    Default A/C Issue

    Having an issue with my A/C the drip pan overflowed and leaked out a vent and along a seam of some sheetrock in the ceiling. Noticed it real quick ran up stairs to attic pan full. I stopped the A/C and checked the overflow drain I guess it's stopped up... Whats the fix here? I can't get an air hose because the unit sits almost on top of the drain / PVC pipe that runs to my sink drain.

    Get a ball valve and add a piece of tubing to it then add an air chuck to the oher side. Snake it under the unit. You can also cut the pvc and add a tee with a long radius.They make them so you can clean the line out. Any good a/c guy would have installed one when they installed it.

    Well heres the damage... Been a fun night.





    2nd photo is 3rd floor below the attic in the master. Water has dripped down the wall to the 2nd floor. 2nd floor ceiling pictured.

    I am baffled how the main drain and backup are both clogged? I can only assume that seeing as I have water stains and all these issues all of the sudden. I turned the AC down to 71 from 6-10 pm problem happened during that time. I've since removed a lot of the water from the pan under the A/C.

    cut that pvc right there above the wood, blow it out and glue a cleanout fitting in place. every once in a while send some bleach down there. that drain line gets slimy gunk built up in it over time. If you can get to where it drains (mine drains outside) -- hook a shop vac up to it and suck that gunk out of there.

    I always use my shop vac to remove the water and algae. Just put the nozzle on the end of the drain line and wrap it with foam or a t-shirt and it will take care of both problems. Pick up some chlorine tabs and toss some into both pans to keep the algae from building up. A float switch will save you from repairs next time.

    It should have had a float switch........ It never was activated apparently or it's not adjusted to the proper height.

    x2, I always pour some bleach through both lines at the beginning of the season.
