A/C groans after a few minutes

I have a problem regarding the A/C in my 96 900S.
Over the weekend I rechared my A/C with a small can of R134 to a pressure of 33psi because I was under the impression that the A/C was not cool enough. Now the problem is that after switching the A/C on (nice cool air comes out) the system starts to give groaning noises after a few minutes running. It got progressively worse, so I switched it off. Noise goes away. Before recharging this noise did not appear. I did some reading here on the board, but it is not clear to me whether the recharging and the noises are related and second, whether it might be the expansion valve or the compressor that is shot.
Does anybody experienced something similar and does anybody have a recommendation for a repair shop in the Boston area? It is hot here!!!
Thanks so much
Markus
