2 Lab Hours(s)
Prerequisite(s): HAC 121 and HAC 122
This course provides students with a comprehensive understanding of heat pump technology, operation, and service. Emphasis is placed on the principles of refrigeration and thermodynamics as they apply to heat pump systems, including both air-source and ground-source designs. Students will learn installation practices, electrical and mechanical components, troubleshooting techniques, and performance testing. Topics also include defrost cycles, auxiliary/emergency heat operation, refrigerant management, and efficiency considerations. Hands-on lab exercises will reinforce classroom instruction, preparing students to diagnose, repair, and maintain residential and light commercial heat pump systems. Mini-split heat pumps and variable capacity equipment will also be covered.
