I encountered my first Trane muffler.
I almost figured it was just a filter-drier
and was going to cut it out, but at the last
minute called the senior tech and he vaguely
clued me in--"leave it."
Since almost (?) nobody else uses them,
do they really do anything? Has anybody
been to Trane training and received more
info on them? Just curious. I did read the
one thread on here that says they NEVER clog
or anything, to not touch them. Like I said,
I'm just curious.
On that same note of curiousness, the same
unit had one of those tiny copper filter-driers.
(I removed it and brazed in a big-blue bi-directional
on the liquid line.) It was outside of the coil but inside
a side panel on the outside unit. (I say "outside"
because it was a heat pump.) Are these things
inferior to the more common big blue filter-driers?
Does anybody make a point of replacing them with
the same copper type or is a big blue filter-drier
