Visteon A/C Tech Bulletin: Prevent Repeat Compressor Problems by Performing a Complete Repair

Automotive service shops often can avoid repeat repairs of air conditioning (A/C) compressors by replacing the compressor, condenser and other affected parts during the initial service occasion, according to Visteon Corporation, a manufacturer of original equipment-quality replacement A/C components.

Visteon recommends that service providers replace the compressor, condenser, accumulator/receiver drier, expansion device (thermo-expansion valve or orifice tube) and any system hoses containing mufflers in cases where the compressor has seized due to a lack of lubrication. Although the condenser and other components might not initially appear to have been damaged, compressor-related debris is likely to cause a plugged condenser and other issues.

“A growing number of A/C technicians have discovered that simply flushing the system often won’t remove all of the debris from the system. Most condensers contain a tube size and shape that make them virtually impossible to flush thoroughly,” said Reno Farrugia, climate product manager, Visteon. “The best value for the shop and consumer in these situations is to replace all components potentially impacted by the compressor’s failure.”

In cases where the compressor issue has not contaminated the A/C system – as when a leaking seal causes refrigerant loss – replacement of the compressor alone will likely suffice, according to Farrugia. “In those cases, you don’t have to worry about particulate matter being circulated through other system components,” Farrugia said. “The ultimate objective in every A/C repair is to ensure there is no contamination of the system. Unfortunately, we see cases of repeat repairs that could have been avoided by replacing all of the components affected by the initial failure of the compressor.”

Visteon recommends that shops rely on visual aids such as component cutaways and system diagrams to explain to the vehicle owner the need for multiple parts replacement. “Obviously, the consumer would rather replace only the compressor, but they’re far more likely to authorize the complete repair if they understand how the initial problem has effected the condenser and other system components,” he said. “The last thing anybody wants is to have to pay for a job twice, so explaining these facts becomes a real source of value for the customer.”
