Advisor: Jim Harris (Gila Pueblo)
This program combines hands on laboratory training with applied theory to develop the skills needed to install, service, and troubleshoot residential and commercial HVAC R systems. Coursework emphasizes electrical fundamentals, refrigeration principles, system diagnostics, and industry safety standards, along with technical training relevant to commercial refrigeration and air conditioning systems. Students also receive advanced instruction in heat exchange, flow devices, and commercial level troubleshooting. Graduates are prepared for entry level technician positions and are eligible to pursue industry recognized certifications.
Program Learning Outcomes
1. Identify hazards and implement OSHA-/industry-approved safety procedures and PPE; demonstrate working knowledge of applicable local, state, and federal codes and refrigerant regulations.
2. Describe air mixing and airflow dynamics and explain the operation and applications of variable refrigerant flow (VRF) systems.
3. Explain thermodynamic heat exchange principles and evaluate the function, performance, and diagnostics of evaporators across system types.
4. Identify and analyze advanced refrigeration components (e.g., electronic expansion valves, hot-gas bypass, oil management) and differentiate among specialized applications (e.g., low-temp, rack, cascade, ice machines, display cases).
5. Formulate and document an installation or troubleshooting plan that selects proper tools and instruments, specifies target measurements, and applies systematic diagnostic procedures—including those specific to ice makers and commercial refrigeration.
6. Analyze the environmental implications of HVAC R decisions—refrigerant selection, recovery, leak mitigation, and maintenance—and justify practices that support sustainability and regulatory compliance.

Notes
Any developmental courses (such as ENG 100 and MAT 120) must be taken in addition to the above during this semester as prerequisites for later courses.
The foregoing is a recommended, or suggested, sequence of courses. If a student enters the program in the Spring, or transfers credit in, the above would have to be modified.
