hanging a dehumidifier

KaiserRoo | Posted in General Discussion on June 2, 2007 09:32am

I’d like some help on the best way to hang a dehumidifier in my basement so that I don’t transmit noise and vibration from the unit to the floor above. Any other advice that may help me in this project?

Thanks in advance, KaiserRoo

    I'd just unplug it -- I don't think it's necessary to execute it.

    (Hang it like you'd hang any condemned -- with rope. A plywood platform with a piece of rope in each corner, running up to a screw eye in the joist above. (Study how to make a figure-eight knot.) Put some sort of curb on the platform or otherwise fix things so the unit won't vibrate off.)

    So convenient a thing it is to be a reasonable Creature, since it enables one to find or make a Reason for everything one has a mind to do. --Benjamin Franklin

    I've really only put these in a basement and my workshop. In each case, I used "L" brackets to support a shelf. The brackets are attached to the wall in your favorite fashion. My workshop, for example, has block walls, and the bracket are secured with screws run into plastic wall anchors. I had one attached to standard stud&rock walls at my old house. I suspect (but don't positively remember) that the brackets were screwed to the studs.

    In the old house, I placed a square of plywood on the brackets to support the unit. In my workshop, I have two pieces of 1x2 laid across the brackets.

    Neither unit makes (or made) enough noise to be heard in the room above it. The one in my workshop can be heard in the adjoining room, but not in the rest of the house.

      Thanks for the info now I'll have to clear a spot in the corner for both power and draining.

        I drained the basement unit into a sump pump. My workshop unit is drained through the outside wall (1/2" PVC).George Patterson

    Once on TOH I saw them hang a garage door opener on cut up pieces of tire tread to break the transmission of noise to the bedroom above. If it worked for a garage door opener, I can't imagine why it wouldn't work for a humidifier.

    Good luck.

      I want to thank all of you for your input on this, KaiserRoo

        Check out a good HVAC supply shop.  They sell all kinds of vibration dampeners made from rubber and neoprene.  You can use some on the hangers and some under the dehumidifier to increase the isolation.

    I appreciate the help you got with your question, but I suspect that you may be almost breaking Man Law # 228c, that is worrying that you might disturb a neighbor who really doesn't care that his kids play their CDs at midnight. Just how much noise does a dehumidifier create?
