Started by a contractor. Built for contractors

Gannon Mechanical Group was founded after years as a mechanical contractor working with engineering that looked good on paper but fell apart in the field. Drawings that didn’t account for real-world conditions. Load calculations done with rules of thumb instead of actual math. Reports that couldn’t survive an inspectors questions.

We built this company to fix that. Every calculation we produce is done with ACCA-approved methodology. Every design package is built to be installed, not just submitted. We stay engaged throughout construction because we know the job isn’t done just because the drawings are.

We work with mechanical contractors – no architects, no developers. That focus means we understand your projects, your schedules, your submittals, and what it takes to get the job done right.
