A.C. Doesn't feel like it is cooling for approximately 10 miles. on 2006 Volkswagen Jetta

I have a 2006 GLI. Just bought it this January. A.C. blows extremely hot air for several miles. Takes about 10 miles before I can even tell the A.C. is doing anything. The temperature is over 90 outside and the car sits outside during the day. I check the freon and it is full. Does anyone have any ideas.
