System Flushing

System flushing

This is usually required as a result of a failed Air Conditioning Compressor. If the compressor suffers wear or a complete internal failure, it is likely to pump metal particles (swarf) around the entire system, and will eventually block the refrigerant flow or may lead to failure of any replacement parts fitted.

The flushing procedure involves disconnecting the system joints and using compressed oxygen free nitrogen (OFN) to pump a special flushing fluid through each pipe and component of the system. When this has been completed, the system can then be repaired and tested.

Note: If the system does require flushing, we would recommend a new Receiver/Dryer, Parallel flow Condenser and Thermal Expansion Valve are fitted, as these components cannot be cleaned effectively by flushing.
