I have two questions/ concerns. 1) the shaking of various rooms in the house is much Improved, but there is still a little. Is that to be expected? 2) the installation crew was unable to fit the dehumidifier under the center of the house due to lack of clearance as I understand it. So they put it very near the back end of the house. Will it still be able to adequately keep the crawl space dry working at the far end of the house? Thanks.
