It has happened that a duct was blocked during construction, or not connected. As mentioned, the ductwork is a modified H design, and both ACs are on the system. It works so that the LR AC exits mainly into the living area, and the BR AC mostly into the bedroom. If you make the effort, when either one of the ACs is running, you should be able to feel a small amount of flow out of the other area ducts.
Do you fully understand the zone system?
