The two-year programs cover electrical and mechanical concepts in greater depth than is possible during shorter courses of study. Some programs focus extensively on advanced electrical and mechanical concepts, while others incorporate mathematics and applied physics course work into the lg صيانة ال جي. Still other programs add information science or computer applications classes; English or technical composition classes, or psychology and business classes to the degree requirements.
Many of the core degree lecture classes are accompanied by labs or practicums where students can refine their skills and learn how to apply them to the workplace. Topics covered in classes can vary and might include: electronics concepts such as voltage and amperage; the science and design of pumps and mechanical motors; pneumatics and compressors; the heating and cooling cycles; and the properties of different metals, chemicals, and elastomers.
Graduates of shorter certification programs or longer degree programs that focus on engineering are eligible for numerous jobs in the HVAC, electrical, and mechanical maintenance fields. Some students begin careers in HVAC, refrigeration, or air conditioning maintenance and repair. Others begin careers in electrical work, and some advance to positions such as electrical journeyman. Some students might specialize in electronics maintenance and repair, including television, small appliance, and computer work. Others still might work as assistant engineers, air-quality controllers, or facilities managers. Students with entrepreneurial drive and talent might wind up as owners of their own businesses.
