Beginning in 2025, the HVAC industry is transitioning to A2L refrigerants in response to new environmental regulations aimed at reducing global warming potential (GWP). Many existing HVAC systems can continue running as they are for the time being. Still, business owners should start preparing by learning about the new refrigerant and start considering AC replacement options that favor more eco-friendly refrigerant alternatives. In the following article, we address the most common questions from owners and provide helpful tips on the 2025 refrigerant change for businesses.
What Does Refrigerant Do?
HVAC systems rely on refrigerant, a chemical that transfers heat to keep your space comfortable. It travels through copper lines, turning from liquid to vapor as it absorbs heat indoors and releases it outside. Simply put, without refrigerant, your system can’t do its job—making it a key part of your building’s climate control.
What is R-410A Refrigerant?
For years, R-410A has been the standard in commercial HVAC systems, taking over from R-22 thanks to its ozone-friendly properties. But since it has a high global warming potential, it’s now being phased down. The EPA’s new environmental guidelines are pushing the industry toward A2L refrigerants, which offer a lower impact on the environment.
What Refrigerant is Replacing R-410A?
To meet updated EPA guidelines, the HVAC industry is switching to A2L refrigerants, which have much lower global warming potential (GWP). While A2Ls are mildly flammable, their reduced environmental impact makes them a smart choice for improving energy efficiency and sustainability in HVAC systems.
What Are A2L Refrigerants?
A2L refrigerants are known for having lower GWP, being less toxic, and only mildly flammable—making them a safer and greener alternative to R-410A. They’re designed to reduce environmental impact while still delivering reliable cooling.
R-454B and R-32 are the primary A2L refrigerants that will be used in place of R-410A in future commercial HVAC systems.
Frequently Asked Questions About New Refrigerants for Businesses
As A2L refrigerants become the new standard, business owners are raising important questions about what this means for their equipment, costs, and overall operations. Here’s a look at the key concerns companies are facing.
Will I Need to Replace My Current HVAC System to Meet the A2L Requirements?
You won’t need to make changes immediately. Systems using R-410A or other existing refrigerants can still operate normally. The new A2L refrigerants mainly impact future installations. When your system needs replacing, you’ll need to upgrade to one that uses an A2L refrigerant.
Will switching to A2L refrigerants increase my operating costs?
This change isn’t likely to raise your operating costs. A2L refrigerants like R-454B and R-32 are more energy-efficient, which can help lower your energy use and utility bills. Plus, many systems that use A2Ls run more reliably and may require less maintenance over time.
Are A2L Refrigerants Safe for My Business?
Yes, A2L refrigerants are safe to use in commercial HVAC systems. Although they’re labeled as mildly flammable, they’re hard to ignite and far safer than older options like propane. These refrigerants have gone through extensive testing and, when installed by Aspen Aire’s trained professionals, your system will meet all safety codes and regulations.
Do I Need New Equipment for A2L Refrigerants?
No, you don’t need to replace all of your current equipment. Existing systems that still work can keep running as usual. A2L refrigerants will only be required for new HVAC installations or when outdated systems are replaced. Planning ahead can help you manage future upgrade costs more effectively.
