Working in the HVAC industry requires a thorough knowledge of how “heating and air-conditioning systems control the temperature, humidity, and the total air quality in residential, commercial, industrial, and other buildings.” Another area that requires familiarity is refrigeration systems. Refrigeration systems allow the storage and transportation of food and perishable items. HVAC technicians are responsible for troubleshooting the issues in these various areas and installing and repairing the systems involved.
HVAC technicians work in homes, offices and any institution requiring a climate-control system. Most work is done in hot and cold weather, or in buildings that are uncomfortable due to the lack of heat or too much heat. Technicians run the risk of being electrocuted or burned, or experiencing other injuries on the job. For example, working with refrigerant can lead to frostbite, skin damage or blindness if it is not handled properly. Most workweeks are 40 hours, but there can be overtime and irregular hours. In addition, technicians regularly work weekends and holidays.
No matter what path a student takes in obtaining education as an HVAC technician, the core classes will be similar. The main topics covered are air distribution, HVAC and refrigeration electronics, pneumatic HVAC systems, thermal controls, and HVAC and refrigeration safety. HVAC technicians are required to earn an EPA (Environmental Protection Agency) certification when employed in the industry. Some technicians have been lucky enough to get by with simply becoming an apprentice and starting out that way. However, most hiring companies will require formal training and an EPA certification.
The associate's program is intended to be completed within a two-year period. In addition to HVAC courses, students will be required to complete general education courses. The associate’s degree can be completed through a local community college or through a private school such as San Joaquin Valley College.
Technical programs focus on HVAC core courses and exclude general education. These programs mainly offer certificates of completion from a technical school. The classes taken at these schools do not transfer to other schools. This means if a student starts with a particular school, he must finish with that school to earn a certificate. Institute of Technology is a school where students may complete their program within 9 months. There are various other technical schools throughout the state of California.
