The HVAC industry is in the middle of a transition that will affect every manufacturer, technician, and facility manager in the country. For years, R-410A has been the refrigerant of choice in commercial and residential systems. Soon, however, it will no longer be available in new equipment.
Why? The Environmental Protection Agency (EPA) is phasing out high global warming potential (GWP) refrigerants as part of its broader effort to reduce greenhouse gas emissions. In their place, the industry is adopting new alternatives—mainly A2L refrigerants like R-454B and R-32.
These new refrigerants promise to be more environmentally responsible and, in many cases, more energy efficient. But their introduction also raises new challenges, from equipment redesigns to training requirements and higher upfront costs for consumers.
If you’re responsible for keeping a facility comfortable and productive, understanding this transition now will help you plan strategically and avoid costly surprises.
Why the Change Is Happening
The HVAC industry has always evolved in response to environmental and regulatory pressures. In the 1990s, we moved away from ozone-depleting refrigerants like R-22. Now, the focus is on global warming potential.
-
R-410A’s problem: Though widely used and effective, R-410A has a GWP of around 2,000. That means one pound of R-410A has the same warming effect as 2,000 pounds of carbon dioxide.
-
A2L refrigerants: Options like R-454B and R-32 have GWPs that are 70–80% lower than R-410A, making them far less harmful to the environment.
By mandating the switch, the EPA is pushing the HVAC industry to play its part in creating a more sustainable future. For businesses, this isn’t just about compliance—it’s about staying competitive in a marketplace that increasingly values environmental responsibility.
Impact on HVAC Manufacturers
Manufacturers are at the front lines of this transition. Switching refrigerants isn’t as simple as dropping a new chemical into an old design. Entire systems must be re-engineered to safely and efficiently handle the properties of A2L refrigerants.
-
Equipment redesign: Compressors, coils, and valves must be optimized for the pressures and flow characteristics of A2Ls.
-
Safety standards: Because A2Ls are classified as “mildly flammable,” manufacturers must add features like leak detectors, automatic shut-off systems, and ventilation safeguards.
-
Cost implications: Retooling production lines, testing new designs, and meeting regulatory standards all raise costs. Those increases are expected to filter down to the customer in the form of higher equipment prices.
For facilities, that means budgeting for HVAC upgrades is about to get more complex. Systems purchased in the coming years will carry higher upfront costs, but they’ll also offer opportunities for energy savings and regulatory compliance.
Impact on HVAC Technicians
Technicians are the backbone of system reliability, and their work is also changing with the refrigerant transition.
-
Training & certification: A2Ls require special handling due to their flammability and pressure differences. Technicians must complete updated training and certifications to safely install, maintain, and repair systems.
-
New tools & procedures: Servicing A2L systems often requires updated recovery machines, gauges, and leak detection equipment. Protocols for storage, transport, and charging systems are also changing.
-
Safety focus: Leak management and ventilation become even more critical when working with mildly flammable refrigerants.
At Hays Service, we’ve already invested in this training so our technicians can deliver the same reliability and safety standards our customers count on, no matter what refrigerant their system uses.
Impact on Facility Owners and Consumers
If you manage a building, the refrigerant shift will affect your bottom line in several ways:
-
Higher upfront costs
New HVAC systems designed for A2Ls are expected to be more expensive due to the redesigns and safety features required. -
Maintenance considerations
R-410A will remain available for servicing existing systems for a while, but as production phases out, the price will rise. That means maintaining older systems could get more expensive year after year. -
Energy efficiency benefits
The good news: A2L systems are engineered with efficiency in mind. Many businesses will see lower energy bills, which can offset some of the higher upfront costs over time. -
The importance of planning
If your HVAC system is approaching the end of its service life, planning your replacement now is wise. Waiting until failure could mean paying premium prices or scrambling to find available equipment.
For businesses, the refrigerant transition is less about “if” and more about “when.” A proactive approach will save both money and stress.
A Closer Look at R-454B and R-32
Not all A2Ls are the same. Two refrigerants are emerging as leading replacements for R-410A:
-
R-454B: With a GWP of about 466, it’s nearly 80% lower than R-410A. It’s quickly becoming the go-to choice for whole-building systems and is already being adopted by major manufacturers.
-
R-32: With a GWP around 675, R-32 is often used in ductless mini-split systems. It’s slightly more flammable than R-454B, but it offers excellent efficiency and is popular in smaller applications.
Knowing which refrigerant your system uses matters. It will determine not just your equipment costs but also your technician’s service approach and long-term operating expenses.
Preparing Your Business for the Transition
The refrigerant shift isn’t just a technical change—it’s a business decision. Here are practical steps to take now:
-
Assess your current equipment
How old is your HVAC system? If it’s nearing the end of its expected life (10–15 years for most systems), now is the time to start planning. -
Factor future refrigerant costs
Maintaining an older R-410A system may look cheaper upfront, but rising refrigerant prices could change that math quickly. -
Budget for replacements
Because new equipment will be more expensive, building a replacement plan into your capital budget now will help you avoid sticker shock later. -
Prioritize technician expertise
Not every service provider is equally prepared for the A2L transition. Make sure your HVAC partner has invested in training and tools for handling the new refrigerants. -
Think efficiency
Look beyond the upfront cost. Factor in the potential energy savings of new systems, especially if you operate in a facility with high HVAC loads.
By treating the refrigerant shift as part of your long-term facility strategy, you can turn a regulatory requirement into an opportunity for savings, reliability, and sustainability.
The Bottom Line
The move away from R-410A is one of the most significant changes the HVAC industry has seen in decades. It affects equipment design, technician training, safety standards, costs, and long-term maintenance strategies.
For businesses, the key is preparation. Understand what’s changing, plan ahead for system replacements, and partner with a service provider that’s ready for the future. At Hays Service, we’re committed to helping our customers navigate this transition smoothly. Our technicians are trained, our strategies are proactive, and our focus remains where it always has been: keeping your facility comfortable, efficient, and compliant.
Change can be disruptive, but it can also be an opportunity. With the right planning, the refrigerant transition can position your business for greater efficiency and sustainability in the years ahead.
