A/C Compressor/Pressure Switch Help VE V6 Series 1

[shane_3800]

When gas leaks out of the aircon sealed system, through a faulty hose for example, it takes oil with it. The amount of oil actually lost this way can’t really be measured. So it‘s either ignored or a loss amount is guessed based on some generic industry guesperiance. Problem is the system may be under filed overfilled as a result.

The correct process would be to spend the time and money to flush all existing oil and clean the system and ensure the new compressor has the full amount when installed. Then the system should be flushed with dry nitrogen and pressure tested before being evacuated and vacuumed tested. Only them should refrigerant be added. Oddly when you try and talk to the aircon guys about the process they use,, they are dismissive and don’t explain why some things aren’t being done by the book. may be the experts want to have some excuse up their sleeve why things still failed after doing their cut price regas... oh, you should have done b, c & d but I tried to keep it cheap for you...

Sometimes I think some aircon guys are professional clowns. (If I hear one more time from a professional that the filter doesn’t need to be checked and desiccant bag doesn’t need to be replaced or the system doesn’t have these components (any more), I’ll crack it with them.)

There are some out there that shouldn't have their licence. Then there are people like the guy I work with that cracks the shits when we pull a front end off a car and then regas without doing a reciver dryer.

Another issue is auto machines as they recycle gas but you never know if there's water or LPG or even air in the system.

All these issues is why R134A is being phased out for environmentally friendly gasses which under perform compared to R134A.
So when A/C is warmer and more expensive to fix blame it on all the DIY guys and dodgy mechanics out there.

unfortunately time is money, professionals are meant to do the proper job but at the end of the day customers will only pay so much for labour time and the job in total, especially when the cars aren't worth anything once the aircon is dying, so it's never done properly. Hence why so many things are DIY these days. But the laws are put in place to stop education and DIY. License's print money to. Anyway hopefully the OP has his question fully answered.

Hahaha, a business owner blaming a customer because the business owner broke environmental laws and the conditions of his license. That’s typical of a lack of business ethics and lack of any self responsibility as shown by such business owner where their logic is to make money at any cost...

Such behaviour (environmental vandalism) should never be acceptable...

unfortunately a lot of shops run like that.
