AC system is holding vacuum. Just now getting back around to charging it. I'm going to charge it with propane and see if it holds. After the test, I have a whole case of R12. I'm debating if I should try to sell that to some boomer and buy the Frosty Cool 12a replacement refrigerant.
All my hoses are original and in good shape, except I'm suspect of the crimp on one hose. So I don't want to waste that precious boomer gas in case it goes.
Thoughts?
