Appreciation post: my crawlspace dehumidifier cut my summer power bill by $18 a month
I used to think dehumidifiers in the crawlspace were a waste of a plug and a few bucks a month. Then last August my wife noticed the hardwood in the hallway was cupping near the vent, and I had a guy from Decatur come look at it. He put a cheap moisture meter on the joists and they read 22 percent, which he said was way too wet for July. I borrowed a friend's dehumidifier for six weeks and the joists dropped to around 13 percent, and the cupping flattened out almost all the way by October. What really got me was the power bill, it was about $18 lower than the same month last year even with the unit running, I guess because the AC wasn't fighting all that wet air. So yeah, I bought my own and it runs from April to October now. Has anyone here run one through the winter or do you pull it out once it gets cool?
