    First of all, you need a professional diagnosis on what your problem is.

    I realize looking back is 20/20 but it seems it was a poor decision to replace an air handler new on an 18 yr old outside...

    I would want to see all model numbers of equipment proposed in each quote. I agree that you get best comfort and control from separate systems over zoning.

    However with that said, Carrier has...

    Thought so. You are undersized on cooling, oversized on heating. You need a return on third floor and ductwork system needs balancing.

    I would upgrade the Bryant quote to the Preferred 13 Mdl 123 AC condenser. More comparable to the Trane XR13 condenser. And again, I believe you are being oversized on the furnaces.

    Furnaces oversized. You need a load calc especially for heating size. What are these dealers thinking?

    I wouldn't be happy at all that an ADP coil was installed.

    Several questions though.

    Do you have an AHRI matching number with that coil?

    Does it affect warranty? Trane coil would be 10 yr.
