After running them for a weekend, I discovered another issue. I found in hot temps, the living room area was about 85* and the bedroom was about 68*. The rear air and the ducted AC’s were cooling the back better than the front. I changed my intake grilles to the Coleman “chill grill” with the direct downward air dumps. This pushes the majority of air right out of the front 2 units into the living room/kitchen area and the rear 3rd AC cools the bedroom. There is still some air you can feel thru the ducted vents, but this balanced my cooling and makes everything average out better.

Thanks for the insight!
