Heating, Ventilation, and Air Conditioning (HVAC)

The Heating, Ventilation, and Air Conditioning program is a Certificate of Achievement program designed to prepare students for a career in Heating, Ventilation, and Air Conditioning. Program performance standards for certification will be in accordance with those set forth by the National Center for Construction and Research (NCCER). Career opportunities for graduates include employment with commercial heating and air conditioning contractors, residential mechanical contractors, parts and equipment distributors, large commercial and industrial facility maintenance departments, hospitals, custom design and new construction markets. Student Learning Outcomes: 1. Students will use the proper instrument to measure voltage, current, and resistance. 2. Students will identify the components of induced-draft and condensing furnaces and describe their functions. 3. Students will describe the basic pattern of refrigerant flow and the changes of state that occur in the refrigerant cycle. 4. Students will test AC components, including transformers, capacitors, and motor windings. 5. Students will calculate superheat and adjust an expansion valve to obtain the correct superheat. 6. Students will measure and record the electrical and mechanical operating parameters of an operational compressor. 7. Students will properly install, align, and adjust a drive belt. 8. Students will select the appropriate drill bit and install an anchor in brick or concrete. 9. Students will interpret control circuit diagram. 10. Students will perform electrical test and troubleshooting. 11. Students will identify the types of common piping configurations used with commercial hot-water and chilled-water hydronic systems. 12. Students will perform a building indoor air quality (IAQ) inspection/evaluation. 13. Students will interpret operating data received through building management systems software. 14. Students Identify and interpret architectural drawings. 15. Students will create a basic heating and cooling system design from provided plans

It is anticipated that at the conclusion of year 1 and thereafter there will be 20 to 30 student completers for the certificate.

The goals of the Food Science and Food Safety Program are to: Heating, Ventilation and Air Conditioning program prepares students for careers in the HVAC industry including maintenance, new construction, and retrofit installations. The curriculum is designed to align with the National Center for Construction Education and Research (NCCER) certification. Completion of the certificate qualifies students to enter the professional job market. The preceding goals will be met through the following student-performance objectives: A. Explain the basic principles of heating, ventilation, air conditioning and refrigeration. B. Describe the principles that guide HVAC/R installation and service techniques. C. Convert units of measurement from the inch-pound system to the metric system, and vice-versa. D. Describe the fundamentals of electricity. E. Explain how to safely test various AC-powered devices. F. Identify and describe the operating characteristics of various compressor types. G.
