Hey everybody: how are you guys all doing this evening? Hopefully you guys can hear me. Okay, I apologize for not being here last week and I realize I planned on putting a notice up to say that I wasn't gon na be streaming last week and you know stuff happened and I was on a plane. Couldn't but oh well, sorry, but I'm sure you guys will live a couple things I want to cover. The first thing I really want to address real quick is that I am way behind on emails.

So there's there's like a backlog of emails and I will get to them guys, I'm trying I will you know, try to get to them as fast as possible, some of them I'm gon na address in this livestream, for you guys and then you know we'll get To it all, but you know so just be patient with me and I will get there thanks so much for the super chat Zack. I really appreciate it and you know let's get on with it, so I'm just gon na start addressing some questions. I had a really good question this afternoon. Actually, so I'm gon na put that one in front of the other ones, because it's gon na kind of cover some really important topics.

Forgive me, I did not write down the person's name, but you had asked me a question about line sizing and he was talking more on a residential setting. He was doing a walk-in cooler for a high high dollar residential walk-in cooler. I guess I should say so, and he was kind of curious about sizing the refrigeration lines, whether it be the liquid and the suction line for the system. Okay - and he was asking me - you know, how do I go about that? The first thing is, is that remember, and I'm gon na stress this to everybody right now - is that I am just a service technician.

Just like you guys, okay, I just do a lot of research and look into things. You guys also have the ability to, and I realized that a lot of people don't know where to look, and so I have no problem pointing people in the right direction. Okay - and this person also specifically said he didn't want me to size the lines for him. He just wanted me to push him in the right direction, so you know when you guys do ask me questions.

You understand, I'm just a normal dude. That makes the same mistakes that you guys do so you know take it with a grain of salt. I guess you can say okay so, but when it comes to sizing for refrigeration systems and we're talking about walking, coolers walk-in freezers, even remote prep tables and different things like that, okay, it all you have to take into account the pressure drop on the system. Okay, the pressure drops the biggest issue and you, the the the next thing is, is that we want compressor cooling from the suction gas coming back to the compressor, and we want proper oil return coming back to the compressor, so we have to properly size our lines.

Accordingly, okay, we have to add oil traps or P traps to help get oil back to the compressor. If it does leave the compressor in a perfect world you're going to design a system that has oil separators built into it, so that the oil really never leaves. Okay, but on the flip side of that, if you design the perfect system that has an oil separator and doesn't allow oil to leave the condensing unit section ever then, potentially you could run into problems with your expansion valve, because you do need that oil to lubricate. The components in your system - okay, so that's another thing too, but realistically you're never going to make a system so tight that it's never going to lose any oil okay.

But when I'm sizing lines, what I'm going to do is I'm going to start by leaning on the manufacturer. I say that with everything, okay, I'm gon na communicate with the manufacturer, and I'm going to you know, ask them what their opinions are. Okay, it's very very important to do some research, though, and understand when, when we're talking about line sizes where you're gon na hear a term called total equivalent length. Okay - and we also use this term in ductwork design too, but total equivalent length takes in the total length of the lines, okay and it takes into account the let's, but if you're dealing with ductwork, we can call it the friction, loss it through your fittings.

Okay, your 90s and different things, but essentially it's the same thing in refrigeration, piping. Okay, so you know I'm pulling these numbers out of nowhere, okay, but we can say like a 7/8 inch 90, let's just say it might have a total equivalent length of let's say a foot. It doesn't, but I'm just saying you know in general, versus you know a smaller ninety and different things, so you you have to take that into account. It might be two feet.

It might be three feet in that 90. Okay and essentially, what you do is you take the total equivalent length of all the fittings and then of all the straight runs of pipe, and then you add them up, and you come up with your total length. Then you use that calculation to to size your lines. Basically, okay, but there's there's again, I'm not pull.

I'm not gon na tell you guys how to do this, because I don't know it off the top of my head. I've only done it a few times. Most of the time in the refrigeration industry, unless you're an engineer, you're not going to be designing systems. Okay, now I will say that if you're doing like a retrofit like this guy that had emailed me - yes, you will, but you might be thrown in a suction line in a liquid line.

It's very rare on the light commercial and residential side that you're gon na be designing refrigeration lines for like a built up system or something like that. A built up system would be. You know big giant industrial refrigeration system, okay, where you're gon na have a separate condenser you're, going to have a separate compressor. You're gon na have a separate evaporator most of the time.

What we deal with in light commercial and the residential side - or I would just say, light commercial - is prepackaged units. Okay, so I'm gon na buy an evaporator. That's already gon na have a distributor on it. I'm gon na add a thermal expansion valve to it.

Okay, I'm gon na buy a condensing unit. That's a unit in itself. It's going to have a receiver, it's going to have the condenser it's going to have the compressor and it's going to have all the piping and all I'm gon na need to do is connect the liquid in the suction line. Okay, so we don't need to get crazy technical into like the liquid drain and different things like that: okay, but most of the time, what we would be sizing is just the liquid in the suction line.

Okay, and to do that, like I said, I'm gon na lean on the manufacturers and two of the biggest ones that I would suggest, or two of the biggest resources that I would suggest you look up to do so, would be the installation manual for the particular Type of equipment you're installing okay, that's the number one. Okay, I deal with a lot of heat craft refrigeration equipment. Heat craft has a ton of resources on their website. Okay, if you go to heat craft, our PD comm and you research, there's a literature tab.

You can click on it and you could find literature for all kinds of stuff. Okay, one of the coolest things that I found a long time ago on their website, actually as before their website was even big. It was a manual that was in a supply house. Was something called the heat craft engineering manual, the heat craft, engineering, man? I went and printed it out today because I can't find a printed copy at the supply houses anymore, but this is the heat, Kraft, engineering manual.

Okay, you can it's a document number H e ng M. Oh 408. Okay, if I was a great guy, put a link in the chat, but I'm not okay, so just go to heat crafts website and then there's a little search bar and put engineering manual. But this engineering manual essentially again is going to teach you how to do hand load calculations which nobody's really going to do anymore.

Okay, I hardly ever do a hand load calculation, but it does help you with sizing refrigeration lines, and you can use this to help. You size refrigerator refrigeration lines for other equipment too. Okay, the next thing, if, if you any of you guys that have been in the industry long enough, I don't know if they still tell you guys to have these in school, but the copeland refrigeration manuals. Okay, these things are ancient, but they are very relevant to this day.

I think these things, these things have been reprinted and you know added to it over the years, but I want to say that mine well, this is originally copyrighted in 1969 and then it's been revised and reprinted. I think on the back of it. Mine was revised in 1986, but it also helps you to cover and you can actually see this is from when I was going to school. I have little tabs right here that say different things, so this book right here was the book that I had to study when I was learning how to size, refrigeration systems, how to do load calculations and different things.

Like that a lot of times, we can find electronic software that can do it for us now too, but you know, I'm not an engineer so I'll still open up this heat craft manual to to find out what size suction line. I should use what size liquid line I should use, but you know other than that, I'm not really using it to do load, calculations or anything like that anymore. But if you buy the set of yeah, it does Jason Jason says the Copeland app has those and it's really cool, but if you buy the set it comes in a binder. It's got like I don't know, it's probably got six or seven manuals in here, but this is still a very relevant book right here that helps you to understand the refrigeration cycle and all kinds of stuff.

Okay, you know some of the pictures in it might be a little antiquated because they might be talking a lot of semi-hermetic stuff when you know we're dealing with mostly scroll, compressors and four different things right now, but I will say that you know with semi-hermetic equipment. We we had a lot of wiggle room, okay, and we had a lot of forgiveness and our equipment, and now that we're dealing with pretty much, I think Copeland's made a mandate that everything's going to go scroll even their little fractional horsepower. Refrigeration units are going scroll. Now I don't know if they have a half horsepower scroll yet, but I'm sure they will soon.

But when you're dealing with scroll compressors, something that came up, that's been coming up and getting worse and worse is they need that suction gas? Coming back to the compressor? More so than ever, to cool the windings on them and a lot of the scroll compressors, especially on the low temp. They had to do what they call a liquid injection to help cool the head of the compressor off, because they were going off on thermal overload. Inside the compressor, so that's another thing too, so you know even more so than ever. We need to make sure their lines are sized correctly to you know, get that suction gas coming back to the compressor, to help cool it off so that we don't have like a thermal overload issue on a high temp day.

If you guys have paid attention to my channel last summer, I had quite a few videos where we had like a record-breaking heat wave here in Southern California, and we were having thermal overload issues on compressors, all scroll, compressors, left and right refrigeration systems. And I'm going to kind of segue into another topic right now for another question, but this is perfect because you know we we tend to have a lot of issues on multiplex systems, okay and a multiplex system. In my my definition of a multiplex system is a single compressor running multiple evaporator coils. Okay, now in a restaurant I can think of a restaurant, where I have a refrigeration rack on the roof and I have, let's just say, ten evaporator coils, all throughout and all the different refrigerators inside, the restaurant, they're, all remoted and that's a multiplex system.

So something you have to remember a multiplex system, and this is where I'm kind of going into another another question, but it's you know kind of loss to do with the same stuff. When you have a multiplex system. Here's the problem you size, the system for the biggest load - okay and the biggest load - is going to be when all those evaporators are calling right well, when we're dealing with these multiplex systems, we're talking about little reaching coolers most of the time. Okay, so I might have a mm BTU load and wanted them, but then, when you multiply that by 10, okay, you've got a big load.

Well, so we size it for the biggest load right and, let's just say, 12,000 BTUs, okay! Well, what happens when only one of those evaporators is calling - and we are only getting two thousand of BTUs running through that coil and we're not getting the proper suction gas coming back to that compressor now this is not a situation that a properly sized line would I mean it affects it, but that's not going to solve the problem. It's not that we don't have a big enough suction line. Coming back to the compressor, it's just that it's a very inefficient design in the system. Okay, so ever more so than ever, you need the proper refrigeration line, sizes, okay, but that multiplex system, I call them compressor killers, okay, especially when we're dealing with like little reaching coolers and reach and freezers, because essentially, when we have a restaurant that has a rack System on the roof - and it's got a bunch of multiplex medium temperature evaporators in in this, the restaurants that I work in, we tend to have to change those compressors every two to three years, and you know if we had a properly designed operating system, we shouldn't Have to change that compressor! For I don't know, 10 15 years, okay, but it's because those multiplex systems do that they essentially some of them, have like a low temp load where they might be running a pan, chiller, okay and that's going to be the least amount of load on that system And there's multiple times in the summer where we might be running just the pan chiller and we could have a really high temperature outside and the compressors will tend to go off on thermal overload when there's really nothing else wrong with the system, except for the fact That you know they're only calling for a partial load.

That's also a great argument for like digital compressors. We have yet to see them really come into play in the light commercial sector dealing with restaurants. But I I have a feeling that once they make a small enough digital compressor, that's really going help. You know the the life expectancies of these systems, because if we can have a digital compressor that basically slows down when there's no load, you know, then you know.

Theoretically, that systems gon na last a lot longer, but you know, along with digital, comes a lot of problems too. So I will get into the chat here in a little bit guys and answer some of the questions that are coming up and stuff, but I'm gon na just kind of keep going with my topics right now and then we'll get to it. Okay, so yeah the the line, sizing or the other thing I wanted to bring up to about the line sizing is, is not only in heat, crafts, engineering manuals, yeah, Vincent vishton, Leslie, yeah, variable, speed, compressor would and that's what I'm talking about with, like the digital Compressors, because the digital Scrolls they can slow down and speed up depending on the load so yeah. That would help.

But we just haven't seen those come into the light commercial sector very much. Yet I've seen them on ACS, but not so much on the the big stuff. What's up Dennis how you doing, but the other thing I wanted to bring up was in you know the condensing unit manual for heat craft. Again, you can find this on heat crafts website, its heat, crafts or heat crafts, our PD comm.

It also tells you how to handle the line size and in these things too. So in this situation, if you know the question that was emailed to me was how do i size the liquid in the suction line for this condensing unit with this evaporator coil? You just have to you know, basically, just follow the instructions in the manual and essentially it's going to tell you. You know the total equivalent length and in in these manuals, these heat craft ones, it's kind of kind of generalize it and make it a little bit easier. If you follow the heat craft engineering manual, it's going to get a little technical, they kind of give you you know within a hundred feet.

Do these lines within a hundred and fifty feet. Do these sighs? You know when you get into the engineering manuals it's actually gon na you're gon na. Do the math and figure out for 66 feet how long it needs to be so. You may find that the the manufacturer's instructions might make it a little bit easier to to size the lines accordingly.

Okay, okay, TJ k. Hvac, are you said what about hot gas bypass for a low load yeah? That would help well. Let me think here yeah. I guess that would help why why you, but there's there's something about it, honestly, that I can't think of right now that creates a problem with the hot gas bypass and I'll have to try to think about it again, I'm not really.

Sometimes I know there's something that there's an issue with the hot gas bypass that creates a problem on the little systems. Let me think about it for a minute and I'll come up with that. I know there is okay. Next thing I want to cover is I'm just kind of going down the list here with my stuff, those multiplex systems, to the compressor killers that I call them you.

You will see that a lot on like a kayak, the older Kai rack systems, where they weren't running the glycol and they were just running just like normal pants Hiller's and what you'll see is you'll, see like I said liked an evaporator coils and where we see The most problems this is when just like one or two pan chillers, is calling because it's low, temp low pressure very little refrigerant. Coming back and that's when you really start to see the high temp issues and after so many times that that compressor going off on thermal overload, it'll damage the internals of the compressor and cause a problem, and this mostly happens on the scroll compressors. So, okay, I want to a drawer. I want to remind you guys about the spoilin BQ te v kit right behind me right here.

Okay, I have the giveaway going on next week next Monday, actually April 1st, it's not a joke, no April Fool's junk or anything like that. Okay, I'm really giving that kid away. It's really easy guys. If you haven't already entered the giveaway, the nightbot should be popping up the link here in a minute if they haven't - or he probably already has so you can just go back in the chat.

You just click on the link and enter your information, no purchase necessary. You know just follow the instructions. Okay, I also have a video on YouTube that explains the instructions. I'm not going to go over all that right now, but you know everybody's got an opportunity to win this spoiling B Q TeV kit, so I suggest you guys enter that.

Okay, we've only got a couple more days. I think the giveaway is going to end. I think it's like in the morning on April first and then I'll do the giveaway that evening on the livestream okay. So, if anything, I would really really appreciate, if you guys haven't already, if you would go over to spoil ins YouTube page and give them a sub and then also check out some of their content.

They have and again just follow the instructions in the giveaway thing and it'll. Explain it all to you guys: okay, oh and the other thing about the giveaway too, you guys need to make sure you confirm your email. So when you enter the giveaway there's a bunch of people in there that, even though you entered it, you have to go back to your email and you have to hit the confirmation link. Okay, if you don't hit the confirmation link your your entries not valid, so you got to make sure you hit that confirmation link guys: okay, yeah Timothy Solomon, you, the total, equivalent length fitting table, is in the Copeland manual.

Yes, okay, you can also find it in a lot of other refrigeration manuals. It's just that was the easiest one that I remembered just because I have a book marked in there. So if you look in the refrigeration manual part four system design, that's the one where it's going to show you how to figure out the fitting lengths and all that good stuff. So but yeah so make sure you guys be careful Ted I'll.

Give you a blue wrench right now, buddy, you could start banding people. Anybody wants a blue ranch. I give them out like nothing. I'm just kidding but yeah just make sure you guys hit the confirmation, email and finish the entry that way you guys get it because, like I said, there's at first I was trying to remind everybody but there's so many entries.

Now I yes so many I mean. There's 503 entries, I think, or something like that into the contest. But yes, a bunch of people haven't done the confirmation, email and it lets me know that. So you know those people will be disqualified.

Essentially when it comes time to pick the the enter okay. Okay, I'm gon na go in here and see if I'm missing anything in the chat. If you guys are, if I missed any questions, any big questions, you guys go ahead and put them down in the bottom and do me a favor and put them in caps. Locks so that way I can see them.

I'm gon na address one more inch here and then and then all all answer some questions do so ok, so another question that was coming up is about merch, okay, I I have made shirts. They are through teespring, for whatever reason, teespring was kind of being a pain in the butt in that I'll get to your question here in just one sec dude, so teespring was being a pain in the butt and that I had a hard time. Turning off the link on my YouTube page, so you guys are more than welcome to go ahead and order. The shirts now I had said originally to a couple.

People like they may want to hold off, because I'm actually getting my samples like tomorrow samples I shouldn't say that I bought like one of each shirt and I'm getting them tomorrow. I just wanted to make sure that the logo was correct. So if you guys want to hold off for another couple days, that's fine, for whatever reason it was hard for me to disconnect the link on the YouTube thing. So I just left it there, but nobody's ordered anything yet so just give it a couple more days and then you guys can order stuff.

If you want to so okay, many more, you said you have a vending machine in the evaporator. Coil is icing up on the top few rows. Could this mean that the refrigerant is low? This machine has no sight glass. So it's hard to say: okay, that's kind of a loaded question, but if airflow is going across the evaporator correctly and you're getting Frost only I'm part of it, you know that could be a refrigerant.

That's definitely a refrigerant problem, but whether or not it's low uncharged that I don't know. Okay, that's not something! I can tell you right here, but you you typically want to see more of an even frost pattern, but you know the fact that you can see the evaporator concerns me that maybe it's not getting the proper air flow across it. So you know you have to have the proper air flow going across the evaporator for the refrigerant to boil off correctly and do what it's supposed to do inside the evaporator coil, so yeah that that's kind of a hard one to answer. Okay.

But it's definitely a problem of some sort, whether it be an airflow problem or a low refrigerant charge, or something like that: okay, but yeah, typically on a vending machine, you're not going to see a sight, glass or receiver for the most part. Unless you know it, I haven't worked out a lot of vending machines, but most the ones that I worked on have been little cap tube systems, little tiny things. So, okay, any other questions pop up on there. There seems to be some feuding and disagreement in the chat room yeah.

I don't know no idea what else we got going on here, I'm going to pre-order the 480 any objections to you: ok, LA HVAC. So the estimate - that's that's actually great, because that was one of the things I was going to cover. Okay, I want to make it clear. You know I really dig the the field piece: sman 480, that's the one.

I've been doing a beta test for them. Ok, I did not purchase that manifold, but I will tell you that I've honestly earned that manifold. Ok, we myself and many other great guys all over the United States have been testing the field piece matter. Actually, not just the United States.

There's there's a dude in Europe. I think and there's that anyways there's people all over the place that have been testing their products. Ok, and it is a really great manifold. Ok, I just want to make sure that people understand that you know nothing is perfect.

Ok, the SMAN 480 is, is it has all kinds of great features to it, but there's flaws to it too. Okay, when I say flaws, I mean nothing bad, but I mean I just want people to bully. You know to understand that, like the connection on it, it has a great Bluetooth connection. Ok, but it is not a hundred percent as good as the I manifold was, even though I don't use the high manifold stuff very much anymore.

I have all their products. The range on the high manifold stuff is insane: ok because it has the ZigBee protocol for the repeaters or, and it's repeatable. Ok. So even if you don't have a range, you can throw a repeater in the middle.

So the field piece manifold, I believe, is using the Bluetooth, 4.0 or LTE or whatever some fancy stuff. It's amazing range for Bluetooth, but it's not like the badass. I manifold stuff, that's repeatable! Ok, so it does have weaknesses, but I have been using the field. Peace, stuff and I have been on a three-story building before and I was able to connect to the evaporator two stories down.

Ok, but then I've also been on a one story building and been on the roof and they wouldn't connect. Okay, so it all depends on the interference when you're dealing with Bluetooth, okay and I'm sure - maybe some of the guys in the chat can explain it to you. But there's there's a bunch of technical jargon and stuff like that. That goes into interference and different stuff.

With Bluetooth, okay, but in my opinion, if, if I was to go, buy a new manifold today, if I'm looking for a manifold heck, yeah, I'm gon na buy that field PC either the SMAN 380 or the 480 that will be coming out. I'm told here anytime in April, okay, so yeah definitely I would buy it. Okay also need to make it completely clear, because everybody always sees me using the the field piece manifold with the wireless clamps. Okay, it does not and will not come with the wireless clamps.

I'm sure that maybe some of the tool companies will make a kit that comes with the wireless clamps, but further like I think it was like for. I think it was more like 500 $ 600 price range of the manifold. It's not going to come with the wireless clamps. Okay, it's gon na come with the normal k-type thermocouple wired clamps.

It just has compatibility with the Jobling probes. Okay, so you have to buy the job link probe separate okay, so I just want to make sure I was thinking about that. While I was on vacation because a lot of people send me emails thinking how cool they are, and it's like man, I hope they don't get misled by me. Okay, but hands down field piece in my opinion, is one of the better manufacturers of tools out there.

There's a lot of good ones: okay, but they're, one of the better ones because they have a great product, but they also have great customer service. Okay, so and they stand behind their product. If something happens and and stuffs happened - okay, I you know if you drop it or something like that, you know I'm not saying they're gon na cover everybody's stuff, but fuel piece has always been really good to me even before I started beta testing for them. Okay, so - and I've heard nothing but great things from other people to about their their return policies and different things like that: okay, so yeah, but I dig the field view stuff.

So all right, let's see what else I'm going in here: Wow cool 115 people in here at least that's what Brian says. I really appreciate you guys if you guys hit the thumbs up button. That really does help my stream so smash that thumbs up button. It really makes a difference: okay, okay, so Ralph.

You said: why do you need a heater high-limit if the defrost termination shuts off the heaters? That's a good question. So the heater high-limit is a redundant safety, and what that means is that it's just a second safety device. Okay, you know on a at least on a commercial package unit. We're gon na have two high limit temperature switches on the heat section: okay, the gas heat section just in case something happens that second one's gon na protect you, okay on an evaporator Cole and I'm gon na give you an example when those strip heaters on an Electric defrost walk-in freezer evaporator coil when those strip heaters turn on they're putting off quite a bit of heat load.

You got to figure out. You know you got to think that they're gon na melt or they're there to melt essentially a total, totally iced up evaporator within ya 30 minutes give or take okay is what it's typically there for. So it's just a redundant safety. Having that second high limit switch and I'll give you an example, I had a restaurant that I wish I still had pictures because it was a good ten years ago, but I had a restaurant that had they were shut down and a new guy bought the building And it was an existing restaurant before, and power was left on to a couple things, and one of the things that was left on to was the evaporator for the walk-in freezer.

But the unit had a bad compressor. Okay, so it just sat there energized for days and days and days, probably weeks, to be honest with you and when we went to go survey. The restaurant for the new owner, the fan guards for the evaporator were literally a giant glob of plastic running from one screw hole down to the ground. It completely melted the fan guards and then it started melting.

Some of the plastic racks that he had inside of the walk-in because it was sitting in an insulated space. The door was shut, the light was on in the walk-in freezer and then the heaters were turning on and off essentially four times a day for thirty minutes, and this went on for so long until it actually brought the temperature up to the point that it was Melting, the plastic inside of the walk-in okay, so those heaters they do have the potential of getting pretty hot, so those safety devices are there just as a like ice, just a redundant safety. Okay. So that's why you're gon na have a high temperature limit on top of a defrost termination, so on a walk-in freezer.

If you are in defrost and the temp gets above, like 55 degrees or 65 degrees somewhere in, there is usually where the defrost termination switches at it's going to send power up to the ex terminal. And if the ex terminal is hooked up and that's the key thing, if, because most of the time the ex terminal is disconnected, but if the X terminal is hooked up, it's going to pump the defrock the unit out of defrost and it's going to start the Refrigeration system back up, but if someone has the ex terminal disconnected it might not pop the unit out of defrost, depending on or even if the heater limit has been completely bypassed, which I've seen that before too or I'm sorry, the defrost termination has been completely bypassed. You can get some high temps, so it's more again just to make a short answer, long, whatever it's just a redundant safety. So, okay, let's see what else I am missing inside of here.

Okay, guys again throw some more questions down in the bottom. I really appreciate you guys coming in here, throw them down into the bottom and I'll try to get to them. Okay, chase and Jason. You said you sent your resume I'll have to look that.

I can't remember if we had a conversation about that or not but I'll I'll, see what you got in my email and stuff. Okay, coming back to the live streaming, videos thanks dark storm! I really appreciate it man right on how difficult was it to set up the digital evap control from ke to therm, and did I like it Jason yeah? I really dig the the key to therm products and so the first time I made a video on a key to therm product. I was very frustrated very frustrated, okay, because it was a Friday night service call out to a restaurant, and when I went out there it had a giant controller, and this was their evapo fishin si controller. Okay, it'll be the first video that I had a key to therm.

I think it was a walk-in freezer with two mini defrost was the title of the video. So just like, I said in the video - and I think I showed my frustration to that night in the video, because I walked up there and I was like what the heck is. This thing it was like a giant computer running the walk-in and I just needed to get it fixed and I didn't have a manual and I was frustrated. I got the unit running, it was low on charge and I pretty much ignored what the controller was saying.

Luckily, the controller was still working and I came back the next day and when I came back the next day, I ended up getting a hold of Keita therm and talked to technical support and my mind was changed. I hooked up my computer to it and this is their big controller. Okay, this is the fanciest one. They have.

I hooked up my computer to it and I realized how awesome that control was so the next day. Basically, my mind was changed. Okay, that first night, I I probably said son, I think I said some crappy things about him on the video. I think I was honest you know like this is junk and all this different stuff, okay, but once I got it set up, it was awesome.

Okay, and once I got my computer hooked up to it, it was like wow, you know, being able to see the graphs and different things on the Keita therm evap efficiency controller. I can really see the the savings that we could potentially have with that kind of equipment and imagine if the customer would let me hook that up to the network and be able to access that from the office. They could call me and say: hey my walk-in freezers, not working, and I could log in and look at the trending data, okay and on that particular system. I think I showed on that.

Video like I could tell, because that that unit did have a refrigerant leak and I could see the refrigerant leak in the trending data. You could see the temperatures slowly just going higher and higher and higher, and it was it wasn't like a giant spike like the compressor went bad. It was just a gradual change over a week. You know, and you could see it in the graphs and it's like man.

Well, you know that the ability with these digital systems and digital controls, that we have once we understand them and know how to work with them and get past the pack that they're different okay, that they're gon na save us a lot of time. Once we get dialed in on them now I have worked with a lot of their smaller controllers. Honestly, I haven't been able to sell one of those big evap efficiency controllers to one of my customers, because they're, a big expense and it's a-you know to put any vapp efficiency controller. If you do it all right, you're gon na put an electronic expansion valve.

You need sensors, you know you're gon na have to rewire some stuff. It's nothing that I I don't think would take me but four hours to install a system. Maybe I'm talking retro control system for one of their walk-in freezers or something like that. I don't think it'd take me about three to four hours to install it, but it's a big expense for the customer, so I haven't been able to sell one of those to one but I'd love to okay.

What I have been selling is their their tenth plus defrost controllers, those things I've been using like hotcakes lately, okay, so essentially it's a temperature controller with defrost built into it. I will say on the tenth plus defrost and I'm gon na be honest with everybody. Okay, there is a flaw in it: okay, and the flaw is the fact that you can't do a different timed defrost for different cycles. Okay, and what I mean by that is, is that in the controller you select how many defrost you want a day right, and then you select how much time you want the duration of each of all the defrost to be okay, you can't say: hey, I want Defrost one to be twenty minutes and hey.

I want defrost two to be ten minutes, and so that's the only flaw that I see in the key to therm, 10 plus defrost controllers, but nothing's, perfect. Okay. What I try to do in that situation with restaurants is I like to, in the middle of the night, on a problematic system I like to do an extended defrost so like, for instance, I haven't made a video of it yet, but I was out on a Service call this last weekend on a walk-in cooler that has a bad door and the customer needs to replace it, but they're not going to replace it for about four weeks. Well, the door literally keeps getting left open and it ices up thieve a protocol.

So I was thinking about putting a key to therm 10 plus defrost controller on there, but I wanted to do an extra-long defrost in the middle of the night. So instead I haven't done it yet. But I'm gon na go back and put a grassland defrost clock on there, because I can change the duration of defrost to do a really long one in the middle of the night and then just normal defrost during the day. Okay.

So but I really dig the kita therm products, you know and I have no affiliation with them other than me talking to them through emails and different things. Okay, so you know I even if I did have an affiliation with anybody, I'm gon na be, you know, like I'm gon na, be completely honest about everything, guys, okay, so if I, if I start working with someone, you know I'm gon na be upfront with that And let him know like you know, I'm gon na say it like. It is that's how my channel works. Okay, so I'm gon na tell you guys what I honestly feel about things.

So I'm not gon na lie to you guys and try to push something down. Your throat that you guys don't want to hear something like that: okay, all right! So I'm going to go back to my sheet right here, real quick and adjust or finish what I'm doing. Okay. So I had another question about, and this is kind of a vague question a little hard to answer, but it says how the person asked me: they have a small refrigeration company and they really want to get into like the chain.

Restaurant work. Okay, because I do a lot of chain restaurant work and a couple things with that in the email. I can't remember if that was I'm gon na blend together a couple emails and just cover a couple things in this. I also got another email where someone said hey: how do you stay so busy? First off, you got to understand, I'm not as busy as I look in my videos.

Okay, there's times that I slow down we're a struggling business just like anybody else. Okay, but you know I tend to. I have a lot of what do you want to say I mean I go out and I put up two videos a week: okay, but that's not seven days worth of work, making two videos; okay, so we're not as busy as you may think that I am. I mean we're just like any other contractor.

It's early spring, we're still kind of slow. So now, with the chain restaurant work, someone asked how to get into chain restaurant work. That's a really hard thing to do. We have been involved in chain restaurant work since before I was part of the picture.

Okay, remember I work with my dad and we've since partnered and we own the business together now, but he started it in the late 80s and you know just by luck, got involved with one of the big chain, restaurants and it's kind of going from there. It's been that one chain restaurant that has led us to what we've done or what we do today, because you, when you're honest and you treat people right when a manager leaves there and goes to another chain. They remember you and that kind of stuff. Okay.

So to answer the guys question: how do you get involved in chain restaurant work, the the easiest way that I could say to do it right now is not the most favorable way, but it's get on with the the refrigeration manufacturers and become an authorized warranty provider. If you become an authorized warranty provider that gets you in the door do warranty work, warranty, weren't doesn't pay very well, but it gets you in the door and you can hand out your business card now. That is not a fail proof way to get in. I mean with some of these big big chains, it's almost impossible because it's getting to the point that they want you to take on.

You know all of Southern California. I've got some of them, they're like we want you to take all of Southern California, and I can't so then they don't use me and they use someone that will okay, but then they get dissatisfied because you know you run into problems with companies that big butt. So it's a difficult thing getting into chain restaurant work. The easiest way, like I said, would be, in my opinion, to start doing, warranty, work and just go from there.

I mean it's, it's really kind of a luck thing to once you get going with it. You got to be honest and you got to be fair and you got to take care of the customers. Sometimes you got to take a hit, you know and chain. Restaurant work don't get me wrong, it's not as as pretty as it looks.

I mean we deal with all kinds of drama. You know one of the things about chain. Restaurant workers is they demand that you do their warranty work and they demand that you don't charge them any extra. Well, warranty work doesn't pay.

Your normal rates doesn't pay all the hours that you have involved. It's just one of those things you got to deal with. Okay, so you got to learn how to play the game and go with it. Okay, but all right, I'm going to see if I'm missing anything here in the chat, how many hours - okay, so that's a good one Clayton.

How many hours do I work, how much family time? Okay, so that is a struggle that is the real struggle when dealing with Restaurant, refrigeration or refrigeration in general is how do you have time for your family? I got an interesting thing coming up where I'm gon na address some of those issues coming up, I'm not going to reveal how we're gon na do that. But that's that's. I think that's gon na be a really interesting topic, so that one is coming, but I'm gon na kind of go into it a little bit right now. So, to be honest with you, I have an understanding, wife and I have understanding children.

Do I spend enough time with them? No, absolutely not do I wish that I could spend more time with them heck. Yes, okay, I've gotten to the point that right now and this isn't great business practice, but this is what it is. Is we turn down work because we don't want to get any bigger? Okay, you know I it's part like. I said it's not good business, because you know I I'm turning down work to new restaurant chains and different things.

Okay, because I don't want to sell myself short, I don't want to overextend myself. I used to do that. We used to go all over Southern California, I used to go to LA and it was nuts okay. Recently I had to go into Los Angeles, which is the scary thing is, is Los.

Angeles is only about 50 miles away from me, 4550 miles away and the other day I had to go for a training class, and I sat in two and a half hours of traffic to get there and two and a half hours of traffic to get home. I don't like that anymore. I don't like doing that anymore. So it's not worth the struggle to me.

I let go of a bunch of restaurant customers recently, oh, I should save five years ago because they were in the LA area and they were good, paying customers and some of my busiest customers. They were great money and they paid me for travel time too. We got we got paid to drive to the customers job site. We always made an agreement with a customer that we wouldn't charge him any more than an hour travel time there, sometimes an hour and a half just depending so we never got all of our travel time but still, but we gave that up because the the the Experience on all of our guys and the stress on all of our guys was just too much okay, so again, probably not the greatest business thing, but it made our employees happy.

So we had to cut back on some of that stuff. So right now we're a little bit slow. Realistically, I'm working about 35 hours a week. Most of my guys are probably getting 40 hours a week right in their 35 to 40 hours a week, and I spend you know quite a bit of time at home.

Right now, but you know the spring time is coming: it's gon na get hot we're gon na hit temps about 110 115 out here in SoCal this summer and we're gon na be busy, and I'm gon na essentially be working, probably 60 hours, sixty-five hour work weeks. So it's not too crazy. You know we try to keep enough guys, but I'll yeah I'll be doing 65 hours during the summer, so yeah it gets harder and harder to spend time at home. So you know it's just one of those things.

I don't have the answer for that one. It's a difficult struggle. I just you know, do my best okey-dokey see ya. California.

Traffic is terrible. Okay, any more questions, guys, throw him down in the bottom of the chat, put him into caps lock. So that way I can get to them. I'm gon na go on to some of my other stuff.

Okay, I got to say a very, very special. Thank you, I'm not gon na, say his last name, but his first name is Cyrus, he's a an Air Force or he's in the Air Force and he's deployed overseas right now. Thank you for your service Cyrus. I really appreciate that I was he reached out to me because he wanted my opinion.

I'm not gon na tell you that I saved the day or anything like that. I didn't cyrus already had his problem. Figured out he's a service technician in the Air Force, he's on an Air Force Base overseas, and he reached out to me because he just wanted a second opinion on something that he already diagnosed. Okay again, I really didn't do anything other than listen to what he had to say and kind of basically confirm his diagnosis, which is that the system more than likely, has a bad compressor.

And I got to say I was so stoked okay to be able to help him, or at least just talk to him. That was the coolest thing in the world to be able to talk to someone wherever he was at okay. But then, on top of that, like two weeks later, I don't even ask me how I got a package in the mail and it was full of a bunch of like great coffees and chocolates and different things, Cyrus dude, that was totally unused in just super thinking. I'm not asked, I don't want anybody to send me anything or anything like that.

Okay, because I didn't give the guy my address or anything like that, okay, but I was so blown away that the dude sent me a package like goddess say. Thank you. So very much Cyrus really appreciate it again. Thank you very much for your service dude, all right, okay, seeing what I'm missing in the chat making sure I'm not missing anything! Remember: okay! I'm going to install it tomorrow, any tips or watch out for okay, so wired zero one one you said: spoilin has a TX v kit to make a non-adjustable TX v adjustable ka4, I'm going to install one tomorrow, any tips or to watch out for it's on A five-ton Aon unit for a computer room, that's very interesting.

I didn't even know that they had a kit to make a non-adjustable TX v adjustable, I mean imagine if the valves rebuildable, I can see how it's feasible to do that, but any advice just take your time. I've never done one. So I honestly don't know what you're expecting I'm assuming you're just gon na take the bottom of the valve apart and screw in the new part. Just make sure you pull a great vacuum.

You know I wish I had more to tell you but yeah. I really don't know I'd be interested if you want to send me pictures of it. I'd like to see this kit wired, zero-one-one, I'd like to see what it is just like shoot me, a quick pic of the before and after, and show me like. Well, you know some pics of what you're doing I'd be interested to see that but yeah I've never done.

I've never changed one from non adjustable to adjustable ya. Sacrament. Do you yeah? I will do that. That is a good one.

So Sacramento is asking me if I'll ever do a video on the actual spoilin 90-30 one charging method for charging a system with the receiver and a head pressure control valve. That is a really good idea, and I will do that. I will say well. I won't let me let me make an email before I announce that but yeah I will um.

I will work on that. That's it that'd be a good idea for video, and I could probably do that one where basically, I'm gon na measure out the condenser figure out the total equivalent link the return bends find out the total volume of the condenser figure out. How much of the condenser you need to flood and then do that calculation so I'll do that it's not a really really hard thing to do so. Yes, I will.

Okay, so Malad, you said: studying commercial refrigeration book by dick wars, working commercial HVAC, five plus years experience in HVAC never touch low, temp switch to low temp company or keep book-learning low temp. You know what bud you just need to make the switch, but you need to be honest with the company and let them know that you're still learning and hopefully they'll train you and you'll learn on the job. I mean honestly, if you understand the refrigeration cycle, and if you understand what saturation temperatures are you got it dude, you just got it there's a little bit of a different construct, control strategy, but you know our trade isn't about remembering like exactly how things work. It's about being able to get in there and diagnose things.

If you understand the refrigeration cycle, you can figure it out. It's not that hard. I mean. I don't want to make it sound like it's easiest thing in the world, but you got this: you could do it dude, so, okay, Clayton.

How long do you ride with another tech until you get your own work van after school dude? That one is totally up to you. It all depends on how much you retain from school and how much you show the service company. You can do. Okay in a perfect world like if money, wasn't an issue I'd like for someone to ride with me for two three years: okay, like a proper apprenticeship, but that's not realistic and that's not really gon na happen, but in a perfect world.

That's the bitchin way to do it, because then you learn slowly and you learn how to do things. Okay, but realistically I would say that you know, probably no more than a year, some I'm gon na be honest with you. Most companies won't even keep you in a van for three months with someone else, but I mean no more than a year. You should be able to pick up the basic stuff and be able to do basic, preventive maintenance, -- es and then slowly venture out on your own.

So but it all just depends on the person primetime. You hate Head, Master valves, yeah yeah. You know a lot of people, don't like head pressure, control valves. They don't bother me, but you know what I'm in a mild climate, I'm in Southern California.

So you know our winners, don't get very cold. So you know I. I hear a lot of people up in the north and different things in primetime you're up in Canada. Aren't you if I remember right so yeah I've heard a lot of people saying that they have a lot of problems with them, but I'm gon na be honest with you dude.

I I I think that the majority of the problems with like head pressure, control, valves and expansion valves and all that different stuff I'll honestly dude. It's got ta be user. I mean not user error, but installation error. It's got to be poor refrigeration practices, man.

It's got ta, be you know it, I just I don't know, but maybe you guys see something that I don't, because I don't have a lot of problems with head pressure, control valves, majority of the time. The problem with the head pressure control valve is: is that the systems under charge or it has a refrigerant leak, that's the problems I run into, or some dodo-head went, bypassed it and didn't tell anybody so, okay, seeing what else I'm missing in here I got ta Say, thank you, but I I know nightbot Singh here, but I do have to address the guys. Thank you so very much for the Porter's on patreon really appreciate that.
