Products: VRF and Ductless Solutions

As the HVAC industry transitions away from R-410A, A2L refrigerants have become the new standard for VRF systems - bringing with them a wave of uncertainty, misinformation, and hesitation among engineers. This webinar directly confronts the most common myths surrounding A2L VRF systems.

We will examine misconceptions around everything from safety and flammability concerns to VRF equipment and design changes. Attendees will leave with a clear understanding of what has actually changed with A2L VRF. Whether you have been cautiously watching the transition or actively designing A2L VRF systems, this session will give you the technical confidence to move forward.

Learning Objectives:

Understand what A2L flammability classifications realistically mean for building safety.
Apply updated ASHRAE Standard 15 requirements to A2L VRF system design, identifying what has changed from previous code cycles and how those changes affect your project design.
Identify key equipment and design differences in A2L VRF systems, including new component requirements, system configurations, and engineering considerations.
Understand what changes A2L VRF service really requires.
