High School Students will learn fundamental heating and air conditioning concepts and system diagnosis. This will include heater cores, evaporators, expansion valves, condensers, tubing, orifice tubes, system charging and environmental impact of R-12 AND 134 gases.
Adult Students this course covers the automotive heating systems, air conditioning systems, parts identification and function, and system operations. Also in this course the student will cover the refrigerants used in air conditioning systems and how to identify them along with Federal Legislation. Temperature control components and systems will also be identified. The student will learn about the cooling system components, identifying coolant type, checking and adjusting coolant levels as well as checking and replacing coolant hoses. The student will also learn to flush and pressure test the coolant system. The student will learn servicing procedures and how to operate testing and servicing equipment. The student will learn to evacuate and recharge air-conditioning systems using the proper refrigerant. The student will learn to evaluate and determine necessary action for compressor and clutch assemblies, and how to perform the replacement of these parts. The student will learn to perform component replacement, such as the receiver drier, expansion valve, orifice tube, hose assemblies and O-rings. The student will learn to troubleshoot heating and air-conditioning systems operation and how to evaluate climate control systems. This course covers both the electrical and vacuum controls. The student will also learn to diagnose air conditioning system failure concerns, such as the protection device interrupt system, temperature control problems, climate control systems, electrical controls for heating and ventilation, load cut-off systems and other climate control malfunctions. The student will also learn to evaluate and perform the necessary action of control panel assemblies, control cables, ducts, doors and outlets.
