Understanding R-410A Refrigerant
Welcome to our comprehensive guide on R-410A refrigerant. R-410A refrigerant is a refrigerant that was widely used in HVAC systems between 2010 and 2023. However, due to its high global warming potential (GWP), R-410A refrigerant is being phased out. In response to environmental concerns, new alternative such as R-454B refrigerant, also known as Puron Advance™, are being introduced that offer similar performance with lower environmental impacts.
What is R-410A Refrigerant?
R-410A refrigerant was a commonly used refrigerant in air conditioning systems between 2010 and 2023. It is a blend of two hydrofluorocarbon (HFC) components: difluoromethane (R-32) and pentafluoroethane (R-125). R-410A was introduced as a more environmentally friendly alternative to older refrigerants like R-22 refrigerant.
At the time of its release, one of the primary advantages of R-410A refrigerant was its higher energy efficiency. It has a higher heat transfer coefficient, which allows it to absorb and release heat more effectively, resulting in improved cooling performance and reduced energy consumption. R-410A refrigerant is also non-ozone depleting, meaning it does not contribute to the depletion of the ozone layer.
Why R-410A Is Being Phased Out
R-410A refrigerant is being phased out due to environmental concerns and regulatory measures from to its impact on global warming.
R-410A is classified as a hydrofluorocarbon (HFC) and has a lower ozone depletion potential compared to older refrigerants like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). However, R-410A is a potent greenhouse gas, with a high global warming potential (GWP). Greenhouse gases trap heat in the Earth's atmosphere, contributing to global warming and climate change.
In response to these concerns, Carrier products in 2024 and beyond are using a more eco-friendly alternative to R-410A, known as Puron Advance or R-454B. This new non-ozone depleting refrigerant provides efficient cooling while minimizing environmental impact with a low global warming potential . Manufacturers, including Carrier, are committed to developing and promoting sustainable solutions that comply with environmental regulations and meet consumer demands.

Frequently Asked Questions About R-410A Refrigerant
Yes, R-410A refrigerant is being phased out due to its high global warming potential (GWP). The U.S. EPA has mandated a transition to lower-GWP refrigerants under the AIM Act, with production and import restrictions starting in 2023 and further reductions by 2028. While R-410A systems can still be used and serviced, new systems will increasingly adopt eco-friendlier refrigerants to comply with environmental regulations.
Individuals can only buy R-410A refrigerant if they have an EPA Section 608 certification. This certification ensures the buyer is trained in handling refrigerants safely and legally. Without certification, purchasing R-410A is prohibited under federal law. Homeowners needing refrigerant for their HVAC systems must hire a licensed HVAC professional. As R-410A is being phased out, consider upgrading to a system using newer, eco-friendly refrigerants to avoid future availability and cost issues.
R-454B is the primary refrigerant replacing R-410A. It has a significantly lower global warming potential (GWP), making it more environmentally friendly.
