GENERAL DEFINITION

This is supervisory mechanical work in the maintenance, repair and operation of heating, ventilation, air conditioning and/or refrigeration systems and components.

An employee in this class supervises the activities of a group of mechanics engaged in a variety of tasks associated with the maintenance of facility climate control equipment. Employees in the refrigeration and heating specialty supervise the servicing of air conditioning, refrigeration, ventilation and heating systems and related equipment while those in the utility specialty supervise the maintenance of HVAC and related primary and peripheral utility components. Planning, assigning and reviewing subordinates’ maintenance and repair work to ensure the proper operation of assigned equipment are significant aspects of the work. Work involves exposure to disagreeable environmental conditions and moderate physical effort. Work is performed under the supervision of an administrative or maintenance superior.

ALLOCATING FACTORS (The following conditions must be met for a position to be allocated to this class.)

• The position must plan, assign and review the work of skilled HVAC mechanics in maintenance and repair work.

• The position must supervise a minimum of three subordinate HVAC mechanics.
