Complete Lifecycle Support for Industrial HVAC Systems

Hartwig Mechanical takes a full-scope approach to industrial HVAC work. We handle inspections, diagnostics, industrial HVAC maintenance, and replacement planning with the detail and foresight industrial clients expect. When a system needs to be upgraded or installed, we match the design to the demands of the process, not just the size of the building. We also conduct system performance reviews to identify inefficiencies and potential code issues before they become problems. All of this is performed by technicians who meet the safety and technical standards required for industrial environments.

We Build Safety Into Every Project

Working inside industrial facilities demands technical skill, awareness, compliance, and a culture of safety. Hartwig Mechanical ensures our crews are fully certified under NFPA 70e and NFPA 99 guidelines and trained for high-risk industrial work. We follow OSHA 10 and OSHA 30 protocols across all projects and ensure all welding and piping tasks meet B31.3 and other relevant standards. We’re prepared to protect your workforce, product, and our people while delivering high-quality work.

Industrial Ventilation and Air Quality Solutions
Whether you’re managing a manufacturing line or a food processing plant, your industrial ventilation system plays a critical role in air control, environmental safety, and compliance. We install, upgrade, and service ventilation systems that control contaminants, regulate airflow, and meet industry-specific requirements, all without interrupting your operation.
Long-Term Maintenance for HVAC System Performance
Our industrial HVAC maintenance programs keep systems running efficiently while avoiding unexpected failures. We offer routine checkups, filter changes, diagnostics, and performance testing tailored to your environment’s specific needs. Combined with our industrial property maintenance contract, we help facility managers keep everything operating smoothly and in compliance year-round.
