Default How long before you AC's freon ran out?

Mine just ran out recently after 7 years. Is that about right?

Mechanics couldn't find a leak anywhere so I guess my 99 RS just ran out.

I just had the 99 Legacy recharged. There was a slow leak in the pipe between the drier and compressor. New 0-ring and all is good.
A friend of mine just recharged his 1983 Porche 924. No leaks works great.

The AC is a closed system. Freon doesn't get used up. if it runs out, it is leaking.

Were the mechanics using an electronic leak detector? It's hard to detect small leaks without one.

Yeah, they were. I don't know much about the AC system. Believe it or not, this is the first car I ever owned that needed the AC to be recharged.

Cool

Technically the AC is not a closed system because of the compressor i.e. the shaft seal. My 2000 Forester w 108,000 miles still puts out cold air at ~ 37 degrees below ambient temp which is within specs. Florida car that runs AC about 9-10 months a year.

I had mine charged in the spring on my 2000 RS with 120k. It stopped blowing cold air mid-last summer.
