...Took some foil tape and sealed between the two plenums and it helped A LOT!
I did the same thing, not knowing what I was doing, just made obvious sense to do it since air cold air was being sucked right back into the AC and not forced out into the living space. I used aluminum stove pipe tape (extremely sticky and meant to be used on gas water heater or gas furnace flue pipes). So the tape will never be a problem. Once all the holes were plugged, BIG, BIG change in air output!
Good tip here! Easy fix and costs nothing but some tape.
We changed the older 15k Coleman AC in my in laws camper to a new 15k Coleman and had to tape the insulated divider in. My original plan was to seal off all the holes but after I got the units switched out I wanted to make sure it ran before I did anything else and it blew the divider out. I had to tape it in just to run the unit. Luckily I had a full roll of foil tape.
