Ah, it's time to chill out and get ready for a mediocre. Qa live stream if you're old enough grab yourself your favorite adult beverage and if you're not stick with apple juice, put your feet up and relax. If you have any questions, feel free to ask them in the chat and now, let's queue up the intro music yo, hopefully uh you guys are doing okay, you know with everything I don't know whatever. I guess it's all screwed up.

I shouldn't even ask if you guys are doing okay, we're all kind of just like getting by. Aren't we so yeah um, so hey! My name is Chris. This is the HVAC our videos livestream for the new people. I know there's a bunch of new ones coming in because I get these emails and stuff from everybody, so I kind of like to introduce things alright.

So I do these live streams Monday evening 5:00 p.m. Pacific. To answer the questions from all the YouTube comments, the you know, emails and different things like that. So you know that's the whole point of these.

I'm just trying to share the little bit of knowledge that I have. I get that knowledge from you guys from emails from reading articles and that kind of stuff, okay, so there's nothing special or magical about the information that I have in my head. I just read you know and just I'm just curious, I'm an inquisitive person. So one would say that I am a curious HVAC guy, but you know someone else already took that name.

So I can't really claim that one, but I've got a bunch of stuff as usual that I want to talk about, and I also want to address the chat. Okay, so do me a favor guys in the chat, if you guys have questions, throw the questions in caps-lock that way myself, the moderators can see them and I'll try to get to them. Okay, as usual, if I don't answer your question: keep reposting it. Okay! Until someone tells you to stop myself or one of the moderators, all right I'll, usually be upfront and honest and say: hey, I'm not gon na answer that and I'll ask you to send me an email or something.

Okay, I do have a movie quote and a song quote: it's gon na pop up in the chat. There is not a giveaway today. Okay, guys, I blew my wad on the last livestream. If you guys didn't watch - and this isn't something - that's gon na happen all the time, but if you didn't watch, I gave away four sets of field piece.

Jobling. No three sets of field piece, Jobling probes on the last live stream just randomly. I I only anticipated given away one, but then I don't know I just went kind of silly and started giving them away to everybody so congrats to the winners. You guys should be receiving him.

I know Ike had said he got his and the other people should have already received him if not in the next day or so. So you know I I like doing that. That was a lot of fun. I don't have anything else to give away at this.

Given time, but maybe in the future, we can do stuff like that again, okay, so those JobLink probes. I actually had him sitting at my shop and they were gon na be used for something different, but I figured what the heck we were in a weird time. Right now and I figured you guys - could have used a little bit of some kind of good feeling right and, like I had told Ike in an email. You know the whole point of me doing.

That was, I figured everybody's in a crappy mood and we're all going through a crap situation right now. So if I could just make someone happy for a few minutes or something because they want to set a Jobling probes figured you know that was awesome right. So I did it so yeah but anyways, so I don't have anything to give away tonight. Okay, it's! But I I encourage you guys to try to guess the the movie and the song quote, but you don't need to send me emails.

Just just do it in the chat, okay, but feel free, I mean whatever alright, let's see, I'm gon na answer this right, quick, Nelson JaVale or ho Bell. I don't know how you pronounce that you asked. Is the zoom lock tool worth buying it? Well, I mean the zoom lock tool. I honestly don't own the zoom lock tool, I don't have it, but I don't have anything bad to say about it right.

The zoom lock tool has a purpose and if, if you find that it would work for you, then heck yeah right, I mean you know. Spoilin is you know I am partnered with spoilin and they have great products. I mean there's a time and place for zoom. Lock, so I would highly encourage you to reach out to your local spoilin rep if you're curious about it, I'm sure that they will be glad to set up a time where they'll demo the zoom, lock tool for you that way, you're not just purchasing it upfront.

Okay, so if you don't have a spoilin rep to reach out to send me an email - and I will forward your information on to my contacts at sport hland and I'm sure they will set up a time to demo the zoom lock tool for you. If you're interested okay, so again, my email is HVAC. Our videos at gmail.com feel free. Okay.

I see lots of new people in the chat right now and let's see a Mike HVAC reefer guy, how you doing bud good to see you in here man all right, so I'm gon na go ahead and start getting to the list of things that I have To talk about guys and we'll go through it, so again you guys have questions, throw them in caps, lock I'll dive into him. Okay, so this last week for me, it still been slow. I'm gon na go ahead and address the elephant in the room. How is kovat affecting me the same as it was affecting me last week? Okay, I went from about six to nine service calls a day.

I have a small company with four trucks, including my own okay, so I have three technicians that work with us. So I went from about six to nine service calls a day to. I think I got four service calls. Last week, total all of my technicians are laid off at this time.

You know, there's not a whole lot. We can do. I deal with restaurants. That's 99 % of my work and you know they're just being very tight-lipped with the cash right now, which I don't blame them right.

Everything is kind of crazy, I'm here in Southern California, things are weird. You know we have one of the strictest lockdown situations right now and when I say lockdown it's not, you can go out of your house, you can do stuff, but they just don't want people eating in restaurants and stuff like that right. So I have talked to a lot of my restaurants and they are doing okay as far as to go and take out, but they're definitely not filling their dining rooms because they can't you know. So it's one of those things I wanted to address something too and kind of talked about this.

If you guys haven't or don't already know about it, I would highly encourage you guys to check out the HVAC overtime show all right. I was on their live stream. Last week - and I was also on their podcast or the week before last actually and they released a podcast where we kind of talked about a few things, and I've been very, very open about depression and anxiety over the years. We kind of talked about that on their podcast, look up on any the podcast apps like clipped HVAC over time, and you guys will find it download it.

You can hear the conversation that we had. It was a pretty good conversation. The whole thing that I wanted to say you know we're all going through some crazy stuff right now. You guys everybody deals with depression, anxiety, some sort of mental disorder.

Okay, I've been, like, I said, very public about my issues with it don't be afraid to talk to someone. Okay, the the biggest thing that I figured out about my depression and my my mental issues is that I was bottling stuff up and I wasn't communicating with people trust me. It's not worth it communicate. Fine.

You know talk to your wife. Talk to your friends. Talk to a therapist, I highly suggest you talk to a therapist. Actually, if you listen to the HVAC overtime, podcast Adam gave some informaton or Bill.

I can't remember who it was. You guys can say in the chat gave some information about an online. I think it was Bill actually gave some information about an online therapist thing. It was actually sounded like a really cool thing where he just reaches out to someone and he communicates via Skype or something like that.

Some sort of video chat guys you need to talk to people, you need to take care of the in your head, it's so important! If you don't, it just leads to all kinds of things and trust me. I know. Okay from experience get that stuff figured out, communicate with people. Don't bottle that stuff up, don't sit at home, don't you know not talking about it? Okay and when I say don't sit at home.

I understand we all have to sit at home right where we're going through all this crap but try to stay ahead of it right. I feel my depression. I feel it I'm stuck at home, I'm not working! I'm worried about my technicians, I'm worried about my company. I'm worried about everything and it just starts to bottle up and for me the solution is to communicate.

I talk with my wife regularly. I talk to friends, I reach out to friends you guys. I encourage you guys to do so. Okay, it's very important because your mental health is what keeps you sane and if you're not saying you can't make money, you can't fix stuff.

You can't take care of your family, so trust me. Do it reach out to someone talk to someone I've made myself available. Many times and I'll give you my information again, I am NOT a therapist, but hey. Sometimes it takes just someone answering a text message or an email.

Okay, if you have nobody to reach out to, if you have nobody to talk to send me an email, HVAC our videos at gmail.com, send me a text message: here's my number: nine zero, nine. Two, three, eight nine zero. Nine four send me a text message. If you just need to talk it's okay right, but I encourage you to talk to a therapist talk to your wife, your husband, whatever first okay, but I mean, if you have no, sometimes it takes just that one person send me a text message: I'm gon na Type that in the chat for you right now so 9, 0, 9, 3, 8, 909, 4, okay, feel free.

If you just need someone to talk to you, okay, alright, I'm gon na get off of that. One! Real, quick! And let's talk about the two videos that I had last week, so I had two videos that came out the first one was a cooler drawer that wasn't working. It actually happened to be a delfield. It was a base section drawer unit.

It had a pan chiller attached to it, but the pan chiller wasn't part of the system because it was a multiplex system. It was controlled by a rack on the roof all right and when I walked up to the unit. It was a multiplex system on the base section that had one compressor that controlled one two, three four different regions, but it was all the base sections and then all the cold rails were controlled by another compressor. So I went through some diagnostic steps.

I explained it in the video. I ended up finding that the unit had a bad temperature controller. Okay, but again big picture diagnosis right. I don't just stop with that, went through a little bit further found that the compressor suction valve or the suction Reed is a little weak, and it's bleeding by a little bit.

It almost seems like the compressor motor just isn't quite moving as much as it should, because it took a very long time for the unit to do a pump down test on the suction valve or suction, read, and it was a semi hermetic compressor. So didn't really have too many questions on that one. So you know, there's not really a whole lot to talk about with that one. Okay, the next video that I released was the Chi rack blue glycol, chiller glycol cooler.

Now that one, I get all sorts of questions whenever I talk about the like all coolers, okay, so Chi Rack is a refrigerant manufacturer, refrigeration manufacturer they came out, I mean they were, they were around in the early 90s, but they became very popular in the mid 90S up until the mid 2000s, okay, they're still popular but they're, not as big as they were, they revolutionized the industry when they came out with their pants Hillier. Their pan chiller is a cold rail that was capable of maintaining an open, cold rail where cooks can reach into the top, and you grab food out of it, but it kept the food chilled. Okay, the original design was very good and it was very efficient, but it had a lot of breakdowns. Fan motors went bad all the time and the drain lines plugged up all the time.

So the number one issue we had on those things was iced up. Pan chillers and it was crazy, but they were great boxes when they worked properly well, they redesigned that system. Roy Fabian. Thank you very much for becoming a channel supporter, and I'm gon na address that here in just a minute.

Okay, all right so kai rack revamp their design and they came out with a new design where they filled the reach-in cooler with glycol. Okay, it's a mini chiller. The new reach-in, which I made a video on, has a condensing unit and the evaporator is a flat plate, heat exchanger on the other side of the flat plate, heat exchanger. There is a glycol pump and it circulates glycol throughout the region.

So, within the reaching cooler where the food is that there is no refrigerant, there is only glycol being circulated through the unit. So it's a tiny chiller. That's all it is right. Has a temperature controller and the unit cycles on glycol temperature, not box temperature.

The glycol is circulated 24/7, so the glycol pump runs all the time and the temperature controller just checks that glycol temperature and cycles the unit on and off and turns the condensing unit on and off. Okay on that region, we had a bad low pressure control. It really wasn't that difficult. I encourage you guys to go check out the video, not a whole lot going on there.

Now. I did address one thing, and that was when I went up to the unit. The unit was up in temperature right, it was down and we found that when I walked up I out towards the end. I showed the glycol reservoir because as a storage reservoir - and it was way over filled, it had a ton of glycol past the operating line.

It's very important to understand that when glycol gets cold it contracts, okay, as it gets colder, it gets thick and it starts to take a lot longer to to circulate through the box. So when the box was really high in temperature, the reservoir filled up way high because the glycol thinned out and expanded basically okay. So you have to understand that and you have to pay attention to the installation and operating manuals of those books or of those regions, because it says on the the glycol storage reservoir. It's an overflow reservoir.

It says operating range when it's down to temperature and it has a mark. Okay. That indicates that, when it's not down to temperature, the glycol level may not be at that mark because it won't be it'll, be much higher. That's why we have a storage vessel.

It's just like an expansion tank really is all that it is. It allows that glycol to build up so that way it doesn't over pressurize the system. Okay, I'm gon na look at the chat here. I thank you very much for that super chat.

I really really appreciate it. Okay, I'm gon na take a look at the chat here because I have been ignoring it for a minute Ernesto HVAC, our vlogger. He asked me if I am getting busy now. No not yet, but you know I had overtime service call over the weekend for kitchen a/c, no for a walk-in freezer.

I had an overtime service call over the weekend and I had a AC call on Friday and I had another AC call today, but no I'm still not getting busy man we're still slow, it's it sucks, but you know it is what it is. So all right. Let's see what else, let me see what I'm missing here: hmm, I'm looking for caps, lock, I'm just ignoring the stuff: that's not in caps lock! So can I quickly explain how to check the level of a receiver Chris? I will address that right now: okay or let me let me I'll get to that here in a few minutes Chris. I have that on my list of things to talk, okay Alex I'm gon na address that to the site, krama ters.

I have that on my list to talk about okay, I want to kind of go through a few things: Adam Neil refrigeration. Thank you very much for that super chat. That is much appreciated. You do not have to do that, but thank you so very much.

Okay, all right, so I'm gon na address something because of that super chat. I'm gon na some people have been asking me and I'm gon na say this right now: okay, ways to support the channel. I got an email this last week and someone was saying thank you for the videos and they asked me ways to support the channel okay. So, first and foremost, the best way that you guys can support my channel is by watching my video by giving them a thumbs or a thumbs-down, whether you like it or not, it doesn't make a difference.

Okay, the biggest thing - and I know this is hard - is watching the commercials. Okay watching the commercials supports me financially, okay - and I hate to to tell you guys to do that any other creator. It's the same way watch the commercials. It really does help.

Okay, leaving me comments helps me a lot because it gives me material to talk about and things to address. Sometimes you guys leave comments in my videos and it helps me correct. A problem helps me fix something that I did wrong. Okay comments, emails likes or dislikes on the video share.

The video that greatly helps me share it with people that maybe don't know who I am, that could use a video or something like that. That would very much help me. Okay, there's other ways that you can support the channel too. Okay yeah in the show notes of every single video is affiliate links, click on the affiliate links.

If there's something that you're interested in purchasing use, my affiliate link, you can, you can purchase stuff from true tech tools. There's an offer code, big picture. One word: you'll get eight percent off your order, just like everybody else has an offer code right, but I also have affiliate links if you click my affiliate link and you purchase a tool because of my affiliate link, I get a small commission. That's a way that you guys could support me.

You guys need a tool, click, my link, it doesn't cost you guys anything else. Okay, that would help me very much. You can also support the channel by donating to a patreon page by becoming a YouTube channel. Member.

All that information is in the show notes, but again guys. I do not make these videos to make money. Okay, I'm not gon na lie and say that I don't because I do get revenue from it, but I'm still gon na continue to make these the whole point of why I started this channel was to help my own service technicians, and then it turned into this Machine and it did what it did. Okay, I've never even addressed the whole supporting my channel before, but I've been getting enough comments that I figured I would okay, I kind of feel dirty even talking about it, but anyways I'm gon na get off that one.

Now. Let's get to the list of things to talk about. Okay, I will look at the chat. Hvac are wiz.

Thank you very much, but I really appreciate that. Okay, alright one of the things you know that gets me through. We had talked going back to the whole depression and the state of everything. It's weird.

You need to find your thing whatever it is right, bill doing stuff going outside and working on things. Reading books I like to listen to music right. I was listening to music today and it may be, but may not be your cup of tea. I listen to everything out there country to rock to rap to everything, but I was listening to no effects today.

No effects takes me all the way back to high school. It's a high school. What do you call them? Punk band or whatever right? And I just I don't know what it is about - no effects their music sucks. They don't they're, not like amazing musicians, but I don't know, there's something about the the things they talk about in the the beat of the music and stuff that helps me.

Okay, so find your thing whatever it is, and hopefully that gets you through all this weird time right now: okay, what do I think about using substitute refrigerants, neutro dying, okay, so great question personally, I haven't had well I've used a few substitute refrigerants, but right now I still, let's address the elephant in the room. I still use our 22. I have nothing against the alternative refrigerants, but I just my customers are still okay with paying for r22. So I stick to our 22 there's plenty of refrigerants out there that do work, but there's some things you need to understand.

You need to pay attention to the installation, instructions. Okay, I can stress if I can't push this to you enough - do not just listen to the supply houses, there's some good supply houses, but there's also some supply houses out there that give a lot of false information. If there is any supply house out there, that has ever told you it is okay to mix refrigerants. They are flat-out wrong.

You cannot put any refrigerant on top of our 22. The term drop-in does not mean mixing one gas with another gas, absolutely unacceptable. That is not how it works. Now, I'm not saying that it doesn't work, because I know that people have done it and they've got systems out there running with mixed refrigerants.

But you, sir, are not a chemist. Leave that to the chemists. Okay, don't try to make your own refrigerants, because you're just hurting the guy that comes after you that doesn't know what's in there. It just makes for a mess, especially if you use like an a 2l refrigerant that has a flammable component.

You've got all kinds of weird things going on: there don't be a chemist, don't try to mix crap if you're gon na use an alternative refrigerant. I would highly suggest reaching out to my buddy Ralph kind of funny segue how this works out right. So I have Ralph's email right here. I believe I saw him in the chat a few minutes ago.

Ralph works for Honeywell, refrigerants Ralph is a really cool dude and he is always willing to give information on the different refrigerants, the alternative ones that work best. The way to use them and all that stuff, ok so reach out to my buddy Ralph he'll help you out. He'll answer your questions, but I just tell you everything I mean the most important thing is: is don't try to mix refrigerants and pay attention to the installation? Instructions? Ok, if I had to make a choice, if someone put me you know a customer said hey, I want to use an alternative refrigerant. What's the one I should use, I would highly suggest using 4:07 see that would be my choice, but I would do an oil change if I was going to use it as an alternative for our 22.

Ok, all right, so I'm gon na get off that rant and move on to the next one. Ok, yeah, Ryan, Parker r22 is not banned in the United States. All right. They are not allowed to import it and they are not allowed to produce new r22, but we have stockpiles for days of our 22 in our warehouses and everybody.

Ok, I can still purchase our 22. It's not that expensive. As the stockpile goes down, the prices will go up, but we are allowed to use it in the United States. In fact, I used it today, so alright, let's see what Adam HVAC our.

Thank you very much for that super chat Clint. Thank you very much for that super chat. That's awesome guys! You guys are awesome again. I do not I'm appreciative, but you guys don't have to do that.

I know everybody's going through a weird time, so you know I really really appreciate those but the best way. If you guys want to support, my channel is just simply watch the videos watch the commercials. Let YouTube pay me. Okay, but again, thank you guys very much.

Ok, alright. What are the common causes of a bad defrost clock? John deere fan usually exposure to the elements. If it's a grassland, defrost clock, they're susceptible to sand and dirt, and if it's a Paragon, defrost clock, they're, usually susceptible to the screws becoming loose and terminals, overheating and melting. Those are the biggest issues with defrost clocks that I run into so the screws becoming loose on the Paragon clocks, because people aren't doing proper maintenance is and torquing down the screws and on the grasslands and getting affected with sand.

I have no preference I'll use a grassland and and a Paragon all day long there, both of them have a different use so Molly. Thank you very much for that super chat, all right Alex Zapata. What do I think of blue one? I have absolutely nothing bad to say about blue Ahn's product. Okay, I have never used their product.

I have read a lot of documentation and I know some people that say: Oh works. I've had some people that say it doesn't work, but I personally have never used it. I know that they're really pushing hard on YouTube right now. I will say - and I've been very vocal about this - that I am NOT happy with blue ones - marketing right now, if you haven't been in my live streams, lately blue on kind of irked me a little bit when they tried to self promote in my live streams.

Without asking ok, so that kind of frustrated me, but I have absolutely nothing bad to say about their products. Okay, that's all all right. Let's move on I'm gon na get to my list and all the time I get these questions. Restaurants! Oh my gosh! How are you, how can someone? Why don't you people ask me they straight-up, ask me why I don't call the health department on my restaurants? Are you crazy? Why would I call the health department on my restaurant? They pay me it's not my.

It is not my job to call the health department on my restaurants, okay, the health department is supposed to come out and go through these restaurants. That's not my thing all right now, I'm gon na tell you something right now. If you think that my restaurants are disgusting, boy, are you in for a world of hurt, because I honestly I mean the stuff that you see in my videos really isn't that bad? Yes, sometimes you'll see some foods shoved in a corner of a box and there might be some mold or something like that growing on it. But I don't know - maybe I'm just jaded, but I mean it's not great, but it's not that big of a deal I mean it.

It's really not that big of a deal I've worked in some nasty restaurants. I don't work in disgusting restaurants anymore, because I just let him go, it wasn't worth it if you think, what's in my videos is the worst: it's not okay! You should see the stuff that I don't work on. It's gross all right. Oh great question: Christopher Edward tips and tricks for roping things up onto the roof, especially heavy equipment or components.

So safety number one thing hold on my throat is killing me all right. Safety is the number one thing your safety is the number one thing: it's not worth it. A compressor is not worth you falling off a roof. A condensing unit is not worth you falling off the roof.

Am I saying you can't rope a compressor up? No, but I'm saying be safe, okay, so tips to get equipment on the roof, be smart about it all right. If you have a big roof hatch, I've seen people rig up winches I've seen people rig up all kinds of gear and hardware and pulleys and stuff to get stuff up. Personally, I just use a crane. I mean you can get a crane for 300 bucks.

It's not that big of a deal right. I also have a heavy equipment, lift that I it's I've shown it in a couple: different videos, it's a Sumner but like a duct lift, some people would call it, but mine has outriggers and I can lift up to 24 feet and I think I can lift Up to eight eight hundred pounds, I think with it or 600 pounds, or something like that. So if, if I have a roof line that I can set it up safely on, I can you know basically just lift that thing up. It has a hand, crank winch on it and I'll just winch it on up and then just slide it onto the roof and lift it down.

Okay, so the biggest thing suggestion just get good rope get a good hook, make sure you're very safe about it and again, when you're lifting when you're using a crane when you're using a material, lift, always assume the worst be prepared for the worst. That way, if it happens, you're ready, there's nothing. I mean not saying that anybody ever wants to be involved with a crane falling on a building, but every crane lift that I do in my head. I'm thinking, okay, do not get under the boom.

What happens if the load drops make sure keep the load off the building? When he's swinging, I mean you always want to try to think about that. You have safety meetings before you talk with your guys. You explain the way that you rig the equipment up. Don't don't put stuff on top of it that could potentially slide off and hit someone in the head, so you just always want to assume the worst and then that way you're prepared and then, if it doesn't happen, you're good to go right.

Okay, so hopefully I answer your question. If I don't answer your questions and now for thoroughly enough, send me an email, the HVAC, our videos at gmail.com, okay, let's see what I'm missing here, all right: um, okay, I'm gon na get to my list here. Have I ever had a service call, I could not figure out. Of course I have okay.

That was a question that I got the other day. Of course I have because their service calls that I scratch my head on still to this day right. That is what technical support is for and if you're prepared and you're ready, you should have a support team to lean on whether it be friends whether it be colleagues in my situation, I own my own business, but I have friends that I can lean on, but I usually don't get involved in something that I know I won't be able to figure out, okay and the most important thing. If I ever run into a situation that I can't figure it out most of the time when you have a hard time, you just need to stop step back and take a look at the big picture.

I mean I say that, but I mean I'm serious. I mean most of the time you just take, take a break and think about it for a minute. You guys Molly Adam thanks again for those super chats guys. That is awesome.

Okay, but yeah. I mean I'll lean on technical support, but when I call technical support, I'm not calling them to ask them stupid questions. Okay, again, I have my technicians calling me all the time asking me: hey dude. What do I figure this out and I try to tell him don't call me until you have all this information right, because most of the time they'll be able to figure it out once they get all that information ready and it's the same thing goes for me.

I don't call technical support until I have all my ducks in a row. I know all the questions they're gon na ask me: I've got all that information written down and I'm ready to go, and then you know maybe it's something that is om specific and I need tech support for it. Okay, but I'm not afraid to call them. But I also don't want to waste my time calling them for no reason.

So, let's see what else all right, I'm gon na keep going thanks, Molly. I really appreciate that all right how to test the accuracy of the field piece, psychrometer x'. The same thing goes for the test: o psychrometer x'. I don't have the test of ones but it'd be the same thing.

The the field piece psychrometer x' are not field adjustable. Okay, so there's really no way to calibrate them in the field on the psychrometer x'. I imagine it's the same thing on the test. Doze, I can't say a hundred percent, but I'm pretty sure it is okay.

What I would suggest is, if I'm trying to verify if they're, accurate first off the field P strike, psychrometer x' are highly accurate. I test them all the time and I have yet to find a time where they're not accurate and I'm currently using a set that I've had for over a year and they work just fine okay. I will usually test them again against a known good temperature. Okay, first off, you cannot put the field P, psychrometer x' in ice water, like you, can with a normal thermometer, so you just got to put them.

What I would suggest you do is, if you have, I mean a another psychrometer that you know works properly. The hard thing is is going to be the humidity. The humidity is going to be a difficult one to verify for sure right, but the temperature that's really easy. The dry bulb temperature just find a known thermometer.

That's calibrated dip that in ice water and then compare it to the field piece. Psychrometer, look at the dry bulb temperatures. That's the only way that I know of to verify accuracy. I have yet to find one of my field piece, psychrometer x', that is incorrectly working, but I would also suggest that you reach out to feel piece and ask them see what they have to say all right.

Let me see what else we got Jose sent me an email talking about how he was about to get hired on with the company, and then kovat happened. You know hold on just one. Second sorry, my family cat was crying at my door. Cat doesn't know that.

I'm doing a livestream come on um, so Hosea tasked me. He was just kind of telling me how much of a bummer it was because he was trying to get a job with a company he finally got hired on and then kovat happened and they didn't hire him. Okay, we are all going through that and I don't have any advice for you, Hosea, I'm just in general, just so that you know we're all going through that kind of stuff. There is so many people that are laid off right now.

Things will get better things. Will pick up - and this is gon na segue into another question - let me see who wrote it Spencer had asked me: where do I see this trade in 20 years? Well, I see this trade thriving, because this trade is never gon na go away. Hvac and refrigeration is always going to be around, but where do I see it in 20 years I see a lot more technology integrated into our trade, but the fundamentals will still be there. Super heating, sub cooling will still be there.

Compression will still be there. I don't see us going completely to magnetic refrigeration, compressors or anything like that. I mean you know those are gon na become more and more popular, but that's not gon na, be everything. We're still gon na have basic systems out there.

We're still gon na have basic electrical systems, but there's gon na be some new components in there. I think we're gon na be going to a lot more of digital wireless stuff. You know our tools are gon na go. Wireless manifolds are already going wireless, and you know most of our tools are so, but this trade is still gon na, be here, it's totally worth it.

If you haven't already get into the trade, you will not be disappointed as long as you're willing to work hard and bust. Your butt, you're gon na make good money and you're gon na be good. Ironically, I was just talking, I'm not gon na say who, but I was just talking to someone about their. You know a college, that's looking for instructors and it's kind of sad because they're looking for instructors for the HVAC program - and this isn't one college in particular.

This is all you know, most of the colleges out there they're looking for instructors, but they require degrees like an a a or something to become an HVAC instructor. I understand that on one side, but I don't understand it on the other side, because you I mean a college degree is good, but you don't need a college degree to be in this trade. You can make damn good money without a college degree, so yeah anyways, I'm not even gon na, go too much further down that one. What is the most common compression ratio and displacement for reciprocating? Compressors moly? I do not know the answer to that question.

The compression ratio is going to change, I mean, depending on the refrigerant pressure and the saturation temperatures and everything so all right any chance. I can turn the mic yeah if it is high. I will definitely turn it down hold on just a second. How about that? That should go a little bit lower.

I didn't realize that sucks. I'm sorry! I didn't realize that the gain was high. I can also move back a little bit too sorry about that guys. Hopefully that's better.

Let me see what else and let me see what I got on the list here, all right winter charge. This is one that I'm getting a ton of questions. Let's, let's make sure our is the gain okay, where I have it set right now guys, because I turn my mic down a little bit before I go any further. Okay, loud and clear, it's not clipping anymore clipping, if you guys don't know, is when it like kind of pops and sizzles in your ears.

It's like the might. You know that the computer can't handle the audio. So it's better. Okay, now I'm not peeking.

Okay, all right cool all right, so I'm gon na go ahead and go on with this. So anytime that happens, guys, don't hesitate to tell me sometimes things happen and actually what happened was my mixing board. I updated it. I have the road caster Pro and I had done a firmware update and I knew that crap was gon na happen, so anyways all right, cool, so winter charge.

So I I know everybody's sick prime time, if you're in here I know you're sick of me. Talking about Headmaster's head pressure, control valves in winter charge - and I know many other people are too but there's so much misinformation and people just don't understand it. Okay, so I had several questions about winter charge. So, first off, if you have a tube and fin condenser, I'm not going to go too crazy into this right now, because I have plenty of videos and livestreams to cover it in depth.

Okay, but if you have a tube and finned condenser that has a head pressure control valve, your best bet is to follow the spoor'ln 90-30. One method is a tech document on their website. You can go to spore Len calm and they have lots of great information on there. It will explain the proper charging procedure for a head pressure, control valve on a tube and fin condenser okay now, but there is a time when that method won't work.

Okay, it's hard sometimes for me to express it, but it usually has to do with service. It's usually when you know there's just a weird time when you go up to a system and you don't know how much gas is in it, but you know that it's low. How much do I add? How much has it lost it's kind of a pain in the butt? There is a couple rules of thumb. The biggest one is to fill the system up with a maximum amount of refrigerant.

Now this can be dangerous, and this can be wasteful for the customer too. If you put the maximum amount of refrigerant in that system - and it has a massively oversize receiver - well, they're gon na have tons of refrigerant that they don't necessarily need in that system. But on the flip side, when we're technicians out in the field, sometimes we just have to get the system properly charged and we don't know how much refrigerant it needs. So what we can do is we can put the maximum amount of refrigerant in there in order to do that, what you do is you would fill the system up when it's pumped down to about three-quarters of a receiver.

Okay, it's a it's a storage vessel for refrigerant, same thing as your refrigerant tanks. In your van right, when you have a drum of r22, let's say: there's 30 pounds of refrigerant in there, but the drum weighs 36 pounds because there's room for expansion inside that cylinder. The same thing has to happen in the system. If you don't have room for expansion, when the temperature goes up, the pressure goes up.

That can' is going to explode. Okay, the refrigerant system is going to explode. Now we have safety devices in the system that prevent that, but I'm going off on a tangent again, the maximum amount of refrigerant that you can put into a system that has a receiver and a head pressure control valve is about three-quarters of the receiver. Okay, you got ta leave room for expansion, so how can I tell if there's three-quarters of the receiver when it's pumped down well, what you can do is you can take? You can pump the system down the compressor shuts off.

All the refrigerant is stored in the receiver and the condenser. You can take a heat producing device. I'm not gon na tell you, which one some people in the chat can tell you. Everybody has their different methods, but you have to use a heat producing device that does not exceed the safety limit, temperature of the storage vessel or the receiver there's a soft plug on there.

It's usually stamped on it 430 degrees. If you overheat that soft plug to 430 degrees, it's gon na blow and vent the charge out, okay, so whatever heat producing device you use, cannot exceed the soft plug temperature or the the pressure relief devices temperature. When you do that, and you heat it, you pass the heat producing device up and down the storage vessel or the receiver. When you take the heat producing device off, you can take your fingers and you can start moving them up the receiver in the moment that it gets hot.

That is the liquid level below that in that receiver, because the vapor there's always going to be vapor in that cylinder right, the vapor, that's where the heat is at the liquid, isn't gon na heat up as fast. So when you run your fingers up and down, you can feel the liquid level. Now you have to understand something. There is danger in that you have to be careful.

You have to use common sense now, the other part, the person another one had asked me. What is the proper refrigerant level on a receiver pump down that doesn't have a head pressure control valve? Well, I don't know because every receiver has a different size. The dip tubes are all at a different dip place inside the receiver. So, on a system that doesn't have a head pressure control valve, you just need to clear the sight glass, okay being careful that you understand that a sight glass is a window into the system.

At that point in the system it doesn't necessarily mean it's fully charged. There's there's all kinds of variables in there, but I'm not gon na go off on a whole, crazy, tangent on sight, glasses right now. Okay, if it doesn't have a head pressure control valve, then you just simply clear the sight glass once it's within about five degrees. A box temp before it satisfies and you should be good to go.

But if you have a head pressure control valve, you have to add that extra winter charge and that's when we would fill the receiver up. But, first and foremost, if we have a tube in fin condenser we're going to use the spoilin 90 30 one method, you're gon na lean on the manufacturer to find out the proper refrigerant charge for that system. Okay, hopefully, that answers that, if I didn't answer it send me an email, the HVAC, our videos at gmail.com. So why do refrigeration systems pump down? Well, there's a couple different methods: Ike, one of the main reasons is to prevent a flooded startup.

Okay. So what you? Don't want to do, is you don't want to have all the liquid refrigerant migrated down to the evaporator in the off cycle and then when it turns on the compressor sucks all that liquid refrigerant back up to the compressor and the compressor gets a big ole blast Of liquid refrigerant and that can cause problems, other things would be to help the system startup easier. To prevent. I mean it really doesn't prevent oil migration, but I have seen it written that it prevents oil migration, but really it's more for a flooded start to prevent a flooded start.

That's the biggest issue for a pump down now. There's another method. If you have a multiplex system, so in my recent video on a delfield cook stores, I had a multiplex system, I had a reach-in cooler. I actually had for reaching coolers that had one common compressor, but they had their own independent temperature controllers.

So each separate box is able to maintain its own temperatures and turn on and off whenever it needs cooling for that infinite box. In that situation we have to have a pump down circuit, because each box has to be able to operate on its own. You can't just have one cylinder valve because then you might freeze the product in one box and not get it cold enough in another. That's another reason why we need a pump down, because when you have a multiplex system or multiple circuits on one compressor, you've got to be able to cycle each circuit independently.

Okay, hopefully that answers your guys's questions. Hvac, our novice are stainless steel, heat exchangers, encoded, coils worth it. Your pool stores eat them in like one to two years. If your pool stores didn't have stainless steel, coil heat exchangers and coated coils, they would probably last less than a year.

So your biggest thing is: is your environment and the chemicals that you're using around in those pool stores, is eating away even with a coated coil? But if you didn't have a coated coil and you didn't have a stainless steel heat exchanger you would, it would be changed even faster. So, yes, they are worth it they're very important. In my opinion, all right, let's see what else is a read valve the most common valve system for reciprocating reciprocating compressor, no, because a scroll compressor well yeah. I guess I think I think the answer to that is: yes Molly.

I think so yeah. I think a reed style valve is the the most common yeah for a reciprocating yeah. I would think so ever done any bulk tank refrigeration. No, I have not all right what would cause a freezer to stay pumped with a new install to stay pumped.

I don't know where you're going with that question Willie and I need some more context of that. So please send me an email and give me more information. I feel, like your question, is going down a path that we're gon na have a dialogue back and forth. So that's that's a good one for an email, HVAC our videos at gmail.com.

Okay, what's the biggest advice I can give to grow my company l-boogie? I am not the person to ask that question because I keep my company from growing. I have had a bigger company and honestly when I get that many service technicians, it's too hard to maintain the quality of service and the customer service. So I keep my company small. So as far as growing honestly, I'm not the person to answer that.

I would reach out to my buddy tersh Blissett at the service business. Mastery podcast did he just change the name. I think he did just change the name. No, he changed the name of his company, but I think his podcast is still called service business mastery.

I think reach out to him and he you can find him on YouTube. He has all kinds of great information on growing your business and that kind of stuff. So what's my opinion, when I come across DIY installs, I mean it is what it is. If someone did it themselves, I'm gon na be frank, and I'm gon na be honest with them and tell them like look in order for me to very you know, warranty this or tell you, I'm gon na tell you what's wrong and you're gon na need to Fix it, whether you fix it or whether you have me to fix it, if someone wants to do something on their own good for them, but if they don't do it right, then I'm not gon na work on an own it.

No so do reciprocating. Compressors have high pressure bypass; yes, they do most of them like. I know the Copeland ones do for sure. They have high pressure safety reliefs inside that if the pressure gets too high they'll let go and they'll bypass the refrigerant into the low side.

So all right, I'm gon na get to my list of things to talk about here. Um. I had done a video a long time ago about a dishwasher exhaust fan, and someone had left me a comment because he was bringing up a good point about the dishwasher exhaust fan oftentimes. They are connected to a dishwasher and the exhaust fans themselves will be interlinked into the dishwasher.

It's very important to understand the sequence of operation, because if a dishwasher exhaust fan is not working, it may be that the contactor or the relay inside the dishwasher is not telling it to turn on. That's a very common thing with that being said, you have to be very careful not to open up a dishwasher that someone else owns. For instance, ecolab, does work for a lot of my restaurants and Ecolab leases, the dishwashers out to my restaurants, oftentimes. We will have a bad relay inside the dishwasher and technically I am not allowed to open up the control cabinet, because that is a collapse property now, on the flip side, most of the time the Eco lab technicians, they're, not service technicians for HVAC, and they don't Even know how the relay works, so I will I've actually met.

You know some of their technicians, I'm not just saying ecolab, just general dishwasher text in general. Sometimes they don't understand how those contactors or relays can work and I'll have to change it while they're there. Just so that way, they know ok, but you just need to be cautious about opening up equipment that you have no business opening up, especially if the customer doesn't own it same thing with like ice machines and different things like that in ovens. Well, ovens.

I don't think they lease, but ice machines. Restaurants, Elise, sometimes and they'll - have contracts with whoever and if they call you out to service it, you could void warranties. You can cause all kinds of problems, so be very cautious about opening up equipment that you have no business being in, would I mind explaining my method of pumping down a resident, chill condenser, Frank Bradley. First off, you need to be very careful when you're pumping down residential condensers okay, because if it's a newer, microchannel condenser and it has a really long line set past the manufacturers recommendations, there's the potential that that system could be overcharged with refrigerant more than the maximum Amount of refrigerant the manufacturer, recommends, if you try to pump it down.

Okay, you can run into some problems. Now. I'm gon na explain something here. When you're pumping down a residential, condenser oftentimes, you will shut down the liquid line coming out of the condenser okay.

When you shut down that liquid line, you are no longer seeing the true high side pressure of the system, depending on the type of valve. That's on there. Theoretically, that systems pressure can get so high that it can blow a pressure relief and you wouldn't even know, even if you still had your gauges on it, you need to be able to understand how a service valve works and where your gauges are applied to it. Okay, also liquid line service valves oftentimes, will have a lower pressure not by much but a lower pressure than an actual discharge line.

Service valve so be very cautious about pumping systems down. If you don't understand how the service valves work, especially if they're micro Channel condensers so a lot there's a lot of you know information out there saying you can't pump down a micro channel condenser. Well, that's not actually true! You can pump down a micro channel condenser if you're properly monitoring the system pressures while it's being pumped down, but you need to know when you're actually seeing a true discharge pressure, a true liquid pressure. You need to be very careful with that.

So if I was to do a pump down on my own condenser that I have in my house, it's a tube and fin condenser, I would go out there. I would put my gauges on it. I would close the liquid line service valve. I would let the system continue to run until the suction pressure gets to a low pressure.

Then I would shut the system off close. The suction valve recover the remaining refrigerant in the liquid line in the suction line, and then I would cut the system open and move the condenser to the side. Again, though, talking about pressure vessels need to be careful, because how do you know how much refrigerant is too much refrigerant in that condenser? You no there's nothing to to heat up with the receiver to find out where the liquid level is right. You can, in theory, have an overcharge condensing unit and pump it down, and then you set it to the side and a pressure relief can blow ten minutes later, because it's 110 degrees outside.

So the best way is to close the liquid line service valve. But you need to be monitoring the high side pressure, the true high side pressure, while it's pumping down then close, the suction line service valve once it gets down to about five or six PSI shut the system off recover the remaining refrigerant in the on the other Side of the service valves in the line set and then go about your way. So hopefully I answer your question for you there, but best way to find a job. If you're laid off everybody's looking for jobs, man guys there is a service company local to me.

Actually, I don't know, I know, there's someone in here that works for them. I think I'm almost positive, I'm not gon na well yeah, I'm not gon na name the service company, but there's a service company local to me that had about 200 service technicians.
