When Will R-410A Be Phased Out Completely? The complete phase-out of R-410A will likely occur by 2036, when
Yes, 410a is being phased out but manufacturers will continue to offer parts support for their 410a equipment past the 2025 cut off date.
R-410A won't actually be phased out of production until the 2040s. Also, contractors can still reclaim and reuse refrigerant from older systems. This means R-410A will be available, and we'll be able to service these units easily for the next 20 years.
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.
The replacements for R-410A are the two A2Ls, Forane® R-32 and R-454B.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
Basically, federal standards will require a new type of refrigerant to be used in brand-new home HVAC systems. Right now, cooling systems are required to use HFC and HCFC refrigerants, like R410a. The new guidelines will require A2L refrigerant to be used instead for all systems manufactured after a certain time.
Regulatory Changes: As the phase-out continues to restrict production levels and importation, the R-410A price will likely increase. Manufacturing Costs: Fluctuations in the cost of raw materials and manufacturing can also influence the price of refrigerants.
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 Lennox choices for 2025 Compliant Refrigerant R-454B for whole-home systems and R-32 for mini-splits, both have a lower GWP than the previous refrigerant and are formulated to provide excellent, reliable performance of your system for years to come.
R32 has a GWP of 675, roughly 30% lower than that of R410A. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate. Ozone Depletion Potential of 0. Easier to recycle than R410A, as R32 is a single-component refrigerant.
Beginning January 1, 2025, the EPA will no longer allow manufactures to build residential ducted and ductless HVAC equipment using the current R-410A (Puron) refrigerant.
If you're planning to replace your AC in the near future…
At the time of writing (summer 2024), it's still possible to purchase systems that use R-410A refrigerant. The systems available today are less expensive than the systems that will be available to homeowners in 2025 and beyond.
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.
In fact, one kilogram of refrigerant R410a has the same greenhouse impact as 2 tonnes of carbon dioxide, which is the equivalent of running your car for 6 months.
R410 Refrigerant Phase-Out Timeline
This decision stems from the fact that R410A is a hydrofluorocarbon (HFC) with a relatively high GWP compared to other options. Starting January 1, 2025, newly manufactured HVAC equipment may no longer use R410 refrigerant. The new industry standard refrigerant will be R454B.
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.
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.
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.
A three-ton air conditioner would typically have six to 12 pounds of refrigerant for a proper charge.
R-22 was a commonly used refrigerant that is being phased out because of its harmful impact on the ozone layer.
R410A has a high VCP, which requires larger pipes. Thus, it's not as efficient as R32, whose VCP is significantly lower. Moreover, R32 has a higher pressure ratio than R410A. Overall, R32 is much more efficient than R410A.
Yes – universally, new air conditioners and installation will be noticeably more expensive in 2025. You will save significant dollars by buying and installing now.
