Portable AC creating too much negative pressure. HELP

[Bloomin Idiot]

The garage is far detached from the house so the only thing I really have to vent it with some days is 115 degree weather. Any suggestions?

to properly cool that space you will need a 3 to 5 ton unit. your current unit is not able to keep the demand in an easy limit. that is why is it going hot to cold on you.
if you are hydroponic chill the water. 115 is hard to deal with indoors. you will need 3-4 times the normal ac to keep up and not have problems.

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
