Verde Sol-Air Services did a gradient heating and solar heating consultation for us. It went fantastic! Richard was the person who helped us out with the consultation process, and his service was top-of-the-line. I was especially impressed by his expertise, his confidence, and his ability to get to the bottom of the problem. After speaking with Richard in the initial consultation, we have decided to go ahead with the rest of the entire project. This was the first time we tried using Verde Sol-Air Services, and after such a great experience, of course we would go back again for any similar services. I would always pass on a good review of them; they are a top-of-the-line outfit!
