The AC is also the only air exchange happening in the room currently. Other then that its pretty well sealed.
ShibaSpeak Reviewed by ShibaSpeak on . Portable AC creating too much negative pressure. HELP I have a single hose portable AC inside my medical grow room built inside my garage. The problem is its creating too much negative pressure and due to the garage being so hot the air it is bringing in is causing the room not to cool well. Should I move the AC outside the room and duct the cool air in or something else? Please help. Rating: 5
