Ah, it's time to chill out and get ready for a mediocre q, a live stream if you're old enough grab yourself your favorite adult beverage and if you're not stick with apple juice, put your feet up and relax. If you have any questions, feel free to ask them in the chat and now, let's queue up the intro music got ta wait got ta, wait there we go now. It's over had to wait till the little outro music completely finished. With that last guitar slide down the fret, you know: how are you guys doing this evening? I have to say that i've probably heard that song a ridiculous amount of times when i think about how many live streams.

I've been using that music. For you know, i've been doing these. Let's see, i started my channel. My channel alone in november of 2017 is when i started my channel and the live streams i think started by like june of 2018 and i've been doing them pretty consistently every monday.

If i had to guess, i might have missed, maybe less than 10 live streams is, is what i've missed so try to stay consistent as possible, which is also pretty crazy, because i can't stay consistent on anything else. In my life, um, everything always gets thrown off because of work or whatever, but it's kind of crazy, but yeah that same intro music. I don't know i still like it. I still dig it and actually, when i found the second intro song, which is the first one that i play now, i like the the first one so much and now i'm getting really confusing, but i like them both so much that i play them both so And the whole, you know i get people asking like.

Why do i why the intro music? Why the headphones - and i know you're just joking but still um, the headphones is so i can hear myself because when you're talking into a microphone and actually at first it's kind of overwhelming hearing yourself, but then you get used to it when you're talking and it It helps you to hear your levels and, like i can hear what you guys are hearing. So if i get too close to the mic like i can hear that - and i i can remind myself: hey stay away from the mic, that kind of stuff or eat the mic or do whatever you got to do so. The headphones are really just. You know an excuse for me to listen to myself.

Talk is really what they're for and as if you guys, clearly see the videos. You know that i like to listen to myself talk so um. Ironically, you know one of the questions that i get majority of the time yeah you know, how can i, how can i charge my customers to film these service calls? Am i doing them an injustice that kind of stuff and actually no because i've said this a bunch of times, but the way that i troubleshoot is to talk to myself and rationalize with myself, i'm a i'm a vocal person. So, even when i'm by myself, i'm talking to myself answering questions okay, what about this? And what about that um? So exactly what you guys hear in the video is typically how i talk.

Even if i'm not filming a video so um, i definitely have some mental issues um and while i'm talking about that well before i get into that, let's, let's start this thing off right, so hello, everybody! I hope you guys are doing well um, i'm alive it's another day. I woke up this morning, so i guess that's a good thing. Sometimes i question that, but you know i guess it's another good day we are doing well over here. The weather is cooling down a little bit, but you know it never gets really cold here in california, but today i think it was maybe 85 degrees outside all day and then tonight, it'll, probably drop down into the low 60s is, is what it'll drop down into And then we'll have that off and on until about november-ish, then we'll have the santa ana winds, which is an annual wind event that we get in the southern california region and then after the santa ana winds.

That's when our cold season right cold season, because we don't know what cold is but that's when everybody gets out the ugg boots and the beanies and and zip up hoodies. You know because that's all we need for our cold weather here, um but yeah. We don't have real winters here and then we'll have a somewhat cold season until february-ish and then it'll start gradually. Warming up into the 80s and by the end of april, it'll start hitting the 90s and then so forth and make its way through so but uh yeah, i'm doing well, and for those of you guys that are new here uh, i don't know why.

I do this, but for whatever reason i feel the need to do so. My name is chris and i'm an hvacr service technician here in southern california and uh. If you're completely new to the channel, i make these videos. Maybe you haven't seen my videos.

I don't know, but i make these videos on youtube as a training aid for my employees and i, after some reluctance and some time i decided to make them public, and here we are now a couple years later yeah. I do these live streams to answer questions and kind of help. Myself stay sane because i get so many emails comments messages all that stuff and i find myself staring at my phone 24 7 or i found myself staring at my phone 24 7.. So i started doing the live streams to consolidate the questions and answer them in a live format, so that i didn't have to type responses to the same questions 20 times.

I literally get the same questions over and over and over again, so um yeah. That's the whole point of doing these things, so definitely a lot of things i want to talk about for those that are in the chat on youtube. Do me a favor if you guys have questions or things you want me to cover. Put your your question or your comment in caps: lock all capital letters that helps me to see it and remember that there's a lot of people in here and they'll continue to file in and they'll continue to ask questions.

So if i don't see your question it scrolls by um, it makes for bad internet, i guess or bad whatever. You want to call it uh. If i sit there and scroll through the comments a bunch of times, so just keep reposting it until myself or one of the moderators tells you to stop. If i completely miss your question tonight feel free to send me an email to hvacr videos, gmail.com and i'll.

Try to respond to it in there, okay! So, let's get on with this um. I want to talk about, and i was kind of joking around in the beginning that i'm a little bit crazy in the head and - and i know that i have issues okay, but don't we all right? I really think that we do, and i feel like the word normal - doesn't really make sense. Okay, because what is normal? Is it normal to have um minor mental issues to have anxiety to have depression? Is it normal to not have any of those things, or is it normal to have all of those things and hide them and pretend like you, don't what is normal? Why do we even use that word? I feel like the 98 deville. Thank you so very much for that super chat bud.

That's amazing! I really appreciate it uh. He said to smash the thumbs up button, so please do guys. It'll definitely help out the stream, but when it comes to anxiety, depression, all that good stuff, okay, guys, we all deal with it and i feel like a lot - and i could be wrong in this. But i feel like a lot of people.

There's like a stigma associated with it, and nobody wants to admit it. I feel like in in my heart. More people have these issues than not, and we need to talk about it. We need to communicate.

We need to normalize this stuff because we all deal with it. Okay, you guys may see it in my videos. I may express frustration or anger or whatever. Sometimes i don't.

Sometimes i express it to my friends to my family, to my wife. It's important that we communicate i'm not perfect. I've realized and i've seen or seeked seeked. I don't know if that's the right word, but i've gone and got help i've.

I've spoken to therapists and psychiatrists and and dealt with issues. Okay, and what i've come to terms with for me is that i'm gon na deal with those issues for the rest of my life, but i've just learned better ways to cope with them. That's what works for me, that's how i've learned how to deal with it. So i just want to talk about this.

I know it seems silly that i talk about this more and more, but i think more people need to talk about this stuff. Okay, because this is things that we all deal with all right, we need to, or i feel like you know, i would hope that we can all start sharing this stuff more and more um. That way, you know people don't feel isolated and scared and upset and feel like they're all alone i mean we all deal with stuff, guys all right, um, so uh, look at that jason johnson says: is it normal to want to strangle most of humanity? Oh no! Okay, yeah um, you know if i'm gon na tell you guys a story. I don't know if i've told this story before but um.

I am the type of person that wears on my face. Okay, i just do um. I i have that look on my face. So my my daughters and i were at this - was uh - maybe a year or two ago - maybe two three years ago, to be honest with you, but we were sitting.

My wife was out of town and my daughters and i had gone to a local plaza here. In riverside called uh riverside central plaza and it just couple restaurants and different things, and we were sitting outside and there was a lady going around um. She was clearly you know something was going on. She might have been homeless, who knows, but she was walking around trying to sell candy bars, mind you.

It was like 100 degrees outside and she's trying to sell chocolate bars that are probably all melted but she's walking around to everybody and when it came time for her to come to the table, where my daughter and i were sitting, you know she walks right past Us moved on to the next table and both of my daughters looked at me, perplexed and my oldest daughter said dad. Why did she walk right by us and not try to sell us that candy bar she went to every other table and i said because i have written on my forehead. I wear it on my face and people know for the most part. They don't approach me.

Okay, because i just have that look um, it's a blessing and a curse at times right because i'll get a i'll be in a supply house and there'll. Be someone looking at me i'll just notice, like hey, someone's looking at me and then later on i'll, get an email, hey man. I saw you in a supply house, but you looked busy. I didn't want to bother you, you know, and then it's like i'll have to email them back.

You know what i get focused and i get just in the zone when i'm doing things. So you know, if you guys ever see me out in public, stop me and say: hey, you know um, you know just just say. What's up, sometimes i don't pay attention to what's going around me and i'm just you know just mind focused on whatever i'm dealing with or whatever. So i just have that about me.

Um, let's see, let me see what else we got going on. I'm gon na look in the chat, real, quick and then i'll get to my list so um, let's see, could an expansion valve be installed in an upside down orientation? Uh yeah i've seen expansion valves installed in an upside down orientation. The problem that i will see, depending on the manufacturer, different manufacturers have different mounting requirements that you want you to do with different valves uh. The one thing i will say that i've noticed can be a problem is when an expansion valve has been installed upside down.

I've seen it very regular. The oil will start to accumulate in the power head like right where the power head screws to the valve um. I've never really found a problem with that. But when you go to take a power head off, you'll just sit there and have to drain oil out of that thing.

It'll just kind of you know just pour out for a minute, but it just depends on each manufacturer. They have different ways that they want. You to mount certain valves same thing with like solenoid valves and different ones, depending on the type of solenoid valve or type of expansion valve. They may require you to mount it in a certain direction, but uh interesting.

It says that youtube is experiencing buffering. Oh, i don't know, i don't know, what's going on it's working on my end, so let's hope this thing's working all right, um, uh ike! Thank you. So very much for uh continuing to be a supporter and ike's, pointing out that i do have a discord. Server.

Um, i got to be fair and honest that i'm not in that discord server in a very very long time, but there is a discord: server um, it's the hvacr videos, discord, server and uh. It's just a place for people to hang out and talk um. If you guys, i i don't, i'm really bad at having this stuff. So if you guys are interested in the discord, server shoot me over an email to hvacr videos, gmail.com and i'll share.

You guys the link and all that good stuff. Okay, all right, let me see what else we got going on in here: um, okay, i'm gon na go and get to my list of things to talk about so uh. I was scrolling through facebook before the stream just kind of looking at all the comments and emails and different things like that, trying to figure out what was going on um and uh um, oh interesting, chris anderson, so it did buffer huh. I don't know.

I have no idea what's going on, but anyways um i uh was scrolling through facebook and there's an ice machine group. It's called ice machine, peer-to-peer, uh group and uh. It's you know. Just people talk about ice machine, related questions and stuff, and i was in there and i noticed a question that i thought was uh worth talking about on the stream, so um the it was more of a comment saying you know um.

Why do the locations? And let's give you some context, it was a fullet ice machine. It was off on a clogged drain safety and there was clearly with the picture shown. There was clearly a bunch of calcium, um uh, showing up and uh i'm not going to share the guy's. Last name, but it was a a facebook person that i communicate with regularly named roger that had posted this so um.

It was talking about calcium buildup in the machines, and the question was: why do locations think that maintenance is robbery, alluding to the fact that restaurants or locations that have ice machines sometimes don't want to do preventative maintenance, because they might think that it's a ripoff or Something like that, it's we're we're guessing on why they don't do it right, because we really don't know, but i'm gon na say that a lot of the blame when it comes to preventative maintenance and the lack of preventative maintenance on ice machines. I want to push back on the manufacturers of said ice machines majority of these times, i feel, like the manufacturers are not doing a good job, representing the way that their machines need to be maintained, uh having a machine given to a customer and then um, because A lot of these customers buy these machines themselves. Okay, if you're dealing with national chains and big people like that majority of them are buying the machines direct from the manufacturer, uh, the the contractors for the most part when you're dealing with restaurants and things unless it's small, mom and pop restaurants, the contractors typically don't Have a lot of say and or don't get the opportunity to um what the heck is going on here. Did my stream i'm getting like weird messages? Oh that's, weird.

I'm getting weird messages from my streaming software, but um the manufacturers. Don't do a good job of relaying to the consumer, the amount of preventative maintenance that needs to be done and or there's certain manufacturers that share information and advertise that their machines are so easy to clean the end user can do it themselves and they don't share Truthful information about how long it takes to properly clean these machines. Okay, so i feel like they're all trying to sell their machine and their marketing materials are saying. Ours are the easiest machines to clean.

You know it's all marketing pr information and it's not information. That's very true, in my opinion, because to properly clean an ice machine takes hours upon hours to strip the entire machine down, pour the cleaners in it. They all say: oh yeah just put cleaner in push the clean button and move on. It's not that simple.

You need to break these things down. You don't necessarily need to do that every month, but depending on which manufacturer you do have to do it. So i feel, like the manufacturers, are not doing a good service in how they market their machines. Now, if the contractor's selling the machines, then sure you know they need to do a better job too, of letting the consumer know that this machine has to be cleaned.

You know this often or water filters need to be installed or insert whatever. Here. One of the questions that i see often on social media too, and i'm going to say that i'm guilty of this too, is you know when it comes time to sell water filtration for ice machines. You know it's not a one-stop shop when it comes to water.

Filtration every different city, every different county might have different water quality and it's not really just a one-stop shop when it comes to water filters. But the manufacturers again are to blame for this, because almost every ice machine manufacturer out there sells their own brand of ice machine water filter and then they say, yeah just sell this filter and it'll keep the water clean. Well, it doesn't necessarily mean it's going to keep it clean for the area. You're going into different areas require different filtration.

So again, i feel like it falls back on the manufacturer for not educating people and letting them know. Now, when i said that i'm guilty of that too, i am okay, because you know you sell an ice machine and then you buy, you know you're selling, a hoshizaki ice machine, you buy a hoshizaki triple water, filtration system, and you tell the customer they're good to Go when that's not necessarily true, okay, the real way to do it, and hardly anybody ever does this anymore. But the real way to do it is to take a water test, send it out for testing and find out what's in the water and what you need to do to remove said minerals, chemicals, whatever it is in the water from the water. Another interesting point of discussion - and this is very interesting on some older ice machines, especially on some of the older manitowoc ice machines that had water level or water, sensing probes that actually touched the water right, water level, sensing probes and ice thickness probes on the old Ones that actually touch the water and touch the ice and that's how it would terminate you can actually clean the water too much, because if you remove too many impurities from the water uh, it doesn't have conductivity anymore and it wouldn't work right.

So that was a whole nother thing uh, you know, there's there's actually the possibility of cleaning the water too much, but that's on the older machines not really on the newer ones. They've addressed it and fixed a lot of things with them, but you know there's all kinds of interesting factoids when it comes to what we do and it takes research and listening and and talking with manufacturers and hearing horror stories and learning and being like. Oh yeah. Maybe i shouldn't do that or you know this is why we need to do that so interesting, um all right.

So, let's see what we got. I'm gon na look at the chat, real, quick and uh. Let's see um you're sitting here next to your wife. Watching me, can i please say ezzy what it do, baby, what the hell ezzy, what to do.

Baby boo, that's weird! All right! Uh! Let's see we hear me, everything is good. Oh okay, right on all right yeah! So i'm looking in here do i prefer certain type of filtration systems. Uh. You know, it really depends.

I mean when you say, do i prefer a certain type of water, filtration system uh. You know there's the easiest ones which is like ever pure style or, and they private label them too, for hoshizaki scotsman, all the different ones, but it's literally just um an ever pure style cartridge, and it's super easy because it just twists in and the cool thing About the ever pure style cartridges, if it fits your water quality, whenever the water filter plugs up, you know because oftentimes the customers don't replace them on a regular basis and you'll get a service call and the water filter will be plugged solid. It's really easy to bypass an ever pure filter. You just pull out one of the o-rings on the top there's, usually two o-rings pull out one of the o-rings and it'll bypass the filter.

It's super easy, but yeah i mean you know it's all about. What's convenient and easy, but really it depends on what you're comfortable with and what you use you know regularly. So all right, let's see what else we got in here: um can a fan cycle control, cause premature equipment, failure by them being violent on the system. Um you're referencing my dislike for fan cycle controls because they are violent on the system, uh, meaning that when they bypass in you know mild climates like i have because i'm in southern california, so we don't really get super cold.

So when a fan cycle control will turn off the condenser fan motor because the system pressure gets below it'll only be off for like two three seconds, then the fan motor will turn right back on because it's mild weather outside it's not super cold. So you know when it turns off the pressures rise really fast, then it turns on and then they go off and then it go on and it's just like a vicious cycle. So the fan motors seeing high in rush every single time could it cause premature system failures. It's hard to say i mean it doesn't seem like it's very good on the motor, but i mean to be honest with you: there's a lot of systems out there and they run just fine, so um, i'm gon na pass the buck on that one and not.

I mean i don't like it, but is it really really that bad? I don't i don't like it. That's that's pretty much as much as i have to say about that. So could a variable speed fan work in place of a headmaster to control head pressure. Cyborg sheep: yes, there's a very, very good solution to head pressure, control valves.

You could do that, but turning off a condenser fan motor sometimes is not enough. Sometimes you do have to flood the condenser, so in really cold ambience like if you go to minnesota michigan up in the north new york's up in the really really cold areas you might have to have fan cycling and head pressure control valves. So you know simply just slowing down a condenser fan motor might not work in a really cold ambient. Now in southern california, where we have mild winters, yeah that'd be a great solution, but then you have another issue to put a variable: speed fan into the system.

Most of the time i mean you can do like a cheap solution where you just put like a motor master in there, which is essentially going to slow down a motor using kind of a rheostat kind of a device. Not the greatest. And you have to be careful what type of motor you put on it, whether it's a ball bearing or another type? If you go to a true variable, speed motor, maybe like an ecm or possibly a vfd driven condenser fan motor, then you have extra components added to the system, and here we speak on the west coast and southern california. Specifically, we have a horrible power grid where we have a lot of brownouts and things like that and most buildings and locations don't have proper power conditioning.

So you lose circuit boards on vfds and different things like that. Quite often so, i'm still a fan of old school going with the head pressure control valve when it comes to capacity control. You know: what's the reason for a head pressure control valve, it's used in refrigeration and air conditioning systems; typically that have expansion valves and have receivers. Okay, you're not going to see this on a standard air conditioning system and let's some weird engineered system they're there to maintain a certain pressure differential across the expansion valve.

Okay, the expansion valve is a metering device, especially on the older thermostatic expansion valves. Think about it. This way the expansion valve meters, the refrigerant i've, used this analogy before, but if you guys stand outside with your thumb on a water hose, the water will fan out. But as you turn, the water pressure down the water doesn't go as far the water doesn't fan out as far okay, because the pressure's been reduced.

As you increase the pressure, the water is going to fan out and shoot farther okay, so an expansion valve is meant to um control, the flow of refrigerant at a certain rate. So that way you can have evaporation that occurs inside your evaporator. If that flow rate, if the refrigerant is not moving at a certain velocity, then the expansion valve can only control so much so you have to maintain the pressure differential or maintain the proper pressure on the liquid line coming in. So that way, the expansion valve can meter the refrigerant properly okay.

So that's why we use a head pressure, control valve or slow down, or you know, condenser fan motors or shut them off to try to maintain a pressure. Differential people are going to be running into those a lot more as the weather's cooling down, and on top of that i've talked about this a little bit, but i think it's really important that we talk about this too. Any new, larger condensing units are going to be awef compliant refrigeration, condensing units awef uh annual walk-in efficiency factors is is like a government federal regulation that walking coolers bigger than i think it's. I don't remember the number but walking coolers bigger, walk-in coolers have to meet certain energy efficiency requirements, okay or actually um.

I believe it's on all walk-in coolers up to a certain size, so they have to meet certain energy efficiency requirements and so they're doing that by changing the condensing units, making them operate at lower uh current draws and reducing the head pressure, control valve bypass pressures and Increasing the size of the condenser, so with that being said, if you go and try to take a brand new condensing unit, that's an awef compliant condensing unit and throw it on an existing system because sometimes we'll just do a condensed unit swap you need to make Sure that your expansion valve is sized appropriately because oftentimes they're floating the head pressure down a lot lower. So some of the head pressure control valves don't bypass until 100, psi or 150 psi and that's for standard condensing units that might have 404. Or you know some of these other newer refrigerants in it. So with that being said, if you're trying to use an existing expansion valve, you might run into problems.

So that's just something to keep an eye on when you're, swapping out condensed units and not changing everything else. As these new regulations come out, essentially think about it as um, you know, like the seer rating requirements, that um uh air conditioning like residential air conditioning systems. Have i don't know what it is, what is it like? 14 seers the minimum requirement now or 13 seer or something across the united states. I think that's what it is here in california, they're kind of going the same route with refrigeration equipment too they're trying to increase efficiency.

You know and do that kind of stuff. So with that comes some other complications that we need to concern ourselves with. You know all right, so um, let me see uh. You know in my recent video when i had the train package unit um and i think i kind of covered it in the video too, but i'm just gon na own up to it here too um.

You know i was using an insulation, tester or a mega ohm meter. I was using a fluke 1587 and uh using an insulation. Tester is new to me. You know and i'm not afraid to show my ignorance um, i'm still kind of learning with them.

I've kind of pulled away for you know kind of avoided using an insulation tester for many years, but i kind of decided. You know what it's something i should probably show a few times in the video. So i picked one up and i used it in the video and you know some of the things that i said, weren't entirely correct, while nothing that i did was completely incorrect. You know just some of the ways that i explained certain things wasn't quite 100, accurate um in some of the references that i use.

But you know i i'm a normal person, i'm you know. I've never said that i'm the greatest and best of anything, i'm just a guy that tries to be as honest as possible and show my mistakes, and so i try to own up to the stuff as much as possible. Again, i'm learning a bunch of people reached out to me sent me all kinds of cool documents, told me things that i knew told me things that i didn't know so i feel like you know. We all have things to learn and it continues every single day and nobody is the best and greatest at anything.

Everybody is still learning in one way or another. There's new stuff coming out every single day, there's old stuff that people like me are just using for the first time and stuff like that, so all right, um holy majoli, uh. Phillip, thank you so very much for that super chat. That was amazing bud.

That's amazing. Thank you um. I i'm dumbfounded by that that thank you bud. That was really really nice of you.

Okay, it's a great way to support the channel. Thank you so very much. Okay, um: let's see what else we got going on in the chat that i'm missing, um uh carrier uses them on the chillers aqua snap and also the train screws to prevent flooding back. I don't know what you're talking about.

Oh head pressure. Yeah, i don't know um, i probably walked into that one. So let me see what else we got going on in here. Um does measure quick work on refrigeration side or just hvac, roger betting, court uh yeah.

It works on the refrigeration side, but it's still in a beta mode. Anybody can use it, but just know that it's not completely dialed in they haven't really been focusing on the refrigeration side. So it's really not going to be too much different from the refrigeration to the air conditioning side, if you're doing supermarket refrigeration or working on cases and things like that, the refrigeration mode in measure quick, might be a little bit more useful than someone like me. That does light commercial, refrigeration, walk-ins and different things like that.

Um it you know even in air conditioning mode. It still gives you all the necessary information, but the refrigeration mode, just kind of changes, a few things um so yeah, it's definitely usable for sure, uh flex. Ortiz, thank you so very much for that. Super chat bud.

Okay, um! Let me see what i'm missing in here. Uh head pressure. Controls can kill compressors. I know prime time.

Prime time has never been a fan of head pressure, control valves, um, let's see uh. What am i missing, i'm looking through the chat right now. What is my take on 410a being phased out in the future of refrigeration, a refrigerant in our industry, flex, ortiz, so refrigerants um, since before i started in hvac, there's been several refrigerants as i came into hvac in the mid 90s as a kid working with my Dad and then uh, you know, towards the late 90s early 2000s, officially becoming a service technician in this industry. Refrigerants have changed, there's always new flavors of refrigerants coming out every single day.

The best advice i can give to all of us is that assume that everything you know about the types of refrigerants that you deal with is going to change tomorrow. But the fundamentals: don't change, don't focus on refrigerant pressures: okay, because from each flavor or each different, refrigerant type, the pressures are going to change the pressure temperature relationship is going to change. They add other gases, their blends, their multiple mixtures, different things like that they're multi-component refrigerants. But the temperatures don't lie when you understand how the temperatures work so stop focusing on the pressures and focus on the temperatures when i'm looking at my gauges when i'm looking at measure quick or anything, i look at the pressures, but then i focus on the temperatures.

The saturation temperatures, the saturated temperature of the refrigerant in the point at which it's being measured, whether it's the evaporator or the condenser, and that's what i focus on because from every different type of refrigerant that those pressures are going to change right. But if i'm working on an air conditioner that has r22 or 410a for the most part, i'm looking for anywhere from a 40 degree coil to a 55 degree, evaporator coil on the evaporator side right. So if i just look at the saturation temperatures, it really doesn't matter if i'm working with 410 or 22., i'm looking at the temperatures. Okay, so there's always going to be new refrigerants.

Okay and to be honest with you, if the hippies had their way, we wouldn't have any air conditioning and we wouldn't have any refrigeration. Okay, we would just be like one of these countries that just lives out of shacks and that are made out of you know. I don't even know that we're - probably not even gon na, be able to if the hippies had their way. We probably wouldn't be able to use wood or anything like that.

I mean there's always gon na, be people trying to do different things. Okay, so you know i'm not too worried about it. Change is inevitable. It's going to keep coming just understand that, as change comes, our jobs are going to be more and more needed right.

We're going to be the technicians that know how to work on this stuff, and we have new things to learn it's job. Security is what it is every time they release a new refrigerant, there's new ramifications from it. Oh this refrigerant doesn't mix with this oil. So you got to change the oil or when you change the oil uh, the o-rings are degraded or whatever, and it's just more stuff for us to have to do, and you can be frustrated with that or you can embrace that and own up to it and Know that now you have job security, because now, in order to change to this new refrigerant, we got to do do do do all this different stuff and we get to sell that to the customers.

So um refrigerants are always going to change all right. Let's see what else we got, what am i missing? Um is work slowing down for me in washington. It's slowing down hard vlad um. You know work is slowing a little bit, it's not dead yet, but yeah.

It's definitely slowing down um the winter time is actually my favorite time, because it's when i get to take a little time off work and craze things aren't so crazy. I still have a backlog of construction uh. What i call construction, like my my installs and retrofit jobs, so i've got a walk-in system. I need to change out, that's been leaking.

I've got um a change out that i did uh. Let's see, i did that change out probably four months ago, but we replaced five package units on a roof because tweakers got up there and stole a bunch of copper and drain lines and everything. Well, we did that install and then, when we did that they didn't send everything that we needed for the install we needed full economizers for every ac. So i have five economizer assemblies sitting on the back of my shop.

They just haven't been a priority, so we've still got to install those we've got all kinds of install work that i'm it's slowing down enough, that we can start scheduling some of that work, but yeah it's definitely slowing down a bit um. Let me see what else am i missing in here um. Let me see, i saw some good things up in here hold on just a second. I already see that one.

What is my opinion on the california high-speed rail project? Um, i'm not going to get political in here. Um yeah, we're not going to go into that one. So um that turned into a giant political mess, so don't even want to get involved. Um.

Let's see dave dave johnson saying that measure quick. One second says overcharge and then two seconds it says: undercharged uh, i know kind of what you're talking about dave. You have to really really let the system stabilize out understand that when you are using something like measure, quick, okay, i'm going to be honest with you and don't take this the wrong way. I'm not flexing on anybody.

But honestly, i don't really use the diagnostics and measure quick. What i use measure quick for me personally is to consolidate all the information that way i can come up with my own diagnoses. Okay, it puts it all in one place, i scroll between three pages. I look at my vitals look at my airflow and i say you know what i have really low airflow.

I have really low superheat, i might be overcharged, but more than likely it's going to be an airflow issue causing the really low superheat. So you know - and i look at it like that i'll occasionally look at their diagnostics, just to see where they're pointing me sometimes they're right, sometimes they're wrong. But let's say this too measure. Quick in all honesty, from my opinion is really meant for residential split systems.

You can use it on package units, but it's really meant for residential split systems. So if you're trying to use it on commercial package units, it's going to be a little bit hard and some of the things aren't very practical in a perfect world when you're putting air probes in a package unit, you shouldn't be putting them in the side of The unit you should be going down and putting them in the duct work you know so that way you can be as far away from the evaporative oil as possible, but that's not very practical when you're using working on package units so oftentimes we'll shove it in The side of the unit, so then it might see really really cold supply air temperatures because it's really close to the evaporator or it might see really high discharge air temperatures when it's in heating mode again, because it's too close to the heat exchanger. So you have to kind of look at it and the way i preach measure quick. Is it's not going to do your job for you? It's just there to consolidate information and get you in the right area.

So that way, you can come up with a diagnosis, but measure quick is only as good as the technician applying the tools to the system. If you put the liquid line, temperature clamp on the discharge line, and then it tells you that your sub cooling is through the roof. Well, that could lead you down a path that you don't even know where you're going. So you have to be a technician that understands what's going on, so in no way is measure quick there to do our jobs for us, it's just there to consolidate information, give us a helping hand, not just in the right direction, but we as technicians know have To know how to interpolate, when information is incorrect or when something doesn't seem right, we have to be able to look and say wait a minute.

You know there's been times that i've been working with it, uh there's some bugs that i found and measure quick and different things like that, and it's like wait what's going on here and then you realize oh, this is wrong. You know. So let's change some things. So all right, let me get down to the bottom of the list on systems on the systems keep coming video.

How close was the arcing leading to an explosion? Honestly john deere fan - i don't remember that video, but i don't think it was ever gon na be an explosion um. I i i'm yeah. Let's see uh miguel martinez uh. He says there's several people on here that want to know.

If i can, please talk about epr's, evaporator pressure, regulators, okay, so um talking about eprs is uh is something that i really need to kind of prepare for. Uh, i'm not going to be able to fluidly come out with that information uh. You know explaining everything very uh explaining it properly, so i need some time to kind of prepare for those questions. So if someone does have a question like that, like the epr send me an email to help me remember and i'll do some research that way, i can come out with the right information, because i know how they work, but it's a matter of explaining it properly.

In the way that i like to explain things and - and i don't feel comfortable talking about them right now - because i'll just mess everything up and confuse the hell out of everybody - um are economizers worth replacing. Most customers don't want to replace them at your job. No vlad most customers don't want to replace and or repair economizers, because they're, a serious money maker, the sensors always fail. The motors always fail to be fair.

The economizer manufacturers expect that the customer is going to do proper, preventative maintenance and, with that being said, most of these customers don't want to do a proper preventative maintenance just because they have you come out. Monthly to clean equipment doesn't mean that they're actually paying you to clean the equipment properly. Most customers just want you there to change filters, hose coils blow drains out and move on with. That being said, let me cross some things off my list and actually want to talk about something else that i have on my list right now.

So i'm across these two things that i already talked about. I already talked about that one um. Let me see so someone had asked me a question: do myself, does my service company inspect contactors on pm services? Okay and that's a great question. So, yes, my service technicians, um, you know as part of our preventative maintenance.

We will open up the electrical section and look for anything scary, but the customers on any of my preventative maintenances do not pay you enough to thoroughly go through and do voltage drops and different things like that across the contactor. So essentially, when we're paid to do a preventative maintenance service on any of the customers that we do service for right now, they typically just want you to hose off the ac blow out the drain. Change the belt um open up the electrical section, make sure there's no nothing, melted or burnt, or anything like that turn it on check the temperature split across the evap and uh or across the return and supply side of the unit and move on. If my customers wanted to do a proper preventative maintenance service, i could probably spend up to eight hours per package unit thoroughly going through the unit tightening every screw.

You know checking current on everything, cleaning every coil, so splitting condenser coils most people - don't so short answer is yes, they have us check the contactors, but they don't have us. Go in depth. Pulling covers off looking for different things, there's not enough time, typically in what they allow us to do. Um in a recent video uh, the the train package unit, where i said the breaker cap breaker, was tripped, i i said some words in there and explained my process of going through a system that has a tripped breaker, and i want to stress to everybody out There i suggest that you never ever reset a breaker until you have checked the system out as best as possible for direct shorts to ground for locked up motors for obvious electrical shorts and different things like that.

Okay, there's nothing worse than turning on a breaker and having it blow again, because you're potentially causing damage somewhere. I've told a story before i'll. Tell it again i'll do a paraphrase version. I was working out a golf course.

It was an emergency service call in the middle of the night i went out there, the fuses were blown i put in new fuses and i turned on the disconnect switch and um all of a sudden. The fuses blew again, but it actually wasn't the fuses. What blue was the main breaker downstairs, so you have a main breaker that controlled an entire panel, and i went to go reset that main breaker and it wouldn't reset the breaker actually broke internally when it had tripped now was it my fault that the main breaker Had broke no because it was probably inevitably going to break eventually right. There was something going on with it, but could i have possibly prevented it from happening that night? Yes, by checking the system out before i replaced the fuses and turned on the disconnect.

What ended up happening was the system had a grounded compressor, so it instantaneously shorted the ground and tripped the breaker okay um. I learned a lesson and that golf course had to go without an entire electrical panel for half the building for an entire weekend, because it was a weird 4a volt breaker, the electrician. I don't know the electrician couldn't get it whatever, but that could have been prevented and i learned a lesson and from that point forward i have always gone in and before i reset breakers, you always look. You check things to ground.

You spin, the motors. You look for obvious issues, okay, so i uh showed examples of that in my recent video where i went up and i went through everything as best as possible before i reset the breaker, and i found some issues that, in my opinion, could have caused the breaker To trip now it's also possible that the breaker was just bad. It happens, okay, but the way that i look at things is in my head: a breaker doesn't just trip and a breaker doesn't go. Bad doesn't just go bad, so i always assume that there's something in the system that's wrong, so i do my best to check out the system and then, if i can't find anything, then you do the one two three please don't blow up and you turn it On and see what happens? Okay, so um! I had a commenter - and i want to address this - and please do not take offense to this.

If you are watching this stream right now, okay, the guy that commented on this - i'm not gon na, say his name, but he told me in uh. You know i'm paraphrasing that my closing words are way too long, okay and that i should probably research. My analytics analytics are away as a content creator on youtube. I can look and see.

I can see all kinds of things i can see. You know the the gender of people that watch my videos the times that people watch my videos um. How long people watch my videos so anyways. The commenter was telling me that i should probably investigate the analytics and see how long people are watching my videos and see if people are actually watching the closing words on my videos.

Okay, so that's a great point that the commenter was making okay, but the difference between myself and other youtube creators is, i don't really make these videos following youtube's best practices? Okay, i make these videos bottom line for my employees. Okay - and i make these videos for you guys, but i have useful information in there. Okay, so just because majority of you guys are not watching the closing words, i'm not going to change the way that my channel is because, in my opinion, sometimes some of the most valuable information is in the closing words. I address my mistakes.

I address different things. So yes, there's gon na be sometimes that the closing words are longer than the video. It's okay! If you guys don't like it, if the person that's watching, doesn't like it again, i don't mean any offense, but i'm gon na continue to make the videos the way that i make them. I beat to the tune of my own drum.

I don't really follow what people say. I should do okay, i have sponsors for this channel, but those sponsors are the type of sponsors, refrigeration, technologies and sporland. That don't demand things of me. They don't require things of me.

They like the way that i do things. I've turned down other sponsors and avoided other sponsors, because i know that it's going to get to the point that they're like oh, you know you need to address this and you need to address that. That's not how i want to run my channel. This is my channel and i'm going to do it the way that i like to do it now, i'm always open to feedback.

So don't let me deter people from emailing me and again i mean no offense to the commenter that sent that. I appreciate your feedback and i appreciate your concern okay, but understand that if you don't like the closing words, it's really easy just to not watch them. When the video ends hit, stop and move on, you know there's no reason to be upset or frustrated with me, because the video is going to keep going on. You know just just just stop watching and move on or if you don't like my channel you're free to move on.

Okay, but again i don't mean offense, but i'm gon na make these videos the way that i see fit and, in my opinion, there's really valuable information in the closing words you know and also um. I also do things differently and i'm gon na tell you guys something that i've never really told people. Only certain people know this, and i don't do this all the time, but sometimes in the closing words, i give things away. Okay, i find it ironic and kind of funny sometimes on these live streams.

After i say the live stream is over. Sometimes i actually come back on for another 20 minutes after the music plays and everything i'll just randomly come on and i'll do giveaways. Okay, just because i kind of find it funny, the people that hang around and actually watch are like the core group of people that actually do that stuff. So i'm not saying that i'm going gon na do that every single time, but i've done it a lot in the past um.

So i i always just kind of do things my own way, i'm different uh, you know, or maybe i'm normal and everybody else is different. I don't know how do you say that all right, so i'm gon na, get to the chat and see what i'm missing in here and uh. Oh see, there's another one. I already answered that question um, looking to see what i'm missing uh right on bud jm.

I appreciate you staying till the end man, that's awesome, so uh scott! Thank you so very much uh for that super chat. Man, yes uh. I do plan on going to the ihacky trade show in november, which is a local trade, show hvac trade show in pasadena. California, i do plan on being there.

I usually go early in the morning and stay for majority of the day. I will also i also plan on being at the ahr trade show in las vegas this coming uh january, and then i also either virtually or in person will be at the hvacr training symposium at the kalos headquarters in uh claremont florida in february of this year. So, yes, i do plan on being at the ihacky trade. Show, though, yes, um definitely send me a message, scott and we'll try to meet up if you're going to be there.

So i had a commenter asked me a question: do i have a recommendation for what school is the best school? I have no idea where the commenter is at okay, but no, i don't necessarily have a recommendation for a trade school. I am going to say this. First off, i fully believe in a trade school. I believe that as a service technician, you should go to trade school while you're working or before you work.

Okay, i also feel like you should do a proper apprenticeship and understand that you're not going to learn everything in trade, school and you're, not going to learn everything in an apprenticeship. But if you put the two together along with working in the field, you're gon na learn a lot. Okay, i want everybody out there. That's considering going to trade school to be very careful about the trade schools that you choose.

Okay, because there is some really bad schools and there's some really good schools, there's really good for-profit schools, there's really good, non-profit schools. Okay, it's it's! It's really a gamble, but i will say if you go to a trade school and there's kids in your classroom that clearly are not doing the work are not pulling their weight. Are not you know that should be out of the class, but they don't kick them out a lot of the times. Those are going to be for-profit trade schools, because they're literally only concerned about money, but not every for-profit school is like that.

Okay, but there's a good majority of them that really are concerned about the money, even in some of the community college programs, which are the not-for-profit schools, there's some that won't get rid of students which kind of frustrates me. Okay, i believe that if you go to a trade school and you're not cutting it, i think you should be out. I don't think you should be in there wasting the teacher's time and taking away from the time that each of the students gets. You know if you're just wasting time, you know like, i feel like school, should be able to kick you out.

So do your research on trade schools call the local service companies in your area? If you want to get into the trade and ask them what schools they recommend? Okay, even if you're not going to go work for that company, just call the companies and say hey, i'm a local kid and i want to get into trade school. I'd love to possibly apply at your company someday, but in the meantime i want to get started in trade school. Do you have any that you recommend and find out what schools, the local companies recommend? They'll answer your questions. You know and to be honest with you, a lot of companies will hire a technician before they go to trade school like uh.

In the past, even myself i was working before i went to trade school and then i went to night school at a local community college and took night classes in hvac and learned hvac. I worked during the day and learned at night and that worked great for me. So that's one of the plus sides to uh community college style trade schools because oftentimes you don't have to pay up front. You don't have a large commitment.
