    Yes, but since it is a zoned system, perhaps not really. That is one thing I want checked out is that when some zones close down, some or completely, that the blower and stages throttle accordingly.

    Seems would also be a major issue with ducting them in parallel rather than just putting one under the air handler. I would not have the room for that so guess I'm sol on that arrangement.
