Insulating Ducts in Crawl Space
#1
The ducts in my crawl space are dripping from the AC. Of course, there is only dirt below the ducts which is asorbing all of this moisture. How do I insulate the ducts, what material do I use? Do I need to have the AC checked? Also-do I need to put down some type of barrier on the dirt floor of the crawl space? Any info. would be greatly appreciated!!!! A Crazy Woman in KS.

Condensation on AC ducts/water pipes in the crawlspace is from air and ground humidity. Insulate ducts (do NOT run an AC duct under your house), calculate the cubic footage (heighth X width X length) of crawlspace, and install an exhaust fan of sufficient cubic-feet-per-minute capacity in crawlspace opening and open other vents wide. Check with someone like W. W. Grainger for recommended fan size. Much more energy efficeint. In KS, it may be more from ground moisture, and a vapor barrier on crawlspace ground may help, also. Good Luck!
