Condensation On Plenum

[richmod]

Any uninsulated plenum in a non conditioned space is going to be creating a small flood, not just a little condensation.

It's not just a little condensation - the whole plenum is covered with condensation, and there is actually a small pool of water under it now, though not a flood.

If its cooling fine, chances are he's got a humid crawl.

And yes , it probably is a duct lined plenum with a few air leaks.

I'm in North Carolina, so yep - pretty humid down there right now. And yes - it is duct lined - 2 zone ducts, bypass duct, and return duct.

Tech's coming next week - thanks for all the info and opinions.

My plenum is in the attic. It is insulated in the inside with insulation. I don't notice condensation all the time, just some times. Should I be concerned or does this just happen sometimes?
