Diagnostic completed. On arrival client reports water entering downstairs unit through suspected condensate line failure. Gained access to downstairs unit and found several access cuts into closet wall behind air handler. Condensate line exiting upstairs unit has broken inside wall and is draining into wall cavity. Line is being diverted into bucket downstairs. Two options for repair are opening wall to replumb condensate line or, more preferably, to run 3/8 copper line through attic and out of second floor unit to ensure proper evacuation. Discussed with client who will communicate when ready to proceed with repair. No further action necessary at this time.
