    I have two proposals for a Bryant Plus 90i Variable Capacity
    Furnace Model 355MAV060100F and Bryant Two-Stage Puron Air
    Conditioner Model 598BNX048000 installation. Each proposal
    offers a different evaporator coil. Coil one is Bryant
    Furnace N Coil -Clear Coat Puron TXV Model CK5PXA048021.
    Coil two is Model CC5AXC048021.

    I'm still evaluating the contractors, so before I ask them
    about this I was hoping to a learn a little bit myself.

    Why would there be different coils proposed?
    Cost? Efficiency? Sizing?

    Coil one is an "N" coil while coil two is an "A" coil.
    What are there differences? Advantages/Disadvantages?

    Coil one is a "cased" coil while coil two is not.
    Differences? Advantages/Disadvantages?

    Coil one has a factory installed TXV. Coil two does not.
    A TXV appears to be a regular recommendation. Coil two
    proposal does not say anything about a TXV. Would I expect
    that no TXV would be installed with coil two? Should I
    have a TXV installed?

    that system has to have a txv or the system will not work properly. never buy a system over 12 seer without a txv, you will not get the rated seer. i would never install any system in my house without a txv. hire the contractor that stated txv.
    smart choice bryant reliant and carrier t series air conditioners are the best in the business bar none.

    That's true.

    That's not true. Many Carrier ODU make their rating without a TEV. Trane on the other hand...

    However, I do agree that a system with a TEV will perform better over a wide range of temperatures and conditions. I always recommend a TEV when approached by a dealer concerned with system selection.
