Hot Water Boiler

Technician

Technician is a widely recognized professional role in HVAC engineering, explicitly referenced in ASHRAE guidance for cooling tower systems. While generic, it denotes a credentialed, hands-on technical role responsible for installation, commissioning, operation, inspection, maintenance, troubleshooting, and testing of HVAC equipment including cooling towers. It is not product-specific (e.g., no 'Cooling Tower Technician' prefix), so product_specific_title = false. The role is distinct from engineers or operators and falls under the Maintenance family with broad technical execution responsibilities.

Mechanical Engineer

Facilities Mechanical Engineer is a widely recognized professional role in building services and HVAC engineering, focused on the design, operation, maintenance, and optimization of mechanical systems—including chillers—in commercial and industrial facilities. While 'Facilities' denotes a domain specialization (not product-specific), it does not make the title product-specific (e.g., not 'Chiller Mechanical Engineer'). The role is distinct from generic Mechanical Engineer due to its consistent association with facility infrastructure, lifecycle management, and integrated HVAC system oversight. Evidence from job boards (Indeed) confirms real-world usage with explicit chiller-related responsibilities.
