Ah, it's time to chill out and get ready for a mediocre. Qa live stream if you're old enough grab yourself your favorite adult beverage and if you're not stick with apple juice, put your feet up and relax. If you have any questions feel free to ask them in the chat and now, let's queue up the intro music. What's up, ladies and gentlemen, guys and gals out there this week, I'm gon na be changing my name to the curious computer hacker guy.

Now, a lot of you guys probably would have guessed this, but Chris isn't very good with this pass for it. So I just happened to be able to hack into his computer tonight and if you guys want to know his password is actually unicorn princess. So that's why I'm here I decided to take over for a while. So tonight I am going to be your HVAC, our videos, guy, as you can tell I am Chris Stephens right there, no right there yeah right there, so Chris Stevens! That is how you spell his name too, with a definite ns, so tonight we're not gon na.

Do any of this boring stuff that Chris always talks about there's a refrigerators and TX fees and whatnot. Instead, we're gon na do something much much more fun. We're gon na talk about Michigan mechanical codes, I'm sure all of you guys are really interested in boiler top clearances. I mean who's, not interested in that boiler connections valves.

I know Joe Canada Adam even probably Justin Beaver all there. You guys probably go nuts with this right now: hot hot water boiler, expansion, tanks. Now, if you guys do get bored of me reading you the International Mechanical Code or Michigan's mechanical code, after that's done, I got my Rubik's Cube, so you guys can watch me. Try to figure out this rubik's cube, let's get that started first, because nobody really tunes into these to really learn about anything they just tune in here.

Just to talk in the chair. Let's be honest right. Nobody wants to tune in to listen to chris babble, on about refrigerators and all that magic nonsense. I mean what is it GX for you? Really, nobody needed needs, TX fees, I mean really.

If you, if you ever, are in a situation, you have to replace the TX v, all you got to do is take say we'll, say a half-inch piece of copper and you crimp it down. Not all the way you crimp it down just so. It's just barely open boom right. There t -- xv problem solved, so you guys can take that one to the bank right there.

I learned that from spoiling captain spoiling himself so now you guys ever do find yourself trying to solve a Rubik's Cube. First thing I want to do is try to get these white ones in play right, so we go like this, then we go like this see and we got the white one it there right now we got to do our green one. Now, if you guys do decide to unfollow Chris, because this channel is boring now you guys can always head over to this guy right over here in this corner. Let's see if I can get right there curious HVAC guy, I don't know him, but he does a pretty good job.

I hear excess you can tell I'm Chris Stevens, so ya should probably just unsubscribe from Chris Stevens channel and then just go right over there and just totally follow that guy he's cool he's got awesome, voice and a beard, and it does basically the same thing. Just does a lot better. You know there's a lot in a much cooler way. So so how much do I got to pay you for this bill yeah? Well, I can have my screen back.

Hey, please, son! No, wait. Can I swear on this? What the hell? I thought I had you locked out I'll get in here and change you, but this is not brought to you by spoiling. Your password is now password instead of unicorn princess. What would you have to share that with everybody? For how do i, how do i? I don't like you out of this.

I'm gon na take this back over. I want my strand back, get the hell out of here all right, how you guys doing this evening. Hopefully you guys are doing well. Obviously, if you guys don't know who bill is bill is curious.

Hvac, guy cool dude definitely check out his channel highly suggested guys as usual. We just thought that would be kind of funny having Bill come in here, but he's cool dude. He has lots of great videos on his channel, so definitely guys if I try to post a link, maybe we'll get the link posted in towards the end, but obviously just look up curious, HVAC guy on YouTube; okay, definitely good stuff to catch a couple, different topics. We want to talk about tonight and then we will get to your guys's questions as usual and let's see if I can click this this silly thing.

Ah there we go right there. There we go. You guys don't need to know my name cuz. You know who I am so alright.

No, I do not have comedy on my channel so bills, the funny dude, I'm not funny at all, I'm all serious and all about business. So alright, so a couple different topics I want to cover tonight as usual and then, like I said, we'll get to you guys's questions. So one of the things that I I have constantly and I've explained this so many different times. Okay, that I just want to try to do it again: okay, so err balance.

I am NOT a certified air Balance. Technician, okay, but I know enough to get me in trouble and I constantly constantly get the question: what is air balance? Why do we need exhaust fans? You know why do we need make-up, air? What's the difference, so I know I've talked about this, probably a bunch of times, I'm just gon na go over it really quick. I have a really easy explanation here for air balance. Okay, right here, paper, bag.

Okay, what you do is you take some spray paint, you spray it in the bag. You put your mouth and I'm just kidding, but um, so paper bag just a silly paper bag here - and this is just going to you know, just give you an example of air balance and how it works. Okay. So if you take a paper bag - and you put it over your mouth and you stuff - the bag collapses right.

Okay, if you take that same paper, bag right here cut a perfect hole in the bottom of it alright and you suck through the bag. Nothing happens. The bag doesn't collapse. Okay, I know that's silly, it's simple, but it's the easiest way for me to visualize air balance for people.

Okay, if you are using exhaust fans to pull smoke out of a building all right, whether it be medical, whether it be a kitchen whatever, if you're using exhaust fans to pull smoke out or unwanted air, you got to put air back into the building. You have to balance that out. We do that with make up air okay, oftentimes. We have dedicated make up air units.

The dedicated make up air units, basically supply air into the building to make up for what the exhaust fans are pulling out. All right, if you have a building where the exhaust fans are pulling all the air out, okay, then the building becomes negative, meaning that the doors are hard to open different. You know and when you do get the doors open, you're gon na get a blast of unconditioned outside air coming in through the doors, because you got a make up for what the exhaust fan pulls out all right. So, therefore, we're gon na use a make-up air unit oftentimes we use, like I said, a dedicated make upper unit, but with most restaurants, these days, they're only gon na pull about 80 % of the needed make-up air through the make up air unit and then they're Gon na pull the other 20 %, typically through the rtu units or air conditioning units via outdoor air, dampers different things like that.

Okay, that way they can bring fresh air in to help satisfy co2 requirements. Okay, one of the ways that we measure for well one of the ways that we measure the amount of people in a building because we have to do air exchanges for every single person to bring in fresh air into the building, is by measuring co2. So there's all kinds of different crazy stuff with that and again probably need to get someone a little bit more qualified to talk about that. But that's the simplest way to explain why we have to have a make-up air unit and why we have exhaust fans.

Okay. Next, I want to, and I'll definitely get to you guys's questions in the chat to do me, a favor and put them in caps lock, and that way we can see everything in there all right on my list here I had posted on social media today about An ice machine that I was working on, I was working on a hoshizaki ice machine and one of the questions that I got with that post. I posted it on Instagram, and one of the questions that I had gotten was why I invert my recovery tank when I recover gas or when I, when I push gas into the recovery tank, okay, so a while back, I be on the the vacuum pump and Recovery machine manufacturer had posted a little link and it kind of made sense to me and what they said was that on a recovery tank okay, there is a you've got your valves right here and on the valve. This is your dip tube.

Okay - and this is what separates the liquid from the vapor port okay - is this dip tube? Well, this dip tube is very small if I can get it off here. Okay, it's a it's! Actually, you can't see that through the camera, but it's actually the diameter of this is actually smaller than quarter-inch, and so a peon had posted this link, saying that you should invert your recovery tank. If you want to and charge the you know, push the gas in from the recovery machine through the vapor port instead of trying to push the gas in through the dip tube, because the dip tube creates more of a restriction. So that's why people always see it in my videos in my post that when I'm recovering gas, I have I'm hooked up to the vapor port and I usually invert my tank okay, it's just because of a way that a peon had said that it makes it Go faster now I have no scientific evidence saying that it does go faster, so I one of these days I'll do like an experiment where I have to recovery machines.

I have to basically have two of the same recovery machines, two of the same tanks. You know same temperatures and all that good stuff and I'll see if there actually is a speed difference, but I feel like there is a difference in the way that you are in the speed of the recovery, basically by hooking up to the vapor port. Another thing that I want to point out too, and I am gon na actually yeah bill - welcome to that welcome to the chat bill. What I'm actually gon na do here is share a little clip here.

Well, actually, I don't even need to share clip. I could just tell you guys: no, no. I will cuz it'll kind of explain something here. So let me change this over hmm nope.

That's actually not gon na work. So no we're not gon na share the clip right now. Actually sorry technical difficulties here for a second, let me see if I can figure this out, let's see well yeah, we are going to share the clip right now so hold on just a second and I'll go ahead and transition that over and I'm gon na play. This, for you guys real, quick, just a quick tip here.

You can't trust the colors on recovery tanks cuz. If you look at this one red is liquid. If you look at this, one blue is liquid: red is vapor to recovery tanks, for whatever reason different manufacturers use different colors. So you can never trust that you got to read.

So don't just look at the colors and think you got liquid and vapor always pay attention to that. Well, I don't think that quite worked out the way that I wanted it to, because I know that the screen wasn't showing quite right but again sorry for the technical difficulties. But the whole point is: is that two identical recovery tanks sitting next to each other? The red and the blue are not always gon na, be the same, whether it be vapor or liquid, so very important to understand that that's another comment that I get all the time is people saying: hey, you're hooked up to the vapor, hey you're hooked up to This well, each tank is different, so you always got to read what it says on there. So in this situation the blue is vapor, the red is liquid, but on another tank it won't be so you know it is what it is.

Alright um, let's see if we got any questions in here, I don't know if I see any yet, let's see probably a dumb question, but how are you measuring the pressure difference between the inside and the outside? Okay, so I'm assuming you're talking about air balance right. Is it our our force? C3J euphoria, I don't know what your screen name is there, but but um what you usually use is II. You can use a manometer, but it has to be a highly sensitive manometer but will usually measure it in. I believe they measure air balance more or less in Pascal's.

Don't they again, I'm not a certified air balance person, but although the only tool I have on my van is a manometer so I'll measure in inches of water column and just kind of see, but in all honesty I'm usually not measuring my air balance because I'm Not doing any certified, I'm just kind of winging it and just testing to see if the building I, when I'm gon na adjust an air air Balance on a building, I'm just gon na make it ever so slightly positive is what I'm gon na do so, but Again, I'm not certified in air balance. That's not my job! I've just done. You know it a little bit here just to get me. You know out of a bad situation and then usually I'll.

Let people call a certified air balance company to come in and adjust accordingly after we're done is usually what I do so have I ever worked with ammonia equipment. Do I recommend learning at Dawson? No, I don't work with ammonia equipment every once in a while. There'll be a gentleman that pops in here his name is Ulysses Palacios. I believe it's how you say his last name and he works with ammonia, but I don't sure I recommend getting involved in anything you can within the industry.

Okay, so ammonia is its own little niche and definitely if that's something, you're interested in go for it. Okay, this whole entire industry needs help in all the different sectors we have. So why are liquid receivers so common? I don't understand what you're asking me there. Hvac kit clarify your question, but I don't really.

I need some context to what you're asking there all right. Let's see what else, what kind of questions are we fielding right now? What kind of questions do you want to ask bud Steve Zeller just go ahead, I mean it really depends on what you want to ask man. I mean HVAC refrigeration. If I can't answer it I'll tell you so I'm not really good at explaining where babies come from, but I kind of have a general concept.

You know, I think I can figure it out, but you know I mean just you know, ask away, but all right, let me see what else am i concerned of fraction ization when topping off systems with blends? Not really so our 404 a is an Erie zeotropic blend. If that's the correct way to say it. Maybe my buddy Ralph can answer that question a little bit better than me, um yeah, a 404 a you. Don't really need to worry about it.

Fractionating fractionating! I think is how you would say that it's not really a big deal, so it was a big hype when they first came out with, like 410 a and 404 and different things like that. But it's it's the glide on it. You really don't need to worry about it fraction, a fraction, a ting. So if you have a leak, it's safe to top off the charge, but there's some other refrigerants that can be problematic, but the most common ones that I deal with 404, 410 and 448.

A you really don't have to worry too much about topping off the charge. So alright, let's see what else Chris, what was the big announcement hvac our vlogger? It was just that bill was gon na be on the show dude. It was just joking around me, and Bill have just been talking about doing that for a while. So there you go see, Dallas fan is Ralph in here and he's always willing to answer any questions about refrigerants.

He works for Honeywell, refrigerant, I'll, post. His email in here right now guys anybody has questions, ask him he's the man all right. Let me see what my next question is here Ken exhaust fan suck out the air from your AC. Can they yeah that's a good question, pretty cure forever? Well, okay, I think I understand what you're asking me so, yes, typically, an exhaust fan is designed with a special hood that exhaust is pulling out of.

Typically, it's not just pulling out of the ceiling and the way that the hood is designed is that it has make-up air coming into it, so the cooking equipment usually goes under the hood canopy again. I'd wish. I had some visuals to show you, but it goes under the hood canopy and when the heat and the smoke rises, the make-up air kind of, creates an air curtain and try it doesn't it's not perfect, but it tries to create an air curtain that keeps the Smoke in the exhaust fan and the make-up air just kind of recirculates and also gets sucked up, but also replaces what's exhausted. So, yes, exhaust fans do because a building is an entire envelope, so an exhaust fan would pull out conditioned air, so you do have to be careful about that.

You have to make the building balanced correctly. Now, if you think about an air conditioning unit, an air conditioning unit essentially is just recirculating air. So at some point, unless you're putting air back in it's it's gon na I mean the building's gon na become so negative that it's not gon na pull out too much air anymore and the building's just gon na become just this giant negative abyss. But there's always air leaks.

I mean we're getting super techy right now again beyond my realm of discussion, but sure I mean an exhaust could theoretically pull out conditioned air that you've you know put into the building yeah yeah. It definitely could the whole point of having a properly designed hood with the newer hoods for sure. It's gon na create that little air curtain and it's gon na keep the smoke and the heat inside the the hood canopy and you know, try not to pull anything else out from the rest of the building. But you know, there's all kinds of different ways about air balance and that you need to understand again getting way technical above my head and that you know you can have a perfectly balanced building.

But then you could still be pushing smoke into the the dining room or pulling dining room air into the kitchen across the the pass out line, which is cooling, the food there's all kinds of of things that you have to worry about when you're talking about air Balance: it's not just whether the building is positive or negative, so again going off on a tangent as usual. So let's see what else we got do I ask permission to film my videos in on my clients buildings. You notice that I am very careful not to show or share too much so yeah. My customers typically do know that that I am in filming.

You know we try to be careful again still. I do. I want to protect my customers, so I don't. Let anything be seen you know, I don't want people to realize what restaurants I'm working at now.

I do realize that some of you guys that are in the some of you guys that are in the or watching the videos. If you guys work in restaurants, you probably know where I'm working but yeah, we try not to share that. So you know we try to keep it somewhat secret. Basically, so that way we protect them.

Let's see what else all right, Steve Zeller, you bought a sub Co M 500 mega and was wondering if I use one first and foremost and ultimately you love it for compressors, but trying to figure out what else you can do with it on one two. Okay, so Steve be very, very careful about using a megger on on compressors, okay, megaron compressor can be it's really easy to miss. Diagnose a compressor Copeland has a article, and I will try and share a link to that article. Thank you very much for that.

Super chat, Andrea. I appreciate that, but yeah Copeland has an article gosh. I need the tech bulletins right now. I'm gon na try to pull it up right now, we're basically they tell you that using a megaron, a compressor can be very dangerous and you need to be very cautious about it.

So thank you very much mister Zack there. It says that you became a member. I appreciate that, but alright, let's see what else we got here, oh I'll try to share that article hold on just one second here and let's see if I can pull up this Copeland article. Sorry about that and let's see all I'm gon na do is ask the Google for Copeland megger test and basically it's gon na come up with an article and I'm gon na share a link in the chat right now and basically it says that Copeland doesn't recommend Using a megger for testing for an initial test, they basically say that they want you to use a mega o meter to do basically like a trending test.

They want you to test it over and over and over again and notice trends and the degradation of the windings. And basically, if you have moisture in the system it can, it can read like it has that insulation when it's just moisture, so they say that like if you start to notice bad readings like like the windings are going bad. What they want you to do is go ahead and change the dryers. Try to clean the system up if it's possible, remove the refrigerant pull a good evacuation on the system, repair, whatever leaks, recharge it and then do another major test and notice that the insulation values seem to be getting better because moisture in the system can indicate it Can give you a false, negative, false positive, basically showing you that it? You know it's got bad windings, something like that.

So all right yeah! I appreciate you saying they're showing that in there Zak, I think I need to figure out a way to make the new member little icon, because the whole thing about the members is you get like a little special icon next to your name, Zak, and I need To figure out how to make that bigger, but yeah all right, so I'm gon na share this link in the chat right now. You guys do me a favor copy, this link and check it out after the stream. All of a sudden, the whole stream goes blank because everybody clicks the link and it takes them to a new page yeah. That's what I get for doing that do liquid receivers effect, condenser and evaporator capacity.

Do liquid receivers effect capacity? Hmm, I don't think liquid receivers effect capacity. No, I can't see that being a problem. That's an interesting one! I'm try to turn my mic volume up here, just in a little bit. Hopefully that makes it a little bit better.

Is that any better there? Hopefully, I'm not clipping now yeah that should be getting better. I'm seeing the volume come through better right there, all right, let's see what else we got going on anyone, okay cool! Is it common to perform a temp rise on an AR tu and adjust manifold gas pressure? According to this, I don't know what you're asking me there about Evan, so definitely uh. If you could rephrase that I would try to get to that and answer it. A little bit better for you all right, let's see what else! Okay, I'm gon na, go to my list of things to talk about here, real quick and try to go through it, so guys.

What I typically do on these streams is, as I get questions and emails, I try to address them in the stream, so I usually have a sheet right here in front of me real, quick, common things. I get all the time guys: okay, topping off the refrigerant charge in the United States is perfectly legal so long as your system contains 50 pounds or less of refrigerant, okay, you're allowed to top off the charge. Once you get over 50 pounds now, we have new laws coming into effect as of the new year, but as of right now it is perfectly legal for you to top off the refrigerant charge. That is, and I get quite often, how can you top off the charge to get them running? That's just how it works.

Now I realize in some of the European countries and some of the other countries around the world they're far ahead of us and it is completely illegal to top off the charge you have to fix, leaks and go on, but here in the United States it is Perfectly legal: if your system contains 50 pounds or less of refrigerant to top off the charge and then go back in later and try to fix leaks and in fact I don't even think we technically have to fix the leaks. But obviously you want to fix the leak so that way they don't have to keep buying refrigerant, but yeah. That's one of the things I get all the time is people asking me about topping off the charge. Do I work on water cooled condensers Isaac? I have in the past, I don't I don't, have any water cooled stuff right now, but I have worked on water-cooled systems.

I've worked on systems where they just pump and dump they pump the water in and they just dump it right down the drain. Those are pretty much for the most part outlawed here in California, but we still do have a few people that have the old-school pump and dump systems. We also have closed-loop systems where we are. You know basically pumping recirculated, glycol and different things like that.

We have open-loop systems, there's all kinds, but yes we do have them. I don't work on them very much. So, let's see what else can I go over hoshizaki ice machine schematic Eric? I'm not gon na go over the schematic on this, but we can definitely talk a little bit more Eric. What I'd highly suggest you do is sending me an email to HVAC our videos at gmail.com and, and let me know what it is exactly that you're you're wondering about as far as the Hoshizaki schematic your question, actually segues, meaning into another thing.

I wanted to talk about is constantly. I get people asking me questions and you know why they're asking me how come I don't show the entire process in my videos how come I don't show from step one to step ten. You know how I went through this and and did everything. Okay guys, you have to understand something.

My videos are meant for service technicians. I do not want my videos to replace or to take a service technicians job. I do not want DIY people watching my video and trying to fix their own equipment. Now it's inevitable that some people are gon na watch my videos and be mechanically inclined enough.

Try to figure things out. I can't control that, but I try to do my best to leave certain components and certain parts of my videos out purposely because number one all of two reasons, liability and I don't want to replace or take away from anybody's. You know work okay, so, for instance, people ask me hey: will you show me how to set your your pressures on your your oxygen and acetylene rig when you go to braise something up? No, I won't because that's a massive liability. If I show you guys how to set the pressures, because what happens, if something happens, okay, I can't show certain things like that.

But yes, if you have a specific question about a hoshizaki schematic, send me an email and maybe it's something I can address as far as going over schematics on the live stream. It's just gon na be two. You know user specific and it's gon na bore everybody else out, so I definitely see a lot of hey guys. I see that new people becoming members.

Thank you very much Adam and then, let's see who else I see a bunch of people popped in there right now, I'll have to get to them and thank you guys, they're going by so fast on my screen. I can't even tell so thank you guys very much all right, let's see what else, how do I cool a compressor that is getting hotter? There is plenty of oil ice machine rookie. You asked me: how do you cool a compressor that is getting hotter? Well, it really depends, I mean compressors do run hot. You need to find out whether it's too hot, that's the question, but compressors aren't cooled by oil.

Okay, the oil is running through the system. Lubricating the components inside the compressor okay to keep them from building up. Friction and getting too hot okay, but the actual compressor is cooled by refrigerant, suction gas. Coming back to the compressor, so the suction gas coming back to the compressor is actually what cools the windings okay.

So now, if the compressor was low on oil, sure the components inside would get excessively hot and it would create extra heat. But there's already heated compression happening inside that compressor based off of the Pistons compressing the refrigerant okay, and that is simply cooled by the suction gas coming back. So if you have overheat issues, it could either be due to lack of oil. It could be a faulty compressor or it could be that your super heat is too high, coming back to the compressor and it's causing the system to overheat, but some compressors also run hot in general, so it really depends.

Let's see what else. What's my experience with Alto Shaam, quick, chillers, honestly storm, I have no idea. I've never worked on those but wish I did so. Let's see what else here, how do you know compressor running too hot besides it's shutting down on thermal a good question Justin? That is a good question, so hoshizaki they're a good point.

I should say Justin um, I'm sorry now, Hoshizaki Copeland basically has a check and they tell you that. Essentially, I think the hottest you want to see a Copeland compressor. Is it 225 degrees? I think you want to take, I think it's 225, if I off the top of my head, the Copeland mobile app would certainly probably tell you that, might it might not, or you can find a Copeland tech bulletin, but basically you're gon na take a discharge line. Temperature about six inches away from the compressor, and I believe they don't want it to be anything over 225.

If I remember right for Copeland scroll compressors, because after that point the internals of the, I think it's like six inches away from the discharge or the head of the compressor. If it's 225, then that means the internals are much hotter and it's it's starting to break down the oil. So alright, let's see what else we got yeah there you go Zach over 225 is pretty bad. Alright, let's see what else we got in here guys.

If I miss your questions, definitely post them in there again, okay, guys and I appreciate all the people that are becoming new members. Thank you very much. Let's see what else yeah 227, but the interesting thing John John McMaster, is that the 225 or 227 is actually on the outside. The internals of the compressor are much hotter, but that's the measurable, measurable temperature on the outside that they know that if it's 225 six inches away from the you know the outlet of the discharge, then the internals are like whatever temperature.

We should try to get someone from from cope on one of these times to talk on here, so JYP HC for those of you guys if you want to join as a member, so JY c HC HC. If you look at the youtube page, there's the ability to join as a member, and essentially it's like it's supporting the channel just for, like i think, there's different tears like dollar ninety-nine $ 2.99 different tears like that, and that's how you join it just supports the Channel, it's just a monthly reoccurring charge if you guys can choose to cancel it too. So at any time, all right, let's see what else we got going on. What's my experience with epoxy dipped evaporators, okay Ralph, you can help with what what did I miss on that? But anybody can you clarify what you're saying you can help with Ralph storm? You asked what's my experience with epoxy dipped evaporators.

I have no problem with the epoxy dipped evaporators. I have lots of refrigeration evaporators that have epoxy on them. I kind of question whether or not sometimes they make it too thick and I worry about the BTU or the heat transfer being negatively affected, but everybody that's done. Epoxy dip.

You know dipping on their evaporators. They seem to say that it works fine. I don't know that it completely eliminates the whole point of dipping and evaporator and epoxy is that it reduces corrosion for reaching coolers and different things like that. The contaminated air from the the vinegars and the salts and different things like that citric acids and different things in the air attack the copper and deteriorate it that's.

Why? Sometimes, if you open up like a reach-in cooler, evaporator I'll, be turning all green and blue in different colors, that's because of corrosive stuff in the air attacking it. So that's where an epoxy dipped, evaporator or we might call them a coated evaporator - would help. Now, where I will say, I have a problem with coated there, you go Ralph you're gon na, be my copeland engineer, for the show where i will say we do have a problem with coated is when they coat condenser coils, especially if the fins per inch are Really high, so that the fin spacing is very small when they have coating on them after about 4 or 5 years or what or after you do some really heavy-duty cleanings with, like you know, condenser coil cleaners, it'll start to peel the coating off the condenser coil And it'll actually block the condenser and it's hard to get that coating to come out, because this thin spacing is so small. So I have some situations where you try to blow the the loose coating out with like co2 or nitrogen or whatever, and it just doesn't come out and it causes high head pressure.

So that's some of the coatings. I really am NOT a fan of, especially when they use the epoxy coatings on condensers. I've seen it done it's kind of silly now they have some better ones that aren't really an epoxy and they work better on condensers. But you see that, like near the coast, a lot so POA can go hotter, but it's still not good yeah.

Definitely John. What's my experience? Okay, already answered that one okay. Is that measured 60 yeah? That is, I believe, that is Bill is the 227 or 225 six to eight inches away. Even your boss.

Has you checked temporized during your PM's? Okay, how many HVAC our branches careers? Are there? I've heard the HVAC. Our industry is used dusty, there's too many to list. I mean you have residential you. Have it just really there's so many different areas of HVAC you can go into.

You can go into building performance, which is a whole new, emerging sector in our industry. Right now, where people are going out and selling indoor air quality products, they're fixing air leaks, you know that can go into the construction side and the home remodeling side too. You can do building performance, it's kind of a harder sell in restaurants, but they do do building performance in big giant. You know office buildings and different things like that.

There's so many different sectors of this industry. So then you've got the refrigeration side. You've got the air-conditioning side, but then within the air conditioning refrigeration side you have scientific refrigeration, I mean industrial refrigeration, industrial air conditioning you could just keep going. We could talk about this for hours, there's so many different ways.

You can go within this industry. So, let's see what else, let's see you have to dumb curious questions? Hey, maybe curious. Hvac guy can answer you're curious questions. Alright, let's see what is the best evaporator and how do you make the evaporator much cooler ice machine rookie? Well, that's the there's.

What is that that that's really kind of a hard question? There's really? No. I can't really answer that one. I would suggest you send me an email, and we can talk about that some more and I can get some context about your question because that's kind of a really vague question, but it also doesn't make sense, but so yeah just send me an email. It's not a stupid question.

Just send me an email to HVAC our videos to gmail.com and I'll try to answer it for you. So all right, let's see have I slowed down Ernesto's asking me yeah, we're definitely slower right now. This week is always slow for us, and but this is my favorite time of the year, because I get to be home with my family a little bit more. I get to spend some time with my kids, you know, but the holidays.

Right now you know yeah. It's it's definitely slower. Definitely, let's see you're an HVAC building, engineer right on bud all right. How do I recommend cleaning, greasy condensers on self-contained units and restaurants as storm? So usually what I do is, if I can I'll go, get a super shallow pan.

Sometimes they have pans that are, you know four four inches tall and I'll slide it underneath the region or I'll pull the condenser out if it'll slide out and kind of tilt it. Let the weight of the compressor kind of lean, the condenser off the the reach-in and put a pan underneath it and then clean it. Sometimes you can't do that and you just got to let the kitchen management or the the chef or whatever know that hey I'm gon na make a mess and just go to town clean them with hot water. I prefer to clean condensers with hot water as much as possible unless it's just light lint that you can brush off and then, if hot water doesn't take care of it, then I'll put a chemical on it like the Viper HD cleaner or you can even go With like the the heavy-duty decreasing cleaners to new Calgon um refrigeration technologies makes one I think they call it coil bright or something like that so but yeah it's sometimes you got to get the restaurants dirty I try not to, but sometimes you got to do it.

So see what else we got, let me see yeah bill. You should definitely take Ralph up on that offer to do training. That would be awesome. What kind of pressures do I get on treated condenser, coils, r22 and for 10a? That's a good question.

I, wouldn't I don't know David air conditioning solutions. I mean really. The pressures are going to be dependent on outdoor ambient temperature in the coil TD, so but treated condensers, I'm assuming that you mean like with coating on them. You know, I don't know those numbers off the top of my head, but I mean theoretically, if the, if the man has a coil dipped, it shouldn't affect the TD.

So you know they should be using coil coatings that are very, very not very invasive. Basically and they're not going to affect the coil TD, so that that's the hopes, if you have one, that's really affecting your coil TD and it's causing higher than normal, condensing temps and that's a problem. So I don't you can send me an email, that's kind of a hard one to answer on here too. So, alright, are they using co2 in California yeah co2, we're not using it in the restaurant side, but it's huge in the supermarket side right now.

It's really emerging and the companies that have jumped on the bandwagon to get trained and work with the co2 are definitely ahead of the rest, because it's becoming a very popular refrigerant, ironically, with the co2. It's a transcritical systems, I believe, is what they call them, because they go super super high pressure, but you still again, I'm not super smart with those, but I believe you still have to use a secondary gas to cool it down right, which is you know interesting, But yeah I have no business even talking about co2. So how do I feel about ticket time paid for call versus hourly pay feed dizzle? So I am a time and materials company. We don't do any ticket time or you know we're paid by the hour.

All my employees are paid by the hour. Basically, so whatever they work is what they get paid and whatever we work is what we build a customer, so we don't do any flat rate or anything like that. I don't want to knock anybody for doing time, and I mean flat rate and different stuff like that. It's just it wouldn't fly in the commercial side here in Southern California.

I definitely see some benefits to doing flat rate on the residential side in my head again, I'm not knocking anybody for doing it, but in my head flat rate, doesn't really make sense to me: well, no, no, not flat rate, but the the whole likes paid for The ticket, or whatever you were asking like that, doesn't make sense to me paid per call and you know for employees. I think you should get paid by the hour, but I'm sure that it benefits the employees sometimes. So you know, I don't want to knock that. It's just not something that I deal with regularly, so I'd have to talk to someone and have a genuine conversation on how it works out.

But here we pay our guys hourly, just just like that. They get overtime after 8:00. And here and I know it's different than other states, but in California, if you work over eight hours, you get overtime. So I know in some places, if you work over 40, you get overtime so over eight in California, you get overtime over twelve.

You get double time and that's how it works here, all right. How can I make a condenser hotter ice machine rookie? I don't know, but I that's that's kind of a hard question to answer. How can you make a condenser hotter? You could reduce the heat, reject. No yeah, you reduce the airflow from the condenser fan mode or I guess, or you can make a condenser dirty.

So it's gon na get hotter I'd. That's kind of an interesting question bud. So I think that uh send me an email because you've got some other things to ask me too. So definitely ask me in the email and we can try to talk about it, a little bit more so um, let's see what else we got here, yeah block it off! That's how you can make a condenser hotter all right, Dallas fan, okay, so hey there, Chad how you doing bud alright, let's see, does anyone have any suggestions for learning controls online, Eric Goldhammer yeah? I do actually go to a website called HVAC.

Well, first off depends if you're in California go to a website, called it's about Q, comm and if you're not in California, go to HVAC our edu and they have a controls course that oftentimes is subsidized in California. I believe it's subsidized by the utility pay utility companies and you can learn controls online. You get a book and all that good stuff, but yeah definitely check out that website. It's the same company, but it's about Q is the California website or HVAC.

Our edu is the everywhere else and I believe you can do HVAC our edu in California too, but they have a lot online learning and a lot of times it's subsidized by the utilities in your area, so um, let's see have I ever done - work on VF V, RF systems. No, I have not David am i a fan of memes memes are funny on Facebook and different things. Okay, Oh another question. I get all the time.

I'm gon na go to my sheet right here. Guys real quick, constantly get this. One is why I'm so crazy because I wear my wedding ring at work and I'm being dangerous and I'm gon na get electrocuted, and you know I get so many different comments about that guys. I don't know how many times I can say this, but my ring is silicone.

Okay, it's a silicone, quello ring q.q alo! You can order them online, there's tons of people that make silicone rings. I, the cool thing about the silicone rings, are 25 bucks or something like that. You know for a nice one and you get all kinds of different colors, but I don't wear a metal ring. I wear a silicone ring so that way I won't get a ripped off.

What do they call it the finger ablation or whatever, where they like rip off the finger scan or whatever that's what I don't want to happen. So that's why I wear a silicone ring. Okay, so I'm not wearing a metal conductive ring, I'm not gon na get electrocuted. So, let's see what else, which is better a heat pump or a gas furnace gas pack HVAC kid: it really depends on where you live, but and how much your fuel costs are.

So in Southern California, heat pumps are starting to get more and more popular as different municipalities start, making it harder and harder for people to bring natural gas in, and I know that's like a trend right now in some of the Yuppie cities, where they're trying to Push out natural gas and there's there's a few like super super liberal yuppie cities in California, where they're really really pushing natural gas out, but in other parts of the country where natural gas is not feasible. You know they use oil for heating and then in some parts like down in Florida, they have a lot of heat pumps where they don't have a lot of heat. So it really depends on your your climate and what your your fuel costs are. Will the will determine which one is better for you? You know: there's there's Goods and Bad's the heat pumps, there's Goods and Bad's too, you know, combustible gas furnaces, basically, okay, so it really depends on your climate, and you know what your fuel costs are that that's? What it comes down to so um, let's see see you ask me a question on my walkin: doesn't work in cold video.

I don't. If I didn't answer your question that you had sent me like on a thing just send me an email. It's best to send me emails if I don't answer comments or anything like that, so HVAC our videos at gmail.com and I'll try to get to any of your questions or comments. So, let's see what else you wore what in Anzac I wore one for a long time too, and it was just within the last like three years I went to this silicon ring so yeah when social media got real popular and you saw those finger.

Those uh pictures and videos floating around on people's fingers coming off in different things. That's when it really got me thinking, but yeah. Alright, let's see what else um, alright, ok! So I'm going to I'm just looking at my list right here. I already talked about why.

I don't show the entire process in my videos, one of the things guys. I make mistakes. Just like you guys. Okay, I make mistakes all the time.

I have no problem whatsoever with people pointing out mistakes again, you're not gon na offend me. If you guys see something that I did wrong in my video, don't be a dick about it, but point it out. I got no problem with that. I'm open to all feedback.

Okay, and I know I make mistakes all the time guys. I am not perfect whatsoever. So if you guys think I'm some like you know, super tech, I'm not I'm just a normal dude that makes mistakes and I try to learn from them so but don't hesitate. I welcome feedback good or bad.

I welcome criticism, shout it out, throw it in there. Just don't be a dick about it. Cuz a lot of times like someone had criticized me about something I did and I had no problem with it. I left it on there and I was about to acknowledge in someone else in the comments attacked the guy.

You don't need to attack him, I mean whatever I usually handle comments. You know negative or positive. I usually address them so, but um yeah, I'm all totally open to it. Anybody has things you know, throw it in there.

Okay, someone had to ask me about Manitowoc ice machine fan cycle switches. Why do they fail so much Manitowoc ice machines on their CEO will actually on all their ice machines, whether it be a traditional remote or a cool vapor, defrost, remote? Okay, a quiet cube machine. They both have fan cycle controls and they both have head pressure control valve. So when you're dealing with ice machines, they need to operate properly at really low ambient temperatures and they need that discharge, gas or cool vapor to warm up the evaporator to help defrost the ice.

So we need that that warm gas from the condenser. Basically, so we have to use a head pressure control valve and we have to use a fan cycle switch now the fan cycles, which is why do they fail so much on the manitowoc machines? Well, it has something to do with the manufacturing and the quality of the switch, but you also have to understand that and on a Manitowoc ice machine, let's just say a cool vapor, a CVD machine, quiet, cube machine that machine makes ice every 14 minutes. So every 14 minutes it makes ice at the most, sometimes even sooner in a day. So if you figure you know, someone can do the math real, quick and a 24 hour day that machine is gon na harvest.

You know, however, many times if it's making ice everybody, let's just say every 15 minutes. Basically so every time it goes into a harvest that fan cycle switch, is gon na open and shut the condenser fan motor off, and then it's gon na close okay. If you have dirty condensers and different things like that, it's going to cause the system to run higher amperage and it's gon na cause the contacts inside that switch. But on top of that you know they.

Obviously, Manitowoc has a problem with the switches that they have been using and they've tried to fix it, and even the new ones fail a bunch too what I usually do on the Manitowoc ice machines and I'm addressing a question. That's why I'm bringing this up. But what I usually do on the man is walk. Ice machines is usually, if it's out of warranty, I put in a Johnson fan cycle control like a aftermarket one and it'll last forever, that has an actual capillary tube on it and it's not the little peanut style and then they last forever.

So anybody that works on ice machines - you guys are gon na know what I'm talking about with the fan cycle switches on the MANET walks. They fail all the time so and it's just manufacturing quality, so yeah. Definitely all all post Ralph's email right now. Let me see here we go and one of these days I don't know how I make it to where you can actually post things.

I need to figure that out Ralph where you can actually post your email in here. What's my take on vrf systems and do I work on them David? No, I don't work on VR systems, it's just not something that I've been able to get trained or start working on. I think they're cool. I do think it's a little bit ironic, because, a long time ago we went away from running refrigerant lines all over buildings, so like high-rise buildings and different things like that, we went away from it and we went to chilled water and we decided to confine the Refrigerant to the mechanical room like in the chiller or whatever right, and then it just cools water or glycol and pumps it all over the building.

But here we are we're going back to running refrigerant lines all over the building. I think it's great the efficiencies there and the the technologies there, but it's just funny because you know we used to have refrigerant lines running all over the building. We had leaks like crazy, then they went to chillers and pumping water and different stuffs and then now we're going back to running refrigerant lines all over buildings instead of using a chiller and cooling towers and different stuff like that. But but I definitely think vrf technology is great.

I have no problems with that. I'd love to learn more, it's just one of those things where it's been hard because we don't see it in the industry that I work in very much, which is restaurants. So, let's see what else do I consider equipment junked and how do I explain that to the customer storm, so I work for chain, restaurants, storm and the easiest way for me to the easiest way for me to explain things to chain. Restaurants is, let me explain this to you.

Sorry, I'm kind of saying explain a bunch of times, but most chain restaurants buy their own equipment, so I'm not selling them a new air conditioner for the most part. Okay, I'm not selling this chain restaurant whatever chain. It may be a new ice machine. They usually buy them direct from the manufacturer.

It sucks, but that's life. Okay, I'm usually just selling them the miscellaneous. You know needed installation materials and a disconnect switch in my labor. So it's really easy for me to go to a chain, restaurant and just say: look.

This unit is gon na, take $ 1500 little reach-in cooler $ 1,500 $ 2,000 to change the compressor, the evaporator and you know whatever. I think you should replace it. I'm not benefiting from that if they replace it, so that really helps me to tell a customer to buy new equipment. Now, when it comes to a customer where I'm gon na sell them equipment sure it becomes a little bit harder for me to push a sale on them because they want to repair it versus spending.

You know the they see the value right now. Let's just say: I'm gon na change, an air conditioner and whatever I'm gon na, throw a number out there that it's gon na cost fifteen thousand dollars to change, but it only needs five thousand dollars in repairs. The customer sees it as I can either fix it. For five grand or change it for fifteen, that's the way they see it.

So that is a hard sell and usually we try to educate the customers in that situation where, if I'm actually selling them a piece of equipment to say, look, I'm not gon na guarantee. My repairs, the equipment's old, you know it's got r22 refrigerant. You know the prices aren't too bad right now, but the costs are going up different things like that. So I'll usually approach them with the facts and I'm gon na be honest with you.

Most customers don't want to replace equipment, especially here in California, because it's so difficult for us to get permits to replace equipment the correct way. So it's a hard sell, but on the chain, restaurants, it's a really easy sell because they're buying the equipment themselves and I'm not benefiting other than an installation, usually I'll, make more money.
