I will never, ever use these people again...been using their services for many years because I got tired of being ripped of by shysters All the people, especiallly their techs are superb. But beware of the so called "supervisors"----you will deal with arrogance of a third dimension and they (I should say "he" because I do not know the prick's name) are so above you and so defensive and for get that I was the one that paid $12,000.00 for a 3 ton unit, duct work and insulation. I will never deal with this company again because "HE" said that I offend him and to go elsewhere. Supervisors will NEVER , in their arrogance, ask what is the problem, what happened or give an explanation. Paid $700.00 for an electronic filter, and $143.00 for a box of 4 filters, and had even a second unit from them. The high priced one was the last. I am so sorry that I dealt with this company because of the "arrogant royalty" sitting in the front office . They sure forget who puts the scheckles in their pockets. And JATDUBYA1269----you got a good deal---I had my work done in January 2012. I guess the big shots needed a higher cost of living.
