what is the average low side pressure for yalls system. I got 100 psi and it blows pretty cool, but it the vacuum would not inhale all of the 2nd bottle of freon. thanks

 

100 psi is way to high on the low side, unless the compressor is not running. do you see it cycling on/off? should run about 20-35psi when the compressor is running. sure you don't have it hooked on the high side?
