Mainly a vacuum test is all that is needed
The pressure test would just be a final double check
Use freon if you are worried about air which I would not be
You are only going to be pressure testing for a few seconds
Use expensive as hell r1234yf if you are real worried about our atmosphere
Pretty sure they just use air to test with when remanufacturing AC compressors
