"This business is excellent. We received three quotes from various businesses and D&M was the only reasonable one. The installation was done in a timely manner. The owner did an exceptional job and was both professional and efficient. Based on his service, we have decided that from now on, all service for all boiler will be done by this organization. You cannot go wrong with D&M. I highly recommend him!"

"It exceeded my expectations. The initial consultation really assured me that I was getting exactly what I needed and nothing more. The installers were very knowledgeable. I was also very impressed with how well they explained the preventative maintenance agreement on the unit. It gave me peace of mind, which is priceless in terms of the value of the job. Overall it was a great experience."
