The Story of SIGMA After owning a commercial HVAC Install Company for many years David Tucker opened SIGMA Mechanical Services to fulfill a need in the South Shore community with a professional and trustworthy HVAC company. He went out to every job, made every sale, and when he was too busy to do every job he still came by to make sure everything was just right. One of the reasons SIGMA has been so successful for the past 7 years is by staying dedicated to our core values as a company. David Tucker is a graduate of Boston College and a member of Alpha Sigma Nu the National Jesuit Honor Society. He currently lives in Marshfield, MA with his family. The true meaning of Sigma is the sum of all professionalism, trust, efficiency, quality and reliability and that is what we strive for.
