Just for information sake!
I personally have mounted about 2000 split systems air conditioners. That is 8000 flaring joints. Very little (maybe 10-15) units have got leak problem in warranty period (2 years) and beyond. I know that because I servicing them regularly. I don't consider flared connection more problematic then brazed joints when they are maid correctly. Right tools and attention to details makes that happened.
A also have some 15 years old split systems with flare joints on which I never connected pressure gauges and they are working now as at first day.

Also, I think that they are not good solution where they are exposed to vibrations.
