This course will be a 2-hour long lecture/lab combination class. Some of the time will be spent lecturing using academic course material. The rest of the time will be spent in a lab setting practicing the application of skills learned in theory. From motor theory to HVAC/R components to the wide varieties of electrical diagrams, the course focus is to give the student a strong background in electrical understanding necessary to install and service heating, ventilating, air conditioning and refrigeration systems. Special emphasis will be applied to learning the types of motors and what the differences are in their composition and behavior. We will also explore capacitors and motor starting devices. This class may require participating in several field trips for further understanding of the profession. Prerequisite: Satisfactory completion of REFG 121 and REFG 123 or equivalent. (S)
