I am in Missouri I run a dehumidifier 24 seven 365 in the shop.
Run the mini-split when needed. just make sure you have good insulation.I recently moved from PA to Florida and am in the process of buying a house. Since basements in Florida are called swimming pools my shop will be in part of the garage. To be able to work in the shop during the hot and humid summer months I plan to partition the garage and install a mini-split air conditioner. With that as a background, my question is, if I only run the air conditioner when I'm in the shop, and turn it off when I'm not, which can be for several days, or weeks at a time when traveling to visit the grandkids, will the on again, off again air conditioning, which changes the temperature and humidity in the shop, do any damage to wood stored there? I keep all cast iron surfaces well waxed so i'm less concerned about the machines.
When I was in PA I always stored wood in my basement for a while before working with it so it could acclimate to the temperature and humidity in my basement shop. That wouldn't be the case here. I normally make small things like cutting boards, jewelry boxes and the like. How much trouble would I get into with this approach? I'm concerned that running the mini-split 24/7 for 4 or 5 months every year will get expensive.
As always, thanks in advance for your help and advice.
Since my original post I've managed to live with and adapt to the humidity in Florida. I can't really afford to insulate and air condition the garage. Since most of the larger pieces that I make, tables, cabinets, etc remain in Florida I find that the humidity isn't really a problem other than in the summer when I don't spend much time in the shop. For smaller pieces that I send to friends, cutting boards, coasters, jewelry boxes, small step stools, etc, no one has reported a problem. Between getting older, and a back operation earlier this year, my time in the shop is limited to a couple of hours a day and I don't see that changing in the future. If I were looking at another 20 years in the shop I might consider biting the bullet and go for an air conditioned shop but I'm not. I'm hoping for another 5 years or so, so I'll live with what I have.Given the amount of time that has passed since your initial post on this thread, I hope your shop is doing great. Obviously, although our opinions are welcomed, I guess that due to the time that has passed, you've managed to find out yourself if the wood you've stored in your shop has suffered any significant changes or not. I believe that you should use air conditioning and bring the temperature inside your shop as close as possible to the one you've had while living in Philadelphia. This way, it will be easier for you to control the whole process.
