Mike Williamson

With over 40 years of experience in the HVAC industry, Mike Williamson is the definitive authority behind ITDG's mechanical operation — and the qualifying party for the company's HVAC license. That credential isn't just a formality; it represents four decades of mastery in the layout, design, fabrication, and installation of HVAC systems built to exacting project specifications.

Mike possesses extensive expertise in sheet metal fabrication — a capability that most general contractors subcontract out entirely. At ITDG, Mike's team fabricates and installs in-house, giving the company direct quality control over one of the most critical comfort and performance systems in any building.

The result is tighter tolerances, faster turnaround, and zero dependency on outside vendors for critical-path mechanical work. As HVAC Division Manager, Mike is responsible for the full scope of the mechanical department: system design, cost estimation, and supervision of field operations.

He ensures efficiency and quality throughout every phase of every project — from initial engineering through final commissioning and balancing. Mike's ability to design systems that perform optimally while staying within budget is a major reason ITDG's vertically integrated model delivers such significant MEP savings.

When the electrical and plumbing divisions are coordinating with an HVAC team led by someone with 40 years of expertise, the result is seamless integration that subcontracted crews simply cannot match.
