Well, hey guys, Howard, I think there's, ladies that watch this too. I don't know, I don't mean it in that way. Okay, so hello! Everyone! Hopefully you guys, are all doing well. It was an interesting week last week for me, to say the least, that video that I released Saturday about the walk-in freezer debacle actually happened Friday night.

I got that all edited and had it uploaded Saturday night. So that was a crazy into my week last week and it was definitely challenging but anyways. We, we just move on right and we just kind of roll with the punches and deal with it. So I went back today this morning.

If you guys, don't you know, I've been trying to post a little bit more on like Instagram and Facebook and stuff. I don't do a lot of posting on those social media platforms, but I've been trying to a little bit more. So I had, you know, posted something there that I went back to follow up and the compressor was still running so across my fingers. I think I did something right, so that was definitely a very stressful one and I'm definitely going to cover some of that stuff.

Inside the stream tonight I got a lot of questions about that. Why did I do it this way different things, and I will definitely get to that. Excuse me: hey thanks, Zach. I really appreciate it.

Man - and I also will get to you - guys's questions and questions from comments and emails. I got all kinds of them. I got a little cheat sheet in front of me with all the questions and different things and we'll see how this goes and Zach. I heard you talking about the new stream thing with YouTube and I actually did the switch over and went to the the new YouTube.

Whatever you know, platform or whatever, and I'm seeing the new stream thing and I like it, it's kind of cool. It actually shows the chat right there and yeah that's pretty cool, so I can actually see the viewers now which, before I could never see. Justin would always tell me at the end like. Oh, we had this many viewers and anyways.

It was I'm kind of going off on a tangent there, guys, hey Isaiah, how you doing but cool you got 973 subscribers very cool, but I'm happy for you. So so I am going to get into this guys and then I'll get into some. Your guys's questions, like Justin, my moderator, says, try to put your guys's questions in caps, lock. Sometimes these these stream, you know chat things go by pretty quick.

So if you guys put your questions and then we'll try to get to them and again, like I say, every single time, don't hesitate to repost your guys's question: you're, not gon na piss me off just put it in there and I'll try to get to it. That way, cuz sometimes there's so many things that I can't scroll the way back up to the top. So one of the biggest questions that I that I got well the most questions that I got is on my video that I posted on Friday. So I'm gon na address those real quick so that that particular one - let's do a little recap.

Okay, we had a service call about three weeks ago, one of our other service techs, Brian Summerall. Thank you very much man. I really appreciate that super chat, so about three weeks ago we had a service call on this particular beer, walkin that I made the video on Friday, one of our Tech's Alexander appreciate it man, one of our Tech's, went out there and the walk-in evaporator was iced Up this is the beer walkin and he jumped up in there looked at the electrical section and told me: hey dude everything in there's melted. It looks crazy, and so I told him: okay, don't really disturb anything.

Just defrost the coils get it running and then I would go back out there. Well, we got busy and I never had an opportunity to go back out. There got another service call couple weeks later, which was Friday Friday, yeah Friday afternoon, actually Thursday night cuz. I was out there Friday morning and they they said, hey my walkins, a beer walk-ins I stopped so then I kind of knew.

Okay, I what I was getting into. It was gon na be kind of a project, so I went out there and we started with it like you, guys saw in the video it just was one thing after another. I found electrical problems: okay, fixed all that ended up being a compressor. You guys can watch the video, but the things I want to address is people asking me: why did you change that walk-in? Ok, so what I did was I found that the evaporators for that particular beer walkin were electric defrost.

Ok and I changed the system to air defrost and the question I got, why did you change something that was designed one way and I changed it to another way number one. I don't suggest that you guys do that unless you really really know what you're doing and go through the steps that I did. Ok and I'm just gon na address everything that I changed on that system right now, so I changed it to air defrost and I change the power heads on the expansion from a pressure limiting power head to a medium temperature power head. Okay, but I need to stress that I never changed the coil temperature okay.

That system was never a walk-in freezer again. My confusion was: why did they send electric defrost and put low temp power heads when they're not running that as a low temp unit? Okay, it does not have a low temp compressor and I'm actually gon na pull up the compressor documents to kind of show. You guys my logic and why so let me go ahead and move this over real, quick and I'm gon na close this down and what I'm gon na do is I'm gon na share my screen and I'm looking at the Copeland mobile app for desktop and I'm Gon na show you guys how this works. Okay, so you can use this on your phones or you can use this on your computer.

I happen to pull it up on my phone that day, so I'm going to open up my display capture turn that off and I'm going to share my screen. Okay. So this is the compressor that I had in that system. So you see over here on the left, it's a ZB, 30 KC II and I went to the performance information.

Josh hurt. I really appreciate it man, so I went to the performance information in the Copeland mobile app, and this is the compressor okay. It can be used as two in two ways: it can be used with an evaporator temperature of 20 degrees and it can be used with an evaporator temperature of 45 degrees, and you can go in between those two to our particular system is set up as a Beer walkin and they keep bottled beers and they keep some other liquids inside of there, and that means that we can't get below 32 degrees inside that box. In fact, we really don't want to get to 32 degrees.

We typically want to keep the temp about 35 degrees, so that way we have no chance of overshooting and freezing the product in the box. But I want to stress that before I change the power heads and before I took out the electric defrost, I made sure that we weren't running this as a freezer. Okay, so you can see that I didn't change anything that was gon na hurt the system. When I change the power heads from a low temp pressure, limiting power head okay and the reason why they used the low temp pressure limiting power heads, I'm gon na go ahead and pop off of this screen right here and let's see if I can figure out How to do this, there's that and let me go ahead and transition that back over all right.

So the reason why they used a low temp pressure limiting power head on that system was actually because they were using electric defrost on a medium temperature walkin. So they knew that the the defrost heaters when they energized were gon na bring that coil temperature up significantly because it wasn't a low temp coil. So they were only operating that coil at a minimum of 20 degrees, evaporator coil temperature, and so when they run the electric defrost. You know the temperature that coil might come up to 45 50 degrees and then, if it comes out of defrost, they might have a heavy load on that evaporator and slugged the compressor with liquid refrigerant, because the expansion valves flood or not liquid refrigerant, but overload the Compressor with suction gas - I should say: okay, so they put those pressure limiting power heads on there because of that still not a fan.

Okay, I still don't like what they did, but that was their logic at least that's the way. I can rationalize it in my head why they would put low temp pressure limiting power heads. I still don't even understand the low temp part, because again they aren't operating that as a low temp evaporator coil. Okay.

Now I may not have expressed this all in the video, but this is all the stuff that goes through my head. My head is just like a freaking web of madness when I'm when I'm working - and I don't know if it comes across when I'm when I'm filming but there's a lot of stuff going on. And it's just running through my head and sometimes people like they'll be working with me and they'll say hey: let's do it this way and I'm thinking no and they say well. Why not, which I don't mind if people ask me why not I try to explain it to them, but sometimes I just can't think like.

I know we can't do it that way, but I quite can't come up with the answer right now, but just trust me: let's do it my way, okay, because I I think things through and then I put them in the back of my head and then keep Moving on, but I have a reason you know so anyways I'm going off on a tangent there, but so I changed the system over put the regular power heads on there, because I noticed that we were running really low, suction pressure, but the power heads weren't, the Only problem, I also found that that suction strainer I mean that strain around, that TXV was plugged up too, and that was definitely an issue causing some low suction pressure and the strainer being dirty is just because of poor refrigeration practices by the previous contractor, and this Particular customer I took over a bunch of new restaurants with this customer about a year and a half, maybe a year ago, and I've gotten a lot of video content because it's been a mess of converting systems and fixing things and you know putting them back up To factory specs and there's still stuff that I'm finding it's kind of a mess, so so that was one of the biggest questions I got was. Why did I change it to a medium 10th power head? I'm gon na overload the compressor, no I'm not because the compressor is a medium temp compressor. That was the confusion that I had, and I did look that up before I jumped into that. To make sure you know because had that been a low temp compressor and I converted it yeah, we could have done some things.

We could have sent too much gas back to the compressor. You know we might have needed a CPR valve and whatnot okay. So I appreciate the super chats that came in you guys are awesome. Okay.

The other thing I want to address is on the last livestream. I had mentioned that I was going to give away some shirts. Okay - and I did I got ta say it was that I was - I was blown away by the amount of people that had shirt requests in there. I must have sent out over a hundred shirts and I'm pretty much out guys.

So when I do get a new order, we'll figure out a way to distribute them one way or another. I don't know how I'm gon na do that. I tried to apply with Amazon merch. I got denied for whatever reason so we'll figure out another avenue to distribute some shirts and help you guys out, because I know you guys want some so we'll figure it out one way or the other.

But I really appreciate all the paypal donations that you guys did that really did help me with that, because the anyways appreciate it, but yeah we're pretty much out for now. I do have still a few email requests that were already sent. I haven't emailed them, but I'll try to get to some of them, but I'm not necessarily gon na get to all of them. So if you guys didn't see a correspondence from me I'll try to get back with you guys, but there must have been 200 emails.

They came through and I'm still trying to go through and categorize them and everything so but we'll get to it. Okay, but I really appreciate that all right, so the question I see in the chat right now is Frank. Bradley asked me: what do I generally like to see for super heat on a walk-in freezer running 404, a so the the refrigerant really doesn't matter as far as the super, he goes. Okay, because we're gon na try to get the most use out of that evaporator coil, so the lower the superheat, the more efficient that evaporator coil is so typically on a walk-in freezer.

If it was, you know that the average there's all kinds of variables in this, but the average superheat you're gon na see on a walk-in freezer is about 6 to 8 degrees. Evaporator superheat is what you're going to want to see now, depending on the system. We may be able to run it colder if it has an electronic expansion valve. We can probably run it a little bit colder.

Something to remember when we have a superheat target general rule of thumb on a walk-in freezer. Six to eight degrees on a walk-in cooler is like eight to twelve degrees. Okay, that's a general rule of thumb, but there's a lot of variables in there. Don't just take that you know and run with it.

Okay, but a lot of times. We have that broad number, six to eight degrees, because some of our expansion valves can overshoot. So we tend to say: hey. We don't want to go any lower than six, because when we're eight, sometimes when we get down to six degrees superheat, that valve might actually be opening and closing and we might get down to four degrees.

We might get up to eight degrees, so they give that as kind of a buffer zone to go with that six to eight degrees. When we have electronic expansion valves, we actually have a tighter control of our superheat and we can tend to run them a lot lower and be able to control and not worry about overshoot as much and then not worry about our compressor as much so. I've noticed a trend of manufacturers running with really low. You know, like, let's say four degrees superheat with an electronic expansion valve or six degrees right on the money, and you know they don't never really.

You know moves up and down very much okay, because the electronic expansion valves are so great and controlling their their range. The downside to the electronic expansion valves is we, as technicians tend to be a little sloppy and don't follow proper refrigeration practices. So, in my opinion, a lot of people complain about the electronic expansion valves because huh, that's weird, my my software showed that the screen went away for a second. Let me know if you guys get like a buffer or something that was interesting, yeah.

That was weird anyways, so yeah, I tend to notice a lot of problems: people complaining about the electronic expansion valves because of poor refrigeration practices, people not pulling proper vacuums, people not purging with nitrogen. You know when they're brazing and different things like that. So alright, let's see what else we got going on here. Yeah watch out that night BOTS gon na get you guys so he's being kind of like a little ass today.

So alright, so I got that one. Let's see what else we got in here: videos yeah! I don't know if I like this, because I'm getting more warnings on this stream right now and I don't know if they're actual warnings or what so so see you have a question about summer and winter charge Dave Tatro. What is your question? Dave go ahead and answer it and I'm going to address another question: throw it in a caps, lock there Dave and then I'll try to get to it. Okay! So let's see what else do I got on my list of questions that I want to answer here? Okay, okay, so I had another good question, so the person emailed me they said hey when you found that the expansion does.

When I found that the expansion valves on that beer, walkin weren't working properly, he asked me why didn't I change the whole valve, and why did I just change the power head? Okay, I'm gon na tell you that more than likely, I'm just guessing at these numbers, but I'd, say almost 90 % of the time. A problem with an expansion valve is gon na, be the power head. Okay, unless you suspect that there's a lot of contamination in the system, most of the time, expansion valves will last longer than the system and if there's a strainer in the valve, it'll, usually catch stuff. So majority of the problems that I run into with expansion valves are typically power head related and a lot of times in refrigeration.

We can just change a power head really quick and our valve will be working. Fine, okay, clean the strainer change the power head and move on I'll. Give you another tip. I've done this before, if you suspect that there's something wrong with the spring or the pan, or something in the expansion valve.

You know, depending on your situations, if you can find the exact same valve, you can actually just change the guts. If you, if it's like, if you don't, you need a hot work permit or something like that, and you can't do it. You can actually just change the guts of that valve. Just make sure you assemble it back together correctly and torque everything down, you could pull the whole insides out and put everything back together and you know move on.

So that's another tip if you guys wanted to I've done that before in weird systems, but majority of the time the springs, they don't typically fail in the expansion valves and the pushpins and stuff they don't usually fail unless they're gummed up with gunk or the valve Is flooded with, and you know weird things for the most part, you can just change the power head and move on so so what effects have I found in the field from previous text not flowing nitrogen? So one time I was, this was a little bit big for my britches as far as work goes, but I used to do a lot of warranty work for Kai rack manufacturing here in Southern California because they used to be located here in Southern California, so anyways. I was sent out to a big University in my area and they had a giant rack on the roof. That was a little bit beyond my comfort zone of you know to work on. It had a bunch of parallel compressors inside of it, and it was just kind of like a little intimidating and it had a dick cilantro ler and it was kind of like whoa.

I've never worked on anything anyway. So I was there to work on a little reach-in fork, Iraq, and so I went downstairs and the expansion valve wasn't working properly, so I condemned the expansion valve and in that situation I believe I tried to change the power head and it didn't fix it. So I went ahead and changed the valve okay moved on, went upstairs to go change the dryer and found that this had core dryers. There was no dryers in the system and on top of that inside the core shell was, I could pull handfuls of soot.

Okay and in carbon flakes out of the the the the the core dryer shell, but there was no core dryer in there and I ended up getting cores putting him in that system and ended up having to go back out. A week later same problem. Expansion valve failed again. Okay, this time I went up to my course.

They were plugged with with crap. Okay, so pulled the cores out again change the expansion valve again put new cords in there I went out again changed another expansion, also there's three or four times. I went out and changed expansion valves on their little region because the previous company that was doing the installation did not flow nitrogen in that system. Now lem me explain something.

I'm not gon na lie to you guys and say that I have flowed nitrogen on every single system that I braised and no, I would say that I flow nitrogen, probably on maybe 45 to 50 percent of the systems that I braised on. So I am NOT a perfect tech, okay, I don't do it all the time, but there's a time in place when you know you need to do it and when you're doing a big system like that rack system that had they must have had probably 30 cases On that thing it was huge. Okay, there was walkins on it all kinds of stuff, and it was everything in and another thing too. They did a really bad job because they didn't install isolation valves.

So in order to change those cores and enable to change the expansion valve the first time, I had to pump down the entire system, so that was like three walkins, a bunch of regions, cases different things, and then I installed isolation valves on my equipment that I Was working on and then from that point forward I could I could work on my equipment, but it was still a disaster so anyways I digress. So as far as that goes Zack, that was probably the worst system. So you know that system had tons and tons of piping and they were not brazing with nitrogen and it was plugging everything up and they didn't have a core shell. In there it was just a nightmare so that did the carbon flakes were just crazy in that system.

So, let's see what else we got going on in here, do I charge them each time I went out heck yeah, I did yeah. I definitely charge them every time. I went out because that was not my problem. I was there as a warranty, so I was charging the manufacturer.

They were paying me. They were pissed, though I think they probably back charged the customer, because the insulator they probably back charge the installation companies probably what they did so so tips on finding out receiver capacity when it's not printed on the receiver tag. There's a couple different methods: you can do, you can measure the receiver and you can do an estimation based off of another receiver size. If you can't get it, I'm sure that you can calculate the internal volume, but that's a little bit too much math for my head.

So what I'll typically do is measure the receiver, the height the width and the depth, okay kind of, and then compare it to something else. That's similar in size and that'll. Give you a get you in the ballpark. Okay, you can go to one of the manufacturers.

United refrigeration actually has a really good on their app or on their website. You can log in to their website and their parts catalogs on there, and they do a really good job of having equipment specs so like. If you look up a condensing unit like a heat Kraft, condensing unit it'll, tell you the pump down capacity of the receiver and so that that date, United, has really good information. Even if you're not shopping there, you can still use their website.

They got great information for figuring out receiver, size and receiver capacity. So, let's see what else we got going on here, hmm, what sort of our hourly rate do we expect in the US UK for refrigeration engineers, roughly between thirty six thousand and forty six thousand a year topping okay, so you're talking about salaries, it really varies across The United States here in Southern California, you know a journeyman tech depending on the specialty, if you're, just working in regular restaurant refrigeration, but you you know your you can probably make anywhere from thirty five to forty five an hour. If you are supermarkets, I imagine you can go up from there, but I would say the the journeyman scale for the most part, unless you get into some crazy stuff, is probably in the 35 to 45 range. So you know, depending on overtime, you can make an excess of 100 grand, but you got to work your butt off, so you know that's but it'll change everywhere.

You know across the United States, depending on the areas and stuff that you're in do. I ever use the recovery machine to recharge a large system. No I've actually never done that before I've never used a recovery machine to recharge a large system. I know that nav acree cently came out with their their recovery machine that'll also charge the systems.

I've thought about using a recovery machine to charge something on a big system before you know when I know exactly how much refrigerant it takes I've thought about it, but I've just never done it before. Usually what I do is I pull the system into a vacuum. Hookup obviously do the proper vacuums so, for instance, the beer walkin that I worked on. I pulled the proper vacuum.

I was hooked up to the receiver and the receiver was pumped down. So that means that the valve on the outlet of the receiver was front seated and then what I'll do is I'll? Take my refrigerant cylinder and I'll blow, although I'll just dump as much refrigerant into the receiver as possible without the system running and just let it take, you know so, for instance, that wok in that beer walkin. I think if I remember I had another tech on the roof with me, so I think I dumped in 12 pounds of refrigerant just from having my tank being warm sitting outside. It was, you know, 90 degrees outside or something like that, and I just basically dumped as much refrigerant into the receiver as possible.

Then I open the system up and then charge the remaining 11 pounds or 12 pounds. I think that system took like 25 pounds, so I dumped the remaining refrigerant through the low side and metered it in so, let's see what else we got in here. Let's see how old was I when I started in the trade, so I officially started when I in 2002 is when I officially started. I was eight nineteen nineteen I think, and I'm 36 now I think yeah.

I think that's about right, but I grew up in the trade working with my father. So from a young age junior high school every summer, I was out in the field funny enough. I actually have said this before, but I hated this. I told my dad.

I don't want to do this, this is horrible, it was so hot outside and and all I ever did as a kid was just go up on the roof and change filters and change swamp cooler pads in the middle of the summer. It was so hot and just miserable, and I hated it ironically. After high school, I went to work for a body shop working on cars. Just really wasn't my gig, so I worked there for about a year after high school and then came full time in 2002, and here we are 16 17 years.

Something like that. So it's been a good run. I really like it so alright, let's see what else Dave Tatro, you said: you're confused. You saw that I was saying to add extra charge in the summer, clear, the sight, glass and add a few pounds.

If the unit has a headmaster, you would not be flooded. Cool okay, so I yeah you're a little confused there Dave. So a system that has a head pressure control valve requires more refrigerant than a system that does not have a head pressure control valve in the wintertime. A head pressure control valve and/or, a headmaster will flood the condenser, so basically it backs the refrigerant, the liquid refrigerant up into the condenser and at the same time it bypasses the condenser and allows the refrigerant directly off the compressor, the discharged gas to go right into The receiver, the receiver, has to have extra refrigerant for this process to work so there's always extra refrigerant.

We call it the winter charge sitting and the receiver waiting for this to happen. Then what happens is that hot discharged gas, the vapor, essentially pushes down on all that extra liquid refrigerant, that's in that receiver, and it pushes it down to the expansion valve okay and out the same time that vapor is gon na turn into a liquid. As it drops into that receiver and then it's just going to keep going so that's in order for a head pressure control valve to work. The purpose of a head pressure control valve is to maintain a pressure drop across our expansion valve ad and thank you very much men, so the the I got distracted there.

Oh, so the purpose of the head pressure control valve was is to maintain a pressure drop across that expansion valve the expansion valve, especially on a thermostatically-controlled expansion valve okay. This doesn't apply so much to a electronic valve, but a thermostatically-controlled expansion valve requires a certain pressure drop across the valve, so that means on the high side. You have to have so much of a difference between the low side for that valve to work properly. The refrigerant has to be fed through at a certain rate for that valve to meter properly, okay, so the head pressure control valve is there to increase our head pressure and maintain a pressure drop.

So if we have a system that has a head pressure control valve, we have to add extra refrigerant, we're not removing that refrigerant in the winter or the summer. If the system was designed correctly, it just requires more refrigerant than a system that doesn't have a head pressure control valve. So hopefully, that understood or explains that a little bit more and I have said that as we get a little bit closer to the fall, I will be doing some videos and I already have some on my channel but I'll be doing some new videos explaining head Pressure control valves and their operation to get everybody ready for the winter time. So, okay, so Ralph Allie Lee asked if I've seen a lowboy two-door that doesn't have evap coil the box walls freeze and it has a little square fan in the middle.

I've seen something like that before I'm not a fan of those like a static box. Yeah I've seen some weird stuff. They never work right in a hot Amy and they never work right in a high-volume kitchen. So, let's see what else? Okay, I'm gon na go to a couple more my questions here and, let's see okay, so I had a person email me and he's a young guy coming into the trade and he says he's having a hard time getting people to give him a chance.

Getting people to, and I'm kind of, probably paraphrasing what he was asking me but he's having a hard time getting people to give him an opportunity to come. Work for them and to learn - and I'm gon na say that that is a very difficult thing, because I bring people into my company too, and it's difficult to give someone a shot. Because one thing you have to understand and I'm and I'm gon na talk as a business owner first okay, is you have to understand that? Okay? So if I bring an apprentice into my company and he's gon na work with me, I'm gon na dedicate time. My time to teach him okay, and especially, if he's coming in as an apprentice and he's gon na ride with me, I'm gon na dedicate my time and essentially I'm signing up to lose money on him for the most part, because there's gon na be a payout At the end, if I train him properly, you know, yes, I may lose money for the six months or a year or whatever it is that he's riding around with me, but eventually he's gon na be trained and ready to go, make money for the company.

So that's the business side, okay, so we have to think about that and when that also comes into play, we have to think okay. Is this person worth spending all that time and money on so first impressions mean a lot because when you walk in the door and say hey, I need a job. My mom says I got to go to work. You know I'm frustrated, but hey can I come work with you? No you can't, because you don't show Drive, you don't show initiative.

Now, I'm not saying that the person that asked me this question isn't showing driver initiative. I'm just saying the things that we go through as a business: okay, we're taking a gamble, hiring someone and potentially losing money for six months to a year, whatever the apprenticeship is to have the person walk out the door at the end of the you know, in A year and say, oh yeah, I found some little pay me two dollars more an hour. Oh, that's great thanks a lot because you know here we are as a company, so these are the things that you have to go through as a business owner. Now as a person, I look at everybody, none like man.

I got to give that guy a shot. You know because he just wants to learn and - and we try to do that as much as possible, so to get back to your question here. What are some tips that I can give you as a newbie okay number one. First impressions mean a lot when you walk in that door.

You need to be confident, don't be nervous and if you don't know the answer to something: that's: okay, okay, sometimes when people come into my office and we're going through an interview, I may ask them questions. Okay and it's not that I'm looking for the right answer, I'm looking to see how the answer did the answer with confidence: did they were they truthful and saying? Hey, I honestly don't know the answer to that, but I will figure it out. That's the answer. I'm looking for okay, if they can't answer it, I'm looking for them to be honest with me and say I don't know, but I can definitely do some research.

Okay initiative is another thing you can show. I would suggest you know if you walk into someone's door of a business and you're going to work for them, and you know you walk in the door and you say: hey I've been in trade school for a month. Now I'm taking a class at my local community college. This looks really interested in to me I'd like an opportunity to come work for you.

You know that's that show them that you're interested okay show them that hey when I go home at the end of the day, I'm reading I'm looking on the internet, I'm researching I'm watching these videos. I'm reading these articles, you know go to find local trade organizations. Rses, I'm part of my local RSES chapter. They do free meetings not everywhere across the United States, but we do have chapters all over the place.

But here in Southern California we have two chapters that pretty much encompass, Los Angeles and the Inland Empire and that's a big area and we have free training meetings once a month where you can go in there and get free classes. And you don't even have to be a member to go to the meetings. Okay, things like that, if you show the company that you're going in to work for or that you're applying for that, hey, I'm showing you initiative. Okay, also, you know, don't go in there with an attitude.

Don't expect them to give you everything, don't go in there asking them what they can do for you, okay, at the same time, they should never expect you to bend over backwards. Okay, but it's it's got to be an equal give-and-take between the company and the technician that's applying to work for the company, so I'd be happy to that. I'm addressing the guy that sent me the email I'd be happy to address some more questions. If you have them feel free to send me an email and I'll try to address it, a little bit more okay, let's get into this chat here, a little bit yeah.

I learn how to carry tools. That's a good idea, but I mean okay, so I'm gon na I'm gon na go. I saw that comment come through, but here's another thing when you do get the opportunity and you go to work for someone, don't stare at your phone all day. Long! Okay, don't be looking at your phone answering personal phone calls talking to your girlfriend talking to whoever you're there to work.

Okay, ask questions about work when you're riding in a van ask questions: hey man, you know we worked on this yesterday. I'm confused ask those kind of questions. Okay, be ready and pay attention to what you're doing the best thing you can do as an apprentice. That's watching someone work is be ready for the next tool that they're gon na ask you for so.

If they're welding in a compressor, brazing and compressor doing whatever you need to know what they're gon na need in two minutes, you need to have it ready. You need to start thinking ahead because that's what's gon na train you to become a better technician. So that way, because when I'm brazing in a compressor, I'm paying attention to what I'm doing, but I'm also thinking about what I'm gon na do next. So as an apprentice, you need to do the same thing be ready.

So when I turn around and say hey, can you get me this handed to me because you already knew? I was gon na. Ask you for that. That's a tip that I can give you that's gon na help you excel and succeed. Same thing goes for a technician.

That's been in the field for 20 years ever and I'm not saying I meani better than anybody else. Okay, but I constantly strive - probably more so than I should to do better the next time. So when I finish a job, an installation, job or a service call, I reflect on it when I'm driving home and I think how could I have done that better? What happens if I would have done this before I did that reflect on that stuff? Don't just shut your brain off and go home. Okay same thing goes for a technician in an apprentice.

You've got to think about stuff, okay, so, let's get to some other stuff. Here, let's see what else yeah I see, the chat is going crazy right now. So, if I'm missing questions guys, you know post them in the chat again, we'll definitely get them. I see that quite the thing that says the phone is them all.

Is a millennial thing, and that is so true John. It is but at the same time, even the the guys that have been in the trade for a long time once they realize how convenient how cool the phone is and you can get Facebook on it. It's really easy to stare at Facebook all day, long. Okay, I find myself because I get emails and questions and whatever all day long, I find myself mentally having to say no, don't pick up the phone.

It's not ringing. Put it down pay attention to what you're doing. I have to tell myself that, because I'm getting notifications from you guys in questions - and I try to answer - I want to help as many people as possible, but I also have to know it's time to put it down. Okay, so let's see what else we got going on here, do I think he'll? No, I don't think I'm better everybody else, Timothy! No, sir! I do not.

I probably look at myself. In all honesty, I think of myself as less than everybody else, and I'm striving to be better. That's that's how I honestly look at myself now a therapist or something is probably gon na. Tell me that that's wrong and I can't value no devalue myself, but that's how I that's how I am I'm.

I would say, I'm insecure, because I'm always thinking that I'm not doing good enough and I'm not good enough. And how can I be better? That's honestly how I feel - and I in no way no way possible - do I think, I'm better than anybody else. No, what is the biggest store? I have worked on biggest store. That's a good question.

I don't do any supermarket work, so I just do restaurant work. So I mean I've worked on some big restaurants that have a lot of equipment. You know stuff like that. I I don't know what the biggest one is I'd say.

Maybe you know the restaurant probably has 15 or 20 ACS. Some big, like I used to do work for, like I can say, because they're not even around anymore, used to work like game works and stuff like that. So they used to have a lot of packaged units and then they had a lot of refrigeration equipment and different things, and I've done work for a lot of other restaurants, but no big supermarket stuff. I don't do any of that.

So, let's see what else! Okay, all right, let me get to my questions here. Okay, really good question that I had, and I wrote down, was how okay, when I'm recovering the gas out of a system that has a known leak on it - and I know some of you guys are going to know the answer to this already. But the person had asked me: how do you make sure that you don't pull air into the sit into the recovered cylinder with refrigerant in it? And that's a really good question so and what we're getting at is is we've got a system that has a refrigerant leak. Let's say it's on the low side of the system: it's got evaporator leaks and we're going to change the evaporators.

This disk goes with pumping the system down and/or recovering the gas. What you simply do is you just recover to a very slight positive pressure? You make sure if it's on the low side, especially that the system never goes into a vacuum, on the low side recover to about 1 to 2 psi, and then you call it good if you're saving the refrigerant okay, if you're not saving the refrigerant, then you Go to town, let that thing pull down as far as possible. What you can also do is is shut your recovery machine off for ten minutes. Leave all the valves open.

Let the pressures come up turn it back on for a few minutes, pull it down to about one to two PSI turn it off again. Let it come up. Do it a couple times and eventually it won't rise very much anymore, and you can't really do too much more than that. Okay, so let's see what else we got okay, so someone had asked me: oh no, this! This is another one.

I wanted to address this. So one of the Facebook groups someone this one got a lot of people pissed off and angry, and whatever someone posted a picture, it was like a meme or something like that. I just thought it was an interesting one to address and it it showed something of like your boss was out on the lake and joined the day when you were working overtime and it was like. You know, implying that that was a problem.

I'm gon na address. This in two different ways as a technician and as a business owner. Okay so bluntly, I'm gon na say that what I do on my personal time is nobody else's business. That's how I'm gon na say it as a business owner like it really isn't any of your business now.

The compassionate side of me is gon na want to rationalize and explain its people. Okay, you know the first thing I want to say to that technician: that's upset that his boss is out doing. Something is why are you upset? I mean if you're so upset that that's making you angry then move on it's as simple as that. If you don't like where you work and your boss is being a punk, maybe he has been upon, maybe your boss is driving flashy cars and making you feel inadequate.

It's it's really simple move on move to the next company. Why? Let yourself be angry if you're angry about what a condition or an environment that you work in. It's simple move on simple. As that now a lot of people don't realize that as a business owner there's a lot of expenses, okay in business owners, we really don't have to rationalize this and explain it to people, but sometimes you know it helps to let people know there's a lot of Costs that go in involved in bit in business - and you know there's times when as a business, the money's not there and we're still paying our technicians.

You know at my company, the technicians have never never never gotten missed a paycheck. Okay, even when times were tight. We we pull out of our personal accounts, you know and pay the technician, I'm not kicking aside, I'm just explaining both sides. Okay - and I just I thought it was an interesting thing, but I just I really took like I thought that was funny that the person posted that meme like he was angry, that his boss was doing something it's like.

Why does it even matter it's as simple as move on? If you don't like it, move on to the next thing: okay, that particular business, you know, there's a lot of stuff that goes into a business and a lot of expenses. Okay, you know, so it really. It really kinda. I thought it was kind of funny now as a service technician sure you know, if I could imagine that I would be upset.

If I went to work for a company and every day the boss pulls up in a flashy car, and maybe I wasn't making as much money or something like that, but do something to change your situation. That's how I would approach it as a service technician. Take the business ownership out of the picture is, I would maybe go to the boss and say: hey look man, you know what do I got to do? How can I help the company so that way, I can make more money. That's a great way, and I that not segues into another question someone had asked me recently to you know: what's a good way to ask for a raise, and that was exactly my response - is don't go in there and ask for more money.

Go in there and say hey, I would like to make more money, but I realize that you know I could probably be doing more. So what, in your eyes, could I do to improve things that the company that could potentially make me more money? Ask what you can do to make more money instead of just asking for the money? Okay, so I'm kind of going off on a tangent there. Let's see what else do I let my technicians do side jobs if they are not using my company name? That's a really good question and that's a really really controversial question. Okay, so it's none of my business.

What a technician is doing on his own time, but I will preface this with saying: don't don't ever make me question the fact that maybe you're using my tools or my vehicle or my name, to do something? Don't ever let whatever you're doing on the side come back to me, don't ever let whatever is going on over there. You know make you look bad because guess what? If, if you do something you do something wrong or do somebody wrong on your own time? It affects your work too, so you know. Do I care if an employee does side work? I mean I know not really as long as it doesn't compete with me. Okay, because yeah, if they're going out and trying to bid on jobs like heck, yeah, they're fired instantly.

Okay, if they're trying to bid on jobs that I that I'm trying to bid on or something like that, yeah easy-peasy they're done. Okay, but you know I've in the past, I just asked the people to talk to us. Okay, like hey, you know sometimes I'll. Even let him use our tools or something like that.

Okay, they call me and say: hey, I'm going over to my aunt's house. I got to change a package unit from my aunt. Would you mind if I took my van over there, I'm not gon na say that I'm gon na say yes every time or no every time, but I might even let him do that. You know it just depends on every situation, so that's kind of a hard question to answer like you know, yes or no, because there's a lot of variables involved in it.

But I said especially, you know when it comes to the reputation of the company and different things like that, so hopefully I answered that a little bit all right. Let's see what else we got going on here, um. I am going to go to my thing right here, so oh, this is another good one too. I got this.

This was from a couple weeks ago, one of my popular videos that I had where I changed: a compressor on a small little five ton or six ton package unit, and you know everybody's like. Why did you fix that unit? You should have sold him a new one. Why did you and I changed the compressor because it was making a loud noise and the discharge line had rubbed out and everybody was commenting saying all that compressor was low on oil. You could have added oil and it would have been fine.

That's great. You know I got ta say also. You guys have to understand that. There's a lot of things that go into these videos, that you guys don't see.

Okay and there's a lot of things that go into the call, I should say that you guys don't see. I have to make sometimes an educated guess when it comes to a system. Okay, I walk up to a system, and I know that that that compressor has been running. You know loud for for the last two PMS and then now we have a refrigerant leak.

Okay, so I chose to go ahead and replace the compressor and fix the leak clean, the condenser and be done with the system. Sometimes you have to evaluate things. Yes, I might have been able to pour oil in that compressor and maybe it would have quieted down and maybe not be vibrating. So much okay, I shouldn't say vibrating, because the vibrating was a whole different thing, but maybe it would have quieted down.

But at the same time, my customer - they don't want to spend money for no reason, but they also want it fixed the first time and they want to be done with it. So for me to go in there and say hey, I could probably pour some oil in that compressor and then we'll see what happens they don't want that? Okay, they don't want, they just want it to be done and fixed. So in that situation you know I had to make a decision like hey look. This system has a refrigerant leak.

I know it's been making a loud noise for the last couple. Pms, the compressor discharge line is, or the compressor itself was vibrating, so that to me on a carrier as a dead giveaway. I spin on the train units to train units. Some of the scroll compressors have a problem with liquid discharge lines, cracking because the way they pipe them in different things, but a lot of times it has to do with the compressor having something wrong inside of it, causing the vibration okay.

So in that situation I decided to go ahead and change the compressor, because I you know knew from experience that hey this is gon na become a problem. I just want to nip it in the butt, we'll change the compressor, the amount of time and labor involved in having to come back, recover all the gas and still change the compressor after I spent all this time on, it probably would have exceeded the cost of The compressor, so it's easier just to do it all at once and move on. So let's see what else do I use three-phase monitors for correct rotation in phase failure? Paul Jamison, it just depends: I've used phase monitors in the past where I've had voltage problems. I typically work for like chain, restaurants and stuff, so a lot of times they're not wanting to spend a bunch of money.

You know to put power conditioning on their equipment, but I have used phase monitors and I've thought about using them more often, but it's just sometimes it's a hard sell when you're dealing with chain, restaurants and different things like that. Some some of those people don't want to sell. They won't want to buy that stuff. Okay, they they don't want to get 40 years out of their equipment.

They're. Just looking at tax write-offs a lot of times, you know there's a whole other side to working in especially chain restaurants, because they basically operate their equipment, equipment off of a depreciation timeframe, and you know when they, when it's time to buy new equipment. It's just another tax write-off and so they'll use it until the depreciation is gone then they consider replacing it so that's a whole nother whole nother thing: let's see what else any thoughts on starting a YouTube channel, you're thinking making one for a day-to-day reefer tech vlog. I mean you know: a lot of people are watching youtube videos, so anybody that's that wants to start.

When I encourage you, I'm gon na say you better have some thick skin, because the comments can be pretty brutal, sometimes, but I'm not trying to talk you out of it. You know, go for it. There's there's lots of room on YouTube for streaming channels and all that different stuff so go for it. You know the more content, but I highly suggest that if you are gon na put content out there make sure that it's accurate and correct, because, especially nowadays, the younger generation is jumping on YouTube and just paying attention to what they see and trying to roll with It and if you're, given false information or bad information, you know that can become a problem, especially if younger guys are looking up to you.

So have I had anything blow up or has anything caught on fire sure you know the other day I was brazing. I was unswayed discharge line on compressor and there was oil inside the line and it ignited and shot oil out everywhere and then the fire was catching on. I was actually the glycol repair, video and you know stuff happens when, when you're working or when you're braising, you have to be prepared for the worst, and you have to try to think about things before. Like I had said earlier, you know when I'm braising something in I'm thinking about what I'm gon na do next.

Well, at the same time, when I'm braising I'm thinking about okay, am I ready for when something bad happens? You know you have to expect things to happen and I've had motors catch on fire different stuff. Like that, you know you just have to know how to expect and how to react, and the most important thing I can tell you is: you have to learn how not to react. Okay, I've said that before in videos, but that's a really piece, really important piece of advice I can give to anybody, and I'm gon na give you an example. Many years ago my dad was working in, for whatever reason he was braising 7/8 pH piece of copper and it was vertical okay.

So basically the copper pipe was going up and down and he was brazen on the bottom or on the top or something like that, and it happens to the best of us. We make quick decisions and sometimes they can turn out to be bad.
