This is the WORST HVAC company ever! My 17 month ordeal / installation story is too long for me type out. What ever you do, DO NOT purchase any services or products from this company. Their techs are incompetent, their management is non-existant (& equally incompetent), and their prices are higher than others. I knew their price was higher, but I thought I was getting professional and quality installers and service techs...I got neither. They come to fix one problem and cause another. They can never order the correct parts and constantly rescheduling me. In particular, stay away from the Fairfax office. Todd Kirby was our sales guy that sold us our system. He promised things they can't deliver and months after our installation and issues, they promoted him! He is now the manager of the Fairfax office, and this scenario has gone from bad to worse. YOU HAVE BEEN WARNED
