What say Yee about an air conditoning register in the center of a garage ceiling? this is obviously an homeowner addition, as it is a 4 inch duc with a non adjustable register plate in the center of a 2.5 car garage, it is certainly not enough volume to adequatly cool the garage, He is a Corvette nut.
But the point would be under the right circumstances this could allow toxic gas(carbon dioxide, etc) to back flow into the house. unlikely but possible.
So What say Yee, or Yall, depending on your location.
