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?

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.
