A/C problems

What is your question?

I just charged the a/c in my Durango an the air did not come out an colder then before when they system was absolutely empty. After I charged it, it started blowing the refrigerant out of the top of then compressor where the lines come in almost like it was purging itself. But I didn't over fill the system. An the compressor clutch engages then dis engaged an non stop does it every 3 seconds
