Dreo did it again ! This is one very cool portable garage AC whole .

Although Coolblus says it will keep spaces up to 550 square feet nerveless — approximately the sizing of many 2 - car service department — we feel it ’s substantially suited to a 1 - railroad car garage or up to about 350 square understructure . Of course , it all depends on the structure ’s insulation degree and the outdoor temperature .
