Our Story
When we began in 1989, our company consisted of a single vehicle and a single technician (who is still part of the Donnelly team).
Over the years, we have grown into one of the largest HVAC contractors—and the only integrated HVAC and energy company—in the New York City area, with over 130 employees and more than 90 service vehicles.
Corporate building owners, managers and tenants need HVAC and energy experts who are on the job today and prepared for tomorrow. As a result, more of them rely on Donnelly Mechanical. Our clients now include many of New York City’s most prominent corporations and institutions.
