HVAC Technician II

PURPOSE

To improve student achievement by performing Heating, Ventilation, and Air Conditioning (HVAC) level work to 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 mid- 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 perform the moderately complex HVAC repair work, requiring journey level licensing, which involve highly technical practices and repair procedures.

SUPERVISION RECEIVED AND EXERCISED

The HVAC Technician II receives work assignments and general supervision from an assigned Head Maintenance 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

May include, but are not limited to, the following

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.
3. Troubleshooting building HVAC systems in response to trouble calls.
4. Using building plans, equipment documentation, electrical diagrams, controls program logic, control sequences, digital thermometer, and volt/amp multi-meters to assist in troubleshooting.
5. Setting up building trends to monitor building energy usage.
6. Setting up historical data logs from the trends to be used in analyzing energy conservation efforts.
7. Creating and modifing control schemes for efficient control of Building Automation systems, within energy management guidelines and customer requirements.
8. Coordinating and schedule the work of outside contractors.
9. Preparing estimates of materials, equipment and labor required for assignments.
10. Performing maintenance and repair on tools and equipment used in trade’s work.
