Why does the air conditioner stop cooling after driving for a long time?

I have a 2008 Chevy Aveo with 102,000 miles. The air conditioner will cool fine, and then, after driving for awhile, it will blow air but not very cool air. If I turn the air conditioner off for a little while and turn it back on, then it will blow cool air again. Also, condensation sometimes forms around the outside of the air conditioner vents. I was told that it needed a little freon so I had that replaced, but that didn't fix the problem.

Do you
have the same problem?

The cooling coil is freezing up due to the thermostat being adjusted to maximum coldness and there must be air leaks into the cabin.
