Curriculum

Air Conditioning & Refrigeration Technology

Employment in the field of air conditioning and refrigeration technology is expected to increase as more homes and commercial and industrial buildings are built. Installations of energy saving heating and air conditioning systems in older homes and buildings will also contribute to an increase in employment. This field offers a wide variety of career opportunities dealing with the technology of refrigeration, air conditioning and heating techniques in homes, work environments, transportation, food preservation and health.

Course topics include:

• Applied electricity and electronics
• Basic drafting
• Design and control systems
• Air movement and balancing

Admissions Requirements

In addition to admissions requirements listed under the Admissions Information, it is recommended that the student have completed two units of high school math, including one unit of algebra and one unit of high school science, preferably physical science.
