This program is designed to instruct students in the refrigeration cycle, electrical wiring diagrams, and troubleshooting. Students train on oil, gas, and electric furnaces and air-cooling equipment and learn to analyze equipment and diagnose problems. Students are prepared to begin employment in the field after completing the course, whether part-time during senior year or full-time after graduation. Alternatively, many students choose to pursue different trades courses in junior and senior years in order to become cross-trained in different skill sets and enhance their employability.
