Yes. I have the crawl space sealed up as well as humanly possible. I did that after much research and discussing the problem with mold experts and the tech support people at Aprilaire. They advised me that most moisture in a modern home (especially if they have insulated windows and are wrapped with tyvek or similar material) comes up through the ground and then rises through the house; It's very hard to provide a complete vapor barrier to all below grade areas. When I purchased the Aprilaire 1770 unit, I had planned to hook it into the HVAC system (to draw air from the house), the tech support said that probably wasn't needed in my scenario...he advised me to try it as a free standing unit and if that didn't work I could always incorporate it into the system. He was correct and it works well on it's own. That may not be the case in every setup, but it works in mine.
