Refrigerant updates are nothing new in the HVAC world, but the transition to R-454B marks one of the most significant changes in recent years. As of January 1, 2025, newly manufactured residential and light commercial HVAC systems must use low Global Warming Potential (GWP) refrigerants like R-454B instead of the once popular R-410A. This change is part of a broader effort to reduce the carbon footprint of heating and cooling systems nationwide while improving their energy efficiency.
If you’re a homeowner or business owner in the greater Dallas area, understanding how this shift impacts your HVAC system is important. Whether you’re maintaining an existing system or considering a replacement, TemperaturePro Dallas is here to help you navigate this new chapter in HVAC technology.

Why the Change to R-454B?
The transition to R-454B is driven by new regulations from the Environmental Protection Agency (EPA) under the American Innovation and Manufacturing (AIM) Act. These regulations phase out high Global Warming Potential (GWP) refrigerants.
The EPA now requires the industry to adopt low-GWP refrigerants such as R-454B, an A2L refrigerant with a significantly reduced environmental impact. As of 2025, all newly manufactured HVAC equipment must use approved low-GWP refrigerants. This change follows the earlier shift from previous refrigerants like R-22, reflecting the HVAC industry's ongoing commitment to reducing its carbon footprint and protecting the ozone layer.
What HVAC Systems Are Affected?
The refrigerant change impacts a wide range of HVAC systems, including:
- Central air conditioners
- Heat pumps
- Ductless mini-splits
- Packaged systems
- Rooftop units
If your system relies on refrigerants to cool or heat your space, this regulation applies. HVAC manufacturers are now producing new equipment optimized for R-454B and other low-toxicity refrigerants.
Meet R-454B: The New Standard
R-454B is a next-generation refrigerant designed with efficiency and environmental responsibility in mind. It combines hydrofluoroolefin (HFO) and hydrofluorocarbon (HFC) compounds to deliver reliable performance while minimizing environmental impact.
Here are a few main benefits of R-454B:
- Environmentally Friendly: With a lower environmental impact than R-410A, R-454B significantly reduces greenhouse gas emissions and supports global climate goals.
- Energy Efficiency: Systems using R-454B are designed to operate more efficiently, helping reduce your energy bills over time.
- Future-Ready: New systems with R-454B ensure compliance with current and future regulations, offering peace of mind for years to come.
By investing in R-454B-compatible systems, you’re choosing a refrigerant that aligns with sustainability and modern HVAC standards.
What The R-454B Refrigerant Change Means for You
If your existing HVAC system uses R-410A, don’t worry—it’s still safe and effective. R-410A will continue to be available for maintenance and repairs until 2040, but its production is being reduced. As a result, costs for R-410A may rise over time, making the upkeep of older systems more expensive.
If you’re planning to replace your air conditioning system, heat pump, or mini-split this year, choosing one designed for R-454B is a smart move. New systems are optimized for this refrigerant, meaning they’ll have better efficiency and long-term compatibility with the evolving regulations.
