I have never had central air and was very confused as to what to get. I looked at homestars listings and found my soluction which was this company and talking to Dennis just put me at ease. He answered all my questions and even when I called he was patient and eager to make sure I understood. I had called so many companies and they were just trying to sell. But Denis was very interested in customer satisfaction. The installation was great and now I am so COOL!!!! I recommend Dennis to all!!!! Thanks so much Dennis
