Upon arrival we spoke to the client on the phone. The client stated the unit in the garage attic was leaking water and it was damaging the paint and ceiling in the laundry room. We proceeded in the house and found the leaking ceiling. We proceeded into the attic where we found that the main drain line was clogged and along with the secondary pan drain as well. We vacuumed out the pan, cut the pvc to the main drain line and blew them out with nitrogen. After the line was cleared we reconnected the pvc with glue and tested the drains with 2 gallons of water. Lines flushed out like they should. Unit was cooling properly upon departure. Maintenance will be preformed at a later date. CLEAR DRAIN BLOCK - USING NITROGEN ONLY LEVEL 2 CONDENSATE DRAIN LINES NEED TO BE CLEANED OR THEY CAN CLOG WITH ALGAE AND DEBRIS Includes shop vacuuming when necessary and 1 PVC Coupling Also installation of a Quickblast PVC fitting, which improves accessibility for future maintenance.
