I am doing some work in my crawlspace and it is starting to look really nice, if such a word can be used for a crawlspace. It all started with sagging piers and girder. The house is from the 60's and there is only one girder supported by 4 piers. There was rain water coming into the crawlspace and making a mess. A sump pump was installed and now the crawlspace seem to be stabilized. 10 24" footings will support two girders, one on each side of the old one. I got rid of all the crap that was there, left by others in the past few decades. I bought two crawlspace fans, rated at 220CFM each one. These will be installed soon.
Even with all improvements, the crawlspace is still damp and smells musty. I was wondering if a dehumidifier would be too much or not. Would it bring any real benefits, since all HVAC equipment is in the attic? The CS is not encapsulated. I was thinking of getting the remote panel so I would not have to go down to have access to it, but it seems these dehumidifiers need to have the filter changed every 3-4 months. Does that mean that once a dehumidifier is in the CS, I'd have to go down anyway 3-4 times a year? As I already have a sump pump installed, the drainage for the dehumidifier would be fairly easy. This is the type of dehumidifier I had in mind:
