What Tappouni Mechanical Services, Inc. does

Tappouni Mechanical Services, Inc. (TMSI) is a privately held, family-owned commercial mechanical contracting firm headquartered in Tampa, Florida, founded in 1981 by Mike Tappouni, a 1961 University of Florida College of Engineering graduate. The company designs, installs, and services commercial HVAC/R mechanical systems with a stated specialty in chilled-water and condenser-water systems, and maintains capabilities across heating and hot water, steam, sheet metal ductwork, underground piping, and plumbing. Service offerings run the full project lifecycle, including pre-construction consulting, design-build delivery, energy efficiency and sustainability work (geothermal, energy recovery, LEED/Florida Green Building/Green Globes/WELL certification support), startup/commissioning, and ongoing service and maintenance beyond warranty. A marquee technical accomplishment is the state-of-the-art heat pipe refrigeration system installed at Amalie Arena for the Tampa Bay Lightning, providing NHL-grade ice conditions.

The firm generates revenue primarily through fixed-price, project-based contracts for commercial mechanical system installation, supplemented by service and maintenance agreements. Projects are delivered through two principal channels: direct engagement with institutional owners (universities, hospitals, government facilities, museums, religious organizations, and other commercial property owners) and subcontracted work under preferred-vendor relationships with tier-one general contractors including Skanska, JE Dunn Construction, DPR Construction, A.D. Morgan Corporation, Ajax Building Company, and Batson-Cook. Customer mix spans commercial and industrial, educational, healthcare, and government/institutional verticals, with named anchor projects at Florida Polytechnic University, Johns Hopkins All Children's Hospital, Tampa International Airport, the Tampa Museum of Art, and the Tampa Bay History Center.

Leadership transitioned from founder Mike Tappouni to his daughter Michelle Tappouni as President; she brought 35+ years of construction and real estate experience. The business operates as a single-jurisdiction entity in Florida with its operating geography limited to Tampa Bay and the state of Florida, no parent company or subsidiaries, no funding rounds, and no disclosed revenue or headcount figures. The company is privately held and ipo_status: private.
