Anyone try this before? I have an oversized mini split working in one room. I have another room that I am considering cooling with the same ac. Between both of them, the AC will still be big enough, just not sure about moving the air back and forth. Was thinking of running a 6" into the room and a 6" pulling out of the room. Tons of oscilators so I assume the air will get mixed in well before eventually being sucked back into the room that is being actively conditioned. Sort of guessing other room will run a couple degrees hotter.
