is my freon empty?? i just add one can 14 oz of freon, and another can of 12 oz freon. do i need more. i turned on the car, put the level to MAX, and at full blast. i left the car sitting there with the AC on for 3-5 minutes, and check the pressure. it was 25 PSI, after the 2nd can, it reads a little higher, around 28-30 psi. do i need to buy more cans of freons?? thanks guys

No, this is about the right pressure.

 

thanks a lot
