Sweating A/C ducting making crawlspace damp
Planning to replace the existing vapor barrier in my crawlspace (6mil plastic on sand/dirt floor). While inspecting the space I had to crawl thru small puddles of water on the existing plastic. The moisture was coming from sweating insulated flexible A/C ducting. It was a hot & humid day, and the space is unconditioned. The hoses did not feel much cooler than anything else in the crawlspace, but all of them were dripping (there are a lot of them).
Are the insulated ducts not insulated enough?
What, if anything, can or should I do to decrease the amount of water accumulating in this space? I am not considering encapsulation.
