LAC 28:CV.2305. Air Conditioning Certification

A. Air conditioning (A/C) certification establishes a basis for all other certifications involving the vapor compression refrigeration system. Today's systems use new refrigerants and oils compared to units built just a few years ago. A properly maintained system should deliver years of trouble-free operation. However, improper service techniques or failure of one simple component will almost always lead to catastrophic failure of the system. B. Who Should Be Certified. Any technician responsible for diagnosis and repair must possess a strong background in refrigeration systems. C. Competencies covered: 1. theory of heat, temperature, and pressure; 2. physical states of matter and change of state; 3. refrigeration and refrigerants; 4. refrigerant and oil management; 5. refrigeration applied to air conditioning; 6. system evacuation; 7. leak detection; 8. tubing and piping practices; 9. tool usage and calibration; 10. equipment maintenance; 11. system charging; 12. safety.
