It's time to chill out and get ready for a mediocre. Qa live stream if you're old enough grab yourself your favorite adult beverage and if you're not stick with apple juice, put your feet up and relax. If you have any questions, feel free to ask them in the chat and now, let's queue up the intro music yo, hello, everybody. How are you guys doing this evening? Hopefully you guys can all hear me well um.

Hopefully you guys had a Happy New Year. We had a great one over here, just nice and relaxed nothing too crazy. So that's always good right, but I don't know about you guys, I'm like super stoked that everything's over, like you know, I I totally appreciate and love being around family and having time off, but it just makes everything so chaotic for me. Maybe it's different for me because I'm a business owner so it just screws up.

You know the last three weeks of December are just a nightmare just trying to organize and orchestrate everything. So it's definitely definitely a challenge. But again I really appreciated being able to see all the family and everything that you usually do around the holidays. So I do like that part, but I'm just I was ready to start today because today was the first day back to like normal work week.

You know as a business owner too, it's kind of stressful for me, because I'm taking some vacation time here for the HR conference at the end of this month, and so that, like builds up anxiety like a knot in my chest, just thinking, okay, I'm gon na - Be taking off, you know, I'm gon na be gone for a week like uh, but you know it's just the little things I obsess about stuff and I know I have mental problems but yeah. It is what it is, but for those of you that are new in here, you know my name is Chris a little bit about myself, I'm an HVAC hour service, technician, business owner and I make these videos to help out the next guy. Okay, I do want to make something clear, though, because I know that I've been getting YouTube's been recommending my videos to a lot of people that are not in the industry, and I think that's great, because I want to share a little bit of knowledge that I Have with everybody, but I also want to share with with the general public. You know the kind of stuff that we see and do so that way they can be a little bit more aware.

So I think it's a good idea that you know people outside of the industry is watching these videos, but I do want to make one thing clear in no way - and I don't mean offense to anybody, but in no way are my video is meant to encourage You to try to fix your own equipment. Okay, you can do whatever you want to do with your own equipment. That's your prerogative, but my videos are men for service technicians. Okay and again, I still think they have value to people that aren't technicians, but I the the comments that I get.

I've been getting an influx of them alike. How come you don't show me how to wire this entire walk in from start to finish? How come you don't show me all the details like show me how to set up your torches and all that okay see that's not what my videos are for. Okay - and I don't mean a fence - and I don't you know, I know, there's other channels that do that and that's just not my style. Okay.

In no way do I want my videos to to replace or to take a service technicians job all right. I just want to be able to share the little bit of knowledge that I have with other texts, and you know so. I think it's great that other people are watching these, but I also just want to make it clear. You know, and I don't mean to be rude or anything: okay, I'm just not a DIY Channel.

That's just not what it is. So I'm not gon na tell you and I can usually tell from the questions you know I can tell if it's a technician or not and I'll answer them and I try to be polite as possible, but I'm not going to tell you how to fix your Equipment: okay, because there's a lot of texts out there and I want to keep them working, and you know we have a very interesting skillset in the HVAC trade, and you know I know you guys that are texts that are watching this understand. What I'm talking about. Okay, so - and I just want to reassure this - I do get comments to from HVAC our business owners and service techs, saying you shouldn't be showing that stuff people are gon na try to fix their own thing.

I leave out so much in my videos. Okay, if someone can figure out how to fix a walk-in cooler from what I show in my videos, they're pretty smart person and they were gon na. Do it anyways, so you know alright. Another thing that I do want to make clear: it really really helps us if you guys put your questions in caps, lock.

Okay, we're really really trying to get to these questions, so please just hit caps lock or hold the shift button down while you're typing okay. So that way we can try to get to these questions as much as possible. Alright, another little thing I swear. I have to mention this.

Every single stream, but I do okay - is that you know I try to protect my customers. Okay, if you guys think that I work in nasty restaurants, then you guys don't know what nasty restaurants are, because I really don't and the stuff that you see in my restaurants, you sometimes it might be a little bit gross, but it's actually pretty common amongst all Restaurants out there, but for that reason I'm protecting my customers and I don't reveal the locations that I work at okay. So if you guys are trying to guess in the comments you know, I appreciate it, but I delete those immediately. Those are actually the only comments that I delete I'll keep criticism in there all day long, but if I see comments right or wrong trying to guess restaurants, I instantly delete them.

So if you can try to remember to keep the restaurant names or the business names or whatever out of the comments, I know that there's other texts out here that watch these and they know where I'm working. You can tell if you're a service tech that works in the restaurants you and you work in the same ones. You'll know there's little things that you can tell, and you know I appreciate the guys that do try to keep that out. Okay, all right um.

So I had a very interesting video that I released yesterday and I'm gon na get to that here in just a few minutes. But I do want to start to talk about something and I'm going to go ahead and answer a question that came through right now from HVAC kid and he asked why do people hate Danfoss TX V's? What makes them inferior to sport'ln and I'm gon na tell you personally why I don't care for Danfoss TX, vs or expansion valves? Okay, I just don't like the way that they were designed, and one of the things that I really don't like about their valves is the stainless steel design, the little peanut style, they're super small okay, at least the ones that I come across. Most of the time. They're not adjustable, I know some of them are, but majority of them are not adjustable and they had a history a long time ago of and I'm not gon na, say that it's the same now, but they had a history of basically just going crazy and not Taking adjustments when I was coming up in the trade, I you know the little Danfoss peanut valves, we call them man, those things were they just, they seemed like they were all over the place and we could never control super heat.

It was just always a nightmare. Now I will say to to Dan fauces defense, not that I'm gon na start using their products but to their defense. When I was coming up in the trade we weren't following proper refrigeration practices. Okay, but to the to the same thing, though, I have always liked spoiling products.

They are sponsored on my youtube videos, but guys you notice, I don't have any other sponsors and that's because I believe in what spoilin makes and I believe in their products, because I've always used them. Okay, and in no way does Portland tell me I have to do something or anything like that. Okay, so it's not because I'm biased all right. I've always used sport'land products.

So that's why it's always fit. I've always been a fan of their dryers and their sight. Glasses and I just haven't been a fan of danfoss, but I don't talk crap about them all right. I usually don't address that too much.

I might say you know hey. I don't like this emerson valve or whatever, but I you know I try to keep the negativity out, but there is a general hate in the HVAC trade. You know industry in the United States for Danfoss products. It's a pretty well-known thing that a lot of people don't like their stuff.

You know, I don't know what other people's reasons are, but I've just never had a good experience with them, so you know to each their own. I know that they're, a huge company around the world and they're very popular. You know - and I know that spoilin is not as popular in other countries, but you know here I just really like the spoilin product. So that's my two cents on that.

Let me see definitely got a lot of questions coming through here. Okay, let me see what we got. Have I ever trained. Anybody that is completely green, does not even know the basic hand tools.

Yes, yes, I have now it came from Rocky, so yeah. I definitely have done that. It has worked out. You know I mean I don't still have the people working for us, but we've brought people up.

Basically, we hired them off of their people, skills and their ability to other mechanical skills. Basically, you know they had nothing to do with HVAC and two of my best employees ever had nothing to do with HVAC when they came to work for us, and you know we train them and they moved up and they moved on. You know that happens. Life happens and they move on, but they were two of my best technicians ever you know so, yes, we did teach them from the ground up.

Sometimes I think that's a better way because you get to train someone the way that you want them to be. I'm really saying I'm a lot, so I got to work on those crutch words but yeah. So you know it's um. So there we go again see you got it's a drinking game guys.

Every time I say, um take a drink. Okay, let's see you guys will be drunk really fast all right. Let me see what else we got going here and there we go again. Um, I'm trying to understand this question.

I don't really understand your question Ramon. If you want to give me some more context, I'll definitely try to get to that. Okay, let me see what else we got do. I treat apprentices that have more knowledge than Oh.

How do i, how do I treat apprentices that have more knowledge than a newer apprentice? I mean it's all the same dude. Thank you very much for that super chat, Isaiah. That was really nice of you bud. Thank you very much.

Okay. I'm gon na I'm gon na have to I'm gon na stop yeah. This is this whole own thing is getting ridiculous. It's distracting me so, but no, I don't treat apprentices any different.

Okay, I don't treat. I try to treat all my employees the same way. Okay. Try not to get Jeff dude, that's awesome.

Thank you very much for that super chat Isaiah. Another super chat. Thank you very much man. You guys are awesome.

Thank you. Thank you. Could I make a video for tips and tricks online, set running bending, ACR, etc? Sure you know one of the things that you guys have to understand with my videos is. I definitely would love to make a video with line set tips.

I actually have quite a few videos where I'm talking about bending, copper and different things like that. I don't know if I have a full to tilt tutorial on it, but it also gets difficult when I have so many videos, I think there's two hundred plus videos on there, and so I know that YouTube doesn't have the best way of organizing those videos. So it does make it a little difficult. That's always something I've wanted to try to work on is organizing somehow I've thought about creating a website and cataloging the videos on there.

So then that way people can search them. You know and then have links to YouTube or something like that. You know that's things that I've always thought about doing you know, speaking to this actually brings me into a segue. Maybe we could do something like that.

Oh no, we can't actually no that wouldn't work on there, but since I'm already going that direction I'll go ahead and mention it that myself and a few other YouTube creators have started a discord server. Okay, this is not my big main discord thing that I have been touting. I still I'm gon na do a private one too, but I've been working on a project with a bunch of other YouTube creators and it is a discord server. There's going to be a link in the show notes of this video guys when that, when the streams over do me a favor go there click that link and you guys can join the discord server.

It's gon na, be myself and, like I said, a bunch of the other YouTube creators that I find myself to be my internet friends, and you know we just kind of go on there and it's kind of a way to continue the chat that goes on in Here, ok, so I'm gon na pause on the questions for a little while guys and I'm gon na go ahead and get to a couple things on my list, because I have some things I want to cover and then we'll get back to the questions and start Addressing them, ok, so um I already covered what my channel is about, but something that I wanted to talk about in and I get this quite a lot. You know I read it in Facebook groups and I want to explain something you know as a business owner. We have a lot of things to think about all right. Not only do we have to worry about the customer, we have to worry about our reputation, we have to worry about liabilities and we have to worry about our employees.

Ok, I don't have this problem with my guys, but I notice a common thread within the social media network within Facebook and even someone instagrammed to and I've baited this question by asking little tidbits and seeing what people think. But when it comes to, you know, for instance, we're gon na use GPS as an example when it comes to adding GPS to our vehicles, all right, the amount of hate and distrust that comes from GPS, ok and or cameras in a vehicle, and I understand I, I get the the push against GPS. I get the push against cameras, different things like that. I personally don't have cameras in my vehicles, but I know some people do and there's a reason.

Why guys? Ok, you have to understand something. We have to think about everything. As a business and something that I don't think people put into context when they really think about this, because I know it feels like you're being invaded upon, I know it feels like they're intruding on you, but something that you have to understand. For me.

I have a fifty to a sixty thousand dollar vehicle rolling down the street, all right, driven by a person that I do trust right, but he's a person all right and what happens if he gets into a car accident. I have so much liability on me. Millions of dollars in lawsuits potentially and yes, we have insurance and every other business should for that reason. But we have to protect our investments.

Ok and when comes to putting something like GPS in a vehicle - and I know that everybody hates if you do have GPS to get that email - you were driving 10 miles an hour over the speed limit. I'm sure it's annoying, but you have to remember something our insurance rates, our liability insurance rates, our auto insurance rates, all that stuff goes up if you get into a car accident. So if we start to notice habitual driving habits that are bad, it starts to raise a risk for us. Okay, and it's not that we don't trust you guys, everybody's human, all right! Everybody speeds.

Everybody forgets to use their blinker. That kind of stuff right. But if you get pulled over so many times and you get a ticket for that, that affects our insurance rates and things like that - okay, so not the GPS is gon na solve all of that, but also GPS is a tool that we use to, and I Know people say nobody uses GPS for a tool, but yes, we do all right. I think we have GPS and it's not in our vehicles.

It's actually in our phones at my company and we've used GPS more than we've ever had. I think we might have looked at GPS, like maybe two or three times and noticed that someone was doing 100 miles an hour in a vehicle. Okay, that's not okay, by the way to be doing a hundred miles an hour in that service vehicle, because the huge liability you create for the company, okay. I know I'm kind of going off on a rant here, but I just got expressed to people that when it comes to, you know things that you think are intruding on your personal space.

It's really not when you think about the fact that you're driving a company vehicle and that that company's on the line, not necessarily you because you know a company has insurance. I can almost guarantee a hell of a lot more insurance than you have on yourself. So when that two million dollar lawsuit or three million dollar lawsuit comes through because you got into an accidental car accident, that wasn't your fault and someone died, guess what you don't have enough money, so they're going to come after the company! So that's why we have to be worried and we have to pay attention to driving habits and different things like that and guys. This is not coming from my company problems.

We don't have these issues right, but I'm just bringing this up because I read this in the Facebook groups and I thought it was just you know. I felt like I needed to address it. Okay, so I'm definitely going to get to some more of the chat and, let's see yeah everything's expensive work vans. You know, I see you know yeah it just you know service in general suspension.

You know it's just it all all happens. Okay, so you know just try to try to take it easy and try to try to think about the business to instead of getting upset about certain things and - and I'm not saying you guys, aren't justified alright, because you know yeah. Sometimes people do feel invaded upon for certain things. I understand the argument of a camera, pointing at you all day.

I get that one that one does sound strange, but there is a justification for that too. I'm not saying that I'm gon na do it, but I'm not saying someone's bad for doing it. Maybe it's just an accident camera. Maybe it's you know for liability reasons or who knows you know so.

Alright, let's see what we got inside here. I know we're missing. Some questions, but I'm gon na definitely try to get to them. Okay, let's see have I ever heard of discharging a capacitor with DC volts on a multimeter Randy.

No, I don't know that I've ever heard of that using a multimeter uh-huh. I I don't know that. I have I mean honestly, I've only heard of people discharging capacitors by shorting them or you know. I've always thought that you could use a multimeter.

I mean I guess that makes sense so Joe. Thank you very much for that super chat. I really appreciate it bud and yeah guys. If you could please hit the like button, it definitely helps out the stream okay.

It really does. Let's see what else we got yeah. That's really awesome all right. Let me see what else I got in here.

What information are criticisms? Would I give to anyone trying to go out on their own Brandon great question Brandon if you're gon na go out on your own good for you, man, right yeah, I'm assuming and again don't take this the wrong way, but I'm assuming that you're a full fledged Service technician - and you know your way around the industry right because that's the best bet to do it all right. If you're going out there and you're not quite confident in what you're doing, I think you might run into some problems. I would HIGHLY highly suggest that you, you take some business classes, all right, there's a lot more to this than just going out there and starting to charge customers all right and another thing again. I am NOT a business person.

Alright, I'm not super smart without stuff, but don't take out tons of debt to start a business guys that gets you into trouble. Alright, I know it's almost impossible to do a completely debt-free business, but if you can do it do not go take out giant giant loans, especially when you're starting? Oh, my gosh, that's so dangerous guys. What happens? I mean we're on the brink of all kinds of financial chaos at any given moment these days. So if you go take out a giant business loan and then the economy, tanks holy moley yeah, it's a gamble, it's kind of like playing the lottery, it might work.

There's a lot of people that it has worked for, but maybe you're gon na be the one guy that it doesn't work for. So again, I am NOT the financial expert or anything, but if I could encourage anybody to do anything is don't go into debt. To start a business be very cautious if you are gon na go into debt. Maybe you have a family member, someone that can help you out, you know, but who man it's very dangerous, taking out business loans and stuff just start a business, but again, okay, all right! Let me see what else what I? What would I expect the average lead installer to be making in Florida at least 5000? That's Smith, I honestly don't know, but I am NOT in the Florida market.

There might be some guys in here, I'm in Southern California, so the economy's totally different out here guys. So alright, let's see have I ever. Let me see alright, so that's it on that one. Let me go ahead and go back to my list and see what else we got alright.

So let's go ahead and talk about this: the elephant in the room right now, my video yesterday, the r2 90 video guys that was a one that I've been working on in talking about for a very long time, Isaiah. Thank you very much for becoming a member of my channel. That was really awesome of you bud, so I released a video and the reason why I made this video. I want to preface this okay, I am I.

I read a lot of comments and different things on social media when are 290 hydrocarbon. Refrigerant are 600 all of those started becoming very popular in the United States. Okay, for those of you that are watching internationally, the hydrocarbon refrigerants kind of just became mainstream in the last five years and they really ramped up in the last two years out here in the United States. So almost all of the reach in DIF, not all of the reach and refrigerators that are being shipped to restaurants.

These days are going to be made with a hydrocarbon refrigerant, all right, whether it be our 600 or our 290. Most of them are our 290. A lot of the our six hundreds are on the domestic residential refrigerators, but in the commercial restaurants, we're seeing our 290 like crazy and a lot of people are afraid of it, and I get it there's some safety practices you have to follow when you're working on Our 290 guys all right the biggest thing, the biggest thing, if anything, is that you purge the system with nitrogen before you do anything all right and remember that our 290 is unauthorized 98 % pure propane. So it's not barbecue propane right, there's no smell to it, because the barbecue crap, that's in the blue, rhino tank in your backyard.

They add a smell to it for safety reasons, but that odorant causes a lot of problems and it's a contaminant. So you don't want that in our refrigeration systems because of the different stuff that's going on in our systems. The refrigerants are changing states and all kinds of things, and that's a chemical that they add to it. So we don't use that it's one thing on the barbecues, because we're just burning that off all right, so this unauthorized propane it can be dangerous in the wrong hands or in certain situations.

So there's certain procedures you have to follow, but it's really not that big of a deal guys it really isn't. I've got a couple videos on it. Just purge with nitrogen. Have a fire extinguisher handy.

You know the really interesting thing. If you don't already know are 290 does not have to be recovered, meaning that you can vent it into the atmosphere legally and that's that's a whole trip too, because we're so used to recovering all of our refrigerant and disposing of it at supply houses right. But our 290, you just event it, but it also does create some issues. Because can you vent it in the restaurant? You have to make sure it's a well ventilated restaurant.

Is there an exhaust fan or something nearby to pull the stuff out so anyways? One of the biggest things that I hear about our 290 is people saying all that stuff's junk it's crap, you shouldn't use it. I just pull it out and put r134a in there and right off the top of the bat. I knew that that wouldn't work alright, because if you, if anybody's ever seen in our 290 system, everything is smaller, it's just not designed for r134a alright. So I know that there's other refrigerants that it might work better, and I know that I could make it work right by tweaking some things by changing the expansion valve by doing stuff like that decrepid plumber.

Thank you very, very much for that super chat, but that is awesome. Thank You bud. So I know that there was things like to my system, but I wanted to pose or to perform the experiment that I've heard everybody and not everybody. But so many people tell me they did and it worked with flying colors and that was to simply remove our 290 and put 134a in the system.

All right. The two gases are totally different: refrigerants right, different pressures, different saturation temperatures totally different, but I went ahead and did that, but to be fair, I made sure that I had a clean and dry system. I made sure there was no propane left in the system. You guys saw by purging it with nitrogen pull the proper evacuation, and then I went ahead and wade in new refrigerant just to be a hundred percent sure that it had the factory charge in it.

And when I did that, I let it run. And then we took some tests, I verified with the the the factory charge of our 290. First, what the vital signs of the system were with the evaporator TD was what the condenser TD was, and I tried to mimic those with 134a and it failed miserably. What ended up happening was in order to get my sub cooling numbers somewhat, where they were.

I think I got it to like eight eight degrees sub. Maybe I think in the other one was close to fifteen or something like that. I my expansion valve basically was non adjustable and it was basically flooding back to my compressor and I had you know very, very low superheat at the compressor which was causing the compressor to not work correctly, which inevitably caused the system to not work correctly to so. I basically followed what I thought anybody else would do you know just by winging it and seeing what would happen and the experiment failed.

I will say that I know that if I took some refrigerant out that it might work half-ass alright, but it wouldn't work properly, and that was the point I was trying to make guys is that yes, I I can make almost anything work. If you take some gas out, you tweak it and those numbers. Look. Okay and you know it's kind of working, but it's half-ass all right and I'm not judging you guys.

I know some of you have done the experiment, but I mean plain and simple as a business owner, I can't have my technicians out there re-engineering refrigerators when I'm going to be the one to go out and have to financially warranty that equipment when a compressor fails Because it's flooded back and there's no oil left in it and then guess what, when you wash oil out of a compressor and it goes into the condenser of the evaporator, how do you get that oil back? Is the technician gon na know the oil is gone or is he just gon na go in and change the compressor and put a new compressor in and now we have double the oil charge in that system and then maybe that'll come back, but guess what? If all that oil comes back and makes it into that compressor again, then the compressor is gon na have too much oil and it's gon na fail. How many times do you think this process is gon na go so that was the point I was trying to prove all right again. I know our 22 would have been a better choice. 407, a would have been a better choice, all these different refrigerants or if I would have taken the expansion out and put in a new expansion valve.

The whole point that I was trying to make was that, if you simply dropped in 134 a it would not work all right, and I kind of explained some things in the video too. I was thinking about something I was trying to think about the the arguments that I might get all right and again. I know I see comments coming through. I haven't really gotten to them yet, but I will look back and we'll get into them.

Okay, I know that I was trying to anticipate arguments all right and I was the the one argument I thought in my head that someone might might raise is well you're using alternative refrigerants for r22. So why not use an alternative refrigerant for Archon 90? Well, in fact, actually I don't use any alternative refrigerants for our 22. So again that was my argument that I made up at my head. Nobody said it to me, but I do realize that there is alternative refrigerants for r22 and that's because it's being phased out all right, our our 290 is not being phased out.

I also saw an interesting argument, and this was a good one actually, and I in this one had merit, and it was from someone saying you know I work in I want to say he might have said Chicago or something he worked in a big city where He works in a lot of high-rise buildings and he just thought it was a liability. You know to have flammable refrigerants in the region. I get it, but you know what yes. I guess I see some of the argument there, but first let's say something right: what do you need to have a fire? You need oxygen, you need a spark and you need fuel okay.

So a compressor is not gon na magically get the perfect amount of oxygen and the perfect amount of fuel in it and have a spark all at the same time, because it's a sealed system, even if the compressor had an internal ground there. Theoretically, if all proper refrigeration practices were followed, there's no oxygen inside that system. It's not gon na combust and explode right now. If someone doesn't follow proper refrigeration practices, yeah sure some weird crap can happen.

Okay now I can maybe see a terminal vent. Alright, if you have a terminal vent, then you have flammable vapor and hot oil blowing out I've seen a flame come out of a compressor. That's just four! Oh four, eight on a terminal vent. It happens.

Alright. Thank you very much for that super chat. Hasim. I don't know how to pronounce your, but your name bud, but thank you very much so I have seen a terminal vent on a non flammable gas.

So yes, I do agree, that's an interesting argument, but I will say, for the most part: compressors typically don't have terminal vents. Okay, proper preventative maintenance can prevent overheating issues can prevent dirty oil and different things like that. Another thing to think about too: it's not us. That's choosing to use these flammable refrigerants right, we're just doing what we're told by Big Brother by the government by whoever decided to make these global warming police the hippies, whatever right, I'm not really gon na fight it as a business owner.

It is what it is. It sucks yeah, we got to jump through extra hoops, but guess what we're getting paid for it, we're making money right, I'm billing for my time. So it is what it is. That's the way I see it, that's the way.

I approach it. Okay, but I'm not trying to say that you're, stupid or you're wrong if you think that you know blah blah blah blah blah, I'm just saying these are my opinions, guys all right all right. Let's see what I'm missing in here see what questions I've missed and I definitely have some more things I want to cover, but I'll get to these right now. Let me see: okay, okay, so this is all addressed this one right now to Isaiah.

You asked me this one, you said: can I do a 134a to 407 F conversion? Okay, so - and I actually got that a bunch people saying you know what it'd be an interesting experiment to see you doing this or doing that and okay, I like doing those experiments and they're fun and honestly I might try to do one of those experiments. But what I don't want to do is I don't want to ever encourage someone to try to experiment with things and potentially cause damage. One thing I will tell you is: I will never ever for liability reasons, put our 290 in a system that was not designed for our 290. I've had people ask me that so many times in the last two days.

Why don't you? Why don't you? I would like to see an experiment where I take our 22 out and put our 290 and oh hell? No! Okay! Not until someone tells me. I can't because there's too much liability on my side to do something like that and Isaiah. You know I might do that, but - and I was starting to address this earlier to - is my videos really aren't for the most part - things that I can plan. I mean this was an interesting one because it just so happened that I got a refrigerator and I'll explain that story right now too, but you know I don't really go out there.

Thinking, okay, I'm gon na go to this restaurant and I'm gon na make a video on this. Today I mean it kind of just falls in my lap. I get a service call. I turn on my camera and I start talking alright, that's kind of how my videos are formed so to explain the question that I got a bunch of times.

How did I get that region right? It's a brand new refrigerator. Why did the customer throw it away? It's a $ 4,000 refrigerator. Why did they throw it in the trash and I'm gon na tell you when you deal with corporations it's kind of funny, but corporate money, corporate finance is kind of silly. It was easier for that person or the the the person at the company that ordered that refrigerator to have me, throw it away than to do the paperwork for the mistake that they made and that's how corporate money works.

Sometimes it's not something I'm gon na sell. You know I can't do that that I can't in good conscience, turn around and try to sell that refrigerator, alright, because they purposely asked me to dispose of it. It I'm not gon na benefit from their mistake, but in a situation like this, I can experiment on it. Heck yeah, alright or I can donate it to a school or something like that heck yeah, but I can't turn around and sell it.

I'm not gon na. Try to profit off at someone's mistake like that. No it's too much of a liability, and you know if the customer caught wind of me trying to sell the refrigerator. You know that's just not good, it's not worth it but yeah.

It is interesting how corporate finance works. You know someone made a mistake and then, by the time, a new break it down, they sent the refrigerator there. By the time we got someone to repackage it back up because it's not it was on a pallet, and you know it was all shrink-wrapped and taped and all kinds of weird crap by the time you got that package back up, then getting it back to them. It would probably cost more than it cost to make that thing to ship it back.

That's another thing: I've had manufacturers mistakenly send the wrong equipment and they'll just tell you to throw it away hell. I even had a Linux air-conditioner, one time, a seven and a half ton Linux, air conditioner that was accidentally shipped to us with no heat. It was basically a straight cool Linux packaged unit and we ordered a gas heat model. They told us to throw it away.

Seven and a half ton Linux package unit - and this was probably in the early 2000 so that just shows you it just wasn't worth the shipping cost to get it all the way back to them, so they'd, rather just get rid of it, so funny how that Stuff works all right and let me see what I'm missing in here. What made me get into HVAC! That's a good question, so my father, my father's done air conditioning and refrigeration. Since I was a little kid, I grew up in the trade and I decided to come work for him. One day it took a couple years: Jeff dude, you're, awesome man really really appreciate it, but all right.

Let me see what else I got in here. Do I have any other videos dissecting units like that, delfield, no, not yet storm, but that is something I can definitely do that a little bit more. When I come across an interesting reach and refrigerator, because with some of the restaurant chains, we work for, we probably installed two to three regions a week, so we're throwing things away left and right. So if I come across another interesting one sure I'll dissect it, but no that was the first time I ever dissected and that was from a couple weeks ago, I'd dissected, a delfield region that I was very curious about how it was made.

And I you know it's funny, because I have probably bout six compressors on the side of my house two that I brought home with me that I want to dissect. You know - and I think I've showed these a million times, but I have a bunch of spoilin valves that I decided to dissect with my bandsaw, so I can see how they work and took them apart. I probably showed these a trillion times, but a head pressure, control valve and different things like that. I got all kinds of stuff, so we'll definitely try to show some of that a little bit more for sure.

Let me see what else I got on my list. All right any new videos on the new channel, oh great question, so I am working on a new YouTube channel guys I there's a nightbot or my moderator, bot or whatever it keeps posting a link or if it hasn't already, I'm sure it will about a new Channel called HVAC our tools. I have not released a video yet, but I had they are coming very soon. I am working on I'm I told you guys.

I would do it the first of the year. They should be here any time still working on them, but I wanted to get those are 290 video done. First, the first couple videos is gon na, be I've been reviewing thermal imaging cameras, so I've got three thermal imaging cameras that I purchased and I've been using. So I'll be doing a video on that and then the next video or one of the two videos that I'll release and then the next one will be a video on some work pants.

I took kind of a poll and had been asking in the facebook groups about the most popular types of work pants and what people liked. And I was just curious because I wanted to change. And so I ordered probably five or six of the most popular brands of work pants, and I tried them out for, like between all the pants. I've been doing a test for about six months, and I came to a clear winner and I'll talk about those two and the things that I like and dislike, and it's gon na be things like that where I think that, like I'm, just gon na share my Knowledge, it's not gon na be like people are sending me tools every day and I'm doing reviews on my.

I just want to do it my way it's gon na be kind of my style of stuff, so that'll be coming soon. I talked about it earlier I'll talk about it again. We started a discord, server myself and a bunch of other YouTube creators there'll, be a link in the show notes of this video for that discord. Server it'll be like the chat.

That's going on right now. You guys will be able to come over and we'll be able to talk just like we're talking in the chat you'll be able to have access to myself and a bunch of other YouTube creators. So please come check it out. It's free! It's not anything that cost! You any money or anything like that, so it'll just be a place where we can all sit and talk and you know be able to communicate, and you guys can ask questions.

So let me see what else I got in here. Am I going to need the mana talk, advanced factory training in February? No, I am NOT. I've always wanted to go to the advanced factory training. I've never done it, but no.

I will not be doing that because I'm going to the HR show it kind of limits me on on being able to do anything else in February, because I'm already gon na be taking a week off at the end of January, beginning of February, and also I Really really wish. I could make it to the HVAC educators conference in Vegas this year too, but that one's awfully close to the HR show. So I don't know if I'll make that one either, but that one's probably if I had to choose anything between HR and the HVAC educators conference I both want to go to. I want to go to both of those so bad.

So all right, let me get to my list here and see what else we got. I a million times - and I kind of covered this already, but in the Archon 90 video, where I converted to 134a, I do want to make it clear that that system had a non-adjustable R 290 me expansion valve, so it was not fixed orifice. So that's why I couldn't adjust the valve and make it work better or anything, a great question that I had just before the stream and it was relating to an older video. But I talk about this.

All the time is how, in the heck, can I tell what the liquid level is in a receiver tank when it's sealed and that's a really good question, but it's pretty simple. All that I do is I pump the receiver down. So I trap the refrigerant on the the king valve between the king valve of the receiver and between the discharge reed in the compressor all right and it's trapped in between those two places. So it's it's usually in the compressor and the condenser, and it stops at the receiver.

Well, when you do that, the refrigerants gon na turn back into a liquid majority of it, and it's gon na fill up that receiver. And so then, if you have a receiver full of liquid, all you have to do is take a heat producing device that doesn't exceed the temperature, the safety limit temperature of the receiver. And if you pass that heat producing device up and down a couple times, you can actually take your fingers on the back of the receiver hold on. So this is a receiver right that I've cut open.

But if you take that heat producing device, you can actually take your fingers and run them, and even though this is a sealed tank, where you feel the temperature change is where the liquid level is because you would have vapor up here and potentially liquid right here. Well, obviously, the vapor is gon na, be a lot hotter and it's gon na take a lot more to boil that liquid off, so you'll usually feel it'll, be cool, cool cool and then it'll get red-hot. There's your liquid level. That's all you got to do to find the liquid level on a receiver all right all right.

Let's see what else I got on my list here to talk about. When will I do another Saturday live stream? That's a good question. I don't know, I really don't have any plans to do it right now, but you know the whole point of the discord server is is, maybe people can have access on there because we can do audio chats and different things like that, but maybe we'll do another Stream, it just depends. I definitely need some more organization, I kind of winged that Saturday live stream, that I did a while back, and I definitely want to try to find a way to organize that a little bit better.

So alright great question I had from someone in emails actually - and he was asking me about when doing a leak check on a refrigeration system. If there was any tips that I had to find leaks better, and I do. I have lots of interesting tips to help people to find refrigerant leaks better. The biggest thing I can tell you is first off all of the equipment needs to be turned off right.

Condensing unit turned off evaporator fan motors turned off, don't be trying to leak check with an electronic leak detector with the evaporator fan motors off. All right, excuse me, with my coke nose, starting to itch with the evaporator fan motors, turned off all right and then the next thing that I'm gon na do make sure that the system was calling before you turned it off right, and so what happens? If you have a walk-in cooler, that's a remote system, the compressors on the roof, and you go to do a leak check on it, but it was pumped down if it was pumped down. Then that means the refrigerant was stopped behind the king valve on the receiver or behind a valve somewhere in the liquid line, a solenoid valve or something. And if that's the case, then you're gon na have an extremely low pressure in the suction line.

So if the system is pumped down, what I suggest you do is obviously turn the system off and open up your gauges, the high side on the low side and let the pressures equalize between the high side and the low side. What you will do is you will build up equal pressure on both sides of the system, and then you can do a better leak check now, if that pressures not enough, then sometimes what we'll have to do is remove all the refrigerant from the system put a Tracer amount of refrigerant, usually you know whatever refrigerant, you have a tracer amount and then bump it up with nitrogen, that's another, but that's a last-ditch effort, because that requires a lot of effort of changing filter, dryers and different things like that. Okay, but yeah. Definitely turning the system off making sure all the evaporator fan motors are off make sure all the condenser fan motors are off.

Let the system sit equalize, the gauges I'll. Let the pressure sit there for a little while then hate it with your electronic leak detector. I'm not a fan of attacking and looking for a leak with just soap bubbles guys grab an electronic leak detector, all right, they're, cheap enough. Now you can find all kinds of different brands.

I use Adi tech. Select, it's not the most expensive leak detector, but it's certainly not the cheapest, but it is a great leak. Detector. I've used Adi tech select for at least easy 10 years, at least not the same one, but I mean you know they're great leak detectors.

I would love to get my hands on the D Tech Stratos. It looks really cool. The the verdict is out on how awesome it is, but I do know that my buddy Ruben has the info conde, Tech Stratos. Whatever thing Ruben, how are you liking that, whatever that thing's infocon Stratus or whatever it's called, I don't know why I just had brain part, but I know I saw post what you use in it or something.

So I have an ultrasonic leak detector right. I've actually been reviewing one. I borrowed one from someone and I've been trying it out. The verdict is not out on the ultrasonic, yet I definitely see a use for it.

But again, I'm not gon na spoil the beans on that one yet, but I have used them before, but I do not suggest okay guys, there's nothing worse. When I hear someone, that's just gon na attack a leak with just soap bubbles. Oh, my gosh you're gon na be there for hours trying to find a leak with soap bubbles. Only okay, please please, please what I do is I start with an electronic leak detector.

When I start picking up hits, then I hit it with the big blue leak. Detector, fluid soap bubble stuff in the spray bottle, make sure the stream is bubble three sprayed on there and let it sit and you'll find the leak but use the electronic to narrow down the leak or use an ultrasonic or whatever. Okay, let me see what else right on yeah Reuben says that the detects stratus there you go. I don't know why I couldn't think of that, but the D Tech Stratos is was really cool.

So that's awesome. I like it. I like that, the cool appeal of the D Tech Stratasys that has the PPM readout on it. So it can tell you when you're like, if you're, using an electronic like the D tech select, you walk into a walk-in and it goes crazy and you're like okay and then you have to wait for it to zero out and then it goes crazy again.

And it's like: oh my gosh, this leak is so big. You know with the with the one with the ppm readout out of the parts-per-million readout. Theoretically, you can look at it and say: okay, it's getting bigger. As I get closer, it's getting bigger and bigger.

It's not just an audible, sound, it's a it's a numerical readout. So that's an awesome selling point of you know a ppm readout on it all right. Let me see what else I have. I already covered that already covered that I'm making sure I'm going through my list of different things.

I covered this and I want to stress it again guys just because you're working on our 290 refrigerant - it's not gon na blow up, but you still need to follow some safety practices. Okay, I have showed in several videos where I had an AR 290 system and I was changing a compressor on it and I removed the compressor. It had been sitting out of the system for 10-15 minutes and I think I even purged nitrogen. If I remember right through the system and then I went to go Bryce and I took my torch and I took it by one of the lines and there was still flammable vapors in there that lit there - wasn't nitrogen in it at the time.

But I had purged it with nitrogen, but still there was flammable vapors in there. So remember that, though, the the refrigerant vapors will get stuck in little pockets of oil all over the place. So the biggest thing when working with our 290 is purging your systems properly. Okay, alright, let me see what we have in far as questions go.

What is the valve under the voltmeter? Oh I'm gon na tell you right now. I have no flippin idea. What that thing is hold on just sight. This yeah, I'm not even gon na start talking about this Portland sent it to me.

It's it's a supermarket valve. I do not even have the slightest bit of idea. I'm sure you guys in the chat can tell me I don't use this. It's a oh! It's a hot cast bypass valve huh yeah, it's a sh G B II.

Oh no, it's a discharge bypass valve! That's what it is yeah but yeah. I don't use the spoilin sent it to me to cut it open. I just haven't cut it open. Yet so yeah beyond me, don't work on these at all.

So let me see what we got in here, all right cool. We got that all right, I'm gon na go and get some more. You guys the stuff in the chat. So do me a favor put the questions in caps lock and we're gon na start attacking those right now: okay, what is the oldest rtu unit? I have worked on the oldest air conditioning system that I worked on was probably I can remember it.

It was a unit that I removed. It was from 1964. If I remember right, because I think it was the year my dad was born so as 1964. I think I removed it about 15 years ago.

It lasted for many many years. It's very sad that we can't install an air conditioner today, that's gon na last 30-plus years, there's no way in heck. You know it's just sad. The way they make equipment, but yeah that was probably it was a 1960s unit was the oldest thing.

I've ever worked on, so let me see what else we got in here. I really appreciate all the nice comments I see in there guys, and you know something to understand too guys. I try to get to all you guys's comments that you leave in YouTube and Facebook, but it's like it's so overwhelming. There's so many comments, so I'm not trying to be rude.

If I don't get to you guys's comments, that's why it's best. If you guys have questions, send them in an email, it's best to get emails for sure my email is HVAC. Our videos at gmail.com, the stream labs bot, should be posting it. It's in the show notes of this video and guys there's always super valuable information in the show notes on my videos, always always go check out the show notes, there's always good stuff.

Inside there I usually put two links and all kinds of stuff. You know ways to help me out. You know you guys don't have to super chat. You don't have to do anything.

There's affiliate links in the bottom of my videos like Amazon links, all you got to do is click one of those links, even if you don't buy the tool buy something else from Amazon. I get credit for like the next 24 hours. If you just click. My link, it doesn't cost you anything extra and it does support the channel too, so that definitely helps let's see what else difference in restaurant and supermarket refrigeration.

What is the difference? I'm assuming as your question that I mean it's the size of the equipment.
