This refrigerant diagnostics session is a full-day review of the refrigerant circuits and components in split-system air conditioners and heat pumps. Participants will understand circuit flow and learn test measurements that assure the most accurate and time-effective diagnosis of refrigerant issues. Using various OEM charging charts to determine system conditions in multiple exercises will reinforce the use of pressures, superheat, and subcooling to identify system failures. The importance of proper indoor airflow and an easy airflow measurement technique is discussed. Compressor diagnostics and replacement procedures are included. Employ a consistent test strategy for any indoor comfort system complaint using the procedures learned in this session.

*Bring your manifold gauge set and safety glasses for an equipment calibration test during the class day.

Topics Covered:

 Circuit analysis using superheat and subcooling
 Evaporator heat load variations
 Testing thermostatic expansion valve flow and response
 Compression ratio and sound characteristics
