A2L Refrigerants in Mechanical Equipment: What to Know and How it Impacts Design

Instructor: Joshua Harmon

Description: This session provides an essential overview of the emerging use of A2L (mildly flammable) refrigerants in HVAC and refrigeration systems. With updated codes and standards allowing their use, this class will help building professionals, code officials, and HVAC designers understand the unique properties, safety considerations, and design implications of incorporating A2L refrigerants into mechanical equipment. The session will cover regulatory compliance, installation practices, ventilation requirements, and fire safety measures—equipping participants to assess and apply A2L refrigerants safely and effectively in both new construction and retrofit applications.
