To train the present generation of new HVAC technicians, many HVAC instructors have gone back to basic principles. This is in response to the ever increasing complexity of everything to do with HVAC systems. Giving students a solid grounding in the basics of applied thermodynamics, mathematics and electronics is an effective way of helping them understand the more complicated issues. Even the most sophisticated new units are still based on fundamental principles. Being able to apply the fundamentals and the basics of HVAC systems allows students to keep abreast of HVACR industry developments, irrespective of their complexity.
Often, as far as trade schools go, location is very important. For example, technical colleges located in the south east are close to Mitsubishi and LG training facilities. Occasionally, representatives from these companies visit the colleges, which sparks the interests of the students. Hence, as well as learning the basics, students at these colleges get further encouragement from potential employers.
Although trade schools do what they can to prepare the next generation of technicians, funding is not always available for particular kinds of training. Moreover, many of these schools do not teach the very advanced stuff. This is because students who graduate from trade school are classed as junior techs. Hence, they are just taught the fundamentals, and they pick up the more complex stuff over time.
Undoubtedly, in the not too distant future, this sophisticated technology will permeate throughout the whole line of HVAC products. Consequently, there will be increasing numbers of proprietary controls, along with more proprietary software operating these systems. Many manufacturers reserve crucial data for their specific dealers, which means that techs are forced use these dealers to repair the systems. Every manufacturer will try to protect their own products, so techs who want training on these products will have to consult them. Moreover, with controls and systems becoming more complex, IT training will be a standard part of the curriculum for techs before too long. Even the units in residential homes are becoming more computerized.
Most importantly though, the industry will have to attract the right caliber of applicant. Inevitably, technicians will need to be able to go point to point, examine advanced schematics, take various readings to problem solve and switch to ac from dc. While manufacturers are moving towards equipment with more self help features, this still means that whenever a tech is called out, a more difficult fault will need to be fixed. Consequently, the industry will need trained technicians that are sharper than the majority of those that are currently working in the profession.
