REFRIGERATION AND AIR CONDITIONING SERVICE TECHNICIAN3293N2 Pay Grade: 19 DEFINITION OF WORK Summary This is skilled mechanical and electrical work performing the installation, maintenance and repair of small, package or window refrigeration and air conditioning units and related air handling equipment; or assisting highly skilled Refrigeration and Air Conditioning Service Technicians II in the maintenance of large tonnage, complex or multi-system refrigeration and air conditioning equipment. Standard Classification Factors Supervision Received - LEVEL C: "Under direction " Employees at this level usually receive a general outline of the work to be performed and are generally free to develop their own sequences and methods within the scope of established policies. New, unusual, or complex work situations are almost always referred to a superior for advice. Work is periodically checked for progress and conformance to established policies and requirements. Difficulty - LEVEL B: Average Where the employee is confronted with a variety of duties susceptible to different methods of solution which, in turn, places a correspondingly higher demand upon resourcefulness and concentration. Positions which require the analysis and evaluation of raw data and the rendering of conclusions would, in many instances, fall into this category. Complexity - LEVEL B: Work is of a structured nature including duties that have several related steps. This level involves simple analysis of data, identification of easily distinguishable facts and recognition of differences in related situations. Workers at this level exercise limited independent judgment in determining methods or procedures to be used in making minor decisions. Work is normally controlled by frequent review and consultation with supervisors. When guidelines exist at this level, they are usually specific and aid in determining an approach to problems or situations. Workers at this level must be able to identify basic differences in situations to determine the actions which need to be taken. Consequence of Actions or Decisions - LEVEL C: Consequences of actions or decisions at this level are limited in scope and effect as the work is reviewed occasionally. Errors may cause moderate inefficiency. Costs due to errors may be significant. Contacts - LEVEL A: The purpose of the contact is to obtain, clarify, give or screen established factual information, regardless of the type (i.e., easily understood or technical) within a well-defined relationship. Normal communication skills are required. Physical Demands - LEVEL C: The work requires moderate physical exertion. Environmental Conditions - LEVEL B: The work environment involves moderate hazards, risks or discomforts. Exposure to minor deviations from pleasant environmental conditions is normal. Minor to serious injuries are possible. Supervision/Leadership - LEVEL B: Involves functional leadership responsibility. As a "senior worker", performing essentially the same or similar work as those overseen, responsibility includes training, instructing, scheduling and reviewing. As a "project leader" may be responsible for a phase(s) of a single project which includes planning, coordinating and reviewing the work of others. This level may also involve limited administrative responsibility such as participating in the evaluation of work performance.
