I've been using Airflow since I bought my condo in May 2008. I had to replace my hot water heater and furnace, and they not only made sure I knew all of my options, there was no pressure whatsoever to take the most expensive one. It really felt like it was all about me and my needs, and not about selling something for a lot of money. They did a perfect job of installing the equipment and have been incredibly responsive and friendly any time I've needed any work done.
