Enthalpy charts detail the performance
of the refrigerant as it moves through the
refrigerant system. Learning to use an
enthalpy chart will lead you to the fastest
and most accurate way of diagnosing
a system failure.
In closing, if you experience a compressor
failure and debris has traveled
through the entire system, not only must
you replace the receiver/dryer or accumulator,
but you should plan on replacing the
condenser. Today's condensers have much
smaller tubes for better heat transfer. As a
result of the smaller tube size, it's nearly
impossible to flush out the debris entirely
from the condenser as it will become stuck
in the tubes.
The evaporator should be replaced
as well for the same reason, but in many
vehicles, it's not practical for the required
time. Make sure to thoroughly flush the
evaporator and the rest of the A/C system.
If enough of that debris stays in the
system, you will ultimately damage the
new compressor.
Many of our suppliers have begun
selling A/C kits that will include most
of the parts needed to repair the A/C
system properly after a major failure.
Don't forget to replace the orifice tube
as well when dealing with a compressor
failure. A good A/C job will also include
the replacement of the receiver/dryer or

accumulator anytime the system has been
opened to the air. There are desiccant bags
that will absorb moisture while the system
is open and will negatively affect system
performance if not replaced.
Like anything else, performing a proper
A/C system repair requires patience and
a thorough approach. Taking shortcuts
and skipping some of the suggested items
above can ultimately lead to a comeback,
more damaged components, and overheated
customers.
