I have been working with Christen Brothers Service for about ten years, now, and have been, for the most part, entirely pleased. They've done all sorts of work for me, and it's all gone very well. They're easy to schedule, and I never have any trouble with them canceling or being late or any such thing. The only thing about them that's ever been not perfect is their window repairs-- I feel like, when I get a window repaired, it doesn't tend to last, and has to be re-repaired a year or two later. Otherwise they're great, though, and I'd be sure to recommend them!
