Now that is something a lot of us probably have not checked. I only had one duct that was not performing as the others did. When I pulled the floor register off, the round metal cut out was laying across the duct work, left behind during construction. Obviously, this is the heater register but same principal. The AC ducts on our unit blow you away. We have the 15,000 btu in the living room and the 13, 500 btu in the bedroom. Never thought to check the outlets on the main AC unit.
