The owner, Dave Tucker after owning a commercial HVAC company for many years decided a quality residential/commercial mechanical services company was needed. He had numerous requests to service additional clients at his high standards.

Dave opened Sigma Mechanical Services with the intent to offer a full service company that provided professionalism, trust and efficiency. Dave is a graduate of Boston College and a member of Alpha Sigma Nu the National Jesuit Honor Society.

The true meaning of Sigma is the sum of all professionalism, trust, efficiency, quality and reliability and that is what we strive for.
