In early September of 2006 we experienced an air conditioning outage. (It’s still sweltering on Labor Day in Alabama). We had a coolant leak. I believe that the repairman replaced the evaporator. However, during this cooling season there is a lot of water (condensation) all around the pad. The unit has a small pvc pipe connected on the side where the condensation used to drip, but that pipe now stays bone-dry. The bottom of the unit and pad remain wet - mold has started growing around it. I clean up the mold and fungus but it comes back in about a week. I'm worried about rust damage to the unit due to the standing water. Is this a problem? What should I do?
