I have been having problems with my AC being cold at times and then warmer. I have noticed a couple of times that there is a fog like smoke coming through the vents. Freon was added a couple of weeks ago and the levels were checked again and are still good. The vacuum line was check and the vents checked out fine.

The AC system could be freezing due to air and moisture forming ice blocking off the orifice that needs to be vacuum out or the freon is still low

You sure its not leaking?
