Skills for success (Essential Skills) summary
Essential skills are needed for work, learning and life. They provide the foundation for learning all other skills and enable people to evolve with their jobs and adapt to workplace change.
Through extensive research, the Government of Canada and other national and international agencies have identified and validated nine essential skills. These skills are used in nearly every occupation and throughout daily life in different ways.
The application of these skills may be described throughout this document within the skills and knowledge which support each sub-task of the trade. The most important essential skills for each sub-task have also been identified. The following are summaries of the requirements in each of the essential skills, taken from the essential skills profile.
Reading
Refrigeration and air conditioning mechanics read a variety of materials including technical bulletins, manufacturers’ specifications and manuals to obtain detailed information on equipment installation and troubleshooting procedures. They read work orders to ensure that the correct piece of equipment is being installed or maintained according to client requirements. They may also refer to wholesaler catalogues to assist in the selection and ordering of parts and equipment.
Document Use
As part of document use, refrigeration and air conditioning mechanics consult company and work site procedures. They interpret information in tables, charts and graphs, and codes and regulations, and apply that knowledge when performing a task. They also use drawings to understand job requirements. Refrigeration and air conditioning mechanics adhere to hazard signs and warning labels that are part of WHMIS to prevent injury to themselves and others.
Writing
Refrigeration and air conditioning mechanics update logbooks and complete written documents such as service reports, work orders, warranty claim forms, permits, and legislated and company documents. They may prepare sketches and update as-built drawings.
Numeracy
Refrigeration and air conditioning mechanics use numeracy in a range of tasks. For example, they measure lengths of ducting and piping. They calculate areas and volumes of ducting and piping assemblies to meet operating specifications. They use diagnostic and measurement tools to troubleshoot and verify the proper operation of equipment. They compare equipment temperature and pressure trend graphs to equipment specifications and operating parameters to monitor systems. They also estimate time and material costs.
Oral Communication
Refrigeration and air conditioning mechanics communicate with other tradespeople to coordinate the installation, maintenance and service of HVAC/R systems. They interact with clients to identify system requirements and to obtain problem descriptions. They may also call suppliers to order parts, speak with manufacturers’ representatives to obtain technical information and engineers to discuss design specifications.
Thinking
Refrigeration and air conditioning mechanics use problem-solving skills to troubleshoot equipment problems and resolve client issues. They determine the most efficient and economical equipment for a job and repair options available. Refrigeration and air conditioning mechanics plan their work schedule considering factors such as priority, safety, time to complete and travelling time for a job. They schedule maintenance work to minimize down time.
Working with Others
Refrigeration and air conditioning mechanics providing installation, maintenance and service can work independently or as part of a team alongside co-workers, subcontractors and other trades. They interact with clients and others in a professional manner. Refrigeration and air conditioning mechanics mentor apprentices.
Digital Technology
Refrigeration and air conditioning mechanics adjust parameters on automated control systems. They use remote access and on-board functions to monitor and diagnose problems. Refrigeration and air conditioning mechanics use electronic instruments for diagnosis. They may use software, electronic devices and the Internet during the course of their work.
Continuous Learning
Continuous learning is important for refrigeration and air conditioning mechanics due to ongoing changes in technology and an increased emphasis on the environment and energy efficiency. They need to keep informed about new types of equipment, energy sources, materials, computer controls and available client options. They must also keep up-to-date on code and regulation changes that govern their work. Refrigeration and air conditioning mechanics learn through reading manufacturers’ literature and trade journals, and by visiting manufacturers’ websites. They can also take advantage of seminars and information sessions put on by equipment manufacturers, suppliers, unions and their employers.
