Technological advances in the HVACR industry have made it necessary for educators to come up with more innovative ways to train the new crop of service technicians. With HAVC systems controls and systems becoming more complex, educators have to train students on the basics and fundamentals before offering advanced training.
Although manufacturers are producing complex HVAC systems, the physics of applied thermodynamics and electrical principles remain unchanged. This implies that trained technicians who grasp the basic and fundamentals of HVAC systems can take care of the newer and complex systems.
HVAC instructors usually work within budgets that are not sufficient enough for them to acquire equipment and rely on electronic simulation. Some of the training grounds, which are conveniently located near HVAC systems manufacturers’ sites, can benefit from the experience and expertise of the instructors.
Instructors should be able to impart the basic and fundamental principles of HVAC working, and at the same time cultivate the trainee’s interest to aspire to work with modern complex systems. Today’s manufacturers are using advanced controls operated using computerized systems, some of which are proprietary. This development, according to many HVAC instructors, will eventually lead to revision of the syllabus to include IT training.
The HVAC industry needs sharper trained technicians who can work the complex systems produced by manufacturers. Proper training guides can only be developed by consulting the manufacturers, instructors and contractors. A holistic approach that incorporates instructor training and manual guides is crucial to trainees understanding the working of HVAC systems.
The industry is headed toward proprietary controls throughout the HVAC system. The complexity is further deepened by proprietary software running the units. This further complicates the HVAC instructor’s duty of setting a standardized training program. On one end, it means specialization in a particular unit leaving out the rest or having to take general units. Generalization will mean that service technicians will not delve very deep into the systems. The general rule of trade school is to bring out better technicians that understand the basics and that can later be trained on the advanced stuff.
Even though technology has changed a lot in the HVACR industry, the role of instructors remains vital and virtually unchanged. The HVAC instructor cannot be replaced by instructional tools. This is partly because the basic instructional methods are best suited to produce better qualified trained technicians. It is only through methods like explanation, illustration, reviewing, reciting and testing that instructors can impart the fundamentals and the basics of HVAC systems to students.
