Hey guys how's everybody doing I'm just gon na kind of let everybody file in here for a minute, so we're gon na let the user play for a second. You guys hear me, okay in the chat right on I'm just gon na. Let a few more people file in before we start up, hey guys. Alright, let's go ahead and get this thing started.

So I know I'm a little bit early. I usually come in Monday evenings, but we got holiday plans today. So I just kind of wanted to get this make sure I got one in because I skipped it last week, so hopefully everybody's having a nice holiday, Merry Christmas to you, guys, Happy Holidays, Kwanzaa, Chanukah, all that good stuff. So today's topic just kind of wanted to answer some questions.

We had a lot of questions from the last couple videos because of course, I missed the last livestream, so had a bunch of questions from the last couple videos and wanted to kind of answer. Some of those and then kind of thanks a lot Adam woods appreciate it. Man merry Christmas to you too, just kind of wanted to address some topics too. Okay, you know in my last couple videos and actually pretty much in all of my videos.

I hope you guys know that you know, and I try to stress it in most of my videos when I, when I'm videoing too, is that I don't know everything. Okay, I'm just a technician. Just like you guys. I've made a lot of mistakes.

I've learned from a lot of my mistakes, but I'm still learning every day. There's new stuff, you know new new things, there's things that I realized that I do wrong. That's taken me a while to realize that you know, and it also there's there's multiple ways to do things too. So everybody kind of has an opinion, and you know everybody has their own way of handling things.

So the one thing that I kind of wanted to address and it's been brought up a bunch lately - is electrical terminologies and electrical mistakes. Okay, I I do admit you know in some of my videos. It does come up to me. Get brought up to me that I've made mistakes, you know electrically, you have to understand something.

A lot of my videos are added down, so you know I can't sit there and film the entire thing, because I have to work too. So you know a lot of times. I cut certain things out and I realized I probably shouldn't cut you know. For instance, it was brought up to my attention that I dove into an electrical circuit without verifying that the power was off when in fact I did verify it's just that I didn't get it on video okay, so you know I get it especially.

You know, because I realized that there's a lot of new people to the trade that watch these videos and I do want to make sure I'm setting a good example. But I can promise you guys that I am being extremely safe when I do stuff and a lot of times, if you think that I missed something a lot of times, it's just not in the video. Sometimes I will even you know, diagnose something a little bit before I even turn the camera on. Okay, so just know that you know I am being safe.

Merry Christmas to everybody, that's coming in! I see you guys filing in the chat here right now. We're just kind of getting started just talking about some some things that were brought up in the chats in my last couple. Videos so kind of - let you guys keep filing in here - hey guys, how's everybody doing for those of you. I don't know if there's anybody new in here right now, that's watching just kind of give you a little context as to what's going on.

So my channel name is HVAC our videos. Obviously I upload videos Mondays and Fridays okay, usually early in the morning, and then I usually do a live stream on Monday evening to answer all the questions from the previous couple: videos. Okay, so last week I missed the live stream due to holiday stuff, and then today I'm actually doing my live stream early. Usually my live stream start at 5:00 p.m.

Monday Pacific time, but I'm rolling it in early because we've got a big family Christmas thing today. So we started out a little bit just talking about some Electrical mistakes that I'd made in the last couple videos - and I was just explaining to everybody that you know some of those mistakes are true mistakes, but then some of them are things that you guys. Just don't see because I don't film necessarily everything when I'm when I'm you know, shooting my videos, okay, so terminologies! You know, I do make electrical terminology mistakes all the time, my biggest one that I gets pointed out to me and I realize I make it all. The time is on a 208 volt circuit, when I rely refer to the common terminal as the neutral.

I constantly do that and that's just something I cannot get that on my head for some reason. I constantly do that and I think it comes from working on walk-in freezers with defrost clocks and the common terminal is usually the end terminal. So that really throws me off and I constantly call it the neutral terminal when in fact it's not actually a neutral. So you know also understand that all of us guys that make videos on YouTube.

You know we don't know everything. Okay, it's it's to your guyses benefit to to fact check what you see to read up to to you know, investigate things, don't always assume just because you see some guy that has a lot of subscribers. That he's always right. Okay, cuz! I am NOT always right.

I guarantee you that I make mistakes all the time every day to this day, the important thing is is if you can learn from your mistakes, and I try so all right. So you know just just just want to point that out. You know that we are always learning and it's important to that. You stay humble because it'll kick you in the ass.

If you don't you'll get your ass handed to you by someone. You know I've made mistakes before where I've gotten cocky or something like that and said you know no, I know I'm right and then turns out. I was wrong. I've had apprentice technicians, it's not an apprentice.

I had a new guy that he works with me right now and I made a big mistake and - and he was trying to be polite and telling me that I made the mistake - and I was like no, I didn't know I didn't, and then I realized that I did you know so it happens all right, hey guys, how's everybody doing see more and more. You were filing in right now, oh right on yeah, it's interesting because this isn't my normal time to do this live stream for the guys that are just coming in. I usually do them at 5:00 p.m. Pacific time and I'm just kind of getting this one done early because of holiday stuff.

So a couple other things I want to cover in my videos: there's been a kind of a common thing going on right now for those of you that work in restaurants and deal with we're at Restaurant refrigeration. I am NOT it's funny. I find it comical, but I am NOT gon na acknowledge the locations. I know everybody's always trying to guess where I'm working at, even if you guess right, I'm not gon na - acknowledge that it's right, okay, guys, I have to protect my customers and I have to protect myself.

So I'm not gon na divulge. You know the names of the locations that I'm working in in my videos. Okay, not that I'm doing anything wrong. I am always 100 % on the up and up with my customers, and I make sure that if it, if I feel like something, took me too long, because I spent extra time filming or something like that, I will never build my customers for that.

My customers are too important to me to to screw that up and the relationships that I've built with them are very, very important. So you know, but just keep that in mind. I know you guys are, you know not trying to be rude or anything, but people are just asked. You know is this this, or is this that and I'm not gon na, tell you guys where the locations are and for those of you that do know, because it's you know some of you that work in these places can obviously tell where I'm working at I'd Appreciate it, if you guys kind of just keep that to yourselves most of the time, if I see them in the comments, I actually delete the comments and it's not I'm not upset.

I just prefer that you know the restaurants don't be in my you know comments. I just don't want people knowing and stuff and Merry Christmas everybody appreciate it just kind of looking through the chat here right now: okay, upper level HVAC, I'm gon na answer a question real quick. You asked what was the start of my HVAC Korea likes cooling. First job, okay, so for those of you that don't know I started in this trade when I was a little kid, I actually work for my well actually I work with my dad now, but I started working for my dad as a little kid whenever I was Off school, you know whenever I was on vacation or anything like that, and especially in the summers that would work with them.

I used of my mom and my dad lived in. You know they were divorced and lived separately, so my dad would pick me up oftentimes right after school and then I would go. Do service calls with him on the way home. You know that kind of stuff, and so I kind of grew up in the trade.

It's funny, though, because I didn't want anything to do with the trade I hated it. I hated the heat I hated. The just seemed like it was a pain in the butt to have to climb onto the roof all the time, but Here I am now - and I love it so I officially started in. Thank you very much.

Rehab junkie, I officially started in 2002, was when it was official that I actually came to work for my dad at the time, and it's just been a long ride ever since we have since partnered up and now I'm part owner in the company he's part owner. He's not really involved in the service work anymore. I did go to trade school. I went to the local Community College Mount San Antonio Community College here in Walnut California, it's about 45 minutes from my house took their HVAC program and then, at the same time I was still learning and I just kind of got a good mix of it.

I spread out the HVAC program over a couple of years. Just went to night school took, you know two three classes at a time that way I could work at the same time and he you know it's been. It's been a lot of years. So lots of mistakes made learn from a lot of mistakes.

So alright, let me see him just missing up in here. Hopefully I answered that question okay, for you guys so, just to reiterate: I'm not gon na divulge the restaurant locations that I'm working at like I said I had a really good question in my chat a little while ago about the recent ice machine, video that I Did - and forgive me I don't have your name written down, but you it was a good question in there and they asked me: do I always use a certain size liquid line, filter dryer. Do i upsize the filter dryer. Do I use the factory dryer? I always try to go back with the factory dryer if at all possible, there is times where I need to make a field, and I don't have the factory dryer on me at the same.

You know at the right time, but if I end up having to order factory parts like expansion, valves and whatnot, I will try to put the factory parts back in and order them with it. But I do carry aftermarket filter dryers on my truck one of the more important things that you want to understand, especially when you're working on ice machines is, they are critically charged, and that means that they only have - or they have to have a specific amount of Refrigerant in them to work correctly critically charged systems, especially when they're smaller charges. You know, sometimes you get to a nice machine that may only hold you know less than a pound of refrigerant. It's very critical that you put the exact components back in that system and that you don't change anything.

So if I went with a bigger filter, dryer on a critically charged ice machine, potentially the system could be under charged because we have more volume in that dryer. For the refrigerant to sit, there's all kinds of things, so that's why you try to go back with the components that belong inside there. Okay, there is some logic you can do in your head to just because it's a factory liquid dryer. It may still be a 32 cubic inch dryer.

Okay, most liquid line filter dryers are rated in cubic inches, so you may be able to look at the dryer and say: okay, that's a 32 inch cubic inch dryer, some Hoshizaki x' will come with that and if I can't get the factory dryer, I can make Sure that I put in a 32 cubic inch aftermarket dryer in the system. Okay, now on some of the bigger machines, I'm not so worried about it, some of the machines that might hold 910 pounds of gas - I'm not gon na, be too much worried about going. A couple cubic inches over the dryer size. So if we get on a bigger Hoshizaki ice machine, you know I might put a 16 3 or an O 83, something like that.

Okay, so you know it's just important to understand what you're working on try to go back in with the factory parts and that's kind of the way that I go with everything. I try to go back into the machines with the factory parts as much as possible. So for those of you guys that are just coming in I'm just kind of answering some questions from the last couple: videos, okay and just kind of going over a few things, hello to everybody. Thank you guys very much.

Merry Christmas Happy Holidays to everybody. Okay for those of you that are new thanks for coming in guys, I really appreciate it and I'm gon na keep going alright well guys. Thank you so very much. It's not expected that you guys do these super chats and different things, but I really appreciate it.

Okay, Ryan Leary, yes, through his wiggle room uncharged, especially when you get into the bigger ones, okay, but when you get, I honestly don't work on a lot of small ice machines. Ryan. That was you wasn't it that showed me. The you there was a picture of a tiny little under counter Hoshizaki ice machine on a residential system.

Wasn't that you that posted that on social media? That would be an instance where I would make sure I would go back in with the exact factory parts. Okay, if you get into these very, very small under counter ice machines, especially the residential series, yeah yeah, so especially the residential lines on something like that, you need to make sure you go back in with the correct size or you need to become a field engineer And adjust the refrigerant charge on the spot. Okay, I don't suggest people doing that, but try to stick with what belongs in those things. Unless you really really know what you're doing.

Okay so always be cautious about that. Oh right on! Thank you very much Daniel. I really appreciated that man, okay, so another okay, so this is actually a really good point, I'm just kind of going through it. I got like a little list of questions right here, guys that people have sent me and I thought were more important, replacing parts due to ease and what I mean by that, for instance, on my recent video, where I had bad expansion valve someone brought to my Attention that when they work on Hoshizaki ice machines and they have to remove the charge that a lot of times they'll go in and change the hot gas valve okay, I agree with that and I don't agree with that and I'm gon na tell you why.

I too will do the same thing in certain instances and when I say I don't agree with that, I mean that you have to evaluate the situation you're in so, for example, I had a Hoshizaki ice machine that had bad expansion valves and someone brought up in My comments that they typically will change the hot gas valve also at the same time, and the reason why he does. That is not necessarily a sales thing. But if you work on the Hoshizaki ice machines, a lot one of the parts that fails quite often is a hot gas valve they'll get stuck open now, in my opinion, the reason why they get stuck open is typically because people do not follow the proper refrigeration Practices when they were installing components in the system, okay - and it is if, if you know that the system hasn't been worked on correctly, if you know that you've had problems with contamination in it, then I would agree with that. Okay, but I would say that if we follow the proper refrigeration practices, we shouldn't have to worry about situations like that, because the hot gas valves typically don't go bad unless something gets stuck in them and the only way for something to get stuck in them is, If someone didn't follow, you know proper practices when they were brazen in a dryer if they weren't, you know if they were going crazy if they weren't purging nitrogen.

Now I will also say purging nitrogen on an ice machine is extremely difficult. Okay and I'm gon na be honest with you. I don't do it most of the time, because there's so many valves in those ice machines and there's so many little crevices and places that it's not just a single pass like you're working on a simple residential air conditioning system where there's nothing in line. Okay.

On an ice machine, you've got all kinds of valves: you've got hot gas jobs, you've got Headmaster's up on the roof, you've got liquid lines, solenoid belts, you've got a bunch of different valves and it's not necessarily easy to get all of those open and the nitrogen Won't necessarily sweep through the entire system in a nice even flow. Okay, I'm not saying that it's a horrible thing to use nitrogen, I'm just saying it's kind of difficult when you get into these complex ice machines to purge with nitrogen. So I'm admitting right now that I'm not always gon na purge with ice with nitrogen when I'm working on an ice machine - okay because it just creates havoc for me, that's my personal preference, I'm not the the end-all be-all! You know answer for that. Okay, I I'm not perfect.

I do make mistakes, but that's just my personal preference, okay, so there's a lot that goes to or a lot that goes into brazing and if you know how to braise properly, you know if you're, not overheating systems, you can. You can get away with some things again. I want to be cautious about that guys because I don't want to teach you guys the incorrect two things I'm just saying, there's a time and place for following certain practices and there's a time that doesn't work. Okay, on the same instance again, I always think that you should, you know, use proper vacuuming practices that you should use all the fancy, hoses and micron gauges and all this different stuff, but there's also a place and a time for that.

Sometimes, when you're working on small self-contained regions, you're not gon na, be able to get all that fancy stuff on there and guess what? Sometimes it's not practical to put vacuum core removal tools on a small self-contained reach and sometimes there's no room in there. And sometimes you just have to vacuum down through your manifold. I know that's sacrilege, everybody's gon na crucify me for that. But sometimes you know you just got to do what you got to do.

I always always want to try to use vacuum core removal tools. A pion mega flow hoses or true-blue, hoses or whatever, whenever I can but there's just some times that it's not practical. Okay, so just understand, that's my opinion, so that's the total tech. You didn't.

He brought up a good point. He says first learn the trade then learn the tricks. That's true, okay, it's always important to understand why we're vacuuming down a system the way that we should be doing it using vacuum, cord removal tools - and you know, hoses without a manifold and different things, but again sometimes it's just not practical so to each their own. Not crucifying anybody, I'm not.

You, know the the greatest tech in the world, so all right so, okay, another really good point that was brought up to me is people talking about repairing parts. Okay, personally, I don't rip and when I say repairing parts, for instance, one of my videos where I as I think it's called walk in the walk-in freezer Electric defrost explained or something like that. I think that was the title of my video and I had a couple people and they're saying: why didn't I pull out the circuit board and repair the relay on the defrost clock? Okay, I understand what people are asking me about that and what they're saying is is to take this. The printed circuit board unsolder the little black relay from the printed circuit board and then replace the relay.

If you do that great, you know that's cool for you! For my business that doesn't work, and I'm gon na explain to you why my customers expect me to warranty the parts that I install and I have told my customers that I will honor factory manufacturers warranties. So if I buy a defrost clock and they warranty it for one year after purchase, then I'm gon na warranty that part for one year after purchase, and I will typically give him about 90 days, labor on it. In order for me to stand behind that part and honor the manufacturer's warranty, I can't repair the part and when I say I can't unsolder a relay off of a defrost clock, excuse me and try to repair it. It's just not practical for me Plus.

At the same time, I've got people that work for me and I can't pay them to try and repair something like a relay on a defrost clock and then have it fail, because then I still have to pay my technician. I still have to pay for the part, and then I have to warranty something too, so it just doesn't work that way. It's just not practical for me to do that when it comes to like defrost clocks and printed circuit boards. So if, if a defrost clock goes bad, I'm changing the entire clock, okay I'll even go as far as saying on a grassland defrost clock, I won't change just the module, even though sometimes you can like, if you have a defrost module on a grassland clock, that's Kind of stuck and it's moving kind of slow.

You know I won't change just the module most of the time. Okay, because the customer doesn't understand that I change just the module so the next week, when one of the relays fails on that defrost clock and I change just the module, then you know they're still gon na want me to warrant yet they're gon na say. Well, you just change the clock, no, I did and I just changed the module on it and then now the the main clocks, bad that doesn't you know they don't understand that. So it's not practical for me to do that kind of stuff.

You know I got to think smart as a business person too, and also look out for the customers best interest. So in my eyes, if I've got a defrost clock that has a bad module on it, and this is just my opinion - I'm not not knocking you for doing that. If you do okay, but for me it's not practical to do that kind of stuff and it'll end up costing the customer more in the long run. In my opinion, if I try to repair one of those parts versus just replacing the entire clock, the clocks are cheap.

It's not a big deal, you know. So you know I get a new clock for 70 60 bucks or something like that. It's no big deal, so I'm not in the business to repair printed circuit boards and on smaller horsepower motors, I'm not in the business to try to pull the motor apart and change bearings. I can understand on a 50 horsepower motor, you know pulling it apart and servicing it.

I get that okay, but on these small little things it's not it's not practical when, when the part only costs, you know 200 bucks or something like that, it's not worth the labor involved to try to pull it apart and change bearings on the motor or something Like that, so, in my opinion, okay, so I'm going to I'm going to kind of scroll back here through the comments and see what I missed here guys and try to get to some of your questions here. Thanks a lot guys Merry Christmas, I really appreciate it. I see all these comments coming in guys and for those of you that soup did super chats. Thank you so very much.

Okay guys. I really appreciate that. Okay, so let me go back up in here and see what I missed biggest advice. Jakub Harriet asked the biggest advice for an apprentice in the trade.

My best advice to you Jacob is be a sponge. Okay, don't get cocky, don't get rude, listen to everything and absorb everything. Even the bad advice. Listen to it! Just keep your mouth shut.

Let the people tell you you're your Foreman, whoever it is. Let them tell you what's going on, let them explain to you their methods, just because you know it's wrong. There could still be some value in what they're teaching you. So let's say, for instance, that you know you're the person you're working with your mentor, whoever you're looking up to, and he says you know we're gon na change when we change that compressor.

We're gon na change the expansion valve okay and then you ask well but the expansion valves not bad and he's busy he's working, and this is something that's been asked to me. You know, and sometimes I don't have the time to explain it at the moment and I may say: look we're changing the expansion valve, we'll talk about it later. He has a reason whether or not you think it's right or wrong finish out the job and then ask him after like okay. Why did we change the expansion valve when we changed that compressor and he said well because it was a burnout and more than likely when that compressor grounded out it contaminated the system and either the expansion valve got contaminated and or the expansion valve was bad.

To begin with, and it caused the compressor to go bad, so what I'm saying is is just just listen to what he has to say chill out relax, even if you think it's wrong just you know just listen and talk to him and there's you know. While people are on a job when you're working they're, not necessarily gon na, be able to explain every single thing to you, okay, so it is gon na be partially your responsibility at the end of the day to to try to remember what he says and then Go home and research, the hell out of those things, go on the internet. Go to the HVAC talk form. You know, research, some things, that's what I used to do when, when I didn't know the answers to some things.

Okay, so be a sponge. That's some really important advice that I could give you research. Okay, wait just because you clocked out at the end of the day doesn't mean your day is over. To be honest with you, your day probably needs to go on for a couple more hours when you clocked out and you get in your vehicle and you drive home or you you know you get to your house, then you you, you probably need to sit down And do some research pull out your computer and spend an hour or two each night researching some things that you were curious about as the day went on? Okay, the more you learn that the better you'll be especially when you're an apprentice to take the time to get educated properly.

Now, even if it involves going to a nighttime community college or something like that signing up for supply house courses that they offer trainings and different things, a lot of manufacturers. Now it's a little bit different than when I was coming up in the trade, because the internet really didn't exist too much. When I was coming up, it wasn't as accessible and easy there's so much information available on the internet. If you're working on a nice machine, pretty much every ice machine manufacturer publishes all their training classes on their website.

So I'm not saying you shouldn't go to a training class in person, but majority of the time what they're gon na teach you in that training class is available online. So as an apprentice, I think it's your responsibility to go home at the end of the day and research, the hell out the previous day. You know I mean just research. Everything act like a sponge when you're working on a job, take pictures of models and serial numbers take pictures of things that you think are awkward or strange and then go home and analyze them look up models and serial numbers print out the manuals you can get It all online, so I think today is a great time to be an apprentice, because there's so much information available to you.

So I think it's a great time as long as you're willing to put in the effort. Okay, I'm gon na go through to the next comment here. Cbcb you asked: if it's possible, I could do electrical troubleshooting videos teach you the process of elimination yeah. I definitely can try to do that.

I will. I will put that on my list of things to try to remember now. One thing: I'm gon na explain to you guys if you guys haven't already noticed: okay, there's a lot of information missing from my videos and there's there's a reason for that. I do not want my videos to be a resource for DIY people, restaurant owners and homeowners to try to fix their own equipment.

That's not what my video or four okay, but at the same time, it's not just because I don't want them to work on their own stuff. It's because I don't want people to hurt themselves. Okay, my videos are are tailored towards people that are already in the trade and that have gone through proper schooling and know the basics of electricity and electrical fundamentals. Okay, so you notice, I'm not going to tell you exactly eight.

You know in my videos, you'll notice that you may see step one step two and it's missing: half the middle and then you'll see the ending result. Okay, because I I don't want them to be a DIY resource for people to potentially hurt themselves. Okay, I try to show you guys what I think as technicians. You guys will understand, and you know that's where I try to go with my videos so and it's also a liability thing too.

You know I don't want someone to get hurt. You know, I don't want to explain to you how to use an oxy-acetylene torch. This is how you set your regulators. This is how you light your torch.

This is what, because I legally don't have the insurance that protects me as a person to show you guys. All that information, because, God forbid, you didn't hear something correctly and you set something wrong and something caught on fire. I don't want the liability of that coming back on me. So that's another reason.

It's just one of those things that kind of sucks, but it is what it is okay, so I do have to limit some of the things that I shown in my video, but I will definitely work on a video where I can teach you process of elimination And how to troubleshoot an electrical circuit that ones one that I can safely do okay, so I will work on that. Alright gon na keep going down here, seeing what I'm missing guys. What are my thoughts on drop-in replacements on refrigerant out there? Okay, I am probably not the best person to ask that, and that was asked by Mike 29:59 and the reason. Why is because I honestly don't agree or use many of the drop in refrigerant replacements.

Personal preference do not use my word as everything. Okay, they work for some people working with my customers. My customers are okay with me using r22 refrigerant still be they don't want to have to go through all the headaches and the problems of converting a system over to one of these drop-in refrigerants. So at this point in time now I'm not saying I'll, never use them in the future, but right now, I'm just using r22 4:10, a 404 1:34 and that's pretty much it in our 290.

Those are the only refrigerants I'm using at this point in time and a lot of times. That's my customers that are requesting that I would deal with a lot of national chain. Restaurants and I've brought up to their facilities departments. Hey.

Do you want to try to save a couple bucks and start using these drop-in refrigerants and most of the time they've all said? No, they just rather me stick with the regular ones, because they'll go ahead and replace the equipment versus doing any giant major repairs. Although there's some of them that I've made videos on where they probably should have replaced equipment and they didn't - but so I'm not the greatest person to talk about the drop-in retrofit refrigerants, they work for some people. They just there's a lot of disclaimers in the the instructions that I don't appreciate and don't agree with. So that's why I tend not to use many of the drop-in refrigerants, but I'm not saying I'll.

Never do it if a customer told me that they wanted me to use a drop-in, then I would do it and I've used them a few times in the past with not great results. The drop in refrigerant that I used in the past was our four 27a, and it's not that the refrigerant didn't work. It's just that I didn't know all the details and all the information wasn't in front of me. I've said this before in a past video that I used our four 27a on a train voyager package unit with a 3d with a ten-ton 3d scroll in it, and we lost the compressor like two days later or a day later, or something like that, because the Refrigerant wasn't making it back to the compare the oil wasn't, making it back to the compressor.

Let me step back by saying that compressor had mineral oil in it and on the our 427, a instructions that said it worked: ok with mineral oil systems that you did not have to change the oil. Well, what I learned after the fact on that particular system is, is that it doesn't work very well with mineral oil and the Trane compressors require that oil to come back with the refrigerant to lubricate. The I think it's the upper bearing on those 3d scroll compressors and that thing didn't get its lubrication and within a day, basically that compressor seized and it was a brand-new compressor and it was just a nightmare. So anyways I digress on that one but yeah.

I just I'm not a fan of the drop in refrigerants at this point in time. So, okay, keep going down here and also to Train Manufacturing is very interesting, so they have some published documentation. That says. If the unit is under warranty, they will not approve any alternative refrigerants, but if the unit is out of warranty, they have some refrigerants that they will sell you so come on.

Do the math there so basically train supply houses wants to sell you. The drop in refrigerants, but if it's under warranty they won't warranty the the equipment, if you use it. So what does that tell you that tells you that the manufacturers are not behind those drop in refrigerants as of yet so that's just another thing. If I, if I had a manufacturer that said they would warranty it, if I used it, then you know I might be more okay with it, but if I have to eat the money like I did on that 10 ton compressor, I'm not gon na, be a Happy camper, so, okay, I'm sorry! I cannot pronounce your name.

It says: what's the best place to acquire an education for HVAC, is there a specific school also? Is it better to go to school first, or should you get some experience? First, as a helper, I honestly don't know where you are, whether or not you're in the United States or not. I would suggest that you check out your local community colleges or trade schools. The thing I like about the community colleges is that you can go do night school, you can take one or two classes without paying for everything up front. You can see if it looks interesting to you and on top of that you can try to get an apprentice job.

You know or an apprenticeship with a company where, as a helper while you're going to school at nighttime, in my opinion, that's the way to go. Not knock in any of the trade schools, but I'm just saying the Community College is cool because you can work during the day and you can go to school at night. I'm gon na be honest with you as an employer. If someone comes to me and says, hey, I want to get into the trade, but I have no experience it's harder for me to hire them versus.

If they come to me and say: hey, I'm really interested in the trade I've already enrolled in Community College. I've been going for to some I've got these classes behind me and I'm really interested in in starting out to make sure this is what I want to do and working as an apprentice or a helper. I would be more than willing to hire that person because they showed me drive. They showed me that they're interested in the trade, and not only are they interested - they actually have been applying themselves by going to school, and now they want to come in as a helper and learn on the job, I'm totally willing to teach someone.

That's my methods and that's the way I like to do it so I'm not knocking the trade schools. You know a lot of times the trade schools. You can get subsidized education different things. You know there's all kinds of different ways that you can do it, but I'm just a fan of the community colleges, because you can go to school at night and still work during the day.

Ok, um keep going down here. I'm just kind of getting to these comments. Guys, ok, keep going! I'm just looking through here, seeing what I'm missing guys hello to everybody. Merry Christmas to those you guys that are just coming in! I really appreciate you guys taking the time.

Ok, po Duc 10. You asked why, on Christmas I make a job video that I make my videos guys usually in advance. So, for instance, I've got three videos sitting scheduled for the next three uploads. So that's why I uploaded today and I'm doing this and also because I missed the last livestream last week.

So I wanted to get on here and and do this ok keep going down here and see what I missed yeah. I really really appreciate it guys if you hit the thumbs up button on the video it does help me. Ok, let's go down here. Merry Christmas Rick appreciate it ha Adam Mew Fitch.

How do I find new help good help? You keep getting burns yeah. I keep getting burned too guys not to go off on a rant, but unfortunately, right now in the trade we have a we're having a hard time as if you guys, probably already don't already know, we are having a massive shortage of skilled workers. We've got an influx of new blood coming into the which is good, but we've got a larger outgoing group of experienced trades people leaving. So you know it's difficult right now to find people that want to work hard.

The trades are not for everybody, but I will say that they are very, very rewarding if you work for the right company and you work for the right person and you do what you like. There's no sense, I'm working for a place where it's just a nine-to-five job. This is my opinion. Guys.

Okay, in my opinion, is, is that you know you shouldn't be doing this. If it's just a job to you now, I'm not saying that you need to treat it like. It's your own everything and you need to worship this job and everything, but I'm just saying if you're not interested in it. There's no point so, but I think a lot of people think that it's gon na be an easy job and they jump right into it.

And it's not easy when, when you really have to go home with headaches, sometimes thinking about things and and worrying about things - and you know so it's definitely an interesting time right now so Freddie you ask if anyone works in supermarket refrigeration, I don't work in supermarket Refrigeration, there may be a few guys in in this chat. I I don't know how many of them will be doing supermarket, because my chats are usually more restaurant and HVAC stuff. There's some people that you can reach out to on Facebook, see if anybody chimes in in here but prime time does it looks like yeah but um. You know reach out to some of the Facebook groups that you can join, that you can talk with other like-minded people in the supermarket groups and different things like that.

So Adam right on okay, keep going down here and seeing what I'm missing Adam wood says: the trade can ruin your life, but it can be rewarding. Yes, the trade can ruin your life and yes, it can be rewarding. You know it just depends on on what you want to do. Okay, it can wear you out.

Definitely I've made a few videos on that. The summer times can be pretty brutal. You know, but at the same time, if you learn to just take it as it is, and try not to work too hard, and you know it could be very rewarding. Excuse me all of a sudden.

My nose starts itching like crazy. Merry Christmas Ulysses, thanks for coming in the chat, but okay how's everybody doing Ted how you doing today, man yeah, that's right, Ted, more hours and less pay come on over okay. Let me see what else I'm missing here in this thing: okay, all right! So there is a lot of different people on YouTube. There's a lot of people that probably don't make the greatest videos.

There's people that make great videos. You know again. You can learn something from everybody, even the people that don't make great videos you can learn. What not to do.

You can learn what to do. I make lots of mistakes in mind, so you know call me whatever you want to call me. All I can say is has learned from my stuff learn from what I try to tell you guys. I try to give you tips and advice on on problems that I have had and on mistakes that I have made.

I know that's a difficult thing, because a lot of people don't want to they want. I don't know, a lot of people seem to have hesitation and they want to make mistakes, and you know don't want to listen to other people. But if you can listen to what all these other guys are saying, you know what I'm saying what other people are saying. Then you might be able to not make some of these mistakes and it might make your life go a little bit easier.

So, okay, primetime! Yes, okay, so primetime is asking about a video that I did on a late night. Walk in freezer service call where I went out there and I had a evaporator coil that shorted out the the heater shorted against the solenoid valve wire. So let me step back. I had a service call.

I went out there found that the system was not running the evaporator coil was not running and that a I was not getting the correct voltage at the thermostat. So then I investigated, and what I found was that the solenoid valve wire, coming from the temperature controller, had shorted out against the defrost heater, the wire wrapped, underneath the defrost heater and shorted out, and it just broke the wire clean off. For whatever reason it didn't trip the breaker okay, at least I don't think it tripped the breaker anyways, so I repaired that wire started the system back up and when I started it back up, I came downstairs and all the sudden refrigerant was spilling out all over The walk-in freezer box, okay, ran upstairs real, quick pump. The system down.

I had not put my service gauges on it yet because I thought it was just gon na be an electrical issue ran downstairs real quick. I ran upstairs pump the system down shut. It off came downstairs found out that at the same time, a wire, I'm sorry, a heater hanger, which is like a little metal hanger that hangs on the evaporator coil had shorted out against the defrost heater when that short happened, and it blew a hole in my Evaporator coil too, but when it blew the hole in the evaporator coil, the solenoid valve had shut off. If that makes sense to you guys, so it only leaked out the refrigerant that was in the liquid line.

So when I repaired the the electrical short and turned the system back on all of a sudden that still annoyed valve opened back up and it started leaking refrigerant again go watch the video it's an interesting one. Yes, I did end up changing that coil and I've. Actually already had problems with that replacement. Coil too, I can't remember if I've made a video on it or not.

I don't know - maybe I haven't, I haven't released it yet, but yeah I've actually had republic oil to where it's been iced up, because the customer keeps icing it up. But yes, I did replace that evaporator coil! So alright I'll keep going in here real quick, seeing what I'm missing! Okay, yeah guys didn't see the total tech. I think you're talking about it where Brian or made a contest where he was making a asking everybody to make a polite meme about Jim Bergman. Some of those were pretty funny, yeah guys I didn't have to work today.

Actually, we we, as a company, took Christmas Eve off so the on-call tech is on call, but he knock on. Wood hasn't had to do any calls yet today, so we Christmas is a paid day and then Christmas Eve we usually just take the day off. It's not a paid holiday for us, but it's nice just to get the day off so all right. So anybody else.

Okay, let me read this Randy laughs. What do you like better Chris HVAC, refrigeration Randy? I, like I like them, both to be honest with you, but I like refrigeration refrigeration is is, in my opinion, it's a little more. I like the troubleshooting that goes in with the refrigeration. I mean not saying that HVAC doesn't have interesting troubleshooting to, but it does, but I like troubleshooting walking, coolers and walk-in freezers.

I you know what I really really like. My one of my favorite parts of this trade is, is bending pipe actually doing installs getting to pipe in walk-in, coolers and freezers. I really like it when I get to do complex piping jobs and I get to work with with the tubing benders and do all kinds of complex bends. I enjoy that.

I I'm very I'm very anal when it comes to things and OCD and different things, and I like to be able to to use my skills and I like to be able to see a finished job after I've done a bunch of bends and it look all Clean and awesome, you know and not look shitty, I'm very particular about the way that I like to do installs and different things. So I like doing installs, but then I love troubleshooting refrigeration. So all right keep going through here right on Guido Shadid man. Looking at the big picture, that's my motto, man, you know always always look at the big picture solve the problem, not the symptom, I'm always saying that and I think that's really important guys.

So all right guys. Any other questions you want me to answer. If not we're gon na probably end this one pretty pretty early today, let everybody get back to their normal days. Jannard yeah, I was kind of afraid to say I like bending pipe, but I don't know if someone's gon na crucify me for that.

But now I love doing that Paul. What do I feel about side jobs? Personally, I don't do side jobs very much as a business owner. I'm not a fan of the technicians, doing side jobs. I don't care what they do on their own time, but if they're wanting to use my tools and my vans and different things, that's kind of a gray area.

I have let people in the past if it's for their moms and dads and different things like that, I'm gon na be honest with you. I can make more money. Even when I wasn't a business owner, I could make more money at work as opposed to doing side work, and if that makes sense to you because side work just it brings a whole bunch of things that you don't realize our problems like, for instance, what's the Liability of you doing a side, job yeah. Most people can get away with a side job and not worry about liability.

But what happens if you fall? What happens if you get hurt who's gon na pay? If you get hurt on the job on a side, job workers comp in gon na pay - for that I mean so how's that gon na work, you know, that's that's one of the things that I just never really made sense to me now, I'm not saying I Don't help friends out. I will help friends out all day long. I will help my mom out most of the time. I don't really charge people unless it's like some giant thing.

I might charge them for the parts and different things. It just depends. Okay, so I'm not a fan of side work myself, I'm not crucifying you. If you do side work, it's just it's more of a headache to me and and to be honest with you, we usually have plenty of work to do at our normal job and I'm sure that we could get some overtime and different things as an employee and Probably make more money as opposed to doing side work.

So that's just my personal preference on it. So Adam go ahead. Dude! That's fine! Guys, Adams, gon na post, his a Facebook group link in here so go join his group, I'm cool with that guys. I don't mind if you guys want to talk about groups and different things.

Just talk to me before. Let me know okay, so that way we don't spam the whole group with with stuff - but I know Adam and it's all good if he wants to post something in here, it's cool, so thank you very much royal wins. I really appreciate it. Okay, so it says how much hack work from other texts.

Do you see sorry if this has already been asked, I just jumped in Royal, I see hack work like crazy. Most of my videos from the last couple months have been at a new restaurant that I took over and some of the hack work like go. Look at the Kai rack, blue video. Oh my gosh dude! Some of these.

Some of these things are just nuts and then I I took over that same restaurant chain this last summer just before the summer and the air conditioning stuff was ridiculous. I mean it's good for me as a business owner, but it was just nuts man I see so much hack work. I try not to do that. I'd be interested to know, though, on the flip side, if someone took over one of my restaurants, how much crap they would talk about me, I'm not saying my don't stink cuz it does, I'm just saying like.

Would it be the same like? Would they think that I'm just as big of a hack as the last guy that I thought was a hack? I I'm always interested in thinking what other you know hearing what other people think about my work. So, okay on the delfield electronic temperature controller used in the under counter the fans run on three minutes and off three minutes when the compressor is not calling have you ever ha Doug brown. Okay. How can I say this without getting myself in trouble every single time? I am NOT a fan guys, okay, I do not advise you guys to do this, but I'm gon na be honest with you right now on the delfield Danfoss digital controllers, the stupid fan, evaporator fan on and off thing.

This is a reaching cooler. This is not a freezer, they cycle the fan motors on and off, based off of an algorithm that they have inside the clock, and I think I mean inside the temperature controller and I think it's the stupidest thing they ever did. And yes, I have done that and I do that quite often, okay, Doug yeah definitely dude. I hate that thing.

I've even had the factory to tell me to do that, but I'm not advising you guys to do this. Okay, I do not advise you to go in and try to re-engineer boxes without talking to the factory purse, but I have had the warranty department tell me yeah, let's just go ahead and hardwire those temperature controllers so that the fans run now. I will say very, very cautious: don't ever do something without talking to the factory and if it is an r2 90 system do not even attempt to try to change anything about that system. If you're working on an r2 90 system, I highly highly suggest that you always put in the factory parts you always order them from the factory.

Even when it comes down to electrical cords you put in the factory parts, I'm not a fan of the r2 90 refrigerant units. I think that we're gon na have some problems in the future. I work on them all day, long, I'm not afraid to, but I just I think, we're gon na have some problems in the future and I think a lot of fingers are gon na be pointed if one of them ever catches on fire so make sure that You have put all the factory parts back into that unit if you've ever worked on it, because you don't want those fingers being pointed at you, so I am gon na go ahead and remove that one. Okay, have I ever used true tech tools? True back, I was thinking of getting it.

It's like 600 bucks and do I recommend Tripoli, vac people at my company say it's a waste of time, okay, Brian or just did actually not Brian or Jeremy Smith on the HVAC school website. Just did an interesting article about a triple evac. Yes, I have done triple evacs in the past, but again I was always taught that they were effective. So it's an interesting article.

I suggest you go over to HVAC our school and look up one of the most recent tech tips sign up for their daily tech tips, there's one where they just did triple evac and it basically debunks the myth of how good a triple evac is so interesting. No, I have not used the true-blue evacuation kit. I've thought about purchasing it, but i just haven't done it yet. So one of these days i'll pick it up and do a review.

I definitely think it's gon na be worth the money for sure.
