Ah, it's time to chill out and get ready for a mediocre q, a live stream if you're old enough grab yourself your favorite adult beverage and if you're not stick with apple juice, put your feet up and relax. If you have any questions, feel free to ask them in the chat and now, let's queue up the intro music yo, how you guys doing this evening. Hopefully everything is going well um. It's still hot here in socal we're kind of having this weird like intro to fall, but it does this to us every year where the nights start getting cool ish like 83 at night time.

You know and then we still have 100 degree days um. It's kind of it's kind of misleading, because the way the weather works here in southern california is we have like crazy heat waves for two months where we get. You know in excess of 100 degrees for two months straight, and then it falls off the map. But then we really don't start getting cold right into our winter until november.

So now what we're in this stage is we'll have these really hot days and then we'll have like a cool down so for this week i think, like the highs in my area are um 98.99 all week and then on saturday, it's supposed to hit 109 again And then next week it's going to fall down again um the nighttime's hitting like in the 80s, and then we go into this weird um, where we start getting really cool nights coming at the end of september, beginning of october. But then we still have hot days now we don't really hit our winter season if you call it winter right, because we don't know what cold is here in california. Our winters are typically like, on average, 55 degrees right. So, that's that's why everybody flocks to this horrendous, ridiculously crazy state is because of the weather.

Essentially, so our winters are 50 55.. I mean our ultimate low in my area we might hit, like you know, a couple nights where we hit like in the 30s, but that's it and then you know we really don't get any colder than in the 30s. So but we don't hit that cold. You know into the 50s until the beginning of november-ish.

Usually we still have what we call our uh our annual wind event. We call it the santa ana winds in southern california. They call them like the diablo winds up in northern california, so those still have to come and then once the santa ana winds come like towards the end of september. That's our true fire season was when it starts and then and then it'll start to get cool.

Ish, but we're still in this weird stage right now and what's going to happen here in a couple weeks, we're going to start getting cooler nights where the temperature is going to drop to the 70s and then we're going to get these nuisance service calls on the Refrigeration equipment of my equipment works during the day, but in the evening and in the early morning it doesn't work and what's happened because you know we have such extreme highs through the summer is there's refrigerant leaks in the equipment, so we have refrigerant leaks. All the time right, there's always leaks in refrigeration equipment naca. Thank you very much for that super chat connor. I really appreciate it, but um so we'll get those those nusense service calls where you'll go out there at noon and it'll be working fine down to temperature.

The walk-in and everything's good well, what it is is the unit has refrigerant leaks and at nighttime when the temperature drops the head pressure, control, valves, bypass and there's not enough refrigerant to flood the condenser. So then it starves, the evaporator and the temperatures go up. So you get those weird nuisance calls. So keep that in mind.

If you ever get those walking calls like that's a dead giveaway in october in california, if you get the um, it doesn't work in the morning, but it works in the afternoon. Calls because it warms up in the afternoon and the head pressure, control valve will shut off and stop bypassing uh, and you know then, in the evening when it cools down, it starts to flood, and you know all those crazy things. So we have that it's it's pretty typical. It comes every year and then you can always um know when our winter's coming, because it never gets cold like really cold until after we get the santa ana winds and the santa ana winds are crazy, because it's just a sporadic wind event that we get and It usually goes for a couple weeks and we get sometimes um.

You know 50, 60, 70 mile an hour gusts, not consistent, but just gusts in my area, and then you know just all the trees like, we all have to make sure that we trim our trees and everything, and then it gets imperative on the rooftops that we Um we bolt all our equipment uh panels on basically, so you know we make sure that come in the next couple weeks, every restaurant we go to. We tell every tech. There has to be at least two to four screws in every single panel, because if you just have one screw, the wind will rip that off. I had a restaurant many years ago where it was an el torito.

I don't do their work anymore, so i can say it an el torito, mexican, restaurant and uh. We got a call that they had multiple air conditioners, not working and we got there and what happened. Was we had a crazy santa ana wind event like crazy, crazy and uh? The swamp coolers like the whole roof was destroyed. There was panels on the freeway they're they're next to a freeway.

They had a parking lot and then the freeway we had uh. You know condenser coil covers and different things like that or condenser compressor panels and stuff on the freeway. We had to literally go drive on the freeway pull off the on-ramp run over through the bushes. The ivy grab all the panels.

It was a nightmare, but they had swamp coolers that blew off of the platforms and they were being held on by the electrical whips um yeah it was that was a crazy wind event, good gosh. That must have been it's funny. I remember that that must have been 20 years ago. I uh maybe 17 years ago see.

The thing is is that i've officially been doing this for like 17 18 years, but i grew up in the trade, so i can remember stuff from when i was a kid too um, it's nuts yeah, so we've got that crazy, crazy winter, hey um! I hope you guys are doing well. Uh, we've got all kinds of cool stuff to talk about um. I definitely want to address the chat. You guys get your questions ready.

Remember that the questions you put them in caps lock. It helps me to get to them. If you guys could really do me a favor and hit the thumbs up button on the stream, it definitely helps the channel. Okay, please please do that um, but yeah throw your questions in caps lock.

If i don't get to them, just put them again and uh. I will uh um try to get to it, okay, so uh. I want to start off by mentioning before i forget. Some buddies of mine started a new podcast: okay um.

It's called hvac radio uh, my two buddies uh reuben, macias, he's rookie, refrigeration and ulysses palacios. Um, i believe i pronounced your name right. Hopefully i did ulysses and i didn't butcher it. Uh ulysses had a youtube channel.

He still has a youtube channel, but he hasn't posted in a long time, but a lot of the people that have been on youtube for a while. You guys know who ulysses is he's the dude that was cutting open compressors for years, um them and two other guys. Forgive me, i personally don't know the other two gentlemen, but i believe majority of them work for the same refrigeration company, but i heard their first episode today. It's called hvac radio, i'm gon na post a link in the chat right now for spotify, but you guys go check it out.

Um they did their first one with their introduction and uh. Here's a link right now. You guys go subscribe to their podcast um. These are, i know, ulysses and reuben, both really cool dudes uh.

I've inter i've personally met rube and i've only interacted with ulysses on the internet, but seems like a cool, dude and ruben has told me, he's a cool dude, so go check out their podcast subscribe to it, guys, um and uh tell them. I sent you so. Okay and hopefully uh uh, i will be on there soon. I think that that's what they had said they wanted to get me on so i'll be a guest.

I'm sure at some point in time on this thing, but seems like it'll, be a cool podcast. I think they're going to try to talk about refrigeration and stuff so check it out. It should be a good one. Um lots of things to talk about in here.

Let me get to the chat real, quick uh did i get the stratus or the h10? I actually do not have either the stratus or the h10. I have used the dtec select for many years that has been my go-to leak detector, i'm considering purchasing the stratus. I've heard a lot of people. I've heard mixed results, good and bad, but they also, i believe, on rick's i caught the tale.

Just the beginning of rick's uh live stream where he was talking about the new leak detector, so he happened to have the stratus, and then he also had to step down from the stratus, which my understanding is, the replacement for the detex select. So essentially, it's the stratus without the parts per million counter on it um i have always been a dtek fan. I've used the detex select, i'm not kidding with you for more than 10 years now, not the same one. I've replaced it a couple times or passed.

It down to other people, but the detect select, has been my go-to. So let me see what else we got in here. Have i ever thought about the redfish meter to use with measure quick, you've started with using measure quick but haven't purchased the redfish meter so matt? I actually have the redfish meter um. I don't use it very often.

It is a very capable meter. It does a really good job, it has all sorts of great features: um, i'm just a fan of the field piece meters and the the the the the feel of the field piece in your hands, the way that it fits in my bag um, nothing wrong with The redfish meter, but it's a bench, meter. Okay, it's a meter that you use. You know um.

Actually, no, it's not a bench meter, i'm sorry! I apologize duh. They have two meters for the redfish, the id the idvm-550 is the clamp meter and then they have a bench meter. So i have the clamp meter um, but i just am very partial to the field piece meters. They've done really well for me, but i do have the redfish.

It is a cool meter. It is the only one that you can accurately use with, or no it is the only one that you can use with measure quick at this point in time. Um and uh, but it's a good one, so i definitely check it out. I just like the field piece because of the way that it fits in my bag and the phase rotation tester on the field.

Piece meter is like what really sells me on it. Uh, the sc640, i think, is the one that i use. I don't know the name of it. I think it's the 640, the it's the new clamp meter, the small clamp meter and then the sc680 is the new loaded, clamp meter, the big one um both of them.

The really cool thing is both of them have phase rotation. So but yes, i do the the the redfish meter is a nice meter. I do have it so i'm not going to say anything bad about it. It's it's a great quality meter, so um, let's see what else ian.

I do see your question right here and i saw you ask it a few minutes ago: how does a heat pump work so it you really need a visual to understand completely how a heat pump works but in a nutshell, the easiest way to explain a heat Pump first off, you have to understand a basic air conditioning system on a basic air conditioning system. You have a compressor that compresses refrigerant it drives it through a condenser. The condenser is a giant heat exchanger. The heat exchanger changes the state of the refrigerant, so it takes outdoor ambient air.

That's at the lower temperature, blows it across the refrigeration tubes and actually changes the state of the refrigerant to a liquid refrigerant coming out of the condenser. When that happens, it's a phase. Change you now push the refrigerant into a metering device that um, basically uh, think of a metering device. The easiest way to understand a metering device is, if you have a spray nozzle on your hose and you spray it and the water just mists out: okay, um, the easiest way, the simplest way to explain an expansion valve is essentially that it's it's a metering device That flashes, the refrigerant okay into tiny, liquid and vapor particles that go into the evaporator and the heat exchange happens there too.

You have indoor air running across the evaporator, it absorbs the heat. Okay, so therefore it cools the air running across the evaporator. Then you cool the space. Okay, then that refrigerant goes back to the compressor, gets compressed again.

Okay and vice versa, or in the cycle continues now, when you have a heat pump, what it actually does is it typically has a three-way valve or a reversing valve. Okay and it changes the flow of refrigerant and what it does is it takes the indoor evaporator and moves it outside okay. So now the heat exchange process is just reversed. The indoor coil becomes your condenser coil, okay and it discharges the heat or the the high temperature high pressure.

Superheated vapor is pumped to the indoor coil now right and the air runs across it and it absorbs the heat and heats up the space and then now the cold, refrigerant. Okay, because the cycle is reversed, the expansion valve or the metering device pushes the refrigerant out to the outdoor coil now and the outdoor air is actually cooled. Okay, so all it does is reverse the process. So in an air conditioner you take indoor air, okay, it is absorbed into the refrigerant, it pulls the heat out of it and cools the air on a heat pump.

It reverses that cycle and takes the the the indoor air and heats it up. Okay, now again, the reason why i said in the very beginning, you really need to see us an animation, essentially so go check out my buddy brian orr over at hvacr school or hvac school um. It's hvacrschool.com is his website, but hvac squad on facebook he's got a podcast and stuff and i'm pretty confident he's going to have some sort of a animation of some sort on his website. That shows the process of a heat pump and it'll help you to kind of understand, but essentially it's an air conditioner and via a three-way valve.

You just change the flow of refrigerant to where the outdoor coil now cools the air. The indoor coil now heats the air okay, so that's the general in a nutshell, explanation for a heat pump. So hopefully that helps you a little bit bud all right. Let's see what else we got in here: um yeah, a reverse cycle - air conditioner, big pond cable guy, says that and that's exactly what it is.

It's a reverse cycle. All it does is swap the coils. So your outdoor coil becomes your evaporator. Your indoor coil becomes your condenser and then in the refrigeration or the cooling cycle, the indoor coil becomes the evaporator.

The outdoor coil becomes the condenser, so all you're doing is changing the flow of refrigerant. Okay, it's a pretty uh smart way to do something right, um! It's pretty genius when you really think about it: okay, because you're using the same energy, so interesting, okay, um, uh, connor crews asked what low loss fittings have. I had the best experience with uh yeah. I don't use low loss fittings.

Okay, i use ball valves. I i guess in a way that is a low loss fitting, so i've always used a ball valve that has a six inch hose coming off of it. I prefer that style, because you get a better flow of refrigerant through it when you're charging when you're again. It's not perfect, you shouldn't do this all the time, but when you're evacuating through your manifold gauge set, i prefer to have a low loss fitting okay, i mean i'm sorry a ball valve okay, but i try not to vacuum through my manifold as much as possible.

I try to use a uh, the true blue hoses as much as possible, but every once and well. You know you got to do what you got to do so, but i've always used ball valves. I've had very good luck with them. Uh.

Never myself been a fan of the low loss fittings, so um, let's see what else uh yeah exactly all right, um all right. I got a couple things: uh watch with joe he'll steal my microphone yeah all right. Let me see uh what we got in here. Hey uh dallas, how you doing bud dizzy, dallas is in here too.

Dallas has a youtube channel check it out guys click on his name, and i think you can go to his youtube channel on there. So, what's my process after doing a leak search and not finding any leaks, so it really depends uh. How low was the system on refrigerant? Are we talking ounces, or are we talking pounds of refrigerant, okay, um? If i'm working on a refrigeration system like, for instance today, i uh before i had this live stream, i got in here a little bit late and i had a service call on a walk-in cooler. I arrived on site i'll, make a video of it eventually, but i arrived on site and found that the system was low on refrigerant.

The walking cooler was a little bit warm and i went inside the or went up to the roof checked out the sight glass. The sight glass was flashing. My evaporator coil was clear. It wasn't iced up, we had all evaporative fan motors running, so it was a dead giveaway of low on refrigerant.

So i went and put my service gauges on. It confirmed that it was low on refrigerant and i proceeded to add refrigerant before i found a leak okay, so i added refrigerant and i cleared up the sight glass. Then the unit had a head pressure control valve. So i had to add a couple extra pounds of refrigerant, so i did so um and then once i was done with that, i went and weighed the cylinder and i found out that i had added five pounds.

I believe it was five pounds of refrigerant to the system, so five pounds of refrigerant is a pretty big char, uh loss of refrigerant. So i knew that there was a refrigerant leak, especially when the system probably only takes 12 pounds of gas okay. So i knew there was a refrigerant leak now had i only had to add, like you know, half a pound i wouldn't be as concerned as having to add five pounds. So in that case, i did a leak search on it and i actually found a leak, but i didn't stop at just that leak, see that's really important when you're doing a leak search.

I this is what i tell my guys too. You don't just stop at the first leak you find because we can have multiple leaks. Now, it's one thing: if the leak is so big, you can't find anything else. Okay, you've got to fix that one first, but just because you come across a leak, don't stop there keep checking the rest of the system.

Okay. So how do i know when to keep looking, and what do i do if i can't find a leak? Well, in a situation like this, i had to add five pounds of gas. If i couldn't find a leak, i know it's there. Five pounds of gas doesn't disappear.

Okay, if we're talking ounces of refrigerant, it could be from people putting their gauges on and off. I'm not gon na sweat that one too much but with five pounds, there's a leak so had i not been able to find the leak okay on a cracked discharge line. What i would have done is, i would have um equalized the system pressures. Okay, so i would have uh let the system run without a condenser fan motor for a few minutes got the head pressure, nice and high.

Before it shut off on high pressure, then i would have shut the disconnect off or the breaker, and i would have opened up both sides of my gauges. Let the high pressure go into the low side and let the pressures equalize out into the high and the low side. So that way, i got higher pressures on both sides of the system and i would have done a leak search. If that didn't result or find me the refrigerant leak, then what i would have done is, i would have recovered the charge pressurize the system with refrigerant and nitrogen.

I would have put about a pound of refrigerant in there and then just jam nitrogen. On top of it to about 150 200 psi, depending on the the system test, pressures, okay and i would have went looking for a leak and i slowly would be increasing the nitrogen pressure until i found said leak. Now, you got to be really careful about that. If you have sensitive components in the system, such as pressure transducers electronic expansion valves, because from experience, i've made some videos about it, i've screwed up systems by over pressurizing with nitrogen, doing a leak test on the system.

Screwed, the um, the pressure transducer off, made it all cattywompus and it didn't work right. Okay, so be very cautious with that. That's why they have minimum and maximum test pressures on evaporators, usually okay, so uh. If i don't have any of those sensitive components, then i'm gon na keep adding nitrogen slowly by 25 pound increments.

Until i either make the leak or find the leak. Okay, obviously not going over like 400 psi. Okay, be very careful about that. But the idea is: is that again, being very careful, it's last ditch resort.

You don't ever want to go over the test pressures on the system, but sometimes you just got to find the leak, and you can't you know, wait um. So that's what i would have done and that's my process of finding a leak that i can't find now once i find the leak, then repair, it evacuate the system recharge it all that good stuff. Okay, let's see what else we got in here. What am i missing uh? What can cause a compressor to short to ground and trip the breaker? What can cause a compressor? Well, i would say, in my opinion, the common things that cause a compressor to short to ground are moisture in the system causing a possible acidic condition, uh adam.

Thank you very much for that super chat, dude that what the hell man that's a killer. Super chat. Dude um. Thank you very much man.

I really appreciate it. Okay, dude you're, killing it um anyways. You guys don't have to do these super chats, but thank you very much. Okay um, especially you adam good gosh, maybe maybe lose my train of thought.

Good. Good super chat there adam. What was i even talking about now? I don't know you made me: lose it um, oh compressed or short to ground, so moisture in the system and uh overheated conditions in the system. So let's say you have loss of oil in the system running without oil, although lots of oil would probably cause a mechanical failure before it would cause a direct short to ground.

Most of the time, i would say would be a a insulation issue where the windings ended up, shorting out and usually that's caused by moisture and or an acidic condition. So if you have a short to ground, it's really important to understand that you don't want to just change that compressor. Okay, what you do you let the customer know i can't diagnose what caused the ground until after i change the compressor, so the customer has to understand they're going to have an eight hour repair time change in a compressor. They're gon na have all that money in that and then after you're all done.

Typically, what i do is i let it run for a day. I come back test the system for acid, okay and then i'm going to uh diagnose the system check. The expansion valve see, if we're having oil return issues. Another really important thing anytime, you're doing a compressor change and i'm guilty of not doing this enough is what you want to do when you get the old compressor out.

Is you want to pour it all? Pour it out and measure the oil okay, if that system, if that compressor, is severely low on oil? That means that that oil is in your system now, unless you have a giant leak, and you have oil everywhere. Okay, that oil is going to make it back to the new compressor and that oil can be contaminated. Now a lot of people ask me all the time, i'm personally not a fan of using any additives in the system as far as acid aways or anything like that. Okay, that's my personal preference.

Okay! I don't use any purges like r11 flush or anything like that. I used to okay and i i honestly can say that i never have seen a bad result of using rx11 flush. But i have recently changed my waves within the last couple years and decided that i really don't want to use that stuff anymore, because i've kind of gotten into the whole mind frame of i want to keep what's in the system and what's supposed to be in The system - and i don't really want to be adding additives to the system. Okay, um.

It really goes down to a podcast that i heard with john pasterello and brian orr, where john was basically saying how he had analyzed different things and he took like um. You know some of the acid away products or whatever brand makes you know an acid neutralizer. He took some of those and he just like broke them down, and he was saying like these really aren't anything and they're not really supposed to be in the system, and that really got me to thinking about it. And you know most manufacturers really don't want any of those additives in the system.

So when i have a grounded compressor as far as my diagnostics go or i mean as far as my repair process, what i do is i pull the compressor out and i start cutting components out of the system. Another thing i will tell you is that if i have a grounded compressor automatically included in my compressor price, is a new expansion valve just flat out okay and a suction line? High acid filter dryer like the sporelin hh, suction line, filter dryer and a sporlan hh liquid line, filter dryer. If you can go with a flare on the liquid line, filter dryer, so that we can go in and swap it out a couple times. If you need be, but sometimes you can't okay, so i'm always gon na add an expansion valve to the mix usually too, because there's no sense in changing that really expensive compressor and not changing a 60 expansion valve while you're in there and you have all the Refrigerant out, and that very well could be the cause of it.

That's my personal preference when i'm doing that, okay, so the things that can cause it in my opinion, are moisture in the system. I'm sure there's something else that i'm not thinking of, but those are usually the normal causes. So all right, let's see what else we got in here. What am i missing? Um uh: let's see what we got in here, uh eric m's in here eric has a youtube.

Channel too. You guys got ta go check that out. Eric has lots of cool videos. He's been posting for a long time eric.

How long have you been on youtube? I want to say that eric is one of the one of the first guys again that i started watching um like, for instance, when ulysses was making videos again guys um, i plugged ulysses new podcast ulysses and uh reuben macias, and it's not just their podcast. There's two other guys on there too, but i just personally don't know the other guy's names as much as i know, ulysses and uh ruben. So it's called hvac radio podcast, i'm gon na post a link in here again guys go subscribe. This is the spotify link.

Go check it out: okay, um, but yeah. I see eric iman here. I don't know how long you've been on youtube. Eric it's been like years right, um, all right, let's see what else if you have uh so prime time's saying if he has a grounded compressor depending on size, he'll install a suction, exchangeable core and that's a good idea: suction uh, a normal hh suction line, dryer.

Also, a normal hh liquid liner yeah, i usually don't work on the systems that i can put in the core, the removable cores i wish i did because those removable cores are awesome. It makes changing the dryer so much easier, especially if you ball valve it put two ball valves on each side of it boom knock that out real quick, um uh eric m. I think you're asking me if i have converted r22 to 404 and had high superheat txv was replaced. No, i i can't say i don't think i've ever taken an existing system from r22 to 404 um.

I'm trying to think if i've done that, not without changing out the evaporator, i think i usually on the most of that i've been lucky enough that if i've had to convert from that i've done that you know eric, though the only thing i would ask you Is did you get to the nozzle because that could be playing with your superheat a little bit? I don't know about that, but if you know the nozzle, that's between the txv for those of you, i know eric knows what it is, but for those of you that don't know on uh walking, cooler, evaporators and things like that, the multi-circuited evaporators they'll typically have A nozzle it looks like a fixed orifice metering device or a piston, and it goes in between the expansion valve and the distributor, and it just allows for more even flow across the evaporator, but eric no. I can't say that i've ever had uh done that off. The top of my head that i've ever done a swat or a conversion, basically um. We can't even use 404 here in california, anymore um.

We haven't been able to use 404 for major system retrofits for a year and a half. Now we have to go to a new alternative and the new alternative lately has been r448a, which i actually was working on in our 448a compressor today. The problem with r448a very similar to r22 is when you get to the lower temperatures you, you tend to run really high uh discharge line. Temps, obviously run lower pressures, but really high discharge line temps.

So uh you have some real issues with that. That can be a pain for sure. Let's see what else uh i'm missing comments in here right now, so hopefully i'm not missing too much. Let's see what we got in here, um.

Let me see okay, so i didn't miss anything there. Yeah. If i pass, you guys comments, forgive me, okay, what drill do i use if not milwaukee, why not the wide variety of tools um, if not milwaukee, so i use milwaukee and dewalt so um. The main reason why i use milwaukee and dewalt is because i bought a dewalt set 10 years ago and it works fine, so there's no reason to replace it.

Now i did have a dewalt um screw gun like a 12 volt drill and it went out basically so i decided to replace it and i ended up going with the milwaukee m12 and i've been using that for a while. So i have the milwaukee m12. I've had actually started intermingling a lot of my tools, so i have a lot of milwaukee tools now and a lot of dewalt tools. Um i like them both.

I have nothing bad to say about them. I mean they're good tools either way. So, let's see what else we got in here: um yeah, there's, ralph, dallas fan yeah, so r448a is higher discharge line, temps, um but lower than r22 for sure, but yeah i tend to run higher discharge line temps on them. If you're uh, most of the r448a equipment out there, that you're going to come with, is actually it's pretty much a requirement if you're going to go to low temp that you have to have a liquid injection valve or a trev temperature responsive expansion valve.

So this is a dtc valve for a copeland compressor. It goes via a rotolock fitting, and essentially this is an expansion valve guys. That's all that this is okay. This is a temperature responsive expansion valve pushes in the head of the compressor right there, and when the head of the compressor gets above a certain temperature, it opens uh the basically just like an expansion valve it pushes down.

I think i can show you guys here. Real quick because i've got this one all opened up, let's see what else we got in here, so it has a little piston inside here that pushes down on those two pins, just like an expansion valve and it opens and closes this guy and it works just Like an expansion valve to cool the head of the compressor off, if you don't have a copeland scroll compressor, you can actually use a trev or a temperature. Responsive expansion valve spoiling also makes those um. I can't remember the part number on the spoiling valve, but anyways you can add those to the system and that will help when you have those higher discharge line, temperatures to try to cool off the compressor a little bit there um really, oh, so i world leader, Said he just got my hat in the middle.

Thank you for reminding me about that so um, those of you guys that have been uh purchasing hats and different things like that. I was getting a little behind, but i've been trying to keep up on the merch. I really appreciate your support. It is coming.

I have another, you guys can maybe see the tail end of it. I've got another little stack of boxes right here that the postal service is going to come pick up tomorrow, really really appreciate you guys on that. Okay, i am running low on my hat stock right now, but i do i got the confirmation today that the new ones are in uh in route, basically they're already being shipped to me. So i've got a bunch of small mediums and a bunch of large extra larges that'll, be here probably within late this week early next week.

So if i am out of stock by the time, you guys look they'll be back in stock and i should be pretty good on shirts right now. I think i ran out of some of the sizes, but i'm pretty sure it's still good to go, and i think i mentioned this on the last live stream um. I will have uh i'm working right now. I'm waiting on the samples, i believe, i'm going to get the samples next week for beanies.

I have two different styles of beanies that i have. I had them make and sample. So those should be here - maybe next week, we'll see but though they won't be in stock. Yet that's just the samples once i approve the samples and make sure everything's good, then i'll order, a full production order.

So i'm hoping that by the beginning of october ish i should have beanies in stock. You know so, let's see how that works. Okay, but i really appreciate your guys support so um, let's see what else we got in here. What am i missing? I see so much stuff that it comes in uh, hvac grandpa.

How come the supplier in california still 404 systems have forced them to sell us, our okay. So how come suppliers in california hvac grandpa? I don't. I don't quite understand your question, but here in california, 404 a is being phased out and it's actually technically illegal to use on new installations and or major system retrofits. Okay, if you talk to the california air resources board, they'll tell you that a major system retrofit is an expansion valve change, an evaporator change, a compressor change or a condenser change, so essentially, okay, pretty much almost anything now you're allowed to do leak, repairs now.

Okay, does every one of my customers go for that heck? No okay, but we try as hard as we can that whenever we replace equipment, i definitely demand that we go with r448a. Okay, so r448a is the new refrigerant that i have chosen to use and i have my equipment sized appropriately for 448a and we've been working on that hvac grandpa. I don't quite understand the context of your question uh, but as far as the supply houses go up, maybe i'm answering in a roundabout way. As far as the supply houses go, it's not them forcing 448a on us.

It's the government basically saying that we can't use 404 anymore. Okay, so, what's actually happening is the supply manufacturers, okay or the manufacturers of equipment are having to redesign their designs, basically make them more energy efficient, make them capable of working with these new refrigerants. Now, a little secret is that the condensing unit that you buy can work with 448 a 404 a 22. It just has polyester oil in it.

It can work with any one of those refrigerants okay. So, even though the condensed unit says 448a on it, it's still capable of working with those other refrigerants the evaporators. However, it goes a little bit more. You can definitely make evaporators work too, but if they're pre-built you've got to make sure that you, the nozzles change the expansion valves change, if you're doing it correctly and when i do new installs, i really don't try to utilize any of the old expansion valves or Anything i'm doing um expansion valve changeouts, changing the nozzle um and doing all that stuff.

Okay. So hopefully i answered your question there. Hvac grandpa uh have i ever heard of or used r600 no. I have not um and let me do something here: real, quick uh.

Let me go to gmail and get an email address, real quick hold on just one second um. Let me go and hold on just one sec. I see that my buddy ralph in here my buddy ralph works for honeywell refrigerants. Okay.

Ralph has always been very willing to help me out with any uh refrigerant conversion issues or anything like that, and actually ralph has really helped me out with a lot of the new legal requirements and different things like that. So if any of you guys have questions about conversions, what refrigerants are best and all that different stuff, i highly encourage you guys to get a hold of ralph, i'm going to go ahead and paste his email address in the chat right now. Okay, now, let's clarify something because i had someone email me today about a honeywell thermostat. I forgive me, i don't know your name, but you emailed me today and you said: hey: what's your buddy's name that works for honeywell, okay, honeywell thermostats are now um, honeywell, isn't making those anymore a company called residio, i believe, is making them so that wouldn't be Ralph ralph just deals with the refrigerants okay um, but you can email, ralph and i'm sure he'll tell you the whole spiel about it and stuff like that, all right, let's see what else we got in here um.

Let me see what i'm missing here. I'm looking! These these comments go by so fast yeah. Exactly eric eric m is saying: the us government is the world's largest polluter, but they tell you not to use 404.. It's a whole welcome to yeah anywhere.

So, let's not even go there. It's a nightmare, so uh all right, um. Let me see what else we got in here. Yeah.

Thank you, ralph ralph's always willing to help out in here. So that's why i always push his name out there. If you guys have any questions just reach out to him, okay, just to make it clear, i got no affiliation with ralph ralph's just been a really cool. Dude has always been very open to answer my questions, so that's why i, whenever people ask me refrigerant, related questions, i always push them towards ralph, because he can usually guide you in the right direction.

So what do i think about press fittings like zoom lock for refrigeration, um, okay, great question, so i have been on the fence for a very long time about press fittings. Okay, i am that old school guy that had that old school mentality. For the longest time where i thought i don't want to use a press fitting, that just seems silly when i can braise something okay, i have been really changing my thought process with that lately, especially when the press fittings have gotten very popular now, full disclosure. I have never used any press fittings out there.

I've never used the zoom lock. I've never used um zoom, lock max the new fitting, never used any of them. Okay, but i am going to okay. Now, i'm not saying i'm going to start using them on every single job, but there is certain jobs where i've realized that they have been.

They would be a very good help to me. Okay, so it is something that i'm looking into. I have been looking into it for a very long time and for those of you that don't know, there's actually a little change with the zoom lock with spoiling right now, and they actually have a new fitting called the zoom lock max. The fitting does change you.

Do need a different head um, but i am i'm in talks with sporland to get myself a set of heads. So that way, i can start uh testing it out, because i have a couple different jobs where i think it would actually benefit me to try the zoom lock max and see where it goes with that okay, um there's also, you know the thing that kind of Held me back on that was like. I was just very stubborn when it came to those fittings and different things like that, but i mean it's pretty much been said. There's so many people out there that have been advocates for those press fittings.

Now, i'm not saying i'm going to use them on every single job, but there's certain things like when i used to work for a government facility, not a government facility, but a restaurant. That was in a government facility, and it was such a nightmare to to be able to braze in a liquid line dryer. They would literally make me come in on a saturday. They would evacuate the building it was.

It was so silly to change a liquid line. Filter, i'm not kidding with you, they would make sure that nobody's in the building like government buildings are insane. So when you come into the some of those institutional work um and they have uh really strict fire permits and fire conditions uh, you know that's where a press fitting would be very beneficial for sure. Okay, so you know had i had something like the zoom lock max back, then it really would have helped me because they even make zoom lock max dryers.

Okay, so you wouldn't even have to braze in the dryer um. That would have been very beneficial with some of those uh repairs that i did at that particular facility. Now i don't do work for that facility anymore, but um that would have been really cool to be able to use that back then, because it would have saved me so many headaches. I remember some of them.

Sometimes they were like the first time. They told me this, i told them. I had to um schedule to come in to change a you know, fix a leak and change a dryer, and they were like all right and they handed me this pamphlet of stuff to fill out and i started reading through it and they're like you have to Have a fire watch and it was this - was probably like 15 years ago and the first time i read it, i'm like what the hell you got. Ta have a fire watch.

What is this? You know - and it seems so silly, but that was my introduction to institutional work in a government building and it was like wow that blew my mind, but that there's a lot of dudes out there that that work in that kind of stuff. All the time and those press fittings, they really do help them because they don't have to pull fire permits and they don't have to you know, have fire watches like literally. Some of these places will make you have someone stand there for six to eight hours after 24 hours, whatever it is to make sure that there's not a fire when, when you're all done and you're cooled and the system's running, there's no fire you're standing. But it's just politics: they make you do that stuff.

So one of those press fittings would be awesome in that situation for sure um, let's see what else we has. What do we got in here? Hmm, all right, so i got a couple things. I'm gon na go ahead and get to my list of things to talk about. Have i ever done any work in a prison? If so, would i charge different rates actually daniel? I'm gon na answer that question right now: um, oh joe smith, how about making a flare versus zoom lock? I mean i'm sure i could do it.

I'm sure that we can do all kinds of experiments and different things. Um so have i done work in a prison? Yes and no okay. I personally have never done work in a prison, but i did do a quote one time in a prison so uh the process went like this um. They called us via a supply house.

They, the the local prison, uh chino women's prison here in southern california. They called my supply house and they said hey. We need a couple bids. Do you have any contractors that can help to bid on this? It was to replace a walk-in door on a walk-in freezer, so like a bolt-on, walk-in door, so my local supply house reached out to me.

They said hey, they want some bids, so we had to go through this process. I had to be vetted so they needed all my information, social security number. They had to run a full federal background check on me, so they did all that stuff. I was approved to come onto the prison site.

Okay - and i can say this because whatever i mean again, this blew me away with the lack of security. Maybe things have changed, but so i was approved to come onto the prison side. I'd never been on something like this, so i pull up to this parking lot in front of the women's prison and they said uh come into the you know, receptionist area. So as i'm getting out of my van, i show up at the time i'm supposed to.

I start walking into the reception thing and as i get halfway there, i realize i got my pocket knife in my pocket and i'm like. Oh, i can't have that so i walk back to my van put my pocket knife in there. So now picture this. I walk into the reception area and, as i walk in there's a giant glass panel with a lady sitting behind it with a little speaker, chingus on there that she's talking to me through and then to my left, there's a metal detector and then there's a waiting Area on the other side of the metal detector, so as i'm standing there talking to the lady, i said: hey you know, i'm scheduled to be here, gave her all my information.

She looked me up. She goes okay, i'm waiting for your escort because i had to have an escort that stayed with me the whole time she goes, while you're waiting for your escort. What i want you to do is go ahead and go through the metal detector, so she goes empty out your pockets contents on the counter and then go through the metal detector. So i emptied out my pockets.

Contents went through the metal detector. Then i circled back around to the reception desk. I cleared the metal detector and she said you can go and put all the stuff back in your pockets. So i put all the stuff back in my pockets.

Now i'm telling you guys this doesn't sound right, but i'm telling you there was not any cameras pointed at me when i pulled the stuff out of my pockets and she could not see what i pulled out of my pockets. Okay, now, once i went through the metal detector - and i circled back around, my escort came and got me and we walked around the metal detector and went back into the prison. Okay, then my escort's with me and mind you. What i forgot to tell you is the entire time: i'm doing that, i'm not kidding with you, everybody that was there because guards and stuff were walking in and they had volunteers and stuff.

They would bypass the metal detector and go into the building. So at that time, again, maybe 10 years ago, something like that, i'm telling you that's how they smuggled crap into that prison, because the people, the volunteers and the guards that were walking in through were going right around the metal detector and again i emptied my pockets Out there was no cameras pointed at me. They did not know what i pulled out of my pockets and i went around the metal detector. When i went with my escort.

Okay blew my mind. So then i get into the prison and the escort's. Taking me to the to the kitchen, the commissary, whatever they call it, and he takes me into the walk-in freezer and i'm standing in the walk-in freezer. My escort's standing there with me and his radio goes off and he says hey.

I need to step out for a minute and take this call, and i said okay, so i'm just measuring up the walking door and an inmate walks in okay as a female inmate. She was pretty big, pretty butch looking and she probably would have had her way with me, but she didn't okay, but again i was blown away because number one they didn't know what i had in my pockets number two: they let me alone with an inmate. Okay. Now this wasn't a maximum security.

This was probably like a low security. It was women's chino women's prison, but it blew my mind that i was left alone in the walk-in for a good five minutes. While i was measuring the door with an inmate again when i could have had anything in my pockets, then when the my escort came back, i measured the door. I was looking at this thing and it was like an old antiquated walk-in.

It was just like it was going to be a nightmare, so i remember, and then, as i was done, i was asking i was like, so how does this work dude and i'm like? Where do i park? My truck like i need to bring in all my tools like how do you have to him and he goes yeah. We got to inventory everything in your truck at the time i had a service body um, i think, or maybe i had a van. I don't know but anyways he said yeah you're going to park your we're going to let you drive on prison property you're going to park in the middle of the prison grounds. There's a caged in fenced area, where we let vendors park you're going to park your vehicle there and every tool you need.

A guard is going to check you to make sure you take it in and bring it back, and i just remember thinking this is not something i want to do and then they said they had to inventory my entire vehicle and i'm thinking i got razor blades. I got all kinds of crap in my vehicle. It just sounded like a headache. So, as i was leaving that job, i remember telling the guy dude this isn't something i'm interested and he's like look.

He goes please please, please. He goes just submit a bid. He goes make it so stupid expensive. He goes.

We just need multiple bids, he goes so just just submit it, and so i made that bid so stupid high that i would never get it, but i was blown away with the lack of security and i'm telling you they. So i knew that moment when i was in there how they get crap into those prisons. It was insane so um yeah, exactly all right. Uh, hey ralph, see you later bud.

Okay, um yeah. Exactly i. I could not believe um how much crap was inside there. It was just so i mean how how much how much i could have taken in there so yeah exactly are we playing a drinking game every time i say chingas or what that's funny steven ask him if it's still the same man, because that blew my mind, Chungus, that's funny all right cool.

Thank you very much for that super chat man. I really appreciate it all right, um, okay, so on my list of things to talk about right now is let me go to this right here, um, so uh. My last two videos that i had so the first one that i had on 8 27 was it's 120 degrees outside and the ac is not working so that one got quite a bit of feedback. Lots of people were asking, you know, so that was one where i took a second technician with me: okay, so first off one of the big questions i get in my videos is um.

How in the heck do i build a customer for all my time? Okay, i'm not trying to be a punk, i'm not trying to make it seem like i'm better than anybody or anything like that. But when it comes to certain jobs, it is what it is. Okay, i quote those jobs for two people: okay, so that particular job um. For that ac, with the heat pump, i think i quoted that for uh two technicians for eight hours, each so so for 16 hours, and i think we might have spent a little bit more time than that.

Even though the customer approved the quote, we even told them hey, we spent more time and they increased the amount. Okay, i try to be fair and honest with my customers. So that way, even when i do a job that i quoted and i find out that hey, you know what it took a little bit more time. I bill them the difference and they pay it okay, but on the flip side, whenever i quote a job, let's say i do a compressor change out and i quote it for two guys: eight hours each and we get it done faster.

I only bill them for the lesser amount. Okay, i try to be as fair as possible to the point that my customers start to trust me, i'm starting to get the coke nose right now, guys all right, let's see what we got uh, oh, i didn't bring enough today. I got ta limit myself to three because i'm getting old - and i can't do this stuff anymore um, so the next video that i had was uh so anyways, oh so for that video right there. So i had quoted that for two guys.

We were there. We set up the easy up, it was 120 degrees. Outside that day it was nuts um. You know, i talked about trying to hydrate staying hydrated eating food and all that good stuff um.

You know those things they just wear you down and as i was leaving that job the customer said hey you know, or they had told me before.
