Sweating ducts In conditioned attic
Hello all, first time poster here.
I have been renevating our home and one of the steps that I did was add two bedrooms to the attic area and close off the attic and make it a conditioned space.
The roof sheathing has a combination of closed and open cell foam placing R value about R-38, which is good my region.
I had an LG ducted minisplit installed in the conditioned attic space and they used metal ducting in this area.
I was checking on something up there today and found the ducting near the output of the unit sweating pretty badly.
My concern is I may have an air leak in the foam somewhere causing this or should I be tracking down another issue.
Ducting doesn’t have any insulation on it and being conditioned area I feel the contractor didn’t think it needed it.
Any help or thoughts would be greatly appreciated.
