Customer Testimonial

"Diamond Mechanical, Inc. has been the primary HVAC and Mechanical contractor for the Boston Marriott Newton for over two years. Major projects during this time include the replacement of the domestic hot water production and distribution system; replacement of a 300 ton Carrier chiller; and significant advancements in our building control system. Many smaller but no less complex projects have been completed by Diamond, including recommissioning air handlers, rebuilding plate and frame heat exchangers, as well as significant preventative maintenance. 

We have experienced a high degree of value with our relationship with Diamond Mechanical. Mr. Brian Gerrior has demonstrated significant dedication to ensure our satisfaction. On many occasions, Brian or a member of his team has gone over and above to ensure that our operation continues uninterrupted. 

In my experience, business confidence and trust with a strong ethical backbone are a rare find in business. I have found that in Diamond Mechanical."
