With evolving environmental standards and refrigerant regulations, the HVAC industry is undergoing a major transition toward more eco-friendly refrigerants. At Flex Distribution, we stay at the forefront of these changes to support our partners and clients through this transformation. Here’s everything you need to know about the transition from R410A to alternatives like R32 and R454B.
Why Are Refrigerants Changing?
R410A, widely used in air conditioning and heating systems, is being phased out due to its high Global Warming Potential (GWP). With a GWP of approximately 2,088, this refrigerant significantly contributes to climate change when leaked.
Governments and international organizations, including the Kigali Amendment, have set reduction targets for high-GWP refrigerants. As a result, R410A will gradually be banned in favor of more environmentally friendly alternatives.
The Alternatives: R32 and R454B
1. R32: A Promising Option
R32 is already being used in some modern systems. Its advantages include:
- Lower GWP: Approximately 675, which is three times lower than R410A.
- Improved energy efficiency.
- Similar handling to R410A, though it is slightly flammable (A2L classification).
However, R32 is not compatible with existing R410A systems, requiring a complete system upgrade.
2. R454B: A Hybrid Alternative
- Even lower GWP than R32, around 466.
- Less flammable than R32 (still classified as A2L).
- Compatible with system designs similar to R410A, making the transition easier.
Regulatory Changes in Canada and the U.S.
In Canada:
- Production and import: Canada is gradually reducing HFC production and importation, including R410A, in line with the Kigali Amendment to the Montreal Protocol. While reductions have already started, a complete phase-out is expected by 2028 (Federal Gazette).
- Use in new equipment: Canadian regulations prohibit certain HFCs in new refrigeration and air conditioning equipment. However, specific nationwide phase-out dates for R410A in residential and commercial systems have not yet been established.
- Maintenance of existing systems: The use of R410A for servicing existing systems is still allowed.
In the United States:
- Production and import: The U.S. Environmental Protection Agency (EPA) has proposed rules banning R410A in new residential air conditioners and heat pumps starting January 1, 2025. Equipment manufactured before this date can still be installed until stock runs out.
- Maintenance of existing systems: R410A can still be used for servicing existing systems. However, its phased reduction may lead to higher costs and limited availability over time.
How Flex Distribution Can Help
At Flex Distribution, we understand that this transition may raise concerns among our contractor clients. That’s why we are committed to guiding you through this process in a smooth and reassuring way.
- Gradual product updates: We are actively integrating new equipment compatible with R32 and R454B. This update will be rolled out in stages, giving you ample time to adapt to the new standards.
- Training and technical support: We offer training sessions to familiarize you with the features and safe handling of the new refrigerants. Our technical team is also available to answer your questions and assist with installation and maintenance.
- Regulatory monitoring: We stay informed about regulatory changes to provide you with accurate and up-to-date information, helping you plan your business activities with confidence.
While upcoming changes are significant, there is still plenty of time to prepare, especially in Canada, where some restrictions will only take effect from 2028. We are committed to making this transition as seamless as possible, ensuring you have the resources and support needed to succeed.
