It is not comfortable working in a garage in the summer when it is hot and no air moving. I mounted this fan on the back wall of one of my garages and it osculates to encompass the entire garage. It feels good when that fan hits you with a blast of air. It does have a cooling effect because trapped heat in a garage builds up. Open the garage door and put this fan on for a bit and the hotter air that has built up goes out the door. It does not cool but has a cooling effect by pushing the air that was built up with the closed garage door and any breeze is better than dead air. It is well worth the purchase and easy install. It also has 3 speeds, and I've found that after a bit that I lower the speed. If I find that I am working only in one spot, I turn off the oscillation when it gets to the area I am working in. Not heavy but well built.
