If there is water in the system, the expansion valve could be
freezing up, true. One of the things not listed as being replaced is
the drier.

I know (several years ago), when the GoldBrick's AC system was
getting switched over to R134, the evaporator had gotten clogged up
with some black junk. Never understood what it was, the dealer
replaced it (they also swore that they had cleaned the system prior
to switching oils...)
