Starting January 1, 2025, the manufacturing or importing of any product in specified sectors that uses a regulated substance with a global warming potential of 700 or greater is prohibited (40 C.F.R. § 84.54(a)). The specified sectors listed include R-410A, the most common refrigerant used in the HVAC industry.
What refrigerant is being phased out in 2024? The HFCs and HFC-blend refrigerants that are being phased out are: R-410A. R-404A.
Starting in 2023, new HVAC systems will no longer use R-410A. These systems will also be subject to new energy efficiency standards.
Due to the environmental impact of R-410A, the Environmental Protection Agency (EPA) has announced that it will be phased out and replaced by more eco-friendly alternatives. In this article, we will provide a comprehensive guide to the R-410A refrigerant phase out and what it means for homeowners.
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.
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.
The replacements for R-410A are the two A2Ls, Forane® R-32 and R-454B. Forane® R-32 can be used in new equipment designed specifically for mildly flammable refrigerants as a replacement for R-410A equipment. Its low density allows for the use of a smaller refrigerant charge.
Cooling systems shifting from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be implemented in 2025. These new coolants are engineered to be friendlier to the environment and meet updated regulations about global warming.
RS-53 (R470A) is a new non-flammable Drop-in replacement for R410A with a low Global Warming Potential (GWP) less than half that of R410A. RS-53 (R470A) has a similar thermodynamic performance to R410A with matching energy efficiency and cooling capacity.
R-22 (Chlorodifluoromethane), also known as R22 Freon or HCFC-22 Freon, was a common refrigerant for HVAC systems. It is now a banned refrigerant that is illegal to import or manufacture.
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.
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.
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.
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.
A number of common refrigerants, including R134a, R410A and R407C, will be banned from use in new chillers in the USA from January 1, 2024.
It's not flammable and it doesn't create carbon monoxide or other contaminants in the air as it cycles through your air conditioner. However, just because it's inherently safe doesn't mean it can't become dangerous. Any refrigerant, be it R-22 or R-410A, can be dangerous if inhaled or consumed by human beings.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
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.
The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur. Mixing refrigerants is not an option either. This will contaminate the system, and the R22 will not evaporate under the higher suction pressure that R410A requires.
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.
If your system is nearing the end of its life, replacing it before 2025 could be a smart move to avoid higher prices later. Rising Repair Costs: If your system requires frequent repairs or uses R-22 refrigerant, which is already phased out, you might be better off replacing it now.
What are the best alternatives to R410A in air conditioning and commercial heat pumps? R32, R452B, and R454B are all good options for air conditioning systems. However, the best option varies by application. Refrigerants with ultra-low GWP will be important in the longer term.
By phasing out R-410A refrigerant over the next decade, the EPA intends to shift to the use of alternative refrigerants. The new refrigerants, part of the A2L family, must be used in any HVAC system manufactured after January 1, 2025. New equipment will utilize either R-454B or R-32.
A small amount of R 22 left in a 410A system will not sludge the oil. This is because most POE oils are mixable (meaning they mix well) with any refrigerant even R 22.
The Benefit of Waiting
Next-generation refrigerants are more environmentally friendly which appeals to consumers who prefer eco-friendly options. By delaying your purchase, you'll know that your AC system meets future regulations and is more sustainable.
