Hey everyone, I don't post much but I have been watching for a while. I thoght maybe I could gain some insight. I did a leak check on a Ducane split yesterday and had a hard time recharging the system, just couldnt seem to clear the glass. I tried the usual by putting jug of 22 in bucket of hot water, and gave up after a few hours, and I guess I'm going to go back on a warm day to top charge off. Is there any tips or tricks you guys want to donate? Any advice would be greatly appreciated.
