A few qualifications about my experience with AC on my GTI and on my R
Neither car had good climate control - set at a temperature, the climate control would always over cool requiring constant adjustment. (Plenty of posts on many forums lists the same)
The gradient between temperatures, for example 18 and 24 wasn't that good. On very hot days, worse.
So called "hissing" if its the sound I'm thinking of, was on both my cars from new and still is on the R. It's normal AFAIK.
By all means get it checked but the VW system has its quirks.
