My POA valve / suctioning valve freezes up when I add free-on?

    Hi, I have a 67 Skylark. When I add free-on to my air conditioning system, the valve freezes. I'm just wondering if that's normal? Thanks!

    sounds like non condensibles i would change the receiver dryer ,flush the system at least the condenser, and vacuum it for at least 30 minutes then recharge

    Does it cool when your not adding Freon? If your charging at the port near the POA your dumping liquid refrigerant into the system. it will "flash" as soon as it hits the valve and be super cold therefore making it look as if its freezing up. I'd charge to specs and see how the system performs
