Art was as friendly and professional as could be. We asked for a quote for repairing our old AC unit, and after a thorough inspection Art let us know that the thing was D.O.A. (which we were already anticipating - the thing was ancient and breaking down pretty much constantly). So we requested a quote for replacement which he produced within 5 minutes. The quote was well within what I had expected through my internet research, and we scheduled him to return the following weekend (oh - and he works on the weekend!).
