As of December 2021, the cost of R454B refrigerant is approximately $8 per pound (GitHub).
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.
R-410 refrigerant costs $60 per pound on average, but can range from $40 to $75. Keep in mind you cannot purchase R-410A refrigerant without an HVAC pro. R-410A refrigerant prices range from $40 to $75 per pound.
Comprehensive Environmental Impact Metrics
This means systems using R32 typically consume less energy over their lifetime, resulting in fewer indirect emissions. R454B, while also efficient, may require a larger charge size to achieve similar cooling performance, which can increase its overall environmental footprint.
Will R-454B work in existing R-410A systems? 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.
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.
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.
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.
Nothing in it allows for the use of A2L (mildly flammable) refrigerants to be used in residential cooling systems. Mildly flammable refrigerants can't be used in existing R-410a and R-22 systems.
Each make and model of air conditioner needs a slightly different amount of AC refrigerant. According to PG&E, most central air conditioning systems use two to four pounds of refrigerant per ton of cooling capacity. A three-ton air conditioner would typically have six to 12 pounds of refrigerant for a proper charge.
Under EPA regulations, only a certified professional can recharge your home's HVAC system.
R-454B, also known by the trademarked names Opteon XL41, Solstice 454B, and Puron Advance, is a zeotropic blend of 68.9 percent difluoromethane (R-32), a hydrofluorocarbon, and 31.1 percent 2,3,3,3-tetrafluoropropene (R-1234yf), a hydrofluoroolefin.
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.
The same oil that is used for R410A can be used for R454B.
This means that – in most cases – R-454B is not a direct drop-in replacement for R-410A. Only looking at COP may indicate otherwise, but capacity must also be considered. Our test data indicates that R-454B coils will require 10 – 20% additional heat transfer surface to meet the same capacity as and R-410A design.
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.
Exposure hazards: Flammable. In combustion emits toxic fumes. Forms explosive air-vapour mixture. Advice for fire-fighters: Wear self-contained breathing apparatus.
In fact, R-32 is a single component refrigerant, while R-454B is a blend that consists of nearly 70% R-32. R-32 has been safely used in over 160 million units in the US and around the world by more than 40 OEMs.
R-32 is a single component refrigerant, so topping off an R-32 system should not be an issue. R-454B is a refrigerant blend but has a very low fractionation potential and a very low temperature glide, so topping off an R-454B system should not be an issue.
R-454B Refrigerant
Most HVAC manufacturers in the United States (among them Johnson Controls (York), Lennox, Trane, and Carrier) have decided to adopt R-454B (also known as Opteon™ XL41 or Puron Advance™) as the new standard refrigerant to replace R-410A.
With R 454b, the suction pressure will be 113.3 psig . If we have a saturated condensing temperature of 110 degree Fahrenheit, the pressure of R 410a will be 366.4 psig.
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.
R-454B/R-32 Implications: because R-454B and R-32 have a mildly flammable characteristic, a non-sparking vacuum pump is required.
