Hey everybody: how are you guys all doing this evening or afternoon? Well, yeah, it's all evening, for you guys it's late afternoon for us, someone had asked how the weather here is in Southern California. It's actually great. It's probably mmm 78 degrees. Today, super low humidity so know when nice and sunny so spring is here officially it's it's getting definitely getting nicer outside.

So I'm not looking forward to the crazy hot summer that we got coming it's kind of funny, because my wife was just telling me how she wanted it to be nice and hot. And I didn't really like that comment too much, because even though I do like the extra work we get in the summertime, it's just you know you guys know it gets hot and ridiculous, so forgive my little sunburn. I got going on too so yeah thanks, but yeah I shaved my head today. So that's why you see sunburn on my forehead, but not on my head, so my hair was getting kind of long, so it was that time so got a couple things.

A couple questions that I already kind of have set up on a you know, piece of paper and got a couple of topics I want to cover and then I will try and get to any questions in the chat. So if you guys remember from the last one, if you guys could really really please questions to me, if you could put them in caps, lock, okay, that would really really help, because that helps myself and just in the moderator to make sure that we get to Your guys's questions, so that's my goals. I want to try to get excuse me, some more and more of you guys's questions and be able to answer them more, but also you know I got to cover the few things I want to cover too. So it is what it is right, all right, so um I uploaded a video today and I wanted to kind of correct a few things you know someone.

I had a few people point out some things about the video that I uploaded today about the bad compressor that had the suction valve. That I said was bad and the compressor - and I you know the semantics - some people kind of I wouldn't say, attacked me, but had a hard time with the way that I worded that and it had bad valves. Okay, it wasn't just a weak suction valve. It had a bad discharge valve and technically it's the little reed inside the compressor, but I used the term valves pretty loosely okay.

The compressor was trashed, basically the valves inside the compressor. The high-pressure was bypassing into the low pressure when the system was pumped down. Okay, so that was a problem, so that meant that we had a weak read and the high pressure was getting passed that read and feeding into the low side of the compressor. So again, just some of those semantics that people just got to make sure.

But I also want to make sure that I'm correct when I say things to you guys. So that way you understand. I know a lot of people know what I'm talking about, but then there's some new people too. So I don't want to confuse people on.

What's actually going on - and I do want to point out to that - that you know that suction valve test that I did is is not a very trusted test anymore. Okay and the reason why I say that is, there was a I'm pretty sure there was a copeland bulletin a while back on the Copeland CR compressors, which technically were air conditioning compressors. But a lot of people used him in medium temperature, refrigeration for our 22 and the CR compressors. When they first came out, they had a technical bulletin, saying that you couldn't do the pump down test on them, because they won't pump past five psi from brand-new and then, as the compressor runs for about three or four years, it that that pressure that it'll pump Down to actually weakens and kind of goes a little bit higher and higher.

So using a pump down test, you shouldn't make that your only method of diagnosing a bad compressor. You always want to you know, look at everything, look at the big picture and diagnose the system as a whole, so that system that I made a video on. I said it earlier in the chat that video that I uploaded this morning was actually from a couple months ago that was actually before the end of the year. I just been dragging butt on editing that video and yeah.

It just took me a while to get that all edited out and everything but yeah, so that was an older video. I just finally got to figure it out and edit it and everything so that system more than likely the replacement video will be this Friday. So - and I do see some questions in here - guys I'll get to those here in a few minutes so but yeah that was an hour 20 to system. It was time you guys saw the coil.

The coil was from 93. It was just time to replace that system and we went ahead and upgraded it and yeah everything's up and running on nothing so yeah, hopefully we'll get that video up Friday I'll edit, the other one down and get that ready for you guys. So so that was one thing I wanted to point out saw it today, as I was just kind of going through my mail. I had my a couple things that I hadn't gone through.

I found my RCS magazine that came in for April. If you guys haven't, if you don't subscribe, you get. The are SCS journal, lots of great information in there. I shouldn't put that right there because my address is on there.

So don't be a troll but yeah. The our SCS journal, if you guys don't already subscribe to that magazine, you probably should you go to our SCS org? If you don't, I think you might be able to get like a free one-year subscription. If you ever go to the trade shows and our SCS is there they've always got something going on they're saying where you can get a subscription for like a year or something like that for free and if you're a member of our SCS, then you get the Magazine automatically so anyways in that magazine, there's a great article about evacuating systems. Proper vacuum procedures is actually a two-part article, so the first part is just basically talking about a vacuum, and then the second parts gon na be talking about setting the system up and hooking.

Your hoses up and all that good stuff, so I thought that was a pretty cool article, so you guys said search but that went out and I believe you can do digital copies of that magazine too. If you guys don't like a print, I prefer I'm old-school. So I like to hold it in my hand, so that's just me, I'm just the old old-school person. I still like that.

You know my troubleshooting books and different things to be physical, copies versus, like hey yeah, whatever you want to call a copy. So, okay, so I did see a question. I'm gon na try to get to this real, quick. Someone asked me and go back up into here: mmm where's, that there we go.

How often should the cooling pads on swamp coolers be changed man? Well, it really depends on your climate. Okay, so I have a customer in Palm Springs where it's very dry and that swamp cooler. It's actually on that rack that you guys saw the video from today. It's on that piece of junk track.

It's a pre cooler for the entire rack that swamp cooler. The pads have to be changed on that every three months because it runs 24/7. It's super dry out there and have really hard water, so they get mineral deposits all over it and the pads are so bad that you can't even change like clean them. They just get calcified ridiculously bad, so it all depends on your water, water, quality and - and you know where you're located in, I have other places like here in the Inland Empire, where I'm at in Southern California, that we can go probably two years on some locations Where it's not as hot you know, the swamp cooler only runs you know, essentially when the exhaust fans are running or something so yeah.

It just depends on the area, but you know once they become so calcified that you can't rinse the calcium off and they're. No longer soft and you can't clean them, then it's time to change the pads and on a swamp cooler too. You know you're better off with as cheap as they're made, especially the ones that have like the straw pad you're, better off doing a full overhaul change. The water flow a temperature controller if it has one the belt oil, all the bearings and change the pads drain it and possibly change the water pump.

At the same time, it's not a huge expense and those parts fail so often that you might as well when you're doing a tune-up on it. You should just really change those. That's that's the way I roll, because it they last a lot longer. That way.

Now my particular customer that I have to change the pads every three months. I don't necessarily change the water pump every three months, but it's more or less on the customers, where I have to change the pads like every year or every two years. Then it's time to change the float and the water pump and all that good stuff that that's just my opinion to each their own. You know, I don't want you guys to push products on people that that they don't need.

So you guys have to make those judgment calls yourself. So okay go down here, alright! So oh! That was another question that came up. Forgive me, I'm sorry! If I forgot your name, you started in the beginning of the chat. Actually, I can just go back up here.

It was Frank. Bradley asked me about my methods of changing motor sheaves and motor pulleys and that kind of stuff. Okay, so I have a pulley polar from a very long time ago. I gosh, I think it was my dad's when I started working with him and it's lasted me forever.

I still use it to this day, so I can't tell you the name of it because it's not on there anymore, but it's just a standard puller. Okay, just your standard three arm polar you can adjust them to the different lengths. This thing will get pulleys and bearings and all that good stuff off there's a company. Actually, who is it? It's called the the tool is called the black max puller it's made by CPS.

You can get it at your local supply houses. I've seen it. I haven't used it. I don't know if it'll last as long as this one, because this one's last 15 plus years but yeah CPS, makes one it looks pretty decent.

I think they've got some newer ones that have new technology and they got Springs and different things in them. I have also seen them at my local hardware stores not like a cheap, cheap, Harbor Freight one, but I've seen some other ones at local hardware stores that also have spring mechanisms inside of them and different things too. So that will will definitely do your job when you want to pull anything off, whether it be a bearing another thing too, if you're changing like a pillow block bearing this is more of a visual, but I can kind of describe it to you a little cheat For a pillow block, bearing is depending on the bearing size like if what you want to do is go get a piece of black iron, a galvanized pipe, that's bigger than the shaft just bigger than the shaft. So it can slide over the shaft and you can put it on the bearing you know and then just tap the the black iron or the galvanized pipe and it'll push the bearing further onto the shaft.

Of course, before you do that, you want to sand the shaft and clean it up on the other side of the bearing once you get that bearing pushed further on the shaft, then you can sand underneath it and in front of it and then you'll be able To slide the bearing right off so that's another method for changing. Like pillow block bearings, it's it's not very common that we get to change, pillow block bearings anymore, at least with working in restaurants, because they just change things. Now. Nobody wants to put $ 1,200 into an exhaust fan when they can go, buy a cheap.

You know captive air, one which I mean they last for a while you know so they get them buy. So hello, it's everybody! That's coming in. I see you guys all saying hi so Manuel you said: is there any way to help quiet the vibration on a barred wall unit that is on a trail office? You know, but it the vibration is coming from something. So you've got a blower assembly.

That's out of balance, you've got a condenser fan. Motor, that's out of balance or you've got something that's wrong in your compressor. More than likely that's causing that unit to vibrate, it's not the unit itself. You need to investigate why it's vibrating and that will solve your problem.

So exactly I find what's vibrating and then change it. So yeah auto parts still the all those pulley pullers. I don't know it might get the job done. I'm not a fan of spending a bunch, but Chris H, you want to know my thoughts on our x11 flesh.

So that's actually on my topic right now so and I'm gon na go ahead and cover that. That's something else that I was going to cover. So I had some other questions on my video that I posted on Friday, which was a grounded compressor. Okay.

There was a lot of things wrong with that AC you guys. If you watch the video you saw that I had a big air flow problem. Okay, on top of that, the low pressure controls between the first and the second stage were swapped. So if there was a low pressure problem on the second stage, which is the compressor that I replaced, the compressor wouldn't have shut off because it was monitoring the first stage right then, on top of that, you guys see how close that condenser was to the wall.

It was about 10 inches away from a wall and that's a 12 ton unit. What else was wrong with it? Oh and I had a massive air flow problem. Someone had brought up because I pointed out, I think, in the video that we had like one point. Three, eight or one point: two: eight static pressure, total external static across the the package unit and somewhat Dmitriy.

Thank you so very much man. I really appreciate it. So someone had pointed out that you know well packaged units are meant to run 1-inch estatic. Yes, a lot of packaged units are, and some of them were meant to run more okay, but they're not meant to run one.

It's just static on the supply side. All right that unit had one over one inch of static just on the supply side and the return side of that unit actually wasn't ducted. The return side was pulling attic air. So that's why you had no pressure drop.

Basically across the return, the only pressure drop was going through the the the curb adapter. Basically, then, once it dropped out of the curb adapter, it just went straight into the attic and then they just have open grills inside the ceiling in the restaurant, so that unit had a lot of problems. Now, let's get back to the the compressor replacement. So when I change the compressor on that, I I didn't have room in the system, I made a judgment, call that I wasn't gon na put in a suction filter, dryer, okay, and the reason why I did that was because, if you install a suction filter, dryer Majority of the time you're supposed to go back and replace it.

If you come back and you find out that you have no pressure drop, it's okay, you can leave it in, but most of the time it's gon na plug up right. So I had to make a judgment call because I could get that thing in there, but I'd probably have to pull the top off the unit to replace it. So I decided to run without a suction filter. Dryer on that system, I did put a high acid.

A spoilin 16 3hh, so a 16 cubic inch 3/8 inch line size with the HH core, so that was the high acid core. I did put that in there now. I did not use any flush in the system and I'm gon na tell you guys why ever since I heard well, I was kind of already getting a little skeptical about using these flushes and different things. Okay, because I never really saw any big results by using a flush, even like an acid neutralizer, I never got a big big result out of it, and I was always kind of curious as to what I was adding to the system and the flush.

It's really easy to to put flush in there and if you don't do it right, you know it could get stuck in the system. So I was, I was very skeptical about using the flush and then, when it came to the acid neutralizers like the acid scavenger or whatever you know, one of those new Calgon products. I just I don't know I felt uncomfortable putting him in the system because you know I remember coming up in the trade I was taught you were never supposed to put anything in the system, but then all of a sudden, we we really started listening to these Supply houses and the supply houses were telling us. Oh yeah use this stuff, it's safe, its manufacture recommended, and so we just started using everything.

Now I got to be fair and say that I never saw a real problem from using flush and I never saw a real problem from using an acid neutralizer, but I just didn't feel comfortable using them. So I was getting kind of leery about using them and I was really starting to like lean off of it and then, when I heard the first time I heard John Pasteurella from refrigeration technologies on, I think was Brian oars podcast or I think I'm pretty sure That was the first time I heard him and he was really talking about what those chemicals are and what and - and he was just breaking it down. It just really set me over the edge and I just kind of decided to stop using those. Unless I had to now they're I mean I'm not gon na lie and say I haven't used them since that podcast I just really been coming back and taking it easy on using them in this particular system.

I really thought it wasn't that contaminated the comfort the oil was contained in the compressor. I think there might have been like five ounces or four ounces of oil that was unaccounted for it right. I think when I, when I poured the oil out of that compressor, so it's just a couple ounces. So I really didn't think that that the system was contaminated enough to put a flush or an acid neutralize in there.

Okay, so I'm not knocking anybody for you. Some flushes or acid neutralizers, I'm not gon na knock you for using dye, I'm not gon na knock use it for loot using a leak sealant. Okay, it's just not what I want to do. I don't want to be putting that stuff in the system.

If I don't have to okay - because I just don't know - what's gon na happen later, especially with these new systems - they're super high efficient - I just I don't want to cause problems, so my outlook on it is I'm gon na try not to use any neutralizers or Flushes or anything in my system, so you know to each their own. You know I'm not judging anybody for doing it. So yeah Frank, I I mean you know Frank asked: wouldn't your vacuum remove whatever remnants of the rx 11 flush, you would think so. But what what is that liquid? What kind of what kind of residue is it leaving in the system? That's what I want to know.

Yes, you know the liquid refrigerant right, it would probably boil off sure, but what residues is it leaving in there? That's what I'm afraid of so you know I. I would really like to see some science behind it. I've definitely heard mr. John Pasteurella from refrigeration technologies.

Talk about it, but you know I'd like to see some science. I you know, of course, new kalgan's gon na tell you that oh yeah, it's safe and all those different stuff, but I don't think it was them. But there was another company out there, one of the big manufacturers that was pitching - and I think I talked about this last time. They were pitching something that you put in the system, so you don't have to vacuum it down.

It was like this can of dry stuff. It was for moist systems, you'd like sprayed it in there and it's supposed to - and it's just like, I'm so sick of these guys telling us that these things are safe, because that's baloney, you can't you know whatever that stuff was called. It was like easy dry or some weird stuff and a can, and I don't think it was new Calgon. I think it was another company and they were pushing something, and I just I don't trust those guys anymore.

So you know I feel a lot more comfortable. If I get a compressor manufacturer like Copeland, saying something to say, then I feel a little more comfortable about using it. But you know until until they're willing to stand behind it, I'm kind of a little leery about using that the flushes and the neutralizers and stuff. So Manuel in the HAR asked, if there's any classes that are being offered this year, I recommend a take.

You know off the top of my head right now. I don't know it depends on your area. Look up your local RSES chapter, our SES org find out where they have local meetings. Those are usually free classes unless it's like a seminar and those might cost some money.

But you know here: in Southern California we have the energy energy education center in Irwindale and then there's a sister to that SoCal, gas and Downey, and they offer all kinds of subsidized training classes that are great. It's through. I hackie. I h AC.

I you know so that that's kind of all off the top of my head, you can email me. I can try to send some more stuff. Maybe I can try to get them all written down and teach you know bring them up on my next live stream or something so all right. What do you think compressor manufacturers are not giving? Oh? Why do I think compressor manufacturers are not giving insight about chemicals? I mean at least was I've heard from my Copeland.

Reps is, is they don't mind approving a chemical for use in their compressors, but the way that it was told to me - and maybe this is complete baloney? But what Copeland has told me their rep was that they put a lot of money into researching and investigating chemicals. So if the manufacturer is willing to front the cost for that research, then I think Copeland is okay. They'll build they'll follow through and if it comes back positive, then they'll I could be talking complete crap right now, but I thought that's what I heard. I thought basically the amount of money that Copeland puts into it, they're not going to do it for free, and so basically I think that was the gist of what I heard.

So if the manufacturer was willing to front the cost and Kaplan thought it was a good product, and I bet you that they would approve it or at least give it a look and find out if it's safe for their systems. So is there any training simulators for AC HVAC? I don't know Abraham, not that. I know there is there's some apps and different things. You can do.

Yeah there's go to you. You know Brian or is a really great resource for a lot of the training stuff. To HVAC our school comm, he has a lot of great training resources on there too, for you guys that want to get online training. If you don't already subscribe to his podcast and check his tech tips out and stuff like that.

Okay, so you said: use the copper glue for drain lines because you're in New York City - and they have to be copper in some places - require a fire watch and burn permits. I wouldn't trust that stuff with pressure, yeah yeah I'd, be a little leery. I had one of the people, and - and this is gon na actually segue into something else that I want to copy or talk about, is and guys if I'm missing your guys's questions, you're not gon na make us upset, put them back in the chat again. Okay, because I'm gon na talk for a minute, I might miss some more so just keep putting them in the chat and we'll get to them.

Okay, so I want to bring up to you guys. So as as my my youtube, videos and my live stream gets bigger right. We have quite a few followers now and we have you know a little bit of a presence, small little presence and I and I kind of make videos in my little niche, which is restaurant refrigeration, I'm starting to get a lot of manufacturers reaching out to me And a lot of the people, I'm gon na, be honest with you. I don't give the time of day.

Okay, if I, if I will converse with the manufacturer, I mean I'm polite, I'm not rude, but people that are selling like wanting to send me these weird products like I had a guy that wanted to send me like laundry additives, and it was weird it was Just just weird stuff, like deodorizers, and we just I'm, that's not my thing: I'm not pitching products. Okay, I'm not saying that I'll! Never work with someone okay, because here starting in May yeah, there's gon na be a sponsor on the the videos in the podcast okay. But it's someone that I believe in I'm not saying that. I trust every single thing that they do but they're a good company and I honestly trust them.

Okay, I'm only willing to work with people that that aren't selling snake oil and weird things that I wouldn't use myself. I'm not gon na try to push things on. You guys, okay, so if you do hear me talking about something you know it's, it's I'm not endorsing it completely, but I'm just not gon na be pushing weird stuff on you guys. So just know that, okay, you know - and I don't want to be - I get some companies like, for instance, there's a tool manufacturer that I'm technically still working with, but there's no money involved.

They just send me some tools to check out and stuff like that, but you know once I made a video and like showcase their tool, then they they sent me an email asking me to change the title of my video and and and put links to where You can buy their tool and you know just that's not what I want to do. You know like that's, that's not how I want my channel to go so I'm gon na. Do this my way and I'm gon na try to not bombard you with a bunch of BS and weird crap and stuff like that, so so, hopefully you guys can trust when you see something that I say is an interesting product. Okay, like, for instance, you know that field piece s, man 480.

I really dig that product. Now, it's not the it's a it's. The new manifold that was just released. I've been beta testing it with a bunch of other, really cool guys all over the United States and we've all been testing it and beatin it up and dropping it and kickin it and hosing it down and all kinds of stuff to try to test the limits Of it, I'm not saying that that thing's the best tool in the world but it'sit's a pretty good quality tool.

I mean I put it through my abuse and it works great. I'm not getting compensated for them by that or anything like that. You know, but I just want you guys to know that I'm not gon na try to push weird products on you guys, so all right I'll get off that rant. I don't know why I went into that for some reason, but alright, hey.

I want to point out: I'm gon na put it in the chat right now. I did see - and I don't know if he wants me to do this or not, but I'm gon na go ahead and put this in here control V. I noticed that Zak Co de is gon na start a new YouTube channel. I just put the link in there.

You guys copy that link down and go subscribe to, that'd, be cool and don't ditch my my stream right now it's ago, but go subscribe to his new channel. It's not going to be an HVAC related thing. I think it's just going to be more just general talk about whatever, so I thought that was worth putting in there so check that channel out for him. I'm sure he would appreciate some subs to that.

Okay, now I'm gon na try to get some of your guys's questions again. Okay, so if primetime man, you know dude, I'm old-school too, but you're gon na have to make the jump dude because digital is I'd say in 90 % of the time. Digital is better. There's a small percentage that it's not but there's a very large percentage of where it's better, the biggest downside to digital gauges is the.

What do you want to call it the what's it called how fast they react like it's right on the tip of my tongue. I can't think of it right now, but so, basically, if you're doing a pump down test on a compressor with a compound gauge, you can watch the needle drop as the system pressure's dropping with a digital gauge. It takes a second. It's like you know, a half a second behind, so sometimes you don't get to see it drop.

5. 4. 3. 2.

1. You see. 5. 1.

You know you don't see that that real quick movement but other than that man digital. You can see a lot more with digital, in my opinion, ok, so I I do think that people need to know how to use compound gauges, okay and how to use a standard temperature pressure chart. But once the technicians learn that I think that digital is the way to go so personal preference. No, you know no, not judging anybody but Jo 65 thanks so much man.

I really appreciate it: okay, uh! No Gary black jr. man use the field PSS man's. They do find in I mean I'm not gon na they're, not rated like waterproof, but they can they'll be fine in the rain. So all right, you can get them wet all right.

I mean you wanted your best to keep them out of the rain, but you know you: can you can get them occasionally wet? They can get drizzled on, they can get, they can handle some water so and so can a lot of the other ones too. But again I'm not saying go drench him in water, but I will tell you guys that in the beta test we were told to hose those things down and there's a lot of guys out there that were just hosing, the damn things down and they work just Fine, so I'm not saying to go dip them in water, but they work good, okay, reefer tech mark. You said your industry is just now starting to go to three phase Scrolls. Could you go into properly checking a scroll for okay, grounded, etc, yeah scroll compressors? That is a whole thing.

I'm gon na I'll try to put that on a thing to make a video on those reefer tech mark, okay and I'll, try to make an actual dedicated video on checking out scroll compressors and how scroll compressors work. You know it was actually brought up. Zack had asked in the last podcast in the last livestream Zach from HVAC shop talked. He had asked if I was gon na have guests on here and I think that'd be a really cool one.

If maybe we can have - because I want to if, if I end up having guests on this livestream, I want it to be guests that I don't want it to be the same as everybody else's live streams right. I don't want to have the same guess as everybody else does, or even at least if I do have a guest that someone else already has. I want to talk about things that are in my little niche. You know working with like commercial refrigeration and you know three-phase stuff and different stuff, so maybe we could work something out with like.

I have a local Copeland rep here or something like that. Maybe I could work something out with them so but yeah I'll definitely try to make a video at a minimum on three phase: compressor scroll compressors, how they work and different stuff like that. So maybe we can get one cut apart and you know all that fun stuff I'll reach out to Copeland on that. Okay, so, let's see no comp GB said have I ran into any more heat craft issues with the carbon flakes? No that that video, where I showed you guys the carbon flakes, I haven't seen that one happened again yet because I did do a couple more coils after that, and I opened them up and no, they weren't like that that one was a hideous one.

So that must have been a Friday so and they just took their time yeah. I they're shown Mac yeah Copeland. I I've read something about that: a fake short to ground continuity, readings on Copeland scrolls. You also got to be careful too, because I haven't cut that compressor open from the beer walk in from about three weeks ago.

I still have a sitting on my shop, but that one is a three-phase compressor. That was the one that had the external overload on it, and I want to cut it open to figure out if there's an internal overload too. But I did find out that that compressor has what they call its wound with a Scott T winding, which is different, because even though it's three-phase all three legs will not equal each other, so you have one leg: that's got a greater resistance value versus the other. Two legs, so you do have to be Fona in.

For some reason, I thought I read a bulletin on a scroll compressor having that before or something, but I have to do some more research, so you got to be cautious about combing out. Compressors Copeland does have a tech bulletin about how inaccurate a mega ohm meter is on a scroll compressor. They definitely have a thing on that and Copeland's basic stance on mega ohm meters is that they should be used for preventative maintenance measures and not necessarily like a walk up and say this compressor is bad. They want you to to trend the data, to confirm that a compressor is going bad and if you know how a mega ohm meter go, it works too.

If the. If the system has a lot of moisture in it can read a high resistance to so you just have to understand how to use your tools before you just jump up. So I'm saying, if you go by that sup Co mega ohm meter that you can buy at the supply houses. You know you can't necessarily just trust that thing, because it says bad because it can read danger or whatever, when the system has a lot of moisture.

In it, so you got to be cautious about diagonally. You know condemning a compressor just because that things that same reason, where I was talking about at the beginning of the stream about the suction service valve pump down test, you can't just diagnose just on that. You have to look at the big picture and look at everything: okay, evaluate the amp, draw another point, I'll recover it again, real quick, because I know there's more people in this stream right now. We've got a hundred and thirty people in here right now.

In the beginning, I was covering the video that I uploaded today about the suction service valve test, and I wanted to point out that I did say and even on the title, the video I wrote bad suction service valve right, weak suction valve or something it did Have a week section service valve, but I wanted to point out that the gas leaking by that I was talking about why the pressure was rising on the suction side was actually because the the discharge valve was weak and it's more or less semantics. You know I I want to make sure that I'm accurate for you guys, but someone had said it to me and it's like it's really not that big of a deal it had bad valves, but you know I I do want to point out that it actually Had a weak suction valve, but then it also had a bad discharge valve and technically it's the little reed inside of there that was weak and the gas four was leaking from the high side into the low side. So I just want to make sure - and you guys understand something too - I'm human okay - I I don't want these videos to be like rehearsed and and that kind of stuff. Okay, so you guys are seeing what's happening and I don't necessarily always say the right things, but if you guys are paying attention to the video and looking at everything, sometimes you'll know what I mean you know.

I may miss speak about something and I try to correct it. Try to catch it in editing, but sometimes I don't so. Okay have I ever seen a single-phase condenser fan motor running in Reverse, with a good run cap. I know I've seen the single-phase compressor running in Reverse, for sure I don't know if I've ever seen, one with a bad run cat or with a good run cat, though that's an interesting one, yeah a beer can cold gets you pretty close with experience Andrew I Mean you know that that beer can cold thing is one of those things.

That's your said to be a hack. If you use beer can cold right, but that is a vital sign. There is truth in that. I don't want you to go, diagnose the system and say because it's beer can cold the suction line.

Good, you know you're good to go, but I'm also saying that you know if, if you know how a system works, you can use that as a troubleshooting method. You know you can some of your things that you do. You know you can basically say hey. This thing is um.

You know everything's going good, but then but um you know everything's working. Okay, it has a cold suction line. It's got a hot discharge line. It's got a warm liquid line.

You know you're using vital signs you're looking at the big picture. Okay, so sometimes you may do that instead of putting service gauges on a system. Now, I'm not saying that's the proper way. You should always charge via superheater subcooling.

That kind of stuff, but if you're just doing a quick check and you're walking over doing a p.m. and the PM, doesn't call for putting your gauges on every unit. Then you know grabbing a suction line and grabbing a discharge line and knowing how warm and hot and cold and different things those things should be once you get to know a system, you know that's not a horrible thing to do now. I'm not saying beer can cold is the way right way to diagnose, but those are vital signs.

So there is some truth in beer. Can cold? Okay, don't blow the internet up with what I just said, but nasty yeah, guys that are just coming in it's. I got sunburned this weekend and then I've got the white head because just before the stream I shaved my head so because I had my hair was getting really long. So yeah I got sunburned on my forehead.

It was my wife's birthday yesterday and we went down to Laguna Beach and had breakfast with my sister and my parents and stuff so, and I was out in the Sun for about an hour and I got fried so. This is one of the downsides. I wear long sleeves, I'm wearing a short sleeve right now, but I wear a long sleeve work shirts all through the summer. So every time I go outside my arms get sunburned now too, when I'm in a short sleeve.

So it's very interesting I used to have these horrible farmer's tans that were permanent. You know my might. It still got a little bit of a farmer's tan there, but, like I would turn you know, white right here and I was worried about skin cancer and all that stuff. So I wear hats and weird things now, but of course when I'm on my personal time, I don't have my stupid hat with my head scarf and all that fancy stuff.

So all right, okay, I'm gon na, go to some more questions that I had from emails. Okay, okay, trade, schools and education, so someone said: hey: do you recommend going to a trade school? Do you recommend learning without going to a trade school? You recommend Nate. You know I've been getting those questions a lot. I've said this before any education is better than no education.

Do I think that a trade school is gon na teach you everything you need to know to start tomorrow. Know someone who goes through trade school is not gon na know everything they still need to go through a proper apprenticeship. Okay, I have a guy, that's working with me, and the plan is three to six months. He's gon na be riding with me for at least three to six months, and maybe longer it just depends.

Okay and that's just how it is so, he finished trade school he's a really smart guy, and he, you know, he's gon na be riding with me for three to six months, depending on how things go and that's just how it is and and I'll bill for What I can with his time, but I can't bill for all of his time - that's just how it is, and that's just something I have to accept as a business owner. So I'm not angry that he doesn't know everything out of trade school, so trade schools, not necessarily gon na teach you everything, but trade schools are valuable. Okay, they're, not horrible, they're good, but I will say you need to interview your trade schools. Ok, don't just assume because they have a cool website that it's the best school in the world, talk to people, even if you're, an HVAC or a person - that's not even in the industry yet, and you want to get into the trade call, the local supply houses And ask them hey: where do you hear good things about trade schools which schools do you hear the best about call refrigeration and air conditioning company in your area, even if you're not gon na work for them? Just ask him: hey, I'm interesting getting in the field.

What trade schools do you recommend if someone calls me asking that I'm gon na answer that okay, so you still need to interview the schools that you're gon na go to whether you go to a community college or a private trade school I'd be very, very cautious. I always say this be very cautious about paying tons of money up front for a trade school, because you don't know how it's gon na work out. I like the community college programs, but there's some that are bad too, but the cool thing about community college programs. You can usually do night classes and you can pay a little bit at a time and you can work while you're going there.

So if you can work something like that out with a trade school, I think that'd be better. Okay, so same thing goes for like Nate training and any kind of certifications is Nate. Training gon na make me more money, no doesn't make me more money. Okay, I'm Nate certified in a bunch of different things.

It doesn't make me any more money, but it keeps me on top of my education to maintain my Nate certification. Yes, there's a little bit of racket involved with Nate, because you have to pay every two years a couple hundred bucks. Okay, I can deal with that, but it maintains my education. It makes me continue my education to maintain my NEET cert.

I have to take classes. I have to go to my RSES classes. I have to log my hours that I teach you know that I that I take classes and different things like that, so any education is better than no education. Alright, um, let me see what else I'm missing in here.

I got some more stuff. I want to cover, but I don't know: oh okay, I see what's in one okay, that's that California lifestyle huh Gary yeah. Why have manufacturers like Traulsen stopped adding ports to units? Rafael Gomez? Okay? So it's all about money, but money, money, money, money, okay and they have the excuse with the AR 290 systems that they're not adding ports to. But that's baloney.

Okay, it's all about money if they can save ten cents a unit they manufacture. Ten thousand units a year, they've saved a bunch of money. Okay or ten million units a year, they've saved a bunch of money. You know it's it's it's all about money.

Now, there's also the thought that you know, because it's such a small system and there's truth, because it's such a small system, they want you to think before you put your gauges on it. There's truth in that okay, but you know it's. It really comes down to money. That's why all these manufacturers don't put service ports on the unit because they can charge it with the machine they can laser weld the line, shut or Sonic, well that whatever they use and then move on, and it saves them that much money on manufacturing.

So that's exactly why manufacturers don't add ports to units. Okay, let's see what else I got going on yeah what else guys in the chat I saw that there was a message deleted guys, let's not let's not bash each other. Okay, let's try to keep this civil. I know you know some people don't have good opinions of other people and different things.

Well, let's try to keep it civil in here. Okay, I definitely don't want my streams to be drama. I want to try to help everybody as much as possible. So, let's try to keep it to a minimum.

You know just try to be cool guys. Okay, just Russ my video last week about people not doing their jobs. Can I expand yeah. I went on a rant last week in the video where I was talking about a restaurant that had poor ductwork on the HVAC system.

I had, I should say, the air conditioning system and then it also had poor ductwork on the exhaust fan system, and this restaurant was built within the time frame that had to pass all title 24 codes and had to be inspected by the city. And I basically raised the question: whose fault was it? Was it the engineer that designed the system? Was it the technician or the serve mechanical contractor that installed the system? Was it the code inspector that inspected the system, or was it the third-party verification company's problem that verified that all the system was correct? This is a very common thing in our industry. Okay, there was, there was four, let's just say, people right in essence, that were responsible for that restaurant being the way that it was. It went through four methods of verification to make sure things were done right and those four people all failed their jobs, because that restaurant is operating with horrible ductwork with you know, and it's very energy-efficient.

They lost a compressor with you know: they've got all kinds of problems, they've got smoke problems in their kitchen and then on top of that, I got to also point out to that particular restaurant. Last year. They called me in the middle of the summer when, when we had a massive thunderstorm and they they said, exhaust fan stopped working, a fire, sprinkler went off and someone pulled the ansel system, so I'm thinking they had a building fire. So I run over there get to the restaurant.

The fire marshal was there, they had the place closed down, there's water everywhere, and I'm talking to the fire marshal and he's tell me this is that same building that has all those ductwork problems. He was telling me that what happened was the exhaust fan had had a problem. There was definitely something wrong with the exhaust fan. It was running slow, okay, that was a whole nother issue, but someone installed all the wrong fire sprinklers.

In the kitchen, the fire sprinklers temperature was too low and the fire marshal said these are all the wrong sprinklers. So, on top of all that right, so then that one fire sprinkler went off and one of the cooks got scared and he pulled the handle system and set off the ansel system. So on top of all the ductwork problems, they also installed all the wrong fire. Sprinklers at that location too, so what a cluster after that restaurant was and it went through all the proper methods it was permitted.

It was you know, everybody did what they were supposed to do as far as pulling permits and getting approvals. But then nobody followed through that inspected that building and nobody followed through that installed the equipment. I mean it was just a mess and that's a very common thing here in California, in the United States and even in Canada and other countries. Everybody has reached out to me on that video.

When I went off on that rant and said it's not just there. It's everywhere, like that's, just horrible, that we can't do our jobs. You know you know that a lot of the the third-party verification here in Southern California. So if we want to get a permit on something, we have to go through hers, Raiders Herz Raiders are basically a third-party verification company that comes in and made sure that we did our job right right.

It's very interesting because the point that the the fact that we have to have a third-party verification company basically tells us that we're not doing our jobs right. We can't be trusted and that's horrible, that we as contractors and technicians can't be trusted. It's just, but it's not just us, it's all trades. It's just a horrible thing.

I don't know the answer. I have a lot of opinions about politics and all kinds of things, but I do not have the answers. I mean I'm just yeah, it's crazy. So, okay, let me see what else I missed you have.

I thought about starting my own podcast, Dimitri, hey guys. I want to point this out. So yes I'll answer that right now, Dimitri anybody, remember McDonald's in the late 80s Early 90s having these cups. This is from McDonald's from like 1990 to 1989, somewhere in there, his little McDonald's cups with Snoopy and whatever right.

This has nothing to do with HVAC, so I was cleaning out my wife's grandmother's house and apparently they collected those cups. So I've got like a set of like 20 of those cups, and I remember those from when I was a kid and I love those things they're, so corny looking, but they you know. The funny thing is I've. Had these things, they're glass, I've had them for two years now and I wash them in the dishwasher everyday and that the the paint or anything is not wearing off the cups.

It just shows it's probably cancer-causing and all these bad things, but these things are lasting forever. So, alright, let me get back to let me get back to these. So the question have I ever thought about starting my own podcast, Dimitri yeah dude. It's just one of these things.

I am gon na start a podcast. I've already got the domain, I'm paying for it. I've got podcast hosting set up. It's just a matter of me.

Recording it. The podcast is going to be called the absence of heat podcast yeah. I've got everything set up, I just haven't done it yet. So, yes, I am gon na.

Do it it's just a matter of me finding time you guys understand something. You know I work a full-time job. I run an HVAC company with my dad. We have employees where you know we have normal normal business.

I have a family, I have two daughters and a wife, and you know, and then I do these videos and these live streams, and I'm just trying to find trying to juggle the time to make sure that I can still spend time with my family and different Things, but yes, there is a podcast coming. So that's. Why me that's why I bought these fancy mics and this fancy mixing board. You know see if I can pop this thing up here: real quick there we go close and transfer over.

That's why I have this funky mixing board this road fancy mixing board in this, that I'm using in different things - and I have another mic just like this, so I can have guests and different things for the podcast. You know I am gon na. Do a podcast eventually, it's just a matter of me finding the time to do so, and I will do it. So it's just taking me some time to get to it.

So you in transition back there there we go so yes, it will come for sure. Just a matter of me getting off my lazy butt and doing it, so I could DJ in my off time there you go okay, so best product to do an acid test or burnout test. Spore lynn has a kit. It's a little acid test kit.

You pour a little bit of the oil in a vial shake it up, and the oil will change color when it's mixed with that. You know whatever product refrigeration technologies has got an acid test kit and then also there's the the quick acid test that you have. That little, that paper and you put it on the Schrader and you poke it on there. I think it's made by quick or something like that, so the quick one I that would be the quickest little easiest acid test to do, but the most high quality acid test you can do is probably follow that spoilin, chemical or the refrigeration technologies one one of Those two - it probably the best one to do an acid test that I would trust the most so yeah that'd be an interesting idea.

Andrew Andrew Hicks is saying he wants to be Chef Ramsay and go around to companies with bad reps and scream and throw stuff until they figure it out. Yeah that'd be an interesting idea. Get companies working, you know, make a reality show out of it. There you go Andrew you should you should figure that out.

Do you to make a reality, show you can make millions you'll be a millionaire. Just just give me a million when you start making a bunch of money. Okay, a team Adam any tips to a new HVAC YouTube: dude. Okay.

So that's that's a great question Adam and I'm gon na I'm gon na. Tell you to you guys anybody that has questions about making YouTube videos or a podcast right reach out to someone. That's doing it if you guys have questions about what gear I'm using, you don't need to go, buy the fanciest stuff. Okay, if you're gon na start making youtube videos.

If you have the content, people will follow. Okay, there's some podcasters out there, I'm not gon na name any names, but there's some podcasters that have horrible audio quality, but yet they get listeners, people listen to their podcast. Personally, I can't listen to some of those, because the audio quality is so horrible, even though they have you know, but but other people still listen to it. Okay, so me personally, I can't, but other people do so start with the content.

If you have good content and the best advice, I can give you what helped me start. These YouTube videos and and - and you know, sharing them with people and growing to the subs where I'm at and I'm still a super tiny Channel. We just passed 22,000 subs.
