Understanding the R410 Refrigerant Phase-Out

Apr 25, 2024 | Blog

The phase-out of R410 refrigerant is an important step in protecting the environment, but what does it mean for homeowners and HVAC users? Let’s break down the key points!

The Transition Timeline

R410 refrigerant is being phased out gradually starting in 2025. The phase-out of R410 refrigerant is part of a broader effort to reduce the use of hydrofluorocarbons (HFCs), which are known to contribute to the depletion of the ozone layer. R22, another common refrigerant, was phased out in January 2020, following a process that began in 2014-2015. The production of R22 dropped significantly in 2019, leading to a complete stoppage on January 1, 2020.

Why the Change?

R410 contains HFCs which can contribute to ozone depletion. To address this, the American Innovation & Manufacturing Act was passed in 2020, giving the EPA the authority to set stricter standards for HFC use. This led to a plan released in September 2021 to reduce HFC consumption, including phasing out R410 in HVAC systems starting in 2025.

What’s Next?

While R410 is being phased out, HVAC systems will transition to using A2L refrigerants like R32 and R454B. These refrigerants are considered more environmentally friendly, although they require some changes to HVAC systems to ensure safety and compliance. Air & Energy will continue to work with R410 and A2L refrigerants during the transition period.

How Does This Affect You?

For consumers, this means that as HVAC systems are upgraded or replaced, they will use the new, more sustainable refrigerants. There may be some additional costs associated with retrofitting older systems, but these changes are designed to benefit the environment in the long run. The phase out will be gradual, with most HVAC companies continuing to work with units of all refrigerant types.


With the phase-out of R410 refrigerant is a significant change, it is part of a broader effort to protect the environment. By understanding the reasons behind the transition and what to expect in the coming years, consumers can be better prepared for these changes in the HVAC industry.
