Hey guys, how's everybody doing out there still trying to get a little used to this new setup. I got going on, hopefully I'm working all the kinks out and it's not too horrible happy New Year to everybody all right. So, though, the most recent video that I uploaded today, I'm gon na kind of start off light right now guys to try to let a few more people file in okay. So the most recent video that I uploaded today had the where I was talking about the duct detector.

I mean the original service call was a thermostat. That was bad, but I think the more important part was when I talked about knowing the fire systems and how the duct detector can affect the fire system, and I think it's a very important thing to understand how to put fire alarms on test. It's something that we at my company have to do all the time. We make sure that our systems - you know before we work on an r2 unit that we hold on just one second yeah yeah.

We make sure that um, you know we always call the fire alarm before we have the manager call the fire alarm. Company put the system on test, you know usually for like six hours is kind of, like my rule of thumb and then it'll automatically go off a test after six hours. You know, so you can just put a time limit on it. So it's really important to understand because, like I mentioned in this video and a previous video, the last thing you want to do is get the fire department to show up now most systems.

If you shut off an r2 unit, it's not gon na call. The fire department - it's just gon na - put the system into a trouble condition, but there has been the instance where I was working at a shopping mall and I did put the system for whatever reason it was wired wrong and it put it into a fire condition And it was not good okay, so it's just always safe. You know to ask the management before you go and shut off our tu units. You know if they need to put the system on test and have them do so.

Okay, so it'll save you guys some headaches and possibly eliminate um some problems. You know so guys that are just filing in right. Now you haven't missed anything yet just kind of going over the last video that I was talking about so again. The people that are just filing in happy New Year to everybody - I hope you guys - are gon na - be safe tonight, don't drink and drive.

You know all that good stuff, so I am gon na answer some questions. I've got some email questions I'm gon na address. I am gon na show you guys a short little video that I have to kind of talk about what we were just talking about with the duck detectors and the trouble conditions. So I'm kind of monitoring the chat to to make sure everything's good you guys here and everything, okay, everything coming through good, okay, cool right on all right.

So what I want to do is I want to go ahead and transition on over into this video again. We're talking about duck detectors and especially the trouble contacts in a duck detector, which is what could trigger the trouble condition in the fire alarm when you shut off the unit. Okay, so yeah Alexandre someone pulled out automatics and started shooting you know in my area, where I'm at I'm close to a pretty bad neighborhood and yeah. We could run into some problems with that kind of stuff.

So anyway, so I'm gon na go ahead and transition on over to those video guys and then I'll come back right after the video and then we'll talk a little bit more okay. So this isn't a video that I've released or anything like that. So you guys aren't what this is something new that you guys are gon na watch so give me just a second and try to figure out how to transition this over, and we will get this started right about now. Okay, so on my trainer board here, I've got a duck smoke detector set up and I have it set up so that we can simulate trouble conditions or alarm conditions, and I just want to explain the difference.

Okay, the trouble condition is an instance where, depending on the detector, this particular detector, I can set it up to initiate a trouble condition if you were to remove this cover. So let's say that someone was doing some work on the duck detector and they left the cover off. It would simulate, or it would initiate a trouble condition which would the alarm company that there's something wrong, because if he left the cover of this detector off theoretically, it wouldn't sense smoke properly. That way that this thing works is sorry guys bear with me here still trying to get used to this.

So hang on just one second, I apologize about that. I apologize guys give me just one second I'll get this right. I promise. So let me figure this out real, quick, okay turn on transmission, that this cover makes a seal and forces air from one side once that guy's, I'm sorry technical difficulties bear with me.

I apologize guys here, okay, so on my trainer board here, I've got a duck, smoke detector set up and I have it set up so that we can simulate trouble conditions or alarm conditions, and I just want to explain the difference. Okay, the trouble condition is an instance where, depending on the detector, this I'm epically failing at this guy's. I thought I had this all figured out and it is not working out the way that okay, so on my trainer board here, I've got a duck. So it's not going to full screen for you guys right.

I apologize guys. So sorry, one more! Second, I will get this. I promise. Okay, give me one second here, let me duck smoke detector set up one more! I'm really really! Sorry guys.

I thought I had this figured out and it is being a pain in my ass right now, so I'm gon na get this, though so just one second here so anyways, I'm gon na talk, while I'm playing with this right now. So that way, I'm not wasting you guys this time. So, on the duck detectors, you know what what I'm going to be going over is the trouble conditions that you run into on the duck detectors when kind of like what I'll reiterate again when you're walking up to an r2 unit. What you want to do is you want to let the fire alarm company know that you're gon na be working on the r2 unit.

Let the manager know they'll, usually call the fire alarm company and let them know what's going on and then we can. We can then that way when you guys power down the unit, you won't get a trouble condition here so and, as I'm still trying to figure this out, bear with me here, I'm probably gon na lose half of you guys, but I will work this out. Alright, okay, so on my trainer board here, I've got yeah. This is just not working out the way that I wanted to.

Well, that's just not gon na work out um. Are you guys? You guys don't see any video at all huh. You guys just hear audio right yeah. That's that's just what I thought yeah! That's that's what I'm having a problem with this, getting the big video to pop up on the screen so, and that is why it's being a pain in the ass for me.

So let me try it one more thing here: not that not that, let's try that, let me go ahead and try this, and this might work better. Let me try this last thing here and see if this works. If this doesn't work, we'll just have to figure something else out got a duck smoke detector set up, and I have it set up so that we can simulate trouble conditions or alarm conditions, and I just want to explain the difference. Okay, the trouble condition is an instance where, depending on the detector, this particular detector, I can set it up to initiate a trouble condition if you were to remove this cover.

So let's say that someone was doing some work on the duck detector and they left the cover off. It would simulate, or it would initiate a trouble condition which would tell the well then that's just gon na be an epic fail, and I'm just gon na have to make that a normal video. Then I apologize guys, that's what I was hoping to do and of course it's not gon na work out for me. So it's all good, we'll move on to the next thing.

So, as you guys, can I'm gon na go ahead and pull up my webcam, so you guys can see what I'm talking about right here turn off my display capture transition, my webcam over okay. There we go all right yeah, it sorry guys I'm having a hard time getting the picture to pop up, but you can see the trainer board. I have behind me. I've used that before in the past and explain the duck detector situation.

So what I will do is what I'm trying to show right now: I'll release it as a video tonight. So it'll pop up, you guys, can watch it. It'll just be a short one that you guys can watch at any given time. Okay, but I'm gon na go ahead and talk a little bit about it and explain what we're talking about so.

I've already talked about the duck: detectors, okay and there's a way inside the duck detector that we can use the trouble contact or the Supervisory contact inside the duck detector, and by putting a resistor in the circuit, we can simulate a trouble condition. So when the fire alarm company is looking for their control wiring going to the duck detector. Excuse me they're monitoring, two wires coming to that duck detector and only two okay, so they basically are looking for a direct short to tell them that there is a fire condition. Okay and if there is a fire condition, there'll be the direct Shore and then it'll usually set off the audible, strobe alarms and all that good stuff.

Okay, but the other thing we need to be able to do is we need to be able to prove that the fire alarm circuit is still good, okay, so, by proving the circuit, what I mean is what happens if someone's working up in the attic and they Sever the alarm wires: okay, if they sever the alarm wires to the duct detector and they don't create a direct short the fire alarm company's, never going to know right. Theoretically, you know they they would just see. You know no alarm at all and there could be a fire condition in that rtu unit and it wouldn't alert the fire alarm company. Now, if you know the restaurant was occupied, then obviously they'd call 9-1-1.

But you know the whole point of the duct detectors is to slow a fire down. You know it's never gon na eliminate a fire, but it's usually gon na turn off the r2u unit and slow it down. Essentially, okay. So what we would do is by placing a resistor now it can change from alarm panel to alarm panel, but sometimes it's a 10k ohm resistor, okay and it'll go across the alarm circuit and it just proves that the circuit is there.

So the alarm, the the resistor - is not enough to trigger a direct short, but it's enough to show that 10k ohm. So the alarm panel is looking and it sees that resistor at all times. Okay, so if we wire that resistor. So basically, if we take the alarm contact of which you'll see in this video, when I upload it, if we take the alarm contact, which is a normally open contact and we wire it into the supervisory contact, the supervisory contact I'll explain that in a second.

But if we wire it into the supervisory contact, then, if there's a problem with the duct detector, it would make the resistor disappear from the circuit and the alarm company would know that. There's a trouble condition, but not necessarily a fire. Okay. So usually, if there's a trouble condition, they will call and verify hey.

Let the manager know hey. You know, we see a trouble condition your rtu unit, something's going on, which can be helpful because I made a funny joke inside the video. Is that if you have a smart crackhead, that's up there, stealing the copper on the unit? They would shut off the unit right because they don't want to get electrocuted well when they shut off the unit. If we have that trouble contact wired in the way that I'll show in the video, then it would send that silent signal to the alarm company to let them know, there's a trouble condition.

Okay, now that resistor also does something in that. If one of the wires gets severed to the alarm panel, that resistor would also disappear from the circuit at the same time. Okay, so then it would let the alarm company know hey, there's a problem now. The important thing to understand is that the alarm company typically doesn't know if there's a problem with the rtu unit, they don't know if a wires been severed.

They just see a trouble condition is all that they see. Okay, so that trouble condition. Would you know they would they would call and verify? So if one of those crackheads was up on the roof and he was a smart crackhead, you know and shut off the unit, then maybe the alarm company would notify the general manager. This is the it just depends on the alarm company and the protocols they have set up, but in my area, they'll usually call the general manager in the middle of the night, especially if it's a bad area, they'll call and say hey.

We have a trouble condition with an RTO unit and sometimes the general manager. If it's a real bad area will say, hey dispatch, PD and have them look into it. You know. So that's something to understand.

Usually what happens is most most of the duct detectors. In my area are actually powered by the rtu unit, so your 24 volt power coming from the rtu unit is powering the duct detector. So if that duct detector loses power by you shutting off the r2 unit, then the trouble contact is gon na open and that resistor would also disappear. So that's usually what happens when you power down a unit and then you get you know you don't have to you know the alarm company will call or something like that.

Okay, so it's important to understand how those duct detectors work again. I wish I had my video to show and visualize with you guys, but one of the really tricky things on the duct detectors is knowing and the most confusing thing for me is the Supervisory or the trouble contact. Just remember: it's wired backwards. Okay and when I say that let's say they caught, the Supervisory contact has a common, a normally closed and a normally open.

Okay, the common, normally open, will be closed in a non trouble condition. Okay, so what's written on, the contact only happens in a trouble condition. So if it says common and normally closed, it's only normally closed when it's in a trouble condition. Okay, now all the other contacts on the detector.

Oh, thank you very much, Mike nine, five, nine. I really appreciate it now. If you sorry, I lost my train of thought there right there, but but so yeah, it's important to understand that trouble and or supervisory relay is backwards. Okay, but then all the other contacts, the auxilary, a the auxilary bees.

Those are just standard contacts, so you know there's nothing backwards about those all right. That's one of the biggest things when I was first wiring up a duck detector that we ran into is. We thought we had bad duck detector after bad duck detector and that actually wasn't the case. It was just that the Supervisory contact was backwards.

Okay, if you read the installation instructions which I hardly ever did at the time now and again, you guys will see in the video where I point out right now that exact thing that the trouble contact is wired backwards, so something to understand. Okay, so another thing and I'll get to some questions. If you guys have them a couple email questions I had, I thought this was a really interesting one, so I had a question from a from a technician that works on residential appliances and he you know he had a very nice email that applauded me. For my videos, okay, but then he said you know, unfortunately in his line of work.

He really appreciates the fact that I always stress looking at the big picture in my videos, but unfortunately, in his line of work because of the flat rate fees and stuff, he finds it very difficult to explain to the customer that they have other problems with their Unit after he's quoted it out. Okay - and you know his his words to me, were you know it's difficult to get them to approve anything else after I've quoted out a condenser fan motor, for example. Okay - and you know I emailed them back and I just said: look I I understand we're flat rate can be confusing and that kind of stuff, okay. But I really don't think that the appliance business is really too much different than the commercial side, which is what I do, because you know we should be looking at the big picture and diagnosing for the big picture from the start.

Now I understand that sometimes a customer just wants. You know that the flat rate can get a little confusing. I don't deal with flat rate on time and materials, but I still think that it's important that you know just because we're a flat rate company. We still need to look at the big picture, so you need to have some in my opinion, some disclaimers in there.

You know, like hey, you know right now. The first thing that I find is is a bad condenser fan. Motor bad Kenneth's family will cost this much, but here's the things that could be bad also because of the condenser family, there's always a possibility. We could have bad valves on my compressor if it's a r134a system, there's always the possibility that the capillary tubes can be plugged up later, if they're not already plugged up.

You know that's the kind of stuff, and I think that adding disclaimers to your diagnosis and your quote would help you to be able to sell a permanent fix after you change the condenser family, but I do see his dilemma in the flat rate: diagnosis. Okay, if that's the right way to phrase that I see the dilemma - and you know that's why flat rate really doesn't work on the commercial side per se, especially when you're dealing with restaurants. But still you know, I still think we need to sell the big picture and I'm not saying to to sell them things that they don't need. I hope you guys get that from my videos, I'm not about ripping the customers off whatsoever, I'm about looking for the customers best interest while doing my job properly, so that was one email.

Okay, next thing that I wanted to bring up was I had another question, and this may seem simple to some of you guys, but I think it's an important thing for people to understand. I had a person email me that he was installing a rotor lock valve on a compressor and he wanted to know if he would use standard 15 percent brazing rod on the rotor lock valve to weld it to the copper line. And I emailed him back and I just said: hey look, you know what most rotor lock valves. I honestly have never seen a copper rotor, lock valve.

Okay, I've only seen steel and brass, and I explained to him that when you're working with dissimilar metals that you're gon na need to use a silver bearing solder, that has more than you usually some I like to use. Fifty six percent is the silver solder that I use and silver sodding silver solder flux. You know that you got to put on the system - okay before you braze that silver solder on there. So it's important to understand that when you are working with dissimilar metals such as stainless steel, steel, copper and brass, you know that you need to use the proper brazing rods with those I will say.

I've had the opportunity to work with a few of their products and I'm not gon na give them a full fledged review yet. But I do have to say that solder weld has come out with some really cool new products that I think are awesome and I'm still testing out some of their stuff. So I'll have definitely a great review video, I'm still waiting from a microchannel coil. So I can use their aluminum brazing rod on it, but I do like solder welds brazing rod.

It was brought to my attention from HVAC school brian, or you know he was pushing that stuff really hard, and i was able to pick some up actually brian sent me some to try out and I'm really blown away. It seems like a very high quality product. The one cool thing I really like about the solder weld is the brazing rod, it's very unique because it's a round rod, so it's really cool. But again I haven't done a full review on it.

So we'll see um another really and I'll get to the chat here in just a second another, really really good question that came up was pumped down. Someone had sent me an email and they had asked me how come when you, when you pump a system down the head pressure, does not go up. Okay, now he did not give me context, I'm assuming that he was talking about a refrigeration system with the receiver and again this may be normal review for you guys in the chat right now, but I'm just gon na go ahead and talk about it. You know a refrigeration system with the receiver, the condenser and the receiver are sized adequately to be able to store the whole refrigerant charge in the condensing unit.

While it's pumped down - or at least they should be sized correctly. Okay, sometimes, if you use aftermarket condensing units, you all know we can run into those problems. But if a refrigeration system is sized correctly, you should be able to front-seat the king valve on the liquid line receiver and let the compressor run and what's gon na happen is, is there's enough storage capacity in that receiver and that condenser that that refrigerant can backup And there's still plenty of room for that refrigerant to expand in there and you can basically pump down the entire charge in there, and that would be why your head pressure would not rise an important thing to pay attention to, and that's why I stress to people You don't ever just put your low side service gage on a system, especially when you're pumping it down. You need to put your high side service cajon on there too, because you need to be able to monitor those pressures to find out if the systems possibly overcharged, and/or, possibly under sized to where you can't pump down the entire charge.

And I have come across that quite a bit, so that's when you would see when it was pumping down. You would start to notice. Your head pressure starts to rise and it keeps rising and keeps rising and I usually won't go. Let it go past about 325 psi and you know if he gets any higher than that, then I'll you know, go ahead and shut it off and to recover the remaining charge.

Okay, so just a quick question, I wanted to answer the last thing that I wanted to bring your attention is. I just want to say obviously happy New Year to you guys and thank you guys very much. This has been a really interesting year. For me, I've said it many times, I'm just a service technician.

Okay, I own a smaller co owned, a small business here in Southern California, and I started making these videos to help my own technicians. Okay, I had a situation where I had to hire three technicians. Pretty close together and they were all good technicians, but they just didn't know the way that we did things okay, so I started making a few videos with the interesting things that I ran into and how I handled them and that's what started this whole me. Making these videos on YouTube: okay, after seeing everybody else's videos, I decided to go ahead and make the videos public and the channel just blew up from there.

Okay, my channel officially started in November. I had like one video, I think I uploaded and I maybe had like two subscribers by April. I had a hundred subscribers and then here we are December 31st and I just crossed there 10,000 subscribers today, and that is all because you guys have taken the time to watch my videos and subscribe to my channel, and I just want to say thank you very, Very much okay, it's it's humbling to see that now I don't make these videos still to this day to make money. Don't get me wrong? I do make a little bit of money from YouTube, but that's not the reason why I do this, because the amount of time that I spend on these videos, the money that I have made does not you know cover that time.

I spend hours a day and I'm not asking for a pity party. I'm just saying I make these videos to try to share the little bit of knowledge that I have with you guys. Okay, I've made lots of mistakes in my career and I'm trying to share those mistakes and hopes that you guys don't make those same mistakes. Okay, so again, thank you guys very, very much.

Okay really really appreciate it. So I'm gon na go over to the chat and see if there's any questions that I need to answer guys. Okay, I'm gon na start back at the top. So just give me a second and I'll work, my way down guys: okay and thanks again Mike two nine five, nine for the super chat.

I really appreciate it then okay so go down and again I apologize guys about the whole mix-up with the video thing. Okay, so guys, if nightbot is kicking you guys out, I'm sorry, I don't. I may have a chatting on there wrong. I noticed that I kicked you out, JYP HC.

I do know that there's a setting in there to not put links in here. So I don't know if that's what you're trying to do so I apologize okay. Alright, let's see what I find. Okay, so ray-ray, you said answer to Belt issue.

If the fan is off it could smoke will travel to any positive airflow. The detectors usually in the return, but sometimes in the supply - I don't know the context of your statement that you made there, but I do see that you pointed out a good thing and I got another question on my facebook comments today was: where should the duck Detector be installed, it depends on your codes. I've seen them depending on the municipality in the city, that they're in they'll be installed on the supply and the return, but typically we see them on the return air side of the AC. Now, I'm not saying that's the only place to put them, they will work on the supply or the return.

I think that if you have two detectors it's better than one detector, because you could potentially catch a problem before anything else. Okay, I will say the downside to putting duct detectors in the return is, if you work with any restaurants that serve fajitas when they walk by the return. Duct you'll get a nuisance smoke detector trip, because the fajitas will get sucked right up into there. So I had a particular restaurant chain that was really big on fajitas and what they would do is put like a sizzle sauce on top of their cast-iron skillet, that they would serve the fajitas on, and that would make it smoke and sizzle and they would walk Out to the dining room right underneath the return air grill and constantly set off the duct detectors, and that was just a huge thing, because that brands biggest thing at the time was their sizzling fajitas.

So you know they weren't gon na stop that so it was just a nuisance left and right, left and right problem of going out having to reset duck detectors. That was a pain in the butt. So all right, gon na keep going down here. Yes, hidden resolve, you asked what type resistor, so the resistor is actually the alarm company's problem.

The alarm company supplies the resistor. I would not go in there trying to change resistors and in all actuality duck detectors are a very gray area because you don't ever want to mess with the alarm company's wiring, because it's it's gray on whether or not it can be considered a life safety device. I'm sure that insurance companies would be a little sketchy about you messing with them, but at the same time, in my area, the alarm companies, they will call you and say, or they'll, basically tell us to go change the duck detectors and that they don't touch those. But yet it's their wiring, you know some of their some of the wiring going into the duck.

Detector is theirs. So you know it's a very, very gray area as far as what size, resistors, that's determined by the panel, so the alarm panel determines what size resistor. You need to use. I will say that most of the alarm panels that I've seen - I don't - I don't ever open alarm panels, but I just know that most of the ones that are in my restaurants use 10k ohm resistors.

So I will keep a 10k ohm resistor on my truck, but I usually just for an emergency situation, but I've never used it. If I ever ran into a problem I would have, I would schedule a meet-up and in fact I'm having to do that right now. At a certain restaurant that I went out to where we had a bad duck detector and after I changed the duck detector, I found that the the alarm would never get signaled. Basically, and there was excuse me nothin wrong in my detector.

So there's a problem with the alarm wiring, so that's the situation where I'm having the management schedule and meet up with myself and the alarm technician and then we're gon na troubleshoot the problem together. Now I can 99 % tell you that it has nothing to do with me, but I like to show up just in case so that way when that alarm technician gets out there, he doesn't say: oh, you need to call the HVAC guy, and then we have A game back and forth over the next few weeks of both of us going back and forth, it's just easier, usually on my second visit I'll schedule. An alarm meet up and have the alarm technician show up with me and then that way I can be there while he's troubleshooting and then, if he has any doubt or any suspicion as to the problem being mine, I'm there to fix it and we can eliminate The problem at once so ok, gon na keep going here Alexander. You said that in Walmarts they time into the building management system - yep Gordon farmer you're, asking if there's any redundancies in the alarm, I could use a little more context to that to understand exactly what you're asking me there yeah Kevin Thomas crackheads have given up on Copper theft, yeah coppers, gone so low that yeah it's kind of not worth it to them half the time, but when it was at like $ 5, a pound for scrap copper, you know for number one that was when things were going hot.

So definitely definitely I will say that most of the time the there's no such thing as a smart, crackhead yeah. I guess I guess that's one way to put it Jo. 65. Let's see I'm going down through the Commons guys to see what we got here.

All right for those of you guys that are just coming in here or new people that came in we're talking about duck detectors in the trouble conditions. That's what I did talk about so and then now I'm just kind of going through answering questions. So, okay, so keep going down through here, see what else I'm missing guys reading through the chat. Actually, I can move this in front of me so that way it looks like I'm actually looking at you guys kind of.

Let me keep going here. Let me keep going see what I'm missing Tom trace. I'm assuming you said, 45 percent, that's what you guys usually is yeah, I'm usually a 56 percent person, but I have used 45 percent silver solder in the past and it does work. Fine so, and I've heard Alexandre I've heard a lot of people talk about the blue rods.

My problem with the flux coated rods is that I just don't know how to use them very well. I prefer paste flux because the flux coated rods, what I usually tend to have is is that the flux will break off before it gets into the joint and then I just have a problem with it. So I prefer paste flux, but again I'm not knocking any of the flux coated rods. It's just my inexperience with them and I just haven't had good luck with them but, like I said I do have a whole kit of the new solder weld stuff and they have a couple flux coated rods in there.

So I'm gon na give them a shot. So and see, hey guys, happy New Year to the guys that are saying that I really appreciate it. You know the or the cruddy thing is. Is that uh? I got a service call about an hour before the livestream, and I put it off so after I get done with the livestream.

I'm probably gon na have to go on the service call, which kind of stinks so alright, yeah a que does have a code for buying solder weld so yeah. You look on a case channel or DM him and he'll tell you whatever his code is to get hooked up with the solder world stuff. So alright, no Otis asked if I was going to the HR Expo. I am NOT.

I kicked myself in the butt for not setting not up sooner, but now I'm not gon na make it to the air Jar Expo this time. So thanks a lot ray ray. I really appreciate that all right, yeah Greg Burnett, you had said - are you sure, I'm assuming that you're saying to make sure your sample tube is pointed in the right direction and the cap is on the end of the tube of the duct smoke detector? Yes, that is very important. You need to follow the instructions on the sampling tubes.

There does need to be usually a short tube, that's about four inches inside one into the duct detector and then there's usually a long tube that should run all the way to the other end of the duct, and you do have to be careful when you have The sampling tubes that are like six foot long because they need to have support on the other end, usually what people will do is they will make them just long enough to where it just penetrates the duct and then they'll seal it on the other end. That way, it doesn't get any outside air in there, because when you get the the really long sampling tubes, the duct detector is just plastic and over time, the weight from that sampling tube will break the duct detector. So it's important to make sure you support your sampling tubes properly. If you just follow the instructions in the death detector, it explains all that.

So I I'm forgive me uh. I don't understand how to pronounce your name. It's oth RDA. I don't know what that stands for, but you said hey new here.

What advice can I give to someone trying to learn someone trying to learn? I would suggest read every book. You know YouTube is an interesting way to do things. It's funny ironic that I'm I'm here, caution you against YouTube, yet I'm making YouTube videos what I would suggest you do if you want to check the credibility of a youtube video, and you can't always trust what you hear on YouTube. Okay, but it is, there is lots of good information out there, but look at the comments.

The comments are a great way to to see if, if people are really trashing the person that has made the video, then you might want to steer clear from that. But I will say you need to be cautious about that too, because I can go in and delete comments from my channel. I don't I've deleted a few comments just because they mentioned the restaurant locations that I work at and I'll talk about that in a minute. But that's the only comments I delete.

I don't ever delete criticism or anything like that. I I embrace it so, but you do have to be careful okay, but I would suggest reading books depending on what side of the trade you want to get into commercial refrigeration for air-conditioning technicians by dick words is one of my favorite books. But I will say that's kind of an intermediate book: it's meant to teach refrigeration to technicians that already understand air-conditioning. So if you are completely green and don't understand anything that I suggest you start with something like refrigeration technologies.

The rack manual, I think, is refrigeration, air conditioning technologies or something there's lots of good books out there and then also check out HVAC school with Brian, or he has lots of great tech tips. And he does a podcast lots of great information and then, at the end of any of my youtube videos, I usually suggest and some other youtubers that have good content. So watch till the end of my videos and you'll see that and I those guys are usually pretty good stuff, so all right, Ryan, Leary holy moly hidden resolve. Thank you very much, sir wow.

I I don't even know what to say to you. Thank you very much Ryan Leary. How many texts do I have right now, I'm running four trucks, including myself, so I'm a small service company hidden resolve. I don't even know what to say to you.

Thank you so so very much man I Wow blown away dude. So yeah we're a small company Ryan. Just you know: Restaurant refrigeration. We we used to be a lot bigger and when I say bigger, the biggest I ever had was six trucks going and it was kind of crazy.

I don't ever want to get six again. You know I want to stay small while still having growth, but I want to. I want to be able, you know we're a family company, so we try to. We try to make sure everybody gets days off and we have time so you know we try to don't get too big.

Essentially, if you understand what I'm saying so, okay gon na go keep going down through here. Let's see, yes, you can cut the sampling tubes. Nando five: three: oh I've done that in a pinch just make sure you do it properly and that you can get the end cap in them. So if you want what you can do, but just make sure that the sampling tube holes aren't on the outside of the ductwork but yeah, if you want to buy a longer than normal sampling tube and cut it heck, yeah dude, it's just a piece of EMT Conduit, so you can just cut off the piece make sure you get rid of the burrs put the end cap in it and yeah you're good to go.

Man be cautious because a lot of the new duck detectors have a different sampling tube than the old school duck detectors. So remember when you go to change a duck detector make sure you take out new sampling tubes with you, so yeah rayray pointed out that you do need to make sure you look at the gaskets yeah. It's very important that the gaskets be on there just make sure you guys are following the instructions. There's lots of good installation instructions there.

So, okay! So what else I'm gon na go back up in here, Brian Milburn says: NorCal dave shoptalk dick wars book. It is amazing yep. Those are all great great ideas. So no I I do not know Andris any books about marine engineers.

I apologize, sir. I wish I did Gordon farmer, you said Google helps. Google does help man, you know there. You go refrigeration and air conditioning technologies, bill Whitman, Bill Johnson, yep great book and then also man, I'm trying to think of the Eugene silberstein.

I believe he's one of the authors of the ract manual on a side note. I am part of the arrowhead RSES chapter here in Southern California. We meet at San Bernardino Valley College and we are actually going to be having a winter conference where Eugene silverstein is going to be giving a discussion on air balance. So if any of you guys are local to me, reach out to me - and I can get you information on that conference - the tickets aren't too expensive, we usually don't you know, we don't really make a profit off of it.

Just basically covers our costs, but as our SCS, that's refrigeration, service engineers, society we have. This is like a special conference. We usually don't charge for anything, but just to plug my chapter, we do meetings the second Tuesday of every month, they're completely free. You do not have to be a member to attend our meetings.

We supply food for you guys if you want to come, we have all kinds of different topics every single month. So if you're interested in the our SES, I would look up our SES, org great training resource and they have chapters all over the United States. If you don't have an active chapter in your neighborhood, they also have a great website that has lots of great information on it. But if you can find a chapter here in Southern California, we have the long beach chapter, that's a very active and we have the arrowhead chapter in San Bernardino.

That is very active. Both of them, you know, are very, very active chapters and have meetings. I believe the long beach chapter is the second Wednesday of every month, and we are the second Tuesday, if I remember right, but if you're interested in either the Long Beach or the arrowhead chapter in San Bernardino, send me an email and I can get you more Information on that, okay, sorry, my plug - is over. Now that was my commercial for the day.

So yeah Ryan, you guys are six texts. Yeah, it's it's hard because Ryan was asking. If you guys didn't already see, he was asking me how many texts I have it's hard because we're a small company and we try to treat it small. For instance, we don't work off of a Pio system.

Okay, that's one thing that, but I have to trust my Tech's. You know, and I mean I still look at invoices and different things, but you know a lot of big companies work off a Pio system, so people don't steal from them, not that I don't want to do a POS system. It's just a pain in the butt and I don't have to go. I don't want it to be that difficult.

If I have to worry about my employees, it's just not worth it to have them as employees. So you know we like to stay small so that we don't have to worry about that stuff. You know we try to control the the stock in our vans. We try not to over stock but at the same time the guys they have a credit card and they got ta buy what they got.

Ta buy. You know, so it's just one of those things. It's a fine line, the bigger you get. You know if we ever do get bigger.

You know, then I don't know I may even eventually have to go to a Pio system with the text that I have now, but I trust the text that I have now. So it's just one of those things where I'd rather not, if I don't have to so all right, happy New Year to everybody. I really appreciate it guys so, okay, gon na keep going keep going through the comments. Looking what I'm missing here do I have any guidelines for how many hours to quote for repairs Alex okay, my guidelines, to quote repairs, are basically based off of my ability to do those repairs.

So you know I have some other technicians that may take a little bit longer so usually I'll add an hour to to my repairs. As far as guidelines go, it's it's a hard thing. I mean I don't know what kind of work you're doing. Commercial/Residential rules of thumb, if I'm gon na, do a compressor.

It's quoted at 8 hours for like an air conditioning system or something like that. If it's a small little reaching cooler, it's quoted at 6 hours, but then we're gon na add in you know all the materials that we're gon na use and that kind of stuff. But as far as a general number, I don't really have that. If you, if you have more questions, I can probably address that more in an email.

If you want to send me an email, anybody has any questions that they want to send me an email, its HVAC, our videos at gmail.com, and you guys can email a me anytime and I'll try to answer any questions. You guys have okay, okay, yeah NorCal does have a great vlog. The cool thing I like about NorCal Dave, NorCal dave is actually I watched his videos for years and his in. I wish that I had his his happy attitude that he always has in a sense of humor.

I wish that I had that the same thing I wish you know that I had aka Andrew grieves. I wish I had his filming abilities and his his though you know, even though he does more motivational videos. He. He really can explain things very well too, when he does do those videos every once in a while he'll have a topic will explain how something works and it's like man that guy has great abilities to do that and there's lots of other great youtubers out there.

You got my buddy Rick with Northwest Ohio HVAC, and then you got Chris Cassie with oh gosh darn it. I forgot your channel name Chris, I'm sorry, it's um I'll! Think of it in a minute. I apologize, but I always recommend them at the end of my videos, but those are great channels, there's all kinds of great channels and it depends on what you're looking for, if you want to get humor - and you know, there's all kinds of guys out there guys We can we can talk about that forever. I don't want to waste your guys's time on that.

Okay, gon na keep going down through the chat here. Okay, yeah Dave Tatro says when it comes to quotes for new guys always cover yourself. You never know. What's gon na happen, that's exactly correct and always have I always say to cover your ass in your quotes.

Yeah Northwest Ohio is, is Rick and then CSC refrigeration is Chris Cassie, that's a great one too. You just have to understand. He has a Boston accent but dudes, a cool guy, very nice guy, so okay, so how many years of experience do I have and my field trained guy or went to school to learn about HVAC, art, okay, Demetri? So for those of you that already know this, I'm just gon na say it again. I grew up working for my father, our partners now in this business, but when I was a kid I used to work with him in the summer time, when I was off school, my parents were split up as a kid divorced.

So a lot of times when my dad would come get me he would come get me like right after I got out of school, but then he would continue to do service calls for a couple more hours. So I can remember as young as I don't know, if I remember, but I've been told as young as like three years old going to service calls. Things are definitely different. Now I couldn't take a three-year-old with me to work anymore because of liabilities and insurance stuff, but back then dude I was climbing roofs.

I was changing swamp cooler, pads, changing filters on ACS. As a little kid now junior high. I decided that I wanted absolutely nothing to do with this trade. I hated it.

It was too hot, especially working in the Inland Empire, where we get in excess of about a hundred and five degrees average in the summertime. It was just too hot for me. I didn't understand it. I went through high school thinking.

I was gon na be an auto collision mechanic. I would like a body class all four years of high school and then went to work at a body shop, my junior and senior year, and it was at the end of my senior year that I decided I looked at my boss. One day he's a really really nice guy, but I just I just didn't want to do that anymore. I just wasn't what I wanted to do and I came to work for my dad at the time full-time.

So that was about 2002 and it's been going ever since him and I partnered up few years ago so now I'm co-owner in the business and we just run the company together now. So I learned in the field, but at the same time, when I started officially in 2002, I went to trade school. I went to my local Community College. Mount San Antonio Community College in walnut took night classes, usually like two classes, a semester never actually fully finished.

Like a certificate or a degree or anything, I think I was like one class shy or something like that. I think I needed to take welding and like technical math or something like that, but so I learned in the field from another co-worker that was working with us. I learned from my dad and I went to school at the same time and then since then, I've just made a lot of mistakes and learned from them. So and that's Here I am today, so I'm not the perfect technician.

I don't know everything I just you know I'm good at learning from my mistakes. Basically, so alright, let me go back to the chat. Okay, yeah, I don't know Randall as I I saw that going around social media about a refrigerator exploding down in Florida. That seemed a little excessive, but who knows ma'am? I don't know I'd like to see the report on that.

If someone ever says exactly what happened Jack thanks for coming in on the live stream, and I really appreciate it. Okay, two more subscribers and Chris will be at 13,000 about two wizza Brian, for whatever reason YouTube is behind I'm actually at 13 thousand subs it for whatever reason it's not showing you guys, but I get a different subscriber count. That's not delayed, and last I looked at it. I was at 13,000 and eight, so that was crazy, really appreciate it: okay, mmm! Yes, I do live in California and I'm sorry it looks like the moderator, nightbot blocked.

You, tiny man, the Beast, I'm assuming. As for putting in a link, I don't know if that's what it was but um, oh no! No, it just says I went to announce like yes, I did go to mount sac, tiny man, the beast, I'm sorry. I thought I thought it kicked you out, or it said it timed you out for something. Why? Oh it's because you use too many exclamation points.

Why sorry bud alright and then now it says no link. So I apologize okay, oh right, on very cool off from Australia, someone's watching this, that's really cool! Okay! So do you guys have any more questions? Gosh? I wish I could show that video. I wanted to show you guys. A freaking worked on that all day too.

Dang it, you guys, see the training board behind me at the beginning of the the livestream, I was trying to show a video that I made about troubleshooting the trouble contacts on the duck detector and unfortunately, I'm just gon na have to upload it to my channel. So pay attention to my channel after the stream and I'll upload the video I'll go and make it an extra one. For tonight, Chris EU asked what is the service call for the service call is for some cooks drawers in the back of a kitchen, and you ask why I would go out to that on New Year's Eve. Well, the service call came in around 1 o'clock this afternoon and today we everybody took the day off, so I was the person that was on call, so that was the only call that came in, but when it came in at 1:00, I was just doing the Math in my head on how long it might take so I put the call off so that's why I'm gon na go after the stream, because I didn't want to miss the stream.

Normally, if someone called about their cooks drawers at 6 o'clock at night, I wouldn't go because just cooks drawers if it was a walk-in or a freezer. I would go. But this is one of those situations where you know, I'm the one that put the call off. They called in at one I should have gone then, but I'm actually gon na try to call him and talk him out of it.

But the problem is: is that they're gon na want me tomorrow, but tomorrow is double time so either I go tomorrow morning. We'll see I'll deal with them here in a little bit so bird 203 have you ever gotten robbed by a customer or not getting paid right or equipment stolen, heck, yeah. I've gotten, I don't know about robbed, but I've had customers filed bankruptcy on us. We've had general contractors up and just disappear.

We've had yeah all kinds of stuff like that. I've had general contractors file bankruptcy, yeah. It's no boy know we try not to do new construction because of that reason we get burned by too many general contractors, but I've had restaurant chains. I don't do work for them anymore, so I can say their name, but El Torito Mexican restaurants, they own Acapulco.

They own Chevy's, all those they filed bankruptcy on us like ten years ago. We lost a bunch of money, then we haven't done work for them really since but yeah that was a bummer. That was a lot of money. Okay, tough working on units during lunch hours, yeah, definitely tough, working on units during lunch hours, and that was one of the things with the service called that the restaurant called me.

As I tried to say, like hey guys, you know we're gon na go into a it's gon na be busy like III, basically flat out tell them. This is a six drawer cooks chore unit, you know, wonder meat their grill, and I go you guys. I got to take every drawer out. I just basically get Morris case scenario, I'm assuming all the coils are iced up, so your cooks have to get out of my way.

I need to pull all the drawers out and all the food has to come out of that box for me to work on it and then that's what I'm gon na tell them when I call him right now and say so, are you sure when we come Out today you know, I have a feeling they're gon na say yes and then I'm gon na go out there and they're gon na say: oh no. We can't have you in here and then they're gon na want me to come back, but that's just the life of dealing with restaurants sometimes do smoke detectors age. Doug brown asks you know. If a smoke detector is properly taken.

Care of. I would say that it should last for quite some time. The one thing that happens with duck detectors or smoke detectors is: is that they're not maintained? Nobody ever maintains a duck call unless you're working in like a hospital situation or a high-end client. So, on a duck detector, usually on the older ones, they would have like a little protective screen over the sampling tubes and those protective screens would disintegrate and then get sucked into the detector head and caused problems.
