As a 35 year veteran within the commercial building industry, I’ve had the pleasure of working with Donnelly Mechanical on many projects, both large and small, throughout the past 30 years. One of the more recent projects I’ve worked on with them was the first phase of an ongoing HVAC unit retrofit. The project, although extremely complex, was a great success. We received the professional experience I’ve come to expect from the Donnelly team. Their support, communication, and ability to finish the job properly and on time is second to none. From the executive team to project management and technical support, the entire Donnelly team offers a personal support system and prompt reply to any and all requests during every phase of a project – a level of service that is hard to find in the industry today.
