Tjernlund UnderAire Crawl Space Ventilator - Deluxe Two-Fan, 220 CFM, Model# V2D Review

Average Reviews:

(More customer reviews)I purchased this for my crawl space a few weeks ago. We've had dampness issues and with all the Atlanta area flooding/rain, I figured it would be an asset. I'm sure it is doing some good with air movement but it's so darn loud despite having exchanged it once already and making sure to install it to manufacturer's specs. From the reviews I had read, I expected to not hear this at all. However, in my essentially ranch style home with a 3-4 foot tall crawl space, it's as loud or louder than my A/C. Even my wife who normally thinks I blow things out of proportion and am too sensative thought it was just too noisy, especially at night.

I'll probably move it to the a far corner of my home and set it for "biblical floods" only, the humidistat at 80 percent or higher. I'd give it one start but I'm sure it is moving air under the house, so it's probably doing 2 stars worth of good-but at a price.
