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 cue up the intro music yo, how you guys doing this evening, hopefully you guys are all doing well welcome to the hvacr videos live stream, so uh for the new people. My name is chris, i'm just an hvac service technician here in southern california and uh. I make these videos on youtube just to share a little bit of knowledge that i have.

I started making them for my own service technicians and then quickly, uh about the second video. I decided to go and make the videos public, and here we are now it's a trip. I never expected it to do what it's doing. I never expected it to turn into this machine that it's become, but it's fun.

I enjoy it uh. It's very easy, though, to let it get away from me and i'm trying to not let it become a burden there's times you know, sometimes where it's like man. I don't want to edit a video today you know like, but i've been trying to make sure that when i do make videos, i make them the way that i want to make them and not how other people jj services. Thank you so very much for becoming a channel supporter.

That's awesome, but i really appreciate that okay um, but i try to make these videos the way that i want to make them. You know i get i and, and it's cool you guys can always send me. Suggestions, that's cool, but, like i get people saying hey, why don't you do this or hey? You should have done it like this? No because i kind of want to do it. My way you know i want to do it my way, um, even when it comes to the sponsors and people that i partner with right now, the sponsors for the stream or for the pod for the podcast.

I don't do a podcast. The sponsors for the videos are uh refrigeration technologies and spoiling and uh. Both of them are really cool in that when we started talking and everything we kind of discussed like look, i'm gon na do this my way you know i don't want to be dictated. I don't want anybody to tell me you need to do this.

You need to do that and neither of them has ever been like that they've always been great companies to work with both of them. I have supported long before they became channel sponsors uh. You know long before: okay, refrigeration technologies, i've been promoting their products for years, um well, two years to be exact, because my videos have only been going on for two years, but i've been promoting them for the entire two years and then the same thing with spoiling I've always been a spoiled user. Sportlin fan, so you know anyways, hey uh.

Hopefully you guys are doing well right now in southern california, we're having like a crazy heat wave um and it's a trip. It's it's blowing my mind how hot it's getting. I am about. I'd say: six hours away from death valley: okay, six, six and a half hours, something like that: uh they reached 130 degrees.

They set a record in death valley naca. Thank you so very much for that super chat bud. I really really appreciate that man um connor. I guess i should call you connor um, but yeah.

They hit a record of 130 degrees in death valley, that's insane, okay, uh and that's not in an attic. That's just in the desert now granted where i'm at right now, um, we probably at the highest, have hit 115 for a very short amount of time. We haven't gone any higher than that about two years ago. We broke a record and hit 120, but we haven't hit that yet, but it is just plain hot we're starting to get a little bit of humidity rolling in but again in southern california.

We don't know what humidity is it's so minimal right now? I think the humidity is like 26, you know. So if, if we get anything over 50 humidity, we lose our minds in southern california. So right now we've got some monsoonal moisture kind of rolling through we've got thunder clouds over the mountain areas and stuff, and when that happens, you usually get a little bit of humidity, especially if you're working on the low desert, like the palm springs, coachella valley area. I haven't been out there in the last couple weeks, but i would bet that it's a little bit humid out there as usual, but you know it's also very strange because we haven't been very busy and i don't know about you guys.

I think i saw someone in the chat kind of talking about this, but we um we've been we've been doing. Okay, i mean everybody's working, but it's not the same. You know, but granted california is still shut down. The restaurants are loot grinder.

Thank you. So very much for becoming a channel supporter bud. That's really awesome! So um the uh, the restaurants, aren't fully open okay, they're doing outdoor seating, which that's insane these restaurants. People are going to these restaurants and sitting out on the patios.

When it's 111 degrees. I mean more power to them. We're getting refrigeration calls from the restaurants and we're getting air conditioning calls for the kitchen, but very rarely do we actually get um dining room. Air conditioner calls which right now would be slammed normally.

So this is definitely an interesting time of year. It's definitely a whole new game to get used to it's crazy, um all right. So let me see what i got going in the chat right now: uh, oh right, on yeah ernesto too ernesto says the same thing uh phillip! Thank you so very much for that super chat. I really appreciate it.

I'm going to address this right now, just like. I normally do you guys with these super chats becoming channel supporters. It is awesome. I it is very much appreciated, definitely helps to support the channel, but those of you that don't do it.

It's! Okay, okay. I appreciate any help, but don't worry. I'm gon na continue to do these videos don't feel obligated whatsoever anybody um, those of you that do do it. Thank you so, very much.

Okay, but again, i'm gon na continue to do these, no matter what okay, all right, um. So i've got a good list of things to talk about as usual and we're going to get to the chat too, all right so uh, the last two videos that i released this last week. Uh. Let me address this too, so someone had asked me what is my normal schedule, because i do have a schedule with the videos uh.

I try to stay consistent as much as possible. Okay, so obviously we do live streams monday evening, 5 p.m. Pacific time every week work permitting so long as i can get off work in time and i release a new video two times a week. I typically do videos uh thursday afternoon, so i usually make them go public around 12 p.m.

Pacific time on thursdays and then sunday mornings, usually around uh 6 a.m. Pacific time i release another video, so you get two videos a week and i try to stay consistent with that every once in a while, i throw a bonus video in there, but for the most part, it's two videos a week. Okay, so that's my schedule that i try to maintain um. It's definitely interesting.

It can be challenging at times to maintain that schedule, but i try try my best so um kyle, h, great question, so kyle h had asked if there was any blackouts near me and yes, there have been, and actually that was something i wanted to bring up. So, right now in california, our uh power grid is being taxed to the limit. Okay, as usual, every summer, we have like what they call flex alerts and different things like that, where they start doing rolling blackouts and they go to certain neighborhoods and shut off power for certain amounts of time, because our energy grid is just totally being just. You know used up right now.

The infrastructure is just a mess we have. We we so need help with our energy grid here in california. Now, with that being said, that's on a normal summer right right now, all the kids are still at home, they're home all day, long they're doing school, they're running air conditioners, or you know, everybody's home, so yeah we're having some issues now i have not had a Power outage cross our fingers at my house yet, but they have been rolling around all over the place all around here adam. Thank you.

So very much for that super chat bud. You need to stop with the super chats adam. You can plug the overtime show anytime. You want so yes, the hvac overtime show on friday.

Don't let me forget and i'll plug it, some more here in a little while um, so uh distracted me with that super chat. Thank you very much adam. You get me all blue. My head starts to spin, but yeah, so we haven't had uh steve steven montanez.

Thank you so very much man. I really appreciate that um. So yeah we haven't had a power outage here at my area, but it's been all around me to the point that i actually went and bought a um uh a power, a backup battery for my computer, basically a ups. I think it's what it's called.

I have it yeah ups. I went and bought a ups, so that way, just in case i'm editing or something like that - it'll at least power, my computer down, but i just hooked that up just because it's happening everywhere. I wouldn't be the least bit surprised being today is one of the hottest days we've had. If we have a power outage, you know so um.

It's definitely uh something to think about, but not in my house have we had it yet so um yeah, stephen noor uh, there's definitely a lot of political issues in our state for sure, okay, yes, i agree, there's a lot of political issues, so um something i Want to remind uh you guys - and i i have to say this - every couple live streams just to make sure that everybody understands you know um. I do these videos and i appreciate any feedback you guys leave in the comments. I really do welcome all the feedback. Negative or positive, i'm totally cool with it criticism.

I i learn from criticism, so please criticize a way. Okay, let me know if you see something i should do better. It's all good, i'm cool with that. I don't ever delete criticism.

The only comments i ever delete are when someone is just plain nasty and they're bashing, other people, i really don't care so much if someone bashes me that's cool, but if someone's just being completely rude to other people, i'll delete those and the number one comment that I delete in my my videos all the time is when people try to guess restaurant names - and i know people don't mean anything by it. For the most part, people are just like hey. I know that restaurant i worked there. Here's the name, okay, guys.

I have to protect my customers as much as possible. What the normal general public thinks is nasty is really not that bad in the grand scheme of it. I typically don't work in very nasty restaurants. Occasionally we have an issue or something like that, like they had a roach issue, but they solved it.

They resolved the issue, but most people don't understand that. So i always try to protect my restaurants. I do not reveal restaurant locations ever and to the point that, even if people in the comments are trying to guess what restaurants correct or incorrect, i delete those comments. Okay, please don't try to guess restaurant names we're trying to keep these videos going and uh.

We don't want to out any restaurants or anything like that. Okay, so um we got ta, you know, keep that private, basically, okay, so those are the only ones. So i do have to remind you know, because some people try to guess all the time, and i know most people don't mean anything by it. So um.

Let me see so the last two videos that i had this week: uh the first one on the 13th was the beer walking was too warm and we had a bad contactor on that one. It was single phase in the compressor it was going off. On thermal overload after i changed the contactor, i found that the uh condenser was really dirty, so we went ahead and cleaned that condenser properly and then we went ahead and found a refrigerant leak on the low pressure control. But while i was in there, i noticed that the suction service valve was really rusted out really bad.

So that ended up being a big giant call where it spread out over two two visits and we got the approval from the customer to go ahead and get that system back up and operational. So that was a big beer walk-in and that was the one. I'd worked on that before, but the head pressure control valve had been cut out now. We really don't need those really that much here in southern california, so i didn't bother putting it back in the system.

I just leave it out. It's no big deal. I did get a lot of questions about the lamp cord going to the condenser fan motor, so that is something that i have brought to the customer's attention. But right now, with everything going on it's working, they just want to leave it that way and in the future we'll address it now they will approve it immediately.

They basically told me, look try to conserve, try not to spend a bunch of money if we don't need to fix it right now, don't, but they basically put it at my discretion. If we need to fix it right now, then so be it do. What you have to do, but you know i'm trying to protect the restaurant too. You know i want these guys to be here tomorrow.

So if i can save them a couple bucks now, i'm gon na do so we'll save that for a little bit later. I realized that that lamp cord has been there for a while, but again the customer's aware of it and it's operating it's just not my favorite thing in the world. I have a couple of those issues here and there of things that, like don't necessarily have to be fixed today. So you know we try to be as conservative as possible with these customers because, yes, i'm in business to make money and i want to make money.

But at the same time i want these customers to be here tomorrow and continue to call me tomorrow. So you know i got to look out there for their best interest as much as possible, too um, the video after that was uh on the 16th, which was sunday, the reach and cooler had the click of death. So right, when i got there, you guys saw in the video that i could hear the clicking sound of the compressor overload of the clicks on relay, turning the compressor off the reason why it was doing that was because the unit had a bad start: capacitor. Okay, the start capacitor failed now what caused the exact failure? It's hard to say for sure a lot of the times.

In my opinion, the start capacitors fail because they're in really hot ambient environments and these units short cycle, they go on and off a lot, because when the restaurants are busy they're opening and closing the doors and it wears out the starting components, that's my opinion. I do not have scientific proof to back that up: okay um, so i went ahead and threw a temporary capacitor on there just to make sure that the compressor was working. I went ahead and used a turbo lytic. 50.

Okay, a lot of people don't realize that amrad manufacturing makes a turbolitic start capacitor or turbo start cap right. All of us probably know about the the turbo 200 and the turbo 200x, which are the universal run caps by amred, great capacitors, a great warranty on them and everything, but they also make a start capacitor. They actually also make hard start kits for uh, like residential air conditioning condensing units too a pretty cool little thing, but so i used. I keep a couple of those on my truck and i use that to start the unit up to make sure that it was working and then i went ahead and went and got the factory oem starting components.

Now something in my comments that people were asking was hey. How is it that i always seem to come up with these factory starting components? Well, you got to understand that i live in a major metropolitan area and i have two of our biggest supply houses. Actually, three of our biggest the main supply houses that i use, i use rsd i use allied refrigeration and i use united refrigeration. All three of them have hubs.

Okay, rsd is actually headquartered in lake forest. California, which is about an hour from me, allied refrigeration, is headquartered in long beach, california or signal hill, which is about an hour and a half from me and united refrigeration has their west coast hub in ontario california, between those three supply houses, they pretty much have Everything that i need for all different stuff - okay, so that's how i can get these starting components. Yes, if i lived in a more rural area, i totally understand it's harder to get starting components different stuff, like that same day, but oftentimes. I can find some things, but we don't have everything.

For instance, today i was working on something: a copeland unit, controller, the little dixo looking control for the condensed unit, and i needed a temperature sensor and we couldn't find one. So nobody had it. We had to special order, it yeah. You know we have to learn to deal with that, every once in a while, but for the most part we have a lot of parts readily available here in southern california.

So now on that one, i got a lot of questions too. Why don't i use the three-in-one start? Capacitors uh subco makes them okay, it's the little three in one: okay, i'm not a fan of those and it's nothing against subco, but here's my two cents on them. Okay, you buy a three in one start: capacitor or start kit right, and it's supposed to have an overload, a start, capacitor and a relay in it. Okay and what they do is they typically have they're separated by voltage, 120 or 240.

Okay and then they're separated by horsepower. So if you buy a 240 volt or let's just say, 120 volt third horsepower uh three in one kit, it's supposed to work for compressors from third till quarter or something like that. Okay. But my personal experience has not been very good with those universal start kits the three and ones: okay, uh.

First off i every once in a while i'll use, one just to start a compressor just to see if it works, but i never leave them on there. I know some people love to leave them on and they say they work just fine. I don't have good experiences like that, leaving them on there. My experience, too, is that if you actually take the sticker off, if you actually disassemble a three in one and take the sticker off of it, that says subco there's actually a rating on the capacitor.

If you look at the rating on the capacitor oftentimes, it's not a big enough capacitor for most refrigeration compressors that you're working on. Sometimes it is, but that's just my experience and i've had an issue with that: okay, jeremy cole. Thank you. So very much for that.

Super chat. I really appreciate that you said that you enjoy my videos as a problem. Solving puzzle challenge your computer pro, oh right on dude. That's very interesting! I really really appreciate it.

Jeremy, that's really cool! Thank you! So very much for that super chat. Okay. So that's the last two videos that i had um. Oh i'm gon na address something else too, because i just said it.

If you guys haven't already noticed, i have a lot of crutch words that i use in my videos and actually spend a lot of time in the editing stuff trying to take out the crutch words. So is one of the biggest crutch words that i use the other one is okay, i'll start my video like i'll start a scene and whenever i turn my camera on for some reason i either say so. We did this or i'll say. Okay, we did this uh now that i said that you guys can go back and if you didn't already notice, you guys will notice the heck out of them.

So i edit those out as much as possible, but i it's just something in my head. I i call them crutch words and i use them all the time where i start sentences with so and okay, don't know why that's just my own issues that i have so um. Let me see what else we got in here, hello to everybody. That's in here.

I really appreciate you all that actually come to these streams. It blows my mind right now that there's 300 something people in here watching me ramble on. Thank you so very much. It's such a trip that you guys like to listen to that uh john.

Thank you. So very much for that super chat man. I really appreciate it and why is there a peepee and a peach luca? More, that's very interesting, all right um! So, let's see what we got here, uh my list of things to talk about um, a question that i get quite often okay and i'm gon na address this right now so this week tentatively, i should have hats back in stock and when i say hats, i Mean the large extra large hats - okay, you guys can find my merch at hvacrvideos.com there's a link in the show notes of this video, i believe the nightbot or the moderator bots posting some stuff too um uh adam i'm gon na answer that question here. In just a second, yes, don't let me forget to answer that question adam.

So, yes, merch is available. If you guys are interested a lot of people been asking i've been selling out really quick. I have plenty of shirts left. You guys can see.

I have a big stockpile and then back behind here, where you guys can't see, i have a huge thing set up with shirts too um, but the hats i keep running out of so i just ordered another hundred large extra large hats. It usually takes a couple weeks for them to print them for me, so, but those should be in this week. Tentatively, i should be getting those in wednesday, so they might go up wednesday evening or thursday morning, probably is when they'll go up and they'll be available. So just stay tuned for that and again thank you for those of you already purchased it.

I actually have you guys, can see uh, there's a few boxes right here, there's about seven orders that my wife processed today that we need to take to the post office tomorrow, but um. If you guys get those packages, it's usually my wife processing them. She works really hard to try to make sure that everything's correct and we get it out to you guys as soon as possible. So all right, let me see what else we got going on in the chat.

Oh, i wanted to answer that question. Adam uh, adam neal, had asked on my off time. Do i find myself constantly thinking about service calls that puzzle me? Yes, okay, so um, my other friend adam muffetch is in here a team adam joe hvacr north bill curious hvac, guys in here too. We do a show on friday evenings the hvac.

Our overtime show usually around 6 6 15 pm on the hvac overtime channel uh feel free to plug, throw a link in there adam or any of the moderators, throw a link for the overtime show in there. If you would um but anyways the reason why i brought that up was because i was just having a conversation with them, so i was off this weekend. I had another service tech that was on on call, and i had an emergency service call that came in for a location that i don't normally service. I actually used to service this location like seven years ago, but it's about an hour and a half from my shop in the opposite direction of where i normally work and that call came in and it killed me because i had to say no to that service.

Call we weren't able to get out there in time. Yes, i certainly could have dropped everything that i was doing. I was literally mid reorganizing some stuff in my office rewiring some things and i was right in the middle of it getting ready to start editing. My video for the for sunday morning and that call came in and it killed me.

It genuinely hurts me and made me sick to my stomach to have to tell that customer that i wasn't going to be able to help them. I obsess about customers now. Do i obsess about um adam had asked me thinking about service calls that puzzle me yeah, i mean i, i obsess about a lot of things uh and you know whether it be a service call whether it be being prepared for the next week. Um.

I constantly. I wake up in the middle of the night. Sometimes i lose sleep over the fact that i just wake up thinking about a job like okay. I got this job coming up in months.

You know, and it's like, i just can't stop thinking about it, and it just kills me. Yes, it does whatever that is. I have it, it sucks. It's also good too.

I guess in one way, but it sucks for me because it just messes with my head and screws me up for sure js. Thank you very much for that super chat man. I really appreciate it. Um, let's see, let me see what uh there we go.

There's the overtime thing in there right now: okay, um, but seriously the only answer: oh okay, right on all right, so i got a couple other things on this list: uh europe um. The reason why i started talking about merch was: i got ta. I keep getting this question. Am i gon na ship to europe? Am i gon na ship to australia? I want to yes, but i have not figured that out yet.

Okay, within my software and stuff, i just haven't, had the opportunity to really sit down and focus on figuring out the overseas shipping. Okay, at this time i ship to mexico, i ship to canada and i ship within the united states. Okay, i do and have plans on shipping to other countries, especially australia and europe, because a lot of people have been asking. I just haven't been able to figure that out yet okay, so stay tuned and don't feel bad.

Keep reminding me. Okay, keep sending me emails because it my brain, thinks weird and like i prioritize things and that thing kind of gets pushed to the side so definitely keep emailing me and i'll definitely work on that and hopefully get it figured out soon um what brand leak detector Do i use roach had asked i personally use the dtec select leak detector. I've probably used it for 10 plus years um, several different mod. I mean you know, actual leak detectors.

I've had to replace it a couple times but um, but yeah i've used it for many years. It's a great leak detector. For me, i am getting ready to replace my leak detector, i'm seriously looking at the uh d or the inficon stratus, which is the the newer model of the detect, select the fancier model, because it does a ppm, readout and stuff um, but uh. I i'm not going to bite the bullet quite yet, but i'm getting there i'm getting ready to go ahead and purchase another one, because it's about time my leak detector is getting worn out.

I've replaced the sensor. Many times replaced the batteries many times the wand's starting to get really wobbly, and it's just about that time to replace it so um, but the detex select is the one that i've been using for a very long time dom hand. Thank you so very much for that super chat that is awesome, uh, you're, a maintenance man for a refrigerated plant. I really appreciate the nice comments you have about my videos.

How different is an industrial ammonia, cooling system versus a commercial one other than the size? Of course well, i personally have never worked on industrial, ammonia, refrigeration, i've seen uh lots of videos of people working on ammonia, so there's going to be a ton of safety requirements, special tools that i know of for sure, you're going to need special vacuum pumps. Special recovery machines because the ammonia is just going to kill everything, but personally i have no experience so just the videos that i've seen it's just a lot bigger uh. Just like the the light commercial that i do. I don't work on anything bigger than 35 tons.

You know, i guess it wouldn't even compare to the industrial stuff. I probably would be lost if i even walked up to an industrial system like that, and i can guarantee you that i would be lost if i walked into a supermarket rack room. I'd just be like uh. What do i do so um? Let me see what else you sent me.

A video of industrial compressors adam said that um you've worked on and i do remember kind of a video adam. I think i do remember that. Let me follow back on that, but i think i remember you sending me that um. Oh, that's a bummer dave g.

Well, i'm glad for the feedback, so dave g says don't buy it. I'm assuming he's talking about the inficon stratus, that's good information! Thank you! Dave! Um, i appreciate that has anybody else have any feedback on the uh uh inficon stratus uh leak detector that i dave. I have heard from another person that they had to send theirs back in my buddy rookie refrigeration, reuben uh had to send his back in for repair. I haven't talked to him lately, though, on whether or not he's still using it um scott.

Thank you. So very much for that super chat man. I really appreciate it yeah. Do me a favor and hit the like button, guys.

I'd really really appreciate it. What's the key to finding leaks with a dtec techmate, anyone pressurized the unit to 350 with 410 and found nothing nate peterson i've never used the techmate. So i can't comment on that one. Unfortunately, all right, let's see what else uh what books do? I recommend for refrigeration, edward ruiz uh, the the one book that i recommend is commercial refrigeration for air conditioning technicians by dick wurst um.

This is the book right here. There's a link in the show notes of this video commercial refrigeration for air conditioning technicians by dick. Worse great book, not too thick and what it does is it kind of just fills in the gaps for an air conditioning technician that wants to learn refrigeration. So it assumes that you understand how heat transfers and things like that and kind of lays off that for the most part and really goes into the controls, the sequences, the components and differences between low temp and high temp, basically so great great book.

I highly recommend it. I got no affiliation with dick wars, but i did meet him at the ahr, show very nice guy, very, very cool dude, so um great. When was the last time, i saw a belt driven compressor working prime time i haven't seen a belt driven compressor in probably 12 years early in my career, i've never worked on belt drive. Actually i've only seen one at a location that i went to go.

Give a quote on and they just had belt driven equipment, i'm rather young as you as most of you guys. Most of you guys know, i'm 37 so never had to work on anything belt driven. Now i realize that in some of the bigger industrial stuff they still deal with some belt driven stuff, but i've never myself dealt with it um. Let me see what else i'm missing in here.

What brand of oxyacetylene do i use victor or uniweld mo um? I think my kit is a hodgepodge between the two. I don't really particularly pick one thing or the other, so i probably have a victor tip on a uniweld regulator. I don't know i'm going to tell you right now that i have never been happy and i've been kind of frustrated thinking about that lately i don't know about you guys, but number one. I can't find a torch caddy that i, like i mean there's.

I have a uniweld torch caddy, it's like a blue molded plastic one and it's kind of the best that there is right now because it has a cubby for your stuff. But i don't know: there's just there's a there's, a a gap missing when it comes to oxy, acetylene torches and the the caddies that they sit in and the regulators and the hoses there's so much room for improvement in those things. Right now - and i think that uh, i always kind of try to think in my head, like how could i improve this? This is this is something that i really would like to see. Someone improve because the oxy acetylene rigs are not my favorite.

The stupid covers break off of the regulators all the time, the you know the dials break, and i mean we just. We typically beat the crap out of our torches. For the most part, i mean we bang them around, we drop them. We do everything and it's just they should really be more sturdy um.

I know there's a bunch of different regulators, you know uh, i've been western enterprises start i kind of saw, but i really would like to see some of the supply houses, but western enterprises, the people that make the vn500 um nitrogen per purging regulator that i use They actually make an oxy acetylene regulator too uh. I haven't seen one in a supply house, but it looks interesting, but it's kind of weird because you don't adjust it. So i'm kind of tripping out by that i like to adjust my my oxygen and acetylene levels depending on the different torch tips that i have so. I typically braise with a number two tip on almost everything and then every once in a while i'll switch over to a rosebud tip and when i change the rosebud tip over.

Obviously i increased my pressure so something on the unit i mean on the western enterprises. One that you don't adjust, i'm a little bit reluctant to try that, but i don't know it looks interesting though so cool concept um. Let me see what brand uh. I already think.

I answered that question um. Let me see who the hell is dropping their torches. Oh dude frylock, you haven't, dropped your torches dude. Oh, i've dropped my torches off of a ladder um i've accidentally uh forgot to strap them in my van and they fall over.

In my van all the time and the regulators break one time i dropped my torches and i was so scared because i dropped them like. I think i was going up a ladder and they slipped out of my hands and the caddy exploded, like not fire, but i mean the caddy just popped and the the oxygen bottle went rolling like not far because it was still connected via the hoses um. But yeah i've i've beat the crap out of my torch caddies and then also with the blow molded plastic one. Even the bottom is starting to blow out, basically just from not even dropping it like um yeah it.

I don't know i'm pretty abusive with my tools for the most part, so um all right in the video from thursday. Who did i pull a vacuum? Oh okay, brent. I remember your comment coming through and i wanted to answer that so brent had asked me a question: why did i pull a vacuum before i change the dryer? I actually didn't. This was on the beer, walk and replayer, but unfortunately what happened was when i showed the dryer after i pulled the vacuum like i went over there and i kind of talked like hey.

We went, but no, i actually changed the dryer before the vacuum. It's just the way that i edited it. It looked like i didn't um, but yeah uh can commercial hvac experience apply to residential equipment? Like can you apply commercial things you have learned to residential units or vice versa? Yeah, definitely uh don't hesitate any of you guys to repost your questions. If i don't address them, make sure you put them in caps lock.

If i don't address them, keep posting them until myself or a moderator tells you to stop posting them. Okay, because oftentimes there's a bunch of questions that go missed in here that i don't make it to so. Please keep reposting those okay, so yeah. You can definitely apply commercial, refrigeration and air conditioning to residential for sure.

Okay. So most you know a lot of people start when they leave school, they're, they're kind of taught residential in school right. They don't go crazy into controls and low temps. Some schools do, but for the most part they don't um.

So you know the natural progression is. Is start residential move your way up light commercial move, your way up: commercial, industrial, that kind of stuff? Okay. I know some people jump and go right into industrial and stuff, but as long as you understand the basics uh you know in in the residential side, oftentimes people aren't really pushed into schooling and if they are pushed into schooling for the most part, it's it's sales. Training and stuff like that, it's not really education to become an hvac service technician.

Okay, so in the commercial side, there's not really a huge focus on sales for service techs uh for the most part in my area, there's not focuses on commissions or anything like that. You're just there to be a service tech maintain equipment, you know, give quotes and that kind of stuff. So, yes, you can definitely apply commercial experience to residential and vice versa. You can apply residential to commercial.

What's the tool on the top of that shelf gray with wires, so that gray tool is a hermetic compressor analyzer. So let me grab it so this was my hermetic compressor analyzer now, obviously there's a there's a lid to it. I just popped it off, for so you can see now what this was was you were able to. Basically, you have an ohm meter right here.

Okay, so you can check ohms. You can test a compressor. You hook on these alligator clips to the three terminals on the compressor. You have a couple different capacitance values here for a start, capacitor and basically, you select the range within your start capacitor.

So what you're doing essentially is, if you have a compressor, that's not running, you can start it up because there's start capacitors and there's a relay in here. Well, there's not a relay, but there's start capacitors in here, so you can start it up and tell if it's a bad compressor or tell if it has bad starting components. Okay, so something like this is what i would have used in the past on the video that i released on sunday. The the unit has a click of death.

In the past, we didn't have uh readily available start capacitors or universal start capacitors or three in ones, and we actually used a hermetic compressor analyzer next to that hold on. This is another compressor analyzer. This is an annie now, the one that i just put up. Another really cool feature of that one is on three phase compressors.

You can actually rock the compressor and break it loose and what i mean by that is on a three-phase compressor, sometimes and usually not a good sign, but sometimes the compressor can get stuck. I might have had this one time in my career. The compressor can pull locked road ramps and can physically something inside of it can get stuck something's really tight, or something like that and what you can do with that is. You can actually there's a selector switch on there and you can run the compressor forward and then you can run it backwards and you can do it really quick and try to break through whatever's uh, stuck in the compressor and get it running now.

I think i've broken a compressor free one time in my career and i think we we ended up going back and replacing it, but we got it to run through the weekend, basically, okay, so this is an annie. This was the original one. This is an older one. This one doesn't work for three-phase, but basically oh no, this one does yeah.

You can go reverse on this one too, so um, but this one right here, uh! No! You can't use this for three phase, that other one you can this one, you can't um, but on this one right here you can start a compressor just like that. It has start capacitors built into it. This is a really old one that one of my service techs actually gave me his dad found it at a garage sale. I really like old tools and i like to collect them.

Uh i've got a uh charging cylinder right there too, and i never actually used the charging cylinder. But one of my techs brought that to me too. So i just like collecting the old tools. All right.

Let me see what else i got in my list. Um great question that i had how do i know when i'm working on these air conditioning units, refrigeration or anything, i'm going to kind of paraphrase this question and apply it to a lot of different people? How do i know what the vitals should be? So when i'm working on an air conditioner, how do i know what the superheat and sub cooling should be when i'm working on a refrigerator? I in the the click of death video? I mentioned some rules of thumb in there. Okay, because we have general rules of thumb in our industry that we use okay for the most part - and i don't use these as a set and stone thing. But i mean it'll kind of get you in the ballpark.

Your condensing temp over ambient should never be more than 30 degrees, so the condensing temperature difference from the ambient temperature. The condensing temp, should never be more than 30 degrees higher. That's a rule of thumb, uh, newer efficiency equipment. It can be as low as 25 to 20 degrees.

Sometimes i think i might have even seen, like 18 degrees, condensing temp over ambient on some micro channel stuff. So how do i know that kind of stuff by reading installation manuals by talking to manufacturers by calling tech, support and writing down what they tell me by reading the book commercial refrigeration for air conditioning technicians? It has lots of rules of thumb in it to kind of give you an idea. I have a rule of thumb that if a system has a receiver and an expansion valve that i typically want to see at least three degrees sub cooling coming out of the liquid drain out of the condenser. I'm not necessarily looking for 10 degrees sub cooling when it has a receiver, because sub cooling kind of goes out the window when we have a receiver because for the most part we're using a sight, glass, okay, but there's a lot of variables that go into that.

So how do i know that, just from experience and doing lots of research talking to manufacturers reading installation manuals, reading textbooks different things like that is 700 to 900 microns close enough? If you want to go home, ricky, that's a great question and i can't remember if you're the one that asked me, but i am going to address the microns right now, because i had someone ask me that question so um, i'm trying to find it. So i can mark it off. Let me see where it is here. I want to try to mark these questions off that i've actually answered.

So that way, i don't forget yeah here it is right here. So the question that was asked to me in my chat or on an email, i can't remember what was on a self-contained ice machine, how low of a vacuum do i pull and what is an acceptable decay rate, okay so and that kind of goes for your Question too ricky how low is low enough all right. So we know that in our industry we have a rule of thumb that we should see 500 microns right. If our vacuum pump needs to get down to 500, microns maintain 500 microns and then we shut it off and we do a decay test.

The decay test is how fast the pressures are going to rise within the system. The micron level is going to go up. Understand something: i'm not a genius or i don't know everything when it comes to evacuations, but there's a couple things i do know number one: every system leaks: okay, there's not a system out there that doesn't have a leak. We just have very low leak rates.

Okay on some systems, so uh, the decay test is when your microns are going up after you've shut off the vacuum pump. Now, there's a certain method. Okay, you have to make sure that you isolate it in a perfect world. You don't want to pull an evacuation through a manifold set.

You want to pull and use an independent micron gauge that way. The manifold set doesn't have potential leaks and different things like that, but that's a whole other argument to be made. Okay, so how low is low enough for the most part, the rule of thumb is is on air conditioning systems. You want your evacuation to go between below 500 microns or right up 500 microns in minimum okay and you want to decay test and when you do the decay test.

Typically, you don't want the the pressures to rise above a thousand microns. My rule of thumb is within 10 minutes. Okay, now um. Eventually it should slow down on the rising.

But when you turn a vacuum pump off right away, it's going to rise, pretty quick, but you know my rule of thumb is: is that basically on an air conditioning system, i want to get it to 500 microns and i want to do my decay test and I want it to hold under a thousand microns for 10 minutes, at least okay, so that would be my test on that now, when you get into refrigeration you're actually supposed to go lower, especially when you get into low temp refrigeration. So two to three hundred microns with a decay test, typically around 500 to 750, as my rule of thumb, for about 10 minutes too. If you can keep it under that 500 to 750 range for about 10 minutes, when the vacuum pump shut off. For the most part, i'm pretty comfortable with that.

Okay, now i am more of a practical person and i realize that a lot of times it doesn't get that low uh. So your question is 700 to 900 microns close enough. If you want to go home, i mean sure you know have i done systems where i pulled it to just a thousand microns before and let it go yeah i have okay. Have i done systems where i couldn't get it below 500 or below a thousand microns yeah? I have and i've i've let them run so it really depends on your judgment, call when you're in the field um and basically you know what's acceptable.

Do you understand what happens if you don't pull a proper evacuation, there's also the question of what is the what what is happening in your system when you're the the decay test is rising really high when the microns are rising really high, do you actually have a Leak or do you have moisture in the system or non-condensables in the system? Who knows okay, so understanding the things that can happen? If you don't pull a proper evacuation and there's moisture left in the system or non-condensables left in the system, then you're potentially going to have some issues when the system's running okay. But you can't always be perfect, especially the supermarket. Guys know this much better than i, but even i when i'm doing a beer walk-in, you know and it's been down all day and i have to start the system up. I mean.

Sometimes you can't pull the perfect evacuation. You just got to get it up and running because they need to sell their beer and they're losing money. There's an acceptable. You know, hey perfection, isn't achievable in certain situations.

So the answer to your question is: it really depends on your judgment call and you have to make that out in the field and know hey. Is this good enough, but you also have to know when you're, just cutting corners and you're just trying to go home faster, there's, nothing worse than someone cutting corners, and here comes the coke nose, guys all right all right. Let's move on to the next question! Um! I'm gon na get to my list of things. Uh have.

I ever had anything actually blow up. While i was working, yeah yeah, i have actually um. I don't know that i've quite got it on camera, though um. No, i don't.

I try to capture it, especially now. You know in the very beginning of doing my videos i was i tried to edit really hard and i realized that i started getting these comments from people saying. Oh, my gosh you're perfect. I'm not perfect guys.

I screw stuff up all the time so um you know i i try to make a point to show my mistakes, even more so than i ever have now to try to let people know that i'm just a normal guy, i'm not anything special. I just basically have turned on a camera and started recording myself. I know there's many other tech techs out there much better than i that just haven't gotten the exposure or the ability to turn on a camera and start recording. Okay.

I want to address this right now too. We got quite a few people in here right now. Do me a favor hit the like button. It really does help the channel okay.

So please smash that like button guys, because my screen says we got 442 people in here and 165 likes. So please step out, even if you got to back out of the chat for a second hit that thumbs up button, even if you're on mobile, you can do it and help the stream out. Okay, it really does help. So last week's live stream uh there was something that was brought up um.

I believe it was joe shearer that brought up was a commenter. Joe shearer has a youtube channel too i've communicated with him. I actually met him at ahr. Show um joe shearer brought up something because he said i said something incorrectly and we actually addressed it on the hvac overtime channel over the weekend on friday he was absolutely correct.

I was incorrect in something that i said on my video. So last week someone had asked me a question about why i have single phase or two pull contactors on three phase systems, and i had said for two reasons i said number one to save money but number two, because they use it as a crankcase heater. Now i was incorrect about the crankcase heater so guys, i'm telling you guys, i'm not perfect on everything. Okay, i've heard that so many years in my career and even joe and there was um.

Who else was it? It was someone else that was. Was it total tech, another another tech and joe were kind of going back and forth? I can't remember i'm sorry if i'm butchering, whoever else it was that was telling me, but i was incorrect in saying that it was using it as a crankcase heater. Now there is a certain instance, and i wish i had a schematic. I could pull up in front of you guys where, on a residential system they will use.

You have 208 volts or 240 volts single phase coming into the residential system. But if you notice on some of them, the contactor is only disconnecting one pole now in some situations on some of those residential systems. My understanding is is that that can still act as a crank case heater and what it does is it uses a capacitor runs back through, but on my three phase systems, i made an assumption thinking that it was acting as a crankcase heater when they were using The two-pole contactor on the three-phase system, because when they do a two pull on a three-phase system, one leg is always going to the compressor. One leg is going to every three-phase device in that system and it's always energized and then there's nothing else going through.

But i was incorrect, guys, okay, so i do not know everything. I make mistakes all the time um and i was looking at a schematic because they brought it to. My attention actually was brought up in the overtime thing and then i got like totally distracted and started looking at schematics for carrier package units and as i was looking at the schematic, i'm like this. No, this absolutely does not work as a crank case, heater uh.

So the the the carrier's ones that i'm working on basically the two pull contactors are simply just there to save money. They're not there to to act as a crankcase heater. Now, in some situations there is a configuration where that might work, especially on the residential ones, but it does not apply to the three-phase units. Okay, um.

What is my, let me see: crankcase heater keeps the liquid refrigerant okay. So let me see what i'm missing in here um. What am i missing? In a pinch, have i ever had to pull a vacuum with my mouth, just asking thanks no ghost face, i've never had to pull a vacuum with my mouth um. Let me see what else uh i still learning new things in the field: yeah.

Definitely i'm still learning new stuff, all the time, technology's changing every single day, so all new stuff. Coming in what am i missing in here uh in a pin? No, i already answered that one and let me get down here what do crank case heaters do so crank case heaters are simply there to keep the liquid refrigerant from migrating, basically into the compressor on startup. If we have a lot of liquid refrigerant in the compressor, we can actually wash the oil out of the compressor, so the crankcase heater is there to keep the oil and the compressor warm. So that way, there's not a big pressure differential and the liquid refrigerant doesn't migrate to the compressor.

What is my process for finding difficult leaks, that's taking longer than normal, mr green. So, first off you start with the basic steps you look at the evaporator. Look at the expansion valve look at the condenser return bands. Look for any visual signs of oil.

The next thing that i'm going to do is maybe bump the system pressures up. So there's a couple different ways. You can do that if you're working on a heat pump, you can actually run it in heating mode. So that way, the evaporator or the indoor coil builds up pressure then turn the system off when you get it nice and hot, and do a leak check on the evaporator a lot of times on our equipment.

The leaks are in the evaporators okay, because the evaporators are typically exposed to the indoor air that usually has contaminants different things like that in a residential home, you've got all kinds of different cleaners and different things and chemicals that are in the air. You know contaminating the coil causing corrosive stuff and eating it away. So if you have a heat pump turn the system on in heating build up the pressure in the system oftentimes as you get the pressures higher it's easier to find refrigerant leaks. If you can't do it that way, uh you can do the same thing like on a condenser.

You can build the pressure up if you're working on a refrigeration system and uh you've got a low, temp downstairs evaporators, and then you have, you know uh the condenser up on the roof. It can be a little difficult to build up the pressure in the evaporator.
