Does this sound right?

I had a leak in my r22 unit. I called someone out to fix the problem, I paid a service call fee and he filled the AC unit with 4lbs on r22. He did a leak test with a meter and could not find anything. I was told I have a pin hole leak and by him filling up the r22, my AC should get me through the summer, and maybe a few summers. He did tell me about a nitrogen test, they could do, but they have to drain the system, they just filled. Do the test, then put an additional 6lbs in. I opted not to do the test. A week later my unit was completely empty. He came back out, did the test without asking me, put 200 lbs of nitrogen and it held for about 20 mins, he still couldn't find a leak. He put 6lbs of r22 back in the system along with a can of leak stopper, he wasn't sure if the stopper came all the way out. It didn't and I lost 2 more lbs of refrigerant about a week and a half later. He came back out a third time , put a different can of leak stopper and 2 more lbs of r22. I paid him the first time he was out (almost $400). Then I get a second bill months later for over $500. This doesn't seem right. If this leak was so small, why didnt he just put a good can of leak stopper the first time? Do I have a leg to stand on?

Pinhole I could drive my truck thru that pinhole.

Leak stopper is just about a complete waste of time. It gums everything up and doesn't stop the leak.

It sounds like the guy is just guessing at a repair. Did he have an electronic leak detector ?

I wouldn't have let him install leak stop.... it is known to cause systems to fail.... it is an absolute last ditch effort if a leak can not be repaired..... ALL LEAKS CAN BE FOUND through many different avenues.

MAKE SURE YOU DISCLOSE THAT YOUR SYSTEM HAS STOP LEAK IN IT! This is for the benefit for any additional tech who would hook his gauges up. If I know ahead of time I will NOT install my gauges as it can ruin gauges and with my digital gauges that would be really expensive let alone my analog gauges that are still around $100 (Most techs own their own gauges).

He did use a electronic leak detector, he couldn't find anything either time, the leak stopper did work. The AC has been running for a few months now. I just don't understand why the r22 would leak out so fast.

The first time he did not think the leak was that big, so he did not put stopper in there. Second time he knew the leak was big, so he put the stopper in. Anyway you are lucky for now at least, 80% the time, the leak stopper will cause problem down the road as mentioned.....
