crawl space ventilation
Is there a reasonably priced crawl space ventilation exhaust fan for a 250sq ft area? Or is there something better?

Before you try to find and install a fan for the crawlspace, check your vents and make sure they're clear - including outside. If you have bushes, shrubs, or ivy (god forbid!) you might be obstructing the air flow. Ivy can be a nightmare! It grows under the house and will even get into the walls.

Im with Awesomedell you dont put a exhaust fan in a crawlway. If you go to a .gov post They will tell you the same thing. Seal it up . Put a 6 mil poly on the ground 2' over lap and tape the seams. Poly up the wall 2' then a 2" or 3" polystyrene on the walls. then cut out R 19 blocks of F/G put this in the joist on the sill plate all around the home. if you have heat duct down there cut a small out let and return in it. This way the crawl works as a heat sink for you. If you put a fan down there you are looking at one wet mess
