I have a well maintained '03 Chevy Suburban Z71 which is no longer
producing cold, air conditioned air.  I haven't played with AC for many
years so any guidance will be greatly appreciated.
First, the compressor is running, the hose running from the compressor

I had Freon added to my AC and it drops 30degrees but it takes a long time
to get cold off. Do you think the Freon is leaking out or is there another
component that could cause this?
Thanks,
