Across the globe, A2L refrigerants are becoming increasingly common as older refrigerants (including R410) are slowly being phased out. HVAC professionals who work with refrigerants must stay informed on the latest regarding the introduction of A2L refrigerants, safety protocols and the like to best serve their customers.
Unfortunately, there are many myths about A2L refrigerants — especially regarding their use in HVAC systems. With a better understanding of these myths (and the realities behind them), HVAC professionals can service systems with greater confidence.
What Are A2L Refrigerants?
Specifically, A2L refrigerants refer to a category of refrigerant that has been used in the United States since 2018. This type of refrigerant has lower overall flammability and toxicity than older classifications that are being phased out. A2L refrigerants have significantly lower global warming potential (GWP), so many countries are switching to reduce emissions and work towards a more sustainable future.
According to the International Code Council (ICC), more than 68 million air conditioners worldwide use A2L refrigerants — and that number is only expected to rise as older refrigerants are gradually phased out.
Debunking Common Myths About A2L Refrigerants
So, what are some of the most common myths about A2L refrigerants? There are several that all HVAC professionals should be aware of.
Myth #1: A2L Refrigerants Require More Maintenance
One myth about A2L refrigerants is that this new type requires much more maintenance than others. However, research suggests that A2L refrigerants can operate for their entire lifespan without the need for maintenance or other interference.
Myth #2: A2L Refrigerants Are More Flammable and Thus Not Safe
There have also been some concerns about A2L refrigerants having the potential to be more flammable than previously used refrigerants. However, it is worth noting that although A2L refrigerants can be flammable, they also have very clearly marked and measured minimum ignition energies (MIEs). As long as you follow proper handling and safety guidelines, the risk of A2L refrigerant actually igniting is extremely low.
Myth #3: A2L Refrigerants Are Compatible With All Equipment
Unfortunately, not all equipment can use A2L refrigerant retroactively. While some can, many systems will need to be retrofitted to use A2L refrigerant, so HVAC professionals must be aware of this while working in the field.
Myth #4: No Additional Training Is Needed to Work With A2L Refrigerants
All HVAC businesses should provide up-to-date training for employees who handle refrigerants as part of their jobs. This training and education should be specific to A2L handling and any specific changes to safety and handling instructions that may apply. With proper training, HVAC professionals can confidently and safely handle this new refrigerant.
