Exclamation Need new unit or maybe another HVAC specialist?

Is it possible to overfill a home ac unit with freon and cause a leak in the pipes connecting to the compressor?

Also is it possible that a previous compressor burnt out and when a new one was put in the pipes werent flushed before hand so now the pipes are ruined and therefor continue to create a new leak (after you've welded any existing leaks) everytime you activate the unit?

I'm having a problem with my AC unit, guy was out here today and found out I was out of freon so filled it with 8lbs, which is what he said my unit holds (unit is from 94, compressor is from 2003 based on panel attached to unit and looking at the compressor), and when we started it we could hear the leak immediately. Thankfully the leak was on the pipe connecting to the compressor right where a pipe meets another pipe. So he welded it and filled it back up and took off. Shortly after the unit stopped running and he came back out, filled it and found another 2 leaks near the one he welded previously. He welded them and we added freon and about 5 minutes later it popped again and it was leaking again.
I believe he either overfilled it causing these leaks or what he said, the previous burnout has cause weakness in the pipes and they will just keep bursting open.

I really wanted AC today as it is over 100 degrees everyday right now in Kansas and I'm staying alive with a small unit in my living room, I need to come to a conclusion about whether I should just replace the whole unit or get a second opinion first and have someone else come out and spend more money....

I would appreciate some opinions on this matter. Thank you!

I do not think that he over filled the system and caused a leak.

Your piping may be severly corroded and he may have failed to properly sand it before brazing it. Was the leak in a location that is difficult to access?

If it is a 1994 system a new one would be best but I wouldn't call that tech again. Was it flat? Did he replace the drier and pull a vacuum?
