Why is my A/C not blowing properly. A/C is in there and everything else works.

A/C systems are very complex and requires the proper refrigerant. I often see A/C systems overcharged, undercharged or even systems that have air and moisture in them. If your system has air in it then it will have to be vacuumed out for about 30 minutes to remove the air. Air is a non condensable gas and moisture in the system can form ice crystals and become a restriction for the refrigerant to flow properly. Once the system is filled with 100 % refrigerant and you have a low side and a high side reading only then can someone diagnosis it properly.. Until these three things are done then one can only take a guess what the problem is. Best of luck Chuck
