HVAC MECHANIC II
Arlington Public SchoolsAbout the role
Human Resources announces an opening for a 1.0 FTE position as HVAC Mechanic II with the Facilities and Operations Division, School Support. This is a twelve-month, , Grade M-15 position.
GENERAL STATEMENT OF DUTIES
The HVAC Mechanic II is responsible for ensuring the safe, reliable, and efficient operation of heating, ventilation, and air-conditioning (HVAC) equipment throughout Arlington Public Schools (APS) facilities by completing full-performance, journey-level installation, operation, adjustment, maintenance, and repair tasks. The employee troubleshoots components and subsystems, performs routine and moderately complex maintenance, and applies standard trade practices to resolve equipment issues accurately and efficiently. The mechanic uses diagnostic tools, interprets basic schematics, and carries out repairs in accordance with industry standards. The position also supports senior-level technicians by assisting with more advanced repairs and diagnostics on commercial, industrial, and residential HVAC systems, while performing digital controls programming, BAS/EMS reprogramming, complex refrigeration repairs, and/or system-wide performance analyses. The incumbent ensures the consistent delivery of comfortable, safe, and properly conditioned learning and working environments across APS buildings. Accurate performance of duties helps maintain system reliability, reduce equipment downtime, extend asset life, and ensure compliance with safety and environmental requirements. The incumbent supports school staff, students, and facility operations by maintaining stable building conditions and promptly addressing HVAC-related concerns, while establishing uninterrupted instruction, operational continuity, and effective facility management.
SUPERVISION
The HVAC Mechanic II reports to the HVAC Maintenance Supervisor or Assistant Supervisor, receiving assignments through work orders, schedules, and service calls that typically specify the objectives, priorities, and deadlines of the task. Once assignments are received, the employee is responsible for planning and carrying out recurring and routine journey-level HVAC tasks independently, applying established trade practices and accepted procedures to diagnose and resolve component-level issues. The incumbent exercises keen judgment to determine when unfamiliar, atypical, or system-level conditions that require referral to the HVAC Mechanic III or the supervisor. As a level II professional, the employee may provide basic guidance to temporary workers or HVAC Mechanic I personnel in the course of daily work. Review of work is generally limited to periodic checks for technical adequacy, completion of assignments, compliance with procedures, and overall customer satisfaction, reflecting both the employee’s independence in performing standard work and the requirement to seek supervisory direction when assignments exceed journey-level responsibility.
DISTINGUISHING CHARACTERISTICS
The HVAC Mechanic II is a journey-level classification in the HVAC series, where assignments involve a full range of standard HVAC tasks that require the employee to apply established trade methods, interpret straightforward technical information, and resolve routine or moderately complex equipment issues in conditions that are typically clear-cut and familiar. In carrying out these assignments, the HVAC Mechanic II considers known procedures, manufacturer guidance, and standard diagnostic steps to determine what must be done, exercising judgment to identify component-level problems while referring atypical, unclear, or system-wide issues to the HVAC Mechanic III or supervisor.
The work requires analyzing equipment symptoms and choosing the most appropriate course of action from established options, while progressively building the skill to recognize when issues exceed standard practice and must be elevated because they involve developing new techniques, interpreting incomplete or conflicting building-wide data, or making decisions that require advanced diagnostic reasoning. Tasks that involve higher skill or more variable conditions are performed only under direction or by HVAC Mechanic III personnel. Although the employee may support senior technicians on complex assignments, the HVAC Mechanic II does not function as a technical expert or project lead, and the nature of the work provides limited opportunities for deviation from established practices or the creation of new methods.
