HVAC Technician III

PURPOSE

To improve student achievement by performing advanced journeyman Heating, Ventilation, and Air Conditioning (HVAC) level work to design, install, operate, maintain, repair and integrate multifaceted energy systems that generate heat, ventilation, air conditioning, refrigeration (HVAC/R) and their associated system controls which include direct digital and pneumatic.

CLASS CHARACTERISTICS

This is the advanced journey level class in the HVAC Technician series. Positions at this level are distinguished from other classes within by the level of responsibility assumed, the complexity of duties assigned, and the requirement of maintaining local/state licensing.

Employees in this classification may install new equipment and building services. Employees perform the most complex HVAC repair work, requiring advanced journey level licensing, which involve highly technical practices and repair procedures. Provides coordination and technical assistance to lower HVAC Technician classifications. Serve as mentor in approved HVAC Technician apprenticeship program.

SUPERVISION RECEIVED AND EXERCISED

The HVAC Technician III independently plans and coordinates all work involving Computer Controlled HVAC/R Systems. Employees receive work assignments and general supervision from an assigned Head Electrical Worker. Work is assigned orally and/or through an electronic work order system which may include control diagrams, blueprints, and/or maintenance instructions.

Work is periodically reviewed while in progress and/or upon completion for quality and compliance with standards. Supervisory control typically does not extend beyond approval of priorities, schedule and final work product.

ESSENTIAL FUNCTIONS OF THE JOB

1. Administering the operation of HVAC systems in district owned and operated buildings and facilities.
2. Using computers to monitor HVAC systems, temperatures, and pressures. Troubleshooting building HVAC systems in response to trouble calls.
3. Using building plans, equipment documentation, electrical diagrams, controls program logic, control sequences, digital thermometer, and volt/amp multi-meters to assist in troubleshooting.
4. Designing new control systems or replacement systems and the sequences of the equipment operated by those systems.
5. Setting up building trends to monitor building energy usage.
6. Creating and maintaining historical data logs from the trends to be used in analyzing energy conservation efforts.
7. Creating and modifying control schemes for efficient control of Building Automation systems, within energy management guidelines and customer requirements.
8. Serving as mentor in district approved apprenticeship program(s). Coordinating and schedule the work of outside contractors.
9. Preparing estimates of materials, equipment and labor required for assignments. Performing maintenance and repair on tools and equipment used in trade’s work.
