Checked my AC out today being 83 degrees. It was about 1 can low. When driving I heard a hissing from the evap box area. This wasn't a vacuum leak either, it had spurting sounds. I think I may have a leak that I need to address. Hope it's not the evaporator but I can't imagine it being anything else. It's always been quiet in the past but maybe I didn't put enough freon in it and it's still low(pressures are fine and it's hitting the low pressure cutoff where it should be).

I may just run it up to work, suck the freon out with a machine and put it under vacuum to make sure I don't have any air in it and get the right amount in and see where I stand.
