System off upon arrival. Turned it on to test operation. Inspected drain line, it was clear. There was blockage at the end of the line at floor drain though. Cleared that, system then started to leak water after 10 to 20 mins of run time. Water was spraying off the coil and around it because evaporator coil is dirty again. Due to age and condition, replacement is the best option. Collected half down, 5840.50. Remainder with be collected when work is completed next week Thursday.
