Course Number and Title: ACR 104 Residential Climate Control
This course introduces students to residential air conditioning and heat pump systems. Design characteristics, components, operation, and service are covered. Emphasis is placed on proper installation and troubleshooting procedures. Hands-on training with emphasis placed on mastery of skills and competency in assigned tasks is provided.
- Investigate the function of components used in air conditioning systems. (CCC 1, 4; PGC 2, 3, 4)
- Examine conditions that affect the operations and efficiency of air conditioning systems. (CCC 2, 6; PGC 4)
- Troubleshoot and service air conditioning and heat pump systems. (CCC 2, 3, 4, 5; PGC 3, 4, 6)
- Evaluate installation procedures and the operation of a typical air conditioner and heat pump system. (CCC 1, 2; PGC 1, 2, 5, 6, 7)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.
