Although the R-410A refrigerant is more environmentally friendly than R-22, it still contributes to global warming if released into the atmosphere — which is why it’s being discontinued
What is R-410A?
R-410A is a hydrofluorocarbon (HFC) refrigerant commonly used in residential and commercial air conditioning systems. It replaced older refrigerants like R-22, which have been phased out due to their harmful environmental effects. R-410A has become a standard refrigerant for modern HVAC systems. That is until 2025.
Why is R-401A Being Discontinued?
R-410A is being phased out due to its high global warming potential (GWP) and environmental regulations aimed at reducing the impact of refrigerants on climate change. While it is ozone-friendly and does not harm the ozone layer like its predecessor R-22, R-410A contributes significantly to global warming if released into the atmosphere.
High Global Warming Potential (GWP)
The GWP of R-410A is approximately 2,088, meaning it has 2,088 times the warming effect of carbon dioxide over 100 years.2 This makes it unsuitable for long-term so we can reduce greenhouse gas emissions.
The U.S. Environmental Protection Agency (EPA) has introduced policies under the American Innovation and Manufacturing (AIM) Act3 to phase down HFC production and consumption. Many countries are adopting similar measures to combat climate change, pushing for lower-GWP refrigerants.

What is Replacing R-401A?
New refrigerants with significantly lower GWP are being developed and introduced as replacements for R-410A. Some of the examples of lower carbon footprint refrigerants include:
● R-32: A single-component refrigerant with a GWP of 675, much lower than R-410A.
● R-454B (Opteon™ XL41): A blend with a GWP of 466, currently being adopted in new HVAC systems.
● R-466A: A non-flammable, low-GWP alternative gaining traction in the industry.
How Will the Discontinuation of R-401A Impact the HVAC Industry?
The discontinuation of R-410A will significantly impact the HVAC industry by driving changes in system design, installation practices, technician training at RSI, and certifications like the EPA Section 608 certification.
Impact on HVAC Businesses
Retooling production lines and updating equipment to handle new refrigerants will require significant investment. However, companies focusing on eco-friendly and efficient technologies may gain a competitive edge.
Effects on Existing HVAC Systems
As R-410A production decreases, its cost is expected to rise, making it expensive to service older systems. Also, homeowners and businesses may need to retrofit or replace systems that are not compatible with new refrigerants. This will increase the demand for HVAC technicians that are well versed in R-401A refrigerant and the retrofitting of HVAC systems. Plus, HVAC technicians will still service existing R-410A systems for years to come, ensuring a gradual transition rather than an abrupt shift.
Increased Training Requirements
Working with new refrigerants like R-32 and R-454B requires specialized training due to differences in handling, flammability, and pressures. HVAC technicians will need updated certifications, such as EPA Section 608 and manufacturer-specific qualifications. The curriculum at RSI will also adopt this specialized training and introduce it into the HVAC program.
Consumer Impact
New systems designed for low-GWP refrigerants may have higher initial costs due to advanced technology and R&D investments. Incentives and rebates from governments and utility companies may offset these costs.
Modern systems using low-GWP refrigerants are often more energy-efficient, leading to lower utility bills over time. Eco-conscious consumers may prioritize systems with sustainable refrigerants.
Environmental and Regulatory Impact
The transition supports global efforts under the Kigali Amendment4 to phase down HFCs and reduce greenhouse gas emissions. HVAC companies that adapt quickly will comply with these regulations and avoid penalties.
Adoption of low-GWP refrigerants will reduce the industry’s carbon footprint, contributing to climate change mitigation.
Opportunities for the HVAC Industry
Training programs, like the one at RSI will update curriculum for new refrigerants creating opportunities for graduates to stay ahead of the learning curve. Businesses that align with sustainability goals can enhance their reputation and attract eco-conscious clients. Plus, transitioning older systems to new refrigerants or replacing them will generate revenue for HVAC technicians.
