Book excerpt: This essay sheds light on how to become an HVAC technician, explicates how to be highly successful as an HVAC technician, and elucidates how to earn revenue as an HVAC technician. While becoming an HVAC technician may seem be an eminently cumbersome, expensive, time-consuming, and daunting undertaking, it is viably possible to become an HVAC technician. Much to the relief of prospective HVAC technicians, it is possible to become an HVAC technician in four to five year time span and the journey to become an HVAC technician is not as lengthy as the journey to pursue certain other occupations, such as the occupations of a medical doctor or attorney. The pathway that a prospective HVAC technician can follow to become an HVAC technician is fraught with challenges that are not a cinch to surmount. It can be arduous to fulfill the duties of an HVAC technician. HVAC technician skills are highly desirable skills to possess. As of October of 2021, only an infinitesimal fraction of one percent of the global population are employed as HVAC technicians. In the US, for instance, less than 395,000 are employed as HVAC technicians even though the us population is comprised of over 328,000,000 people as of October of 2021. As of October of 2021, less than .1205% of people in the US are employed as HVAC technicians. This means that out of 830 random people in the US, about only one person at most would be employed as an HVAC technician as of October of 2021. As of October of 2021, it was estimated that there were more medical doctors and attorneys in the US that HVAC technicians even though it takes far more years to fulfill the ample mandatory requirements to become a medical doctor or attorney than it takes to fulfill the mandatory requirements to become an HVAC technician. As of October of 2021, the economy is unequivocally in dire need of more HVAC technicians, especially since the temperatures in houses, condominiums, and the establishments of businesses cannot be precisely controlled by people without the usage of air conditioning systems and heating systems in these indoor settings. Without air conditioning systems and heating systems, the indoor settings in the world would not be temperate controlled environments and would be all the more prone to have adverse temperatures. HVAC technicians perform essential functions since they ensure that air conditioning systems, heating systems, and ventilation systems are functional. The job of an HVAC technician is not for a faint of heart to be pursuant of and can be difficult to carry out. HVAC technicians fulfill a vast variety of job functions that extend beyond the ambit of them ensuring that air conditioning systems, heating systems, and ventilation systems are functional. The job functions of an HVAC technician are multitudinous and are of eminent importance for an HVAC technician to perform. HVAC technicians “install, maintain and repair” air conditioning systems, heating systems, and ventilation systems “in both residential and commercial properties”. Additionally, HVAC technicians are also expected to diagnose air conditioning systems, heating systems, and ventilation systems for “mechanical faults and electrical faults”. Moreover, HVAC technicians are also expected to know how to sedulously “maintain daily logs and records of the maintenance checks of HVAC systems”. HVAC technicians should strive to competently handle customer queries in a punctual manner. HVAC technicians should also aim to resolve issues with HVAC systems in an expeditious manner. People cannot function optimally without having access to functional HVAC systems. The occupation of being an HVAC technician does not have optimal working conditions. In order to be an HVAC technician, a person needs to be able to cope with working in environments with adverse temperatures and cope with performing a substantial amount of strenuous manual labor in uncomfortable working conditions to be able to complete HVAC technician jobs. Working as an HVAC technician can also be physically exhausting. Working as an HVAC technician can also often be an eminently unpleasant job to endure performing, especially when you are working in environments with adverse temperatures for a prolonged period of time and are performing a substantial amount of strenuous manual labor.
