    Lightbulb Thoughts on Replacing the Heat Pump (Outdoor Unit) Flowrater to TXV

    I am going to replace a leaking (Goodman) flowrater type indoor coil with a new direct replacement Coil with a TXV, which is also from Goodman. Since I'll have the system opened up, I've thought about also replacing the Flowrater on outdoor coil (12 seer) heat pump with possibly a universal type TXV kit. (No kit is available from Goodman to upgrade the outdoor unit with a TXV.)

    Does anyone believe that it is worth the trouble of trying to change the outdoor unit's flowrater with a TXV?

    Thanks in advance for your response!

    Nope.
    The outdoor TXV doesn't run the same SH as a TXV for an indoor coil.
    Much more headach then it is worth.

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

    Indoor TXV needs to be for heat pump duty (built-in check valve).

    I'll take your advice and keep the job simple and just replace the indoor coil. And yes, I am planning on getting the bi-directional check valve (heat pump) type TXV.

    Thanks for your response beenthere and shophound!
