Can you install a TXV on a set of new coils like the all aluminum coils you can get with a Goodman unit? The best I can tell.... they only come with a "check flowrater" which upon googling that.... It is just a fixed orfice. I really want the TXV but would like to consider a goodman split system......

I assume if I do put a TXV valve in.... the entire warranty is null and void on my entire split system.... no?

 
The flowrater is a fixed metering device. It is designed to drop the pressure from design head pressure to design suction pressure. If you install a TX valve in series with it. You have two devices in series that were both designed to drop pressure.

If you can remove the flowrater orifice, the txv should work fine. if not... stick with the manufacturers design.
 
I ended up just going with the American Standard equipment which comes with the TXV. I appreciate the design of the TXV as opposed to the fixed orfice. Once I read about both of them, I knew which one I had to have on my system.
