All right, we're live guys, how's everybody doing tonight for those of you that are watching this after the live stream. If you don't already know, I'm communicating with the chat, so if you come in on the live stream, when I share this the link to this, you guys will see that there's a chat going on, and so people can ask questions. So if you guys get the opportunity to come in on a live stream, I suggest you do so because then you can ask me live questions, but the whole purpose of these is to answer questions from the videos that I do so you know I kind of Come on here I what what I get is I get a lot of questions and emails about different things within the videos and I try to answer as many of them as possible, but sometimes it's a little difficult to answer them. So that's why I come on and do these live streams so that way I can answer and address some of the common questions and different things.

You know in this live stream so again for those of you that watch this after on YouTube, you know consider coming on with the live stream. The us can communicate with me live and you know, send questions through the chat and different stuff, so alright, guys so uploaded video today on the ice machine service, call that was the ice step, hoshizaki ice machine and then the last video I did last week on Friday was on the delfield reach-in cooler that had a temperature controller that was bad, but before I get into that, I wanted to share a funny story. I don't know if you guys follow my facebook. I have the HVAC our videos on Facebook.

If you don't go over there, you can friend request me because it's an actual profile - and I also have a page for it too, but I posted something on there. If you guys didn't see, I shared a post from my personal facebook. Last week I was giving myself a haircut and my clippers broke halfway through the haircut as you can see, I shaved my head with just a you know, clipper attachment and what I always do is I always mess around with my kids, where I'll shave half my Head like I'll shave around my ears and then you know, put like a mr. t, stripe down the middle or something like that and then go ask my kids.

If I can leave my hair like that - and this time it bit me in the ass, because my clippers broke halfway through so I'm gon na share a screenshot here, real quick and you guys will see what I'm talking about. So you guys can see my screen right here and so about halfway through my clippers literally just turned off and they stopped working. I tried plugging them in they wouldn't work anymore either and my I went out and told my daughter. She thought I was joking and my wife thought I was joking too, and but I wasn't so.

I had asked my wife if she would run to Costco for me and get another set of clippers and she goes yeah and then my daughter had heard it and she want to turn this screen share off right now. So my daughter had heard me talking to my wife about it and she she thought. I told my wife that I was gon na go to Costco like that, and so my daughter was like. I want to go with you and then I started thinking about it, and I said why not so I took my daughter with me to Costco, with my hair like that and decided to go ahead and bag up the Clippers and try to return them.

And I my daughter thought that was gon na, be the funniest thing in the world and she wanted to film it. So I figured why not I let her you know go. I wouldn't live on my my personal Facebook account and let all my friends see me trying to return and all the people's reactions. I thought it was pretty funny so, but it's just one of those things where you uh, you think you're gon na play a joke on your kids and then that one bit me in the ass because the Clippers broke right in the middle.

So I got to go to Costco with my hair. Looking all funky like that, so anyways alright. So you know the the video I want to address some comments that I got on the video for the delfield region that I posted on Friday. You know I got quite a few comments from people saying you know that you know geez how come that took you.

So long I'd have been done in ten minutes or know how to change that control and moved on. If you guys haven't noticed already, I take my time when I do stuff. I take my time because I like to make sure that things are getting done correctly. Okay, I'm not saying that someone who does it fast doesn't do it correctly, but I like to take my time and make sure that things are done correct, and I stress that to my employees and the people that train with me and the people.

That call me and ask me questions or email me and ask me questions the same thing. Take your time. Do it right, get it done correctly and then you know you're not going to get a call back, there's nothing worse than callbacks. Okay, callbacks drive me nuts.

So to the people that were saying that I took too long on that call first off. I think that call only took me like an hour and a half okay, that's not too long, but even still you know, I don't care, because I'm gon na make sure that when I leave that job that that box is working correctly, I'm gon na check everything. I'm gon na you know look at the big picture, like I always say, and evaluate everything. Okay, so just wanted to address that one real quick, I'm sure you guys most of you.

People probably don't feel that way, but just address that on onto the ice machine that I uploaded today, that was another one, we're taking my time and going through everything really paid off, because if you guys haven't watched the video that I uploaded today, it was about A hoshizaki ice machine that was the complaint was that it was leaking water and when I arrived, the unit was frozen up now you know Hoshizaki, freeze ups, they happen a lot of people. Just you know D ice it and move on, but I looked at it and I went through everything and I found a lot of problems. Okay, this happens to be a new account for me. Well, at least this location Wow cm HVAC are thank you very much, but I really appreciate it.

Man says he's not watching tonight, but he sent in a super chat. That was really cool, so you know that, like I said on this ice machine one, this is one of those ones where it paid off. Okay, I I defrosted the ice machine and then I stepped back and I looked at everything and, as you guys saw in the video, I noticed that someone had written on there. They change the evaporator last year or earlier this year, and then someone had written on there that they changed the water inlet valve last year.

I also saw some notes on there about a bin thermostat that had been replaced. Okay, people weren't taking their time and looking at things what I ended up finding okay was that the first off the water inlet valve that the previous company installed was the wrong size. Water, inlet valve. So I'll be honest with you.

I think that that might have again I'm trying to guess what happened in the past. I wasn't the one that changed the evaporator on that machine, but I have a feeling that that evaporator was never well, I should say, should not have needed to be replaced. I believe that someone didn't catch the fact that the water supply line coming to the machine was the wrong size, okay, which I found and then also put the wrong water inlet valve on the machine which caused the water flow to be too low for that machine. The gallons per minute, if you guys saw in my video I I think that when I changed the water inlet valve to the right one, I think it doubled the water flow, but it still wasn't correct.

Okay, so I'm still working with the customer to get the plumber out there to go ahead and change that angle stop valve on that. But that was one of those things where I took my time and I went through everything and found that you know found the the problems and I believe to be the root cause of all the problems from day one okay, it's very interesting. I've been kind of lucky - and I guess you guys have been lucky too, because these videos that I've been making a lot of them have been at this particular it's a restaurant chain, and I picked up like four more new restaurants in my area and a lot Of my videos have been at this, these four restaurants, because it's just been insane the stuff that I've been finding that the the sloppy work, the people not taking their time to do things right, okay, the people, you know, that's why you know, I stress to my Employees, it's you've got to take your time. You got to go through everything.

You got to make sure that it's working correctly, and I even stress to my employees. Excuse me: sorry, if you guys heard the other that uh you know, I don't even care, if my guys take too long, all discount the customers bill so long as it's not excessive I'll discount the customers bill. You know if, if they took too long just trying to wait for something to come down to temperature most of the time, that's billable time. But if my guy calls me my guys are honest with me and they come up to me or they'll.

Call me and say: hey, look, you know what I spent some extra time going through this thing, I'm cool with that! Okay, even if I feel that you know we'll go ahead and discount the customers time, but my employees always get paid for their time. But you know I'm. I would rather be thorough and made sure that the job is getting done right then be half-ass and get serviced, calls or get callbacks. Okay, that's what drives me nuts.

So we try to eliminate that stuff is, is you know, and by by being thorough, you know we we do eliminate that stuff and then also to when we take our time and we go through everything we find the problems. Like I found on this ice machine. You know just stepping back and watching the machine make ice. Typically, when I'm working on an ice machine, I like to watch it make ice even after I fixed it two to three times: okay, Hoshizaki x'.

That can take a little time because in the middle of the summer, when it's a hundred - and you know ten hundred and twenty degrees outside, you might have a 40 minute freeze cycle. And that takes a long time. But again, even though it's going to take a while, that's just how I work and if you know my customers are cool with that, because they know that I try to take care of their equipment and I try to make sure that things are done right. There's nothing to you know.

There is a technical side to my videos, but a lot of the stuff that you guys, if you haven't already noticed a lot of the stuff that I'm preaching is ethics and customer service skills. You know just thinking about the customer, something as simple as when you're de-icing a walk-in freezer. You know the thing I show it every single time on. My videos is, I stress the way I run the water hose to my walk-in.

I make sure that it's not you know kinked everywhere, and you know I don't want the customer tripping over the water hose it's already an inconvenience for them. That's the way that I see it, it's an inconvenience for them that I'm there working okay and it's an inconvenience that I'm running a hot, a water hose through their restaurant. Okay, never where the customers are at, but always in the back. So I try to make it you know, as discreet as possible.

Tuck the water hose under the shelves make sure that you know where, where the customers have to step over at minimal. You know it's things like that that I think separate me from the next guy and I honestly believe that, if, if you guys don't already do things like that, I think that if you guys start practicing that kind of stuff that it's gon na make you different From the next guy also - and it's gon na make you one step better, okay right now, I think we're we're kind of well. We know that our industry is hurting for technicians right now, but, what's even worse is is our industry is hurting for top-notch quality technicians Wow. Thank you very much guys.

I I don't do these so that you guys do super chats. I really appreciate that it's Axl Marr, I don't know how you pronounce that, but thank you very much. I really appreciate you doing that super job and I totally lose train of thought when I see that come up, but you know, I really think that you know. That's gon na separate you from the next guy too, and make you a better tech and make you stand out to the customer one of the complaints.

You know one of the common complaints that I get even about my technicians that work for me is that they're not me, and I try to explain that to my technicians and it's not that they're doing something wrong. My guys know what they're doing they're good technicians and they can fix things. It's just that. My customers have gotten so used to my personality and the way that I deal with them and the way that I appreciate them that they expect that from my employees too, and that's not unheard of Wow Joe Shelby.

Thank you very much. Man really appreciate it. You know so I see that keeps like you guys are distracting me with these super chats come on. No, I have really appreciate it, though guys, but you know, that's a struggle that I have with my employees is, is getting them to to to be me essentially because that's what my customers want? Okay and don't take that the wrong way, I'm not trying to sound conceited or gloating about things.

It's just you know my customers are used to me and I honestly think that the thing that separates me from the next guy is my customer service skills. In the way that I systematically fix things and think about the big picture - and you know I - I think that if you guys use those practices that you guys would start to notice a big change too. Okay, I understand that that your companies are in a rush and they have other places for you to be. Don't get me wrong guys.

You need to listen to your service managers. You need to listen to your owners, your supervisors, your dispatchers whoever's. You know talking to you on the phone, you need to communicate with them, but if, if I were you, I would suggest calling them and saying hey, you know what this thing is a mess and I think I'm gon na need some extra time just keep them In the loop you know, as an owner there's nothing better than my technicians, calling me to say: hey bro. This is what I'm finding and it's gon na take some more time um.

You know what that helps me because you know, then I have an idea. What's going on, then I'm not on the other end of the phone wondering okay, I haven't heard from them in 45 minutes. What is he doing? I don't want to bother and that's the last thing I want to do is call my technician. Every 45 minutes.

I don't want to do that, but I do need to kind of have an idea what's going on so if he calls in and checks in with me, then it's like hey great. I really appreciate that. Okay, so I would suggest you guys consider doing that to communicate with the office. You know, I, I think we're noticing a trend here that you know one of the most important things we can do with the customer is communicate and the same thing with the office or our bosses or managers or whatever is communicate.

Call them keep them in the loop, let them know what's going on. Okay, so that's enough on that rant guys. I want to start addressing some of your guys's questions, so if I missed anything, you know throw them into the chat right now. I'm gon na start.

Looking through these and seeing what you guys have to ask, I will say that I'm sure you're already in here you had asked me earlier. Let me go back up to the top right here and it's Ralph Holly Holly Lee, I'm sorry. If I butchered your name bro, but you were asking me about refrigeration, thermistors and how they work and how to diagnose them first off, I I think I understand what you're asking me. Your question is, as you were, asking what kind of thermistors we use in refrigeration, whether it be PTC or NTC.

I believe that's what you're asking me the most common thermistor that we use and I'm not saying that we don't, but the most common thermistor that we use in our industry is the NTC. The negative temperature coefficient thermistor, okay, you're gon na find those in thermostat zone. Sensors you're gon na find those in reaching cooler sensors, that's the most common type that we use. Okay, and it's pretty simple to understand the difference.

You have a positive temperature coefficient and you have a negative temperature coefficient sensor so on the negative temperature coefficient sensor. When the temperature that it's sensing rises, it does the opposite, the resistance value drops. So that's on the NTC, so it's a negative temperature coefficient. So in my head, it's easiest to think that negative, it's going to drop when the temperature rises and on the positive temperature coefficient, sensors or thermistors, the temperature is going to increase and the resistance is going to increase.

Okay, I'm not saying that we don't use them at all. We do. I do know for a fact. I don't know a lot about the PT, the positive temperature coefficients, but I do know that they use them in motors, but the NTC, those are the most common ones that we use.

Okay. So what you would need to do is lean on the manufacturer of, let's just say, you're, using a Honeywell zone sensor and they're gon na give you a range of temperature at which that sensor is going to do this or that okay, so you always want to Lean on the manufacturer's information and read that and then you'll understand more on how to diagnose them, but essentially you know you have, as the temperature drops on that NTC or on that wall sensor, your resistance is going to do you know whatever it says it's going To do so as your temperature rises, the resistance is going to drop and, as a should say, yeah as it rises that the resistance is going to drop and as the as a decreases that resistance is going to rise. Okay, so that's on the NTC, so hopefully that answers your question on that one I would, I would suggest you do a little more research online and you can learn a little bit more about that. Just look up, NTC resistors or PT seeds.

It resistors and you'll. You'll see all the information about them. Okay, so I'm gon na keep on going down here too and see what else you guys were asking me in here: hey, I want to go ahead before I forget. I want to point out that.

Let me find him in here right now. If you go down down in the chats isaiah's in here, his YouTube channels, HVAC with Z, si s, okay, he's actually gon na be doing a live stream after mine's over he's gon na be doing a giveaway. A few guys have already entered if not go over to a isaiah's channel and check it out. Okay, he's a good kid he's new in the industry and give him a break.

You know, give him a shot and check out his channel okay. So again, when this live stream is over, Isaiah is gon na, be starting one at 9:00 p.m. Eastern and he's gon na be doing a giveaway. I believe, of an s man, manifold, right, Isaiah, if you're still in here, so give him a shot before.

I forget. Okay, guys so I'm gon na go ahead and come on up here back up at the top and keep going through these these questions here and see what you guys have. Okay, let me keep going through here. I want to say that if he, you know, I'm really blown away with the the questions and the encouragement and different things I'm getting from no joke all over the world, which is awesome.

I get people from all over the place. Sending me messages, I even get people sending me messages in other language that I have to hit. Google Translate for it to see what they're saying, which is really cool so and I'm gon na try. I think I said it on the last one.

I'm gon na try to keep doing these live streams Mondays at 5:00 p.m. Pacific Standard Time. Okay, Adam eater had asked me information about rack systems and I kind of addressed it a little bit in the chat. I don't do any supermarket rack work.

I would suggest you two people that I see actually there's three people that I really see very commonly talking about RAC, refrigeration and that's Joshua Munk see him on Facebook and the HVAC school group. Now I'm drawing a blank here. Kevin compass see him on Facebook in an HVAC school group and then Jeremy Smith. All three of those guys are constantly asking or answering people's questions about supermarket rack, work and stuff like that.

So if you guys have questions or Adam, I would suggest you lean on those guys. They seem to be very, very nice and they seem to answer everybody's questions. Okay, so they're great with knowledge when it comes to your refrigeration stuff when it comes to the supermarket stuff, but in general you know they're they're, very smart guys, so I would lean on them for the rack questions: okay, because I'm not gon na be able to Answer any of those questions I do what the small refrigeration racks, but nothing big, just the small little multiplex racks. You know that that run on the systems that run like restaurants and different things like that.

Okay, so I don't get into the big giant stuff. So I'm gon na keep on going down here through here. Let's see I see I have someone on here from Argentina right now. That's really cool Lee Rooney, I'm glad that they help you when you're in school.

I hope that you guys aren't trying to use these videos. I really appreciate the comments that I get from people that are in school, because I honestly believe that you still need to go to school, even though there's lots of great resources on the Internet, the videos aren't great and aren't enough for you to to learn so Keep it up keep going to school, I'm going down here, guys, okay, just looking for the questions here to see what you guys have: okay, I'm just gon na to the top okay. Let me I'm sorry scroll down to the bottom, and let me just answer these questions. Okay, okay, uh, Jo 65.

You asked: how long does it take to become an HVAC tech um? You know it depends on where you're going or where you're working at realistically. I think it's gon na take about two solid years of school. What you could do is, I would suggest, going to night school and trying to get a job as an apprentice or a helper while you're going to school. That's that's.

How I like to hire text is people that are actually you know already showing me. You know if they come to me and say I'm interested in this trade Ralph Holly. Oh thanks again, bro. If they come to me and say that they're interested in the trade there's nothing better than showing me by already being enrolled in school, that's that's the biggest thing.

If you can go to a company and say hey, I'm really interested in working for you and I'd. Like an apprenticeship or I'd like to work with you - and you show me that you're already in school, that's gon na give you one up over the next guy. So I think that's a great thing I think getting enrolled in school. Now I will say that you know a lot of the community colleges and trade schools are lacking, but I still think that they're important - I I wouldn't suggest it you know not to any education - is better than no education.

Okay - and I don't want to talk trash on trade schools and different things, but you can go to a community college and get a great education. You don't have to spend 30 grand to get a community college education. You can go at night, you know, I don't even know it's been so long since I go, I went what is that like three four hundred dollars a unit and usually a class, is like four to five units, so you know I mean it's a couple hundred Bucks, but you don't have to spend 30 grand, so you know - and you could do it over time - that that's how I recommend it. I have a hard time with people that take out a thirty thousand dollar loan so that they can start a job making $ 15 an hour that that seems counterproductive.

There, don't you think, but I I should be careful, because I do have a lot of trade schools and different things that talk to me and I don't want to talk crap on. Am I just not really a huge fan of them? Okay, okay, HVAC apprentice. You asked how to check if the thermostat and a walk-in cooler is working properly, basically, the best way to check if the thermostat is properly calibrated. Okay, first off the first thing you want to do in my opinion, in the way that I do it is, is verify the accuracy of the thermostat or temperature control or whatever you want to say.

Okay, so you need to have a calibrated thermometer. You guys have seen in my videos. I use the fluke 52. It's a digital thermometer, it's pricey, but it's badass, okay, confirm calibration by dipping it in ice water ice water is gon na, be at 32 degrees and once you've confirmed calibration of your thermometer, then what I would suggest you do is see and where the temperature controller, That is in the walk-in turns on and off at it's even better.

If it's a digital control, if it's a digital control, it's really easy. Sometimes you can even take the like. If it's a Ronco temperature controller, you can take the sensing probe and just dip that in ice water and see if it's accurate. But if you don't have that method, you can compare your calibrated thermometer to the reading on the digital display, okay and see how accurate it is.

I'm not gon na say change the temperature controller. If you see a one to two degree, even a three degree, difference in what you're calibrated thermometer says versus what the digital temperature controller says, oftentimes, in my opinion, the digital temperature controllers, I'd say one of the downfalls ISM is there. The displays on them are a lot of times visible to the customer and they don't always read to accurate temperatures. So that's where I tend to see a problem.

Is the customer looks up at the digital temperature controller, that's on the lock and and says hey that thing's reading 43 degrees. But when you put your calibrated thermometer in there, it's actually, you know 39 degrees in the box, so sometimes on some of the newer ones. They actually have an offset inside the control, just read the manual, and it will explain to you how to adjust the temperature sensor to reflect the correct temperature inside so basically on some of them. I know on the Johnson Controls or the pen.

I think it's a 419. I believe you can change the offset of the control, so you can, you know, calibrate your thermometer, compare it to the the temperature controllers digital reading and then you can adjust accordingly to make the display read what you want it to read. So that's pretty cool now so then you can adjust accordingly. Sometimes that's! Why, when I install the the Ronco, I prefer the Ronco digital temperature controllers.

Those are the ETCs, like the one four one: zero: zero: zero that one's a NEMA 4x multi, full temperature controller. It doesn't have defrost or anything fancy in it. It's just on-off but um. I prefer that one and usually I'll put them in a place where the customer can't see him.

I would still like to see it, but I put it where it's not super convenient for the customer to see just because I don't want to get those nuisance complaint calls because the you know they think that it's temping higher than it is. But if you can't like on the Ronco, you cannot adjust those you cannot set the offset on the control. So what I will do a lot of times is just adjust those down two or three degrees, but it's important to pay attention to the trends of your temperature controllers. If you see that on the digital ones, you know just make a note of it, write it on the box somewhere.

If you have to adjust it a degree or so and then you come back a month later and you have to adjust it another degree and then a month later, you know you get. When I'm going there's a trend there, then I think something's going wrong with that control. But if you install it from day one and you notice that's three degrees off yeah, it's probably okay, alright, as far as how to adjust like the the mechanical temperature controllers, those ones are a little bit trickier. I would suggest using - and I'm talking about like the the Johnson control or the pen, a nineteen controls.

Those are the old mechanical ones, with the copper bulb that you put in the air stream, those ones right there. I would suggest watching what it turns on and off at and comparing that to yours, you there is other ways to do it. If you, if you can understand the logic of the controls, you can turn it and listen to when it clicks on and off and do it that way, but I'm not going to get into that on this video, because I don't want to confuse anybody on that. So, but as far as verifying that they're accurate start with an accurate thermometer that you've calibrated, I really suggest you guys consider the fluke 52, if you guys can put into your tool budget.

That is an amazing tool. The reason why I, like the fluke 52, the best is because you don't have to take the battery door off to adjust the calibration. So when you're, when you're checking the thermistors and ice water or the k-type thermocouple, you don't have to you, don't have to take the back off and try to adjust it and look back at the front of the screen on the fluke. 52.

You just hit setup enter and it goes through and you do it from the front screen and it's just so much easier, and I find that to be so great. I've had other tool manufacturers tools, such as the field, piece ones and different ones where you have to take the battery door off and adjust a little point, ometer on the back and yeah. Those are a pain in the butt. So that's just my opinion, so Adam eater you're asking if I see a text shortage out here in California.

Yes very much so do we see a tech shortage out here very very much. So it's really bad. So alright gon na keep on going scroll down to the bottom. Here e of ela, you ask how accurate the field piece s? Man 4 60s are, in my opinion, yeah they're accurate when calculating superheat.

But the same thing goes for your field. Piece probes for any test instrument you use is you need to make sure it's calibrated every single time you take that k-type thermocouple on your field piece s man's, I shouldn't say every single time I calibrate mine every 2 to 3 days. Ok - and it's also very important - I've said it many many times in my talking on podcast I try to get this out to everybody is verifying the accuracy of your tools and also understanding that a k-type thermocouple, which is the type of sensor that a field piece S man's use is calibrated purport on that instrument. Okay, so let's say you have your t1 port or your your suction line, clamp.

Okay! You have to keep that same clamp plugged into that same port every single time you use that or you have to recalibrate the entire tool. Okay, because when you, when you calibrate your k-type thermal couples, what you're actually doing is you're adjusting the. Let me see if I can get this out right, you're adjusting the way that the the SMAN sees the tool okay or sees the clamp. Essentially, I don't know why I can't think of the right words right now, but you need to make sure that the the suction side clamp is plugged in to the T or the suction side terminal every single time.

So I usually mark on mine and I'm sorry. I can't think of the words to say what I want to say right now, but you need to make sure that it's plugged in to the side that you calibrated in every single time. Okay, so let's say I calibrate my SMAN clamp for the the suction side. In terminal t1 on your your SMA engages you dip it in ice water, you adjust it down to 32 degrees.

Okay, then you, you put your gauges up when you're done and you go to use them tomorrow. You need to make sure that that same clamp gets plugged into that same terminal again. Okay and again, even still, I still calibrate mine like every two to three days. Okay, verify calibration and make sure that they're accurate, but yeah they're they're, very accurate.

Another thing that people neglect to do is when they're taking their field piece, k-type thermocouple, the the suction side, clamp. I would suggest that you sand down the pipe that you're gon na put that clamp on, because the accuracy will be increased when you sand down that pipe. Okay, that's another thing that I think it's forgotten about and if you guys use the the new field piece, Jobling probes you'll realize that the new way that they're using the their clamps is you have to sand down the pipe, because the the way that they're reading The temperature on that the surface of the pipe it has to be sanded down for it to work. If you guys have used those, you know what I'm talking about when it beeps and different things at you.

So but yes, they're, very, very accurate you'll. Please make some great great products there s. Man 460 is amazing, okay and yeah. Just uh! That's all I'm gon na say about that.

Before I get myself in trouble, just keep an eye out for field piece. They got some new stuff coming. That's all! I'm gon na say: okay, all right. Let me keep going down here guys.

I there's a lot of questions in here and I'm sorry if I'm missing them, I'm trying to to go back up, but then every time I laughter I get done talking. I look back in here and there's you know ten more, so alright keep going. Do I do I like the testo gauges or testo clamps all right. I can't honestly give a fair review on the test O's because I've never owned them.

Personally. Am I gon na? Go buy some no and I'll, be honest with you. They don't look to be the greatest to me, but that's not fair for me to judge them because I've never used them. Okay, I just just not a fan of them, but I know a lot of people that really really like the testo gauges and the testo probes and different things.

I think that I would give testo a better shot if they increase the Bluetooth range on their probes. If they went ahead and up the Bluetooth radios and their things to bluetooth 4.0, like field piece did, then I think that they would be a definitely a competitor with I manifold and field piece and different stuff. Okay, but right now, field pieces cutting edge and they are they're really shaken up the market as far as when they came out with their smart probes. So you know not a fan of the test of stuff, but again I've never owned it.

So you know, I guess I got to be careful about that. So don't you know if you think they're cool, I could I'd say, consider trying them out the price point on their test. Oh smart probes is amazing. It's much cheaper than the field piece ones too, but I think you kind of get what you pay for.

So all right, keep going in here guys bear downs that hurts bro. You lost your fluke, fifty-two, damn yeah, I want to say it cuz. I just bought another fluke 52, because my other one finally wore out after, like five years, lasted me forever. It got to the point that the I still have it: the k-type thermocouple x' they're, loose they've, been plugged and unplugged so many times that they're loose inside the the ports on the top, and so I finally broke down and bought another one.

And I knew they were expensive, but damn I want to say that thing was like four hundred and fifty bucks. It was nuts for a thermometer, but it's worth it in my opinion, definitely worth it. In my opinion, all right, gon na keep going down in here. Real quick, okay, see what your questions are right here guys do.

I use any Hill more tools? No, not really. I always was interested in their hydraulics wager, but the price point just scared me away. I onson honestly had thought about buying the hill more hydraulics wager for about a year or so, and then they came out with the the swage tools for spins wage came out with their swage tool for the drill and yeah. I no longer needed that hydraulics wagerer anymore, now that I've got the swage tools for my drill and yeah no need for it, but no nothing against no more tools.

I've heard good things and bad things so bare downs. No, you can't go wrong. A fluke fluke makes great stuff, but I will say the price point of some of the field. Piece stuff in my opinion is blows.

Fluke out of the water. Now is the accuracy of the fluke stuff better for sure you know, I mean fluke, makes a high quality product, but, for instance, I have my field piece. I think it's the SC 660. I believe it's like the fully loaded, clamp meter with all the bells and whistles, and it has a phase rotation in it.

So you can check line 1 line 2 and line 3 to see if it's. If it's set up correctly that meter, you know buying everything that comes in that meter from fluke is gon na cost. You thousands of dollars, because fluke doesn't make one tool that has everything that that fully loaded field peace meter does. But I do understand that fluke has a better tolerance when it comes to measurement accuracy and different things, but for what we do that field piece 660 is, I believe it's a 660.

Hopefully I'm not butchering that number, but um that that field piece 660. Is it it's amazing, you know yeah it's a big meter, but if you do what I do service and then some installation and startup that 660 is great, because I can keep one thing in my bag. Yeah, it's a little bit bulky, but you know I don't got to carry four different meters with me. I don't have to have a phase rotation check or you know all these different things.

So alright, but I do appreciate fluke stuff. Okay, if you guys have seen my tool, bag reviews and different things, I keep a fluke. I don't remember which one it is dude, it's it's a fully loaded, clamp meter that has the flex, cable and all that fancy stuff. I keep that in my my little troubleshooting bag and then I keep the field piece in my you know: veto tech pack, so I I carry you know one when I'm doing troubleshooting and then one in my big bag.

So I like them both alright keep going up here again, yeah field pieces. Ixora fluke is expensive, but you know you get what you pay for guys, so Brian Carly yeah again, I'm sorry guys, I'm like jumping into the questions here and butchering, or you know, miss and other stuff, Brian Alcatel I'll hold up just a second I'll I'll get You a question here in just a minute. Okay, let me answer this other one Brian Carly. She has the amp Pro 52 a decent product versus the more expensive fluke.

I honestly don't know the amp Pro 52. I think I need to to research that, but is it isn't amp pro or amp, I'm assuming that's amp probe right is an amp probe the same as fluke. Aren't they just like a knockoff or whatever I'm going to look it up right now, amp Pro 52 see what we see here, I'm assuming it's supposed to be probe because it's not coming up amp probe 52. Ah, that honestly looks like the same thing: bro.

Never even knew that thing existed, Wow yeah guys. I would consider checking out the amp probe 52 because it looks identical to the fluke and it's like a hundred bucks thanks buddy made me realize that I spent way too much money on a tool. No yeah. I don't know I've never used it.

It looks great, though I might buy one just to try it out, because I'd give that, to my guys that looks great I'll definitely have to check that out. Okay, um! Let me go down here. Someone had a question about a hoshizaki bin thermostat. Let me try to find this again real, quick, look in here, guys Bryan.

How could I hope I'm saying your name right is ah Katella. I hope that's correct. Okay, I'm gon na try to find it here. Real quick, let me find this Hoshizaki bin thermostat question.

Bear with me guys kind of going through the comments here. There's a lot going on. Well. Is this going way up? Alright, I think I might be missing it hold on there.

We go. Oh okay. Does the same principle apply for the push style Bend step from Hoshizaki, okay, Bryan um, you know no! So the bin thermostat timing, it that's! Actually, if you, if you open up the Hoshizaki tech specs book, that's the orange book that tells you about the machines. It tells you the process, it tells you how long I think it's like they want for some reason.

I think they want the machine to turn off within nine seconds and then on within six or something like that. That's the thermostatic bin, thermostat, okay. So that's a gas charge bin thermostat. It reacts just like a normal temperature controller or mechanical temperature controller as far as the the paddle style or button style hoshizaki.

That one is a it's a magnet style, I believe, and no that one's not a time to issue. I believe that it has to see it within so much time within a certain time period. It has to see that thing closed or open, or something like that. I'd have to read in the book.

I'm gon na be honest with you, I'm not hoshizaki is going to that that new style, the button style Ben thermostat and I'm not a huge fan of them, because one of the biggest issues that I see on those things is the calcium gets behind there and Messes up the the button and they don't get cleaned or not enough and they cause a lot of problems. So Ness Ness, you $ 100 sounds like it might blow up in your hands yeah, but it's only sensing temperature. It's not sensing voltage so pretty as long as it's reading the accurate temperature I I'm gon na buy one of those just to try it. I'm gon na yeah and check that out.

Maybe I wonder if Zak I don't think you're in here Zak, but you you don't get any like props. If we buy a tool and mention your name from amp probe, do we? I know you, your amp probes, one of your sponsors, maybe I'll reach out to Zak and see if he gets any credit or something like that. If I say that he told me to go, buy that but um or maybe even we can get Zak to review. One of them, because I bet you they'll - send him one of those yeah.

Maybe we'll do it. Maybe I can get Zak to send me one and I'll review it for him. Hey there. We go Zak if you're watching see.

If you can get me one of those ant pro tmd 52s, if you can't I'll, buy one, no big deal, it's a hundred bucks, so not that a hundred bucks doesn't matter, but that's worth it. The amp Pro the AM 560 D mm, will dual dual temp. Okay, yeah, a dual temp, I think, is better because that's what the fluke fifty-two does or 52 2 or whatever yeah it does yeah I'm gon na I'm gon na buy one of those and try it out thanks for pointing that out. Okay, Brian yeah you're working on a cam 1301 I'd, say the biggest biggest things on those ice machines.

Man is the the calcium and water flow you guys saw in. My video, you know, is just someone change the water valve and put the wrong water valve in there. So all right mm guys, I'm sorry, I'm missing some of these Rick. You said that it's made in China, like the Fluke 376 is.

Are you talking about the the the amp probe 52? I haven't be surprised of everything it's made in China anymore, guys so yeah I'll. Look it up critical! Think I don't know if, if the, if true tech tools has that, but if they do I'll check it out, yeah or maybe I'll get, maybe maybe we can see if Zack can do a review on one or something you know that'll give him some credit too, But yeah I'll check that out yeah. I would all you know: there's lots of people. Okay, no worries, Rick, all right Ulysses here, man yeah! Isn't it funny how you know the Dozen Black & Decker owned craftsman now tool? I think Black & Decker owns everybody.

They owned a wall, they owned craftsman, they owned ill more, they own Lennox, believe they own everybody. Don't they. You know it's funny, how the small crappy tools that we used to hate. Oh Stanley, there you go.

Okay, Stan little Stanley, Black & Decker. It's all the same bro right so yeah, it's all the same, yeah Rubbermaid, yep, all the same stuff. It's just one big conglomerate. You know so alright guys.

What am I missing in these questions here? Am I missing anything? You guys have any questions that I didn't answer up in the top put him down at the bottom again cuz, I'm. It takes me too much time to go through these, for you new guys that came in here. If you guys didn't already see I'm gon na share it again, I told him the beginning of the stream that uh. I had a problem earlier last week where I was shaving my head and hey Gary, and I shared it on my facebook.

If you guys, there's actually a live stream, so anyways what happened was last week I was shaving my head because I shaved my own head and I used clippers and my clippers broke right in the middle of shaving, my head and what I usually do is I Just a mess with my kids I'll shave like weird patterns in my head, so I shaved around my ears and then I shaved, like a reverse mr. t, so I put a big strip. You know racing stripe right down the middle of my head and then I was in the process of shaving the rest of my head and my clippers broke right in the middle, and so I'm gon na share my screen right now and show you guys. I showed this in the beginning, but I'll show it again so uh yeah right in the middle of shaving, my head, my clippers broke and then I had to I had anyways long story short.

My daughter wanted to return. I told her. I was gon na return. Him as a joke and anyways, we ended up going to Costco and I went ahead and returned him with my hair, like this, and my daughter wanted to put it on Facebook.

So I said: okay and we went on a live stream, so anyways. If you guys go to the HVAC, our videos, Facebook, page and scroll through my timeline, you'll see the video. If you guys have the patience to watch it, it's pretty funny to see people's reactions and I'm trying to return these in the Costco line and then the whole time. While I was in line.

Oh and that's that's the kicker that I forgot to mention in the beginning of the thing was, as i was returning them, i'm standing in line and the lady's going through the the list of stuff and she's trying to find him come to find out. I didn't buy them at costco guys, so i stood in line for 15 minutes, while the lady was trying to find him for the last three years and oh yeah, my bad, i didn't buy him a costco. So then, after that happened, I got to go ahead and walk back out of costco and then go back in in the front cuz. I still needed clippers.

So then I got to buy him and go through the whole store again. My daughter, she thought it was the funniest thing in the world and I'm gon na go ahead and stop sharing this now, but she thought it was the funniest thing in the world and it doesn't bother me. I don't care if you know people see me like that, so alright, so I just wanted to tell that story again. So yeah, like I said, go to the HVAC our videos, Facebook page.

Earlier this week I shared my from my personal facebook page. I shared the video of me returning them to Costco. We were like live on Facebook and that's pretty funny. Okay, so I see some questions come in here.

What would be a good pressure for 410 on an a/c unit? You live in the Bay Area, okay, Edgar. Here's the biggest thing bro, let's not talk about pressures. Okay, we need to talk about temperatures. If you understand how refrigeration works, we work in saturation temperatures, okay, so pressures there.

You know, but it's more important, to look at our saturation temperatures and understand what your saturation temperatures should be. Okay, excuse me: a climate doesn't really matter so much as the the type of equipment that you're working on the seer rating is gon na affect your evaporator TD and your condenser TD. So what I would suggest is is leaning on the manufacturers to find out what kind of equipment you have if it's an old 10 seer. You know you might be running a 35 degree.

Evap TD, you might be running a you know: 15 to 25 degree, condenser TV, it's it's all relative, so you need to understand and and know what your saturation temperature should be before we just tell you a pressure. Okay, and if you guys understand you know, if you don't already understand, everything's gon na affect your saturation temperatures, you know the humidity outside the humidity inside everything. So let's not talk about pressures. Let's look up what kind of equipment you have and then you can evaluate it any more you're, more than welcome to send me an email and we can talk about it more HVAC, our videos at gmail.com.

Okay, all right! Let me keep on going down here. Cain. Iva ster. Mister.

Sorry, if I'm butchering that you asked if they make us, use the K flex for refrigeration lines exposed to the Sun, I don't understand what the K flex is. Is that, like the the white painted insulation or whatever, like the UV resistant insulation, I know that there's like a code for my area for different stuff, like that, where they want you to use UV depending on the township or city that you're in they have different Rules and different things, but I honestly don't know what K flex is: I'm assuming it's the the Sun, resistant or UV resistant insulation and yes, we are supposed to use UV resistant insulation on our stuff. Okay, keep on going down here, guys water, cooled condensers on ice machines, what to always check and what to keep in mind. Ralph Ali Ali Li, sorry, bro, okay, um again, I'm gon na suggest you lean on the manufacturers, but your your condenser TD is gon na.

Be a big one dude I I'm very cautious about throwing numbers out, but for some reason a 10 degree. Condenser TD is sticking in my head right now, but I would suggest you download the manufacturers information and find out what your TD should be understand. What a fouled condenser is a fouled condenser on a water-cooled system is when your condenser is got so much calcium in it that it can no longer reject the heat or, or I should say yeah. I guess, reject the heat of the refrigerant.

You know into the water so understanding your TD is going to tell you if your condensers fouled, you know, and it all depends to on you know we don't see a lot of water-cooled ice machines out here anymore, because they're so concerned about water usage. Most of the time they were dumping that water into the drain. I think all ice machines that use water, cool, they're, just dumping the water and they're, not a real fan of us dumping water here in California, because we are limited on our water resources. So don't have a lot of experience with us, so I'd suggest, leaning on the manufacturer, so alright gon na keep on going through here see if I'm missing anything low pressure, control cut in and cut out for r22 Thomas M you're asking me okay.

So it's very important to know what kind of a system you're working on if you're working on a walking cooler, that's a pump down system, then you're cut in and cut out are typically gon na. Be you know, I I would say I like to see my the differential between the two, usually about 20 to 30 psi, and my cut out is usually gon na, be depending on the refrigerant and the compressor that you use and in the system anywhere from five To 15 psi for cut out okay, but you can all if I think I've had some videos on this. You also have to understand that sometimes we can also use a low pressure control as a temperature safety device. Okay, so we can set up a low pressure control on a system to make sure that it'll cut out when the box temp gets too cold.

Okay, I did. I think I did it with a podcast with maybe I talked about it. I wrote an article for Brian or about different temperature controllers. I think I did it on the podcast too, where we can actually use a low pressure, control, understanding that there's an evaporator TD and the suction saturation temperature of the gas.

We can use that low pressure control, you know and basically predict or know what our evaporator temperature is and therefore, if we know we have a 10 degree TD on our walk-in cooler evaporator, we can say at this box temperature. My pressure should be this much okay and again. I I'm not going crazy into detail on this, so hopefully I'm not confusing you, but basically I can say that if I have, if I know my TD on my evaporator coil and my box is at 40 degrees I'll know exactly what my pressure is and I.
