Ahern is a 1,900-person mechanical and fire protection contractor built around HVAC, plumbing, sprinkler systems, and building controls. The tech stack is CAD-heavy (Revit, AutoCAD, Navisworks, Bluebeam) with field mobility (iPad/iPhone) and ERP-centric operations (SQL, Smartsheet), reflecting a project-driven, site-intensive business. Active hiring skews engineering and construction roles with accelerating velocity, while pain points around estimating backlogs, bid pricing, and ERP maintenance suggest operational friction as the company scales service and prefabrication work.
