Everyone’s talking about refrigerant changes, but the real story is the shift from A1 to A2L. Once you understand toxicity and flammability classes in ASHRAE 34, the transition makes a lot more sense. #hvaclife #HVACMaintenance #hvacservice #hvac | Tony Mormino

What does A2L really mean? ASHRAE’s classification makes it simple: A/B = toxicity level 1–3 = flammability level Older A1 refrigerants (like R22) are non-toxic and non-flammable, while non-toxic and mildly flammable A2Ls are the next step in efficient, sustainable cooling. #HVACTech #Refrigerants #ASHRAE #CoolingInnovation #MROSupplier | Chadwell Supply
