The Tustin Group

What The Tustin Group does

The Tustin Group is a privately held, integrated building services company founded in 1992 and headquartered in Norristown, Pennsylvania. It delivers mechanical (HVAC/R), energy management, water treatment, fire and life safety, and plumbing services to commercial, industrial, and institutional facility owners and managers across the Mid-Atlantic region, operating from eight physical branch locations spanning Pennsylvania, New Jersey, Maryland, and Virginia, with service territory extending to Delaware and Washington DC.

The company's service model combines recurring preventive maintenance and service agreements with project-based design, installation, and 24/7 emergency response work. Technical capabilities rest on building automation systems, web-based energy management platforms, water sampling and treatment data collection (as an authorized ChemTreat dealer), high-resolution camera inspection technology for plumbing diagnostics, and NICET-certified fire protection personnel for NFPA 25 sprinkler inspections. The integrated single-vendor model differentiates Tustin from point-solution competitors by offering facility owners a single point of accountability across multiple building systems. Tustin supplements the core service portfolio with a US Department of Labor-accredited HVAC apprenticeship program and a ProVet partnership supporting veteran workforce transitions.

The go-to-market is direct field sales through branch-based service teams and technicians, with revenue derived primarily from multi-year service agreements and maintenance contracts, complemented by design-build, installation, and emergency response projects. The company has grown organically and through acquisition, most notably the November 2020 acquisition of Delattre Corporation, which expanded operations into the Pittsburgh market and added in-house custom ductwork manufacturing. The Tustin Group employs more than 300 people and is recognized regionally, including as a 2022 Best Places to Work honoree by The Philadelphia Inquirer.
