I had my a/c serviced now the rear unit hissing.

(2000 Ford Expedition)
in Lake Worth, FL on November 15, 2012
I turned a/c unit on to defrost and a fine mist of freon came out of the air vents in the front.Within seconds i heard a hissing noise from the rear unit. Do I need to replacing everything in the rear of the truck? The system is blowing totally warm now.
