    Hello all:
    My contractor said I don't need a separate expansion valve because the coil TXCO36S3HPD already comes with one...
    but I see the expansion valve being referred to as TXV and was wondering if the coil above has it.


    My configuration:

    American Standard
    80% single stage 100k furnace: AUD100C936K
    12SEER 3 ton heat pump: 2A6H2036A100A
    High efficiency coil: TXCO36S3HPD
    Humidifier: AHUMD200
    ACONT802 (7-Day Digitial Programmable 3 Heat / 2 Cool)
    Aluminum Chimney Liner kit
    Fossil fuel kit
    condensate pump

    so only TXV* coils have expansion valves?

    In that case should I be asking him to add this to the configuruation? Is an expansion valve an addon - or is it part of the coil?

    I'm confused now.

    No, the TXC-S series coils are Trane's highest efficiency models and come factory with a non-bleed TXV installed.

    I believe that all trane coils being made today have TXV's.
