The R-410A phasedown is on its way, are you ready for it? - December 16, 2020. The HVACR industry is on the cusp of yet another refrigerant phasedown. R-410A is scheduled for elimination from all new systems in 2023. Many HVACR contractors are not prepared for the change, and there are many questions. Here are some answers.
Why is refrigerant transition so complicated?
The refrigerant transition is complicated by the fact that it is occurring on a state-by-state basis. The timing and requirements may not be consistent depending on the contractor’s location which leads to more complexity and therefore, confusion.
What amendment is used to lower the use of HFCs?
The effort to lower the use of HFCs on a global level is being driven by the Kigali amendment , which calls for a phase down in prescriptive steps. The U.S. has efforts underway at the federal level to pass legislation to phase down the use of HFC’s through the AIM Act.
Is flammable refrigerant a model code?
As a result, the proposal to add mildly flammable refrigerants into the model codes was voted down and is now being considered for the 2024 code cycle. At the state level, Washington has adopted UL 60335-2-40 3 rd edition and ASHRAE 15 2019 edition into their state building codes.
When will the phase out of XYZ refrigerant begin?
So, if a phase out was announced today on XYZ refrigerant the actual phase out most likely wouldn’t begin until 2020, at the earliest. This was the case for the HCFC refrigerant R-22 and it is the same case for HFC refrigerants under the SNAP Rule 20.
What happened to the EPA's snap rule 20?
Remember at the beginning of this article that I said that all of this could change? Well, there was some drama over the summer of 2017. In August a federal court ruled that the EPA’s SNAP Rule 20 overstepped the EPA’s authority. The ruling in essence overturned the EPA’s Rule 20 and removed the planned phase outs of HFC refrigerants. In the SNAP Rule 20 the EPA used Section 612 of the Clean Air Act for their justification. This section of the Clean Air Act strictly specifics on products that contain Chlorine or that cause damage to the Ozone layer. HFC refrigerants do not contain Chlorine nor do they cause ANY damaged to the Ozone. The courts looked at this and ruled in favor of the filing companies, Mexichem and Arkema, and against the EPA. I wrote more in-depth on this ruling in a previous article that can be found by clicking here.
What is the EPA's rule for SNAP 20?
This section of the Clean Air Act strictly specifics on products that contain Chlorine or that cause damage to the Ozone layer. HFC refrigerants do not contain Chlorine nor do they cause ANY damaged to the Ozone.
What is the new rule for HFC refrigerants?
In the summer of 2015 the Environmental Protection Agency added a new rule to their Significant New Alternatives Policy. (SNAP) This new rule, labeled Rule 20 , was designed and targeted towards phasing out Hydroflurocarbon refrigerants. HFC refrigerants include some of the most popular refrigerants used today such as R-404A, R-410A, and R-134a.
When will refrigeration units be unacceptable?

Is R-410A phased out?
Well folks, as I explained above there is no cut and dry date when it comes to R-410A being phased out. Each type of application has a different set of rules and years that are associated to it. The EPA has provided an official fact sheet on their Rule 20 and the phase outs associated to it. This is a large document consisting over six pages with a lot of text, so to make things a little easier I’m going to break it down for you below in the next section. If you prefer to read through the document though by all means go for it!
Is 410A a SNAP rule?
It’s a big one and it wasn’t included in the SNAP Rule 20. Yes, that’s right residential air conditioners are not included in this phase out of R-410A. What that means is that we are good to go to keep using 410A for your home or office air conditioner, at least for a while.
When will R-410A be replaced?
August 2, 2020. The big debate in the HVACR industry right now is which refrigerant (s) will be chosen to replace R-410A in many types of comfort cooling equipment. Countries around the globe are already phasing down HFCs, and various states in the U.S. are passing legislation that would also minimize the use of these high-GWP refrigerants.
Why is R-454B chosen?
Our solution, R-454B, has been chosen because it provides a solid foundation, both financially and environmentally, making it the optimal choice .”. Swilik agrees, noting that R-32 has a significantly higher GWP and would most likely need to be phased out itself as GWP levels are lowered over time.
What is carrier R-454B?
PRIMARY SOLUTION: Carrier recently announced that it had chosen R-454B as its primary lower-GWP solution to replace R-410A — such as the unit shown here — in all of its ducted residential and light commercial packaged solutions sold in North America.
Do A2L refrigerants need to be trained?
Before working with A2L refrigerants, technicians will be required to attend industry-sanctioned training sessions, and Carrier is also creating a curriculum for its own technicians, said Swilik.
Can you use R-454B with standard equipment?
For service, standard equipment will still be used, noted Swilik, but tools will have to be certified for use with A2 L refrigerants, such as recovery machines.
Who makes the R-454B?
The main reasons why R-454B, which is manufactured by Chemours under the trade name Opteon™ XL41, has become one of the leading contenders to replace R-410A is that it closely matches the properties and performance of R-410A while having a GWP under 500.
When will carrier A2Ls be available in California?
Manufacturers such as Carrier are not waiting, and they are in the process of developing, qualifying, and certifying their new products to meet the new standards going into effect in California on Jan. 1, 2023.

When did the R-12 replace the R-22?
In 1994 R-12 Refrigerant was discontinued and replaced with the HFC R-134A. The same thing happened with R-22 in 2010. In 2010 it was mandated by federal law that all new air conditioning machines would take R-410A Refrigerant instead of R-22.
What is the R-22 refrigerant?
Why is that? Well, R-410A is the go to replacement product for R-22 Refrigerant. R-22 was the standard refrigerant that was found in all home air conditioning units. If you had an AC unit it took R-22 that was all there was to it. The problem with R-22 is that it fell into the class of refrigerants known as CFCs.
Is R-134A an HFC?
The government is pushing this not because of O-Zone depletion, which R-134A does not contribute, but because HFCs contribute to Global Warming. The measures are voluntarily at this stage, but they have set their sights on R-134A. I bring this up because R-134A is an HFC refrigerant. R-410A is also an HFC refrigerant.
When will R410A be phased out?
Hello - R410A is THE refrigerant everyone is using these days (new units) and EPA already announced its mapping to phase it out starting 2024. Due to the professional work I do this week came to understand under the new revised executive directive towards green-house gas reduction this notification will be revised by Q3 2021 to a much aggressive timeline and date inclusive of both residential and commercial establishment. I can NOT validate this but what I got is revision to 2022 Quarter-4 and timeline will be published, which is 4 to 6 years from 2022 -> complete manufacture stop including imports.
What refrigerant is used in a Diakin 410A?
Diakin’s future refrigerant to replace 410A is going to be R32, Carrier say’s they will be using the R454B they call it Puron Advanced. So, what happens now, if we use R454B in a Diakin and the compressor kicks the bucket, will they send it to the lab to try and deny our warranty? And vise versa, will Carrier do the same? So, it looks like we all get to carry both refrigerants on our trucks now, for your common residential a/c systems, not to mention the 2 to 3 jugs of the different alternatives for the old R22 systems. Yep! The future looks really bright for our trade.

The refrigeration and air conditioning (RAC) industry has moved through significant refrigerant changes since the early 1990s because of environmental concerns over ozone depletion and global warming. To date, CFC refrigerants have been phased out, virgin HCFCs are no longer available in Canada, and certain HFCs are being phased down because ...
What is the regulatory issue affecting the new low GWP refrigerants?
In Canada, a regulatory issue affecting the new low GWP refrigerants is the requirement to have them listed in the building code of each province where they are proposed for use. The code committees and authorities will have to consider issues such as the mildly flammable rating of A2L refrigerants, and whether the alternatives can be used for retrofit applications as part of the approval process. The time needed to have these refrigerants approved and listed in the building codes is a key factor in determining when these alternatives will be introduced to the Canadian market.
What equipment was left off the list of equipment under the new regulations?
Specifically left off the list of equipment under the new regulations was light commercial and residential air conditioning equipment (LCRAC). Both the Canadian and U.S. governments agreed to delay specific regulations concerning the LCRAC sector to allow refrigerant and equipment manufacturers more time to develop alternatives for R-410A, which is the predominant refrigerant used in this sector.
Why is it important to tap into reliable resources that provide information on the new generation of refrigerants?
