As we head toward 2025, big changes are coming to the HVAC world, and you might have already heard a thing or two about new refrigerants. One of the questions we get a lot at Dinomite is about safety, particularly when it comes to the flammability of the new refrigerants like R-454B. So, should you be worried? Let’s dive in and break it down for you.
What Are These New Refrigerants?
To meet the EPA’s new environmental regulations, the HVAC industry is moving away from R-410A, a refrigerant with a higher Global Warming Potential (GWP). Starting January 1, 2025, all newly manufactured air conditioning units will use refrigerants with lower GWP, like R-454B and R-32. While these new refrigerants are more eco-friendly, they also come with the label “A2L,” which means they’re classified as “mildly flammable.”
We understand that when you hear the word “flammable,” you might picture your AC turning into a fire hazard. But that’s far from the truth, and we’re here to explain why you don’t need to lose sleep over this.
What Does “Mildly Flammable” Really Mean?
Let’s clear up what “mildly flammable” means. The A2L classification for refrigerants like R-454B is mostly a technical label used by the industry to identify how difficult it is to ignite a substance. In reality, these refrigerants are very hard to ignite. For context, it would take a significant and very unlikely set of circumstances for these refrigerants to catch fire.
To put things into perspective, you probably have many A2L-rated substances in your home already without even thinking about it. For example, hairspray or cooking spray have similar flammability ratings, and they’re not something we worry about on a daily basis. The same goes for these new refrigerants — they’re designed to be safe and manageable in your air conditioning system.
Built-In Safety Measures
Now that we’ve addressed the term “mildly flammable,” let’s talk about the safety measures in place. The new air conditioning systems being built for R-454B and R-32 refrigerants come equipped with advanced safety features that make them just as safe, if not safer, than the systems you’re already using.
These systems will have built-in leak detection sensors, pressure relief devices, and ventilation mechanisms to ensure that any issues with the refrigerant are caught early and resolved without risk to your home. The HVAC industry is also rolling out strict installation standards to ensure that every system is set up with safety in mind.
When you buy a new AC unit after 2025, you’re not only getting a product designed for lower emissions, but one that’s been built with advanced technology to ensure your comfort and safety.
How Will This Impact You?
From a homeowner’s perspective, the introduction of A2L refrigerants won’t feel much different than using your current system. As always, the most important thing is to ensure that your system is installed and maintained by licensed professionals like the experts at Dinomite. With professional installation and regular checkups, you can be confident that your AC system will run safely and efficiently for years to come.
If your system is on its last legs and you’re wondering whether to replace it now or wait until 2025, there’s no need to rush just because of the refrigerant change. R-410A systems will still be serviceable for a long time, and our team can help you determine whether it’s more cost-effective to upgrade now or later.
