The HVACR industry is making the transition to more environmentally friendly (lower GWP) refrigerants. With this transition, HFCs are being phased down and there has been a growing acceptance of the use of A2L refrigerants due to their lower flammability and toxicity.

In this class you will learn:

• The facts about R-45B and A2LS
• The upside to R-454B Refrigerants
• Combustion and thermal decomposition of refrigerant
• Superheat vs. subcool R454B
• Hazards of R-454B
• Field Procedures of A2LS
• Peace of mind using R-454B
• 454B equipment update and information
