An inquiry about A/C compressors failure

Postby lolo55 » Sat May 23, 2020 2:25 pm

I have a question. When A/C compressor fails, it often spreads dangerous metal particles through the system and this leads to a more expensive repair bill. I wonder if installing a filter right after the compressor to catch these solid particles would be a good idea. Making it possible to only replace the failed compressor without the need for replacing other compnents in the system. And does A/C circuits that use drier receiver are more reliable, since a drier receiver will catch solid contaminatns and prevent them from reaching and damaging the compressor.

It has been common practice for years in residential and commercial installations to install a filter just outside the compressor assembly on the high pressure line. I can only guess that the reason it never caught on in automotive is that there is no gain.

How there is no gain?. Auto A/C repairs are very costly only because when a compressor fails in a castrophic way it send metallic debris through the sytem. A filter will catch such contmaints and enable us to only replace the failed compressor rather than all A/C components.

Its all about the dollars. The manufacturer and the dealerships want you to return and pay for a more expensive repair. Planned obsolescence.

Maybe a non removable filter means having to either cut a line open or replace it, and a removable one means two more potential leak points...

Automotive A/C systems should not be compared to an HVAC system.

Filters will plug if enough debris is present. They make thimble system mess guards as well as this inline filter. Personally would never use either. But they sell them for people thinking it will somehow save their compressor. They also make refrigerant in a can with a charging hose. Not the best way to charge a system. But people are making money by selling them.
