Annexair Tech Stack

Energy-recovery HVAC systems for commercial, institutional, and industrial buildings

Mechanical Or Industrial Engineering St-Germain-de-Grantham, Quebec 201–500 employees Founded 1998 Self-Owned

Annexair manufactures air-handling units and energy-recovery systems for North American commercial and industrial clients. The tech stack—AutoCAD, Solidworks, CATIA, C#/.NET, SQL Server—reflects a traditional manufacturing-software hybrid: heavy CAD for product design, custom .NET applications for internal tooling, and basic ERP (Dynamics NAV/Business Central) for operations. Active projects include units for NASA, Google, Harvard, and Coca-Cola, plus a lightweight web-based HVAC component selection tool. The hiring acceleration (6 roles in 30 days across engineering, ops, and manufacturing) paired with documented pain points in procurement logistics, supplier rationalization, and ERP data quality suggests scaling production while wrestling with supply-chain complexity.
