We have replaced the A/C compressor 3 times in the last 3 months. on 2004 GMC Yukon

We have replaced the compressor 3 times and the clutch n pulley keep breaking??? I have a certified mechanic working on it and he is baffled. Help!!! we have blown out all the lines and such and it last a week or so then shells out.

Has he flushed everything, changed the orifice and expansion valve. Is the condenser clear or restricted? Is the pressure switch working. Just trying to get a little more info.
