"Flammable" Refrigerant Facts for Residential HVAC

In this training class, Bryan Orr from HVAC School provides key facts and information for HVAC technicians about the transition to mildly flammable A2L refrigerants like R-32 and R-454B being adopted for residential and light commercial systems. He covers the reasons behind the phase-down of higher global warming refrigerants like R-410A, the differences between A2L refrigerants and propane, similarities and differences compared to R-410A, changes to equipment and components, best practices for handling mildly flammable refrigerants safely, evacuation procedures, leak testing, and more. This is a must-watch for any residential HVAC tech getting ready to work on new A2L systems in the coming years. Bryan dispels misinformation and fear-mongering around these new refrigerants while still emphasizing the proper precautions that should be taken.
