Fixed orifice tubes:
If you are working on an orifice tube system
always remove and inspect it. The inlet screen
will provide the best indication of contamination
in the A/C system. Never try to clean the orifice
tube. It should always be replaced when
there is any sign of debris or contamination.
Block type expansion valves:
Block type expansion valves should never be
flushed. If a restriction is suspected, it will have
to be replaced. These valves do not typically
include a protective inlet filter. If a valve
restriction is
replacement.
Thermostatic expansion valves (TXV):
Thermostatic expansion valves could include an
inlet filter. Typically, they are conic and press fit
into the valves inlet. They can be removed and
cleaned. However the valve itself can not be
flushed. If a valve restriction is suspected, it
will need replacement.
Condensers and evaporators:

If some of these orifices are plugged, it is
nearly impossible to clean them and the
replacement of the entire component is
the only solution.
