    Confused Water blowing off coil

    A friend has a very nice house in Houston with a couple of oversized air conditioners. He had actual droplets of water being blown off the coil and coming out one of the supplies. Just so I can understand, is there one or two design or install errors which can lead to this problem?


    Thanks -- Pstu

    Some Horiz. coils have splash guards to help prevent this.

    How long have they been installed. Dirty coils can do that. High velocity can also cause it.

    How many times must one fix something before it is fixed?

    I encounter that periodically. Twice last week in fact. I have a spray bottle in the truck with 50%joy dish detergent and 50% water. I spray the coils with the Joy solution while the unit is running and then rinse with water. Stops the problem right away. when I have to pull a coil to clean it I use stronger cleaners but the last thing i do is rinse with the joy solution. I have never had to go back again.
    The joy has a surfactant that breaks the surface tension so the water can run down between the fins into the pan. I;m not sure why it happens. Sometimes the water runs off the coil like it was scotch guarded. hit it with the joy solution and problem solved.

    On a couple occasions I did see coils that had slight icing horizontally in strips and water dripped from the ice.
