    Slime on fins for coil/drippimg water
    I have a site built house that has part of it's unit outside and part inside. The part inside is a vertical housing that goes up to the over head crawl space where the duct work is and has something similar to a car radiator behind the air filter. This "radiator" keeps collecting slime and begins dripping water onto the floor and eventually gets the hall carpet wet. And this morning I woke up to a very humid house. The A/C is cooling the house but this problem is persistent. Can someone tell me what the problem might be?

    That is a nasty situation and the condensate removal system seems to be non functional (Cloged up)along with the coil being dirty and in serious need of professional cleaning. The slime as you call it probably consists of mold/mildue and possibly Legionellosis type bacteria or other health concern nastys.

    I suggest you contact a local HVAC professional to clean the coil and drainage system. At that time they may offer you some treatment tabs(chemicals) that will be placed in the coil drain pan area to help prevent this from happening again.

    Do not delay in the professional cleaning of this area. You are breathing the air being discharged from this unit.

    The high humidity you are experiencing is directly caused by the lack of proper moisture removal.

    Here is a small note on just one type of sickness that can be caused by the system in your home.

    hvac1000 is right on the money on this one. Also ask the service company what the cost would be to put a secondary drain pan under the unit with a float switch that shuts the unit down if the primary drain is clogged. On many coils there is a primary drain and a secondary drain on the pan. Too often I have seen installers cut corners and not connect the secondary drain which may have helped with the initial clog if it was in the pan. But please get this unit cleaned asap. You also may want to check your homeowners policy to see if this water damage is covered.
