American Plumbing & Heating

What American Plumbing & Heating does

American Plumbing & Heating Corporation (dba AmerPlumb) is a privately held commercial mechanical contractor headquartered at 1000 Cordwainer Drive, Norwell, Massachusetts. Founded in 1994 and operating for over 30 years, the company designs, fabricates, and installs plumbing, fire protection, and HVAC systems for commercial construction projects across the Greater Boston market and broader New England region. Its customer base is concentrated in five primary verticals: education (Harvard, MIT, Boston University, Northeastern, Boston College), healthcare and hospitals (Massachusetts General, Brigham & Women's, Boston Children's, UMASS Medical), pharmaceutical and life sciences (Pfizer, Vertex Pharmaceuticals, Eli Lilly), sports and entertainment (TD Garden, Fenway Park, Gillette Stadium), and multi-unit residential.

The company's core technology stack centers on Building Information Modeling (BIM) integrated with Trimble software and a 43,000 square foot state-of-the-art prefabrication facility, enabling off-site fabrication of complex piping networks and just-in-time jobsite delivery. It also offers a formal Design Assist collaborative delivery service that brings plumbing expertise into the pre-construction phase, and supports LEED-certified green building work through LEED-accredited project managers. All plumbers assigned to medical piping work hold NFPA 99 Medical Gas certification, and all field supervisors are OSHA certified, supporting qualification for healthcare and institutional projects with stringent safety and quality requirements.

American Plumbing & Heating generates revenue primarily through project-based commercial construction contracts awarded by general contractors (e.g., Suffolk Construction), building owners (e.g., Hines), architects, and engineers. Revenue streams include one-time commercial plumbing installation projects, fire protection design and installation plus recurring inspection/testing/maintenance, and HVAC installation combined with preventive maintenance, repair, and 24-hour emergency service contracts. The firm pursues expansion through project-based reputation and direct B2B relationships in regional commercial construction, and in December 2025 announced an expansion of air conditioning services into Southwest Florida, marking its first documented geographic move beyond New England.
