When it does work the one side of the line is very cold and the other is not so according to the book it should not need to be recharged. It seems that the compressor is kicking off and not comming back on. The previous owner had the same problem and took it in and they could find nothing wrong with it.

well thats all i can think of, i know someone that might be able to help(my HVAC instuctor) i will have to e-mail him, as soon as i get a reply from him i will let you know what he thinks.

he said it may be the pressure switch, or some temp. control thing (i forgot what he called it), but he said it is probably the pressure switch.
that would be caused by there not being enough pressure to hold it closed.
