Legacy Air’s Guide to the 2025 R-410A Refrigerant Transition

Legacy Air Conditioning Services in Las Vegas and Reno

As of January 1, 2025, the HVAC industry is undergoing a significant change: the phase-out of R-410A refrigerant in new air conditioning and heat pump systems. This shift, mandated by the Environmental Protection Agency (EPA) under the American Innovation and Manufacturing (AIM) Act, aims to reduce the environmental impact of refrigerants with high global warming potential (GWP).

What Is R-410A and Why Is It Being Phased Out?

R-410A has been the standard refrigerant in HVAC systems since the early 2010s. While it replaced the ozone-depleting R-22, R-410A still has a high GWP of 2,088, contributing to climate change if released into the atmosphere. To mitigate this, the EPA is transitioning to refrigerants with lower GWPs, such as R-454B and R-32, which are classified as A2L refrigerants—mildly flammable but safe for residential use when properly installed and maintained.

What This Means for Your Legacy Air System

  • Existing Systems: If your HVAC system uses R-410A and is still functioning well, you can continue to operate and maintain it. R-410A will remain available for servicing existing systems for the foreseeable future.

  • Repairs and Maintenance: As R-410A becomes less prevalent, parts and refrigerant may become more expensive. It’s advisable to plan for potential future costs associated with maintaining older systems.

  • Upgrading Your System: If your system is nearing the end of its lifespan or requires significant repairs, consider upgrading to a new system that uses R-454B or R-32 refrigerant. These systems are more energy-efficient and environmentally friendly.

Should You Replace Your System Now?

Upgrading before the end of 2025 can offer several benefits:

  • Cost Savings: New systems using R-454B or R-32 refrigerants may be more expensive upfront but can lead to long-term savings through improved energy efficiency.

  • Availability: Purchasing a new system now ensures you can select from a wider range of models and avoid potential supply shortages as manufacturers transition to new refrigerants.

  • Environmental Impact: By upgrading, you contribute to reducing the environmental footprint of your home.

Frequently Asked Questions

What is the R-410A refrigerant phase-out, and why is it happening?

The R-410A refrigerant phase-out is part of a federal initiative under the EPA’s AIM Act, which aims to reduce the environmental impact of high-global-warming-potential (GWP) refrigerants. R-410A, while effective, has a GWP of 2,088, contributing significantly to climate change. The phase-out is a move towards adopting refrigerants with lower GWPs, such as R-454B and R-32, which are more environmentally friendly.

How will the refrigerant phase-out affect my current HVAC system?

If your HVAC system currently uses R-410A, you can continue using it as normal, and it will still be available for servicing. However, as the refrigerant becomes less available, repairs and replacements may become more expensive. If your system is aging, it may be a good time to consider upgrading to a system using a refrigerant with a lower GWP.

Should I replace my HVAC system before 2025?

Upgrading your system before 2025 can be beneficial. New systems with lower-GWP refrigerants are more energy-efficient and may reduce your long-term utility costs. Additionally, purchasing before the deadline ensures better availability of units and components. However, if your current system is still performing well and doesn’t require costly repairs, you may choose to wait.

What are the new refrigerants that will replace R-410A?

The two primary refrigerants replacing R-410A are R-454B and R-32. These refrigerants have a significantly lower global warming potential (GWP) than R-410A, making them more environmentally friendly while still providing efficient cooling and heating. These refrigerants are expected to be standard in all new HVAC systems starting in 2025.

Can I still get my HVAC system serviced if it uses R-410A refrigerant?

Yes, your HVAC system can still be serviced if it uses R-410A refrigerant. The phase-out only applies to the production of new systems and refrigerant, not to the servicing of existing systems. However, as R-410A becomes less available, parts and servicing may become more expensive, so it’s important to plan ahead for potential repairs.

How can Legacy Air help me with the refrigerant transition?

Legacy Air offers expert consultations to evaluate your HVAC system, ensuring it continues to perform efficiently. If it’s time to upgrade, we can install a new system with a refrigerant that complies with the latest environmental standards. Our team can also help with regular maintenance to keep your current system running smoothly until you’re ready to make the change.
