Guide to The R-410A Phase Out

As your reliable heating, cooling, and air conditioning partner, Anderson Air understands the crucial impact of recent changes in the HVAC landscape. One such change is the phase out of the R-410A refrigerant, a staple in air conditioning systems across the globe. 

In our commitment to keep you informed and help you make the best decisions for your home comfort needs, we’ve crafted this reader-friendly guide. You’ll learn about why this phase out is happening, what it means for you, and the next steps you should consider. 

Remember, we’re here to help you navigate these changes and ensure your home’s comfort isn’t compromised.

What is refrigerant, and what is R-410A?

Refrigerant is simply a chemical coolant that absorbs and releases heat during heat exchange. It’s integral to cooling and heat transfer systems like ACs and heat pumps. 

R-410A is a type of refrigerant commonly used in air conditioning systems today. This refrigerant is known for its efficiency and performance, making it the standard for various air conditioning systems in homes and businesses worldwide. It replaced R-22 (Freon), which was banned from HVAC systems in 2010. 

R-410A is a blend of hydrofluorocarbons (HFCs) — chemicals used for cooling — that don’t deplete the ozone layer but still contribute to global warming. 

Why is it being phased out?

Despite being ozone-friendly, this refrigerant is unfortunately a greenhouse gas with a GWP (Global Warming Potential) of 2088. This means it traps heat in the atmosphere 2088 times better than carbon dioxide – that’s like having insulating clouds! 

This high GWP rating is the driving force behind the phase out, as efforts to combat climate change intensify. 

Additionally, R-410A requires a much higher pressure to operate, putting more stress on HVAC components and increasing the likelihood of leaks that harm the environment. Phasing it out also acts as a preventative measure against hazardous refrigerant leaks

The government and climate experts agree that when it comes to our ecosystem, it’s best to play it on the safe side. 

When will the phase out come into effect, and what will replace it?

The year 2023 brought several shifts and changes, including many in the HVAC industry. 

Once a common solution to R-22, the EPA had originally hoped to ban it January 1, 2023, but that wasn’t possible. The current plan is to ban the use of R-410A in new AC units and heat pumps by January 1, 2025. It will be replaced by A2L refrigerants (another group of refrigerants with a much lower GWP and better efficiency). 

These refrigerants include: 

  • R-32
  • R-434B
  • R-452A
  • R-454A
  • R-454C
  • R-457A

It is important to note that the new A2L refrigerants cannot be used in existing R-410A units but only in units designed for them.

For US homeowners and business property owners, these changes may seem daunting. However, it’s essential to remember that this does not mean your air conditioning systems will suddenly become obsolete or illegal. If your current unit uses R-410A, you can still use your existing system without replacing it

Existing units will continue to be serviced and maintained with R-410A until its stock runs out. This phase out is aimed more at future installations and the overall goal of reducing our environmental impact. 

Interestingly enough, A2L refrigerant systems aren’t all that new. Around the world, many countries, like Australia and Japan, have already adopted this new type of refrigerant system – here in the US, we’re just arriving a little late to the party. Better late than never, though! 

It’s good for American homeowners and business proprietors to understand these regulations and take necessary actions to comply. If you are curious about specific regulations in Arkansas, contact our office for more information.

Transitioning to newer, more sustainable HVAC systems isn’t just about adhering to regulations—it’s also a step towards creating a healthier environment.

What should I do to prepare? Will my system be affected? 

With all of these changes, you might be wondering, “Well, what now?” Fortunately, we’re not in the business of just throwing information at you with no explanation or next steps. In this section, we’ll look at what you can do to make sure you stay comfy and compliant. 

When it comes to their HVAC system, most people fall into three general categories. 

  • I don’t need a replacement. 
  • I need a replacement!
  • I’m not sure. 

Suppose you don’t need a replacement, either because you recently got your system replaced or your unit is still working well. In this case, you don’t have to worry about replacing your unit with a new A2L system. Professionals can still run regular maintenance, repairs and checks on R-410A systems. Since the phase out is gradual, spare parts will still be available for repairs. 

If you are in the market for a replacement unit or aren’t sure, contact HVAC professionals like the technicians on our team. 

Given the changes in refrigerant regulations, it’s an opportune time for homeowners to consider investing in an A2L refrigerant system. Transitioning to these new systems ensures compliance with the latest standards and holds long-term benefits in terms of energy efficiency and environmental impact.

If your system is older or utilizes R-410A, you may need to consider an upgrade due to the limited availability of this refrigerant. An upgrade is not just a compliance move; it can also boost the market value of your property. 

Modern HVAC systems are more energy-efficient, reducing energy costs and contributing to a greener environment, which are attractive features for potential buyers.

As you navigate this transition, professional guidance is key. HVAC professionals are well-versed in both the regulatory landscape and the latest technologies and can provide valuable advice on system compatibility, installation, and cost-effectiveness. 

Don’t hesitate to reach out to a trusted HVAC professional to discuss your options and decide on the best course of action. They can help you find a financing solution to benefit you in the long run. 


In conclusion, while the phase out of R-410A might seem inconvenient, it presents an opportunity for property owners to upgrade their systems, enhance property value, save on energy costs, and help protect the environment.
