What refrigerant will replace R-410A in 2025? For whole-home systems, Lennox has chosen 2025 Compliant Refrigerant
Air conditioner and heat pump manufacturers are rolling out new refrigerants to comply with EPA guidelines. Starting in January 2025, no new HVAC systems will use R-410A refrigerant. Instead, most residential systems will use either R-32 or R-454B refrigerant, both of which have a comparably lower environmental impact.
No. R-454B is NOT a drop-in replacement for R-410A. Although many of the characteristics of R-454B are similar to R-410A, the use of R-454B is restricted by code and regulation to systems for which it was specifically designed.
Yes. While 2025 compliant refrigerants have an A2L classification of mildly flammable, it poses no greater risk than common household products. In fact, there is a good chance that you are already using these refrigerants in newer cars and portable air conditioners and heat pumps.
R-454B has a lower GWP than previous refrigerants, meaning it has a much lower climate impact. Trane is phasing in the transition to R-454B in 2024, starting with the adoption of R-454B refrigerant in its residential products, beginning with the XR15 SEER2 heat pump.
When Will R-410A Be Phased Out Completely? The complete phase-out of R-410A will likely occur by 2036, when HFC consumption is expected to be reduced by 85%. However, businesses should prepare well in advance, as the restrictions beginning in 2025 will already limit its use significantly.
The new refrigerant changes in 2025 are part of a larger effort to make air conditioning systems more environmentally friendly, while still keeping homes comfortable. These changes are being driven by regulations to phase out older refrigerants like R-410A, which have a high global warming potential (GWP).
In December 2022, the EPA unveiled a refrigerant ban that will go into effect between 2025 and 2026 (depending on the industry). The result? R-410A is out, shaking up the HVACR industry, which relies heavily on this refrigerant.
These refrigerants have a GWP much lower than R-410A, making them more environmentally friendly options for cooling and heating. American Standard/Trane, Carrier, Lennox and other major brands will be using R-454B. Goodman, Amana, Daikin and subsidies will be using R-32.
R32 has the advantage of being a singlecomponent refrigerant with higher energy efficiency and a smaller physical footprint. It's already in use globally, so you can be confident in its reliability. R454B, while newer, has the benefit of an even lower GWP, making it the more environmentally friendly option.
The limited supply and more complex manufacturing process of R454B compared to its predecessor R410A contribute to its higher cost.
The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur.
How much will an R-22 to R-410A conversion cost? The actual cost will depend on many things, including where you live, but most of the time R-22 conversions start at around $2,000 and go up from there. The higher end of that range is somewhere around $4,500 to $4,600.
Ahead of the 2025 regulatory shift, Lennox products, such as the Ultimate Comfort System, will transition to the environmentally responsible refrigerant R-454B.
ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems. At 909, RS-53 has a GWP that is effectively 56% lower than R410a. Additionally, RS-51 (R470B) has a GWP of 717 which is 80% lower than R404a, R507 and half of R448A and R449A.
Changes to the Dangerous Goods Legislation, effective in 2021, has new categories for A2L refrigerants. R32 is a synthetic greenhouse gas. If released to the atmosphere it can contribute to climate change. R32 is a flammable refrigerant.
R-454B. R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in HVAC manufacturing from 2010 until the phase-out is complete in January 2025.
Goodman HVAC systems are produced by Houston-based Daikin Group, the world's largest manufacturer of residential heating, ventilation and air conditioning products and systems.
R-410A is a refrigerant that is classified as a greenhouse gas with a high global warming potential and a negative impact on the climate. It is being phased out for a more environmentally friendly solution for HVAC systems.
Yes, R-410A will still be available for maintenance and repairs for many years. R-410A won't actually be phased out of production until the 2040s. Also, contractors can still reclaim and reuse refrigerant from older systems.
R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
HFC-134a: a Potent Greenhouse Gas
Potent greenhouse gas with a global warming potential that is 1,430 times that of CO2.
If you replace your AC after the phaseout begins in January 2025, your costs could increase by as much as 30%. This is because it's more expensive for manufacturers to produce HVAC systems that use the new refrigerants.
R-454b Will Be the New (New) Refrigerant Starting January 1st, 2023.
R454B: slightly lower capacity than R410A but better efficiency; lower GWP. R32: better efficiency and around 10% more capacity than R410A, depending on the application and system design.
