The R-410A phase-out is part of a global effort to reduce the use of high-GWP (Global Warming Potential) refrigerants, which contribute to climate change.
With over 40 years of experience serving the Greater St. Louis area, Crystal Heating & Cooling is here to help you navigate the R-410A phase-out and understand how it impacts your HVAC system, energy costs, and the environment. Our expert team is ready to clarify what this means for your HVAC system and how you can plan to ensure compliance, efficiency, and sustainability.
We back this information with insights from industry experts and environmental authorities, which will help you navigate your options as we move toward more sustainable solutions for St. Louis homeowners and commercial business owners.
Understanding the 410A Phase-Out
As the HVAC industry moves toward more environmentally friendly solutions, the phase-out of R-410A refrigerant marks a significant step. In 2025, manufacturers will no longer use R-410A in new HVAC systems. Instead, systems will transition to next-generation refrigerants with a lower environmental impact, such as R-454B.
If you live in Greater St. Louis, this change may affect your future HVAC decisions. Understanding your options now can help you prepare for a smooth transition.
Impact on St. Louis Homeowners
For homeowners in Greater St. Louis, this R-410A refrigerant phase-out means any new HVAC system installed after 2025 will use a next-generation refrigerant like R-454B. This switch aligns with environmental goals and can lower energy costs over time.
Planning can help you comply with regulations, reduce your carbon footprint, and ensure your home stays comfortable and efficient.
What’s Replacing R-410A?
One of the key replacements for R-410A is R-454B, which Carrier chose for its next generation of air conditioners and heat pumps. This new refrigerant has a Global Warming Potential (GWP) of 466—75% lower than R-410A.
Carrier is committed to leading the charge in sustainability with our shift to Puron Advance (R-454B), ensuring we meet and exceed future environmental regulations.” – Nick Arch, VP of Residential HVAC Solutions, Carrier
While existing HVAC systems using R-410A will continue to be serviceable, new installations after 2025 will require systems designed for lower-GWP refrigerants like R-454B and R-32 to meet environmental regulations. This means R-454B contributes significantly less to climate change while providing efficient cooling and heating for residential and commercial systems.
Why Is R-410A Being Phased Out?
The Environmental Protection Agency (EPA) has set limits on refrigerants with high GWPs to reduce their impact on global warming. R-410A has a GWP of 2088, which far exceeds the upcoming 700 GWP limit that will take effect in 2025.
Transitioning to refrigerants like R-454B ensures HVAC systems remain effective while minimizing their environmental impact.
EPA Goals for Environmental Compliance
The EPA’s 2025 refrigerant goals are part of a phased approach to reduce high-GWP substances nationwide. Future HVAC systems will align with national standards for Greater St. Louis homeowners, helping you support a greener St. Louis.
Will This Affect My Current HVAC System?
If your HVAC system uses R-410A, you don’t need to replace it immediately.
While production of R-410A will eventually stop, it will still be available for repairs and maintenance until at least the early 2030s. However, as availability decreases, costs may rise.
For homeowners planning to upgrade their system in Greater St. Louis after 2025, it will likely use one of the newer refrigerants like R454B.
How Long Will R-410A Be Available for Repairs?
In St. Louis, HVAC professionals expect R-410A to remain available for repairs for several years. Transitioning to R-454B sooner can help you avoid future price increases and take advantage of new energy-efficient systems.
How Does the Change Impact HVAC Prices?
The shift to R-454B and other refrigerants may slightly increase the upfront cost of HVAC systems due to newer technology. However, these systems are generally more energy-efficient, helping lower utility bills in the long run.
“The transition from high-GWP refrigerants like R-410A to lower-GWP alternatives is crucial for mitigating climate change and ensuring a more sustainable future.” – Environmental Protection Agency (EPA)
Comparison of R-410A vs. R-454B Refrigerants
As the HVAC industry moves toward sustainable refrigerants, it’s essential to understand the differences between R-410A and R-454B. Below is a quick comparison of these two refrigerants, highlighting environmental impact, energy efficiency, and compatibility with existing systems.
| Feature | R-410A | R-454B | Notes |
|---|---|---|---|
| Global Warming Potential (GWP) | 2088 | 466 | Lower GWP means R-454B is more eco-friendly |
| EPA Compliance for New Systems | Phased Out After 2025 | Compliant | R-454B meets 2025 EPA regulations |
| Energy Efficiency | Moderate | High | R-454B is more energy-efficient |
| Compatibility with Existing Systems | Limited, needs retrofit | Limited, requires a compatible system | Consult with an HVAC professional |
| Availability | Declining after 2025 | Increasing | R-454B will be widely available |
| Cost for Replacement/Repair | Potentially higher in the future | Stable | R-410A prices may rise as production decreases |
What Are The Top 3 Options For Moving Forward?
If your HVAC system uses R-410A, you don’t need to panic. While the refrigerant will be phased out for new systems, replacing your entire unit is unnecessary. However, it’s a good idea to plan and explore your options.
Here are three options to consider:
- Schedule a Service Call with an HVAC Pro: Have a licensed HVAC professional inspect your current system to see if it can support the new R-454B refrigerant. Some systems may be compatible with minor adjustments, while others may need upgrades to handle the new refrigerant.
- Upgrade to a New System: If your HVAC system is older or nearing the end of its lifespan, upgrading to a newer, energy-efficient system using R-454B might save you money in the long run. Newer systems will comply with environmental regulations and are often more efficient, leading to lower energy bills.
- Consider Your Budget: Remember that the cost of R-410A may rise over time as it becomes less available. By switching to a new system, you can avoid higher repair costs and take advantage of rebates or financing options for energy-efficient upgrades.
Switching to an R-454B system will ensure compliance with EPA regulations and significantly reduce your carbon footprint by using a refrigerant with a much lower Global Warming Potential (GWP).
What About R-22?
The R-410A phase-out follows the earlier R-22 phase-out, which ended production in 2020. If your system still uses R-22, now is an excellent time to upgrade to a modern refrigerant like R-454B to save on maintenance costs and meet environmental standards.
Using R-22 can be costly, as the refrigerant is no longer produced and has significantly increased in price. Upgrading to a system that uses R-410A or the newer R-454B ensures compliance with environmental regulations and lowers future maintenance costs.
