no a/c

I have a 2000 intrepid which i really love, the only problem i have is that when i turn the a/c on it does not get cold, have refilled freon only lasts about 2 weeks, cleaned fans...any ideas?

I... have refilled freon only lasts about 2 weeks
DIdn't they check for leaks before refilling ? THis seems to be the most probable cause....But is New Jersey that warm at this time of the year?...suggest you wait for spring..unless you have other weird symptoms

is there any weird chemical smell from you vents when you first turn the ac on
