Do air conditioning units lose gas over time?

I have been told by a dealer that air condition systems loose 10 per cent of their gas every year, is this correct?

It's an approximation, but yes. The gas gradually seeps out of the seals in the system; more so during the winter if the a/c is not used because the lubricants are suspended in the refrigerant and if this is not regularly pumped through the system the seals dry out.

I had my air-conditioning regased but when I went to put it on again the next summer it wasn't working and the same garage said it needed regassing again. They also said I should keep my air-conditioning...
Is it true that you should have your recirculation button on all the time in summer when you are running the air conditioning?
How often should the aircon be serviced on my car?
