I can't say enough wonderful things about my experience dealing with Bill Smart! He was prompt, professional, friendly, SUPER knowledgeable and VERY easy to talk with! He asked lots of questions in order to determine what my heating and cooling needs might be, explained every detail of the possible heating and cooling options I might have for my space, and thoroughly answered all of my questions. He even called me back after a few days to see if I had any MORE questions! On a 1-5 star rating scale, I'd give him TEN stars!
