In this episode, we’re joined by Anthony from Righttek to break down the fast-changing world of HVAC refrigerants. Anthony gives us a high-level look at A2L refrigerants, what they are, why they’re slightly flammable, and why they’re dominating industry conversations right now.
We explore the key differences between R-32 and R-454B, why manufacturers are choosing one over the other, and how current supply shortages are impacting contractors. Anthony also walks us through the critical new requirements for installation, labeling, and low-voltage wiring, plus the system controls designed to keep homeowners safe.
Whether you’re an HVAC tech still comfortable with R410a or a contractor looking ahead, you’ll get practical advice on the top three things to learn, training and certifications to consider, and how Righttek is helping the industry navigate this major shift.
