Depends on line set and indoor coil match.
I wonder if it's a R410A unit. With R22 I hardly ever ran into a TXV problem. Seems like more frequent failures with the R410A.
It's an R-22 system, circa 1996. The tech said the same thing: he rarely has problems with the R-22 systems, but often replaces various sealed-system parts on the R-410 units because of the higher pressures.
