After a catastrophic compressor failure, it is extremely important to eliminate and/or contain the debris from the compressor that may have circulated through the A/C system. The debris generated from a catastrophic compressor failure will be discharged into the compressor suction line, discharge line, condenser and liquid line and may cause the new compressor to fail prematurely. In addition to flushing, a liquid line filter should be installed in the system to stop any remaining debris from circulating through the system.
Most refrigerant recovery/recycling stations have the ability to flush the system with cleaned and dry refrigerant. Keep in mind that the refrigerant oil in the system will also be removed and must be replaced when refrigerant is added to the system. Follow the instructions that came with the equipment to properly flush the A/C system.
