We had the air handler replaced a few months ago. It is in the attic and we live in Florida. We had both the original installer and a second contractor back to reseal the plenums. But we are still having a problem with the bottom of the air handler sweating. If I dry the bottom of the air handler and then go back later to look, the first place I see drops is near one of the rubber bushings that is between the top of the support rail that holds the unit up and the bottom of the cabinet (the unit is suspended on chains from the rafters).
I have two questions. First, is that bushing a potential source of an air leak (is it screwed into the cabinet)?
Second, am I correct to assume there should be no condensation, at all, on the outside of the air handler cabinet?
Thanks, in advance, for any replies.
