With the understanding that dwelling in hot and humid SC during the summer WILL inevitably cause SOME condensation, I have seen some very excessive amounts. I think I have come to grips with the handlers and supplies in the crawlspaces getting a lot of this, but what about the ones that are located indoors? All the supply ducting ran between the floors of a two story house, and this space wasn’t hot and humid. These supplies were just filled with water in some places though, creating leaks and subsequent damage to drywall ceilings and mold. I can’t blame it on the unit and supplies being in a hot humid crawlspace, so where is it developing this? Could it be the installer putting in too much tonnage for the square footage?

On some units, if the condensate P-trap does not have water in it, it will suck air and blow condensate all over the airhandler coil. This gets blown back into the duct and into the house as excess moisture.
I have seen a trane gas pack do this and suspect that many others will do it too.
