As the HVAC industry heads toward a significant milestone with the 2025 refrigerant transition, both companies and customers need to prepare for impactful changes. In an effort to comply with environmental standards, the industry is phasing out older refrigerants and introducing new options with lower environmental impact. Here, we’ll explore what this transition means, the key refrigerant changes, and how it will affect HVAC professionals and consumers alike.
Why the 2025 Refrigerant Transition?
The HVAC industry is moving toward more sustainable solutions to meet global environmental standards. The 2025 refrigerant transition is primarily driven by the need to reduce greenhouse gas emissions and the environmental impact of hydrofluorocarbons (HFCs) commonly used in refrigerants. One of the major contributors to climate change, HFCs have a high global warming potential (GWP) which accelerates climate change by trapping heat in the atmosphere.
In the U.S., the Environmental Protection Agency (EPA) has been working in alignment with these goals by implementing the American Innovation and Manufacturing (AIM) Act, which sets guidelines and deadlines for phasing out high-GWP refrigerants. With 2025 as the target date, new HVAC equipment will need to comply by using refrigerants with a significantly lower GWP.
What Refrigerants are Being Phased Out?
The refrigerant R-410A has been the industry standard in most residential and commercial HVAC systems over the past two decades. However, with a GWP of 2,088, it is now among the refrigerants scheduled to be phased out. The EPA is requiring a switch to refrigerants with a GWP of 750 or lower, prompting the HVAC industry to introduce new alternatives that can meet these standards while still providing effective heating and cooling performance.
Older refrigerants such as R-22, once a common choice for air conditioning systems, were already banned from production and import in the U.S. back in 2020 due to its harmful impact on the ozone layer. This next step with R-410A represents another leap forward in environmentally responsible refrigeration practices.
New Refrigerants on the Horizon
With the phaseout of R-410A, two new refrigerants are expected to become the main alternatives for residential and light commercial HVAC systems:
R-454B: With a GWP of around 467, R-454B is one of the promising alternatives. It is a blend of two refrigerants and offers comparable performance to R-410A, making it a viable replacement in new systems.
R-32: This refrigerant, with a GWP of 675, is already widely used in Europe and parts of Asia. R-32 is valued for its energy efficiency and has a similar cooling capacity to R-410A, allowing manufacturers to easily adapt equipment for this replacement.
Both R-454B and R-32 are classified as mildly flammable, which means they need to be handled with additional care, particularly in servicing and maintenance. However, with proper training and safety protocols, the industry has confidence in safely managing these new refrigerants.
What the Transition Means for HVAC Technicians and Contractors
The 2025 refrigerant transition requires a shift in knowledge and safety procedures for HVAC technicians and contractors. Working with mildly flammable refrigerants introduces a new set of safety and handling standards. Here are key areas where HVAC professionals will be impacted:
Certification and Training: Technicians will need additional training to handle mildly flammable refrigerants like R-454B and R-32. This will include updated EPA 608 certification and practical safety training to ensure proper handling, storage, and servicing of equipment containing these new refrigerants.
Safety Standards and Equipment: New standards and procedures will need to be observed when installing and servicing systems with mildly flammable refrigerants. This may also mean an investment in new tools and equipment specifically designed for handling these refrigerants.
Service Protocols for Legacy Systems: As new systems with R-454B and R-32 become standard, technicians will still need to support existing systems that use R-410A. This will require ongoing knowledge of older systems and refrigerants, along with careful management of refrigerant supplies as production of high-GWP refrigerants decreases.
Adaptation and Upgrading Equipment: HVAC contractors and companies will need to adjust their installation and maintenance strategies to align with these refrigerant changes. New system designs and configurations may require updated techniques in sizing, pressure management, and leak detection.
What the Transition Means for Consumers
For homeowners and business owners, the 2025 refrigerant transition brings both benefits and potential changes in how HVAC systems are purchased and maintained.
Increased Efficiency and Environmental Benefits: Systems that use R-454B and R-32 are designed to have lower environmental impact and, in many cases, improved energy efficiency. Over time, this shift can lead to lower energy bills and a reduced carbon footprint for end users.
Changes in System Costs: New systems designed to run on R-454B or R-32 may have slightly higher upfront costs, as manufacturers work to incorporate the latest technology. However, these systems are also expected to offer long-term savings through energy efficiency. As production of R-410A declines, older systems will become more expensive to repair and maintain, encouraging more consumers to upgrade to environmentally-friendly systems.
Maintenance and Repair Considerations: The cost of maintaining an R-410A system may increase over time as refrigerant supplies decrease. Homeowners with R-410A systems should consider either a refrigerant retrofit or an upgrade to a new system within the next few years. Additionally, consumers should seek out contractors and technicians who are trained and certified to handle the new refrigerants, ensuring both safety and system reliability.
Tips for Navigating the Transition
For HVAC businesses, contractors, and consumers alike, the following tips can help ensure a smooth transition to the new refrigerant standards:
Start Planning Early: Businesses should anticipate the costs of training, equipment upgrades, and new safety protocols. Early planning can help ensure a seamless transition to the new refrigerants by 2025.
Inform and Educate Customers: HVAC professionals should take the time to educate customers about the benefits of new refrigerants and why the change is necessary. Helping customers understand the environmental impact of refrigerants and the long-term cost benefits of new systems can make this transition smoother.
Stay Updated on Regulations: Regulations on refrigerants are likely to continue evolving. Staying informed about local and federal requirements is essential for HVAC businesses to ensure compliance and avoid penalties.
Invest in Employee Training: Training on handling mildly flammable refrigerants is crucial. Regular training sessions and updated certifications can prepare technicians to handle new refrigerants safely and professionally.
Be Transparent with Customers about Cost Implications: New refrigerants may involve initial price adjustments for consumers. However, focusing on the energy savings and environmental benefits over the lifetime of the equipment can help to offset any immediate cost concerns.
