Customer was getting new AC unit installed, installers found corroded pipes above old ductwork, removed/replaced and created leaks in t-joint above. I thought I had it all figured out; cut out top and bottom of t(to tub)unscrew t from lead to tub – new lead replace w/copper using adapters as needed. But, I couldn’t break any of the joints in the old pipe. I tried cheater pipe for more leverage, heat, hammer; constrained by not wanting to cause further problems down the line. Ended up cutting pipe and using Dressler couplings, not pretty, but works. What am I missing?

Few people understand it. Nobody agrees what it is, how to learn about it, or who's responsible for it. It has never been more important

Taking old galvy pipe apart can become an adventure in a hurry! I've used cheater pipes, but never got gutsy enough to start heating/hammering, etc. - lol
You mentioned "adaptors" and Dressler couplings. I'm not familiar with Dressler couplings, but I hope you used dielectric fittings where you transitioned between galvanized pipe and copper. Direct galvy to copper connections ain't a good plan. - lol
Actually, I never got to make a transition to copper. All ugly dressler couplings.
