I did for the most part, but I wanted to practice unbrazing so I removed the tubing coming off the suction and LL on my old compressor. I also bought some copper fittings to practice brazing with and attempted to unbraze those; they were 1" ID and were having none of that!
There was one street 90 that I wanted to re-use, so I did end up re-brazing that fitting to the air handler. I would have replaced it if I had a new fitting on hand but I did this on a saturday and hardware stores don't carry those fittings.
