Ah, it's time to chill out and get ready for a mediocre. Qa live stream if you're old enough grab yourself your favorite adult beverage and if you're not stick with apple juice, put your feet up and relax. If you have any questions, feel free to ask them in the chat and now, let's queue up the intro music yo. How are you guys doing oak or hopefully, you guys are doing well yeah? Sorry, I just got distracted for a second, but I'm Chris welcome to the HVAC.

Our videos live stream for those of you that are new here, thanks for coming thanks for checking it out, I'm guys that come all the time and, ladies that, come all the time. I'm addressing these these chats like with an intro and stuff because we've been getting a huge influx of new viewers and new subscribers, and so I know people are kind of curious what's going on here, so I'm an HVAC our service technician here in Southern California, and I started making these videos to help my employees, the first two videos I never intended making public. You know. I've said this story a million times.

I finally hit the public button and it turned into this machine that it is today - and you know it's it's fun. I never expected it to do what it did and I probably don't treat it quite like I should, but that's ok, because I'm a peculiar person that does things my way I don't really bend over. You know I don't do these per se for the money. Don't get me wrong.

I do make money from them, but that's not the whole goal of it. It's kind of been something that I'm just I have fun doing and I'm passionate about and yeah. So I'm an HVAC, our service tech, I've been doing it and since 2002 officially, but I grew up in the trade working for my father, so it's kind of like almost all my life. You know it's.

It's just been a thing. I work in restaurant refrigeration and air conditioning and I already said in Southern California, so all I've ever done is restaurants. I've never done supermarket work or I've never done residential. Besides just helping out family members and different things.

So I don't claim to be the person that knows everything, because I don't I try to be as honest as possible. I do know a few things, but I also have made a lot of mistakes over my career and I try to show those mistakes as much as possible and or explain. You know reasons why you shouldn't do something because of a mistake I may have made or witnessed, or something like that, so I'm just trying to help the next guy. Ok, that's the whole point of these is just to share the little bit of knowledge that I have so.

Thank you guys so very much in the chat. You guys are chatting like crazy right now and it looks like we have a new members. Actually, since the last stream we've had a lot of new channel members, new patreon members - I probably don't acknowledge you guys enough, but thank you guys very much for doing that. I do not expect it.

You know it's. It's really cool, though so thanks so much. It does help out a little bit. I'm gon na address the elephant in the room.
Everybody's always asking me all the time you know hey. When am I gon na sell the shirts? I've got a giant pile of shirts behind me in hats and stuff they'll be coming soon. They're all back there, I'm waiting on someone there they're working on a website for me right now. I've seen two rough cuts.

I'm I'm super stoked because I think it's gon na turn out the way that I want it to like. I said you know: I've been going through this and you know if I've approved edits and different things, so hopefully it'll be coming soon and I'll make it available. You guys will all know. Okay, everybody um they'll make it.

You know known across social media and everything. So Greg, thank you very much for becoming a supporter, but I really appreciate it so um yeah. So as usual, I got a bunch of things that I want to talk about. I want to talk about the last two videos that I had and then hopefully I can address some questions in the chat as usual.

Guys, if you guys do have questions, please put them in caps-lock, okay, there's gon na be there's a ridiculous amount of people already in the chat. So there's gon na be questions I don't get to. If I don't get to your question, send me an email HVAC. Our videos at gmail.com you can keep trying to repost your question until someone tells you to stop.

One of the moderators are myself. Okay, most of the time, I'm pretty good at saying hey. I can't answer that. One today send me an email, okay, HVAC our wizz.

Thank you so very much for that super chat. Okay. I really really appreciate those guys but um yeah, so alright, let's get on with it. So this last week has been a pretty good week for me, the following week, I should say I mean leading into today.

It was pretty good. Today's kind of Monday's are always kind of stressful for me, because Mondays are usually one of our most unpredictable days because we usually have calls from the weekend and then, of course, I decided to start doing these live streams, and I think I've been doing these live Streams for almost two years now, I think I think I'll have to go back and look and see where the the first one, but I've been doing in Mondays, consistently for a long time now, which is kind of strange because it you know, I usually have to Get off work early to be home in time to get prepped for the stream and set everything up and everything so yeah, but yeah, it's been a good week! So far it got a little hot last week for us here in Southern California. So I think we've barely just broke a hundred last week, maybe just right below 100. This week is cooling down a little bit.

I think today was 92 ish or something like that. So it's not too bad. You know coming out of this kovat thing. Things have been getting a little bit better, you know, stores have been sorry, I'm texting something right now, stores have been.
Restaurants have been starting to open up nc a fire and security thing, our knack of fire and security. Thank you, so very much for that. Super chat but but yeah restaurants are starting to open back up there, pretty much all in full swing. Now you know you know they have to have limited capacity in their dining rooms, but I think in San Bernardino and LA County we had a.

We had some restaurants be able to open up their bars, which is which is a plus, because when the bars can open up that, definitely you know adds to sales and - and you know then restaurants can. The whole goal is for the restaurants to make money right. That's the most important thing so hang on I'm adjusting something real, quick but anyway sorry I got a little distracted trying to adjust my audio level. So hopefully you guys can hear me.

Okay, I think my audio levels were a little bit low, but I adjusted them a little bit so make sure you guys tell me if I'm clipping at all, okay, so so yeah, the restaurants are all kind of open back up, which means that the service calls Are coming back in, which is good, so you know, I would say that before kovat, six to nine service calls a day is what we would get not necessarily do, but that's what we would get as a service company and we went to all the way down To like three a week during the Cova thing and it's kind of picking back up so right now, all my employees did come back because we had to lay everybody off for a couple weeks. While the whole kovat thing was happening, we did bring them all back and we're all starting to get to work. So I would say right now: we're probably getting four to five service calls a day. Maybe six you know, but that doesn't mean we get those all done every day.

So that's what keeps us going you know, and then we have calls from the weekend to different things like that, and then I always have projects I'm working on, or you know weird particular things that I'm working on you know. That's why people always ask is: are my video is always so chaotic and crazy they're, not always crazy, like that, my calls aren't, but for the most part I take the calls that I know are gon na be difficult. So that's why I film them. You know that way.

The whole point of these is to show to my employees and then obviously you guys get to see him as a bonus, and you know so it's it's. I do get some difficult ones, anyways, alright. So the two videos that I released this last week, the first one - was some overdue cleaning, and that was just a service call basically actually a service call on a reach-in cooler and that's something I wanted to talk about. So I know that a lot of these restaurants haven't had preventative maintenance service, some of them since, like February okay, because of budget cuts and different things and then kovat hitting so when I go out on a service call so in some overdue cleaning.
Video right and that one I was going out on a service call for someone, Xerox, runner. Thank you so much for becoming a channel supporter, but so I was going out on a service call for a region that happened to have a compressor on the roof. Now, the region, I knew had an electrical issue, but because I always look at the big picture, I knew that the refrigeration rack was gon na be dirty. So I took that opportunity.

I went to the customer, I said: hey look, I'm working on this reach and it has an electrical short, but I noticed up on the roof. The rack is really dirty. That's gon na start to affect the box in order for me to walk away from this comfortable, I need to clean the rack and they said go ahead, so I utilized that okay, of course, keeping the customer in the loop when it comes to anything like today. For instance, I went out on a service call to a customer, I don't normally service, they had a water leak and I went up on the roof and I noticed that the drain was plugged up.

So I blew out the drain. Real quick just took me a second. I noticed the belts are loose, the condensers dirty the evaporators dirty. I brought it up to the customer instead of just going in there and solving the problem right or the symptom.

I should say you know I went in there and said hey. We need to clean this unit up and they said go ahead and then I said you have five other air conditioners. Do you want us to clean those up too yeah? Do it? Okay, so they're? Not necessarily calling us for preventative maintenance, but I'm able to get preventive maintenance wall on-site. Okay, I always walk the roof.

Look at the ACS. If they're Lennox units check the codes, you know look for any things. Condenser fan motors running things like that, so I'm always observant. I'm not ripping the customer off, I'm keeping the customer in the loop, the entire time and just basically giving them everything.

You called me for a water leak like today, but here's some other things, and if we don't solve this problem, you could potentially have an AC call. Next week you can have a nice tub coil, you can have all kinds of things that can lead to more headaches. So let me take care of it now you know and they bring it up and they say yeah so, but the overdue cleaning video. That's what that was okay, and I like to show you guys the little tips that I use.

You know for cleaning and different things like that. I love that wand that I showed in that video. I always use that and guys I'm not really paying attention to the chat right now, but I will get back to it. So, just if you're posting something you want me to address, just keep putting it in caps lock and keep reposting it and I'll get to it.

Okay, the next video that I had was the beer is pouring warm, and that was a glycol unit. That was a return visit. Not us not a call back, but I worked on that unit about a year and a half ago that exact same unit had a refrigerant leak. This time they called me out, and it had a bad temperature sensor for the dick cyl controller, okay, which I ended up.
You saw I went and put a temperature, our temporary temperature controller in it, because I knew the customer needed the unit up and running. I had to order the special sensor from Pearl ik so went ahead and got them operational temporarily by thrown in and mechanical temp control. It ran for a couple days and I returned and put the new sensor back in and all as well a customer's happy. Everything is good.

I cleaned up their units again, big picture diagnosis. You know looking at everything, I don't go in there and just slam it out. I like to spend time again keeping the customer in the loop and talking them through everything, okay, so the glycol unit. I get a lot of questions about those glycol units or a power hack or meanie chiller beer line, chiller, there's a bunch of different names that people call those, but there's really not too much crazy to those units.

Okay, essentially, it's just a chiller that the the chilled glycol that we use wraps around the beer lines separately completely. It's not mixing with the beer wraps around them completely just to chill the lines when they run underground or above-ground wherever they're gon na go. They just keep them cold from point A to point B: okay, that's all that they're doing they're trying to reduce foaming beer, because when you have foaming beer, you have lost beer sales, basically, okay. So, if your, if a customer, if you're drinking one of those piss beers and you pour it and it's got three inches of foam or head on it - you know the customers not going to be happy.

So you end up pouring a bunch of extra and that foam is just wasted. Beer just goes down the drain, so if we can keep it chilled to the right temperature, so they can get the correct pour then they can save money. You know and potentially make more money, alright, so those those little power pack units or glycol units, they are very important, okay, same concept. If that was like a processed chiller, you know going to some medical equipment or some manufacturing thing.

It'd be kind of the same thing: okay, so let's take a look at the chat here and see what I'm missing and see if I'm missing anything important, remember to put your questions and stuff in caps lock. Is there anything in the HVAC industry? I would change interesting question. Adam Adam Neil asked that if there is there anything that I would change in the HVAC industry, I mean if I had a magic wand and I could magically make more employees pop up. That would be helpful because we're all looking for new employees right, hmm.

What else would I change? I don't know you know: government regulations Adam. I know you're in Europe, but government regulations they're just ridiculous. I wish that they wouldn't implement regulations before they figure out how manufacturers are gon na, follow those regulations and different things, because it seems like the government again, not getting political, but I'm sure it happens everywhere. It seems like the government comes up with a solution that they're gon na get rid of this refrigerant before everybody can really figure out what they're gon na do you know that kind of stuff, but I don't know I'd, have to think about that one.
A little bit more Adam, so do me a favor if you think about a semi, an email and I'll try to think about that one and maybe address it on the next stream a little bit better. So, let's see what else I got going on in here! Um, let me see uh, am I go ahead and take that one out of there all right, oh great, so big Nate, saying that yeah he's a former draft beer, tech and he's saying 41 degrees loses the co2 in its solution and it appears as foam. That's see there, you go, I'm not a genius when it comes to the beer stuff. I don't touch the regulator's, I don't touch the co2 or the nitrogen, depending on which type of beer.

It is that's not my thing. All I'm doing is is keeping it cold, but yeah it's really important because beer sales, you know, that's that's a huge thing for restaurants. So, let's see what else? Okay, I'm gon na go ahead and take care of that real, quick. All right, um, all right, adonis, you said you're in the middle of your GED locator test right on, but alright yeah.

So i don't test the beer. That's that's a funny comment that i get on a lot of my videos as people asking me. If i'm testing the beer, no, no, i don't. I mean I be honest with you.

If I asked a customer, they'd probably say yeah, but now I don't I just leave it be I'll, usually have the customer I'll waste some beer, sometimes so, really cool tech tip. If you're working on beer right or a draft or a glycol unit - and you just repair it - it takes a long time for glycol systems to come down to temperature. Okay, especially if it's been down for a very long time, if the beer lines are low, are really warm going through the attic or down below it's gon na take a long time for that draft beer to cool down in those beer lines, because it's not in A walk-in okay, it's out! It's that stuck beer between the walk-in and the taps, so oftentimes. What I will do is bring up to my customer and say: hey if you're willing to waste two to three pictures of each beer.

I can get you selling beer within 20 minutes, okay, and what I mean by that is, after you've done the repair, if they clear out the beer lines from the beer walk into the taps. Usually it's about two to three pictures of each beer and just pour those down. The drain. They'll have 40 degree beer in no time, because what takes the most time is cooling down that unrefrigerated section of beer lines so will usually do that I'll have them.
You know waste a couple pictures if they're willing to some customers aren't depending on some things, but you know when they have a really busy Friday night and they need their beer sales. You know and they're pissing off customers they're willing to throw a couple pictures down. The down the drain for sure, so that's a really cool tip. If you guys, haven't already figured that one out that'll save you a little bit of time and help to bring the system down to temp but obviously don't be walking into a bar and pouring beer down the drain without talking to the manager.

Okay and don't ask a bartender either you always ask the manager because they won't be too happy if they don't approve of that kind of stuff, so all right, which service valve, do you open, first suction or liquid th. You know, honestly, I don't put a lot of thought into that one th, you know I it's it's that weird question. Honestly. It's never really been an issue for me, so I really don't put a lot of thought into it.

The biggest thing about which service valve to open you know, there's there's a bunch of different theories. There are you gon na wash oil out of the system, and you know different things like that, but I really don't put much thought into it. I guess if, if you had to ask me right now, I'd probably open the liquid line first, but you know I, I really don't put much thought into it. So alright, what's the worst job I've ever had and what did it involve the worst job you ever so the worst job I've ever had was actually an installation job.

I was doing a job for okay. This whole thing was a disaster. I think I've talked about this before, but this whole thing was a disaster. It was on an Indian Reservation.

I've never done work on an Indian Reservation and I've heard some good and bad things about working on an Indian Reservation. Okay, so last minute a third party contractor called me: okay, so this guy basically quoted this job and apparently didn't have the licenses to be able to do the work in California. So he was subbing the job out to me. So he and it was - it - was part of a giant construction project working under a general.

I was not working for the general. I was working for someone that the general hired okay, so the red flags were already there. But I went to him and I said hey: this is what we got to do. They were installing refrigeration equipment all over the place and they wanted me to insta hook up the refrigeration equipment that they already had.

Okay, so I went to go. Do a site, inspection - and I saw this job was giant okay and I was a little bit eager. This was probably about 12 years ago. I was very eager.

I really wanted to do it because it seemed like a cool challenge. Okay, but everything unfolded. It just got worse and worse as the job went on, so I went into the site inspection. You know.
I asked all the right questions where's this equipment going. Can you take me and show me they? It was. It was on an Indian Reservation in a casino, so they took me on to the casino they had to walk through corridors and corridors. They showed me all this different stuff.

This is where this is gon na go. There was nothing there, they were building the building. Basically, so they were like showing me plans and everything, so they started showing me all these plans. It had models and serial numbers.

So I took pictures of all of that started: writing down all the models and serial numbers. When I got back to the shop, I started looking the equipment up and then I realized there was some major mistakes. Design-Wise in this equipment, the equipment wasn't sized correctly. It wasn't big enough all sorts of things.

I ended up getting the manufacturer who expect all the equipment out, and I ended up talking to them and saying look this condensing unit that you're sending out here. You know, there's not a big enough receiver on it. It's not sized correctly. It's not the right horsepower.

Like I was going through everything because, basically, even though I didn't sell it to him - I was gon na, be the one installing it and I knew it was gon na become my headache. Of course, I would have been able to bill for it, but it's just what it became my headache so started going through that that was another red flag. I was redesigning their designs, then they told me you know when I asked him. Okay, I need to you know, get a scissor lift where that blackjack table is at so you got to move the blackjack table, they were like.

We can't move a blackjack table and I said well you have to because I have to work right there and they said. Oh, you need to come in at nighttime. So then the job turned into a nighttime job. Mind you.

This job was gon na. Take five people: okay, at the time that was my entire company all doing night work at a casino, and it was probably gon na be about a five day job. So there was another red flag, but we worked through it. Okay, ordered all the equipment had them redesigned everything.

I was getting ready to run line sets and then the time came to schedule the job. Then I went to go onto the job site and they they're, like you, have to take safety meetings and okay, fine just hold it just seemed like it just kept getting worse and worse safety meetings, and you know signing crap off. We had to wear stupid safety. Vests, whatever it's okay, you know, but it just kept adding up so finally came down to it.

We went out to do the job. Nobody was there. I had scheduled everything with the general with the the people from the casino and all that crap and I went to go there. None of the tables were moved, they they were not ready.

For me, it was a disaster. So at that point oh - and I forgot to say too, I had rented a scissor lift. Okay and the scissor lift they delivered was broke. It didn't work, I had driven it to a far place on the casino property and then it stopped working.
So then we had to get it back to where the diesel truck from the rental company could come and pick up the scissor lift. Then they had to bring me another scissor lift, and then here we are now the night that I came out to do the work. We're already all my guys are there. We've got all the equipment, we're ready to start piping stuff in.

We were gon na run in all kinds of line sets and they weren't ready. For me, there was nobody there, they didn't have tables moved. Everybody was playing dumb, they didn't know what was going on mind you. I scheduled this with multiple people.

I had emails and phone conversations so by now we are about three days into the job of just work from me sitting in the office, doing site walks and everything, and we still had five days worth of work on top of it. Okay, labor wise with all my employees going through all the safety meetings and everything I was probably a good five to six hours per employee, plus all my time, which was ridiculous amount of hours, and so that night I decided I was done it pissed me off Again, I was working for it. I was a subcontractor, it was ridiculous. I didn't tell anybody that night.

I sent all my employees home. I loaded up all the equipment on my truck we're talking 20 foot sections of pipe. I had pipe hanging off both sides of my service truck. I loaded it all up on my truck and I left the job.

I didn't tell anybody. I was gon na leave the job and the reason why I didn't tell anybody was because I've heard some horror stories working about about working on casino property and how the rules don't apply there, and once you bring materials on the job site, they own them. Like weird stuff, yeah, cuz, there's different they're, definitely technically a different nation right, they're, a sovereign nation or whatever. So I loaded everything onto my truck and drove off that job site.

Without talking to anybody - and I called my person that I was working for the next day and said - we're done we're done - I'm not doing the job. Sorry, I ate all my labor, I think when we broke it down, I think it was like $ 3,000 worth of a billable labor that I ended up just I wasn't even gon na fight him for it. I just said we're done. We just walked away from it and I took all my materials back to the supply house.

Luckily they took them all back and I learned no more construction projects, I'm done with new construction. It's stupid, it's just a headache. For me, I'm not set up and geared for that. That was probably the worst job I ever did.

It was gon na be a fun one too, but it was just the worst job just a nightmare, but there's sometimes you just got ta. Let it go. You just got ta walk away and just write it off as a loss and say I'm done so there we go. That was a nice long thing um, let's see what else we got in here.
How are things going in California California's doing pretty good? It's getting a little bit better. Restaurants are opening back up, I'm in Southern California. My main counties that I work in the three counties - Orange County, San Bernardino, County and Riverside County - and I do the tiniest bit of work in LA County they're, all pretty much opening back up. I think Jim's just got the go-ahead to open back up.

I think they say we're in Phase three or something so things are getting a little bit better. The economy is still messed up. The freeways that the traffic still isn't there, yet so it's getting there, but the fact that the freeways aren't jammed with traffic means that majority of our economy probably still isn't working, which is kind of sucky all right see what else see if I'm missing anything in Here, let's see, is there any reason I tend to jump stuff out live you usually turn equipment off and jump things out to avoid shorts. You are wondering if I had a reason.

I do it the way I do it nan de yeah. First off, you have to be very careful and understand what is going on within your equipment. If you're going to be jumping things out, it's very important: okay, don't ever push content, there's and I've said this so many times. I've learned the hard way, especially and I'll quote it cuz.

I've done so many videos and different clips Linux package units that have a VFD that has a bypass contact or, if you push that bypass contact to it or actually, if you push in the in door, blower motor contactor, when the VFD is energized, you're gon na Get a surprise so don't be pushing in Poland, you have to understand sequence of operation and how your equipment works before you start playing with it. Okay, so let me see what I'm sorry, so why do I jump things out? Well, a lot of my equipment has logic built into it and what I mean by logic, it has some sort of logic, module that indicates trouble problems like, let's just say, a carrier Weathermaker unit. Okay, it'll have a compressor, lockout board and the compressor lockout board will shut the unit down and it you can check power at a certain terminal to find out if it's a low-pressure fault or a high-pressure fault or different things like that. If you turn power off to it, you reset it and there's no safety stored in a board or anything like that.

Okay, that's an older carrier unit. So sometimes by powering things down, you can inadvertently fix the problem or at least solve the symptom, and then you have a hard time figuring out what the problem was so like. I was just talking to one of my service techs, who was working over the weekend. I said I want you cuz, he said.

I think this is bad. I think this motors going bad and I said I want you to prove it to me, okay, and what I mean by prove it is. I want you to physically get in there test the motor make it do whatever it was doing before they called you make it happen again. Okay, actually wasn't a motor.
It was a contactor that had failed. I think yeah it was a contactor, so you know when he called me and said: I think it has a bad contactor and but he didn't see it do whatever it was doing. I said, prove it. So, that's why I don't like to reset things whenever I walk up to a piece of equipment, don't start turning, don't start, pushing, observe, diagnose, get your meter out start checking things talk to the manager.

Ask him what was going on! Ask him the symptoms. Try to get it to do whatever it was doing again in front of you before you start resetting and twisting and pushing and pulling okay, because you can inadvertently fix the symptom which can make it a lot harder to find the down the line. Now there comes a point at which okay, it's time to go ahead and reset this and just wait and see what happens. But sometimes you can go in there and you know figure it out.

So, that's why I tend to jump things out and do this and do that yeah. It can be a problem if I'm working on a big package unit and I jump out the thermostat yeah, there can be some chattering and different things like that. But sometimes that's a risk I'm willing to take, because maybe I don't want to turn it off and wait for a time delay. Maybe the system has an energy management system and it's gon na take 20 minutes for the system to kick back in that kind of stuff.

Okay, so you also have to be careful, jumping stuff out, especially when you have EMS or energy management systems or funky logic, controllers and Internet thermostats. This it doesn't happen so much anymore, but in the past, with the older old systems right, you could short things out. If you try jumping things out up at the at the unit, okay, nowadays the systems have some redundancies and there that you can, for the most part, jump stuff out, but you did have to be careful in the past. So alright, let's see what else I'm missing in here.

Does my multimeter read potential difference or actual voltage? Sometimes I say the contacts are close or system is calling when my meter shows 24 volts well, it depends on what I'm checking so sometimes I might, if I'm looking at a contact, and I read voltage across an open contact, okay, I would technically theory I potentially Would read 24 volts across an open contact that tells me that the contact is open? You know, maybe it's not calling, so it really depends on what I'm working on all right. Let's see what else we got in here before I forget - and I know the moderator BOTS gon na post - something about this in here we have got a spore'ln has another one of their webinars this Thursday coming up June 18th. Okay, the webinar is gon na, be on metering devices, specifically distributors coming out of the metering devices and the importance of them. Definitely something you guys want to check out like I've said before I really do enjoy the spore'ln supermarket series webinars now, just because it says supermarket series doesn't mean that a resident air conditioning technician is not going to get something from it.
There's so much information built into these webinars guys - and I can't stress enough - you guys really need to check them out. Okay, I'm going to post a link in the chat right now, but the moderator boss should be posting it too, but definitely register for that. It's this Thursday, 1:00 p.m. Central time June 18th.

So definitely register for that guys. How bad was it working on that roach-infested our 290 unit? That's funny, so I posted something on social media last night, a little clip of working on a roach infested refrigerator. I don't do that very often, because most of my restaurants are usually pretty clean, but every once in a while. We have a weird situation.

So it's not that the restaurant is a nasty-ass restaurant. They just happen to have a rodent problem right now and they're solving it. Okay, so I actually that clip I took about a week ago and I had to ordered the parts and actually went back to go, replace the parts today. So I had to clean that there were still roaches in it by the way, so I had to take it outside clean it out.

It was still infested. I pulled all the parts out. I have a video because it's one of those things that it turned into a whole thing again right. It wasn't as easy as just changing the parts so I'll be making a video on that.

Like I said, I'm not gon na reveal exactly what happened, but it's interesting and you know just trying to be safe, making sure I don't get that crap all over me, the roach, eggs and stuff. You know it was. It was interesting but stay tuned, that video won't be come in, probably not this week, because I've got some parts coming out, but we'll have it coming out soon and I'll definitely make sure I make a good social media push on that one. Can I explain why a cylinder will burn out if not properly seated on the stem will Calvin? I don't know if I can give you the scientific reason, but basically the coil inside the solenoid coil is creating a giant magnet okay and it'll overheat.

So that's what's happening, the stem actually is the opposite pole. I guess you can say of the magnet. I don't know if I quite said that correctly, but so, if you're ever working on a silhouette valve and you have to pull the cylinder coil off, what I'd highly suggest you do is: stick your nut driver, a metal nut driver in the coil itself, while it's Energized, if you have to do that, and that metal nut driver will help to make sure that coil does not overheat. But yes, it will overheat and burn out.
If you do not have it tightly pushed down on the stem, but it basically just overheats and then it burns out the coil inside of it. So let's see what else do I have experience with Copeland scroll unloaders for 10a air conditioning compressors operation Jeffery? I do not, unfortunately, okay unloaders, essentially just well it's it's hard to say on a scroll compressor on a scroll compressor. It's just gon na vary the capacity of the compressor, but on an old semi-hermetic it basically was shut down, some of the valves or the Pistons or whatever you know, and basically make it only operate on so many, but no, I do not have experience. I cannot really give you any tips on it, so I'm sorry about that, but is there any more? Is there more money in residential or commercial service? That's a great question.

It really depends on what kind of that, what sector of the industry you're going into and I'm actually gon na segue this into another one of the questions I have on my list of things to talk about. Okay, so let me find the one and it's right here so this question right here: I'm gon na answer a couple. Questions and kind of lump these in together, so Edie had sent me an email and he's an older gentleman he's 49 years old and he's getting into HVAC our he's currently going to school, and he just wanted to know if I had any tips, because he realizes That he's an older technician and he wants to know what part of the industry to get into if he's gon na have problems getting hired on as a 49 year old man and that kind of stuff, yeah and you are gon na - have some issues. But it's okay, you're gon na be able to find work.

Okay, but you just have to understand something and I'm gon na segue. This into the other question, there's a whole bunch of different sectors of our industry. Okay, you can break it down to residential commercial, heavy industrial, okay, but then in those you can go in a bunch of different ways. You got supermarket refrigeration, which is arguably in between industrial and commercial.

You know you have process refrigeration, you have facility air, conditioning and refrigeration. You have you know, there's so many different sectors. Okay, so as an older gentleman, it's gon na be harder for you to get into the restaurant refrigeration like I do, I'm not saying you can't, but I'm just saying: you're gon na have some hurdles. Okay, because I have to work in tiny little cramped spaces.

I have to get my fat ass up in attics and climb through things. Sometimes you know I'm up on hot roofs, I'm down in a walk-in where it's really cold. It's slippery surfaces, that kind of stuff, okay, but guess what it's? Okay, though, because if this, if the restaurant refrigeration isn't for you, which there's very good money in the restaurant refrigeration, then you can get into kind of like institutional work, you can go work for a school district, see that would be a great job for you. You can start as a PM tech for a School District right where you work 9:00 to 5:00.
You know and and that's it you know no overtime. None of that stuff. You can go work for a hospital doing the same thing. You know just doing that kind of work.

So, yes, it is a little difficult for an older person to get into the trade, even a heavy person. It can be difficult for you to get into the trade, but there's work for you to do. You just have to kind of find the right little niche to get involved in so hospital work, school district work. You know on-site technicians at a big warehouse like there's all kinds of stuff out there: okay, so where's the most money.

Yet it really depends on what you're interested in okay as an installer for a residential company. You can make good money you're gon na have to bust your ass you're gon na be in hot attics. Okay, but you're, probably not gon na, be working 24 hour service calls you're, not gon na be getting overtime, calls in the middle of the night as an installer tech, okay, you're, probably gon na work, a semi-normal schedule. You might have to work a Saturday or Sunday here and there, but I'm sure it's gon na be scheduled.

Okay as a service tech for a residential company, you're, probably gon na start to get some emergency service calls. Okay, you're, not gon na run them like the restaurant, refrigeration or the supermarket guys, but you're gon na get emergency service calls there's good money to be made in residential, but the downside to residential that I see - and it's just my personal preference is you have to Deal with customers using their own money to pay for things you have to talk customers into things. You have to become a Salesman. Okay for the most part, you're, not gon na, be a mechanic working for a residential company that only goes out and fixes things.

Okay, residential companies - again there is some I'm not saying, there's all residential companies of the same, but most residential companies are there to sell new systems. Okay, there's some that do want to do it riot and fix it and do the best for the customer, but unfortunately, on the residential side, there's not a lot of money in fixing equipment and the money to be made in the residential side. A lot of times is on sales, okay, so as a salesman for residential company, you may not even pick up tools, you may just be a closer you're literally, you know, they'll have a guy go out there and introduce himself and you know: hey. Are you interested in buying a new system? Yeah? Okay, I'm gon na get my colleague over here and the closer is gon na come in and he's gon na sell and he's gon na make a fat Commission off of that.

You know so. There's good money in residential the cool thing about residential is is a great stepping stone to get into the rest of the industry. You get a general idea. You're gon na be in a service van they'll hire more new Tech's in a residential environment than the commercial people will hire new techs okay, so you get into the supermarket work.
You're gon na make insane money, but you're gon na work insane hours you get into the industrial work. You're gon na make really good money. You're gon na be using your brain, a lot working on ammonia and different things like that. You know I don't know the hours as much, but I'm sure you have to work your butt off.

You get into the restaurant stuff and you're gon na bust. Your ass okay, you're, not gon na work as much as a resident as a supermarket tech, but um. You know you're gon na be working long hours. I do 24 hour service calls about once a month.

I get an all-night service call. You know - and you know that's probably say, probably bout once every three months I get an all-night service call where I have to be out there till 2:00 in the morning 5:00 in the morning: changing a compressor, okay, so there's different niches within our HVAC, our trade And there's so many different places for someone to go. So you know if you're disabled, if you're there's there's a lot of different avenues for you. Okay, there's there's plenty of work.

You just got to find it in the right place again going off on a crazy, different tangent th. Where can we get my HVAC, our hats, so they are not available yet, but I have someone working on a website right now. I said at the beginning of the stream I've already approved a few edits on the web site where I'd say, probably about halfway through the process. So hopefully soon I will announce it and I will have shirts and hats available on my website.

You guys will be able to purchase them from there so hopefully soon all right. Let me see what else we got going on here. What am I missing? Really really would appreciate it if you guys give the channel a thumbs up. It definitely helps the stream out.

Okay, so alright, and I think I missed a super chat a while back. Thank you very much. I think I saw something come through or maybe a channel supporter. Thank you very much.

Okay. So I had an interesting question and this probably gon na make my buddy Ralph my buddy Ralph and here's probably gon na cringe and be mad at me. I'm joking right he's not, but someone had asked me and let me find it right here. Oh Adam Adam had asked me why they are banning r22 when co2 has global warming, whatever okay, so why are they banning one refrigerant or I'll? Even argue? Why are they banning r22 when 410? A is also bad for the environment? Co2 is bad for the atmosphere.

Whatever, okay guys, I am NOT a genius. This is where the part the Ralphs, probably gon, na jokingly cringe at me. Okay, I am NOT a genius and honestly, I really don't think about that crap too much. Okay, why are they banning r22 yeah? I've heard a few things, but it doesn't that's.
I don't need to know why they're banning r22? Okay, they are it's just I'm here to fix things. Okay, and I come up with solutions to fix things. I can't use our 20 or I can't use 404 anymore in California, on new installations, so I did some research. I found a refrigerant our 448.

A that's actually how I got in contact with my buddy Ralph Ralph is from Honeywell, and I will give him a plug right now and because he is always willing to answer questions and I'm gon na post. It right here here is his email address. If you guys have any questions hit Ralph up, he will definitely help you guys out okay, but I am here to fix things. Okay, I really don't dwell on the the rules and the reasons why? Okay, I'm not there to do that, I'm there to fix it.

I can't use 404 on new installations. I come up with 448, a it's just another refrigerant. I look at the saturation temperatures I charge it. I fix it, it works, I'm good! I don't put too much thought into that.

So I apologize Adam, but I don't have an answer for why they're banning this or why they're, banning that my buddy Ralph, I can guarantee you can answer that question Adam. If you're in here send Ralph an email or maybe Ralph will answered in the chat. But, okay, that's not something that I I have too much crap going on in my head. My head hurts I've got too much information in there with work and all this different stuff that I really don't think too much about.

Why they're banning things or any of that stuff? Okay, I just move on with it. Okay, it's not that big of a deal you know just find another refrigerant and move on all right. Let me see what else we got in here. What did i miss? No coke nose nope all right.

What did I miss? Let's see, go ahead, Ralph answer all right. Dallas fan, yes, Dallas fan is Ralph from Honeywell. All right. Do I work on cobra head taps frozen? What are the challenges on those next two regular taps? Okay, in the past, I used to have a restaurant customer that the cobra head taps - okay, cobra, head taps are really cool, decremental beer taps and the cool thing about them is if they're working properly, they get about a half a quarter of an inch to a Half of an inch of ice on them and it looks like a cobra head spitting the beer out, it's really cool when you have a cobra head tap.

Okay, so I used to have a customer that had the cobra head taps. No, I don't work on them. Okay, but I will tell you in the past I have had systems that work on them. They are very finicky, especially if the systems are not designed right.

Okay, so what you need is you need below freezing temperature in that beer line right because or in the glycol, because you need it to frost up on the tap head. Okay, the concentration on the glycol has to be perfect. If the concentration is not correct, then you're not gon na get the right ice fill on it. Those are the only issues that I really ran into and I would always lean on the beer technician for that.
I would just ask him what temperature does he need? My unit set at I set the temp control for that he mix the glycol and that's how it worked. Okay, so I didn't really put too much thought into what the trick was. I am NOT a beer technician when it comes to the beer lines. So let me see what else I'm missing in here hated everybody! That's in here.

I really appreciate it. There's a whole bunch of people in here. Thank you guys, so very much again, if you guys are just getting in here post questions in here. Okay thoughts on our 454 B from carrier to replace r410a.

It's just another money-making opportunity for me! So it's okay right! If carriers replacing their equipment, all that that mean or changing the refrigerant over to another refrigerant, there's gon na be some new hurdles that we as service technicians, are gon na get paid to figure out. That's the way I look at it guys. I don't really see this as a frustration. Oh, I can't use 404 anymore okay, so I got to sell some new stuff.

Okay, I don't use 404, so I can put 448 a in a 404 unit, but I'm gon na have to make some changes best world best-case scenario: change the condensing unit change the evaporator put a different t, -- xv in there and you're good okay. So there's some challenges you have to run into when you're working with different refrigerants and Ralph, and I have discussed this - you know again, that's how Ralph and I met was. Was me making a video about four or four and he reached out to me through some friends he reached out through a network and said hey but you're doing something. That's not quite right and he educated me on it and he was correct and I wasn't an I wasn't.

The dick he'd came to me and said: hey bud, you're doing something wrong, but he said it in a nice way, wasn't mean a punk about it and I was like oh wow. I am okay cool, you know, and then we learned, but if you're working with 448 a a there's, some new challenges and new hurdles, it runs higher discharge temperatures, so that theoretically means the internals of the compressor are gon na run hotter. So you might have some overheat issues, so if you use them for 48a, you're gon na need to do some sort of a vapor injection or a liquid injection to try to cool the head of the compressor off. Alright, that's actually gon na segue into another question that I have on my list of things to talk about here.

So Jonathan had asked me about troubleshooting, dtc valves, a discharge temperature controlled valve. I'm gon na make it even easier for you guys. Okay, a dtc valve is a discharge temperature, controlled expansion valve this right here is a Copeland DTC valve, and I'm gon na share another secret with you guys this right here, this DTC valve guess what it's just a temperature responsive expansion valve - and I don't know this To be fact, but just by looking at the build of this sport'ln makes this valve. Spoilin has made one of these valves for years, but when Copeland started engineering, their scroll compressors, they started realizing that on the low temp scroll compressors, they were running really high.
Compression ratios and when you run really high compression ratios, you tend to have some overheat issues inside the compressor, so Copeland, instead of using the temperature responsive, expansion valves, thats Portland makes they said hey. Can you guys make us one of these and we're gon na re-engineer? Our compressor to accept this so Copelan put a rotor Lock valve on the side of their compressor, takes liquid refrigerant into this, injects it into the compressor - and this is just an expansion valve. That's all this is but look at the power head. The power head opens and closes the valve at about a hundred and ninety-three degrees.

That's all you need to know. Ok, so what are some troubleshooting techniques? Ok for this valve. This is a DTC valve on a Copeland, scroll compressor. Well, one of the important things you need to understand is this: is an expansion valve? How does an expansion valve work? An expansion valve takes liquid refrigerant and changes.

The state of the refrigerant puts it into the evaporator, or in this case and jex it into the head of the compressor to cool the compressor off. So with that being said for this valve to work correctly, we need to have a solid column of liquid, going to it a hundred percent liquid going to this valve for it to work right, if you don't have liquid refrigerant, if you have vapor going into this Valve it's not gon na work right, just like an expansion valve got an expansion valve right here. I do cutaways of these things. I've shown these a million times.

Ok, I don't have a cutaway, unfortunately, of this dtc valve, but i will work on doing a cutaway of one of those but uh. So just like an expansion valve, you have to have a solid column of liquid going to this valve now in a perfect world. I've never seen this, but in a perfectly designed system. This valve has a sight, glass, a filter, dryer and a shutoff coming to the valve.

So that way you can shut off the refrigerant to it and change the valve. If you ever needed to this valve, is it takes liquid refrigerant, basically coming out of the receiver, the liquid refrigerant goes into this valve. Okay, it might not be out of the receiver, they might be taking the liquid refrigerant before the receiver. That's why you got to install if you can a shutoff valve before this, because if you ever have to troubleshoot this, it could be a problem if you're trying to pump down the receiver - and this is getting its liquid refrigerant from before the receiver.
Okay, so spore or Copeland actually has a service bulletins on this DTC valve. Okay, the service bulletin, I'm gon na post it in here right now. The bulletin is a e4 $ 12.99, r21 okay, but i'm gon na post a link for that thing. Right now in the in the chat - and you guys can click on that and it's a PDF and you can download it and go to the section that says: DTC valve okay and it's gon na explain how that valves works.

Okay, so on the Copeland scroll, low, temp compressors, just so that you know, there's two types of liquid injection you can do. There is a capillary tube style, liquid injection and there is the DTC valve. Okay, the capillary tube style. Liquid injection basically does the same thing.

    Hey with all do respect. You keep calling stand alone condensers "racks". I live in Florida and a refrigeration rack is refrigeration system with multiple compressors servicing multiple evaporators. A Parrellel Rack. What you would find in a grocery store or mega hotel.

    You mention in one of your videos that doesn’t matter where the sight glass goes, before or after the liquid line filter drier. I noticed that when the filter drier gets saturated, the sight glass start bubbling. An extra hint. Though it is a bit harder to charge the unit with the sight glass bubbling. Not being able to clear the sight glass.
