Ah, 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. How are you guys doing this evening? Hopefully you guys are doing well.

Let's start this off with a little introduction. I've been doing this a little bit more recently because we have a lot of new viewers on the channel, so my name is Chris. I'm an HVAC are service technician here in Southern California. I started making these YouTube videos for my own service technicians.

It was kind of a training aid quickly decided to make them public, and that was about a year and a half ago and everything just kind of grew from there, and this became what it is. So I started doing these live streams as a way to consolidate the questions, because out of the hundreds of emails and comments - and you know, Facebook comments and posts and different things that I get a lot of the questions are repetitive, some of them. I I don't necessarily get a chance to answer. I do make an effort to go through and read every single comment that I can get my eyes on.

That's why, if you notice, if you pay attention to any of the YouTube comments, I'll usually give them a thumbs up and a heart to acknowledge that I've read the comments, sometimes I'll respond to them. If not, I usually respond to them on these live streams, so especially the questions that I think could benefit everybody, because a lot of them may be repetitive questions and it's a little difficult for me to answer them all. I never anticipated these live streams or these YouTube videos. Turning into this machine that has turned into when I first started my channel a year and a half ago, I think it was a year and a half ago, yeah 27 yeah, so anyways.

When I first started the channel, I never realized that it was going to turn into this thing and it actually has become a second job. I don't want it to be a second job. I never anticipated it doing what it did. Don't get me wrong.

I do make some revenue from these videos, but in all honesty I need to put my family first. So the comments it's a little difficult to get to them all. In the very beginning, I was making three videos a week. I've tailored it down to one to two videos a week and then I still do a live stream every week, but I try as hard as I can to get your guys's stuff.

Okay, I want to make it clear, though, that you know these videos they're really geared towards my own service technicians, and I I try to taillow them towards you guys too, but I also got to remember that these initially are for my own service technicians. I have my own small commercial refrigeration business that does 99 % restaurant refrigeration and air conditioning work here in Southern California, and these are a training aid. Okay, you know what kind of convinced me to make them a training aid, for everybody was just to share the little bit of knowledge that I have. I do not know everything, there's tons of other people that know much more than I they just don't necessarily have a platform.

I encourage everybody out there to share your knowledge, hiding your knowledge, in my opinion, there's nothing good about it. You're not gon na lose your job you're not gon na be replaced. I promise you, unless you suck. In that case, you more than likely aren't gon na have a lot of knowledge.

I mean you know our jobs are so we're in such need for service technicians right now. We need all the help we can get. So a lot of people have been starting up YouTube channels. Lately great go for it.

We you know, I need more help. We need more people sharing knowledge. You know I do commercial refrigeration is and air conditioning. As far as restaurants go you may do something different.

We have guys that do residential. We have guys that do industrial. We have guys that do commercial refrigeration, supermarkets, stuff, I mean share the knowledge guys right now we are lacking, there's there's two or three really good, supermarket refrigeration channels. We need more, you know my buddy rookie refrigeration Ruben is in here he has a supermarket refrigeration channel, but you know there's do we need more? We need a lot more.

So do me a favor if you guys have that knowledge. Consider sharing it. Okay feel free to reach out to me, I'm always willing to share. You know any information that I have about how to launch a channel or anything like that.

I will say you know you need to you need to have thick skin and if you don't talk correctly, if you don't say the correct terms that the comments are gon na eat, you alive so be prepared for that. Okay, I try to be as open and honest as possible so now that we're done with the introduction. Last last but not least, I want to make it clear to that. I have a sponsor on my channel.

My sponsor is Portland. Please go supports. Portland, okay, go check out, their website buy their products. Spoilin is the the best sponsor because they they're they're, not a demanding sponsor.

You know they. They make good products, they don't make snake oils or weird additives and crap like that. I can stand behind them and they're good, because they're not trying to control me they're, not trying to take over my channel there's lots of people, horror stories that I've heard of other content creators that you know get themselves into a position where they feel like they Owe everything to the sponsors and they have to do everything they have to push different additives or whatever so be it? That's not my channel. I don't plan on ever doing that.

I'm gon na do these my way so yeah, that's it! Okay! Um! I got a couple things I want to talk about. I definitely want to get to the chat to my moderator Justin's in here right now, he's going to help me to keep an eye on the chat, because sometimes I can get a little bit out of hand if you guys have questions and you'd like me. To answer them, please put them in caps lock that way, we can try to see them, and if I don't answer your question right away, feel free to put it again. Okay, if I'm not gon na answer your question, I'll, usually say: hey, I'm not gon.

Na answer your question right now: okay, so just keep putting it in there until I answer it. Okay or one of the other moderators tells you to stop all right, so yeah just put them in caps lock. That helps me get to them. Okay, um! So I'm gon na go ahead and start talking real quick on my little list of stuff and then I'll pay attention to the chat as best as possible.

Okay, oh one, the air conditioning guy. Thank you very much. I really appreciate that super chat, so Juan asked me. Could I ask everyone if they balance their own forced air unit blower wheels? I don't know I mean in the chat you guys can answer that.

I don't balance my own blower wheels. If a blower wheel is out of balance, it's time to go, get another one they're cheap enough for me, swap them out, I'm not into balancing a mile. That's just not my style! So be it! It's never been a very easy thing for me to do, but you know hey, maybe the chat will say otherwise. So well right.

Also, there's going to be a movie quote in here this one's a late 80s movie quote. So, let's see, if you guys can get this one, I tried to keep some of the more popular quotes out of the movie out of here. So you know, try not to be a punk and go google it to try to see if you guys can actually guess what the movie is. It'll come in in about 28 minutes, so right on, okay, so um really good question that I had or actually let's talk about the video.

So the video that I did this last week was on a walk-in freezer door that wouldn't shut okay. The customer complained that it wouldn't shut. What I ended up finding was that the door heater had failed, causing ice all around the door. Okay, a lot of people commented hey, I didn't even know there was heaters and those walk-in freezer doors.

Well, there has to be some sort of a heat device, because the point at which it's not a freezer anymore, the other side of the door, is gon na be a lot warmer. Therefore, you're gon na end up freezing that door shut and that's gon na be a problem, so we have to have a MOLLE on heater or a door heater around the door perimeter or the door frame. It usually keeps the gasket nice and warm so that way. The gasket can act as the door seal oftentimes.

There might be two heaters in the door, there might be one in the doorframe and then there might be one in the door sweep okay. In my situation, it just had a bad door. Heater door heaters are not my favorite thing to do and if any of you guys have ever changed a door heat around a walk-in freezer, you probably know what I'm talking about door heaters are probably the worst thing to do when you're working on a walk-in freezer, Because you're in there, especially in my situation, I was in the walk-in cooler all day, so it's 38 degrees, I'm in a jacket. I've got the door open, so the negative 10 degree air from the walk-in freezers.

You know basically freezing my butt off. I was fighting a cold at that, but I mean that's life. You just got to do what you got to do, but you know the walk-in freezer door heaters. You've got to be so meticulous about the way that you do them and if you don't follow all the proper procedures, then it comes back and bites you in the ass, meaning that if you, when you're all done, if you snap the cover on and you you've Spent six hours putting this door heater on and then the cover severs the heater.

Well, you got to start all over now and not only do you have to start all over, you probably got to order a heater and come back two days later, remove all the ice again and go through it all. Okay, I've done enough of these and I've screwed enough of them up that. I'm very meticulous and - and I take my time doing them properly - whenever I change a walk-in freezer door - heater I'd, say 99.9 percent of the time gon na change the hinges the door closure. If the gasket, if it's bad but the hinges and the door closure for sure, in my opinion, the way that the walk-in freezer doors work, especially if they have ice buildup, the customer is still trying to shut that door and they're trying to shut it on ice.

So something's got to give usually the door won't Bend. Usually what happens is the hinges get damaged, but occasionally I've seen the doors buckle to because someone's been closing it on ice for too long. But in my opinion, that hinges usually become weak and, in you know, sooner than later, they're gon na fail. So, as part of the replacement, I usually put new hinges on there too, one of the biggest things about doing a walk-in freezer door, though you got to be very careful about, is the threshold, and I showed in my video that once you pull the threshold up And you pull up all the metal, you actually find that there's a crap ton of ice underneath that threshold and if you don't get all that, I sell that ice is gon na refreeze, okay and then lift it up.

And then, on top of that, you got to melt all the ice and get rid of all the moisture all around the doorframe, because the entire time you're working on it that water will start dripping on your head and pissing you off, there's nothing worse than that. So again, it's a meticulous thing. The tools that I usually use is a vacuum map, gas, torch, dead, blow hammer and patience a cutting wheel. If I need to cut the tracks in my situation in this one, I only had to notch out the track at the bottom.

The tops the the mitered edges were already cut because I use the OEM parts. Okay, so yeah, I think, I'm sure I'll cover some more as we go on down the list. I'm gon na look at the chat and see if there's anything that I'm missing yet and then and I'll see what I can get to hear um. Let me see how come that freezer didn't have a floor.

Prime time, you know it's actually very common out here that it'll usually be 50/50, that we have a freezer without a floor or a freezer. With a raised floor, I actually prefer the freezers without a floor. So when they poured that pad, they actually poured. I think it's like a six or a eight inch pad where the freezer lays so there's plenty of concrete there to insulate it from the outside.

But it's very important that you can't just set a walk-in freezer on a really thin pad because, depending on your outdoor ambient, especially here in Southern California, where it gets really warm, you know that the heat will come up into the box from underneath a slab. So the other alternative like primetime was mentioning was that we have a raised floor, so it's usually a six inch insulated floor that sits on top of a thin concrete pad. The problem with the insulated floor is, in my opinion, is, is that when people defrost The Walking coils, if they don't, do it very slowly and very carefully? If you get water on the floor and it's raised that water is gon na, go underneath the floor and then it's gon na refreeze and lift up the floor and buckle it. That's why it's so important when you're working on a walk-in freezer defrost in an evaporator coil.

Even if you don't have a raised floor, you don't ever want to get water on the floor. If you don't have a raised floor and you just have concrete, the water will freeze on the tile and then it'll be almost impossible to get up. It's just a nightmare. It becomes a giant ice-skating rink, so just be very careful but yeah.

We have a more they're raised floors. We have more they're, not it's just an extra thick pad. So all right, let me see any questions that I miss just keep throwing them down on the bottom. Okay, Taylor: you said you just applied for an HVAC apprenticeship, any tips going forward Taylor when and if you do get your apprenticeship, which you will okay, because we all need help as long as you're, a good tech, and you have a good head on your shoulders.

You're gon na get a job, just keep your head straight. You know no one to keep your mouth shut, no one to open your mouth, no one to ask questions, and no one not to ask questions. The biggest tip of advice I can give for an apprentice is try to figure out what you're your mentor or your you know. Whoever you're working with is gon na.

Ask of you, especially when it comes to tools and predict what he's gon na ask for you and have it ready. So, for instance, if you're changing a compressor - and you know he's gon na, ask you to go, get the torches in the vacuum pump. Have it ready before he even asks you, okay, try to anticipate that stuff, you know and and while you're on the roof. I say this all the time.

Take pictures of every piece of equipments model number. Even if it's stuff, you don't work on, take pictures of the equipment when you get off work, that's when the real work starts. You go home and you start researching downloading manuals reading about equipment. So that way, when you're working with your mentor, you know - and he tells you about stuff - you could say hey.

You know what I read about that and I was curious about this. You know so feel free to send me an email, HVAC, our videos at gmail, and I can try to give you some more information about that. Okay, all right, wow that that uh movie quote came in a lot faster than I thought, huh all right. Let's see what else uh uh see what I'm missing all right.

I don't see anything else in here right now, so he had dizzle got it really quick Nightmare on Elm Street. That's right! So yeah great me and that's the 80s version Nightmare on Elm Street. Okay, not saying I don't appreciate the 2010 version, but the 80s version was so much better. It was just a great movie, but the 2010 version yeah that was cool.

You know you got some explanation as to why Freddy was who he was and what happened so that was kind of cool, but all right, let's see what else? Who does my hair? Who does my hair? I don't know me yeah. It's actually time that I shaved. My head, to be honest with you, so let's see what else we got going on in here, mm-hmm all right. Yes, there you go, keep thinking.

They want you to anticipate what what they want. You know that's the biggest tip of advice. I mean you know. I've got people that work with me and they know you know, hey we're getting to this point and you know I want them to think that, because what you don't realize is the more you anticipate what I'm gon na want.

That just means that you're thinking ahead and you're starting to get into that mindset of a service technician that is is, is you know, thinking of everything you know, I'm a service technician braising in a compressor, I'm not necessarily just thinking about that braze joint! I'm thinking about what I'm gon na do next, you know you know I'm trying to when I go down to my truck, I'm thinking. Okay, what am I done with you know? I take a tool down every time I go down to my truck and then bring a tool back up. There's still gon na be a crap ton of stuff on the roof when you're all finished, but there's one less thing up on the roof makes your job a little bit easier. So you know trying to anticipate what your mentors gon na gon na want is, is actually teaching you and you're gon na learn, and you also learn to be a better service technician too, because as a better service technician, when I go into jobs, I said I Said that wrong, I implied that I was a good service technician but as a service technician, I try to be better every single day and you know I try to anticipate the worst and and even when I go into something you know in my head, I'm thinking.

Okay, what how can this go wrong that way, I can be prepared for it if I'm gon na be brazing wedding here can catch on fire? What happens if I'm unswayed in the compressor, I know you're supposed to cut a compressor out, but life happens. Sometimes you got ta unswept. What happens if I'm on sweating the compressor and the oil flames out? Is there anything that's gon na catch on fire? You know just just thinking ahead, trying to anticipate so alright, let me see what else we got in here. 22-Year old tech keep thinking, and you said you hate when people don't ask if they don't know, I don't know, wait tech here and you hate when people don't ask if they don't know, I don't know what you meant by that.

Keep thinking rephrase that, for me alright, Ernesto says he was taught to think fifteen seconds ahead of the senior text to help them out with to bring tools. That's a great idea. Ernesto is HVAC. Our vlogger he's actually got a YouTube channel too.

So yeah do. I know any channel that does video commercial food equipment. No, I don't know anybody that does the hot side - commercial food equipment, I don't I'm trying to think no, nobody that does it regularly like on a daily. So no not that I can think of right now.

Alright, I'm gon na go and get to my list here so great question. I had someone asked me and I'm paraphrasing and adding to this question, but their question is buried inside here. Our smart devices dumbing down the trade. Actually, this was a youtube comment from someone.

I think kind of criticizing a little bit, but it's okay, it's okay! To criticize me all right, I'm cool with it, but I think it was kind of criticizing in a way saying that you know hey. You know you don't necessarily need all those fancy tools and those digital things to to diagnose. You can do it without those tools, and that is very true. Okay, we don't need iPads tablets, smartphones, we don't need s.

Man, 480 digital gauges, field, piece, Jobling, probes, measure, quick field, piece Apple, it we don't need it. We can do our job with a set of compound gauges, a couple thermocouple pipe clamp temperature devices right and a pressure temperature chart it. We can do our job, but how do we get air flow? Okay, so measure quick can do an estimated air flow calculation. It's not dead-on, but it's better than nothing.

Okay. Measure quick, can do that airflow calculation for us. So it's not that I need measure quick or the field piece app to do my job for me personally, what I use those smart devices and the digital tools, for I see them to be greater to be more accurate, and I see them to consolidate information. For me, so that way I can make an informed decision, so there's nothing better than opening up my tablet.

Looking down at it, seeing my sweet subcooling estimated air flow current draw everything, and then I look at everything and I can see the whole picture right. I'm always preaching big picture. I can see the whole picture and I could say: oh wow yeah. I think this thing has low air flow.

Therefore, look at our superheats really low. You know now in the past. We could do that too, but in the past to diagnose low air flow, we would have to put our service gauges on there. We'd see low superheat, then we'd walk away after we calculated on the pressure temperature chart right mind you.

It wasn't real-time superheat, because we made a calculation in two seconds later it changed and then it changed and then it changed and then it continues to change right as the load changes in the building digital gauges show you that continuous real-time superheat, the estimated airflow that Measure quick gives you saves me hours and hours of duck traversing using an anemometer to measure the air flow to the unit, to prove that I had low air flow because guess what static pressure doesn't tell us true air flow, necessarily okay, static pressure can give us An estimation total external static, but you know the best bet, even even forgetting about measure quick, is to actually measure the air flow. Okay, traversing, the ductwork is a really good method. Using flow hoods flow hoods can also be a little difficult, though, to okay, we're not gon na go into that tangent, I'm not very familiar with flow hoods, but I understand how they work, but there's a whole dynamic of how they can be inaccurate too. But you know digital devices, smart devices, I think they're helping the trade and now I'm gon na go out on a limb right now and say that we as service technicians, diagnose more problems, are more thorough because of smart devices and digital devices.

These days now, yes, there's some people that are lazy and not really thinking and want the apps to diagnose for them. Okay, you're, never going to control that those are the same people that do beer can cold. You know and grab the suction line and say it's low on charge and that kind of stuff, okay, you're, never gon na solve for those people. But we are at the best time, in my opinion, in our careers right now in this industry, because we have so much information at our fingertips: hey guess what we got a problem and we want to know we need help.

We ask the Google we turn on our phone. We message a friend, someone sends an email to me. I'm usually not gon. Na answer the question.

You know someone sends an email to another guy. Someone goes on Facebook in a group and asks people guys it's the best time right now to become a technician and to come up in the trade, because you have so much information at your fingertips. So no, I do not think that smart devices are dumbing down. The trade okay: I think that they're making the trade better.

Okay, let's make the trade great again right. I think that the smart devices are helping our industry all right, rookie refrigeration, I'm gon na ruin. All of you guys ruben asks me who's. My NFL team.

I am NOT into sports whatsoever, I could care less about any sports, don't pay attention, so I probably just lost half my audience. I literally spin. I am. I am so pathetic that I just sit here and hang out with my family watch TV and make HVAC YouTube videos.

That's all I do so. I don't even get to do my own hobbies anymore, which I need to get back into those which my passion is camping, backpacking hiking, that's my passion right there. If I could go disappear well. I just had to put my dog down last summer, but over this last summer, but my dog and I would go disappear into our local mountains for the weekend, just a backpack on my back.

That was the most. That was like the best time in my life. Whenever I would do that because it was just so peaceful, I even took my family to do that. One time where we went backpacking.

That was epic, that's my passion but yeah, I'm not into sports whatsoever. So all right missed any questions, throw them back down in the chat. Okay, guys, let me see all right, I'm gon na go ahead and I'm sure I miss stuff, I'm gon na go ahead and cover some more of my topics, keep throwing them in there guys. Okay, what, if okay so dogs green, is asking me what I always check fan rotation on an exhaust fan? What if it's spinning backwards? If it's a three-phase exhaust fan, then I'm gon na reverse any two legs going to the motor.

If it doesn't have a VFD, you need to be careful about places that you rotate phases, actually no yeah coming out of the VFD. That's where I'm gon na rotate it. If it's a single-phase motor, then usually it has some some rotation taps. But if a single-phase motor is running backwards and nobody's touched it more than likely you're gon na have a motor, that's failing one.

Thank you very much man. I really appreciate that super chairs really awesome that you do that one. So, alright, let's see we're missing, thought on pump out, not recycling pump down thought on pump out non recycling pump down. I don't know what you mean by that total tech.

Are you seeing vent the refrigerant or are you seeing just pump it? I don't know give me some context on that. One total tech - I don't call it and quite know if I understand what you're asking me there all right, how do I clean a rooftop grease trap, a rooftop grease trap on an exhaust fan? I don't I tell them to get the grease cleaners out there, yeah there's special people that do grease. I don't mess with grease, there's people that do it, but I will tell you that here in California and actually I'll cover. This is another question I get all the time, but here in California we're not allowed to wash very much stuff down the drain storm.

Thank you very much man. I really appreciate it. I really really appreciate that. You're, not you're, not asking me stupid questions storm.

Thank you very much for that super chat. Man awesome bud. Thank you all right. Let's see, let me see how do I always have Greek grease traps.

Yeah, the the new Calgon blue coil cleaning crap that takes care grease, really good, but technically in California, you're not supposed to be washing that stuff down the drain. So you got to do what you got to do. Let me see what I'm missing any tips for books to prepare for refrigeration journeyman test Jesse. I don't know, what's gon na, be on your journeyman test.

Okay, I will say that my favorite book, when it comes to refrigeration, is commercial refrigeration by air-conditioning technicians. The really cool thing - and I got a chance to meet dick Wars and talk to him about this book, but I'm gon na tell you guys what I like the most about that book. Okay, is that there is new-school and old-school mixed into that book. There is rules of thumb in that book and there is new, detailed, correct information.

I'm not saying there's incorrect information, but dick Wars does a really good job of explaining things and making them understandable. It is a great great book now whether or not that'll get you past your journeyman test, I don't know I'm sure, there's some required reading to get past your journeyman test. I would highly suggest you do that and not that. Okay.

Alright, let's see what else all right, I'm gon na go ahead and go to why - and this was a silly one, but I'm gon na answer it anyway. So the question was referring to my walk-in freezer with a failed defrost heater. I pointed out about the silent alarm on the walk-in freezer, and someone had asked me: why do they have silent alarms and kitchens? That just seems weird well. The reason why they have silent alarms is because we live in a world where people are and they go and try to rob people okay, so they have a silent alarm in the kitchen.

That's usually hidden yeah strategically located all over the kitchen; they usually have them in the walk-in cooler and the walk-in freezer. The theory is, is that if the building ever gets robbed everybody that's in the kitchen can run into the walk-in cooler latch the door shut from the inside hit the panic button. The panic button usually doesn't sound an audible alarm. It sends code blue to the police and the police know.

There's a robbery happening. They usually come code blue. Ask me how I know and they'll come sometimes with helicopters. They don't come sirens.

They come in in full force with guns drawn and they want to figure out. What's going on, so panic alarms are great in the restaurants. You just have to know as a service technician when you're around them. You have to know what they look like.

So that way, you can have them disarmed and put on tests while you're working on set equipment. Trust me again all right, let me see, have I ever changed an evaporator with a separated grid on a manitoc ice machine. No I've never changed an evaporator with a separated grid on a Manitowoc ice machine. Most of the time if evaporators bad, the customer ends up buying a new machine in my situation, just had a nice somatic machine that had a seperated grid, but the machine was five.

Six years old, so the customer opted to replace it. They ended up putting a new ice-o-matic in there, which I have a few choice - words to say about the new ice-o-matic machine with the new digital circuit board. If you guys don't know, ice-o-matic was the last machine to hold out, they still had all their mechanical controls while they finally went digital. I just installed my first one, and it was a little interesting so anyways the the Manitowoc machines now never had to change a grid on one.

I've had them very dirty before you know how to clean them, but never had to change a grid. Usually, like I said, the customer just changes the whole machine, so you pulled down on one of those alarms, not knowing what it was yeah Ernesto. It's not good, not 5 to 10 minutes yep cop cars outside yep and they were pissed off. I bet I did one in San Bernardino one time inadvertently.

I was changing a walk-in cooler, walk-in freezer door and I didn't even touch the alarm, but just banging on the door ended up setting the alarm off and I was a cocky kid at the time, younger guy and when the manager came in and said you know. There's police outside they want to talk to you. I said no, I'm busy just tell him to come in here, yeah, the sergeant at the time. This was probably in the early 2000s San Bernardino in the city, and the sergeant was not happy at all when he came into the walk-in freezer and told me to step out of the building and had wanted to have a talk with me.

He proceeded to chew my ass out so wow. These super chats guys. Phillip. Thank you very much for that super chat, but that's really awesome.

So yeah panic alarms are not fun. So if I'm missing stuff guys do me a favor, throw it back down in there again, ok - and let me see what I'm missing here all right. So on my list question I had this was on an old video and I've gotten this question so many times guys. So I'm gon na try to describe the video to you.

I had a carrier package unit. It was a tiny little 5 ton carrier package unit. It was actually the one that I had an apprentice brazing with me. Okay, I didn't apprentice working with me at the time and I was letting him braise and everybody was just eating him alive because of his brazing skills, guys.

That was the first time he ever tried brazing. He did a great job. He doesn't work for me anymore, but he was a good apprentice and he was a good hire so but uh in that video we ended up changing a compressor amidst many other things. We ended up pulling the condenser out changing the compressor, because the unit had a cracked discharge line, and I got all these questions in the world.

Why did you change that compressor? Just add oil to it, it would have been fine put refrigerant in. It was noisy guys, I do things for a certain reason. Okay in that situation, the reason why I change that compressor was because, from my experience on this carrier packaged units, I had a compressor that was probably from 2004 alright and it started making a lot of loud noise. It had a crack discharge line.

In my opinion, there was something damaged inside the compressor. Yes, I could have tried to add oil to it and, yes, I could have braised the leek and, yes, it probably would have worked, but for how long? In my experience on Copeland compressors, if they crack coming directly out of the compressor, it usually means that there's something off inside that compressor and it's vibrating, causing that stress point okay. So, yes, I could have put a braze joint on there and it probably would have lasted maybe another year who knows, but guess what I did it and that thing is still running to this day. It's fixed.

I changed the compressor. I did what I thought was best: okay, there's a lot of things that you guys don't see, there's a lot of things that you don't know when I'm doing these videos and there's a lot of reasons that are factors that go into me. Making decisions like that. So it is what it is Joe.

Thank you for that pair. That's jumping and saying you're. My number one fan. Thank you Joe.

I really appreciate that all right, let me see yeah, I don't know what I had balls to say there Ernesto, but I can't remember what I just said. The comments are delayed, so it's like, I don't know what you're responding to, because I honestly can't even remember what I just said: I'm just running my mouth right now. So all right, all right. Let's see what we got going on.

Okay, Kevin Roland's, the the money. These are people donating to my channel. Okay, you can do it via super chats. I do not require anybody to donate to my channel, but I will bring it up.

You know supporting any YouTube channel any content creator out there does definitely help this. Okay help people to continue to do this. We as content creators do get Adsense, meaning that when you guys see a commercial in a YouTube video and you hit that skip button, it's cool. I do the same.

Actually, I don't do it anymore, but I used to do the same thing. In fact, you're actually hurting the Creator because, yes, those commercials suck, but those commercials are the little bit of income that that creator gets okay. So luckily, I don't do these videos for the revenue. The revenue does help I'm not gon na lie, but I do these videos to share my knowledge.

I have a full-time job. I run a service company. These videos are just a little side, hustle that I do. Okay, but as far as the money that you see right, there that's a way that the people that are viewing chose to donate a little bit of cash to me, via whatever they want super chatting or whatever.

So it is what it is, but it is not required. Okay, all right yeah. I would get a call back for sure. Okay, hang on all right.

Let's see, how do I prepare for low temp walk-in freezers? The person was asking me that, because probably said I was cold as hell wearing a beanie. How do you get mentally prepared when you go to work in a walk-in? Freezer first off, I can say, is if you're a refrigeration technician working in restaurants. You can't wait for your company to tell you that you're gon na be working on a walk-in freezer. Today you have to assume the worst, so it doesn't matter if it's a hundred and twenty degrees summer, you need to have proper clothing in your van.

You need to have if you work on warehouse freezers, you need to have gloves beanies, probably a bib, all that fancy stuff dealing with restaurants. In my case, I do fine with the sweatshirt a beanie and just some gloves, but you need to be best prepared. Don't come to work without your jacket. Don't take your jacket out of your van and forget to put it in there, because you're gon na be standing working in a walk-in freezer.

You still got to do the work so make sure that you're prepared for that stuff. So, as far as how you prepare for that, you know it comes with time getting used to it working in a walk-in freezer. I would say that when my apprentice is working with me, he's probably a little bit colder than I am because I don't even pay attention to the fact that I'm cold oftentimes, I'm so focused on what I'm doing I'm in and out of there and I'm knocking It out, usually it's the person. That's watching me, that's getting the coldest so there's nothing.

You know it does suck being the person. That's that's! That's watching, but use that to your advantage right absorb as much information as you can. If you're the apprentice working in a walk-in freezer with your your you know, whatever you want to the person, your mentor, whatever right, you know absorb as much information so that way, you're not cold, start thinking. Okay, I need to do this anticipating what he's gon na ask you to do.

Keep yourself busy run to the truck grab different things. Someone left a really good comment and it made a lot of sense when you leave the walk-in freezer to run out to your truck. Keep your jacket on. Okay, even though you look like a silly weirdo in the middle of the summer, running out to your van with a beanie and a jacket on it's gon na help, because the more you take it off the more you put it on it's gon na start to Cause problems you're gon na get issues.

Okay, walking in and out you can, you can get heatstroke, you can all kinds of different things you can get. You know going from the hot and cold temperature can shock your body be cautious about that. Make the trips limited in and out of the freezer, but you know just have your your protective stuff, your PPE ready. Okay, have your beanie? Have your gloves and be cautious as you're walking around walk flat-footed? Don't don't walk on your toes or your heels, because you're gon na fall on your ass? If you do that, so alright, let's see what else I got just saw my message about knowledge sharing and liability.

Sorry, I'm late! Oh no! Alpha Alphonse! I actually have that on my list of things that I want to talk about, so I got some very interesting questions from someone. Oh yeah and the other thing. I wanted to point out too, when you, when you go out of the walk-in freezer, leave your safety glasses in the walk-in freezer or your glasses, whatever you're wearing, because if you leave with them on and then go back in they're gon na fog up. So just leave them in the freezer and then that way, when you come back in, you put your glasses back on, they won't fog up as bad okay.

They may still fog up if your body temperature is really hot but but walking out of the freezer. With your safety glasses on and go into your truck they're gon na instantly fog and you're gon na stand there trying to you, know clear them up so alright do I run a union shop? No, I live in Southern California, where we do not have a strong union. I work in Restaurant refrigeration, where the union is non-existent within the restaurant industry. I have no opinion either way union or non-union.

I will say: I've heard negative things about union companies and I've heard negative things about non-union companies so either way, whatever floats your boat, okay, but no, I do not run a union shop. I couldn't profitably run a union shop doing restaurant refrigeration in Southern California. It's just the prices are too high. Just couldn't afford it all right.

Let me go ahead and go to my list here. So how do I properly ordered or heaters and/or parts? Okay and I'm paraphrasing the question again for that matter, anything right to properly order parts and to know what parts to order you have to have experience. Okay, so I mentioned in the beginning of the stream. When I do door heaters, I change door hinges.

That's from experience okay, but if you don't have the experience, talk to other service technicians and listen to what they have to say, pay very close attention when you're disassembling things: okay, when you're taking a heater track cover off of a door heater, don't just yank the Damn thing off from the bottom: don't get the bottom loose and then just start pulling because you're gon na end up bending the heater track. You you got to think logically you're dealing with a very, very small, thin sheet of metal and if you pull from one end at you know it's gon na bend right. So you got to think about things and you got to try to predict the worst. As far as ordering the parts you just want to look at it and think like what, what am I gon na have to do to change this heater, you know when you go to diagnose a door heater, don't just look at it and say yeah.

It's bad measure the voltage lift up the threshold if you can look and see if there's ice all under there look and see if there's something that the heater sits in that it whines back and forth. Looked in my situation when I change the threshold, I pulled it up and I noticed that the grout was all messed up. I didn't see that because I didn't diagnose it, Oh actually, yeah. No, I didn't diagnose someone else diagnosed it.

So I didn't see that I was gon na have to take a threshold with me. So you know, we didn't know that and I ended up having to pick up a threshold on the fly and it extended my job by about an hour and a half, because we had to stop. We were doing have a stainless steel shop make a threshold. We took a lunch, I sent the guy that was working with me to go, get the threshold.

It took him about an hour to get back and I couldn't do anything really. I put the hinges on, but I couldn't do much until we got the threshold so anticipating the worst and trying to think what you're gon na need is very important when it comes to any parts in general understanding, sequence of operation. And what might go into that again going to change a door heater and thinking okay? Why did this heater fail? As I you know? Yes, it's bad! Yes, it has to be changed, but the entire time I'm taking it apart. I'm looking at it saying.

Why would this have failed? I'm trying to find a reason and then, in the bottom corner of my door heater there was one small burn mark on the the door gasket. So what that told me was very most likely. The electrical short happened right there and it did wasn't enough to trip the breaker, but it was enough to to to cause the heater to fail. So so just understanding sequence of operation.

You know trying to think of what you're gon na go through all right. I don't have any magic thing to tell you what parts to order for every single door heater other than when I change a door heater. I change hinges. That's you know, that's just my my thing that I do.

Okay, can I talk about liabilities on a job for those doing side, jobs? Scott asked me that question so. First off, I don't do side work. Okay. The reason why I don't do side work is is because I don't have insurance that covers me when I'm doing side work, I mean technically.

I do because I have my own business, but you get what I'm saying if I'm a normal service tech and I want to do side, work who's insuring you, okay, whose tools are you using if you choose to do side work? So be it that's on you, but remember something that my service company carries insurance liability insurance. I have auto insurance. I have workers comp. I have everything on my service text when you're doing side work, you don't have any of that and if you break something you're liable legally you're, not even allowed to do so.

Much side work unless you creatively bill and the bill happens to be under the legal amount to have to have a contractor's license. There's some there's some creative billing practices that you can do to get away with some side work, but and then guess what happens when you do that side job and that not not any fault of your own that motor that you installed on the condenser fails when It's only two months old who's, gon na warranty it, and when are you gon na? Do it? Are you gon na go out there and do it when you know during the day, when you're supposed to be at your normal job, it just starts to create a problem. So I'm not saying you can't do side work, but there is a lot of liabilities that are involved in that okay. The next thing is: are you using your service truck? Does your boss know you're using your service truck, and did you know that, according to the IRS, your company's actually supposed to report that you drive your service truck home every night so that way the IRS can tax you on that I mean there's so much that I think I went off on a tangent when that didn't even make sense.

That was a fun fact, but anyways that's a whole nother thing. My brain goes in weird places sometimes, but you know there's a lot of liabilities when it comes to side work. Okay, what happens if you know you're installing a furnace and something catches on fire? Who are they gon na? Come after you, your insurance gon na cover you? No, because your insurance doesn't know that you're a contractor doing side. Where I mean it's a problem.

So again, I'm not trying to discourage side work completely, but personally I don't do it. It's just a headache for me. So there's lots of liabilities involved in that you know anyways, that's my two cents on that! One! Sorry, if I was going negative on that one, but all right yeah, I really appreciate the thumbs up button guys. It really does help out the stream when you guys hit that thumbs up button.

Okay, maybe I'm gon na, but never seen this on Christmas livestream yeah. Sorry, if the video clarity is going in and out that's a bummer all right am I still going to put up tool review videos? Yes, I am fluke 196. Just haven't gotten to it, but yes, I will. I still have an HR recap, video that I started working on today too, so we're gon na begin that coming out too, so the HR recaps going to come.

First, I got some cool interviews with spore looms some new products and stuff, and then I've got some video footage. I'm trying to piece together. The best footage that I have is the first time I ever went to an event with like a legit camera. So I'm not that great at filming stuff, so I got to kind of piece it together creatively to make it look half as good.

So alright, alright, let me go ahead and see what else we got going on here: razzy texts. So what tips do I have for a residential service technician that's crossing over into commercial refrigeration? I actually got a question about this yesterday, but then I had someone in the comments asked me right before the stream to so I'm gon na heat it up and kind of converge. The two so residential service technician, the first bit of advice that I can give you if your residential service technician and you want to get involved - is fully understand the residential, the refrigeration cycle and how it works. Okay, just looking at pressures doesn't do anything for you pressures.

Do not. They will not continue you through your career, just understanding. What pressures are you need to understand? Temperatures pay attention to temperatures, I don't care if you're doing, residential or refrigeration the temperatures are gon na. Tell you everything, because guess what we have 50 different flavors of refrigerant and they all run different pressures, but the temperatures they stay, the same, meaning that the saturation temperature you're still gon na run a 55 degree coil you know or whatever it may be, on a Commercial refrigeration, walk-in cooler, you're still gon na run a 25 degree, evaporator coil right, because you're still trying to maintain a 35 degree box, so the saturation temperature.

If you just look at the saturation temperature, the pressures will follow and you won't get so focused and freaked out when you see that the pressures change from whatever refrigerant or whatever refrigerant. So that's the biggest tip of advice is understand. Temperatures. Okay, excuse me understanding.

Temperatures is really gon na get you going, okay, understanding the electrical process that happens. Okay, when we go into commercial refrigeration or commercial air conditioning either one okay, you may not be dealing with 24 volt control voltage anymore in commercial refrigeration. You might be dealing with 460 volt coil voltage or 208 volt coil voltage or even 115 volt coil voltage right. If you're dealing with a trained, Voyager and telepak unit, it might have 115 volt contactors, it's still the same concept right.

You still check voltage the same. It's just a higher voltage, so it's really not that scary. If you understand the basics of how to troubleshoot things, it's gon na cross over when you get into commercial, whether it be air conditioning or refrigeration, yeah, there's gon na be some different controls. There's gon na be some different control strategies different things like that, but if you understand the basic concepts, if you understand electrical flow right, it's gon na still make sense.

It's really not that huge of a difference you're just dealing with bigger equipment, you've got bigger wrenches. Basically, okay, so I've never done residential air conditioning myself. As far as the business goes, I mean I've done it for family and stuff like that. But you know it's: it's still the same basic refrigeration practices just amplified, okay, so just understanding that kevie.

Thank you very much for that super chat man. I really appreciate that or that super sticker, I guess, is technically the payer dancing. So thanks a lot. I really appreciate that christian has asked if anyone here has seen any refrigeration equipment, including AEC units explode on the job.

I've never swelled, no I've seen stuff catch on fire, not even with flammable refrigerants, and that's something to think about too with just you know our 404 a or 134 a the oil can still ignite. So when you have a burnout, I've seen a flame come out of a compressor. I've seen a wall, that's torched from a burnout where you know the terminal vented and the oil ignited, and there was a brief. You know a little flame coming out, seen it.

So what happens on anything, but I've never seen equipment explode. No, and I wouldn't worry about equipment exploding so long as you're following proper refrigeration practices. I know there's some crazy videos that popped up on social media last year, like third world countries where things exploded and people got killed and different things. Like that mind, you guys a lot of that had to do with improper refrigeration practices, not pulling a proper vacuum.

People purging the system with oxygen like silly stuff like that, so be careful. Just follow proper practices. How was meeting all the famous social media texts? Ernesto asks me: HVAC are vloggers, so that was very cool, getting to go to the HR, show and meeting all these other content creators. That was really neat I got to, and I said this on the last one guys, but the highlight of the HR show right.

There was so many cool things right getting to have dinner with Gil and Scott HVAC rookie, getting to sit down, had a dinner table with Andrew Greaves, dick, worse, Brian or and Jim Bergman, all at the same end of the table having a beer or there drinking. Whatever drinks, they're drinking and eating dinner, that was really cool to get sit down and have conversation with those guys. That was a really really neat. That was probably one of the highlights of that event, but there was so many other ones getting to sit down with the the the founder of field piece and have dinner, or have a lunch with him, where we were playing top golf.

That was really cool. You know getting to meet all the spoiling crew, all the really awesome people from sport'ln and actually again silly fun fact right, sitting down going to dinner with the people from spoilin, in my contacts there and then talking with them at dinner and realizing that a lot Of them live and or have family in the place where I was born, which is Rolla Missouri that was really cool to sit down and talk to them, like oh yeah and just mention to them yeah. I was born in Missouri and they were like where and then you know just guys it was such a great experience again. I'm hoping that the recap video that I make kind of shows you know what, how cool it was.

It's probably not gon na translate completely, but it was a very humbling experience to get to sit down and meet all the other HVAC youtubers instagramers, all those different things. It was really cool. So, alright, let me see what else you would think our 290 can explode. Kristian Frederick's, yes, it can.

But what let's break this down? What do you need for an explosion to happen? Okay, what do you need for fire? What do you need for combustion? You need oxygen, you need fuel and you need a spark.
