Great, no problems. We called and initially left a message. He came the next day, on a Saturday, after his church function was over. We looked over the options that would allow us to do what we needed to within a certain budget, and he was very helpful in showing us the options. The price was very fair, especially comparing it to the first guy that came to do the same thing. By that Friday afternoon, everything was done, and other than the new units being in place and working great, you could not tell that anyone had ever been there. Very professional, very caring about his customers. No problem in referring to others!
