    You need to know subcool and superheat. Your subcool should be higher than 3. Sounds undercharged. What was the superheat?

    only half of coil getting cold? 3 degree SC? not sure what spilt is... If its milk, you aint supposed to cry. I know that. I've heard old timers call the temp difference the "split". If thats what you're talking bout, 10 just wont do. I'm probably wrong but I'm thinking under charged.

    get your subcooling up to 10 and see what happens.

    It sounds like you're undercharged.

    Are you saying you ran the ac with no blower? This would sure cause all your tubes to freeze.
    You need to put the phone down and get back to work!
