I recently moved to a new house, and am re-establishing my shop in the 2-car garage. Similar to my last shop, it has really nice high ceilings (about 12'). I didn't have a ceiling fan in my last shop but was thinking it would be nice to help circulate the air, especially in the winter when the heat tends to rise and it's much colder toward the floor. The only downside I can think of is potentially having the blades hit a long board that I might be carrying through the shop. It would be great to hear from others that have ceiling fans in their shop as to pros and cons.
