Product Description
Vehicle manufacturers must comply with environmental regulations that directly affect the design and of the HVAC system. As R-1234yf becomes the mainstream refrigerant, technicians must adapt to the differences in service and diagnosis. More complex controls are networked together to operate the HVAC system, and these must be part of the diagnosis. Technicians must understand the entire system to consistently provide their customers with the comfort level they demand.
The goal of this class is to refresh technician knowledge of refrigeration principles as they relate to diagnosing a fault in the refrigerant portion of the HVAC system. Effective diagnosis, component replacement, and service will be demonstrated on R-1234yf vehicles. We will teach system and schematic analysis to improve the technician’s diagnosis of cooling fan, compressor, and in-car controls which all play a role in keeping the customer happy.
After completing this class, a technician will be able to:
- Identify new technologies and their impact on HVAC
- Properly diagnose and service R-1234yf systems
- Properly replace HVAC components
- Perform correct HVAC service
- Diagnose cooling fan and airflow issues
- Diagnose in-car HVAC controls
