I was really happy with the work Sanders & Johnson did on our boiler, and I m really excited that we finally found an hvac contractor in Colorado that we can trust. I have hired a lot of other contractors that would brush off my questions, withhold any explanation of what they were doing, or would only answer my questions directly to my male partner, presumably assuming I couldn t understand the response anyway. Nick was extremely helpful in explaining how the system is designed to function and what was wrong. He was really knowledgeable and very quickly identified the problem, checked with me before he did any work, and got the unit back up and running properly in a short amount of time - after two other companies could not solve the problem after several hours. We look forward to working with S&J again!
