The 2023 refrigerant transition has many HVAC contractors asking questions. The ACHR NEWS connected with four industry leaders to walk us through what this means for the contractor. Read more about refrigerants. bit.ly/3WOw2Ai
I work in HVAC and was told the R-454B leaks into your house when there is a leak. I'm not sure what that means, but I know it's not good. From researching myself it seems like R-32 is better because it has been well tested.
Full of bs. Any freon higher pressure of 300 and micro channel leak cannot be repaired every them would coming whit new freon and more law for the epa am technician a see the only. Make. New staff to make money for the consumer bid company and law makers make deal behinds doors to get rich
If that's the case, how have cars successfully used microchannel condensers for the last 3 decades? Cars see head pressures of over 300 PSI all the time by design and their condensers rarely leak unless hit by debris. Seems to me like the issue has more to do with poor quality coils than the microchannel technology itself.
ok my question is from a homeowner or rental property owners perspective... should I wait until new systems come out to replace dying units (I still have a few R22 systems)? How likely is it new systems with new refrigerants have serious problems to work out?
a r410a unit will work just fine and i dont think you need to wait for a new unit. You should just wait till it goes out and have money saved for a new unit
@@luismigueldelatorregalvez9448 I'm talking about units that have already gone out. The question is to replace the unit now or suffer through and wait for the new refrigerant systems. It's got nothing to do with saving up money. The dilemma is... the same as for an R22 system currently. It costs $1000 to fill a leaking R22 system because R22 is no longer produced and is difficult to find. Generally you can only find it in reclaimed/used canisters. Sometimes the sellers are lying and selling you something else labeled as R22. The same thing will happen to R410a sysetems in 10 years when they start having problems.
Yes wait, if you replace with 410 system and it goes out in 5 yrs you’ll have to replace whole system again as the 410 equipment is being stopped production
@averyalexander2303 No building codes outside of most incorporated areas. Ammonia is toxic and dangerous but the anhydrous form sure makes the corn grow!
@@darinmeritt3790 Yeah, it's definitely a great refrigerant, just totally unsuitable for use in any equipment untrained people may be around or messing with. One possible solution may be for the refrigerant system to be self contained and completely outside and chill water instead of the air directly, but the efficiency loss from chilling water to chill air would probably more than offset the gains from using ammonia in the first place. Still not a good idea for many reasons IMO, but it's at least much less of a terrible idea than running the ammonia through the house.
Always been a scam from the Montreal protocol to pure politics. This is a flammable liquid. Reminds me of exploding lithium batteries no media is covering . sick evil politics.🎉🎉
You look at the operating pressures you'll see that they're so close you'll be able to dump whatever in whatever.. This will cause a refrigerant contamination nightmare ..
@@shanebrooks2013 I mean me personally they can do whatever I pretty much got enough refrigerant for myself they're basically giving away old r 22 systems now I'll slap a 410A condensing and evaporator coil change my metering device and has some cold AC rockimg God old r12 before I pay for all that new stuff personally I understand not everybody can do that But that's why I live in the country I didn't need a permit when I built my full length enclosed front porch either. Noone cared .
@@shanebrooks2013 is it the EPA's fault if someone is mixing and matching. that is like me blaming the government for me mixing kerosene in my diesel truck.
Daiken had first 3 guys on here who basic said nothing but that it is announced. lol so, stop being in love with your voices and say what is happening. that's all.
r152a is a drop in replacement for r134a. Fill to 12% lower pressures. Can be mixed in any ratio. Very cheap. I source from certain "air duster" cans & use a side tap valve.
Contractors don't have a lot of choice, since there is little if any A2L refrigerant equipment currently available. As new A2L equipment becomes available, it will likely be more expensive than new equipment with high GWP refrigerants, at least until the old inventory is sold and new inventory takes it's place. I'm basing my answer on experience from the last 2 painful transitions.
Because the change in climate does not always result in warming; it can also result in increased trends in storm activity, cooling, shifting in glacial patterns, etc. The scientific understanding of climate change has advanced beyond just the "hole in the Ozone layer" making it hotter.
Leftists couldn’t make up their minds if the earth is cooling or warming. They just want an excuse to tax the heck out of you and stop all consumption of fossil fuels. The truth is that Earth’s climate has been constantly changing long before the first man appeared.
Because a lot of places are having record cold and they don't want to be embarrassed. Similar to the way they changed the definition of "vagzine" after people who had 3 or 4 doses still got the c19.
@@realSamAndrew I haven't been able to find it. Are you saying you can't either? If it had come up for me I wouldn't be asking. I wouldn't consider it rude if you had a source accompanied with your criticism of my search efforts but since you purport to know yet have no source, well, I needn't spell out what that looks like.
@@elgringoec you came here to ask. I answered you, and you asked me for proof? If you were going to question the answer, why even bother to ask? I was the only one so far to do you the courtesy of even attempting to answer you, so yes, I am insulted. And I also now believe you are either lying or deliberately trying to agitate. Why do I say that? Because if you take your exact question above and type it in verbatim to Google, you will have about 12 answers on the first page. If you tried already, you didn't try very hard.
Im watching your webinar on a2l now. You guys are getting rich on a bunch of contradiction lies. First of all i call BS on the mildly flammability . Its either flammable or non flammable period. Second of all its not the same as the 2010 change to R410a .. because the industry wasnt robbed by an overpriced replacement refrigerant. Also whos gonna pay for all these special tools?? I work for a not for profit college. There certainly not gonna pay. Always the little guy who gets screwed.
In the commercial field we have to crawl climb into all types of confined areas..last thing i want in there is a flammable product. If its so harmless why do we need spark free tools?? Again BS!
Well, don't know which government he represents? nor which consumers he is advising? a) R32 or R454B are A2L class flammable, (can be explosive), more toxic than A1 class, refrigerants while all existing refrigerants CFC, HCFC, HFC are A1 class NON-FLAMMABLE non-toxic, non-explosive, odourless b) There is no phase-out of HFC (ps R32 is an HFC!!!), but there is a phase-out (not ban of stop supply) of Hi GWP (any refrigerant) ABOVE 750 and not until 2027 and in some countries 2045 AND there are already low GWP A1 class, c) The gentleman ignores that fact that A2L is flammable and can be explosive (diesel effect) and the 1st in domestic and commercial application since 1928!, d) He is ignoring Health & Safety regulations and MUST requirements & limitation of USE of A2L class refrigerants1!! Surely the press should check credentials? or is it journalism that should not be used as this subject can lead to life loss and consumers must not be confused by the ignorance of some dishonest manufacturers like Dikin!!
