Course Description
Addendum to Course Description
Students will study the fundamentals of automotive heating and air conditioning systems. This includes theory, operation, safety factors, components, electrical and vacuum controls. Proper handling of refrigerant and antifreeze will be discussed as well as government regulations concerning their use. Correct use of air conditioning recovery and recycling equipment will be presented. Students will test, diagnose and repair problems on customer and school owned vehicles.
Intended Outcomes for the course
Upon completion of the course students should be able to:
- Perform heating and air conditioning system inspection, maintenance, adjustments and repair with limited supervision.
- Perform engine cooling system maintenance, diagnosis and repairs as related to heating and air conditioning with limited supervision.
- Communicate professionally with employers, customers and co-workers using industry standard language and following industry standard protocols.
- Access and utilize repair information in a rapidly changing technology.
- Develop and implement strategies and processes to solve heating and air conditioning repair problems.
- Perform heating and air conditioning repair to professional and ethical standards.
