Pressure building up on air conditioner of my 1996 Chrysler LHS

What is your question?

Hello, I have a 1996 Chrysler LHS, and it is having air conditioning issues. My mechanic put a new condenser in, the cold air was working great for about 15 minutes and then all of a sudden it started squealing and smoking and the new condensers clutch broke. This is the second condenser that was put in with the same result. What is building up the pressure to cause this? I really appreciate your insight on this, if you know. Thank you, Julia
