I recently asked Airflow Service Company to come out and look at my fireplace. I was having some issues with it. Their people came out, and they showed up as scheduled. They were polite, friendly, and courteous. They were professional in their demeanor and work attributes. They did a good job of fixing the problem. The only reason why I am rating them at "Four Stars" instead of "Five Stars", is that I think it took them too long to fix the problem. A matter of timing. Their first crew came out and diagnosed the problem. Then, a second crew showed up later to perform the repair, but they apparently did not know what they were supposed to do. Finally, a third crew showed up and fixed the problem. I think that was simply a communication problem on their part, and they did end up accomplishing a professional repair. I just think they could have done it without having to send out three separate crews.
