Hall's and them replaced my Goodman with a Bryant exactly a year ago. He was referred to me by another HVAC guy and the system has been functioning flawlessly. I just make sure I replace my filters like I should.
One thing that struck me about their install is how clean the work is. Everything from the neat wiring, to bend radius' on refrigerant lines and tape/mastic is very very clean. This is usually an indication of someone's proclivity to pay attention to small details that make a difference. Regardless of the system manufacturer, if it's not well installed it may not function properly and may not last as long. I am a home inspector so I am looking at others installs every day of every week and Hall's has the cleanest and best looking work of all that I see. And I see, in my experience, that it is very rare. I do recommend Hall's.
