Program Manager - Research & Innovation CLEAResult Condon, Oregon
This session explores how the HVAC industry is navigating the transition to low‑GWP A2L refrigerants and what these changes mean for equipment design, installation practices, and field verification. We’ll cover the fundamentals of R‑454B and R‑32, shifts in, new safety and leak‑detection requirements, and why contractors should reconsider update evacuation processes, levels, documentation, and QA methods. The session also highlights modern diagnostic approaches—including hoseless tools and capacity‑based testing—to ensure reliable performance in today's inverter-driven systems. A brief overview of MS Check illustrates how simplified field protocols fit into the broader move toward less‑invasive verification.
Learning Objectives:
By attending this session, attendees will:
Understand how A2L refrigerants (R‑454B, R‑32) change system design, safety requirements, and installation practices.
Apply modern commissioning methods—deep vacuum, decay testing, and hoseless diagnostics—for A2L and inverter systems.
Verify heat pump and mini‑split performance using non‑invasive or less-invasive testing and capacity‑based checks (including MS Check).
