Examples Of Work Performed

• Performs maintenance on HVAC equipment and
• Conduct periodic inspections to ensure the efficiency of HVAC
• Checks the performance of thermostats, automatic controls, and pressure
• Cleans, services, oils, and adjusts equipment; tightens fittings; aligns and repacks pumps; and replaces belts.

Description Of Levels

Note: Examples of work and descriptions are meant to progress through the levels. For example, an employee at level III may also perform work listed within the previous levels.

Factors that may distinguish between entry and journey levels include the degree of independence in performing the work, the complexity of the work, the scope of responsibility, and the employee's related work experience, education, and certifications. Employees at the journey level may independently perform the full range of work listed in the examples above or may routinely assist others in that work. They may also assist others in performing work of greater complexity.

HVAC MECHANIC I: Performs entry-level heating, ventilation, and air conditioning (HVAC) mechanic work. Works under close supervision, with minimal latitude for the use of initiative and independent judgment. Employees at this level may rely on direction from others to solve problems that are not standard. Employees at this level may have limited experience and spend the majority of their time performing simple to routine work following standard procedures.

Note: Any senior-level employee (levels II-III) may serve in a lead role. Senior-level employees may perform the full range of work identified in the levels preceding their own, may provide guidance to other HVAC mechanics, and may coordinate or oversee HVAC projects. Factors that may distinguish between senior levels include the scope of responsibility, oversight, and authority; the complexity of the work; and the employee's related work experience, education, and certifications.

HVAC MECHANIC II: Performs advanced (senior-level) heating, ventilation, and air conditioning (HVAC) mechanic work. Valid North Carolina HVAC License (H1-T, H2-T, H3-T) and/or EPA Clean Air 608 Refrigerant Recycling, Recovery, and Reclamation Certificate (or equivalent) required. Work involves coordinating the installation, repairs, and overhaul of HVAC equipment and systems based on work orders and preventative maintenance activities. Works under limited supervision, with moderate latitude for the use of initiative and independent judgment. Employees at this level may:

• Overhaul and service HVAC equipment, including air compressors and pumps associated with HVAC equipment and systems.
• Repair and replace worn or broken parts on condensers, compressors, and water and vacuum pumps.
• Repair or adjust valves, piping connections, fittings, and
• Test equipment for refrigerant leak, charging, and metering device
• Remove and install motors, thermostats, and
• Adjust expansion valves and add gas to refrigeration
• Check gauges and perform preventive maintenance
• Maintain records and prepare reports on repairs and service to
• Monitor energy consumption of HVAC systems and recommend increased energy efficiency in operations.
• Set up and install complex HVAC electrical
