Construction, refrigeration and HVAC (which stands for is heating, ventilation, and air conditioning) are rapidly growing industries that offer tremendous demand for those with sufficient training and expertise. According to the US Department of Labor, job opportunities for construction workers and HVAC technicians will grow faster than the national average for most other occupations for a variety of reasons. But in order to work in these industries, it is necessary to receive formal training from technical universities, vocational schools, and college programs that offer relevant coursework.
Given the potentially dangerous working conditions for heating, air conditioning, ventilation, and construction professions, it should be no surprise that most employers require at least an associates degree or higher. A construction worker, for example, will often work in high places installing dangerous electrical wiring or handling high powered tools. An HVAC technician or refrigeration maintenance technician must also develop familiarity with electrical circuitry, air filtration systems, and other areas germane to these particular professions. Coursework might include electrical appliances, temperature regulation, engine parts, engine repair, energy systems, air filtration, and hazardous waste management.
After completing sufficient coursework in heating, air conditioning, ventilation, construction, electrical appliances, or refrigeration maintenance technology, one can work either with an outfit or entirely freelance. Either way, job prospects are good, salary potential is high, and careers advancement is quite favorable.
