I would rate my experience with Dean Mechanical as five out of five stars all around. I recently hired them to perform a service for the boiler and the work went very well. I have been using them for close to four or five years. They do regular maintenance for me and I have been quite satisfied with the final results. Based on my experience with the company, I would continue to use them in the future. In fact, I have already recommended them to other people. Thanks for all of the help!
