I am in the early planning stages to build a 600 to 900 square foot shop next spring/summer.
HVAC is my biggest question right now. The shop will be fully heated and air conditioned. HVAC will be central, not window units or the like.
How do I control rust without pushing my energy bill through the roof? I live in the Minneapolis, MN area so the temps get real low in the winter and fairly high in summer with high humidity.
I don't want to keep the heat over 40 to 50 degrees in the winter except when I'm in there. Will the temp changes cause rust?
I also don't want to air condition under 80 degrees or so unless I'm in the shop. How can I remove enough moisture from the air to keep the tools rust free? I am thinking maybe two A/C units smaller sized so one can run all the time and both when I'm in the shop.
