strange leak

every time I top-up, my a/c refrigerant leaks down only to a certian level in a few days.

is there some kind of faulty control valve that releases the freon gas to air assuming it was overcharged??

please help

If you have the proper fill and it leaks down you have a leak.

You will have to do a leak test. I use a ultrasonic detector to find leaks.

Find and fix the leak.
