Where to put the air compressor?
Since I had the space I put mine inside it's own little room in my 35'x45' garage. I't's 5.5' x 4' x 7.5' with an insulated exterior door and threshold. The interior walls and ceiling are also insulated. I can only hear it (barely) when there is no other noise. I allowed a little extra room for storage and a makeshift urinal.
