The office staff and the guys who did the installation were all very helpful and knowledgeable. I had an old system that was costing me a fortune on my electric bill and the salesperson, who was also the president of the company, showed me what it would cost to put in a new one. My electric bill was way lower than May of last year and it is so much more quiet. I did get another estimate and it was nearly $200 less but I felt a lot more comfortable with an established factory authorized company. I hope I don't need anything else for a while but if I do Im calling them again. A++++
