Out of curiousity, exactly how do you test for leaks without charging the system? I know making sure the system holds a vacuum is part of it, however the 14.7psi pressure difference between a vacuum and atmospheric is alot easier to hold than the 115 psi (minimum, it will likly be alot higher) pressure difference that will be between the high side of the system and atmospheric. So a system that holds a vacuum could still leak in use. I'd really like to know the answer to this because i'll have to cross this bridge sometime myself and any trick to let me test for leaks without wasting freon will be greatly appreciated. Especially since I plan to use R12.
