5 INTRODUCTION TO FLUSHING WITH REFRIGERANT

5.1

What is Flushing?

Flushing with refrigerant is an action performed in order to remove solid contamination and old
compressor lubricant out from the A/C system. Using liquid refrigerant avoid the risk of
damaging internal components with aggressive detergents. In practice, once all refrigerant is
removed from the A/C system, most of the solid contamination is sticking to the lubricant
staying in the A/C circuits and component. Using refrigerant you will flush all the oil and the
loose solid contamination.
5.2

Why Flushing is important?

With respect to A/C system operation, component life expectancy and cooling performance, it's
of utmost importance to maintain a clean A/C system. Even the smallest particle of
contamination can cause restrictions and problems that will compromise the system.
According to A/C component manufacturers and rebuilders, flushing is important for warranty
purposes. In most cases if you do not flush the system, you will void warranty on the
components.
After a first component failure (i.e. compressor), you can assume that the system is most
likely contaminated. The replacement parts (rebuilt or new) will surely fail for the very same
reason, if the system is not cleaned out properly. Regardless of the failure that the A/C
system has experienced, when the system is flushed properly, it will be as clean (internally) as
it was from the factory and the full performance will be restored. Also the proper flow of
refrigerant and (more importantly) oil, will be restored, assuring long life from all the system.
