my dad being hard headed don't seam to think you "need" to vacuum the system he being an old school guy that never went to school to be a mechanic just been doing it as a job for since i was a kid and but anyway think I'll sneak over to the shop and do it behind his back lol. what would cause the system to read full (low side in green about 40) only after adding once can of freon? you can head freon moving in the condenser but the low hose isn't cool anymore the high side is hot tho

I'm not following what you are saying  ???  Yes you do need to vacuum the system. Tell your dad since he's old school the old saying "do it right the first time" comes into play here.

They're better than nothing but if the system has been open you really want to use a vacuum pump. You know any HVAC guys?

OK vile its been a while but finally got the system working. After just dealing with the heat thought I suck up a little to the wife and fix the AC well took it to my uncle's shop and talked to him about my problem we start looking over it and my problem was the compressor would kick on and off very rapidly. So he hooked his gauge set up and saw my high side was way to high he said shouldest like a blockage. We looked over the system and told him everything is new except the evaporator. We talked about how the system works I learned allot the we talked about the orifice tube and how it works then I showed him were it was at and that it was facing the right way but then he questioned were it was at on the condenser. It was In The right spot but I had the hoses switched and had the discharge on the orifice tube and on the bottom. So took of home and did it right everything works nice and cool yet its only sitting at 30lbs but with the outside temp it should be about 50 so I might need to pick up a small bottle of freon. Thanks for your help on this vile

In the accumulator it would be the low pressure switch.
