    Confused What do you think?

    Made a sizable investment in a complete Trane XV80 Furnace and XR13 Heat pump system 2 weeks ago. AC failed about 2 days after install. After misdiagnosis- 4 service calls and a new line set- installer discovered TXV on the new indoor A-coil was bad. Installer wants to replace the TXV- is an entire new coil in my best interest? I was told pressure limit switches protect the system, but could other system damage have occured?

    TXV only. That's all that's bad and you won't gain a thing by changing out the coil. Sometimes you just end up with a bad part when you buy something new and that's what the warranty is for.

    Bad TXV won't cause any harm to the coil, so just a TXV is fine.

    Could it have damaged something else, doutbful it did, and if it did, it would show up when they installed the new TXV.

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

    ive never seen a bad txv damage a coil, but if it did your warranty would cover it.

    I am also thinking that there was no protection of the txv bulb during brazing either. Maybe not an equipment failure but an installer failure. It seems that I run across that more than actual warrenty failed parts or equipment.
