New refrigerants are coming and in today's video? I Want to talk about five things that we're going to see that are different about the application, the designation, and all of that with these new A2l refrigerants. During the recording of this video, we're beginning the phase down of 14a refrigerant. We're in year three: I Think of the AA the beginning of the phase down to 410A and over the next 24 months 12 months probably we're going to see these A2l refrigerants be introduced. We've already seen a couple products hit the market.

We're still waiting for some states to approve the refrigerants, and I Thought it would be great to do this video so you can see five things that are going to be different. First of all, what are A2l refrigerants just? In summary, we could probably do a three-hour video, all the ins and outs and why companies are doing this and versus that and all these different things. But ultimately, they are mildly flammable refrigerants. And when I say mildly I mean very mild.

But because they're mildly flammable, a lot of changes are being made in the industry. An endless amount of changes it seems like. But I Thought there would be five things that we should probably cover that Pros and homeowners alike would be able to decipher, tell the difference, and so on. So let's dive into it.

Number one: The first thing is, you're going to see red bands or red stickers, red designations on the refrigerant cylinders, among other things. When dealing with these new refrigerants, they're basically meant to stick out. They want folks that if they're holding that refrigerant tank or if they find it to know immediately, this is an H 2 refrigerant. It's different.

It's unlike 410A or R22 or any of the other refrigerants that we deal with. This red band is telling us hey, this is an A2l refrigerant now I will warn you I Think it's possible that you might lay hands on a jug of R32 or R454b because I have seen them that came out before this whole red band thing. So just realize just because it doesn't have a red band doesn't necessarily mean it's different. It doesn't mean that it's not an A2l refrigerant.

It doesn't mean that it's not mildly flammable. I Think we're going to see that a lot. We're going to see things being done a certain way. and then all of a sudden you know some sort of change or regulation is going to kick in in our industry and we're going to see a difference, right? So just realize just because it's a jug of R32 but it doesn't have the Red Band doesn't necessarily mean that it's any different.

I Wanted to take a quick break from the video and thank the sponsor of this video. Aeros Seal Leaky Duck Workor is one of the biggest, if not the biggest energy wasters in most homes in the United States and my favorite way of fixing that problem is Aeros Seal They'll come into your home, they'll test your duct work and how leaky it is. They'll seal all the duct work with a machine and then they'll test it again and make sure that you got what you paid for. Customers have reported a significant savings on their energy bills after using Aeros seal.

I'll put a link down in the description of this video. Thanks again the AOS seal And now let's get back to the video. Number two: A lot of these products are going to have left-hand threads. So When you buy a jug of refrigerant and you're trying to connect your gauges to it, you're going to need some sort of adapter and this is not uncommon.

We've seen other products on the market that are different than the norm. I Remember years ago, they had a specific thermocoupler that came out for certain water heaters and it had left-hand threads. But just realize that your normal right-and threaded gauges a pro might normally carry on their truck may not connect to these new cylinders simply because they have left-hand threads. Number three: A lot of refrigerant containers or jugs used to have this cap, right.

so if you got to dispose of the refrigerant tank, it's got this little tab there that you're supposed to remove. It's not a big deal, normally just a the back end of a claw hammer or something like that and you just break that tab open and and then the container ER is completely. you know, empty and you can dispose of it properly or recycle it or whatever the difference is with these newer refrigerants, they're going to have a springloaded type cap. The reason this is important is because when you are transporting, so if you're a pro and you put this jug of refrigerant on your van, you want that tank to be in the upright position.

They're saying that if it's laid horizontally, that spring could allow some refrigerant to leak out I Don't know if that's true I haven't laid hands on it, but ultimately just realized instead of having that tab there, you're going to now have this springloaded looking type cap over that same hole. They're saying that this springloaded cap is going to be like a relief valve, that it's meant to release extra pressure, higher pressures to bring it below the cylinder's max pressure. I Have not laid my hands on a tank of it yet, but I would guess that this has to do with temperatures as well. So a lot of us know that if you have higher temperatures, that it means higher pressures in the heating and air industry when it comes to refrigerants.

And so if you've got got this tank of mildly flammable refrigerant that gets really hot I'm guessing that spring-loaded relief is meant to avoid, you know, a problem, An explosion if you will. Number four: I Think you're going to see lots of scary stickers and lots of different labels. You're going to see flammable and these triangle looking scary looking caution stickers that you've never seen before. They're going to be on equipment.

They're going to be on the refrigerant tanks. probably. They're probably going to be on certain tools anywhere that has anything to do with these types of refrigerants. I'm guessing you're going to see big scary languages and big scary stickers and so on.

Just to warn folks. hey, you're laying hands on something here that is mildly flammable or just flammable in some degree, right? And then finally, you're going to see some changes to the equipment itself. You're going to see sensors that sense the refrigerant leaks. You're going to see components that avoid ignition.

So when you saw contactors that were open before, we're going to see those closed. And that's not uncommon. We've seen those before, but we're just going to see all the devices intentionally definitively meant to avoid ignitions of some type. You're also going to see equipment that is designed to continue to run the fan if there's some sort of problem.

And that's also not uncommon, especially with gas furnaces. When it goes into a specific type of error code, it's going to shut certain things down. go into an error mode, a lockout mode if you will, but continue to run the fan through that system and so on. I Think a lot of these things are going to be code I've already heard that they're going to the manufacturers and pushing some of these things, and in some cases it's going to mean that the equipment itself.

if it's a communicating system, it's going to be all in the programming. But if it's a non-communicating system, you're going to probably see extra components. You're going to see some sort of board added to that system that's designed to run that fan if there's an issue. So ultimately, I think we're going to see even more changes.

These are the ones that are definitively coming. They're the ones that we're already being warned about as Pros In this industry, the top five things, Let me know what you think comment down below: Are you concerned about these mildly flammable refrigerants coming to? North America They've been used for years, overseas, and I think that's great. but I Do think that you know there's a lot of guys out there that have never touched these types of refrigerants and now they will. So I think there are some challenges? Let me know your thoughts.
