Forgot to add, I know about the R-22 spraying all over, that's what happened with my last window unit. Granted it was the second time I was trying to bend the coil out and unbend a U after already unbending and rebending it once. The odd thing was that it didn't come out at that high of pressure or even get cold when it leaked out. It was like compressed air was escaping. So now I have an empty window unit sitting in my shed. Too bad I don't have the equipment to fix it.
Has anyone ever tried the purging method of charging? where you just feed the refer in at one point and go until its pushed the air out of the system, then charged? I know this is bad practice and probably asking for trouble, but some of those chinese minisplits tell you to charge them this way and they run fine, for a while anyway. This wouldn't be my primary machine, just a, well it's already broke so why not, experiment
