I would hope so. The sniffer is the first step of any AC work. Find and fix the leak. Then work on the system. Sometimes the sniffer will find it and sometimes the leak is so slow or hidden in an area that is out of easy reach.
My ultimate test is vacuum the system then pressurize with dry nitrogen to 250 psi. Let that sit overnight and if it goes down, you still have a leak. Of course I don't work on any but my personal cars. And I am even slower that the shop you use. But my hourly rate is really high for cars I don't own. $1,000 per hour and I takes days to do an oil change. No one wants to pay my rate so I am happy.
