I have a son in the business. The new AC machines can evacuate and recharge a system without the compressor running. They record what they evacuate and the difference between that and the recharge would tell you how low the system was. Full recharge info is usually printed near the ports.
However, to verify all this you need high and low pressure readings which require a running compressor. It seems odd that a company would do all this though in a system that has a compressor that doesn’t work.
Well, I also am IN THE BUSINESS. 43 years worth. I guess I did not make it clear, but the recovery system does NOT need the compressor at all. And not all AC shops have the very expensive recovery systems that would state exactly how much was recovered. We don't. Not needed. Also, is your son in the RV business or Automotive business side. BIG difference. Doug
