I believe it's the air conditioning compressor that runs off the pulleys, Recently it started to make loud noises, not all the time, mainly when it starts up and is idling, Air-conditioning seems to work fine I was wondering if the compressor is going bad or if I need to lubricated or if there's another issue that you could help me with thank you

What kind of noise? If it's a grinding or knocking noise, it could be the compressor coming apart inside. If it's a squeal it is the serpentine belt slipping. Dribble a little water on the smooth backside of the belt while the noise is occurring. If the noise changes, look for a pulley that is out-of-alignment with the rest of them. That will cause the belt to slide sideways across it as it goes around it, and that will set up a horrendous squeal. As you sight down from on top, if the belt is peeking out on the side on one pulley by as little as 1/16", that is enough to cause a problem.
