In a garage without air conditioning, things can heat up pretty quickly on a warm day. Add a little humidity in a place like Florida in the summer, and it can get downright stifling in your garage. Under these conditions, an oscillating pedestal fan or even a box fan won’t be enough to get your garage to a comfortable level. If you feel a breeze at all, it may just be to blow hot air back on you as you work.
That’s because residential fans are designed to be used in smaller spaces. A two- or three-car garage, on the other hand, can be anywhere between 450 and 1,200 square feet. To cool that type of space — especially if it’s uninsulated — requires a much stronger fan.
