Hiss From Behind Dash After Engaging A/C

Hiss From Behind Dash After Engaging A/C
Hello,
Just wondering if anyone has or has had this issue, or if it's perfectly normal and not an issue at all.
If I'm driving around with the A/C off (ECON mode) or with the fans off (system off), and I turn on the A/C, just as soon as the compressor engages, I'll get a 2-3 second hiss from behind the dash, probably the evaporator.
As the compressor cycles on and off, each time it engages, I'll get the hiss again.
Just wondering if I need to look into it. During the summer, it ran Okay, but I'm thinking maybe I have a low refrigerant condition. I'd have to put the gauges on it to see for sure...
Thanks,
Nick

Nick:
I had the same 'problem' a few years back. Car sounded like Darth Vader after a while. I had it recharged and the hiss went away. Problem is, that refrigerant is really hard and expensive to come by in my area, so I need to have the retrofit done. I was thinking about doing that this summer. Don't know if you'll have the same problem, or if your system has already been converted.
