Hi,
My air con no longer provides cool air. It just omits, standard outside air. Prior to this I heard some hissing noises near the centre vents.
Does this mean my car needs re-gassing?
It is 5yrs old with 102,000 miles.

thanks

The hissing was probably the gas expanding, there are many reasons for no cold air, compressor, sensors,and pressure switches. try this site for diagnostic info
