Industry Expert Quote: Nick Arch, Vice President at Carrier, states, “We continue to lead the industry by offering R-454B systems ahead of the 2025 regulatory changes, ensuring that our customers have access to sustainable, efficient HVAC solutions.”
What is R454B Refrigerant?
As the HVAC industry shifts toward more environmentally friendly solutions, this new refrigerant is emerging as a game-changer. Designed to replace older refrigerants like R-410A, it offers a significantly lower Global Warming Potential (GWP), making it a more sustainable choice for cooling systems.
Understanding Hydrofluoroolefins (HFOs) and Their Benefits
R-454B belongs to the hydrofluoroolefins (HFO) family, a type of refrigerant explicitly developed to minimize environmental impact.
Unlike traditional refrigerants, HFOs have lower toxicity and global warming potential, reducing the strain on our climate. This new HFO technology aligns with the HVAC industry’s push toward sustainability, ensuring efficient cooling with a fraction of the environmental footprint.
Below, we explore R-454 B, why it’s replacing R-410A, and how it benefits the environment and homeowners in our community.
Why is R-454B Refrigerant Important?
This refrigerant has a GWP of 466, which is 78% lower than the widely used R-410A refrigerant, making it a more environmentally friendly option. With regulations from the Environmental Protection Agency (EPA) tightening, the HVAC industry is transitioning to refrigerants with lower GWP to reduce climate change impacts.
The move to this new refrigerant aligns with these efforts and helps HVAC systems comply with upcoming 2025 phase-out regulations for R-410A.
EPA’s Refrigerant Transition Goals
The EPA has initiated this refrigerant transition as part of a broader effort to phase out high-GWP substances across various industries.
By 2025, HVAC systems using R-410A will no longer be compliant with new systems sold in the U.S., highlighting R-454B as a vital choice to meet regulatory and sustainability goals.
How Does R-454B Work and Why Is It Better?
It's part of the hydrofluoroolefins (HFOs) family, designed to provide efficient cooling while reducing its impact on global warming.
This refrigerant performs similarly to R-410A in terms of cooling but requires less energy, leading to potential savings on your utility bills over time.
Its low Global Warming Potential (GWP) makes it a more environmentally responsible choice.
With minor adjustments, it is compatible with many current HVAC systems, making the transition easier for homeowners and businesses.
Technical Specifications and Cooling Performance
It offers robust cooling performance with increased thermal stability, ensuring reliable operation even in extreme temperatures. Its A2L safety rating indicates mild flammability, but it’s considered safe under proper handling and maintenance conditions. Its energy-efficient design makes it a cost-effective option for homeowners and businesses.
R-454B vs. R-410A: What's the Difference?
- Global Warming Potential (GWP): R-454B has a GWP of 466, compared to R-410A's GWP of 2088, making it a more sustainable choice.
- Energy Use: R-454B is generally more energy-efficient, so cooling systems using this refrigerant are likely to be more cost-effective over time.
- EPA Regulations: R-454B complies with upcoming EPA regulations, while R-410A will be phased out for use in new systems starting in 2025.
Should You Upgrade Your HVAC System?
If your current HVAC system uses R-410A or even R-22, upgrading to a new system with R-454B refrigerant can provide long-term benefits. At Crystal Heating & Cooling, we’re here to help you navigate this change. Schedule a service call today, and our team will assess your current system.
What About R-22 Systems?
Some homeowners still use older HVAC systems that rely on R-22 refrigerant, which was phased out in 2020. If you're still using R-22, the switch to R-454B may be even more beneficial, as continuing to use R-22 will likely become increasingly expensive.
