So, ah, it's time to chill out and get ready for a mediocre q, a 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, hello, my viewers, old school right, dr zarkloff, right zarkloff, i think, was his name. I really liked his youtube channel. It was really kind of corny and stuff kind of like mr rogers, but some factual, good information in it.

So it's a bummer. He stopped posting on youtube. There's a lot of the og guys that stopped posting on youtube. But oh well, it's a bummer, hey how you guys doing um, i'm doing pretty good over here uh.

My my shoulder neck back elbow whatever pinched nerve thing is getting a little bit better. So that's cool! Um! Yeah! Do me a favor if you guys haven't already, as you guys are scrolling or coming in here and stuff smash the thumbs up button. It definitely helps the stream. It really does.

Okay, so, as usual got a couple things, i want to talk about. I'm going to check out the chat answer. You guys questions, but let's get this started off right. Okay, my name is chris and if you don't already know, i'm an hvacr service technician.

I know we've got a lot of new viewers right now so um i do. These live streams to kind of consolidate the questions from all the youtube, video uh comments and emails that i get. So i try to kind of look at the commonly asked questions and kind of address them on this live stream, so those that are new in the chat. Do me a favor if you have a question, put your comment or question in caps lock inside the chat and then myself and just keep posting it until i answer it or myself or the moderator tells you to stop connor.

Thank you very much for that. Super chat, but i really do appreciate it: okay, um, if uh yeah, so let's get on with it so um this last week i had some pretty interesting videos. Uh one of them was kind of boring, as you guys saw, i kind of was. I was running out of footage, but then i got a really cool service call too that led to a really cool video that actually led to a lot more okay, so um, but before we get going on that, i just want to kind of do a couple Reminders here, uh sporland has a webinar coming up this thursday it'll be posting in the the moderator bot we'll be posting it in the chat.

Um sporlan's webinar is gon na, be on uh high pressure, oil level controls it'll be uh this thursday, three four i'm gon na post it in the chat myself real, quick, um and uh check it out or uh sign up for it uh it's thursday. I think they do what did i say: 1 p.m. Uh central time is usually when it posts so um. Let's see the next thing.

The hvacr training symposium uh, with hvacr school uh, brian orr, is hosting it it's going to be at his his offices in claremont florida it'll be next thursday through saturday. It's a three-day event. The cool thing, though, is, if you can make it in person, go for it. I think there's still some in-person tickets available, but if you can't make it in person, he also has a live stream kind of a thing right where you can log in online and he's going to have some of the presentations online.

Now i am not going to be there in person this year, but i will be doing a live well. The plan is that i'm going to be doing a live broadcast specifically for the event whether or not i can live stream that broadcast. I don't know i haven't figured out the logistics of all that yet, but at a minimum i will be presenting uh next thursday for hvacrschool.com. If you're interested in signing up for brian's event just simply go to hvacrschool.com uh, i want to address something really quick too.

I'm sure a lot of you guys get this or know this, but maybe some of you don't brian and i are two different people. Okay, if you couldn't tell by the videos brian looks different than me: i look different than brian, but we actually do get mistaken for each other. Quite often people watch my videos and they'll. Send me an email saying: hey, i really love you know this or that and then i'd be like hey.

That was brian. That did that. So we are two separate people uh. It's interesting that we have similar names.

It's just kind of a coincidence that that happened. We started our stuff right around the same time. I picked the the name, hvacr videos and he picked the name hvac school. But if you try to find hvacschool.com, it's not brian, so i'm assuming he had to pick hvacrschool.com, which maybe that's why people get a little confused so but yeah we are two different people, so um all right.

Let's see what we got going on here doesn't sporland know we got jobs, nate, peterson, good point, okay, so uh the cool thing about sporland's stuff yeah. They do do it because what it is is they're engineers and uh the engineers do it on the clock. Basically, during their normal business hours, but it always posts on their youtube channel, go to spoiling video on youtube and you can see all the stuff posted like a couple hours after. It's gone, live okay but um i'll log into it.

Sometimes, when i'm working or something like that, it's just a lot like a telecast. You can listen to it. They do have video stuff, but yeah. It's one of those things.

You can always watch it after the fact. If you need to so um all right, uh, john gorthy, thank you very much man for the nice words. I really appreciate it all right. Let me see what else we got going on in here: um, the stainless, oh yeah, the strobe reflection that that happens.

It's the silly lighting for some reason on the sign and then what you're actually seeing watch this is you're. Seeing the light reflecting off my fan, it'll, probably stop strobing, as the fan turns off. So all right. Let me see what else um.

What am i missing inside the chat? I already answered all that stuff, all right cool um. Let me see what else we got going on in here, so uh the elephant in the room. Why am i using testo products did field piece? Piss me off. Did i decide to get rid of my field piece stuff? No, okay, i'm not going to get rid of my field.

Speed, stuff! It's not going to happen. I love the field piece products. I'm going to continue to use field piece products. The people have been asking me: multiple people have asked me: why am i using testo? Okay, if you don't understand, i'm using testo right now, because i'm reviewing a product all right, that myself and the overtime crew are starting a new youtube channel or where we're continuing.

My my youtube channel called hvac our tools and we're all going to start posting videos on that youtube channel. Okay, we all have the testo products. We ordered that it was sent to everybody all right, but i just want to make it clear um for this video for the testo products, nobody supplied those to us. We did not get them for free, we paid for them, okay, those were all paid for and we're going to give an honest, unbiased review on the testo products.

I myself was surprised by a few things that the testo products had, but i was also disappointed in a few things that the testo products had we're not going to be on this youtube channel. We're not going to be bashing anything, but we are going to be given our opinion and letting you guys form your own opinions. You know from those okay we're just going to be given the facts and all that stuff ike. Thank you very much for that.

Uh super chat, but i really appreciate it. Yes, we do have a discord server. There should be a link to the discord server posting in the chat by the moderator bot here in a few minutes. It's auto post it'll come up here so, and i already got the coke nose going strong right now, so um all right, uh, oh! So as far as the youtube channel hvacr tools um, let me get a link to that right now.

I happen to have it right here last week, when i mentioned something in the video about it. A lot of people were saying that the uh here's a link for the tool channel right now so please go subscribe, give it some views, give it some watch time because that's going to help us to get to the point of monetization, which will help us to Fund the tool purchases that we're going to have to make, because this is a interesting project of us - you know having to do this, so that's a whole nother thing um. Okay, the last week we had two videos all right, um on these two videos. Uh.

Let's see the first one was the walking. Cooler is hissing, okay and the second one was the late night. Walk and freezer service call all right. So we're going to go through through some questions on those two videos and then we're also going to get some other stuff and we're going to address some questions in the chat too.

All right, let me get to the chat and see what i'm missing here. How common is it for people to steal, copper lines where i am um, i mean it hasn't happened in a while, but that particular location where the incident happened. I'd say it happens. At least once every two years, or so they have something stolen.

I think i mentioned it in the video, but they actually had an entire two-door reach and cooler stolen off their back dock. One time that was in a pallet behind a cage. They cut the cage, open and yanked out the giant region cooler. I don't even know how they transported that thing.

It was huge um. Can i give one bad thing and one good thing about the testo products right now: hmm uh a hard one. That's that's a really hard one um. I can't really spill anything yet you got ta wait for the video because there's some interesting things about the testo stuff.

Okay, so for reference we are reviewing the new testo manifold, the 550s, which is the new manifold with a new screen. It has a wireless vacuum sensor. Well, at least you can buy a package with the wireless vacuum sensor. We also are reviewing the new testo 550i, which is the manifold without the screen.

Um interesting how they work and really interesting about the manifold and the the one without the the screen is that they both operate differently within the app and the 550i has features that the 550s does not have. So i found that very interesting. There's things within the app that you can do with the 550s that you can't do, i'm sorry that you can do with the 550i the one without the screen that you can't do with the 550s. That has the screen, which kind of baffled me.

So, that's about all that i'm going to talk about the testo products, but trust me. The videos will be coming out on the hvacr tools. Youtube channel and it'll all make sense. Okay, philip! Thank you.

So very much for that super chat holy. That's an awesome. Super chat man. Thank you bud.

I really really appreciate it. Okay, all right um and no. This video is not. This video is not brought to you by value testers.

No, it's not brought to you by value testers, okay, all right, um! Let me see what else we got in here. Huh. Have i ever seen refrigerant blow out of compressor terminals? No, i have not uh. What do i think of heatcraft's new low-profile coils john deere fan? I've worked with a few of them, they can be frustrating at times i mean the low profile.

Coils have always been kind of frustrating. I'm assuming that you're talking about the slim line, the ceiling mounted slimline ones um. If you're talking about the standard, uh ceiling mounted, you know ones that are about that tall uh. I don't know they're they're, all right, nothing, crazy to talk about them.

They have a couple different models, they have the intelligent, they have the standard model and they have the um qrc, which is the old model, but all right, i'm going to get to my list of things to talk about so uh. Oh, i did want to cover something else. I'm kind of a really bipolar live stream today, i'm like all over the place, can't can't focus on one thing, so i did want to cover something. So you know i kind of already talked about it with the uh.

The testo products - i am using testo products right now because it's for a review that i'm doing for the tool channel, but i do want to make it known that i'm not owned by one brand. Okay, you see me using field piece. A lot i'm not owned by field piece: okay, i'm free to do anything and use anything. Even when i do partner like i'm, not currently partnered with field peace on anything right now, i'm not saying something won't happen in the future, but same thing with spoiling.

I am partnered with spoiling right now, but everybody understands when they work with me: i'm not committed to using only their products period. Okay, no matter who i work with that's part of the deal. If i ever make a deal with anybody, is i'm never going to be owned by anyone? I'm always going to be able to make my opinions known. If i like something i like it, and if i don't, i don't, but i'm never specific to one brand.

Okay. So, just because i use field piece, a lot does not mean that the first time i use testo i've thrown field piece out the door, no, not at all. Okay. I still continue to use field piece um, but maybe there'll be some testo products brought in that.

I might like so who knows: okay or some new brand. That comes out. I mean i'm all about what works and what's functional really so, and what works for me all right and that's something important to understand too. Just because something works for me doesn't necessarily mean it's gon na work for you and vice versa, right um, you know it's really about what you're comfortable with and what works good.

You know some people hate field, piece products. Okay, i prefer them. It just depends. So i mean it's all about what you like.

That's all all right, um, i see uh jason farmer, you said leak, stop questions from a few weeks ago. I don't know what the context is about that, but i am going to say that i don't like leak. Stop i don't use leak, stop it's not something that i use, even in a last ditch effort. I have used it in the past because customers basically demanded it, but trust me i'm going to give so many.

So many disclaimers, if a customer wants me to use any type of a leak sealer in a system. I do not like them. I do not endorse any of them good for you, if you like them, but i just don't okay, so league stop is not a solution for me period, i'm a fan of using what came in the system with which is oil and refrigerant. I personally don't like adding very many additives at all.

I have used additives in the past, such as dye and different things like that, but i can count the instances on my hands and every instance that i have used dye. I have regretted, okay after the fact, because that stuff just comes back to haunt you, even if you change the compressor that had dye in it, you're still going to have dye in the system and it sprays all over you and it just pisses. You off same thing with any of these additives that they say: unstick, txvs and different things like that. I've never had success from any additives that i've added into the system, whether it be to stop acid formation or anything like that.

Now, i'm not going to say that i've had failures because of any additives, because i've honestly other than being pissed off with a uv dye. Uh i've, never a system that i put leak stop into right, because the customer asked me to i've never had a problem. Specifically, because of the leak stop just for me personally and never stop the leak. Okay same thing with these additives that um that supposedly make your system operate more efficiently or unstick, txvs or whatever.

I've never had anything bad happen from them, but i've never had anything noticeably good happen from them. So you know i'm just not a fan of using them. That's all! Okay! No offense! If anybody is it's all good, i'm not saying that you're wrong. If you use any of those at all - okay, it's just my preference not to so all right um, let's see as far as in reference to the walk-in cooler as hissing video mike had asked me.

Why didn't just bust out the leak detector and he was curious? How much my quote was to repair and why they replaced the equipment now to i was kind of paraphrasing mike's question mike was saying hey. He was kind of being a little like uh aggro about it. Saying hey, you know what you know you you could have just gotten the leak detector out. Why did you have to change the whole system? Okay, look at this here's the deal when it came to that video um.

I was on overtime and i didn't want to spend any more time than i had to do. Okay, so i'm going to answer another question in the midst of this. As i'm talking when i went up on that system, i can remember that was all the way back at the end of summer. When i went up on that system, it was an overtime service call.

The customer called me. I went out there. It was clearly low on gas, okay, the sight glass was empty, the pressures reflected low, and so i added a little bit of refrigerant, but what people don't see a lot of times? You know the next question that i had is. Why did i add gas before i looked for a leak? Okay, i get that a lot too when i first get there.

The first thing that i do is i'll walk into the box and kind of use. My senses look around. I noticed that the uh you know i didn't smell anything funny in the in the box um, you know so i just kind of used my senses. I listened, i didn't hear any big hissing leaking sound or anything went up on the roof added a little bit of refrigerant and had the system been completely flat on gas, of course, i would have gone and you know put a little gas in there and done A leak search, but being that it was only a couple pounds short.

I went ahead and topped off the charge i went downstairs and it didn't really show it on the video, but i did do a leak test. Okay, just a quick one, though just downstairs at the evaporator and then i didn't see anything jumping out at me. It wasn't pissing out. I thought it could make it through the weekend we got through the weekend now.

You didn't see it on that video, but i actually sent another service tech out there a couple days later, he did a leak check couldn't find anything flash forward to this month or last month. So it's been quite a few months since then, it hadn't leaked out since and the customer had decided they want to go ahead and replace the equipment. Now that particular customer that i work for they buy their own equipment. So i had no control on that and i'm going to go into a lot of questions right now, because a lot of people ask me questions about.

You know what happens when. Why do i do work for customers that purchase their own equipment? Well, here's the deal as a business owner every business owner out there has to make a decision. Okay. What kind of work you want to do? Do you want to do home warranty work? Do you want to do warranty work for commercial refrigeration? Do you want to do la di da di da? Do you want to do a new install for gcs? Do you want to do all this different stuff and there's good and bad things? You have to weigh out the good and the bad at every single situation and every single job you choose to do so.

I deal with commercial restaurants. That's what i do all the time. So do i want to stay busy during the slow time. Of course, i do okay, we're in the midst of this crazy pandemic thing and restaurants are dead, and i'm so thankful so thankful that i work for some of these chain.

Restaurants, that are really really big, because i'm thankful that they're surviving this yes they've had to cut corners. Yes, they've had to cut back on a lot of different things, but they're still feeding me work. Okay, so i've had a lot of installs. Lately, i've probably done in the last three weeks: i've probably done two or three walk-in installations where i've changed, evaporators and condensers run new line sets.

And yes, it's all been customer provided equipment, but it's worked for me, okay, so i'm thankful for anything. I can get right now. The restaurant industry here in southern california right now is completely dead. We are, we have not been open to in-person dining since, like may of last of of last year, okay, we had like a brief like two week period where they opened up the restaurants and then our our numbers went up and they closed everything down.

So our restaurants have not had very many sales they've only been allowed to sell to to go and pick up, orders and stuff like that. So i'm thankful for anything that i can get. So it's just a business decision that i make to go ahead and accept that work from those customers. Okay, yeah.

It does kind of suck that i'm not getting to mark up the equipment and sell that to them. But hey you know what, in these crazy times, right now i'll take what i can get okay and i'm thankful for that so um! You know. A lot of questions came in too hey when the restaurant provides their own equipment. What happens if they provide the wrong equipment? What happens if it's sized incorrectly? Well, it's on them? Okay, i'm not signing off on any of this equipment all right, but i will tell you that knowing me, if you guys, have watched my videos enough, i still do my due diligence and contact the company.

That's supplying the equipment. Ask them to send me. You know the load calcs ask them to send me the tonnage of the equipment. Then i typically do my own load calculation just to verify, but it wouldn't be on me if the equipment was installed incorrectly.

It would just be my problem to fix, but of course i would charge for that, but still just to eliminate the headache and give my customer the extra satisfaction or whatever i still verify and confirm that the equipment is sized appropriately. Okay, i also want to cover something else, and this is another couple questions that are inside the chat uh in the comments on youtube too. You know, i am not perfect guys and i hope that i get that across to you guys that i'm not the best installation guy. I make mistakes, i'm human just like every one of you guys.

Yes, there is a few guys on instagram that do you know amazing installations, and it's like every installation is by the book. The piping is pitched correctly there's you know p-traps in every place, they're supposed to be in they're, reducing the size of the pipe on the risers. You know they're. Oh my gosh, it's amazing.

It's strapped every six feet and perfect. I i could only wish to be as good as those companies okay, but i'm not perfect. Okay, sometimes jobs don't allow for me to be perfect. I have to do what i have to do.

I have to get the equipment going all right, so i don't always pitch my pipe correctly. I that was a comment that came through and it's okay, i'm not mad at any of these comments by the way guys, i love the feedback from all of you guys, if any of you guys see something that you think i'm doing incorrect in my videos. I appreciate the feedback. Please send me an email, okay.

What i do ask is that you're, not a punk in the comments and just blasting me, i mean i'm okay with criticism, but there's there's decency too. Okay, i don't care if people criticize me in the youtube comments either and i'll, make it clear. I think i've said this many times too. The only comments i ever delete in youtube is: if someone is bashing just clearly bashing someone else or if people try to guess restaurant names correct or incorrect.

Those comments are automatically deleted. Okay, um. I don't delete comments. When people talk crap about me, it's fine.

Everybody has their opinion and i'm not one to go in and ditch all that stuff. I'm not a social media sensor like some of these crazy social media companies are doing right now. You guys are free to say what you want, but i just ask that you have some respect, but i mean whatever you know but send me an email. Let me know if you can help me to improve, because i would love to become a better service technician.

I'd love to do things better. Okay, so i answered like five six questions there and now i'm at a loss as to where i'm doing i already covered that one. I already answered that um answered that one uh, okay, so on the overtime service, call on the walking coolers hissing. How come i didn't finish, the call how come i did a partial repair.

How come i didn't do the leak check when i was there um? Well, because number one um the customer only wants me to do. You know the least amount of work possible to get them operational while i'm on overtime. Okay, now there's times that you know it's in the middle of the summer - and i don't have time to come back, so i'm going to give them everything they're going to get. But i really didn't want to be there that night, so i gassed it up made sure it wasn't pissing gas out and i bounced and we came back a couple days later and we finished the job.

Okay, so yeah the customer had to pay me to travel back out and, yes, i did charge them a travel charge and you know my hourly driving back out there. Yes, i did okay, but that's just how it works. Okay, all right um, i'm gon na get to the chat and see if i'm missing anything in here did i leak check the unit with the copper missing. No, i'm going to get to that one here in just a minute, so uh has spray foam ever tripped.

My h10 in a box and or roof penetrations cameron, so with my new leak, detectors um the newer ones. I noticed that i don't really have the issue with the spray foam and different stuff, like that. I used to see that quite often with older leak detectors. I don't know if it's, maybe they change the polyurethane foam.

Maybe it has something different in it, but um. I don't really trip up leak detectors anymore. Now i don't use an h10 leak. Detector.

I've never used one before nothing against them. A lot of people swear by them. The leak detector that i'm currently using right now is the d good gosh. The name is too too long.

The inficon detex stratus there's it's. It's got three names, this leak detector and i think that's silly um before that was the detex select. The amphicon detex select was the one before that uh. Both of those leak detectors are amazing, so the inficon i'm gon na call it the stratus.

Now the stratus uh is the next step up. It's the big brother to the uh detex select um, but i really don't get tripped up by foam and stuff like that too much anymore. But that was something that i did have to worry about in the past. So, let's see what else we got going on here, uh philip! Thank you.

So much for the nice comment bud. Do i ever work on water chillers? No um! I don't! I don't work on chillers in general, i did used to work on some water-cooled equipment when i used to do a bunch of hospital work. Their walk-in coolers were all water cooled and then they had water source, heat pumps all over the place, and then water cooled air conditioning units in the server rooms and stuff, like that, i used to do a lot of that work, but i've never worked on chillers. In general um all right, let me get what else in here.

Uh yeah, please smash the like button guys we have 358 people watching and 155 likes so smash that help the algorithm. Please the algorithm. I guess i should say so all right um. Let me get to this.

Let me get to that: um, okay, let's get to the late night, walk and freezer call, which i know a lot of people that one's fresh on everybody's minds. So i got a service call. The customer actually called us on the phone before they dispatched the work order and they said hey all. The copper was just stolen off of our walk-in cooler, our walk-in freezer, and they sent us some pictures.

So i was able to look at the pictures and pick up the materials that i thought i was going to need on the way to the job site, so that was really nice. I appreciate the customer and i told them thank you for sending me those pictures. So when i got to the job sure enough, the copper was missing, some tweakers had gone up there and stolen it all right, uh it's in a crappy area. That's in san bernardino, um, not the greatest area uh! You know it's got a lot of restaurants and stuff in that area, but it's not the greatest location.

They got a lot of tweakers, a lot of homeless people and someone just got up there and they were hard up for cash and they stole 20 worth of copper and cost the customer thousands of dollars worth of damage um. So i'm going to give you guys a little teaser all right. They didn't just stop at the walk-in units. All right! That's all i'm gon na say there'll be another video coming all right.

That's that's all! I'm gon na say about that. All right! It didn't just stop at the walk-in units and it went a lot further a lot further, so it was pretty crazy um. I went back there today and uh, so we went back there today and we finished up the repair on the walk-in freezer. Okay, because i got them going, i went back the next day and then i came back today with all the clamps and all the other materials and we cleaned up the line set, and we also did the repair that i showed on the walk-in cooler where we Changed that service valve that they started to cut off.

We we took care of that today too, and uh yeah. It went a lot further than that, so stay tuned for that video all right, um with that service call, knowing that i was going to that location. Knowing that tweakers had just stolen all the copper, what did i do to protect myself when i was going to that service call? Did i bring a gun with me? Okay, um, i'm gon na be honest with you. I thought about it, but i did not um.

It was simply because i was lazy uh. My gun is locked away in my safe and i thought about grabbing it and taking it with me, but i just didn't need it. I figured i'd, be okay, all right. So um i felt comfortable enough, you know, had i gotten there and it looked really shady or something then yeah now i probably would have done something, but i felt comfortable enough.

So no, i did not bring a gun with me, um all right. So the next question: why do i not build a care? Why does the customer not build a cage around that unit and electrify it? That sounds like a great idea. I think that would be awesome if we could electrify our cages. So that way, if a thief goes up and tries to seal it, they get electrocuted and they fall over dead on the ground, shaking convulsing, whatever.

Of course, i don't wish death on anybody, but it'd be cool to see someone laying on the ground convulsing for five minutes then get up and get arrested, um, but i live in california and that ain't happening. Okay, you are not allowed to electrify a cage um guys. I can't even shoot someone that breaks into my home without being in trouble for it, so no not in california, all right um. As far as the customer goes what's the process with the customer.

Okay, what do they have to do now? That was a question that i got quite often you know what that's out of sight out of mind. I have learned to not get involved in that kind of stuff when they have theft, we don't i don't get involved. You know okay, so let me give you from past experience. What happens if uh i walk up to a job and i find out that another contractor was there and um the other contractor damaged the equipment.

I don't get involved in that crap, okay, because as a business owner, it turns into a headache. Okay, so plain, and simply i don't get involved in the politics i walk up to the customer. I say: oh no, the copper is missing, don't know what happened. I give them a quote or i do the repair and i give them the bill and i move on okay.

In my experience, when you start bringing stuff up to the customer, hey man, you need to go through your insurance or hey. You need to go after the other contractor guess what happens? I typically don't get paid until the other party pays the customer, so i prefer not even to get involved in the politics. What happens next? I have no idea, i just hand them my bill. Hope they pay it on time and move on how often i already answered this one.

But how often is this happening here where customers are still or where you know thieves are coming in and breaking into copper? I already said it uh once every two years at that location they have something going on. It doesn't happen very often um now, what's interesting is very recently. We used to have a huge problem with copper theft. When the copper prices went sky high, our local government got involved and started, requiring all the scrap yards to really scrutinize the people that were bringing in scrap copper and they had all kinds of rules and uh.

What actually used to happen, then, was you would go to trade in some copper because i usually keep copper. I have a big barrel of it and i take it in you know once or twice a year and uh i'll take in a big barrel of copper and then they would say: okay, we're gon na have to send you a check in the mail or you Can come back in two days and get your money uh? They don't do that anymore. It actually blew my mind. It'd been a while since i've taken, copper - and i just took some in probably about two months ago - and they gave me cash on the spot.

I wasn't wearing a work uniform, there's another caveat too: if you're a contractor they'll give you the money right away, if you show them a contractor's license, but i didn't have any of that stuff with me. I just went in and they gave me the money right away. So that kind of leads me to believe that the scrap yards are not being is meticulous with that anymore. And it's probably going to lead to more copper theft.

Because if they're not really scrutinizing the tweakers that are bringing the copper in, then maybe it's going to continue to happen um. So let me see uh, oh, and i wanted to bring up the point too that, like you know, even at my my own house, my trash day is on monday and i have to freaking scream at the damn guy that goes through my trash. Can all the time, because there's a guy that comes in and takes all the plastic out of my trash can and i always go out there and try to kick his ass get out of my trash can get out of here. You know he stopped coming to my house because he knows i'll go out there and scream at him.

Tell him to get out of my trash. I don't need him in there. So as far as a technical question goes, so jason had asked me about 448a refrigerant. So here in california, we've been using 448a or at least i have for a little over a year and a half now um.

So as the new um, you know, mandates go across the united states and you know the refrigerant regulations and all this different stuff. A lot of people are having to get introduced into 448a 449, whatever one you choose, and a lot of people are afraid of the refrigerants okay, because it has a high glide, there's a lot of like technical terms about these refrigerants. That scares people. Oh my gosh.

It's a high glide, refrigerant you're, going to have all these problems and it's just another flavor refrigerant guys, there's nothing wrong with 448a 449. Whatever you choose to use okay, you don't need to be concerned with all that stuff. Yes, there's things you need to kind of think about like okay, how does it affect performance and stuff like that and there's sizing restrictions and stuff? But just do your research, it's nothing to be afraid of it's nothing to be fearful of 448a. It's no big deal just make sure that your components are sized appropriately now when it comes to retrofitting systems existing systems to 448a or whatever.

You need to do your due diligence - okay, especially if you're retrofitting and changing the oil in the system for like mineral oil to a polyester oil there's going to be some issues there, chris miller. Thank you very much for that super chat man. I really really appreciate it. Um chris miller send me an email to hvacr videos, gmail.com, and i can give you some more feedback on your question: okay, bud, um, so you're replacing uh with the heat pump.

My thoughts, uh yeah, send me an email. We can talk a little bit more about it, but um, so i lost my oh with 448a um. You know there's really not too much to be afraid of, but when you're doing retrofits on existing refrigeration equipment and changing over to 448a, there are some things you really need to consider. Now.

Manufacturers will tell you that you know you can get away with using the same components: expansion valves, distributors or nozzles in your distributors and stuff like that, and you can okay oftentimes. If, if your expansion valve before was sized, you know appropriately, when you change over to 448a, you may be able to make adjustments to the valve and it may work properly. But your best bet, when you're doing a conversion to 448a from an existing system is to go ahead. Do the calculations pull the nozzle out in between the expansion valve and the distributor put the correct nozzle in there if it needs to be changed and size? Your expansion valve appropriately, okay, you do need to use a power head, that's basically made for r22.

That's that's pretty much because the pressure pressure temperature relationship is pretty close to r22, so they're, actually using r22 medium temperature power, heads for 448 and 449. same as 407c and your valve may need to be adjusted appropriately. Okay, so keep that in mind, but it's nothing to be afraid of um. It works the same.

It's just another flavor of refrigerant. Don't worry about pressures, okay, when it comes to any flavor, stop focusing on pressures and start looking at temperatures. If you, if you know you have a baseline on how your walking equipment is supposed to operate just be concerned with temperatures, do you want to run a 10 degree td on the evaporator? Do you want to maintain 35 degrees in the box if you're running a 10 degree td, then your saturation temperature should be about 25 degrees. Don't worry about a pressure? Okay, just look at the temperatures same thing on the roof when it comes to your condensing temp.

Okay, that's why it's so important when you're starting up equipment, new installs and things that you write down all the information. What's your condenser td, what's your evaporator td that way someone has a baseline to look at from in the future. Okay! So keep that in mind! It really does help you when you're dealing with some of these new refrigerants um. Let's see oh good question so uh in the video where i was there at night time.

Of course - and you know the copper was all stolen. Of course, you know we had some issues and um it was. It was late and you know you guys saw where i went to go start it up and there was no low pressure control because the capillary had broken off. That kind of stuff happens just take it one step at a time, but why, when i charge the system, did i dump all the gas into the receiver? So what i did was i front seated the king valve on the receiver and when you front seat the king valve the service port on there is open to the receiver, but not to the rest of the system.

So i like to dump as much gas into the receiver first so that way i can control the flow, because i always try to hot charge into the high side first. But if i can, i prefer not to load the whole system high and low, with refrigerant. Just sitting there i prefer to dump it into the receiver just to modulate the startup and not flood the compressor with refrigerant coming back. Okay, so usually what i do is i go ahead and open up the receiver.

Let it meter, through the expansion valve and flow through the system, naturally versus just dumping tons of refrigerant in there and having the system equalize out just a personal preference of mine. Just that way it helps on startup, so um. Let me get to the chat. What am i missing? Uh any co2 coolers? Yet no, i don't work on anything.

That's co2! I've seen a few like soda, coolers and stuff like that, but i haven't worked on anything so neil h, your question was next on my list. Neil h asked me a question about what tool am i using to cut open compressors, so i've done a couple videos where i've done autopsies on compressors pulled the heads off of them to figure out what's going on inside of them? Typically, what i will use is a grinder okay, and what i will do is score very slowly: the outside shell of the compressor, nice and slow, really controlling the grinder. So that way, it doesn't go through and damage the inside of the compressor, and also that way it doesn't shoot the crap all inside the compressor and get stuck in the oil sump, because when you're doing the autopsies on the compressor, you know it's nice to know. When you open them up, if there's metal all in the oil, then it helps you to understand hey.

Maybe there was a a mechanical failure, something happened, but was that? Because you were just cutting it open with a grinder and shooting all the crap inside the compressor. So it's just a slow process. I just use a grinder and go nice and slow all the way around, just slowly scoring the edge until it's almost about ready to break and then just just hit it very lightly. So it just takes time.

So just a grinder and lots of time is what i use to cut them. Open. I've done a lot of compressors and once you've done a few of them, you start to learn where to cut them and where you're, safe and where you won't damage things and how the compressors are assembled. So you get a little bit more comfortable with it.

The first time you ever open up a compressor you're just going to butcher everything just just accept the fact that you're just going to tear the whole thing up and then from that point forward, you'll start learning, hey, i shouldn't have cut there and that kind of Stuff, i encourage everybody out there to cut components open whenever you can. It helps you to understand everything if you guys, you guys have probably seen most of this stuff, but i like to cut all kinds of components open. This is a head pressure and lac valve that i took a band, saw to and just cut right down. I disassembled it because it's got mechanical components, disassembled it and cut it in half.

I actually went through like three of these valves before i got it perfect and then uh put it back together. So that way i could show my text hey. This is how a head pressure control valve works, an lac valve, and i got the same thing here with an expansion valve too, is i just disassembled a flare expansion valve right here and cut it open and then reassembled the pieces. So that way, you can see the mechanical action of the expansion valve and how it works.

So this kind of stuff really helps anybody. It doesn't have to be new, like these happen, to be new parts that i had in the shop that were just sitting there, but it doesn't have to be new parts. You can cut up old parts, there's nothing wrong with that anything. You guys can do to learn better, go for it, cut open, compressors, cut, open expansion, valves, cut, open dryers, get a dryer right here.

This is one that i cut open, just very slowly with a grinder, so you can see the desiccant material inside of it. You know i love doing that kind of stuff because it helps us to better understand how stuff works and how a dryer is assembled. You know look at the mesh screen, that's in a dryer, you know, there's there's a piece of fabric mesh and then there's a screen behind it. You know there's so much cool stuff about that.

So i encourage everybody out there just start cutting components open, that's something! We can all do to learn better educate yourselves. It makes yourself more valuable for sure, okay um, let me see what else we got going on in the chat in here. Does the tightness test on the s-mans allow you to see it on the measure quick app? No, the measure quick app does not have a tightness test as of yet but i'm sure, if you send jim bergman an email, maybe he already has that on his list. I know he has a lot of things that he's working on, but maybe that's something he can do the tightness test.

If you're wondering is a pressure test that uses suction line temperature to compensate for the the pressure change, that'll happen with nitrogen, so um. If you don't already know, there's a common misconception, that nitrogen is a gas okay, which it is but there's a misconception that nitrogen is a gas that never changes pressure. That is absolutely incorrect. The simple fact that it's a gas tells you that it changes pressure as it changes state.

Okay, um a gas is gon na change. The the you know, there's no way that it doesn't change pressure, so everybody calls it an inert gas and all this stuff. Now i will say nitrogen has very small pressure changes, but it does change pressure: okay, based off of temperature, so this uh, the the tightness test, basically takes the suction line temperature and it compares it and gives you uh it. It helps you to understand if your gas pressures change, like let's say, you're, doing a pressure test and you come in the afternoon and you pressurize it to something - and you come back the next morning and your pressure is low.

Well, it's cold outside your suction line's colder. The pressure of the nitrogen is going to go down as it gets colder outside okay. So it's not necessarily just because there's a leak. Okay, so uh lots of manifolds, even the new testo app well the testo manifold.

I think was one of the first that did a tightness test, but um but yeah. I don't think measure quick or actually i know measure quick doesn't do it yet, but maybe since in measure quick and email and ask them about it, i'm sure they'll. Do it. Um, let's see what else we got going on in here.

Let me see why is 440 tagged on my video number 440 tagged on my video. I don't know what it where is number 440 tagged. I don't know what that means. Number 440, no idea yeah! I don't i don't know uh why or do i work on semi-hermetic compressors, often not as often as i used to it's it's pretty um rare that i come across semi-hermetics anymore and the small stuff so uh yeah uh, kevin pfeiffer uh did i have the shits On friday uh, i don't think i had the shits.

Maybe i don't know it doesn't surprise me, i mean it happens all the time so uh, let's see what else number 440 is the amount of likes for chris to say chingus all right. Let me see what else we got in here: um you're, a welder and you're looking to get into hvac any advice, uh find a good place that will hire you as an apprentice. Okay, then get involved in some sort of an educational program, whether it be private or public. I tend to prefer to push the public stuff just because i don't want to see someone spend a crap ton of money on a private education and decide that they don't want to do the trade.

But what i would encourage people to do is go get enrolled in a public community college, take one or two classes. If it's something you think you're going to like you know great. If it's something you don't you're only out a couple hundred bucks right or if you're gon na go to a private college, make sure that there's some sort of a policy that you can get your money back. If you don't continue the program, i just hate for someone to go, spend 18 grand or whatever it is for a private college and then not go through with the program.

So be cautious about that. I'm not saying that private schools aren't good because i'm sure they will um. When do i replace vans in the fleet, we like to see about 150 to 200 000 miles out of a vehicle before we start considering replacement after about 200 000 miles. When you have multiple vehicles, they become a liability and there's nothing worse than needing a technician to show up on a job site because he's scheduled somewhere and his van breaks down.

So we use the chevy express vans and we find that at the 200 000 mile mark is when we really start to think about replacing that van and start considering replacement options. So for us, it's pretty uh the way that we ride the vehicles and maintain them. It's pretty safe to say that you start to see transmission problems within 150 000 to 200 miles thousand miles, and you start to see engine failures within 200 to 300 000 miles is when we start having to see that and we take care of our vans. We run synthetic oil, we do oil changes every 10 000 miles with the synthetic we we keep them up to date, but just you know they get worn, hard basic or ridden hard kind of all right.

Um, let's see what else we got in here uh. Can i have a trailer with my company name on it filled with condenser fan motors uh? I actually have a trailer with my company name on it, but no not filled with condenser fan motors um. Let me see what else can i explain p-traps on the evaporators for walk-ins when to use them when not to use them anytime, the evaporator is below the condenser it's safe bet. I put a p-trap on the system now: there's piping practices, proper piping practices, ppp yeah, proper piping practices.

There you go that uh say that any rise above i don't know 20 feet 15 feet or something like that. You should do a p-trap, but the concept of a p-trap is if the oil ever gets out of the compressor and makes it downstairs to the evaporator. It's damn near impossible to get that oil back up. If you don't have the pipe or the refrigeration lines piped properly, okay, so a suction line.

P-Trap is there to increase the velocity of the refrigerant, so the refrigerant flows. Let's say it's carrying oil and it hits that trap and it goes and it slings up when it hits that it creates a some kind of a magic effect right. It's voodoo magic crap, but when it hits the p-trap it pushes there, it helps to get the oil and speeds up the velocity of the refrigerant to help bring the oil back up to the roof. Okay, proper piping practices are going to tell you to put a p-trap downstairs, put a p-trap upstairs so that way once it makes it up, it has to go down, there's a there's, a reverse trap and it traps the oil up onto the roof.

Okay, i don't do reverse traps very often, because i find that my line sets are usually pretty small half the time. I don't even think i need to be installing p traps, but i do just for a safe practice downstairs, but if you open up a copelan, insta or copeland service manuals right back here, these are old manuals, but they're actually very valuable. Um. The refrigeration manual is right here.

Let's see uh this one right here, refrigeration manual, part, four system design has lots of information on how to properly size. This is an old manual, but it's still very relevant how to properly size refrigeration lines to bring up velocity. There's. There's diagrams right there showing inverted traps onto the roof different stuff like that for proper piping.

So these copeland manuals will give you a kind of an understanding on proper piping practices for sure. That's a tongue, twister right all right. Let me see what else we got going on in here. Um, let's see you shouldn't be by no, i don't even know what that says.

Uh you did some apprenticeship for your uncle when you were 18, so you know a little okay, all right. I'm reading into a conversation going on um. What will i be having for dinner later good question? What is my wife making for dinner? My wife, she told me - and i already forgot - oh some sort of a pasta dish with sausage and different things like that in it all right. Um, let's see someone's talking about boots, i use uh timberland pro boots, uh like them forever, hey concept.

I've thought about doing this by myself, but maybe it's something we can do with the new tools channel. I thought about doing boots like ordering a couple different pairs of boots and kind of saying what i like about them. But the problem with boots, though, is that you know that's a very personal thing like you know, there's things that i like about timberland pros that maybe you wouldn't like so i don't know i've always kind of had a hard time with boot reviews um, because everybody's Different, you have wide feet, you have you know whatever. So it's a hard one hey, if you guys haven't already, please consider checking out my website hvacrvideos.com uh, merch available.

We got these hat these shirts. We got hats, beanies, sweaters uh. This is the original.
