Ah, it's time to chill out and get ready for a mediocre. Qa 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 yo. How are you guys doing this evening? Hopefully you guys are doing well, I'm doing okay over here.
Finally, finally, over this, whatever cold I got after the ahr show, I swear that thing took like three weeks. Luckily, I didn't get flu-like symptoms. Mine was just more Moyne, have a hard time with my fray, of my words right now. Mine was just more of a cold, so thank goodness for that and it kind of passed around my family same thing.
They just got like cold like symptoms, so thank goodness for that, but anyways life is getting back in order. Things are kind of getting a little bit more hectic at work. You know I had quite a few installs and stuff that I was kind of putting off before the HR show and it seems like they've, piled up in the back of my shop. What happens is I do commercial work for restaurants, and you know one of the downsides to working for restaurants, but it's a it's.
A good thing, too, is that they supply their own equipment. So if I've got a lot most of the time, if you guys see a video of me changing walking cooler equipment, I'm not selling them that equipment. Okay. For the most part, the restaurant supplies that equipment.
That's one of the downsides to doing chain restaurant work the plus side to doing chain restaurant work. Is they keep you busy pretty much all year long? So you know, while other people are slow in the wintertime, the restaurants are changing equipment out, but anyways. I digress. You know it's just one of those things you got to kind of give and take a little bit, but so I've got like a backlog here of work that I need to do and I'm getting to it.
So I actually did my first heat craft, intelligent, evaporator, install evaporator and condensing unit, but the condensing unit is just a basic condensing unit, they're, just using an intelligent evaporator which, if you guys don't know, that's kind of heat crafts, newest smart evaporator. I guess it has a more into it. They say intuitive user interface. I don't know if I quite agree that it's more intuitive it's kind of a pain in the butt, and I will say that when I was doing the setup, I have to say I'm not gon na say that the text name, but I called heat craft tech Support because I got myself into like a little dilemma when I was doing startup and I got stuck in like a menu because there's a bunch of different menus, you can go through and stuff and I have some video footage of it.
But I don't know if I'm gon na post it or not, we'll see but anyways. I got myself into a little bit of a dilemma, and so I called technical support and brought to their attention. Hey. You know I'm doing an install and I kind of got into a little dilemma and I basically told him hey. I was hoping you guys could help me out in you know, setting this up and starting it up and the tech supports answer was kind of cocky. You know he he basically just said verbatim. Actually he said you know there really isn't anything difficult while setting those up. It should be really easy and I'm sitting you're thinking Walt no dust stupid.
I'm calling you for help so obviously something's wrong. It just kind of irked me a little bit with his response. You know, but anyways we got to figure it out, but yeah. So I did my first intelligence.
Startup I've got four more. I think, to do coming up soon so trial by fire. I guess, but hopefully you guys are doing well, I see there's a lot of people in the chat as usual. Guys, if you guys have questions, do me a favor post them in caps-lock, please, okay and the moderators will help to kind of field.
Those questions to me, as I always say, don't hesitate to keep re posting your guys's questions. If I don't answer it, I probably didn't see it. Okay, I will usually tell you guys up front like hey. I can't answer that question today.
So if I don't answer your question, just keep your posting. It I'll try to get to it. If I can. Okay, you're, not gon na piss me off until either myself or a moderator tells you to stop.
Okay, just don't ask stupid questions and when I say stupid questions, don't ask me, you know what refrigerant smells like or something stupid like that. Okay, but I have no problem with tech like remedial basic questions about soup. Well, not super you because those ones are more complex, but you guys get what I'm saying. Okay, just don't ask silly questions.
I guess I should say so, but hello to everybody. Okay, as I've been doing lately, I'm gon na start this off. As I usually do. My name is Chris: I'm an HVAC our service tech here in Southern California.
I do these videos to kind of help myself. Well, I make videos on YouTube to share the little bit of knowledge that I have okay, I started making them for my own service technicians and eventually made in public and it kind of turned into this machine that it turned into, and it's kind of crazy. So I get tons of emails, tons of comments, all kinds of stuff, and these live streams are a way for me to kind of consolidate those questions in those comments. Okay, because I might get 30 of the same question about a certain video that I post and I find it easier just to come on to this live stream and answer it publicly.
Okay, so a lot of times. If I get comments, emails questions, Facebook comments, Instagram comments, I usually, if I can, if it's, if there's not too many of them, I'll, usually funnel them to this live stream. Okay, I do these live streams, Monday evenings 5:00 p.m. Pacific time.
Typically, every week work permitting. It's been about a year and a half, I think now in the live streams, which is kind of crazy. That's been interesting, it's kind of crazy that I really haven't missed that many live streams but anyways. You know I have not been as consistent lately with the uploading of my videos, but I'll definitely try to get back in the groove. I was just kind of like in a weird funk coming out of the new year, but I'm feeling a lot better and things are getting better gotten. Some good footage. You know the biggest thing that I like to share with everybody is just my perspective. Okay, as a business owner that makes all kinds of mistakes, I try to share the little bit of knowledge that I have okay, usually, if I'm telling you hey, don't do this, it's because I probably did that.
Okay, pretty good odds that I did it or one of my guys did it okay, so I try to share knowledge so that way, maybe you guys don't make the same mistakes as I did. You know. So that's where we're at I'm gon na take a look here at the. Let me see if I long have I been doing this DNF garage, so I started in the trade officially in 2002.
That's when I went full-time, but I actually grew up working for my father, I'm 37 years old and I started working for him, probably in junior high. I worked the summers basically and I'm sure there was plenty of labor laws that were violated when I was working for $ 20 a day but hey as a 13 year old $ 20. A day was a lot because by the end of the summer you had like $ 200, and it was like. Oh my gosh.
What am I gon na do with $ 200, I'm gon na age, myself be cuz. What I did with $ 200 was. I went to the warehouse and bought CDs. That was my thing.
It's kind of funny, too getting away from the live stream. You know HVAC topic. I took my daughter to a music store because, like vinyl records are coming back, I was never into vinyl records but anyways my daughter's into him, and I took her to a music store. It was like walking into you, know the warehouse.
It was a trip like. Oh, my gosh, you know everything's categorized and anyway so getting off topic here, so we're gon na get back to HVAC stuff. So usually what I do is I come up with a list of things to talk about and then I also address the chat to okay. So again, if you guys have questions in the chat put them in caps, lock and we'll try to get to them.
Okay, I'm gon na kind of go on over here, real quick and see. If I missed anything, have I heard about the new r22 type. Mr. Johnny boy, mr.
Johnny boy, there is probably about thirty or forty different flavors of our twenty-two replacements. So have I heard about the new one, probably not there's a million different ones. Last I heard was that blue one was actually advertising before my YouTube videos. They have nothing to do with me, but they were advertising on YouTube and apparently they've picked my channel and they started advertising on my channel. I personally at this point in time: don't use any r22 retrofit replacements, but that's just my choice. Okay, I give it to my customers and I say: hey: do you want me to use the factory refrigerant? You want me to use an alternative and I let them make those decisions so at this given point in time. It is also about time that I go ahead and talk to all my customers again, because I do this about once every season before you know come springtime and kind of address them and ask them hey. Do you want me to try to use alternatives, and usually they say no so I'll, bring it up to the again and see if it's something what they want to do so, let's see, I do know that if you guys don't already know what you're gon na Start seeing popping up in your supply houses as of January 1st, I think any new you're going to start seeing basically all white drums of refrigerant, no matter what flavor it is.
R410A r22 are four: oh four they're all going to be the same color. So guess what we're gon na have to do now. We're gon na have to use our eyes and our brains and our reading and writing skills. I guess our reading skills and verify that we have the right refrigerants, which you know we.
We might have some problems with that, so that's gon na be something new coming up. What I want to say right now, since we're talking about different refrigerants, is I'm gon na give a plug to my buddy Ralph? I have no association with Honeywell refrigerants other than my buddy. Ralph is always willing to give me information. Okay, so my buddy Ralph works for Honeywell refrigerants.
I don't know if he's in here yet, because I haven't seen him in the chat yet, but he very well could be because I'm not staring at it right now. I always plug his email address. Anybody that has any refrigerant related questions about r22 retrofits or anything like that reach out to my buddy Ralph at Honeywell. Refrigerants he's always willing to help you guys out and always willing to answer questions.
So if you have anything, just just shoot him an email, he can usually get you the information if he doesn't have it. So all right, let's see what else we got. Okay, let's see it says. Jh possibly has a question for me.
So send me your question. Justin, let me know what it is: you've seen a lot about g m, -- geothermal Mike Jones yeah. We don't do anything with geothermal here, because our ground temperature is too high, but geothermal is a great energy efficient resource. If you have good ground temperatures, especially in the Midwest impact East, where they have cooler ground temperatures - so you know geothermal essentially is going to use the ground as a condenser essentially and you're, going to take your compressors discharge.
Gas you're gon na run it into the ground. It's going to act as your condenser and that's going to help you to save energy. Okay, so geothermal is a great resource. I imagine they could probably do something with some really cold ground temps with the evaporator. That's an interesting thought so anyways, but no, I don't do anything with geothermal at this time. So let me see what I got going on in here. What kind of 3/8 copper benders do I use so the copper benders that I use are they're very old. I've had them since I was a kid basically, I believe they're made by yellowjacket.
I don't know what brand they are, but they're the single brand lever benders. So if I remember after the stream, if, if I don't already send me an email and I'll try to put a show a link in the show notes of the video for the type of benders that I use, but I use the single type lever. I also have the ratcheting tubing bender that does like all the different sizes and I'll typically use that for 7/8 3/4 5/8, and then I have a half inch hand, bender 3/8 hand bender and 1/4 inch hand bender. So let me see what else I got hey.
Thank you very, very much for that super chat, Joe and since you did that, I wanted to go ahead and address something. You know I really appreciate, but it is not necessary for people to send these super chats through. It is awesome that you do that and thank you very much Joe, but I do want to say thank you, because there is some people and I don't quite address it, probably as much as I should there's some people that have taken it upon themselves to find My patreon page to find my youtube membership page or to Super chat on these live streams and again not required, but I really do appreciate it. I probably should go and name you guys all, but I'm not very good at that kind of stuff.
So I apologize, but you guys know who you are and thank you very much for those of you that have taken the offer that the you know taking it upon yourselves to donate to my channel but again not necessary. That's not why I do this. I honestly do this to share the little bit of knowledge that I have. So it is what it is.
Ok, let me see what else have I seen the new NRP quick connects for refrigerant piping? Yes, I have chris cooley. I have not seen them in purpose. In person, but I have seen them all over social media - I don't like to talk crap on anybody, I'm not a fan of new. You know quick connects for refrigerant and different things like that.
So those things honestly, I don't think I'm gon na be trying those out at this given time, maybe later once they become more popular or let other people test them out. I've seen some of the social media comments saying that they work I've seen some of the social media comments saying that they don't work. If you guys don't already know it's a quick-connect kind of like a sharkbite fitting. So it's not like the Zoom lock widths Portland.
The Zoom lock with spoilin uses gaskets or Owings inside in a compressor compresses the refrigerant line around it and makes a mechanical seal, but there's a new company out there that's doing quick, connects basically they're pushed to fit fittings kind of like a sharkbite and they're supposed To be rated for refrigerant again, I don't want to talk crap on anybody, but I'm not really gon na go down that road at this time. So that's my two cents on that one right now, when I was working on the large make upper unit. Why did I have? Why did it have a cell deck pad HVAC Smith? Okay, so here in Southern California, our make up air needs to be conditioned for the cooling season. Basically, okay, so the large make up air unit that you're talking about was probably the big captive air unit and it had heating and cooling essentially, but it did not have refrigerant cooling. It had cell duck pads, which essentially takes evaporative cooling and runs outside air through an evaporative media pad or a cell deck pad and cools down the outside air, so that really works in dry climates, we're in Southern California. We typically have a dry climate. Our average humidity for the most part in the summertime is anywhere from 10 to 25 percent and really really humid. Monsoonal moisture is when we get really sticky outside it's about 50 % humidity.
So we do not know what humidity is here in Southern California. So with that being said, because we have pretty mild humidity, it can be cost-effective for the restaurants to use evaporative cooling as a cooling means for the restaurants. Okay, now it's not perfect. They typically only use it in the kitchen because it does make it kind of muggy and swampy in the kitchen.
But yes, they do have cell deck pads, or sometimes we use swamp coolers to help cool off a kitchen and typically it's because we can have really hot summers where we can't be bringing outside air. That is an unconditioned into the building because we might have a summer, our average summertime temps in Southern California about 110 to 112 degrees. So if you're dumping 112 degrees into the kitchen as make up air the kitchen air conditioner, if there is one, is really gon na struggle to maintain temps. So oftentimes they'll try to pre-cool that air with a cell deck pad or something like that.
But even that can become problematic too, because you know then you're dumping moisture-laden air into the building. So then the air conditioner has to try to dehumidified that air first. So it's kind of like a never-ending battle. Okay, perfect situation is you have a dedicated outside air unit that has DX cooling or refrigerant cooling, basically, and it dries the air out and brings it into the building, but most customers don't want to spend that kind of money.
So all right, let's see what else I got going on here. Let me see seeing what I miss in and then I'll get to my list of stuff. Can I explain the steps I took to start my own company Logan Bailey, so I can't take credit for starting my own company. I did not start my own company, I partnered with my father, so my father started our company in 1987. I think and worked for him as a kid grew up in the trade and basically partnered in the mid-2000s, and we run the company together. Now my dad does not work anymore and he is, he still works in the office. He comes in and gives me support and helps me out in there and every once in a while. He'll come out into the field, but he does not have tools anymore and he's not out driving a service truck anymore.
So I cannot take credit for starting my own company. I have just taken it over and have been. You know trying to not pull my hair out, which is part of the reason why I shaved my head, because that way I can't pull it out, cooling and refrigeration guy. Thank you very much for that super chat.
That is amazing. That is awesome. Thank you very much bud. All right do I know anything about spoilin wireless service, probes, Kelvin.
So yes, this morlin, smart, pro R is they're, very long-range probes and the spoilin smart tool, I think, is their non long-range probes. They make temperature clamps and refrigerant pressure gauges. They are bluetooth compatible and they do work with the measure quick app, I have been told. I personally have not used this morlin pro-r tool or the smart service tool, but I have heard nothing but good things about them and it is in the works right now, where I'm probably going to get my hands on a set of the smart pro-r tools.
I will say one of the smartest things that's Portland ever did was probably partnering with measure quick, because when it comes to diagnostic apps, the measure quick app is hands-down the best app out there. So if you guys don't already know what the measure quick app is just look up, measure quick on the Apple Store or the Google Play Store and just download it. It is an amazing app. It works with many of the probes out there.
The field piece probes, the test, o probes, that's Portland, smart, Pro R, I'm sure, there's more, I just don't know them all. I manifold. I don't know if it works with the UI uei ones. I think it might but anyways it's an amazing diagnostic app that helps new techs and experience text by consolidating information so definitely check it out.
Let me see being a spoilin fan, why don't I use zoom, lock hashim, it's just not something that has been useful for me at this time. I have nothing bad to say about zoom. Look. I just haven't run into a situation where I found it practical enough to use the zoom lock versus braising something, but I have a lot of walk-in installations coming up at this time and I would like to go ahead and try it out.
So I've been talking with them and we're gon na try to set something up where at least I just get to show it on video, just showing how it works and stuff. But I think we're the spore'ln zoom, lock, really comes in handy and probably the best place, for it is a situation where you have a crap-ton of braze joints in hospital situations where you have burn permits that you have to get fire watch and all that different Stuff, that's where it's really going to come into play in the restaurant stuff that I do with deal with. I'm dealing with tight little quarters a lot of times: 3/8 half-inch suction lines, that kind of stuff. It's a little bit not very practical to use the spoilin zoom lock, but on my walk in installations, that's where it can really help me out, I'm sure! So one of these days, I'm definitely gon na get my hands on it and we're gon na right out and see if we can't get some video footage of it, because I've been waiting for a while just kind of listening and kind of testing the waters with The zoom lock - and it has pretty much been proven that it is an amazing tool from everybody that I've talked to. They all seem to like it so long as you follow the proper installation practices and using their depth gauge and marking the fittings deburring. Your fittings. Basically, everybody that I've talked to says it's amazing, so I think it's definitely time that I jump on board and try it out so hopefully soon so all right. Let me see what I got going on in here: cooling and refrigeration guy.
It looks like you're trying to ask me a question. It looks rather technical. All do me a favor and send me an email to HVAC our videos at gmail.com, and I can probably answer that question a little bit better. If it's a crazy technical question, you guys have definitely send it to that.
Okay, I got a movie quote popping up in the night are in the the moderator queue tonight and let me know if you guys can figure out what movie that is. This is a mid-90s, coming-of-age movie, very good movie, very funny movie, let's see if you guys can figure it out. So all right, I'm gon na go and get to my list real, quick and then I'll definitely get to the to the chat a little bit more. Okay, so um uh.
I wanted to start with something right now, so I've been wanting to do this for a very long time, but I've been questioning whether or not this is the time the place to do it. But I'm just gon na go ahead and say it. I'm gon na make an official video on my channel, but I figured I'd throw this out in the live stream. First, okay, just like everybody else in the industry.
Right now, I am hiring okay. I am ready to take on a new service technician. Okay, I am considering hiring someone with experience, but I am also willing to hire someone that is new, but I do ask that you think about a few things before you send me any information. Okay, first off you guys see my videos, you see the kind of work that I want to do.
I am not perfect, but I strive for perfection. Okay, there's times that you know, I may have to cut some corners, but I do my best to cut corners and still strive for perfection. I like to follow proper refrigeration practices, but I definitely don't want to do a half-ass job, so I am looking for the service technician that is wanting to work for me and that is wanting to try. I am looking for the service technician that wants to learn for the service technician. If you already experienced that's willing to change. Okay, that's willing to spend the time to do things right all right. If you're interested in possibly sending me a resume, send me an email to HVAC our videos at gmail.com now, like I said, I will put an official video out on my channel we'll do that soon, but I figured I mentioned it in here. Okay, but you know one of the things a couple things that I want to point out.
First off is: if someone's interested in working with me. First off, you need to live local to me. I'm not gon na fly you across the world. That's not gon na happen.
Okay, that's not very practical. You need to live local in the Southern California area, specifically Riverside ish area Inland Empire is, is a must. Basically, okay, you need to be willing to work with a small business. I am NOT a big giant mega corporation okay, we like to keep it somewhat small.
I don't want crazy growth. All right, I don't want to become some giant mega company. We just want to do a good job. We want to make an honest wage and we want to serve the customers and - and you just make sure that they're happy with us.
Okay, I have a reputation with my customers and I want to try to maintain that reputation. Okay, I will say this because I know there's a lot of problems and people get pissed off about this. We do have GPS in our vehicles. Okay, we do have you know we, we we don't have dash cams or anything like that, but that's something that I might consider in the future.
Okay. So if that stuff irritates, you don't bother sending me an email, okay, but again I'll, put a more formal thing on my channel soon. Sometime but yeah definitely send me an email, HVAC, our videos at gmail.com. Okay, all right talked about the intelligent heat craft install.
I did this past week. I definitely learned a few things, but it I'll write installation. One thing I will say about the intelligent, evaporators, the new heat craft, digital evaporators. I learned something really quick.
They come from the factory with the electronic expansion valves fully open. So what that means is, do not apply power to the units you can purge with nitrogen. You can pressure test before you have to energize the evaporator. I learned that one by talking to technical support, because I energized the evaporator put the unit in cooling and assumed that that's what I needed to do.
But I found out after the fact that they come with the expansion valves fully open. So if you're ever working on an intelligent, evaporator do not hook up power, go ahead and purge with nitrogen go ahead and braze everything in do your pressure test and then apply power to the unit. So that's something I learned. You know because I don't know everything. Okay, all right, let's see what else got a couple questions that I want to get to. Okay, Stephen had asked me a question in the youtube comments or I don't know if he sent me an email, but he said how and he's reading he I believe he said he was just getting started in the trade and he was reading the commercial refrigeration for Air conditioning technicians by mr. dick wars, this book, that I always recommend that I happen to have sitting right here and he was asking a really good question. He said how does he know when he walks up on to a condenser what the design TD was for? The condenser, and likewise what the design TD is for the evaporator and unfortunately, there's no way to I mean the only way to know for sure is to get ahold of the manufacturer.
Okay, but we have some rules of thumb. We can typically say that if your I want to say, if your condensing unit or your air conditioner was pre-1992, it's probably gon na be 8 to 10 seer or probably a 30 degree condensing temperature over ambient for the condenser okay. As far as the evaporator TD, the evaporator TD is designed by the engineer. So if we're working with an air conditioner mm 35 degrees, something like that, it just depends okay, so you have to use some rules of thumb and some common sense to kind of know.
So we don't all know for sure what our TV's gon na be there's, not a definite answer. I can give you, unless you call the manufacturer direct and you ask them: what did you design this unit as now? Here's another thing: sometimes, when you call refrigeration manufacturers, especially like reach and refrigerators, they don't know what the design TD is right, because you're just dealing with the technical support person, but all you have to do is say: hey when you're calling about a refrigerator, let's say You're working on a delfield refrigerator, okay and you call tech support and you say hey. I got a question: what should my suction pressure be because a lot of times they don't really pay attention to superheat or subcooling, or even saturation temperatures when you deal with refrigerator manufacturers, they deal in pressures. So just ask them hey what should my suction pressure be? In what temp should the box be and they'll say you know 40 psi and the box temp should be 39 degrees? Well, you can figure out the evaporator TD with that information, because all you have to do is take the 40 psi, convert it to a saturation temperature and then your box temp is your return air temp, so you can figure out the evaporator GD same thing when You call a manufacturer if you call carrier technical support for a packaged unit and they say yeah. Your suction pressure should be this and your your endure temperature should be this. You can figure out the TD. You just got to do the math okay, so even if the manufacturers aren't willing to give you what the TD is or what the saturation temperatures are, you can just ask them at what temperature it built. You know return.
Air temperature is this particular suction pressure and they'll. Tell you okay, so there's ways to get around that stuff, but as far as a blanket answer as to what your TD should be, I don't know you got a lien on the manufacturer. Okay, so there's some rules of thumb that we use and there's, but but the the only way to know for sure is to lean on the manufacturer and see how they design that equipment, whether it be a walk-in cooler, whether it be an air conditioner, a chiller. Whatever it is, you got to ask them on a chiller.
You know if it's a water cooled chiller, you need to know what the incoming water temperature is. That's gon na help you to find out what your condenser TV should be. So all right, I'm gon na get to one more question then I'll get to the chat. Okay, Oscar had asked me again, I think through email.
He asked me what ice machine cleaner to use to clean ice machine parts. Okay. So whenever it comes to ice machine cleaners again you want to lean on the manufacturer now I'll, give you a blanket statement and tell you that if you're working on a hoshizaki ice machine, you're pretty safe to use the clear phosphoric acid, cleaner, okay, so clear, new Calgon cleaner is the safe one to use with Hoshizaki. You need to be careful with Hoshizaki, because Hoshizaki specifically tells you not to use citrus based cleaners.
A lot of the nickel saved cleaners actually use citrus acid instead of phosphoric acid. So Hoshizaki has said that the citrus acid can affect their solder, that they use to solder the evaporators together: okay, not the refrigerant lines, but the refrigerant line to the stainless steel evaporator. So you need to pay attention to each particular manufacturer. So when it comes to a hostess Aki ice machine, you use that the best bet is to use Hoshizaki scalloway cleaner.
But if you're not gon na, do that, you can use the clear ice machine cleaner. Just don't use nickel safe! That has citric acid and pretty much across the board if you're working on any other ice machines, the safest bet is to use nickel safe. Only Hoshizaki is the only one that I can across-the-board. Tell you that the phosphoric acid cleaners are the safe ones or the clear new, Calgon, okay or yeah, so because the viper products doesn't make a clear, Viper pot.
But I will say: refrigeration technologies makes a Viper ice machine cleaner and they don't use citrus acid. I don't think they use citric acid in their cleaners, but actually you need to read the MSG MSDS or talk to the manufacturer of that particular cleaner to to find out if it has anything in it. So the safest bet, though, when it comes to any ice machine, is to use the OEM ice machine cleaner. I don't think Scotsman makes their own cleaner, but I know that they'll have a recommendation on which one to use but, for instance, full at ice machines full at ice machines, uses a citrus based cleaner. They have their own brand and folded ice machines for the most part, unless you're working in some of the like chick-fil-a's and different things like that. For the most part, full at ice machines are used in hospital type environments, and they, your best bet, is to use the OEM cleaners only when you're dealing with hospitals, because they have all kinds of different health rules and different things. Okay, so your best bet is to lean on the manufacturer to ask them what types of cleaners - okay, but it's safe, bet to say if they tell you to use one cleaner on the evaporator you're, pretty safe, to use it on the parts for the ice machine Too, so all right, I'm gon na go ahead and get to the chat and see what I missed. I'm sure there's some stuff that I missed in there and let me see if I did go ahead and throw them in there again.
Okay, let me see yeah. Definitely type your questions yeah triple check with the manufacturers, as ernesto says, for sure. Let me see what else. Okay, I don't see any other questions.
Okay, yeah! I don't see any other questions. You only work for a company who puts a chip in you. Chris Cooley says: okay right on. When do I need a hi trap? I don't know why give me some context to that question.
What do you mean by hi trap? All right, I'm not seeing anything else. So if I missed you, guys's questions throw them in caps. Lock again, okay, you would like to hear why why I feel I need GPS, what drove me to that decision? So we use GPS and it's actually in our smart phones, it's not in our vehicles. It is something that I may consider putting in my vehicles, but we use GPS.
Basically, one of the reasons is for dispatching okay, but I don't have a dedicated dispatcher, like most big shops do, but when it comes time to figuring out where someone's at it's easiest to pull it up on the computer and say okay, this person's over here, the Next reason why I have GPS in my vehicles is to answer customers questions. I get a lot of complaints from customers that say your guy didn't show up at this time. He showed up at this time and they're contesting the bill. Basically, because we have GPS and our smart phones and it works with our invoicing program, it's very easy for me to say: yes, the cut my technician was there and yes, my technician did leave at this time, because I have a GPS time stamp.
That says, you sign the invoice and I have a picture of the invoice that you signed at this time and here's his GPS location. You know so it basically diffuses problems that we have it company. For other reasons, I don't have this need to do GPS, but you know to give argument and to give valid to validate other people's reasons for using GPS is just for pure wondering where your vans at what happens - and I have had this happen in the past When I didn't have GPS, I had a technician that just didn't show up for a week and a half, and I wanted to know where my service van was and it sure would have been nice to be able to pull it up on GPS and say: oh Here's my service van, even if I can't get ahold of them, I could drive over there and go get it so you know you got a figure to that. My service and I have 60,000 dollar vehicles, rolling down the road and that's not even fully loaded. So you know a $ 60,000 vehicle rolling down the road. I should be able to know where that it is any given time right. So it's very important that we have that now on a personal know, if I honestly was working for someone - I I don't have anything to hide me personally and I'm not a speeder. I don't you know so.
Gps would actually help me as a person. If I was working for someone, because I would gladly let someone have GPS in my vehicles, because it would protect me in a situation, you know so but anyways that's a whole nother thing. I know it's a hot ticket item, but it's just one of those things. You just got to deal with so all right.
Let's see what else have I ever used the KE to temp electronic expansion valve hashim. I have a system that came factory installed with akita therm evap efficiency controller in it, and it was fully set up from the factory with their expansion valve. I have not had very much experience working on it. I haven't had very many problems with it.
I think I had to change an evaporator or an air temperature sensor on it, but that was about it so nothing bad at all. Let me see what else. Let me see what I'm missing in here. You actually love the GPS says Ernesto.
You know some people do some people, don't i I really don't again see the big deal with GPS. Okay, it's I got nothing to hide, so I got no worries about it. So, what's a good load calculation app for refrigeration, coolers and freezers, what I will use rustle refrigeration! If you go to HT PG, I think it's HT PG calm, which is heat or which is a Russell refrigeration. They have a load calculation.
Software called. I can't think of the name of it huh I have to think of it for a sec. I can't think of what they call their load calculation software, but they have a load calculative out it here in a minute and I'll pull it up. I think it's called rust box, that's what it's called rust box yeah.
They have a good one. Trenton has one yeah. I am gon na mess with you guys here for a minute, and I am gon na have to take a bathroom break so hold on just one. Second, I'm gon na pull up this intro picture.
I apologize give me one second, and let me see if I can pull this up transition this over. I'm gon na do intro music for a second and I'll, be right back! My apologies for that. My bad, but anyways we'll get back to this right now. So alright uh yeah exactly too much apple juice. So let's continue the tradition there all right. Let me see what I got missed in the chat here, real, quick and then I'll get some more of my questions. I want to answer so. Let me see what else we got um yeah.
No, I'm not taking a sorry, hey, that's funny! I need to have something like canned interview or something like that to mess with that. How do I quote any a hoshizaki evaporator change out? That's a really good one! So I'm gon na be honest with you. I have never had to change an evaporator and a hoshizaki ice machine, but if I did they're really not that hard, it's like to braze joints, but if I was gon na change and evaporate around a hoshizaki, I would more than likely change the expansion valve or Both the expansion valves if it has to and changed the liquid line, filter dryer at the same time just personal preference. But if I was to quote a hoshizaki evaporator change out, I would probably quote it for eight hours, a recovery charge and all the fancy stuff.
It probably isn't gon na take me that long, because I know they're super easy to change, but that's what I would do it I usually my blanket quote is usually eight hours. So, let's see what else I got, what do I recommend doing to better my electrical troubleshooting skills? What am i, what do I recommend doing to better the electrical troubleshooting skills? You know I get that question a lot about. What's the the tips I have for electrical troubleshooting and that's an interesting one, I really need to reflect on that one a little bit more because I need to come up with a blanket answer. I electrical came pretty easy to me.
So let me think about that. One do me a favor and send me an email to HVAC our videos at gmail.com, because I'll try to come up with a good. Let me try to find a good book that will help with electrical skills. I realize that a lot of people have a hard time with electricity and it's just something that never really came difficult to me.
I had more difficulty with the refrigeration side, so send me an email, H, videos at gmail.com and I'll try to answer that for you Ernesto. You asked me if I had met a K at the HVAC R or the hea hrx bone. Yes, I did. I actually met Andrew Greaves aka HVAC at the HVAC, our training symposium at Bryan ORS office in Clermont Florida.
Basically, because Bryan had a big training Expo at his office. I had the opportunity of meeting a K and I got the honor to at the thank-you dinner for all the sponsors and speakers and different things. I got to sit down with dick words with Andrew Greaves, with Jim Bergman and with Bryan door and have dinner with them. So it's really cool to be able to meet those people. They were all very awesome people. It was really interesting, but yes, Andrew Greaves was a really cool dude to meet, saw him at the HR Expo also. He was obviously working then, but we had more time to talk at the dinner that we went to. That was really cool, so it was really neat to get to meet him.
I met a lot of other cool youtubers too got to sit down and have dinner with Gil kV from HVAC uncensored got to have dinner with HVAC rookie Scott got to meet a lot of other people, so it was really cool event. All right. Let's see what else we got going on, what roughly is my cost per vehicle for GPS? That's a really bad question to ask me because once I sign up for things honestly out of sight out of mind - and I forget what I pay for them so feel free to send me an email. But I pay for my GPS through my app that I use for my invoicing and stuff.
The invoicing program that I use is called Intuit field service management and it comes with GPS and all that stuff and it just uses the GPS and my phone. So I don't have a standalone GPS in my vehicles or anything so send me an email. We could talk a little bit more about it. What is my favorite type of roof membrane to work on just the standard asphalt, tar roof stuff? I hate the rubber PTO roof or whatever that's cool, whatever that's called, because I'm afraid I'm going to damage it if you leave screws on it, you'll poke at that kind of stuff.
So I like just the standard tar roof. The only downside to the tar with like the little pebbles all over it is that in the summertime like when you get crazy, hot temperatures like above 115 degrees that stuff can kind of get a little sticky and mushy. So it's a little bit sketchy walking in it, then, because it gets stuck in your boots, all right, let's see what else I got if I missed questions, guys feel free to throw them down again. Okay, let me see what else Bill's in here, how you doing man all right all right.
Let me see what I'm missing. What is my favorite type? I already answered that question. Okay and okay. I'm gon na get to the questions that I have on my little list right here.
Okay, so Donald had asked me what books and or PDFs that he could look up for learning more in the industry, okay, so first off when it comes to refrigeration work. I already said this before commercial refrigeration, for air-conditioning technicians by dick wars is my favorite book. As you can see, it's not some crazy thick book. It has a lot of information packed in there lots of rules of thumb and helps you to understand the basics of refrigeration.
That book is written for an air conditioning technician, that's transitioning into refrigeration. As far as what PDFs, what I suggest is is whatever equipment. You're working on, if you work for a restaurant company, if you work for a commercial industrial company just whenever you're on the roof, take pictures of equipment, take pictures of models and serial numbers and download the PDFs from the went manufacturers websites. You guys have so much that the availability of resources is amazing compared to when I was coming up and imagine compared to people that came up before me. Okay, I came up in a time when you know cuz, I'm 37 years old. So I remember when the internet wasn't a thing: it wasn't something that people can afford. Okay, the first social media I had was myspace Facebook. I didn't even get involved in Facebook until you know, like 2004 2005, or something like that.
So I remember having to read Thomas guides too. You know we didn't have maps. You know the MapQuest was the first one to come out, but you guys have the ability to have everything at your fingertips. You can download anything heck.
You guys can look up a video of me fixings, something that can help you guys. You can look at this livestream so use the resources you have and just Google search anything anything you're working on just Google search it. Okay, if you're. If you have a question about something, a very great resource as a website called HVAC talk, comm, it is a message board that is a great resource.
There's lots of good information on there. Also, my buddy Brian Orr has a website called HVAC our school comm. He does articles and podcasts and also does YouTube videos so check out that website, too, has lots of great information on it. I've actually written some articles in the past.
I haven't done anything recently, but I've written some articles for Brian to storm asked me. How do I have my text? Respond to billing questions from customers seems a lot, want answers on costs and different things. So, for the most part, my service techs really don't have to deal with billing. The customers anymore for the most part they're just getting a work order, signature and in the office we handle the billing.
There is times that the customer may say you know. While my service tech is on site and they say hey, how much does this cost to fix and my tech might have to give them a quote, but usually he's leaning on us and we in the office take care of most of that stuff. So in the past, our service techs used to do everything from quoting to billing to everything, but these days service texts for the most part, don't have to do much with the billing stuff anymore. That's another thing, too, is the responsibilities of a service text.
These days have really dropped off so the way the my service techs. My service techs literally, have to check in and check out on a job. They have to input their times. They have to put a description.
They have to put equipment, information, the invoice they have to fix the equipment and they have to get a manager, signature and that's about it. In the office we handle the billing we handle the quoting. We handle the emails, we send pictures to facilities that kind of stuff. If there's customer complaints, I will of course encourage my tech to try to resolve complaints while he's on site, but you know for the most part, we'll deal with all that stuff. Once they're gone, let me see what else I got in here. What's my motivation to get through tough days, that's a great question: Sean Mack huh I've had a lot of tough days lately. What's my motivation to get through tough days? That's you know, I don't know I'll have to think about that one. But that brings up a great point, something that I thought about today and I wanted to point something out.
I actually said it in a video clip that I'll probably post soon is that you guys that watch. My videos actually hold me accountable, because today I did a really great video working on a kitchen AC and then, when I went to the site, I posted something on Instagram that the customer had asked me about another air-conditioner that wasn't working, because I was talking to Them, and so when I was done fixed in their kitchen a/c, it was time for me to dive into the other AC. So I went ahead and fixed it. It was an electrical short and I'm gon na be honest with you.
I felt like I wanted to cut some corners because I fixed the electrical short I turned the unit back on. It wasn't tripping the fuse anymore. It wasn't blowing the fuse anymore and had a good temperature differential across the return in supply, and I really didn't want to put my service gauges on the unit because I knew it was probably gon na be okay. But I went ahead and did it because in my head again you guys hold me accountable.
I was thinking well, I already started a video for this and these guys see me fixing stuff and checking all these things. So the point that I'm trying to make is, I ended up going through all the steps that I should have gone through, that I always preach in my videos, but guys just like you guys, there's times that I just don't want to take all I don't want To look at the big picture sometimes sometimes I just want to fix it and move on okay, I'm not perfect whatsoever. Don't think that I do this crazy, amazing repair every single time, I'm just a normal dude. My stinks just like yours, okay, so there's times that I don't have the motivation to spend a bunch of time fixing something all right, but I tried to do my best again.
I strive for excellence. I can't always be perfect, so you know what gets me through. Those bad days well in that situation. You guys got me through that, because I was thinking I got ta make this video.
I got. Ta show these guys that I'm you know I got a hold up to what I'm preaching all the time. Big picture diagnosis, all right, JJ services. Thank you very much for that super chat dude.
That is awesome. I really appreciate that. Okay, so you know what gets me through the hard times. Is my family all right thinking that you know what I've seen a lot of bad things happen? I've been through a lot of bad experiences at work, and I know that there's gon na be another day right. I know that guess what tomorrow is gon na come so today may be crappy, but tomorrow is Tuesday and the next day is Wednesday and then guess what we'll be on a Monday again in a week, so yeah stuff happens, yeah bad things happen, callbacks whatever, but Life goes on and it moves on with or without you, so you can dwell on it and again I don't I I again. This is a stuff I try to live by, but I'm not always perfect, but you can dwell on it or you can just take it as it is and just deal with it and move on, because tomorrow is gon na come no matter. What and life's gon na move on, so I don't know if that answers anything. I don't know if I really went off on a weird rant there, all right, let's see what else.
What did I miss in here? Hey mr. Ted, how you doing, but all right are there any remote diagnostic tools for before I even walk onto the roof or into a cold box yeah. There is there's actually a lot of great remote diagnostic tools and there's more coming out every day. So there's a program called since II predict that's a remote diagnostic tool for residential applications and light commercial applications, and it basically is something that you would sell to the customer.
It has a lot of diagnostic tools and it tells the customer when they need to call a service technician, because what you essentially do is you Commission the equipment using the measure? Quick app, you say this is the baseline. This is how it should work and, if anything deviates from that baseline, you know benchmark then it'll alert, whoever it needs to there's also remote monitoring equipment for refrigeration equipment that I can log on to customer sites. I actually have a customer that has internet-based thermostats that have some diagnostics in them. So if the customer calls me and says hey my air conditioners, not working, I can log on and I could say: oh yeah you've got five AC units and only three of them have temperature differentials across return and supply.
So it looks like you have a couple units or I can even say hey, you know what there's a unit offline. Do you want to try to jump up on the roof and see if someone left it off, you know so. Yes, there is remote diagnostic equipment. Most customers don't understand or don't want to go that path right with the internet of things.
You know weird crap going on with hacking and different stuffs, but you know it's very interesting where this trade is going. Okay, this trade is going to remote diagnostics. Basically, so let me see what else I got in here. How do I deal with a customer who is not willing to pay or delaying the payment? So Hashim I've had many of those that's one of the plus sides to dealing with chain restaurant work for the most part chain. Restaurant work. They pay you, you agree upon a price, you do the work and they pay you and you're gon na get paid. Okay, sometimes some of the small mom and pops it can be hard to get paid. Okay, I've gotten so much satisfaction out of walking up to a bar one time and basically working on the ice machine, telling him that the ice machine wasn't working right and the man or the the owner of the building.
I love supermarket refrigeration. It’s definitely a grind though. I’m only 22. Can’t see it any other way at the moment Are you in Nepean ?
Can I use appion recovery machine to recover R-1234YF and R600a refrigerant?
I missed it 🙁 I can watch it now 🙂
👍😎
Hey I hope you don't think I was trolling or got offended by my asking about mega tests the other day, our language between countries is so different lol, and the breakdowns here are fairly different to there, so I was asking out of curiosity. Great videos by the way 🙂
Any ideas on where to find a 1986 trane weathertron wiring diagram?
