Hey guys,

Thanks a lot for your help. It looks like everything was doing it's proper job since I discovered that I have absolutely no pressure in the system. When I got the system recharged the mechanics told me that they found only one tiny leak that only leaked when the system was on so I just figured that the system was still charged since I hadn't run it at all between the time when it was charged and a week later when I tried it again. And you know what they say about assumptions.

I haven't been able to find any leaks so I'll take it back to the mechanic and see if they can find any repairable leaks.

If they find out anything useful, I'll post it.

Thanks again,
Matt
