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.
In compliance with industry regulations, the HVAC industry is shifting from Puron (R410A) refrigerant to Puron Advance (R454B) in Q4 of 2024.
Trane (and much of the residential HVAC industry) has chosen to move forward with R-454B, which has a reduced environmental impact when compared to previous refrigerants. In addition to having a lower GWP, R-454B has no ozone depletion potential (ODP).
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.
R-454b is a drop-in replacement for R-410a, so equipment doesn't have to be redesigned. It's about 60% R32.
The limited supply and more complex manufacturing process of R454B compared to its predecessor R410A contribute to its higher cost. Estimates suggest R454B could be over three times more expensive than R410A (Logan Services Inc.).
Gauge sets used with R-410A should be okay to use with R-454B, although technicians may need to update their digital manifolds to include the newer refrigerants. Standard hand tools like wrenches and tube cutters should be the same.
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.
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.
In fact, R-410A will continue to be produced until 2040. However, as its availability decreases, you can expect the price of R-410A refrigerant to rise by 20-25%. This means you'll be paying more and more for maintenance and repairs of your aging AC unit.
USA: Lennox has become the latest US manufacturer to announce a switch to lower GWP refrigerant R454B across all its residential HVAC products. Last month, Johnson Controls announced the launch of a brand-new suite of residential products optimised for use with the same refrigerant.
R-454B is the new refrigerant in 2024. By 2025, the EPA's required phaseout of R-410A will be in full effect, with production, importation, and distribution no longer allowed. HVACR businesses must be evaluating their current choices in coolant and ready to make the jump.
Like its predecessor R-410A, R-454B poses no danger to the ozone layer. These advantages that led Lennox to adopt R-454B as our primary 2025 Compliant Refrigerant for whole-home systems and R-32 for our ductless mini-split systems.
R-454B, known commercially as Puron Advance™, is Carrier's refrigerant of choice for all ducted and ductless residential and light commercial applications.
R22 (also known as HCFC-22) is a chlorofluorocarbon (CFC) once widely used as a refrigerant. If your home or office AC is over 10 years old, it's probably using R22 freon. However, R22 Freon is banned in the U.S. today.
If you are in the market for a new HVAC system or need to replace the refrigerant in your current system, you may be wondering about the cost of R-454B refrigerant. As of December 2021, the cost of R-454B refrigerant is approximately $8 per pound, according to GitHub.
R454B is THE best-balanced choice to replace R410A for all your building projects where a scroll chiller, heat pump or rooftop unit is needed.
This R454B A2L unit manufactured by Allied Air, uses longer stub outs to allow for brazing with a flow of nitrogen, or you can cut the coupling off and use pressure fittings if that's what you prefer.
R-410A PHASE-DOWN TIMELINE
In 2024, we will jump to a 40% decrease in production. We will reach a 70% decrease by 2029. In 2034, we will see 80% less R-410A being produced than it is today, and the phase-down will end in 2036 with another 5% reduction.
Beginning in late 2024, R454B will replace R410A in all newly manufactured HVAC systems to meet these environmental goals. This change is in line with the EPA's SNAP (Significant New Alternatives Policy) program, which ensures that the alternatives meet both environmental and safety standards.
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.
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.
A: R-454B has properties very similar to R-410A, which is also a blend. Because of R-454B's low temperature glide, leaks can be topped off similar to what was done with R-410A (note that R-410A systems cannot be charged with R-454B; this is strictly prohibited by codes and safety standards).
What refrigerant will replace R-410A in 2025? For whole-home systems, Lennox has chosen 2025 Compliant Refrigerant R-454B due to its excellent performance for ducted systems and zero ozone depletion potential. For mini-splits, we selected R-32, designed to optimize efficiency and reliability in ductless systems.
R-454B/R-32 Implications: because R-454B and R-32 have a mildly flammable characteristic, a non-sparking vacuum pump is required.
