Am interested in others' solution to this problem...if you have it. We live in the very humid south. The AC ducts under my house drip with condensation July August and September. A couple of years ago, a "guy" told me to close my outside vents and leave them closed all year. I did that. Well...it just so happens that was also about the time I started seeing some inside mold on the ceilings in that area. This has happened each year for about the last 2. Usually if I wipe the mold down with bleach it doesn't reappear.
BUT...I'm tired of this so ....am thinking about 2 solutions. One involves what is called a "Conditioned Crawl Space", the other is to simply put dehumdifiers under the house.
The theory around the Conditioned Crawl Space is to seal everything up ...including vents.....with plastic and foam insulation- sealing the outside humid air outside and preventing it from coming in. Next is to route a vent or two from the HVAC system under the house - making the crawl space feel like the inside of our house. Theory is my AC duct work under my house will not form condensation. With this solution there also should be some dehumidfication that is a normal part of AC functioning.
I'm concerned about the dehumidifier equipment solution.......as they become "another" piece of equipment to maintain. I need two. With this solution, the vents also have to be sealed and plastic used up the walls as well.
How have others solved their humid moist crawl space issues
