    A/C Air Handler Condensation Leak
    The A/C air handler located in my attic is leaking condensation profusely onto the ceiling below. It is almost a steady stream at times. The drain pipe is open and the drip pan is essentially dry, because the leak is coming from underneath the A-coil, not the outside of the coil. The pan catches only drippings from the outer perimeter of the coil. The "leak" got worse as the humidity increased. The coil has not iced at all. What is causing this and how do I stop it? bwilson1946

    Hard to tell without getting up there and investigating a little. The pan should be larger than the unit in attic. You do have a pan under unit with a safety float switch on it don't you? This is to protect the ceiling in a event of a problem.

    There is actually no "pan" per se. There is only an inch and a half deep channel around the perimeter of the A-frame coil [no safety float] that catches condensation from the outside of the coil. The "leak" is coming from the bottom of the coil where there is nothing but the filter between the drip and the ceiling. Unit was installed 4 years ago and never a problem until now. I am perplexed. bwilson1946.

    Might be best calling a qualified tech in to assess the situation before anymore damage occurs. I wouldn't want to put this repair off. Good Luck

    You probably have a dirty evaporator coil, causing the water to drip off ,normally the condensate will follow the fins of the coil down at an angle to the pan. Wash the coil with a heavy coil cleaning solution and a spray bottle, or have a service tech dissasemble and take out side and wash (best way). Mike
