    Zoned system - layman

    I've read that you shouldn't buy a HVAC system that is too large for your house.

    But, if you have a zoned system, and you turn off the zone for one floor in a three story house, doesn't that result in the same problem--two large a system for the remaining floors?

    Thanks,

    The short answer is no...if designed properly.

    Someone will be along shortly to go more in depth if you desire...but wifey says I gotta go to the grocery store right now

    most zone systems incorporate a bypass damper, as well as a discharge air temp. sensor

    when set-up properly the system will deliver proper CFM

    as well as having overcooling or overheating protection
