R22 HCFC, the hydrogen atom would break off and it was far less likely that the gas would carry to the ozone layer. The EPA kept moving the goalpost, they went from the ozone layer to this global warming potential. I got my EPA certification back in 1994. I once believed that we were going to take out the ozone. Solar activities and thunderstorms regenerate ozone. One vocanic eruption will carry more clorine to the upper atmosphere than most of our now banned cfcs combined.

Good question!

If the systems are going to have safety measures that detect leaks, they might as well just go for R290 propane. It has a GWP of 3 and is more efficient in a system. And best of all , it is cheap.

The drama over flammability is hilarious considering that I have a couple of camp stove propane bottles in my garage and a mapp gas bottle. Leaks are normally miniscule and the chance of a dangerous accumulation of gas is next to nothing. Just rip the band-aid off and switch to straight up hydrocarbon refrigerants like propane and butane. For small systems and self-contained roof-top units.

Thanks for the heads up on these new refrigerants. Since R410a will increase in price because of being phased out, it may be wise to buy a new HVAC system with R32 in it if one is replacing their current system.

[@threeftr3349]

Yes, R410A refrigerant eventually it will increase, a lot is due to inflation, the metal containers it comes in, due to metals going up, and the fact that most of it comes from China. That container ship carrying all those jugs of R410A has seen costs quadruple in recent history R410A refrigerant will most likely be around a good 15 years, because they are still selling them. Why replace an expensive working unit, until it's absolutely necessary to replace?

[@dre8310]

Just went to a A2L Training and they informed that R-32 will only be around for about 5 - 6 years due to GWP not meeting the required standards in the future. Not sure how true this is. R-32 GWP:675 R-454B GWP:466

[@my-yt-inputs2580]

This is time important for me. My son was checking out my 2 systems just yesterday. A little too cool however for accurate refrigerant levels. But I have a package unit from 2008 that may be due for replacement which of course uses R-22. That one was installed new in Nov of 2008 followed shortly by the switchover to 410A in 2010. So if I am going to replace the unit soon I want to ensure I get one with the newer refrigerant vs R-410A. Looks like I'll need to look for a system using R-32 vs 454B.

[@jasoncook6121]

york picked 454b because its lower GWP and hoping to get past next round which is looking like propane with water chiller

[@per995]

You made excellent information about the refrigerants and what to expect in the future. In my place the air conditioning and heat pump units solely use R 32 and done for several Years My son has a 18kW pool heat pump and two smaller for the house on R-32, running 5years now Seems to be the best product out there right now even in very cold outdoor temperatures. R410A is not a good choice in Europe due to the phasing out and the rising prices. They reduce the production too so we know what that will happen with the price and how accessible it will turn out soon. I have struggled a lot with high GWP refrigerant, mostly in cascade systems over 35 years. It was easy to buy back when you had R-13 and later R-23. It changed to an azeotrop mix of R-13 + R-23 to the mix R-503. The R-23 period made a lot of high discharge temperature failures/damages. The 503 ,good working, was the hard beginning of accessibility and wild prices. The latest now is the 508B/Suva 95. The GWP is horrible and the price and tax is out of this world. You cannot get 508B now so it is so many expensive units running like ULT freezers, climate chambers,, ULT chillers cold traps and on that has to be thrown at the junk yard. The last time we bought 508B the price was $ 700 by 1 Lb and the tax running at $ 700 on top. We sold a freeze drier lately with 508B charge at $ 120.000 and the manufacturer know that to recharge the low stage on it is not possible due to the lack of 508B What a scary situation on systems that are going dead if a leak occurs. The smaller ULT systems here are solely using hydrocarbons like R-170 Ethan R-1150 Ethen, but the all system often with R-290 propane in the high stage can totally be 8,8 oz or 250 gram. It has ended up as a horrible situation due to the charge is not sufficient to run like an ULT freezer. Almost all units compressors run a full time and the compressors never receive a proper suction gas cooling. We have never seen so many fatal failures on the units now that is charged with hydrocarbons. It is a huge nightmare to handle the problem that is bigger than most people know of. It is not a solution to find and it destroys the whole ULT business now.

[@tonyking8864]

Good video, very informative. However there are only 2 to 3 manufacturers that will be using R-32 in American split system and rooftop products (non VRF). It should be noted that the MAJORITY of US manufacturers have chosen R-454b. One big reason is because any manufacturer using R-32 will have to re-tool their whole product line AGAIN after the next Global Warming Potential (GWP) phase down in just five years from now. R-454b has ten years.

R454B will be eventually banned due to the last part of your video. PFAs are a real concern. These companies pushing for 454B should be a concern. The obviously only care for profit margins, and not the environment. This is all about money, They are using 454b due to it being a single brand under a patent. It will cost way more than a refrigerant not under a single brand patent like R32. Once the patent runs out on R454B, they will try to make up some other environmental concern to make companies switch once again. This will never stop till we get some laws changed.

[@TenTwennyDollaBills]

This hoopla really won't do a thing for the environment. Feel good nonsense. You maybe lose an ounce of refrigerant a year in a tight system. Compare that to a diesel truck.

I think this is an excellent video, and I basically agree with your 'favorite' new refrigerant and your reasons why. But that next reduction in GWP is real. And R32 won't be able to meet that, resulting in yet another refrigerant (and system) changeout in another decade or so. And all new cars in this country are already loaded with a full charge of 1234YF, so its not like its not already out there. The one thing that scares me is what you already stated: "one refrigerant that a lot of these brands seem to be going with" ...which is R454B. That's at least 4 out of the 6 of the main parent companies of all brands of all AC systems. And probably will end up being all of them. But this same topic has been actively talked about or the last 3-4 years. We are now in the second half of 2024, with federal legislation stopping 410A going into any newly manufactured AC systems starting in Jan 2025. And we're STILL talking about which refrigerant to choose?? Kind of reminds me of the Democratic party (to which I belong) and its current mini crisis on who it thinks should be the party's nominee just 5 months before the election? Hint: it also will be the one everyone has already chosen.

IMO buy a propress now and a high silver percentage solder, to attach stubs if needed for propress fittings, to avoid brazing and possible fires now and in the future.

Daikin your sponsor is going with R32 because they already produce R32 systems. Daikin is investing in hopefully long term being able to develop a refrigerant with a GWP of 10 with "AI Technologies". But either way being able to avoid further GWP phase downs (Along with owning the patent potentially to a new ultra low GWP refrigerant) is financially best for Daikin. Rheem on the other hand has produced mainly F410A of late. And switching to R454B means they won't have any another potential cycle of phase downs in 2029.

Hi thanks for the video. But you hinted that a lot of this could be political and agree just to mention that. But I found this worth reading, but I did not research it's facts. It's an interesting read. The Relationship Between R1234yf and PFAS Although R1234yf itself is not persistent or toxic, its structure classifies it as a PFAS. However, when R1234yf decomposes in the atmosphere, it transforms into Trifluoroacetic acid (TFA). TFA is considered a PFAS compound and exhibits persistence. When TFA comes into contact with soil or surface water, it forms salts with minerals like Sodium and Calcium, behaving similarly to other mineral salts. While TFA is soluble in water and can accumulate in salt lakes, beaches, and oceans, it is not highly toxic and poses minimal risk to human health, as stated by UNEP.[1] It is worth noting that TFA is naturally produced by undersea volcanic activities, and a significant amount of it found in the ocean can be attributed to this natural source. In a bi-partisan effort, the US Senate is currently drafting a bill to provide a consistent and practical definition of PFAS compounds, specifically excluding refrigerants and their decomposition product TFA and only focusing on the proven toxic and problematic substances, that can easily migrate into the environment

[@NewHVACGuide]

Good information. I've read several articles that seem to be pointing out information on both sides of the argument. The concern here is not just whether or not PFAs are a good thing or if this refrigerant poses risk. Part of the conversation if certain refrigerants could be banned in the future.

[@TheGgin]

@@NewHVACGuide Yea, I totally agree. There are some things out there is not making sense, but that is how it has been for a while. Right now future bans are pretty much based on GWP, but maybe PFAs will come in. Been taking the R454B training with Carrier and if the base on GWP only, R32 will be up first...but we will see.

R-22

@@mmr0221 Lol, my 24 year old unit is still running!! And I have a R22- 3 ton all in one 16 yrs old, it will freeze and heat you out of our room addition

[@zurikin]

when they release "new refrigerants" how do you update your existing digital gauges to be applicable.. do you need to or are they already pre-loaded in your gauges

[@NewHVACGuide]

Digital ones will probably just need a firmware update. Analogues won’t have the saturation temperatures on the dial unless you buy new A2L compatible gauges.

[@JosephWett-vw7zp]

Daiken owns R-32 I believe.

[@NewHVACGuide]

They released the patent years ago 🙂

[@dillonbray]

Which brands are going with R32?

[@NewHVACGuide]

I don’t know all of them but 3 are Daikin, Amana, and Goodman. Several minisplits too

[@InsidiousDr9]

"Asian safety standards"

[@jakeholcombe4002]

These are not even new R32 is in 410a and funny thing is 454 and 32 are still HFCs

[@boanerges5723]

But I'm sure they used the words "greener", "sustainable", and "synergy" in the presentation so it's clearly better

[@dgapp76]

It's all about GWP

Well, there is always transcritical CO2 technology

Can you replace R22 with R23?

No sorry

R-32

[@bigdaddy5948]

R 22 is the best they ever made

[@NewHVACGuide]

Would be nice to get back to lower pressures

[@Bakin]

Do you have any information on which manufacturers will be using R32 refrigerant?

[@maxd4968]

All brands do outside of the US and have been for a decade

[@Deaftractor]

r-32 has high pressure on compressor cause blower hot air outside make the earth hot. R-22 has low pressure has less hot blower

[@wilymcgee]

i hope they discover CO2 soon :P

[@boby115]

Use it in commercial refrigeration already (pressures are extremely high & the equipment is extremely heavy duty and expensive $$$). I would like to see R290 used ; It would need to be in a chiller application (this would keep the R290 / propane outside of the home).

[@wilymcgee]

@@boby115 I totally agree with that. I know two pipe is a no-no commercially but hydronic cooling could be pretty cool (pun always intended) residentially since loop sizes would be low volume. Then it could be a heat pump chiller using 290. I’m still rooting for CO2 (744 or whatever it is) as the ultimate clean refrigerant. I think it’s a bottom line type thing…. Who’s gonna make $ off co2 as a refrigerant…

[@Jon-hx7pe]

@@boby115 it's better to have refrigerant that can't go boom especially when compressors can blow terminals and arc causing a major fire if refrigerant is flammable.when leaks go un-noticed. being non-flammable used to be considered necessary to be used as a refrigerant in appliances and most hvac equipment.

You said you weren't going to get into politics. But just mentioning, in a way that implies it is real, carbon footprint nonsense and anything that references carbon dioxide (proven to be not a greenhouse gas), or anything to do with the political fiction of GWP, you have jumped right into politics, and away from the science. The video is therefore downvoted.
