Hello Jermaine and thanks for requesting me to answer you question.
Well, without connecting pressure gauges to the system it is hard to say what is going with your A/C system, but we can check some basic things anyway.
You will need to feel ( touch feel) the A/C accumulator and low pressure lines connected to it when the engine is running and A/C compressor is ON.
If you system is properly charged and all refrigerant related components are OK, then the low pressure tubes and A/C accumulator must be really icy cold to touch.
If they are cold, but air coming out of the vents is not cold, then you have a problem with air distribution and it could be caused by a blend door ( air temp door) actuator.
If the a/c accumulator is not cold, but compressor is running, then it could be caused by number of reasons like: system undercharged, air passage across a/c condenser is blocked or engine fan is not working, a/c compressor internal failure etc. Without seeing low and high side pressure it is just guessing.
Please let me know about your findings.
