So foreign, 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, hey. What is up, how you guys doing all or how are you all doing out there? I heard today that we can't say you guys anymore, because that's too singular so we got ta, say how's everyone doing out there all right, so uh hvacr videos live stream. Okay, i got a lot of new people here.

I know um. My name is chris. I'm an hvacr service tech here in southern california and uh i like to make these uh videos on youtube to kind of share the little bit of knowledge that i have um. You know with my youtube channel.

I do want to go into uh some transparency. You know i get a lot of comments and questions quite often of people asking uh uh who sponsors are and different things like that: okay, so um. I have two sponsors for my youtube channel they're, both amazing sponsors right spoiling and refrigeration technologies, but i can absolutely 100 percent tell everyone out there right now, those two sponsors i i specifically targeted or talked to them, because i loved their products. Okay, spoiling has always been something that i've used in refrigeration technologies.

Also, and the cool thing for me is that refrigeration technologies is a local company out here, but i just wanted to make it clear. My sponsors do not dictate anything about my channel, nor will they ever okay and the same thing goes for any other channels that i'm part of okay sponsors will never dictate that uh. We always try to find people that work with us. Okay, all right cool.

Let's get off that topic um, i will address the chat here in a little while, if you guys do have questions or things that you want me to cover in the chat, do me a favor and put them uh your comment in caps. Lock that way, i can read it and myself for the moderators um we'll get to it. Okay, now, uh! If i don't get to your question, you can feel free to keep reposting it. Unless myself, or one of the moderators tells you to stop okay, you can also send me an email at hvacrvideos gmail.com, because i'm sure there's going to be a lot of stuff that i don't get to people's questions that i don't get to feel free to send Me an email, okay, um.

Let's get this off right now, uh, it took forever. I know, and we finally did it. Okay, we released the uh hvacr tools, youtube channel, so it's simply hvacr tools on youtube. It's a little project that my friends and i are doing together, i'm going to go ahead and post a link in the chat right now for you, okay, please consider, subscribing and give us some watch time on that channel.

It'll definitely help us out. Okay, the first video that we did on that channel was on the testo uh new 550 series, manifolds the s and the i um, and we had three different reviews and each one of us liked them and didn't like them in different ways. Okay, you guys can definitely see once you go to the channel. You'll see that now we also have a little contest or giveaway or whatever you want to call it going on on the hvacr tools channel, okay, of which i just posted the link to and i'll post it again here in a little while um uh adam one Of the guys, on the show or on the channel, decided that his manifold he's gon na go ahead and give that away now to preface that it is a slightly used manifold and trust me because it came from adam.

You guys want to go ahead and wipe that down with lots of sanitary fluids and stuff. Okay, you want to make sure that thing is nice and clean now, but in all seriousness, adam just opened it up, checked it out and it's not really something that he's going to use so he's going to give away his testo 550s manifold. So there's a couple things you need to do: you need to be a subscriber of the new channel, hvacrtools and i'll post the link again right now: okay, so um, once you subscribe to the channel, you need to uh also go head over to our other social Media platforms, facebook and instagram make sure you follow those pages too okay, but on the youtube channel itself, we need you to leave a comment on two videos. Okay, you need to leave a comment on the very first video on the channel, the pants video, and then you need to leave a comment on any one of the two testo videos.

Okay, that just says hvac overtime, all right um do that and we're gon na pick a winner on the hvac overtime, show this friday and adam's going to send out his new testo 550s manifold to that person. Okay, you do have to live within the continental, united states and we'll discuss shipping and stuff with you, but so long as you're close and it's not a big deal, then we'll go ahead and ship it out to you. Okay, um! So definitely go subscribe to that channel. Uh follow us on our social media platforms.

We got a lot of new stuff coming to that channel. Again, it's called hvacr tools. Um we did the testo video. I've already got a veto, uh tech pack, mc video loaded up, because i have the small veto backpack.

So i did a little video on that and then we've all got a bunch of new tools coming. I've got a bunch of different new veto bags coming and adam just got a new blower door bill and i kind of discussing a few things. Maybe the navic vacuum pump the battery operated one also maybe doing thermal imaging cameras, because joe has one too. I have a few of them, so lots of new content coming for that channel.

Please go consider, subscribing and help us get our views and everything up on there: okay, um! What are the main okay, so uh jay gonzo asks what are the main tools needed for new technicians now i don't know if you emailed me that question too someone had emailed me a question just like that, and i kind of want to consider doing something in The future making a video or something like that, but as far as a new technician goes, i strongly strongly suggest that you contact the company that you might be going to work for and or local companies in your area and ask them all what tools they require. Technicians to bring to their company because every company is different. Some companies want you to use specific tools. Some companies don't care.

Some companies buy everything. Some don't buy anything okay. So before you go and blow your load on a bunch of uh um, you know different tools that are really expensive. You definitely want to do some research and find out.

You know what you actually need. Okay, next thing: uh, i don't want any new people out there to go, spend a crap ton of money because once you start working for someone - and this is why you want to contact someone before once, you start working for someone. You know they're going to say yeah, that tool sucks and you're going to learn too. You know you know, i've had people come to work for me, their first day of work and they've got a tool bag, all loaded up with hand tools, and it has like a hammer in it, and it has like some giant pliers and things that they'll never Need? Okay, so uh, you know you don't want to have a bunch of stuff that you don't need, but the basic basic tools that any air conditioning and or refrigeration technician is going to need is some basic hand tools.

Okay, some adjustable wrenches. Some channel locks some pipe wrenches things like that: not big giant heavy duty, pipe wrenches, but i'm talking like canipix uh, plier, pliers, rent or plier tools, or i can't remember the name of the canipix but they're like channel locks right, um, adjustable pliers. I guess you can say uh, you know a basic meter right, but even still you want to be cautious about spending a bunch of money, okay, but you also when you're, when you're looking at tools. In my opinion, the way that i go about things is, i don't ever want to buy the cheapest um and i don't always necessarily buy the most expensive, i'm usually somewhere in the middle, a little bit closer to the more expensive ones.

But i also pay attention to brands and different things like that. Okay, certain uh chain tool stores might sell you a bunch of crap. That's just going to potentially hurt you. Okay, you got to be careful buying some tools because, if they're being used and they just disintegrate in your hands - yeah it's great when you can sue someone but who's going to help you when you're blind, because something exploded in your face or something like that.

So be very cautious about that: okay, hello to everybody out there. So i saw a couple questions in the chat before uh people were asking how my shoulder my neck is. I've been doing a lot better. I've still been going to the chiropractor relieving some pressure.

Getting things calmed down, i certainly still want to go, see the normal doctor and have them do an mri and stuff like that just to see if i have any bulging discs or anything like that, but at this time right now it's definitely i'm getting more mobile. The swelling's gone down, i had a pinched nerve and i was off work for a good two weeks. It was crazy, so um, but things are going really good uh, i still haven't lost the numbness in my fingers. My fingers are still numb, especially my pointer finger.

So it's going to take some time, we're slowly getting better, but you know i'm able to move around and i've been working now for about a week and a half. So it's going good all right. What else am i missing? Um, let's see uh joshua timmons. I don't know what you're saying there bud all right uh can i describe hunting a hunting txv and what causes it well, there's a couple different things that can cause hunting in an expansion valve.

One of the most common things is an improperly mounted sensing bulb located in the wrong place. It could be a failed txv. There could be a lot of things within the valve that can cause the txv to hunt too, but the whole theory of hunting is that the valve is going to constantly open and close and open and close and open and close back and forth back and forth. So um all right, let's see what else we got going in here.

I don't know if i answered that 100, i think i felt like i got halfway through that answer and then i kind of ran out of steam. Let's see what else we got going on in here make sure i pay attention to my phone. I got a couple things on my list that i definitely want to talk about too, but um. Let's see uh, okay, well uh.

I had uh only one video the last week because i missed a video on one of the days. Just didn't really feel like uploading, so um it was the uh front. Ac is not working, so that was a york package unit. Okay, that was actually filmed back in september and uh the unit itself.

They called saying that you know one of their acs wasn't working, but when i got there i actually had one and a half acs, not working because they had a stage down on the first ac too. So, on this unit you know i kind of wanted to cover this. This unit is a piece of junk okay. It's it's got a horrible or a horrible condenser.

You know it's just completely destroyed. The unit is really old. The schematic's starting to fade just the the general shape of the unit needs a new disconnect. It's just in really bad shape.

Okay, but even knowing that, when i get to the service call, i still treat it like it's a brand new piece of equipment. I still don't just assume the customer is going to change it. You know i get all the information down. I try as much as possible to look at the big picture so that way when i'm going through it, i give the customer a big picture quote and then they can choose hey.

You know i don't have the money to do that. You know we want to try to make it last as long as possible. Okay, but i'm gon na continue to do that, every single time, okay, uh, you know - and i love being able to go back to equipment and put oem fan motors back into it too. In the situation of this, we had a a high pressure lockout code, okay, so i had to kind of make an educated decision here.

I walked up to the unit. It had a high pressure, lockout code. It was running both condenser fan motors were running, but i checked the current draw on both of them. You know, and i looked at the way that when i spun the blade it slowed down really fast, which again is from experience something to me.

That indicates a bearing that's failing in the motor. If the bearing is failing in the motor, the motor can go into a high current situation. It could shut itself down, you know, but when i was there it was working. So you got to be able to look at everything and understand the sequence of operation and how the unit works.

So that way you can potentially diagnose. So i made an educated guess that the unit had a bad condenser fan motor or that that's what was causing the unit to go off on high pressure. Now it still was running high pressures, but i was comfortable with the fact that the condenser itself was trashed. Okay, i didn't let any gas out of the unit uh on that particular time.

I didn't think that there was anything going on with it, and i've been the last person to work on that. The reason why the condenser is so trashed on that unit is because the customer used to have like an in-house maintenance guy. He wasn't even really a maintenance guy. He just worked at the location and he would send him up on the roof once a month to change all the filters and hose off all the condensers.

Well, i went up there one time when he was doing his work, and i mean he might have all taken a fork to that condenser, the way that he was hosing it and i was just completely destroying it, and so that's why they're so trashed is because Of the way he used to hose it with a high pressure stream and just bend the fins on it so um just for fun. Will i ever work on a portable ice maker um? I don't know i mean if i ever came across one. I i don't know what up sean, how you doing bud um ooh interesting sean. So you said, you've got a problem with the beacon, 2 controlled system and you want to confirm if the eev is stuck closed.

Oh that's interesting! Well, if your your uh, your coils, getting proper voltage again, i'm not super familiar with beacon 2, but i have worked on qrc, which is very similar to beacon 2.. So if your your coil is getting proper voltage on the expansion valve uh, then i would assume that you more than likely have something going on with the valve. But you can also go into the beacon settings and you can see our qrc settings and you can actually see how many steps the valve is supposedly opened right. So you can go through there and it says it's open 150 steps, but you're not getting any refrigerant flow through it.

Well then, you know that's a pretty good indication that something's going on, but it could also be the data. Cable, cable, that's going between the two another thing you could do. Let's see do i have it back here yeah i do hold on so a really cool tool to have when you're working on eevs is sporelands sma12. The sma-12 actually works with multiple eevs and you can actually modulate them opened and closed.

Now. You guys aren't going to be able to see this, but i actually have a hot gas bypass valve right here and it works just like an eev, but i'm actually opening the stem on it just by pushing up and down, and you can change it to the Proper steps per second and stuff so when you're working on a lot of eevs, the sma-12 is a good diagnostic tool to have it'll come with little plugs and stuff, so you can plug it into different valves but um all right. So i would check the coil make sure it's got the correct resistance, make sure you're getting voltage to the coil uh there's also some tools out there. I've never used them but actual magnets uh kind of similar to a solenoid magnet i've even heard people say they can use a solenoid magnet and you can actually manually open the valve by turning the stem or turning around the stem with the magnet.

You should look up some of those too it's just like an eev magnet tool. Um yeah, that's pretty much all! I have to tell you, as far as checking the steps, so look at the board, see how many steps open. It says it is see if you're getting any flow through. It use a uh eev tester like the sporlin sma 12 um check.

The connection k point make sure that the coil's got a good uh uh got good current or good resistance and good voltage going to it. So hopefully that helps you but uh have i ever worked on a car ac system. I mean i've worked on my own before i don't know a whole lot about them. The only thing i've ever done to my ac system in my car was recharge it or and or find a leak and replace an accumulator dryer um, but that's pretty much it.

I don't know anything about the the proper operation, i'm not very fluent in that car speak um. Let's see if you, oh okay, you already ordered a new valve. Okay, let's see what else we got in here um, if you replace the entire 410a charge on a condenser with new refrigerant. Do you need to add new oil, not necessarily doug? I mean it really just depends on if the oil has been contaminated, so uh 410a refrigerant uh you'll find polyester oil in the system.

Polyoast oil is polyoester oil yeah. I think that's how you say it is a very hydroscopic oil, meaning that it loves moisture. So moisture just gets stuck in it and it's pretty much impossible to get all the moisture out of the oil in a refrigeration system. So if the system has been open to atmosphere which is the outside air because of a giant leak or something like that, and it's been sitting there absorbing moisture, then you may want to consider changing the oil now, if you um, if you uh, are just doing A repair because of a failed compressor because of a stuck txv or something like that.

Well, um, you know, who knows, then you can probably save the the oil, so you shouldn't have to, though i mean most refrigeration stuff, that i work on you get by with a lot now. There's some repercussions to having contaminated oils can lead to premature compressor failure. It can lead to um system contamination issues and stuff, like that uh plating on the the compressor parts, the copper plating which can slow down, bearings and stuff like that, so um. Let me see what else we got in here uh.

I said it in the beginning. I'm going to say it again, because we have i'm going to keep saying this a few times, so everybody gets an opportunity so um we released the new uh video on the hvacr tools, youtube channel myself and my friends are doing together. I'm gon na post a link in the chat again right now uh we released the testo 550 series video, so we looked at the testo 550s and the testo 550i, and we did a video now in the future. You're, probably not going to see two videos like that, we were kind of feeling out what was going to work for us.

Are we going to do joint videos so we're still trying to work out the kinks, but we never really planned on having two different videos for the testo thing, but it's just kind of how it worked out, but anyways. Please go give us some support on that channel. Subscribe share it with anybody that you guys know help the channel grow. Our goal is to be able.

I mean i can absolutely guarantee you. This isn't going to happen today and it's going to be a long time before, but our goal uh potential goal my goal. I shouldn't say hour because i kind of discussed this with everybody, but my goal. But again it's a community channel between the three of us or four of us.

So it's not just my decision, but my goal is to be 100 self-funded on that channel. Now, that's not going to happen in the beginning, meaning that we're probably going to have to take on sponsors to help, but in the future. I would love to get to a point where we're self-funded on that channel, to where we do not have to have uh any advertisers and or sponsors uh. But you know, that's that's a far ways away because it's kind of expensive to go out and buy all kinds of tools.

So we're definitely going to have to bring on sponsors and partners to help us in the beginning and work our way through it. And then maybe someday in the future, we become a fully self-funded channel, we'll see. Okay, that's! That would be like an ideal dream, but we want to give honest reviews on that channel. Just honest tool: reviews okay, so we got a really cool promotion that uh the testo manifolds.

Everybody got one: okay, as part of the channel start and adam said he's not even gon na use his because he doesn't need another manifold right now, so he's actually gon na give his manifold away. It's slightly used and, like i said in the beginning, you guys may want to sanitize it with uh antibacterial sanitizers, because you never know what adam's into so. You want to be cautious about that, but um you definitely want to enter this contest. Okay.

So, in order to enter the contest, what you need to do is you need to be subscribed to the youtube channel, follow our social media platforms, hvacrtools on instagram and facebook, okay, it's a page and a profile on facebook or page on instagram and whatever you know. What it is so follow us on social media, instagram and facebook subscribe to the youtube channel. Hvacrtools. Okay, um leave two comments that say: hvac overtime, one on the pants review, video and one on either one of the tools.

Videos, okay, do that, and then this friday uh on the hvac overtime, show we're gon na pick a winner uh. We do want you to live in the continental, united states, um and uh as long as it's nothing crazy, we'll cover the shipping, but we'll discuss that after everything else is done. Okay, so adam does have the 550s manifold and again he's going to be giving it away on friday, but you need to follow those steps so subscribe to the new hvacr tools. Channel uh follow our social medias on facebook and instagram.

Hvacrtools leave a comment on two of the videos on the channel, the pants video and any one of the testo videos, okay and then we'll we'll pick a name on friday. All right. Let's see what else, how much of a walk-in freezer's drain needs to have the heater on it nathan uh? Ideally, you want the defraud or the drain line heater on every inch of the walk-in freezer drain or what i mean by inches. Is you do a pipe wrap right? You wrap it around there and, depending on the temperature and the size of the pipe, and you know the pitch that you get on it.

You need to bring the wraps closer together or further apart, but you need it to be wrapped around the entire drain line. Okay, so they make cut to fit heaters. You wrap it around. You insulate it a little trick.

If you guys don't already do this, because i i used to struggle with this when you're doing drain lines, if you have a standard, three-quarter inch drain line, okay coming out of your walk-in freezer, what you do is you buy the cut to fit pipe wrap stuff. You wrap it around there. Okay, uh sean. Thank you so much for that super chat bud.

That is amazing. Thank you. I really appreciate it. Man um, so you wrap that heater all around it and then you put inch and an eighth by three quarter: wall insulation over the heater and the drain line, and it will slide right over it.

So if you have a three quarter or yeah three quarter inch drain line, you wrap a heater around it and then slide inch and eight id insulation over it, but make sure you get the three quarter or the one inch wall on the insulation and that will Work amazing, but you need to have it touching as much of the drain line as possible to be safe. Okay, all right, let's see what else we got going on in here. What's with the continental us, alaska has the same postal service as that yeah. You know what i you're right: alaska, when i say continental you yeah you're right, i shouldn't have said continental, we'll we'll take care of you bud.

Just just trust me all right, um, let's see what else uh. What else do we have? Do? I ever work on co2 racks at all no luke. I do not uh very interesting, though we had a great great conversation on the friday uh hvac overtime show with uh trevor matthews from emerson and or copeland and uh. We were talking about a bunch of co2 stuff and it was actually fascinating because i don't know very much about co2 and he was kind of explaining to us some of the stuff.

So definitely go back and listen to last friday's hvac overtime show it's a great show. We had a great conversation and a great time, and you know what's interesting too guys and unfortunately we can't. We can't do this, but i i just want to say this so that way you guys can be jealous at the end, because nobody will ever get to hear this stuff is after the overtime show, are some of the best conversations each guest that we've had on The hvac overtime show on friday, whenever the show is over. They usually stick on the show for a half hour to an hour, after just talking of course, stuff that we can't record because everybody's just having a good conversation, uh so yeah.

That was just there to make you guys a little jealous because, unfortunately, none of you will ever be able to hear that conversation or those conversations all right um. Thank you greg. I really appreciate that bud. That's that's a very uh tmi information that i didn't need to know: greg's, taking a dump on the toilet right now, all right uh.

Is it worth getting digital's as a new technician, j, gonzo yeah! I think digital gauges are a great thing for a new technician. Okay, so, but you need to understand the principles of how digital gauges work. Now in the past we used to say you know you need to learn on analogs. I don't know if that's quite true anymore, because the accuracy of digitals and what you're missing out by using analog that you're not getting from a digital gauge, is kind of a big deal.

Now, of course, you can do everything with analog gauges and special thermometers and pt charts and all that stuff, but for the the 15 minutes you're going to spend uh playing with the pt charts and conversions and calculations and stuff, your digital gauges have done 10. 000 calculations over and over and over again, because they're constantly sampling every single. Second, in fact, one thing that you're going to realize, especially for someone like me, coming from a non-digital era to the digital era, is that you know the concept of checking for evaporator, superheat on a running system, adjusting expansion valves and things like that. Even checking uh system charges when you would put analog gauges on there and you would take your digital thermometer and you'd, set it outside and you'd.

Look and you'd say, or you put it on the pipe or whatever, and you take that measurement and then you'd sit down and write it down. And then you look back at the gauges and the gauges have moved well, since the you know the the 30 seconds that it took you to do that calculation. The super you know in small increments has changed multiple times. Okay, so digital gauges will help you to see real time stuff and you can actually see systems operating.

So i strongly encourage digital gauges, but i don't want you to break the bank and i want you to be practical about what you purchase. I also want you to do research, okay, i'm not going to name them, but there's some digital gauges out there that you are absolutely wasting your money on um. You know they're just junk. Okay, there's also a lot of really good digital manifolds, such as the field piece products and testo products and the sporelin smart probes, and you know, there's several different: smart probe manufacturers.

They make high quality stuff, but then there's some really bad stuff out there too. So i'd hate for people to go waste their money on these really fancy digital things that are junk. So you definitely want to talk to someone get people's opinions on what they like, and your friends and stuff like that before you go, and you know, spend all your money on that all right. Let's see what else yeah, please guys hit the thumbs up button.

It really helps out the stream, it's crazy when you see the numbers, there's 303 people watching and we only have 113 likes. So please just do that. It's really simple! If you guys are on your phone and you're, watching the youtube channel chat right now. You just hit the back button, you hit live chat or you hit the back button and you hit the thumbs up button.

Okay, if you're watching on a tv, you can even do it on a tv by playing with the menu you can go down and hit the thumbs up button. It's a super easy process once you figure it out, so all right, let me see what else we got um. What am i seeing all right? I don't see anything in there um all right. I wanted to talk about um electric defrost, so i had a few questions on electric defrost when it pertains to walk-in, freezers, okay - and this is also going to lead into a talk about smart evaporators, uh, smart defrost, that kind of stuff okay.

So the concept of electric defrosters is that you know, and we have hot gas too, but we're just covering electric right now. So when it comes to electric defrost, you typically have strip heaters, they're mounted in multiple spots in the evaporator coil and the purpose of them. There is to quickly defrost the system all right on a standard refrigerator. The the temperatures will typically get above freezing okay on a standard refrigeration equipment, so they can simply shut off the compressor for a short period of time, usually about 15 minutes and just the air inside the box that is above freezing running across the evaporator coils is Going to defrost the system, okay melt, any frost buildup that can happen on the coil, but on a low temperature system.

The box temp never gets above freezing in a perfect world, so we need electric defrost, okay or supplemental defrost hot gas. You know, but electric is one we're talking about right now, so electric defrost, you have something that initiates the defrost cycle. Usually a defrost clock sends power to the strip heaters warms up the coil. Now we will typically do this on older conventional systems on a basic refrigeration system or freezer system you're going to do it four times a day at a minimum for somewhere to you know anywhere from 30 to 45 minutes and you'll have some sort of fail safe.

In there, so that way, if the coil accidentally gets too hot or it's in defrost for too long, the failsafe temperature control device is going to click it out of defrost, we'll call it a a limit switch and the system will stop defrosting. Okay, so we usually use a time clock, it's automatic it does it four times a day, no matter what, but the problem with that - and i understand the problem is that electricity is expensive. Energy is being wasted in a defrost because it's not always necessarily needing to defrost for as long okay. So today we have new technology called smart, defroster, smart, evaporators, okay, they have circuit boards and little microprocessors in them and they have tons of sensors and they have algorithms and they follow certain things.

If the temperature of the coil gets this much above the temperature of the air for this much time, blah blah blah blah, it has all kinds of algorithms. Okay. But in my experience in the stuff that i work on in the restaurant industry, which is high volume, opening and closing doors, we have a lot of issues with smart defrost, okay majority of the time i usually like to give it one shot. But majority of the time on new installer i mean on on equipment service, i will take it out of smart defrost and put it back in the normal timed defrost.

Now many of the manufacturers out there have the ability to do this. If you're working on heat craft equipment, you can go in there and you can change it to smart, defrost and or time defrost. So the smart defrost it'll typically look at sensors and have some logic built into it and it'll say: hey. You know what the coil temperatures doesn't meet the threshold for going into defrost, so it'll actually just skip a defrost completely, which sometimes will work.

Fine, okay, but then there's other times when the customers leave the doors open. When you know they bring hot product in there too much and different things like that, where the box might ice up and then i've noticed that when it does ice up, the smart defrost doesn't always necessarily remove all the ice and it becomes a problem. So i have gotten into a habit of after usually the the first service call on it. I will take it out of smart defrost, put it back into time, defrost, because it's true and tested yes, it does waste a little more energy, but it works.

Sometimes you just need that failsafe to be there, so that is why you will see me in some of my videos: do that: okay, um! Let me see how is it, and this is a question i get all the time, guys um. How is it that i spend so much time on my service calls and how many service calls do i get done a day? I can't give you that answer. As far as how many i get done a day, because i only get to get done as many as i can, you know, even in the middle of the summer time, when we're crazy busy of course there's times that we have to run around putting fires out And just triage the situation, get it bandaged up and come back and fix it later. But majority of the time i and all of my employees will spend as much time as needed on the job, with the customer's permission to get the job done adequately for whatever we need.

Okay, the customer may not want us in their cooks line for so much time, so we got to do whatever we got to do to get it operating then we come back and finish it another day, but i don't have a set time, nor do my employees And i can in fact tell you right now that every one of my employees out there i have to get them to stay longer, meaning that they constantly will go out there and be like all right, everything's good and i'm like hey. Did you check this? Did you check that? Did you do this? Did you do that they're like well? No, and i go, do it spend more time because i want to be thorough. Call backs to me: are the end of the world? Every callback is a little bit of your business. Going down the drain: okay, every callback is lost, faith in the technician and or the company, it's the customer being dissatisfied.

So with the customer in the loop and with the customer's permission, i always want to spend time the proper needed time. You know explaining everything to them and showing them, and you know giving them the big picture, diagnosis. Okay, so do i have a specified time that i spend on every call? No, i mean i'm sure you can figure out an average if you go and look at all my service calls, but i mean every call is different, so i'm going to spend as much time as i need now. I run my own business.

This is how i choose to do things. I do realize that working for other companies may not let you do that, so be it. You got to figure out what's right for you and your own okay and if, if you know you're having a hard time because they don't ever, let you fix it, i don't know, but also on the flip side. Sometimes the customers don't want things to be fixed.

Okay, so remember that too sometimes the customers just want band-aids and they just want things just half-ass working. You know if that's what they want, i'm still going to give them a big picture, diagnosis and a big picture quote and they're going to choose whatever they want to do so all right. Let's get to the chat and see what i'm missing here, um. Ah, so dave johnson asks does the new 2021 walk-in regulations require all this fancy, defrost and ecm motors on new installs, so i'm actually working on something but yes uh.

So there's a new uh standard that is in its infancy right now, it's just being born and it's called awef awef annual walk-in energy efficiency, something rather i don't know what the whatever it stands for. It's just a you know whatever another one of these four-letter words but um okay. So what it is is there's an energy mandate so right now, it's still in its infancy. Basically, that the government just came in and said you need to have these standards.

You know, and it's really simple, there's no enforcement right now other than maybe your your planning department when you pull permits or something like that, asking to make sure it's awef certified or whatever, but um energy efficiency is the biggest thing. So it has to be energy. Efficient, it has to meet certain energy usage guidelines, okay, uh and so the way that they're doing that in most of the refrigeration systems is they're. Dropping the condensing temperature, okay, which is going to drop um the pressures in the system uh in the winter time.

Essentially, okay, so they're flooding the condenser at much lower temperatures to try to maintain head pressure or floating the head pressure. If you want to call it and uh that's one of the common ways: uh defrost strategies, uh ecm motors, is another way so they're integrating more electrically efficient, stuff uh. It's it's only a matter of time. I mean think about it.

The the comfort cooling side has the seer ratings and you know the the the seer rating minimums that are all over the place. I think we're in like 14 sierra minimum here in california. I think it's been. I don't do rezzy so um, but it's it's inevitable.

That it was going to come to the refrigeration side, but that's basically what it is so energy standards uh. I don't know about smart defrost. I think smart defrost might be part of that, but they all have fail safes, because all the manufacturers know that each smart defrost system has an issue so um time. Defrost is you know the most reliable in my opinion, so all right, let's see what else we got in here um.

What was the worst design exhaust fan? I've come across john deere fans, so um, i i don't know if i've shown it on video. It's the one that i said. No, i don't know, i don't remember what the title was, but uh it's a captive air fan and i had to show the airbags trying to get the wheel apart. The customer had me change the exhaust fan, so there's nothing wrong with the fan.

The fan itself does an amazing job, but what they did was when they built this particular restaurant. It was an existing building and they used the existing dock ductwork for the exhaust fans because they use the existing hood. So they put a new fan on the roof. They use the same.

The old roof curb, but the ductwork uh is too small for the exhaust requirements. Basically, so it's just a poorly designed system and uh also when it gets filled up with grease like because they do have grease in those ducts uh. They have hood cleaners that go in and clean it, but you know when it does get filled up with grease and they wash it out. They did a crappy job welding, the ductwork from the day one, so it actually leaks from the seams.

It's like a whole mess, it's just a horribly designed system, but uh that'd probably be the worst. I know that doesn't really make probably sound that great coming across video, but all right, let me get to my list here - alex asked why and when would you use a helicopter to lift equipment onto the roof? So i appreciate everybody that watches this channel. Obviously it sounds like alex is not an hvac person and that's fine. I encourage everybody because i try to share the little bit of knowledge.

I have with everybody. Okay, so um helicopters are typically used when it's not a smart move to use a crane. Okay, we will typically use a crane, but sometimes it could be uh easier, faster and cheaper to use a helicopter and get the job done in a matter of you know, hour or less than a crane that has to set up and change. So, there's nothing worse than a giant building.

You can usually get it done with a crane, but the crane will be a mobile crane. It will have to move from point to point to point and every time it does that could be hours in between. So in that situation, yes, helicopter lifts are very expensive. I personally have never done one, but i know they're extremely expensive and uh, but if you can get them done in no time, then you know knock it out, so that you'll typically see helicopters on that.

Also in one of my videos, he also asked why the top of the ac was painted black um. That was one of my restaurants. It's a train package unit. It's just to be aesthetically pleasing a lot of the times.

We got a lot of these yuppy cities out here in california and um. They want to control everything and they want the building to look perfect and even from a mile away. They don't want to see the rooftop equipment, it's silly requirements, so the restaurants will often paint them to kind of make it look like it's part of the building. You know so yeah, it's just for aesthetics.

Basically, all right, um you've had helicopter lifts for large is right on, but yeah i've never been part of one of those i quoted a helicopter lift. I think i've told this story before, but i'll tell it again. Uh many many years ago there was a new restaurant that we, it was a chain that we were already working for, but they had a new location that they needed our help with. So we went out there and they needed two new air conditioners on the roof.

It was at a shopping, mall and uh. It was one of those situations where a normal crane wasn't and the size of the crane was going to be giant to be able to get to where it needed to so we quoted a helicopter lift. No, i didn't get the job, but we did quote us two new uh units on the roof, a helicopter lift and all this different stuff, and it was a huge quote and we ended up not getting the job and a couple months later, i ran into the Facilities director - and he was telling me the story about what happened so they had another company come in that was under. I think they said they.

They basically were like a thousand dollars less than us, or so it was minuscule the amount that they were less than us, but they chose their quote because it was cheaper and that company did a helicopter lift without pulling permits. Okay, so permits yeah, i'm not going to lie and say i've never done a job without pulling a permit. I have, but when you do that, you don't use a giant helicopter that people can see from everywhere, and also can i tell you that this location was in the flight path of los angeles international airport, so that helicopter you know, was working with federal too. You know getting permission to do this, lift and all this stuff and the contractor did not pull a permit on the job and they got popped for it and the restaurant itself.

The contractor got fines too, but i was told that the restaurant itself got a ten thousand dollar fine for that and they had to build to bring the building up to code, pull the proper permits and do the other stuff. But on top of everything they had a ten thousand dollar fine to the restaurant and they didn't go with me because i was a thousand dollars more than the other company, so yeah. That was an interesting one but yeah. That was the only one that i was potentially going to become part of a helicopter lift but other than that i've never done one so um.

Let me see what else we got in here. Will my symposium class cross over to the resi side or stay on the commercial reefer um jessica, my my class uh, so the the top? Let's step back this thursday, i am going to be a guest speaker at brian orr's event. I'm going to be doing a virtual session. I will not be there in person, it is the hvacr school sympo training symposium go to hvac school hvacrschool.com and uh.

You can see the event information, they have virtual tickets. If you want so you don't actually have to go in person, but i am doing a presentation. It's going to be about an hour, long presentation, uh, it's going to go along the same concept that i always preach: big picture diagnoses and i'm going to show some examples and how things can you know the title of the talk is going to be four common: Big picture repair things that were missed or something like that, but will it go into residential side well jessica? My videos that i'm going to be showing are not going to go into residential side. The videos that i'm going to be showing are going to be commercial side, but i promise you 100 percent, that my talk will transition.

It will cover the residential side. It will totally make sense. The whole point i'm trying to make by showing examples is totally going to bleed over into residential it's going to bleed over into anything, so that will be on thursday, jessica, so yeah there. It is um guys if you haven't already registered for brian's event.

Trust me hvacrschool.com, you can do online virtual or you can do in person, but online virtual and you're gon na have access to the videos that he makes online and stuff like that for like a while after the presentation. So it's not like you just got ta watch it that day, you're gon na have access. After so for the the very small amount that he's charging for tickets, even in person tickets are totally worth it, but if you can't make it in person, trust me do the digital okay! You want to do that because it's going to be great great stuff on there all right, let's see what else uh, why do i make p-trap on refrigerant lines on a walk-in chad? So it's all about refrigerant, velocity chad, because, as the refrigeration lines get longer and longer, it gets harder and harder to push and pull refrigerant through them. Okay, the velocity or the speed of the refrigerant slows down and or speeds up at different times, depending on the refrigerant line sizing.

So, along with refrigerant velocity comes another thing: refrigerant carries oil when it moves. Okay, so oftentimes the oil can leave the compressor and get trapped somewhere else in the system, typically in the evaporator coil. Okay, this will commonly happen when you have a compressor or condensing unit up above the evaporator down below okay, so with the oil traveling with the refrigerant that oil can get stuck in the evaporator coil and oftentimes, once it gets going through the evaporative coil. There's a pressure drop right.

You've got liquid refrigerant coming down through the liquid line and then there's a huge pressure drop 100. Something psi difference. So then the refrigerant slows way down and it runs to the evaporator coil. So that way, it can absorb the heat and discharge that heat outside.

Well, when that refrigerant pressure drop happens after the expansion valve, the refrigerant slows down starts absorbing the heat, and some of those oil droplets can get left in the evaporator. What we will often do is add a suction line, p trap on the suction line coming out of the evaporator and what it will do is it will actually speed up the refrigerant when it does that little whoosh through there, and the theory is - is that it's Going to grab those particles and help to carry them back up to the compressor. Now it's not just a p-trap at the compress or at the evaporator. Sometimes you may need to put p traps in multiple places on the refrigeration lines too, because you know it may have a really long line set or something like that, and the same theory is that as the lines get longer and longer, the velocity of the refrigerant Potentially slows down because you know the the it's harder to push and pull that refrigerant through the lines.

Okay, so hopefully that answers why we use a p-trap. It's simply there to increase the velocity of the refrigerant in hopes that it grabs the oil droplets and helps to get them back up onto the roof uh. Hopefully i didn't butcher that answer um peter's smart. I can use my drone for my next lift.

So, yes, i did get a drone. Unfortunately, i can't use it for any youtube videos. Until i get around to taking my section 107 faa drone pilots license something or other which i don't know if i'm ever gon na do. The drone honestly is supe something just fun for me to do on the weekends like this weekend i went to in my area.

I went up to mount baldy uh mount baldy village and i flew my drone like getting some cool shots of the mountains and then on sunday, my wife and i and my kids went up to lake arrowhead, which is another resort town up in my area and Flew the drone around up there getting some cool mountain shots too. So it's just something fun for me to do um i mean it sounds kind of cool using it in a video. But honestly, if you think about it, my customers might freak out a little bit as if i'm climbing, on the roof. There's a freaking drone following me and they're like what the hell are you doing up there, you know, even though it sounds like it'd make for a cool video but um all right.

Let's see what else we got in here, i'm going to mark some things off. My list so that way, i know that i already talked about them already covered that question right there. This is a common question. I get a lot too, it's not necessarily hvec related, but i want to go into this um first off.

Do i think that youtube is too crowded? No, i do not. Do i encourage all you guys to start youtube channels, sure uh, the cool thing about youtube is everybody can choose whether or not they want to watch your content? If you have knowledge in anything, i highly encourage everyone to share the knowledge that they have uh. There was a generational thing that people used to think they had to covet their knowledge and not share it because they felt like they were going to make the i'm. Assuming that they felt like they were going to make themselves obsolete guys, i am not going to be obsolete and neither are you share your knowledge.

Okay, we have such a need for good technicians and, if you're, a technician that has knowledge to share. That means that you probably have experience. That means that you're, probably an asset so share your knowledge, make a youtube channel start a podcast, do whatever. Okay anything you can um, so uh just be honest and informative and you'll probably find someone to watch your stuff.

Now, when it comes to youtube, i'm gon na kind of segue a couple questions in here when it comes to youtube, how do you get past being afraid, um? What, if you don't want to put yourself out there, what, if you're afraid to put yourself out there, look when you create a youtube channel, trust me from experience. It doesn't grow overnight. It does not explode. The first video you post on youtube is going to get absolutely no views for a very long time unless you share it with someone, you tell them about your channel because there is so many channels out there.

So it's going to take time right. So what i mean by that is this, don't be afraid to put a video up baby steps. Put a video up, get one or two views get feedback. Take the video down redo it do whatever, but don't be worried about putting yourself out there, because it's gon na take time to even build your channel up.

Anyways. Okay, it took me a long time to get this channel to where it is three something years and then i'm starting other channels, the hvac, our tools channel and that's on the ground floor. Not even you know, barely that's, not even monetized, there's not even enough on there right now, so it's gon na take time all right, so um. What was the other one, so what studio equipment do i use is the other question that kind of segues into that.

So i use a lot of road products now i have a very capable computer that has all the processing power and all that fancy stuff that i need. I have a triple monitor set up right here. You don't have to have all that, though. Okay, basically, to start a channel um, what you need to have is a computer, a usb microphone, good internet speed and you can hit the ground running.

Okay, you can build up to the setup that i have and mine's, not even that fancy my monitors. I have a triple monitor, set up, they're, cheap monitors, it's nothing fancy! I can't watch movies on them. They get all glitchy and crap, but i use rode products. I have a rode procaster microphone and a road caster pro mixing board.

Those are the two audio things that i use to make things better and then a camera. You know your your smartphone, you can do a youtube video with your smartphone um. You know you don't got to go, buy the fanciest stuff in the world. Okay, so hopefully that makes sense uh do i ever get recognized.

Do my neighbors know that i do knock it off? That was great, so knock it off says. Do i ever get recognized and do my neighbors know that i do hvac internet porn uh?.
