Both of my shops have a high moisture problem largely from not having a moisture barrier in the floor (a mistake I will never make on a building again). I have to provide positive ventilation when not in use just to keep excess moisture out. That can be a trick in spring and fall when temps fluctuate wildly and stuff wants to sweat as temps change. In this heat the humidity gets so high that the air in the shops is chokingly hard to breathe. Between that and standing there streaming sweat I only work in them in short bits of time.
Even though it looks like the 90°+ temps will moderate later this week I have decided to give up and set up an AC in the woodshop. The farm shop in the converted barn is pretty much hopeless as far as AC but I do have several large fans I run in there and try to work in there early in the day. Still it is hard to want to.
I have been dragging my feet on putting the window AC in the woodshop hoping that a few good sized checks (running late) would come in and then I would feel that I could buy a new or newish higher efficiency AC unit for it. I have an AC that is an older unit but it is so heavy that it may need 3 guys or a fork-lift to install it. It is also old enough that it probably is not very efficient but at least it is a 220V unit. I'm not even sure it runs yet as it has been stored for about 3 years. Of course if I decide to use it I will test it first. I would hate to go to all of the work to put it in and have it fail quickly. Then again a new one can fail... but a new one wouldn't weigh a ton.
How many of you are running AC in your woodshop? How many are just staying in the house?
