3rd AC

[LaydBack]

I'm basically contemplating dual panes vs third AC unit with a heat pump. I'm thinking if I have the dealer install the 3rd AC, I would have them actually put it where the bedroom AC is, and move the factory bedroom AC to replace the vent fan where the 3rd AC goes. That way I could have the 2 heat pumps on the duct system. I'm just wondering if the rear bedroom unit is taller and would present a height issue on the 3731.
