So, 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, hello. My viewers, i got to give credit where credit is due. Dr zarkloff, i used to love watching that, if you guys don't know who that is, uh he's an og, hvac youtube guy um and he was hilarious at just every one of his things was hello, my viewers, that's how he would start every one of his videos And it was great um on another note, so i'm questioning whether or not i don't think my internet is working again.

Hmm, let me know, is it really blurry, for you guys cause like the the preview that i'm looking at right now looks pretty crappy, so we may be having some problems with this stream. I'm gon na wait for the chat to catch up here, real quick and see what the chat has to say about the internet quality um hold on. I know there's always like a 10 15 second delay and when i ask a question and what the chat okay, so people can see it all right cool. I i think that my uh, my i don't know, what's going on my internet's kind of wacky or something like that, so all right cool sounds great sounds great, so you know um it'd be kind of funny to do like a video or something like that with All the old school youtubers that'd be kind of cool.

If someone can orchestrate that you know uh mike pettinato or jim patnato and uh mike penato, that's mike pettit is a manager of a local supplier used to be a manager of a local supply house near me, but anyways uh, jim pettinato and um dr zarkloff, and All those different people that'd be pretty funny. If we could get those people onto an internet thing, that'd be pretty pretty cool right on sweet yeah. Everybody in the chat saying the audio and video is good. Just must be on my end, so i am all over the place with all the different ideas and different things that i have going on um.

You know i have so many different things and the fire burning and all this stuff and people reaching out to me saying: hey: do you want to work with me on this and that and this i genuinely need more time and then in the midst of everything, Because i'm 80d much or whatever you want to call it just plain crazy. In my head, i decided that i'm going to move my office, i'm not going to use this room anymore, i'm going to use a garage room that i have because it's much bigger and i'm going to totally convert that into a studio. That's like soundproof and everything. So uh yeah it'll be interesting.

What kind of got me thinking about that was last week i was lucky enough that ty branaman was coming into town and he messaged me and so or last week, maybe the week before. I don't know a couple weeks ago. One of the first monday that i missed the live stream tai was in town, so him and i went out to dinner with his wife and my wife. It was really nice to get to to to hang out with him and ty's a really really cool dude.

If you guys don't know who ty brennaman is come out from the rock, where you're living under and uh find his youtube channel, it is great. He just has such an animated way of teaching and things so anyways, but um that got me thinking that i really would like to be able to do this with people. More often, you know if tai comes into town, like i'd like to be able to do a podcast with a couple different people in him or a video whatever you want to call it vlog. I don't know what you call it but um.

I wanted to do that so that kind of i can fit one more person in here. Brett knows, but it's kind of tight. You know like i wish that it was a little bit bigger, because this is this little room right here. I think it's a 10 by 11 room.

It's just really made for you know one person it's not really made to have multiple people, so i'm trying to do that and then, in the midst of that i've got normal work stuff going on and um. You know and another thing too, i post it and i'm going to address it a little bit too. I don't want to like blow everybody up with the mental health stuff, but at the same time i feel like we need to get rid of the stigma. Um.

Thank you, everybody for all the kind words that everybody said on the post that i put out there on social media about my mom and my grandfather. If you guys didn't see the post follow my social media, i'm on pretty much all the platforms at hvac. Our videos, one word um, but uh. I posted that like this last week, i was just having a hard time.

Actually it was uh yeah. Last week i was having a hard time and i didn't know why i was just like in a bad mood or whatever and uh. Then i realized because previous to that week i had gotten word that my grandfather had passed away, which i kind of felt like. I was okay with you know, and then my mom had passed away a few months ago and uh, but it was my mom's birthday the day that i wasn't feeling good.

I knew it was her birthday, but i didn't it just didn't click you know. So, by the end of the day i was just kind of like feeling down or whatever, and then i realized i was like. Oh crap. You know it was my mom's birthday and then just got me thinking about my grandfather and all that stuff, but i mean that's normal, that's grieving right, but i wanted to you know the reason why i posted was not so much to to to to get attention Or anything like that, it was just to raise awareness that it's okay to have bad days.

You know when your head's, not in the game, when you're not feeling good when you're depressed when you're. Whatever, like talk to someone, you know, don't don't hide that stuff because from experience i've gone through this um i've seen a doctor and for me i don't know if it is the same for everybody else, but the way that it works for me is. I was diagnosed bipolar. I was all these weird, i don't know acronyms and different things and i don't even understand half of this stuff, but it's something that i have to live with for the rest of my life.

Like i saw a doctor, i took medication. I did an 18-month stint where my wife said. I slept the whole time because i was on luxopro, i think, or something and but i mean it helped me, you know and it helped me. You know and seen a therapist and all that stuff, but regardless what i got from all of that was that they didn't cure me.

They didn't make. You know the the the craziness in my head go away. They didn't make the voices go away. You know any of that stuff right um, but they uh.

They just taught me how to deal with it and how to cope with it and how not to be an angry person that punches holes in the walls. Because that's what initially made me go to the doctor in the first place was, i got really angry and i used to bottle stuff up and not talk about it and i punched a wall and it felt so flipping good. But then, when i realized my my hand went right through the drywall and was like you know three quarters of an inch from the stud it's like wow, you know if i had to hit the stud i'd, have busted my hand anyways. All this stuff rushed through.

My head - and it made me realize like that, felt too good and i enjoyed it too much, and so i decided to go see a doctor and lottie doll that stuff, but i just want to bring to light that it's okay right, i mean we. We have this stigma that um that we feel at least the way that i did and and the way that my family, some of my family members around me, have kind of felt too that, like that's, not stuff, you talk about and it's kind of a bummer, Because it really should be stuff, you talk about um, you know talk to family talk to friends, so you know i wasn't feeling too great last week, so i messaged my friends and i messaged you know i messaged. I talked to my wife and you know they kind of helped me through it and it wasn't anything bad, but it's okay. You still go through times like that and and i'm grieving in a way too.

You know so um, let's see what else we got in here, uh yeah, i i you know again, thank you so much for the nice words i'm reading through the chat right now, but you know it's not so much that i want to bring, and i mean There's nothing wrong with it, but like it's not so much that i'm like an advocate for you know, everybody needs to take their mental health days and all that stuff, but i mean there's, you know i mean sometimes you do need to take some time off and You need to to work on yourself for sure. Okay, we can't be the technicians that we're meant to be if we're bogged down with other stuff too and the mind is no joke. It messes with your head and it'll, take control of you. So you know you need to talk to people so um.

I uh, of course, want to answer questions that you guys have in the chat i'm going to talk about emails and different things that i got youtube comments. I got a few of them. I'm trying to cut these a little bit shorter, so they're, not as long um, but you know we'll see uh we'll see how it goes. Um.

One thing that i wanted to talk about was uh. Obviously i took some time off. I haven't done a couple. Live streams haven't done a couple videos just because i was busy it's been kind of not so right.

Lately like up and down and up and down but um. You know there's a lot of talk in the industry about a lot of changes. Uh coming out. If you guys haven't and didn't already um, if you guys search uh shoot, i don't know how i don't know how to do this, but uh, there's a there's.

A new youtube show that popped up yesterday called the the hvac grapevine. It's a couple of the hvac. What do you want to call it airflow guys, not airflow, but come on. I can't think of think straight, but anyways, it's it's.

It's three hvac guys that are doing a show. You guys should definitely check it out. The the the hvac grapevine is what it's called, or something like that so um, but anyways uh. You know they were kind of talking about this and uh, something that they brought up was they were talking about the co2 compliant units that are coming out, um uh pretty shortly here right.

You know we had uh seer ratings, well, they're, upping that across the country they're going to start making uh. You know these. This equipment be more and more efficient right, and so one of the things about cr2 is it's it's even more efficient than the previous. I don't know why they just couldn't call it seer, but they have to call it cr2 because it makes it seem more special or something but um.

You know. Another thing: that's happening is they're going to a lot of the a2l refrigerants. There's nothing to really be scared about when it comes to the a2l refrigerants uh, you know any of them. I mean even the a3s, the hydrocarbon refrigerants, the flammable ones.

It's not so much that you need to be scared. It's just that. You need to follow certain procedures, ironically majority of the procedures with hydrocarbons. R290.

R600A. Basically, the requirements are the same requirements that we were supposed to be doing from the beginning. If you go read any manuals from the early 1900s, you know when they were talk when they were first, you know coming up with the concepts for heating and air conditioning and perfecting everything their stuff that they told you to do back. Then we kind of forgot about and we kind of skipped it right and even jim bergman talks about it.

You know if you read some of the old books like this one right here, review a vacuum that jim bergman and brian orr had revised. But this book was originally published and let's see what is the publish date of this book, i don't know if there's an original publish date. Yeah. That's interesting, there's not a published date in this book from the original one, but this book was written a long long time ago.

Oh there, it is right, there 1959 was then, when this book was first published okay, yet you can talk to people and you can hear them say you know, oh, that that uh that silly vacuum nonsense. You know that stuff's all new and even um uh brett wetzel and kevin compass on advanced refrigeration podcasts were just talking about this on the recent podcast. Yes, i do listen brett occasionally. I don't listen to everyone, but i do listen so anyways they did a podcast on evacuation and they were kind of talking about it too.

But the thing to understand is you know, using micron gauges and and having big hoses. That's nothing new. That was from the beginning. We just forgot it.

Why did we forget it? Well, because we realized that the refrigerants they were using back then were very forgiving they could handle. You know the systems could handle a few non-condensables. It wasn't that big of a deal because they were massively oversized. They were like six seer units.

They were massively oversized condensers, you know. So there was a margin of error there. You could get away with some of that stuff right and um. You know with the the the the chlorinated refrigerants and mineral oil and all that stuff.

You know it was very forgiving too. So, even though the the concepts and the the best practices were still there, they just kind of got relaxed and forgotten about. So now we're diving deeper into them, and you have these people saying all that new vacuum stuff there's nothing new about it right, but the point i'm trying to make is you know these new high efficiency units and these new codes and all these different things are Just another opportunity for us to make money, and it's not really that hard, i mean realistically it's our job. Our job is to fix this equipment right, so they're going to change something you know, but remember when you first started out, you had to struggle to learn, but then you kind of got in a comfortable zone and you're just kind of relaxing and cruise control.

You know i mean we just got to slow down a little bit, go down, learn a few new things and come back up then we'll get on cruise control for a while again and then you know we need to not be afraid of change, because change is Inevitable and it's a great way to make money right and we have all the opportunities us as technicians right now, okay um, let me see looking through the chat um, what hvac school do i recommend going to price is not an issue joshua, it's not so much About money, i'm gon na get back to my rant here in a minute too, but i'm gon na answer some questions. Joshua! It's it's not about money. Man! Any school is gon na, be what you make it: okay, so um personally, my preference is, i go. I went to a community college near me: mount san antonio community college.

It's an amazing school. They have a great refrigeration and air conditioning program and uh. It was low cost because it was a community college. Okay, there's good and bad community colleges, there's good and bad private schools it, but they're all about what you make it.

You need to understand that nobody is going to make you learn. You have to learn yourself. People are going to give you tools that can help you to learn better and it's your responsibility to use those tools and figure things out on your own. So do i have a favorite school, not necessarily i don't i mean i'm sure people in the chat can say the schools that they want to go to.

It really depends where you want to go in the industry too. Do you want to go? Do you want to get a bachelor's degree in hvac? Well, i think there's only still one school. That does that i believe and it's ferris state university in michigan um. You know i mean so it really depends on where you want to go uh.

You know. So i mean it is what you make it. Hopefully i mean i know i kind of just answered. Your question is: is that okay? So i heard adam and and uh some of my friends talking about the sandler effect.

Is that answering the question with the sandler effect? I have no idea. I just heard it's like about changing the topic and whatever um all right. Let me see what else we got going on in the chat. You almost forgot what it's like to work on new equipment.

You mostly work on older stuff, uh, jason, yeah, that's interesting! You know every day we've got new technology coming out new fancy stuff. You know someone made a comment recently that i was going kind of silly and i was using a computer on a job. I i wasn't using a computer if you see what looks like a computer on the job, if it's a newer video, that's my tablet. It just has a keyboard um, but i mean we have all these new tools.

Why not use them uh? I appreciate uh analog gauges and and the og tools like i appreciate them, but you know the new stuff does so much, but, along with the cool stuff, it does there's also some nuances that you have to work through and things that you got to figure out. Um i was recently working with a piece of software that that has digital things and and i'm noticing some issues when you sync it up to the app one of these tools and it's like okay, so that could be a problem. So i bring it up to the manufacturer, you know i reach out to them. That's one cool thing that this whole platform has given me.

Was it's given me an inside track? I have a few friends, and all i have to do is message. Those two or three friends and say: hey: do you have a good contact at this company and boom? They give me the right to the top. Where i can start. You know making changes and stuff um.

So it's it's cool to have this platform to be able to do that. It's very humbling. So thank you all very much. Let's see alaska thanks so much for that super chat man.

I appreciate that that is amazing, bud. Um all right is that motor out of the captive air exhaust fan cyborg. Yes, it is so that is a video that i have not made yet um, it's kind of difficult footage to add edit, but uh yeah. That is a bad motor, um and uh.

I was doing some testing on it. It's pretty cool, it's pretty cool little video. If i ever get down to editing it, you know what what's interesting is most the videos that you see. Most of them are the really easy videos to edit.

I have some really interesting ones, but boy man are they complicated to edit, it's really difficult, so i've just been sitting on them and every once in a while, when i get bored i'll i'll, sit down and start editing, one of those complicated ones, but i just Got this whole hard drive full of them um. Let me see what else we got should products like rx11 be used or just liquid and suction line, filter dryers for burnouts, uh, nikolai. I believe that is your name. Forgive me if it's not, i don't know if i butchered that okay, so here's my take on this all right, i'm not a genius, i'm not the best tech, i'm not a chemist or anything but my take is.

I don't understand the science behind some of these products or these additives or these chemicals i mean you can read what's on the package and it says it what it does. But how do you quantify that? How do you prove that it actually does that stuff? Okay. Rx11 flush um i've used it for a good majority of my career. I used it because the supply house told me when you have a burnout, put an acid neutralizer, use the rx 11 flush and call it a day.

Interestingly enough, do you know why it's called rx11 because we used to use r11 refrigerant because it had great solvent capabilities and we used to flush a system out with? Well, not me, but i mean the industry used to flush systems out with r11. So if you had a nasty burnout, you had some r11 you'd purge it through the system chase it with nitrogen and push it out. Rx11 is just an interesting play on an acronym and it is there to uh mimic the properties of r11 uh. But, interestingly enough did you know i'm going off on a tangent right now too, with r11 for majority of my career, i used it and i realized that i was using it wrong and i wasn't really being effective at all when you do use rx11 right, whether You choose to or not when you do use it.

Let's say you're doing a line set. Okay! What you got to do is you got to go to the opposite end of that line set you need to pinch it down and create an orifice, a restriction. So that way, when you put the rx11 in there, then you blast it with nitrogen. It builds up and the back pressure scrubs the walls of the line set and it's a solvent, so it cleans them off and then theoretically, it vaporizes or boils off and then makes it out of the system.

But the question and my concern about rx11 is what is left behind. Do we know that nothing's left behind? Is there still solvent in those walls? That's what concerns me about using it. So personally i choose not to use rx11 anymore. I personally will just do nitrogen and uh dryers and then, like i just did it the other day.

Did i make a video about it? Yet? No, i haven't made a video about this too, but um i had a filter dryer that plugged up. So when i installed it, i kind of had a feeling that there was contaminants in the system. So when i replaced the filter dryer i put in ball valves, so i went back a week later turned the system off ball. Valved it off got rid of the refrigerant and then changed the dryer again without having to recover the entire charge.

So on burnouts, if given an opportunity, it's a great idea to go ahead and do that put oversized dryers in there. Maybe even put a flare dryer in depending on the situation and then go back and change the dryer. And then you don't have to pull the refrigerant out again, like it's a real cool way, so i personally don't like using rx11 flush, nothing against them. I've never seen anything bad happen.

I said that i used it for majority of my career because i blindly trusted what people told me to do, and i didn't do my own research. So i once i did my own research, i just kind of decided. You know the manufacturer doesn't want me to put that in there for a reason. That's another thing too.

With most of these additives, i was listening to someone from copeland uh recently talking. I don't know if it was don gillis or someone else. I think it might have been don gillis. Don gillis is another great person to follow on social media.

If you don't already too but um, he was talking about how how much money, copeland and emerson makes a company pay to have their products tested. So that way, copeland or emerson will potentially give them an approval right. So a lot of companies aren't that confident in their product, if they're not willing to put up the money that copeland requires to have that product tested out properly. So that way they can give a yes or no to it and that's an interesting concept, and i appreciate and and praise emerson copeland for doing that, because, basically, it's mainly not all approved right and if it is approved, what's interesting, there's a product out there.

That says approved for, and it says, a specific application within that what a copeland compressor works for it's, not the entire gamut of copeland compressors, that's another thing too, just because it says manufacturer approved on there does not what manufacture all of them, like that's a play On words, that's marketing right, a manufacturer may have said yeah. This can be used in this exact situation and then someone just their lawyers got involved and made it look like you know: copeland approved it for everything, so i try to stick to what the manufacturers typically want you to do, because i kind of feel like they're. The best person to trust on that my personal opinion. So, let's see what else we got going on in the chat um, let's see ryan murray, says you worked on a uh lebanco exhaust fan today had a weird motor mount plate where it gets held up by the belt and the fan pulley.

You had to change to a bigger belt, so it would sit on a flat plate ryan. I am very intrigued by that. Do you have any pictures of that? If you do, i would love to see them. If you could send me an email, um, hvacr videos, gmail.com um, you know what ryan i'll give you my special email address.

Don't tell anybody else. It's c stevens s, t wait! No! It's not never mind it's chris at hvacs.com! That's my secret email address that nobody knows about, so don't tell them: okay, um, let's see what else we got going on here. Am i seeing straight condensing units having accumulators to help with lower temp climates, kenneth um? Yes, i am, but honestly it's not about lower ambient climates. A suction line.

Accumulator is a great great resource, no matter what and i would highly recommend it on almost any install okay, because you know, depending on varying loads. That's when the real problem is, if you have a varying load um, you know you can have times where you know that system's really really going to be trying hard to cool the assist. You know the the space down and you know you might be flooding a lot of refrigerant back depending on. If you have a failing, expansion valve or different things like that, so i think an accumulator should be a necessity almost like something that we always install.

Unfortunately, i don't sell them that much right uh, because what i find is on the aftermarket side, there's not a great stock of them in the supply houses. They don't typically have it like boom. You know um, so the more supply houses start to stock them. I think it's a better thing we can put on our systems, but on the same side, when we have higher efficient systems with exvs and stuff, you know the the the the chance of of having flood back issues is smaller and smaller.

So, but i think an accumulator is a great idea, but let me let me let me say you know a large portion of the industry hates suction line. Accumulators. Oh just cut those things out, i've been told many times by manufacturers. Yeah just take that accumulator out.

I guarantee you're going to take that out and it's going to be full of oil. You know - and it's like that was one thing too. If you ever open up accumulator um, especially uh, if you have a bad compressor, if you have a bad compressor and you you take the compressor out and you pour the oil out and you find out that it's low on oil there's a good chance that it's Going to be in the accumulator, but why do we blame now that dumb accumulator, it's the accumulator's fault? It's really not! Okay, the science behind an accumulator is down at the bottom of that accumulator. There is a tiny port, a tiny hole.

It's a pickup port right and it's for when oil makes its way back through the system, because they're trying to keep liquid from flooding back to the compressor. Therefore, the design of an accumulator. I don't have one right here, but the design is basically the reverse of a receiver and um. We need oil travels with the refrigerant, so there will be oil.

That starts to build up in that accumulator and it has a little tiny hole at the bottom of the suction at the bottom of the tube, where it's a pickup tube and it pulls the oil back in. So if we don't follow proper practices taking us all. The way back to the beginning of this stream, when i was talking about some of the things we're supposed to follow, it's nothing new we've. It's been, since you know the infancy of hvac, but we kind of forgot about them is brazing with nitrogen.

That is a huge thing. Now, i'm not a perfect tech, that's going to say i do it all the time i try as much as i can, but brazing with nitrogen keeps those little. I think they're, copper, oxides or something i don't know whatever the technical term, but it's the black flakes and the lines those will plug up that pickup screen on the bottom of the accumulator, and that becomes a problem. Okay, so accumulators are good and it's not so much that it's it's because we're not following proper practices and we're being dumb dumbs that we we point the finger at the accumulators um, because majority of the time there's nothing floating around in that system.

If you do a system, evacuation you've got clean oil um. You know you shouldn't have anything in there, but it's from us brazing and installing the systems that messes those accumulators up a lot. Let's see do i know the main causes of ecm motor failures. Uh steven uh toten teeton - i don't know how to pronounce your name um.

Well, i'm gon na tell you right now: i'm not an expert in ecms, but i'm gon na tell you it's the cause of most motor failures on blower motors and different things like that is gon na be static um. I know they say that ecms are are, are better at you, know, controlling everything and they they're they last longer, but man they don't like being put in crappy conditions and um. So i would say ecm. Motor failures.

Um mainly happen because of that i would say the next thing is heat used in condenser fan motors and things like that when you, when customers, don't maintain equipment where the fan motors cooled by the air passing over, if you think you have a dirty condenser, it's Going to drive condensing temps up, it's going to make that area behind the condenser and the air finally making through the condenser is going to push that up into the motor and not help the motor to dissipate heat as it's running. So i would imagine i'm going on a limb saying that heat might be one of the causes to kill the the condenser fan motor ecms too. That would just be my theory now on the commercial side, i don't deal with ecms as much, but i do deal with uh vfds, a lot variable frequency drives and those we have a mass amount of problems with uh our power conditions here, because we don't have The greatest power conditions i was literally just talking to a buddy today on the phone and uh. We were having a comment about he's: doing vrf work.

That's my buddy rudy! What's up rudy um but uh, he does a lot of vrf work or he's getting into that and he was just talking about board failures all the time and then i brought up to his attention that you know: we've been having vfd issues and we're you know, And i've even talked to the manufacturers of the vfds again going back to being able to have a direct connection with a lot of these manufacturers, and basically the vfd manufacturer is like dude. We knew this was going to happen, but this is what the manufacturer that bought it from us wanted right. So you know they wanted to cut corners. They didn't want power conditioning you know, and so they have a high failure rate of vfds partially because of electrical issues and then also because they're installed in the mixed air cabinets on some of these ac's or the outside air cabinets where the condensers are at or The um compressors are at and they get hot too hot.

They get moisture different things, so you know um, what's the main cause, i would say power and uh poor install would be the main cause. Um carrier rtus with vfd is definitely gon na get a service call for it, yeah jason johnson, i mean you know i actually what's interesting. Is i struggled on the first couple vfds that i bypassed and then uh, and this kind of makes me laugh. So i struggled a bit with the vfds that i bypassed in the very beginning on the carrier units: okay, um, i'd, install contactors, i'd, try to power the the the contactor to reload.

You know to run the indoor blow motor. I tried to power the contactor from the thermostat board and different things like that, but then i figured out that carrier literally leaves the wires. You have a g and a common for 24 volts sitting right next to where the circuit board goes for that unit like it's, where a contactor should go. So it's kind of funny that they still use the same wiring harness and still run power over there.

But there's no contactor, so when you go to bypass a vfd now it's like plug good done. You know so and then it has. You know it'll last as long as that contactor will last and then, when the contactor fails, the contactor only costs. You know 60.

70 80 bucks, whatever it is so um. Let's see it's cool to see everybody in here. It's awesome, so many cool people. You guys thank you so very much for you know all the support.

It's amazing um, a couple more things i want to talk about on my list um. So someone asked me a great question and they wanted to know why i'm going to paraphrase this question and combine it and make it a bigger topic. So he had left a comment in one of my videos about a refrigeration rack and not understanding why customers would use them. So when i talk about a refrigeration, rack is a little bit different than my buddy brett, wetzel's, refrigeration, racks or kevin compasses, or any of you supermarket guys.

Okay, because i'm using a refrigeration rack, which is really just a multiplex system right. It just has a bunch of refrigeration circuits on one compressor or you can have multiple compressors okay, but we're not sharing common suction lines or anything like that. If you get into like a supermarket rack, there's reasons why they do those and those are very efficient. Okay, but on my types of systems, where it's just a multiplex system, it's a single compressor typically doesn't have any variable capacity, no unloading or anything like that.

The more circuits you put on that compressor, the more potential that you're gon na have issues. Okay, so let's say you have six circuits on a single circuit in a refrigeration rack on one of my roofs, okay, you, let's say you have six evaporators on it. Well, what are the odds that four of those evaporators, or maybe even five of those evaporators, are going to satisfy and you've only got one calling well? The problem is, is that compressor was designed and sized for all of those loads to run at the same time? So if each evaporator is a thousand btus, that's 6 000 btus of compressor capacity. That's needed to operate those evaporators right.

So what happens? If you have that 6000 btu compressor and five of those evaporators satisfy, and you only need one now. You have a massively oversized compressor, um right oversized in the concept that it's too powerful and it doesn't know how to slow down. So then it becomes oversized right um, those are called compressor killer systems, in my opinion, okay, that's what i call them and why would a customer choose those because they're cheap up front they're, the the install price, the build price of the restaurant? Is you know low when you're using a refrigeration rack instead of running a electrical circuit for six different condensing units, and you know um uh having the roofer do this and the structure built to have different condensing units all that different stuff? You know in the long run, separate circuits, separate systems would be a good idea, because if one system fails, you can change that. One system, if you have a refrigeration rack that has a common condenser and all the circuits, are going into it, and you have a leak on that condenser.

You now have to change the entire condenser if it's not repairable and you have to shut down all the other systems to do it so they're, not that efficient, um and and cost effective in the long run, but in in the the install price heck yeah put In a refrigeration rack, it's a great idea because the lower cost it's one unit, so um now so there's really not many advantages to having a rack system. In my opinion, i mean other than the price as far as longevity and serviceability you're, better off with separate condensing units and then in the long run when one of those fails it's a heck of a lot cheaper. So let me see what else now, once you start adding that's like a single component system, no variable capacity once you start adding variable capacity, vfds and different things like that. Of course, you can kind of tweak it and make it a little bit more efficient.

So um do, i think inverter technology will make its way into refrigeration systems soon uh yeah, it's already there laska um, it's not is is known, but um. It's totally there and i mean the variable capacity. Is there so um? I guess it's not a typical inverter system, but i mean it's the same concepts. An inverter system, in my opinion, is just gon na.

It's just a way to speed up and slow down the compressor with logic built into it. So that way, you know it can control other things besides just pressures. So, in a way, a refrigeration rack in the supermarket is probably the same thing, if not better, with all the different capacities and a single unit processor that runs it um, it's kind of the same concept now light commercial. I think it's it's gon na become more prevalent uh.

You know you it's in the residential market for sure it just hasn't quite jumped into the commercial side, but it's it's it's all there. It's that's the cr2 stuff too. I mean because they're not necessarily told you have to do this particular thing to increase efficiency, but they just basically give them a number and say you need to reach that so everybody's kind of coming to the same consensus but um. I i think it's here.

It's just you know, going to take a little time to become more and more popular, so um. I do want to ask you guys a question. I'm curious about emails from you, guys, uh. That would be great if you could.

Emails are the best because these comments are going to disappear and i don't you know, go back and review them, but i'm always interested in new things that i should do new concepts new tools. I invite your criticism. I invite your advice. Please email me: okay, um! I'm i'm not a little kid anymore.

I can take criticism, i'm okay! I learn from it. So if you have value and you're not a jerk, i i invite it so please send me an email give me ideas. If you think i can do something a little bit better, if you'd like to see me talk more about some certain topic, shoot me an email. Let me know: okay, um.

One thing that i'm curious about is you know torque wrenches. Do you guys use torque wrenches? I've never used them in my career period. Never, but you know i understand the need and the the older i get the more i think like you know, that could solve a lot of problems. So i'm really thinking about diving into the torque wrench side, but my initial research doesn't show anything spectacular.

It all seems like it sucks. I was kind of excited when i saw that milwaukee had a digital one, but my gosh that milwaukee one's like this long. It's it's huge, so um, i'm really interested in some new tool. Ideas too, if you guys have torx screwdrivers i'd love, one of those.

You know if you have torque wrenches that you really like. Let me know what types so i can research it. I really and i going back to the beginning of the stream again, i'm all over the place always have these different ideas, and i really really want to push on that tools channel that i have too. If you guys don't know, i have a tools channel with my friends hvacr tools.

We haven't posted on it in over a year, but we, like it's fun, doing those videos. It's just it's time consuming. You know i'm gon na tell you guys something, i'm actually getting to this weird point, where i kind of could really focus on the videos more than my normal job like i, the videos has given me opportunities and i see all kinds of different ideas and things That we can do, but it's that i'm at that weird point right now where it's like. Oh you know, my normal job gives me videos to film.

You know so it's like, but i'm i'm really thinking about pushing hard on the video stuff and i'd love to start posting more on the tools channel um. I'd also like to start bringing people into the hvacr videos channel, like i think, that'd, be a great idea too, to bring other people that i'm interested in working with and have them make videos too, and we can start like a network kind of a thing. So i've got all kinds of ideas about that stuff, but my head goes all over the place. Um so shoot me an email.

Let me know if you guys have any ideas. Um, let me go to the chat, real, quick and see. Uh get a snap on you'll need a mortgage but they're good, oh good! That's a good idea. Will yeah i'll look into that man um.

I did. I just stepped up and bought a mega a while back and and that's another thing too god. I can't shed spoiler alerts but that motor right now right there guys - i i hate to say this, but that motor right there - that's why i haven't made this video, yet um threw me for a loop and the mega is what made me figure it out. Okay, there's an insulation leakage in that motor, but the dang thing is so my new, so my knew that it would only happen when it rained and it only rains in california two to three times a year so and it had a horrible insulation leakage that i Would not have found if i did not have an insulation tester, so that was an interesting one and i'm i'm starting to get enlightened and have more fun, i'm starting to be inspired by the industry again, and it does happen.

I kind of got into a rut and i've been slowly climbing out of that with this video with these videos. These videos kind of gave me something new to look forward to and um sorry yeah. I lost my train of thought there for a sec, but um yeah humidity changes your readings. That's right! That's right! Jason! Exactly so! I totally lost my train of thought there for a minute um.

So i did want to talk about real, quick, um uh. In my videos, i'm gon na make it clear right now. I think i'm pretty clear with most my people, so first off i'm gon na say: we've had an influx of new people to the channel and i welcome everybody to the channel. I don't know if you're watching this or not you watch my other videos, but i welcome all the people to the channel.

But what's interesting is because i started doing occasional youtube shorts, that drove different traffic to my channel and i'm getting an influx of very dumb people too. Just plain dumb and it's like these people are all new like it just came, because my viewers have kind of been consistent for the last year, my normal viewers and then all of a sudden, i'm getting all these new commenters. And i'm like this guy's a dummy. You know um, but anyways.

Someone had made a comment and i'm gon na make it clear right now that um he he he likes my videos, but i complain too much in my my videos and i'm complaining, i'm trying to think like. I don't feel like. I complain, i don't see that i don't know, but maybe i do but um it's not complaining, i think, is what i'm realizing. I don't think he regularly watches my videos and knows who i am yet and i don't think because you know he said.

Basically, i'm complaining too much, i'm not complaining. If that's what you think, i'm just trying to make people realize that i'm the same as them. I try to put myself on a level where i think other people um are similar to me. You know, and it's like hey guys, this was a struggle for me, so i'm gon na preach about it on here you know.

So basically, what i'm saying is this is my channel and i'm going to talk about what i want and, if you don't like it, see ya, bye, felicia, whatever you know, um good riddance, i'm going to do this. The way that i want to do it. If i want to talk about mental health, because i'm thinking about it because my head's messed up, i'm going to do it and it is what it is you can move on. I i sometimes i get this idea that i'm only a technical channel, but it's not that's not the truth, because i'm trying to give an insight into me right and you know, there's a whole series that i haven't done in about two and a half years where I had interviews with my wife, and so i like to talk about how i am me and what makes me me, and you know what works for me.

That's what this channel is about. So you're hearing me troubleshoot, like i'm talking to myself. That's what i do. Every day, if i don't turn the camera on, that's how i troubleshoot i rationalize with myself.

I i verbally talk things through it's no different. When i turn on the camera, i'm a nut case. I know it. I i mean i can't express that enough.

I genuinely talk to myself and answer questions and that's how i troubleshoot so i know that's different, maybe someone else is like me. Maybe i you know so that's why i like to talk about this stuff i like to let people know who i am and why i do the way thing you know. I why i do things the way that i do them so um be nice or leave. That's right, uh, my daughters bought this.

I'm sorry did i offend you with my common sense. Is it not awesome that my children, my spawn, saw this in a store when i wasn't with them and they said mom buy that for dad like and my kids were young when they bought this? For me, too, you know i'm gon na do things my way and if you don't like it see ya, it's all good um did i see uh, let's see uh r134 a whole uh. Did you see i? I don't get your n. Your screen name intrigues me right r134, a whole like like i don't get it anyways um.

Did i see that the president said the future for energy? Is solar panels and heat pumps to power our future? I think that is a a goal and i think it's a novel goal. Do i see massive problems with that? Yes, i do. I live in one of the worst states. Well, in my opinion, one of the worst states - but i don't know - maybe there's others that are worse - where our power grid sucks.

We have too many people, we don't have enough energy, we shut down our nuclear power plants, good or bad, whatever you believe we shut them down. We took a large portion of the grid away when we did that our state struggles with power issues um and uh. When it's summertime, we have rolling blackouts, because i mean we're one of the most populated states. I think, if not the most populated states in the united states, but yet we have the worst power grid, in my opinion, so um do.

I see problems with going electric for everything i do um, but do i believe in the future of that? Do i believe in the efficiency. Yes, take away those power issues. Yes, electricity is the way we're not well again, assuming that we have renewables coming in right. We need to have renewables that are coming from the sun, whatever kind of power generation.

I really think we should go the nuclear route um, i feel, like you, know the the stuff. The problems we were having with the old technology was because it was old technology and it was either not upgradable or didn't get upgraded in time. I feel like with today's technology. Nuclear could be a very smart option, but anyways that's a whole nother thing.

Man did. I start getting all preachy on this thing. Didn't i um i'm a preacher today, uh. Would i be interested in taking supermarket work? I would love to go on supermarket calls and learn.

I would that would be amazing, but i can't take my company there. So no i'm not going to take on supermarket work, but i would love to be a part of it just to witness it and see it. One of these days, i'll hit one of my friends up or something and try to go, walk some jobs or do something. I would love to be able to take this channel to that level too.

I'd love to be able to go out there and film stuff kind of be. Like you know, micro is the dirty jobs. Kind of like that whole thing with hvac, like i'd like to start showing the things in the industry to more people, that'd, be something fun and again going back to the idea that this channel is kind of getting to that point where i need to start making Some decisions because i need to be able to focus more of my time and less of my time on my other business. So that way i can make this one grow, even more um all right, let's see what else um, let me see you can speak a length about nuclear.

Oh yeah, nuclear power. Is the sun yep um, let's see what else we got uh. Would i be? Oh yeah, i already answered that question. Uh.

Did i ever send that milwaukee swag? Yes, you did anthony. I did send that my wife dropped it at the box. Today, um i processed it. You should have got a confirmation, email with a shipping tracking data and um.

It would have came from us postal service, we just dropped it off, so it will be there in probably two days um, because i remember you were in florida. I think so um. So yes, you will get it uh. Am i still accepting applications? Yeah um? So i mentioned that i was hiring and stuff.

I haven't hired anybody, yet i've just been so busy. I haven't had the chance to go through them. So if you have a resume, you want to send me. Um hvacr videos, gmail.com uh and send me a resume and i'll add it to the list i haven't chosen.

Anybody haven't picked anybody, yet i haven't even done any interviews yet so um, let's see what else we got going on in here. Ah, will speed laska, you guys are funny. You guys are funny so um all right. Let me get to my checklist right here, see if there's anything else that i need to cross off the list.

Oh so i talked about it on the overtime show and i just realized this um. If you guys don't uh, if you guys don't already follow the hvac overtime, show: okay go to the hvac overtime, youtube channel joe. I don't know if you want to post a link to that go subscribe to the channel. You guys got to watch the show.

Okay, so um. I had made a comment that uh for the first time i ordered refrigerant off the internet and everybody i've been so reluctant to do this and i needed some r290 refrigerant. There's this internet reseller that a bunch of people have said is great. I've.

I've had multiple people in my state and from other places message me email me whatever and say they purchased refrigerant from this company. It's a lot cheaper and it's perfect. Okay, i'm not going to name the company yet, but it's probably not too hard to figure out who they are: okay, they're very concerned about the environment and they wan na. You know um anyways, so they sold me r290 refrigerant and i got it and i brought it in just to kind of show the guys on the show.

You know - and it was the first time i put the little cap on it and i i opened it and it smells like barbecue propane, like it's barbecue propane, like legit r290, that we use for refrigerant doesn't smell like anything it's unodorized and they sold me barbecue Propane by the time i paid for a 15 pound drum right, i think i bought a 15 pound and uh uh at checkout. It was like 230 dollars with shipping and all that stuff. So about 230 dollars for 15 pounds of barbecue propane yeah, i'm a dum-dum. So that was pretty funny and i i realized it on the show, so you definitely got to watch the overtime show so um.

Definitely, let's see when you're cleaning the unit from the inside. How important is it to not get the compressor wet? Um. Dyl444. I don't know what your uh, what your affiliation with the industry is, there's nothing wrong.

Um. I don't know if you're a homeowner, if you're a consumer, if you're a technician um, i don't know okay and either way it's all good uh. But what i will say is um we're not too concerned about getting the compressor wet at all. Okay, i can just kind of tell from your question.

It just seems like you might be a little bit newer and there's nothing wrong with that. I totally invite all of that, but so don't take it as i'm trying to be rude or anything like that, but yeah, it's not a big deal to get the compressor wet at all. If you do it right, obviously you don't want to soak the terminals and different things like that, but if you're cleaning it off yeah no big deal, you know it gets a little brushed off. You dry it off.

Let it dry drip dry, you know, um, don't you know they're typically made to handle water, because they're sitting under the condenser, where they're gon na get rained on so they're meant to handle a little bit so in a normal service, technician cleaning it!.
