In Grade 12, students will explain and identify heating fuels (natural gas, propane and heating oil), how they burn and how to safely control the burn, as well as EPA certification requirements in order to pass certification exams. Instruction in different types of air conditioning systems, heat pumps, unitary, central station and split systems is provided in dividing needs and trouble-shooting service. Students will demonstrate their ability to use code books and apply code requirements at apprentice entry-level. Skills practiced in lab and on in-school and outside production work for customers include installation of the different systems and testing operation and airflow. The proper handling of refrigerants, including recovery, recycling and reclaiming, are studied and practiced. Students continue to receive instruction in safety requirements and demonstrate sound safety practices. Students will demonstrate the ability to complete a job application, to interview and to perform entry-level job readiness and trade skills. Students reaching an acceptable level of proficiency may be eligible for Work-based Learning (WBL). Each student will take the National Occupational Competency Testing Institute (NOCTI) exam, which is a performance-based test.
