1.0 out of 5 stars Not reliable, September 2, 2009

I removed all my old vents and installed 8 of these on my house. Before installing them I tested them in the freezer, 1 did not work properly, so I returned it and installed the rest. At the first temp change 2 did not perform, I pulled them out and returned and replaced them. Right now it is 71 degrees outside 4 are open and 4 are closed. I wish I had my old manual vents back, but I had to destroy them to get them out. As it is there is no way to open the closed ones to ventilate, and worse, in the winter there is no way to keem them shut, even manually. Dont waste your time with these.

I bought these because the panel that had my crawlspace vent had fallen apart and I a raccoon had decided to move in. I bought 2 and built a replacement panel. I was about the install it when read up more on venting crawlspaces. It seems that building inspectors are re-thinking foundation vents, at least in any area that has humid summers. Venting in the winter in most places is useless, when it is cold crawlspaces tend to be fairly dry and the cold winter air is poor at removing moisture anyway. In summer, hot, moist summer air going into the cooler crawlspace will condense and actually add moisture. Most people are realizing that closing off the crawlspace is usually the best solution. If the crawlspace is next to a basement, you could connect them with vents (after sealing the crawlspace to the outside) to have it part of the basement airspace. A vapor barrier (plastic sheeting on the floor) is great for keeping moisture from the ground from rising into the crawlspace.

So research it before you buy.

I ordered these as replacement for manual units and love them. I had a minor issue with a few of them and one call to the manufacturer and it was taken care of well above my expectations. I highly recommend.
