. Poured 1 gallon of water through drain and water drained normally. Did find that unit did not have any water safety installed. Tested pressures and amp draws on outdoor unit and all were good. Tested capacitor and found capacitor to be dead. Previous company had installed a supco hard start on unit and hard start was giving high readings. Cleaned off outdoor coil inside and out. Recommended to customer that drain switch and/or a new capacitor would be needed. Found no other issues at this time.
