Not that I know of. I hear that pag oil will short out a hermetic compressor though.

Thanks for your reply @R600a.

Yeah, that would make sense since PAG oils are conductive.

I was wondering if an evap designed with PAG oil in mind might clog up more with POE oil.

 

The reason for pag as I understand it, is that it doesn't go to acid if moisture is in the system like poe does.
And if you've ever done automotive ac on a flat rate system, you'll understand that those systems NEVER get a proper vacuum

 

I photograph all my equipment including the model number and serial number and iD etch certain information underneath like my phone number and initials where no one would look typically…

Of course I have had a few stolen items over the years and got 98% back because I had that metal etched marker…but not my $650.00 large Bosch chipper/demo/rotary hammer ….
I still randomly look for it and it was over 7 years ago, lol…I have never left behind another expensive tool on a job site in a “locked contractor area” tool room that was also in a locked job box…..

 

Same here. We never leave the more expensive stuff anywhere on the job site. We have cheap pencil engravers to make sure things don't get "mixed" up. Metal or plastic, it gets engraved. We also keep a record of serial numbers.
