First you need to check if the compressor is actually kicking in when started and you can do that by looking at it and you will see if it is working or not. If not working you ned to check the folowing : 1- AC compressor is getting electric , if not check the relay for the AS compressor. 2- Check if the AC compressor's clutch is kicking in (that is the part that is located on the front of the compressor , where the belt is fitted) 3- Check the compression of the AC compressor via a proffessional.
