Does AS - TXCO36S3HPD have a built in expansion valve?

[shaum76]

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

TXV coil

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.

thanks for clearing that up. my heater guy really is good.

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