The issue is the air is a non condensable in the AC system and as pointed out you really don't need a lot of it to cause issues as it circulates throughout the system. Automotive refrigerant systems are actually quite small volume so the air in unpurged lines is more than significant than you think. I don't have data to back it up, but even in the commercial and industrial systems I've been exposed to, which range in size from tens to hundreds of tons, you need to be mindful of purging your gauges before charging. Automotive AC systems are almost universally microchannel condensers which are particularly picky about charge and contaminants due to their more restrictive nature. As an aside, did any automotive AC come with a standard fin and tube condenser coil?
