The pressures cannot tell you how much refrigerant you have in the system. The only way you can know is by completely evacuating the system and recharging with the exact weight required. Everybody thinks AC is simple to diagnose and it couldn't be further from the truth.

Re: air not working

If you put a vacuum on the system, and you couldn't get refrigerant to go into the system, either you didn't pull a vacuum on the system or you have faulty equipment. If you didn't pull vacuum, you have air and refrigerant mixed in the system now. I suggest you take it to a shop that has the proper equipment to charge it up for you. As HT stated AC systems are charged by refrigerant weight and not pressures.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Re: air not working

amoscradersr : You mentioned "cans" so that and calling it "freon" means you shouldn't be touching this without some help and you are here so that's what I suggest - get help,
