    2 Story House 1 Air Handler on 1st floor....1 on 2nd floor

    ??
    O.k.
    Now...I keep hearing different things about ...only using one air handler in the basement ...to cool the entire house..
    zone dampers anyone ?

    I have found in my... 19 yrs of service work...it works best if you have..
    2 systems ...
    one for each floor....
    or
    zone dampers..
    But....where is the cost savings
    or is there ?
    and what happens ...when both floors are calling ?
    Keep it simple
    Air Handler......for each floor

    Both methods work, and both methods have their pros and cons.

    2 units: Cost more to insall, twice the maintanence cost. Redundency if one unit breaks down.

    1 unit zoned: Cost less to install, better whole house air circulation during milder temp days. Over sized for any 1 zone.

    How many times must one fix something before it is fixed?
