Hello, how is everybody doing today? Hopefully you guys are all doing well, let me adjust my headphones up. There. We go cool. Well, I hope you guys had a good week since the last I spoke to you.

I've got a couple topics that we want to cover. This evening, and then I want to get to some of your guys's questions - I see that superior you posted in here that I should talk about stress stress. Yes, I deal with that one on a daily. In fact, I am currently dealing with that one right now, because we've got a particularly weird situation at work where we've got like this nuisance service call that is kicking our butt and I've got another tech on it, and it's sometimes it's really difficult for me to Let other people try to fix things, especially when this might be the second time we've been out there.

The stress level that builds up inside my chest is just killing me right now and it's making me to the point that I'm almost sick and I could feel you know I'm sure my blood pressure is really high and it's not good superior had posted something in Here that he had a medical incident, which is not good, sometimes I'm afraid that I'm gon na run into that I'm gon na have you know a heart attack or something like that? It's not good. Do I have great advice for that? No, unfortunately, the type of person that I am is I I wear everything on my chest and I worry about my customers. I worry about my reputation and I worry about you know what people think about me. You know and and it's it's bad it's one of those things that I have to learn to deal with.

I wish I had good advice for it because I would follow it myself. I mean I'm right now, I'm almost to the point that I'm almost shaking, because I'm so like freaked out about this situation that we got going on and it's a you know. I I have control issues when it comes to. You know letting other people take care of things, especially when we can't figure it out the first time, I'm not saying that I'm any better than anybody.

I just. I feel that when I'm, you know like I'll, give you an example so say I'm working with an apprentice and we're doing an install okay, and you know, of course I want to be teaching him something I want to be teaching him. How to do a certain thing like, let's, let's braise the line set in or something like that? Okay or let's braise in the TXV, the anxiety that builds up in my chest when it comes time for him to lay a bead of solder on that TXV makes me just want to take the torch from him and say: okay, just watch me because - and I Realized that I need to let people do things, but it's hard for me to let go of control when I'm so emotionally involved and cares so much about the business. So it's it's stress is a a great topic and I I really need to learn how to let things go, but it's one of those things that is really hard, because I take so much pride in what I do in our business.

You know when I'm doing an install, I'm thinking about the bottom line. I'm thinking about we got to get this job done. The customer needs to be happy. We need to do it better than the last time faster than the last time, and it frustrates me when I think about other texts.

You know not necessarily there's anything wrong with them, but people don't think the same way that I do you know when I approach an installed job like we do walking cooler installs all the time, and I guys I'm not even paying attention to the chat yet. But I will okay, so I'm just gon na finish on my rant and then I'll go to the chat and address everything so before I go any further, throw your questions and capslock: okay, guys and I'll try to get to them and Justin I'll. Try to help me figure it out too. So you know when I'm doing the installs.

You know we do kind of like cookie cutter installs. It's like the same every time, it's hard for me to understand why we can't do them better. Every time. Why do we tend to run into consistently the same problems each time it's like? Why haven't we learned from those problems? It's just something that I I'm starting to get better at realizing that some you know some people aren't going to change, or sometimes you know nobody can be perfect.

I get it it's just hard for me to understand that, because I will break my back to try to be perfect when it comes to doing something. I will bend over backwards to try to make sure you know, and it's it's you know as a business owner. It's hard and even though I understand laws and different things like that, you know when I'm doing an install - and I know this isn't healthy for me, but you know oftentimes. I don't take lunch breaks because I'm busy and I'm working right - and I realize that my guys have to take lunch breaks.

That's totally the law, that's legit! That's what they got to do, but I still every single time when it comes time for a lunch break. They're still part of me that gets frustrated because it's like man but we're kicking butt, we're installing, but I have to step back and remember so. I know there's other business owners out there and I know they have to deal with these same stresses. It's a difficult thing.

I know we have to learn how to let go and let people figure things out on their own, but it's really difficult and it's a constant struggle. So if anybody out there feels the same or runs into the same problems as me, you're not alone. You know it's just one of those things. I don't know the answer.

You know it's just it's just it is what it is. I guess, and it's just one of those things you got to learn how to deal with I've definitely had to learn how to deal with things taking longer than I expect you know, and that kind of stuff and and and again I'm not faulting anybody, because everybody's Different and I'm slowly coming to terms with the fact that nobody can work the way that I work and nobody's gon na have the compassion that I have because you know not only am i a service technician, but I'm also an owner right. So I think about things a little bit different than just a normal person. That's a service tech, so you know, if there's anything, any advice that I can give from my little rant that I just went off on right now is that I don't expect my service techs to be.

You know as passionate about things like I am. I don't expect for them to constantly be, I mean I would appreciate it, but I get it. You know they got to be normal people and they got to do their own thing and everybody's different. You know, but if, if you as a service tech out there wants to know how to set yourself apart is is show a little compassion, you know care about the job and show your your boss, and you know, show them that that uh, you you you know, You do care and you are concerned about making things go faster.

You know, while while getting it done thoroughly and doing it properly, okay, so yeah - I don't know where I'm going with that. I was just definitely a rant. So apologize on that one but yeah. Someone said deep breath, that's true, you know it is what it is.

So, alright. I want to get to the chat and I will address some of these things. So oh yeah bill Burnett, says anxiety. Sucks yeah, it does anxiety is a pain.

I deal with that. One for sure I have the worst anxiety in the world and a lot of times. I don't show it, and that is part of my problem, you know and that I don't show anxiety sometimes because you know I've talked about mental struggles. I joke around that.

I have mental disorders and different things right, but I did go to a therapist many years ago and they did help me to learn how to deal with things and let things out you know for the longest time I just buried things inside and just held it Inside so it does help to talk about things. You know any of you business owners out there. I don't know if you guys are listening, I mean I guess this could apply to normal service text too, but you know I used to keep this stuff secret from my wife because I didn't want her to know. You know I didn't want to involve her in anything with the business and to this day she really doesn't have very much involvement.

She definitely will never have an you know like she'll, never be working for the company. I won't do that. Our company is completely separated. So my wife will never be part of that, just because I don't want her to have to work with me and I don't want to have to work.

You know in the stress that I have to deal with, but the one thing I did learn to do was to communicate with her, and you know I used to try to hide everything, but then what I found was, I would come home and I would be Bitter and I would be quiet - and you know I would explode, I would get angry for no reason at something silly, so I've learned to at least communicate with her when I'm having a stressful day. You know to call in and just kind of vent to her in different things. So if there's anything I can give from the craziness that I go through, I would, I would highly suggest, communicate that's the biggest thing you know just at least communicate with someone. Do I have the answers as to how to not deal with stress and anxiety? No, I don't trust me because I'm still going through it every single day, but I do not have the answers.

I just try to cope with it and move on. I guess and just take it one day at a time, so what try to do so all right. So, let's get to some of these. Ok, yes and I you know, and just like someone had told someone had told yeah stress exactly I see everybody.

So I can see a lot of you guys relate right, whether it be business ownership, whether it be life, whether it be financial stuff. You know anxiety and stress. It's you know I I'd be really interested. I should have a blood pressure machine right here right now.

You know checking my blood pressure. I'd be really interested to know what it is at the moment. I know that as a kid, I've always had higher blood pressure, but I'd be really interested to know. So I'm really interesting but sorry.

I said interesting enough: hey on another note, I have got. I'm gon na do a little video on it, but someone had posted on Instagram. I think her Instagram name is chill or chick. I think, and forgive me if I'm butchering that forgive me if I'm saying where you're from is wrong, but I believe she's from Canada and I believe she works for an industrial company.

I just I see Instagram post every once in a while anyways, so she had posted about something that she was using for her lunches and she was in a mechanical room and she had like this little lunchbox thing and it was called a hot logic mini. I was very interested in it, so I went ahead and checked it out and did some research on it and it's a really cool little device. It's basically a hot pad. Okay, it comes with a glass pyrex dish with a lid on it, and I was doing some reading and the reviews on it were really cool.

And I thought it was really interesting because we're able to cook our lunches out in the field and actually have a hot lunch right - and I know I'm telling you guys about it just so. Maybe you guys would go google search it, but it's really really worth it. Ok, it's it's basically a hot pad and you can cook raw food in it. Ok, so I bought one because I wanted to try it out.

I think it was 60 bucks. You know it's just a hundred and fifteen volt little hot pad and it came with some recipes and stuff, but I tried something interesting today I took a raw chicken breast put it in there because I worked from the off today, so I did it on the Countertop at the office, just because I wanted to see how it worked before I took it out in the field, but I took a raw chicken breast threw in some raw veggies some raw spinach, some raw garlic and cooked it for two hours. There's no settings or anything: it cooks, it constantly at 165 degrees. So after two hours the chicken was completely done.

It was 165 degree temperature. I had a little, you know kitchen thermometer, I checked it and it was bitchin. It was a great lunch. So anybody that's wondering, like I do how to deal with this.

This whole conundrum of eating fast food all day, long check out just look on Amazon or Google search, the hot logic mini for the price. You couldn't beat it okay and they also offer like a little power inverter. If you don't already have one for your vehicle, I'm a little reluctant to leave this device plugged in in my vehicle for two hours, while I'm not in it, because I happen to have a large power inverter for charging batteries and different things. So I could plug it in, but as far as going on the roof and plugging in this device and cooking your food, just let it cook for two hours, while you're working on the roof, and you can actually have a hot lunch.

So I'm no way endorsed or anything by these people. I just thought it was a really cool product and I was really blown away with how well it turned out today. So my thought is: is that I can you know meal prep, a lunch. Have it packaged and then throw it in my ice chest and then you know two hours before it's lunch time, throw it on this little hot pad thing and it's insulated, so it zips up like an insulated.

You know ice chest or whatever and it's super small. So, just when you get an opportunity to look it up, hot logic mini totally worth it. So alright - and I I did I did make like a little video of it today I need to edit it down. I won't release it as a normal video I'll just release it as like a bonus video, so you guys can check it out, maybe tomorrow or something like that.

I don't know if I'll get the chance to do it, but it was just like super quick. I just showed myself throwing some veggies in it and literally just cooking it, and it was like bitching to have a hot lunch. The one thing I will say is again: I'm gon na go off on a rant on this, but when I put the veggies in there, so I cooked broccoli and carrots. I just happen to have a veggie tray because I like to buy veggie trays to snack on them, and I had so.

It already has broccoli like cut up and little baby carrots. So I grabbed a handful of baby carrots. A handful broccoli, maybe like six cloves of garlic, because I really like garlic, I smashed him before I put him in there, the chicken, breast and then a handful of spinach and just put it all in there. When I got all done when the chicken was cooked.

Cuz, the chicken was perfect, it was still moist, it wasn't dried out. The veggies were extremely hot all the way through, but they were so crunchy that you couldn't cut them with a fork, which is how I like my veggies, so they weren't mushy, like you were cooking in the water. You don't add any water to the dish, or at least I didn't so anyways, I'm enough talking about food, but I was just super excited because it's like this, you know I don't have to eat a hamburger for lunch anymore. So that's awesome or some crap.

Yes, fifteen dollar meal. I don't know about you guys, but my lunches have been costing me anywhere from fifteen to twenty dollars a day and it's just ridiculous how expensive that get. So if I can spend you know five bucks on some chicken and some veggies, I'm all for it to save some money - all right. Yes, exactly reefer tech mark better than the drive-thru crap, okay guys.

So, let's uh. Let's try to get to some more of this. Let me know if I missed any other questions, guys throw them in there again, I'm going to try to get to some of those yeah exactly a lot of HVAC guys have had problems. Okay, so Zia has a service call on a walk-in cooler where both condensers were running and both Eve apps would run for 5 seconds and pop the breaker with that.

That sounds like a problem Isaiah so Isaiah. What would pop the breaker, the wok, the evaporator or the condensing unit, where they separated? Was it a hundred and fifteen volt evaporator and then a 208 like three phase or single-phase condensing unit, or was it the same power source? So what breaker was tripping out of curiosity, Jordan, Lee you said: can I recommend a good small HVAC torch set up to weld in small areas? Well, Jordan. I have never used them, but like a B tank is very popular for tight spaces. So that's what it's gon na use, basically an air acetylene tip and all you have to do is drag the acetylene tank up onto the the small little space.

So I've never used one, but they do look. They do look like they'd fit in a tight space as far they do make like micro tips, for your torch sets too, but um. You know it just depends on what you're working on. I myself use an oxy-acetylene rig and I just managed to get it where I need to get it, so I've never used anything other, but I'm always looking for that.

Better torch set because I don't know about you, but I go through torch caddies like crazy and I don't like the metal caddies, but I constantly wear out the plastic caddies. They get worn out so fast, the bottoms bust out and all kinds of things. So I'm always looking for something better but I've yet to find it, and I don't mind spending a couple bucks for a torch, but you know I've just yet to find anything besides. Just your you know thing that you buy from the supply house.

You know just whatever just the little generic torch caddies, okay, the evap would pop the breaker well Isaiah. You need to obviously more than likely you're going to ignore the condensing unit and your problems going to be at the evaporator. Now I will say on walking, evaporators one of the more common places to start is the wiring, as they run from one side of the coil to the other. They'll constantly rub out what I would suggest you do is after you visually inspected for electrical shorts, then I would suggest that you disconnect each evaporator motor then turn the breaker on and see and before you do this, though you want to test for anything to ground, But before you know, if you can't find anything, that's shorted to ground and you can't find any broken wires, then disconnect both evaporator families and turn the power on and see.

If you still trip the breaker that eliminates the evaporator fan motors from the the problem. Potentially, okay, then you can work your way from there and just systematically pay attention to the unit. But what the first place that I would start is is turn everything off and put your meter on tone and go from the end, the neutral to ground, and you know then test each leg to ground to see where the shorts at. If there is a direct short, then work, your way through the evaporator fan motors then disconnect those then work your way through everything else, and you will find the problem just be very careful, alright, okay.

So this question is a fan cycle control needed for a walk-in freezer condenser, meaning is it okay to run without it Julio Mendez? So it really depends on the nd ambient environment. Okay in Southern California, a lot of times we can get away without any kind of head pressure control because our winters are about. You know on the low side, they're 55 degrees. You know.

Sometimes we have extreme lows, but you know for the most part, our winters are 55 degrees and you know we can kind of get away. Should we have a fan cycle control or some kind of head pressure control? Yes, you should anything below 70 degrees. You really should have some kind of head pressure control, but can it operate without it yeah I've seen them operate, just fine without it. You have to understand that the fan cycle, control or the head pressure control valve is there to create or help to maintain the pressure drop across the expansion valve okay.

So as your your liquid saturation temperature drops. Okay, that's the temperature of the refrigerant inside the condenser. As the liquid saturation temperature drops, your head pressure drops okay and the way that, especially with the older expansion valves, but the newer ones that still kind of effects that okay. But we need a set pressure differential between the the liquid side of the expansion valve and the suction side of the expansion valve, so the lower that differential, the more potential for the expansion valve to not act correctly.

Now, I'm probably going talking Chinese in some ways, but with the newer expansion valves they don't have so much of a problem with a lower pressure drop but with the older expansion valves. We definitely had this problem. So that's why we have to have head pressure control, whether it be by a head master valve, whether it be by a fan, cycle control or maybe even like a motor master control for your condenser families. That slows them down.

But yes, the system can operate depending on your ambient without a fan cycle control. Certainly, as long as you don't have like a negative 10 degree, temperature outside you can bypass the control until you can go to replace it for sure. Okay, myself, I prefer a head pressure control valve versus a fan, cycling control, because I feel that fan cycling. Controls are very hard on the system and if you ever work on one in like a mild temperature so about sixty to seventy degrees.

And if you see a fan cycle control turn on and off, you'll notice that they're very rough, like the system will start flashing and it takes a minute to recoup before the sightglass clears up. It can just be very violent on system, so I prefer a head pressure control valve a lot of people, don't like head masters or head pressure, control valves, because you know that people have had problems with them failing so you know to each their own all right. Hopefully I answered your question there: let's go down here: okay, so, okay! So I'm going to answer some of my questions here: okay, that I've gotten so I had a few questions come in from the chat and from emails, and I'm gon na talk a little bit here: okay, so one of the ones that I missed that the last Stream was asking about our SES, my refrigeration service engineers, Society and it's a membership organization that I'm part of they're a training resource for HVAC, our technicians, okay, they were one of the first training resources ever besides the manufacturer. Okay, so someone had asked me if they have to be a member to go to meetings and and or webinars and or seminars? Okay, so you want to consult your local, our SES chapter now my particular chapter, which is the arrowhead chapter in San Bernardino, California.

We do not require people to be members to come to our meetings, meaning that we have a meeting the second Tuesday of every month and anybody can come. You do not have to be a member, I don't care. If you come to every meeting for the next year. I'm not gon na require you to be a member okay.

We are a free training resource. We are a non-profit, we're there to help people we're volunteers. So nobody's getting paid, we just happen just just like I do these live streams, there's a bunch of other guys like myself, much smarter than I and we volunteer our time and we put on training classes. Sometimes we get manufacturers to come in.

Like you know, we've had a gentleman from spoilin come out, we've had people from all over the place. Okay, we had someone from ESCO come out, we had you, know all kinds of people come out and do training classes for us and a lot of times we give those for free now, the second Tuesday of every month. Those are our educational meetings. Okay, those are free, you do not have to be a member, we do have a website, also our SES org, and on that website we do give webinars at this time.

The webinars are not free and you do have to be a member to view the webinars on our website. That is one thing you have to be a member for okay. The second thing is: is that when we have seminars about once or twice a year, we'll have a training seminar where we make a big deal out of it. We put lunch, we usually have one or two training sessions, we'll usually have a trade show and all kinds of stuff those things you do not have to be a member to come to, but usually, if you're, a member we give a discount to members, okay and Then the other thing that membership with RSES gets, you is, is just access to our website on our website.

We have a lot of train resources that are available for free and then we also have even for members, we have some training resources that you do have to pay for, but they're at discounted rates. So so you know to answer the question: you don't have to be a member to come to our educational sessions, but you do have to be a member to attend some of our that's funny. An email just came across my phone so for the RSES meeting coming up next Tuesday, so anyways. So hopefully that answers the question.

I'm gon na look at the chat here, real, quick and see if I miss anything haha prime time likes Headmaster's a lot. I know that pipe says you only have problems with liquid lines are bigger than they are needed to be. Prime time has always had problems with Headmaster's and and again you know some people like them. Some people - don't okay, I will say in all fairness here: in Southern California, we have an extremely mild climate, so the headmaster or head pressure control valve is not bypassing at all times.

You know it's just gon na modulate a little bit here and there. I could only imagine that in colder climates, where I know you're from prime time and especially with poor installation practices, that I'd say almost 90 % of our industry have. I could imagine problems with head pressure, control valves being through the roof. In my opinion - and this is just my opinion - most problems with the head pressure control valve are installer errors, okay or service servicing errors, meaning that people aren't properly evacuating systems.

There's contaminants in the system different things like that valves are overheated when they're installed and again. This is just my opinion and I'm not judging anybody for having a different opinion. Okay, but you know I, I don't see very many head pressure, control valve failures and I don't know mechanically what can really cause them to fail. Besides, you know poor installation practices, but again you know that's just my opinion, so Julio Mendez, a fan, cycling control, Julio.

Thank you very much. Man Julio a fan cycle control needed for a walk-in freezer, meaning is it okay to run with that? Okay, yeah! I got to that one Justin! All right! Let's see here, what did you love, Ted, huh yeah? I think all these fake people - I don't know, Ted, that's funny, why does subcooling go up with dirty outdoor unit or low ambient? That is a good question Matt and I will address that one, but I would actually like you to. I want to make sure that I answer that correctly, so I'm not gon na. I can't rattle that one off the off the top of my head, so I will get back to you on that one Matt and I would highly suggest that you send me an email, okay, my brains not really working right now so HVAC, our videos at gmail.com And I will get back to that one: okay, Matt all right um! Why would a ductless mini-split this is from Jason Arnett? Why would a ductless mini-split have have a pressure sensor on the high side liquid line? Why would it have a a pressure sensor on the high side liquid line? Well, first off: are you sure it's the high side, or is it the liquid line? It just depends on what that ductless mini-split manufacturers trying to do so.

Are we talking about the liquid line yeah? We need, I mean I need some clarification. Are you sure it's the high side line, or are you sure it's the liquid line? I mean because there and I mean essentially they're the same, but I mean I would imagine that it would be a the question that I'm getting at I'm sorry is is, are you sure it's not the the line coming out of the metering device going to the Coil: okay, because that's not a liquid line go into the coil. Usually the expansion valves are in the the condensing unit, so you'll have a you, don't have a true liquid and suction line going to the head on the mini on some of them. So I need some clarification on that one, but okay, so primetime, I'm curious to see what you said here so there's a well.

Canada is a cold place in winter and summer. Our shoes stick to the sidewalks, but I've never gotten away and continue to get away with a headmaster house right on hey if it works for you, it works for you primetime all right, yeah consultive bill burton at bill. Burnett said a great thing: consult the manufacturers. Lord filius, our phil fuss.

Thank you very much for that super chat. I really appreciate it and thank you very much Julio Mendez that made the super chat, really appreciate it, but got questions rolling through here, and I don't want to miss them too much, but yeah. Definitely consult the manufacturer on a ductless mini-split. What's the difference between air conditioning mode and heat pump mode, give me some context there.

Dillon. Are you talking about in a thermostat that you're installing? That's what I think that you're trying to say and the control wiring strategy would be different on a thermostat versus a thermostat for an air conditioner versus a thermostat for a heat pump. Okay, so that I'm assuming that's what you mean on that. But give me some more context: there Dillon, okay, Jason Arnett, you sure it's on the liquid line, okay, yeah! I would lean on the manufacturer on that one, because each one's trying to do something different.

But if it's on the liquid line, I would imagine they're just using it, I mean they could be using it as a high pressure control. I wouldn't think that it would be a great place to put a high pressure switch on a liquid line, but some manufacturers - I'm not super familiar with every mini-split but like. I know that some manufacturers will put a loss of charge, switch on the liquid line. Instead of a low pressure switch on the low side, why they do that? I don't know, but I have seen some package unit manufacturers do that.

So I would say that we probably need to talk to the manufacturer and get their control strategy figured out and what they're trying to do Jason. Okay. So what is the group you said? I am part of our SES. Yes, our SES org, so our SES dot o-r-g is the the website.

You can. Click on that and yeah. Our SES is the organization that I am part of okay. You want to look and see if they have any local chapters in your area, because we have chapters all over place, but some of them are not as active as others.

So alright, hello to everybody, that's coming in here and let's go into here and see what else I could? Okay, it's a top brand! That's why I'm confused about it! Yeah Jason, I'm kind of curious about it too, but so I'd like to do some more research on that. If you'll email me Jason I'd like to know some more context, HVAC our videos at gmail.com, okay, all right! So I'm gon na go to some of my topics here too and then I'll get to some more of your guys's questions. Okay, so someone had asked me a question: they're, a new tech in HVAC and they're, going to trade school right now, and they want to better themselves, I'm paraphrasing this question. He wants to better himself and he wants to know if I have any things that I know of any new emerging technologies that trade schools are not covering yet so that way he can better himself and one-up the next guy in school with him.

Does that make sense? So as far as things that trade schools aren't going to cover, it really depends okay, because each trade school is different. What I would highly suggest is you subscribe to the email newsletters that Brian or puts out HVAC our school comm, okay, and he has a newsletter and he is constantly putting out articles written by people. Like myself, I mean it's been a while, since I've written an article for him, but I've written articles, he has lots of other really smart dudes much smarter than I that write articles for him too, and they're constantly writing about new technologies and new things coming out. One thing I will definitely say that trade schools, most trade schools, but I can't group them all into one big group because everyone's different, but I would say, majority the trade schools that I've heard from and talked to are not doing very much with vrf systems or Vrv systems - okay, in that variable refrigerant flow.

You know, there's all kinds of fancy brands out there and that is definitely becoming a very, very popular type of HVAC system in you know high-rises and schools and commercial buildings. Because of how you can you know, reduce the capacity you can slow down, compressors they're supposed to be very efficient okay, so I would suggest that you do some reading on that. As far as where to get the best train, you're gon na have to go to each individual manufacturer. Okay, so there's not like one particular way that someone can teach you how a VR BRF system works right, because while they all share the same concepts of refrigeration - and you know they just basic refrigeration concepts - they all have a little bit of a different strategy.

Okay, so daikons a little bit different than Mitsubishi city, so they all kind of have their own little niche and way that they work. So you want to lean on each manufacturer. So I highly suggest that you do some research on VR v and v RF systems. That would definitely be a way that you can better yourself.

The next thing I would do is definitely research. Some of the new you know apps and different things that are coming out for phones, some of the new control strategies that I don't know where I want with control strategy that I mean to say that, but like some of the new apps and different digital technologies, That we have available at our fingertips because they can also help you out too again. You know, if you would email me, I can kind of give you a little more context and we can talk about what your your particular trade school is covering Dmitry. Thank you very much, but I really appreciate it what your particular trade school is covering, because it's that's kind of a vague question.

You know so so send me an email at HVAC, our videos at gmail.com, and give me some more context about your question. Let's go to okay. This is another good one too, for the guys that are in commercial refrigeration. You probably already know this, but Johnson Controls and Orpen makes a thermostat.

It's just a universal thermostat. It's the a 19 series thermostat. This is not the digital one. It's just a mechanical thermostat and someone had asked me why they never read accurately okay and what I mean is is sometimes you have to set the thermostat at 30 degrees to maintain 38 degrees in the box.

Okay, number one: it's because it's a mechanical, thermostat, okay Digital, is going to be more accurate when the sensors are working properly. It is very common knowledge to know that if you're working with the Johnson control stat, I say stat short for thermostat - that you you understand that the the numbers is far on the dial or more or less a reference point and that you're gon na you're gon Na adjust it, you know and and watch the Box turn on and turn off. Okay, another thing with the Johnson Controls mechanical stats is you have to absolutely 100 %, make sure that they're mounted on a level surface, meaning that if you're mounting it in a walking, coil right and the walking coil has the seams where the walls meet. If one is sticking out, you know an eighth of an inch further than the other and that's a very common thing in a walkin, as the walls never meet up perfectly.

And if you try to screw one side of that thermostat to one of those walls and the other side to the other wall like right on the seam, it'll bow the inside of the thermostat and it won't work properly either. So that's a very excuse me. Very, very important thing you know: what's funny is again knowing that my problem is still going on at work, as I'm talking to you guys. My stress level has dropped tremendously so like it's like I'm able to once I'm able to start talking, I'm able to kind of push that aside.

I don't have to deal with it when we get off the stream, but it does help me therapeutically to talk to you guys so cool thanks guys for listening. Alright, let's go to some of these topics. Okay, let's see! What's here, you know what a superior! I don't know the context of that. You said why, don't you just be distributor free country like Ted's state and buy a good brand direct.

I don't know the context of that statement, but it's funny that you say that because I was just thinking today that I i hate government regulation. I really do and I think that we're over regulated, but I don't want to get all political, but the one thing I do wish was that our government would get involved and let these manufacturers know that they can't be selling their products directly to customers, because that Drives me freaking through the roof. I think that and you're making me go off on a rant just because I saw one thing in your phrase, but I don't think that manufacturers should be able to sell direct to consumers, and I think that they should have to go through distributors and keep us People employed anyways going off on a tangent there. So all right, the Johnson Controls stats into a pressure, switch Arpita, yeah, reefer tech mark um.

You know i like their pressure controls johnson control pressure. Controls are my favorite, but mark you work in transport refrigeration. So i could imagine that i was thinking about after i saw your email, the transport refrigeration people, you guys must go through a lot of controls because of the vibration, and that must just drive you guys, nuts, you must change pressure, controls, left and right and contactors And different things all the time - and I mean yeah I could just only imagine, are they using scroll compressors in the transport units, yet are they still using semi hermetics again, I could just imagine the vibration just wreaks havoc on everything you must have so many refrigerant Leaks: okay, okay, Jason Arnett you're, going to a mini-split class at AC pro and Anaheim on May 21st. If anybody is interested, that's good to know Jason yeah, we have - I I don't use AC Pro very much, but I do do a little bit of work with them or I'll pick up some cheap metal and stuff from them every once in a blue moon.

Okay, so what's my thoughts on some residential YouTube, HVAC texts that show everything on their videos like how to check parts and other stuff: do you think that parts the issue resides text making yeah the teto 209? That is a good question, so I can't really I'm not gon na judge anybody for the way that they make a YouTube video, but you bring up a really good topic that I wanted to cover too and I'll get to that. But I'm gon na talk about. In my opinion, we shouldn't be showing everything on a video. Okay.

If you guys already see my videos, my videos are made for technicians. My videos are not made for business owners they're made for people that understand what they're doing. I'm not gon na show you how to set up your your oxy-acetylene torches, okay, because that's not my business to teach you that it's a huge liability on my part, I'm also not going to show you from you know from start to finish on my jobs. Okay, I'm gon na show you the problem.

I'm gon na show you a few interesting things in the middle and I'm gon na show you the conclusion. That's just the way that I roll with my videos. Okay, I don't want to judge anybody for what they do, but you that's just not how I want to do it. I don't want to show people the entire job, because I don't want to take the food out of anybody's mouth right.

Other service techs or anything like that. I want my videos to help service, techs and business owners, and you know I think that it's it's good also. If restaurant owners are watching my videos, because maybe they can see what their service techs have to go through, like I'm, okay with that, but I just don't think that I'm. I just know that I won't show from step one to step ten through them through my videos.

That's just not how I'm on a roll! On another note, I want to bring to your guys's attention that there has been and again I don't want to sound cocky and I don't want to sound rude. I am a humble person, meaning that I know that there's much better Tech's out there than I okay and there's a lot better. There's there's several texts that I wish would start making videos of their own lots of Supermarket text. You know that I would love to see some more videos from, but there's also an influx right now of people that think they can just make a video and guys they're showing really bad information.

Again, I'm not perfect. I make mistakes. Okay - and I will always own up to a mistake, if you guys see me, do something wrong in my video. I would appreciate, if you guys, reach out to me, you know someone caught a mistake that I made in one of my videos where I installed the wrong size nozzle on an expansion valve for an evaporator, coil, okay, I I watched the video myself holy.

You know what I made that mistake. That was my bad and I owned up to it, but I don't like to show false information and there's some new service texts right now coming out and oh my gosh. The information that they're sharing on their videos is horrible. They're sharing it in groups, there was one guy on HVAC hub, which is a Facebook group today that shared an expansion valve video how to adjust an expansion valve, and it was completely wrong.

He was ignoring all kinds of problems, a VR 1961. Thank you. So very much dude there was, you know, there's there's so many guys out there right now that are sharing wrong. I shouldn't say so many, but there's a lot of new texts that are starting to make videos.

So if you are going to make videos just do a little research to make sure that you're a hundred correct and again I you know - you don't have to be flawless because I make mistakes too, and so do the other guys that are making videos. But I don't know you guys just need to be careful when you're watching some of these YouTube channels, because there's some man - oh my gosh yeah, I I was. I had this big ol comment, typed down on someone's video today, but then I decided to delete it because I just don't want to start drama, even though there was a bunch of other people already saying the same thing that I wanted to say. But I just don't like to get involved in drama, but just be careful, be careful, you new guys that are listening to some of these people out there, because it's not necessarily correct okay, that the best way that you can, I mean, there's ways that you can Watch a video and you can understand if someone kind of knows what they're talking about, but I would highly suggest that you look at the comments.

Look at the comments over and over and over again on their videos. You know most of the time people will start chiming in on the video saying this is absolutely wrong. This is, and then that kind of gives you some context. Okay, so just pay attention to the comments, because there can be some really bad information out there too, and I would I would hate for one of you guys to watch one of these videos and try to follow what this particular tech today was doing, because it Was horrible so alright try to get to some of these questions and, let's see okay, I see some conversations going on, so I don't want to get to okay, so hey Zeus, Hernandez says: can I explain how to use a valve core removal tool? Avr 1961.

It's sent $ 25. Is that what you meant to send, or did you mean to send $ 2, because I can adjust that I think so? Let me know if that was incorrect dude I know sometimes that can be kind of confusing okay. So could I explain how to use a valve core removal tool guys if I'm missing your questions, type them again put them in caps, lock? Okay, so that way we don't miss them. You keep typing them if I skip over them.

Okay, so a valve core removal tool so understand that a valve core is in the system so that we can add refrigerant right and be able to take our service gauges off and we don't lose all the refrigerant right. So the valve core resets and stops the refrigerant flow out of the system. You usually just get the slightest little. You know, okay, if you're you're, depressed and everything is working correctly.

Let me I'm getting distracted here. Okay, oh I don't know, I don't know what that scent. Avr 1961 I'll have to look and see dude, I don't know if it's sent to or 25 off, I could have been confused. Sorry, so a valve core removal tool, the valve core removal tool, is essentially there to take the valve core out.

While the system is pressurized. Why would we need to do that? Well, number, one: what happens if we have a refrigerant leak on that valve core? It's a very common thing: the valve core might not set right and it just leaks refrigerant out. Okay, we want to be able to change that valve core without having to remove the entire charge. Okay, so the valve core removal tool usually has a set of ball valves inside of it and when you screw it on to the quarter inch fitting.

It has a little chingus inside of it that pushes in there and grabs ahold of the valve core and unscrews. It while the system still stays sealed, okay and so you're, not leaving losing any refrigerant. Then what you do is once you unscrew the core: it pushes into a little stem and then you close, the ball valve. You remove the stem and your core should be in there.

I'm gon na give you guys a little tech tip for some reason. If you can't get the valve core out, sometimes they might get stuck in the core tool. That's a very common thing I run into especially once the core tools get kind of old AVR there you go dude. Thank you! So very much man, you guys with these super chats, like I'm super blown away Clint.

Thank you very much, okay. So, on the the so a little tech tip for the valve core removal tools, number one if the valve core won't come out like if you can feel it because if you know how valve core tool works right at my nose start a niche, I see you In here Zack you're causing it if the valve core tool won't grab a holder, won't loosen, you can feel that it's loose, but it just won't come out with the stem. What you can do is put a second valve core tool on top of the first one ball valve it off. Take the stem out, put a second one on there and then open the second one and it'll blow the valve court.

I'm sorry open the first one it'll blow the valve core into the second one. If that doesn't work, I've never done this, but I've heard of another service technician if you're a hundred percent sure that the valve core is loose, but it just won't come out. I've heard another guy telling me what did one time was. He just took the stem off and then opened the valve core ball valve and it blew the Schrader across the room again.

I would never do that because that violates EPA protocol and I don't know if that would be considered de minimis loss, but I have heard of someone doing that, so you know interesting thought there guys the super chats are amazing. Thank you so very much. Okay. I appreciate that superior.

Hopefully, hopefully you guys think my stuff is legitimate. I try to be so. Oh good, one good one delicious sniper. I think that's how you say your name.

It says why does old equipment last so much longer than newer stuff? Okay, but because the new stuff, the profit margins, everybody needs to make more and more money and the Amazon effect. Okay, right, Amazon came out and it drove everybody's prices so so so low that they couldn't make money anymore. So they started making cheaper and cheaper products. Okay, that's not just Amazon that did that it's all the big-box retailers everybody's always done that, but that the you know urban dictionaries coined that phrase, the Amazon effect.

We demand lower prices. Therefore, the manufacturers have to deliver. You know a product that still works at lower prices and the only way they can do that they can't take away from their profits, so they buy cheaper materials. All right, thinner, copper, different things like that, so it is a hundred percent.

True that I can remove a unit from the 1980s right now that has lasted all the way to 2019 and the new unit, even if I bought the most expensive refrigeration condensing unit and put in installed it, it's not gon na last half as long, you can't Buy the quality that you used to be able to buy it. Just just won't work. Okay, we drive our wages up. Did you know that in Southern California, we're on par to put minimum wage at $ 15 an hour minimum wage $ 15 an hour? Don't get me wrong, I believe everybody should make more of the most money possible right, but minimum wage at $ 15 an hour.

What do you think's gon na happen to all the restaurants, all the right? What do you think's gon na happen at Walmart? That's what the managers were making at Walmart? Okay, I don't want to go all political, so I need to be careful about this, but we are doing this to ourselves. We are demanding crappier equipment because we want it jeepers. So it's us that's doing it. Okay! Is it legal to buy parts from a warehouse without a contractor's license some refused to sell to me I have schooling, EPA cert and work maintenance for over five years, just for my unit, just Russ whether or not I agree on whether or not you should be Able to buy parts, it is not illegal for a supply house to sell you a part.

However, there's some things that can be problematic. If you have your EPA license, they you know you're fine, but if you didn't have your EPA license, they couldn't sell you some refrigerants, but you know. Are they a wholesale house if they're a wholesale house, you know they would have to tax you on that right because most of the wholesale houses that I go to they're selling me the equipment at non-taxable rates? Basically, okay, so is it illegal? No, it's not illegal, but that's just the way that they say it to say. You know to basically get away from being able to sell to you.

There is some manufacturers out there, some supply houses that sell to the public, I'm not a fan of it. I'm not going to name them, but they are out there. So you know you got to do what you got to do, but I would think that if you're in building maintenance, you should have a decent supply house that would sell to you. You shouldn't, you should know someone talk to a manager and tell them it's for your mom or whatever and they'll usually hook you up with something okay and that that's in the United States.

I don't know about other countries, so be cautious about that. Okay, Dylan, my and says question was: is there anything different in the compressor? Does it operate backwards? It confuses me because air conditioning and heat mode does basically the same thing: I'm not a HVAC tech. No, there is not a difference between a heat pump compressor and an air conditioning compressor. Okay, only make sure here now no compress is a compressor.

What changes the unit from a heat pump to an air conditioner is a reversing valve. So, but you know, depending on different models of units. Yes, there could be different parts depending on different tonnage. -- is yes, there could be different model number.

You know different compressors, but in general, there's not really any difference between a heat pump, compressor and an air conditioner pressor. Okay, you know different models, you know, can run it's not going to run backwards but like if you have a three-phase compressor and you install it incorrectly, it can run backwards. But again, I need some more context to your question there, but okay, okay, so the Tito 2:09. What's your thoughts about on call like overwork overworking a tech, for example, the most I worked was twenty six hours straight yeah.

I've never worked 26 hours straight. I'm trying to think I think no wait. I've worked more than oh, no, no, not 26. No! I've not worked 26 hours.

I think I've worked like 20 to 23 hours in a day. Hell yeah overworked me, but I'm the owner. So I can do that. You know there's a point at which you have to draw the line.

Okay, you know that's where I can't expect my text to work like that when we have crazy, crazy busy heat waves and different things like that and we're super busy I'll bring it up to my text and I'm not gon na be pissed off. If they can't do another call okay yeah, I have more calls I need to get to, but once we get past a point you know once they get past like 10 hours overtime, you know or something like that or eight hours overtime. You know whatever.
