So this the most common way I go about doing a leak check, I share a few tips and tricks and as usual give the customer the most honest and thorough diagnosis I can.

Before the video starts, if you guys wouldn't mind, do me a favor and check out my website hvacrvideos.com, we got cool merch available on there, uh zip up, hoodies, hats and uh. I don't know if people really know too, but we also have women's cut v-neck t-shirts. They're in the flag style shirt so check out hvacrvideos.com for more information thanks so much. Why are we doing this? Well, because our unit has a head pressure.

Control valve head pressure control valve. Is there to flood the condenser in the lower ambient temperatures when it's winter? Basically, okay, and it maintains the easiest way to explain it - is it maintains the head pressure at a higher head pressure? This video is brought to you by sportlin quality, integrity and tradition. Okay, our complaint today is that our walk-in cooler has a refrigerant leak and complaint. I mean i had a service tech here yesterday he had to put 10 pounds of gas in the system and uh.

We did not look for the leaks yesterday, so we're going to dig into this today try to find the leaks. He said the coils are in really bad shape, but we need to go through it and be 100 sure. That's the problem. Okay, i'm going to go ahead and start up here at the roof uh.

This is a kyrak refrigeration rack. You guys have seen me work on these a lot. I have quite a few restaurants that have this almost identical rack, so um just walking up, of course, we're here to do a leak search, but we're still paying attention to everything, and we noticed that the condenser fan motors are cycling. I just saw those running this one's running these ones cycle on temperature in this rack, so you have these uh, there's, basically a bunch of temperature, clamps wired in series or no pressure control.

Here you go it's a pressure control. So it's a fan cycle control, um and they wire them in, i believe, series or something like that to where they can stage off different fan motors. So this is my compressor right here. This is the walk-in cooler system, a it's currently not running, so we need to wait for it to turn back on.

It looks like it just shut off yeah just shut off, because the suction line is still really cold, but it's not running. We need to wait for it to turn back on then. What i'm gon na do is uh shut down the entire rack, but we need to wait for it to turn on because currently right now, it's pumped down. Okay, and what i mean by pump down is the liquid line solenoid valve downstairs has shut and when it shuts, the compressor continues to pump okay and it pulls all the refrigerant out of the low side and then traps it on the other side of the solenoid Valve so essentially, all the refrigerant is backed up from the liquid line.

Solenoid valve downstairs all the way up, the liquid line into the condenser and it's stopping uh, basically inside the compressor at the high side port and doesn't allow it to go into the low side. Port, so if we tried to do a leak search when it's pumped down theoretically, we might not find or theoretically isn't the right work, but you might not find the refrigerant leak because majority of the time the leaks are downstairs uh in the evaporator section. So you want to have the system on so when the compressor starts up, we'll, let it run for a second and then i'll shut off the breaker, okay and it'll. Let the pressures in the system equalize out now.
I could also do this by applying service gauges and equalizing out the pressures with the service gauges. But i've said this before i'm going to try to do a leak search without putting service fittings on everything, because once you start disturbing the caps like right here and on the receiver, you might uh miss the refrigerant leak or the refrigerant leak might be at the Service cap, or who knows so i like when i can - it - doesn't always work out this way, but because i know for sure there's a leak in the system. I would love to do it without applying service gauges. That way we can uh um.

You know check the places where we might put the service gauges to if that makes sense all right. My compressor just turned on so now we're going to come over here and turn off the compressor, okay um at system a like that and uh we're gon na. Let the so the liquid line, solenoid valve downstairs is still open and the refrigerant pressures are equalizing out, meaning that there's still pressure on both sides. So all the pressure in the high side is going to go to the low side too, and it's going to equalize out.

This is going to make my leak search a lot easier. Okay, we shut down the compressor, but i'm also going to shut down the rest of the rack, but got to be careful. Okay. Sometimes you can't do this all right.

There's lots of equipment running off this rack. This particular rack doesn't have it anymore, but the ice machine condenser fan motors for the hoshizaki ice machines used to come up to this rack. If i had shut this off before without shutting off the ice machines downstairs, the old machines would have gone off on high head pressure because there's no communication. Okay, these ice machines have since been removed from this rack because i know it so i understand this equipment.

Okay, but still i'm about to shut off all of their equipment, walking, cooler, beer, walking, regions everything, so you got to be careful again, keeping the customer in the loop. So they know what's going on, they may see temperatures go up on the other regions, but it's just temporary all right. Today, i'm going to use the inficon, detect, stratus leak detector and we're just going to start leak, checking on the roof and some common places where i see leaks now, i'm on like the super mode. Okay, so i'm not using cloud hunting or anything like that, and i dig how this one has a battery indicator.

You guys know what i'm talking about. Actually that video, where my leak detector ran out, was working on that system right there, but anyways um. Okay. So we're just going to start at the bottom of the receiver.
Some common places these service valves is why i didn't want to put service gauges on. I wanted to see if maybe it was leaking at the caps. Once i check the caps, then i don't mind putting service gauges on so check. The high pressure relief blowout thing nothing down below.

Okay, we're gon na go in some awkward spots right now up on top of here, there's a lot of dirt up here. So you got ta, be careful and i'm gon na leak check the bottom of the condenser real, quick, nothing. One thing, one uh bad thing i'll say about this leak: detector is the the speaker's not loud enough. It doesn't get loud enough at all and uh.

I've got it set as loud as it'll go, so that's off and that's as loud as it'll go, and it's really really quiet. Don't like that. I wish it was louder. So i'm not picking anything up here in here condenser is not too bad.

It's a little dirty, but certainly i've seen worse. Okay, let's look right here: okay, nothing! Nothing! So we're looking good over here check on the dryer, nothing! Okay, looking good on this side, so we're gon na go ahead and jump over to the other side. Now i didn't show you, but i checked the other side of the condenser, maybe a little bit of oil on this condenser in here, but nothing looks like it's jumping out at me. Saying hey, i got leaks here.

I got an exhaust fan running right next to me, that's kind of drowning out the noise of the leak detector so again bad side. Is you really got to listen and pay attention to the little led readout, because it's just not loud enough, so i'm not seeing anything jumping out at me up here come down here, certainly some dirt on there. It doesn't look like oil, though pressure controls. Don't ever ignore your pressure controls.

I'm always check your uh pressure. Controls too. These are notorious for leaking the bellows, a blowout, nothing! So we're looking good um all right. I think we're gon na have to jump down to the evaporator sections all right before i go downstairs, i'm going to power everything else back on, except for the compressor i'm working on, but when you had racks off or any equipment off for prolonged periods of time, You want to stage it as you're turning it on you don't want to kill them.

Okay, with a super high inrush of a current so start with the condenser fan motors. None of them start up because they're all still hooked up to the pressure controls and we're going to leave system a off. So we'll start with e. I usually give it a count to about 10 seconds 5 to 10 seconds and then we're going to move on to the next compressor, okay, and just do them slowly at a time.

What you'll notice, too, is if you've had the rack off for a very long time. This is actually another great time to check sight glasses, because majority of your stuff will likely be calling now. But it sounds like that. One didn't turn on so because i haven't had this off for more than 15 minutes so and i'm listening listening to stuff startup listening to the sound of the equipment, we're just going slowly in the summertime.
This is when this really really happens to be a problem. You notice that i have breakers. These are the old ice machine condensers that aren't being used anymore, and i have them labeled, not in use. So okay everything's turned back on, except for the walk-in cooler we're going to leave the walking cooler off at the moment and uh get on downstairs and start leak, checking those evaporators and just to illustrate my point before i went downstairs, i went ahead and put my Uh, it's not r22.

By the way it doesn't matter right now, but it's 404.. I went ahead and put my service gauges on the system and you can see that we have. I haven't equalized anything out of my gauges. We have 88 psi in the low side, which is great for leak searching, but because i'm done doing the leak search on the roof, i don't mind interrupting the uh, the the seals and the the fittings and everything right, because i already checked everything.

So i'm gon na go ahead and furthermore, uh equalize my gauges out on the roof and do a more thorough equalization, not just relying on the solenoid valve, because i was thinking about something. So now i open the high side and the low side and the pressures are gon na be equal, but i was thinking about something we also have a solenoid valve over here that probably lost power when i shut off the compressor breaker. So this time what i did was, i just pulled the molex plug out of the compressor um and turned the breaker back on. So i was thinking.

Maybe it would open that solenoid, but even still opening that and that we still had a decent pressure differential between the two. So i went ahead and equalized it on my gauges. Okay, so now compressor's not running system is equalized. We're going to go down and uh leak check the evaporator all right.

Only after i equalize the system out, i shut off the fan breaker so that way, we're not moving air and we're going to start disassembling the panels and doing a leak search um. Also, unless you want to smell like a butthole, that's been eating solid for weeks on end um. You want to put some uh rubber gloves on when you're working in these boxes, because just the stuff, the prep table, funk smell or whatever is in here and it's nasty man. I hate getting out of my hands because it's stuck there forever.

So i always try to wear rubber gloves whenever possible, working on these things, all right start at the ends. It's usually not leaking on these sides start at the bottom. I like to start at the bottom of the coil right down in there and see nothing and then just kind of work. Your way up these leak detectors are super accurate.
Usually so you usually pick them up by now again chasing the bottom here and then do the same thing right here. It doesn't look like there's anything on this side, so we'll jump on over to the other side and see uh what we can pick up over there. I uh nicked the insulation just a little bit to get inside of it, not picking anything up in there checking right here. Nothing i mean i should pull back that insulation, but i would think the leak detector would be picking something up again.

We had to add 10 pounds of gas, so i think it's it's either a really small leak. That's been leaking for a long time or it's a big leak. I don't think it's a big leak, but i think we would have oil build up or something. Okay.

Again start on the bottom: where can you look at that? Oh there's, one already start over here, don't just assume, because you find one that that's all of them keep leak, searching we'll get some big glue on that here in a minute. Okay, so definitely right there. Let's keep going over here. These caps are notorious for leaking not seeing anything over here for the these coils are from, like 2004 they're doing pretty good something over here too yep down in there.

So we're gon na get some big blue all inside here. Let's see what we got, okay, so let's go get some big blue and then we'll do a leak search on the other coil, remember um! So i'm using some big blue love this stuff when you're spraying it on you want a steady stream. You don't want a bunch of foamies, you don't want to use the fan. Setting the steady stream makes it easier to see leaks faster because just nice and smooth and if you go smooth, then typically your bubbles are going to become the leak point.

So we're going to get right down in here and i'll, get you guys a shot of this right down. There is where it was leaking by spraying with a nice, steady stream. You see how there's no residual bubbles left. We come down here, so we can get this for you guys.

You can actually see it right. There is our bubbles, that's our refrigerant leak. It's right up there! So what's interesting was the leak. Detector was picking it up on that bottom piece, but it was really the refrigerant falling from the top right there.

Okay, so we're going to continue leak, searching on this side too right there there's a leak, so we've got multiple leaks on this evaporator. Now i've got the big blue seating on everything else and we'll give it a few minutes, because sometimes the big blue will even pick up leaks that the leak detector won't. I'm not seeing that at the moment same thing with this side, we'll let it sit for another 10 minutes and then look for any more micro clusters. But we got two leaks, one on each circuit of this evaporator coil.

Well, one on each side of the evaporative coil, there's actually four circuits, so this side has got leaks all over the place. I think we might be picking one up right there, possibly there's. Definitely one right there, there's definitely one over here. I can hear this one popping right down there so they've got.
This is the other coil now so they've got leaks all over the place in this thing, and these are the leaks that i can see, we don't know if there's more, i was picking up something in this corner over here too, but i'm not seeing it, which Makes me wonder if it's inside the coil wow interesting you got to let the big blue do its magic there. It is. I knew i was picking one up in that corner. There's a leak right there too, so this coil has one two three at least three leaks and we still haven't done the other side or the actual coil itself.

Okay came over here, i'm not picking anything up on this one. It's kind of running through nothing, nothing went ahead and went right over here. You know, run the bottom of the coil, looking good, okay, no problems, but right here, a pickup leaks. So the question is: is that just picking up the leaks from the other side or is it leaking in here too see? I think it's leaking in? Here too? I think this one's going to be a candidate for a new coil.

I will certainly give the customer the options and give them a repair quote, but if i tell them, i certainly think i could possibly repair that other coil, because it's just two leaks on a braze joint, but that coil's the same age as this one. These are from 2004, so you know, their best bet is to change both coils, but you know times are tight right now with this covered stuff, so i don't know we'll have to see, but i'm really going to push them for at least one evaporative. Well, at least because this one i can't guarantee anything - i mean even that one i'm not going to guarantee anything, but i i think i could fix the other one. You know, but again it's their money i'll.

Let them make the decisions on what they want to do so, i'm up on top of the box. It was a tiny, tiny, little access hole, but luckily it's kind of closed in up here. So it's not too dirty a couple things i'm going to do a leak, search, real quick on these lines. I'm not going to rip all the insulation off, but i'm going to poke a little couple holes but look right there guys! That's a liquid, lined solenoid valve up on top of this box.

You can't just assume things and installers they never think of us. That's the stupidest place to put a solenoid, but it's cost effective, essentially because they didn't have to run a return pipe from one coil to the other. The better bet would have been to run a liquid line to one coil, put a solenoid in a t and then go to the other coil yeah. It's not the best piping practices, but it's the most practical, for you know, repairs and stuff.

So we got to make sure that we know that there's a solenoid valve up here, but i'm going to do a quick leak search of these lines right here, just just real quick just to try to give him a big picture quote all right. We're going to turn this guy back on. I've got to uh turn the breaker off, put the molex plug back in the compressor uh i front seated the king valve on the receiver, so the compressor is going to start up and the system is going to pump down. So i can check the liquid level in the receiver uh.
I believe my technician filled it up to the three-quarter level yesterday, so i will uh double check that level and verify with him, and then we know if i need to add gas, i doubt i'm gon na have to because i don't think it leaked out anymore. Very much since yesterday, and also another thing, i wanted to point out too, that you saw pretty big bubbles coming out of that evaporator coil, but i had the system pressures equalized. It's not going to be. If ever that, you're going to have a 100 psi suction pressure, you're typically going to have about 30 psi suction pressure, so it won't be leaking out as fast.

Essentially, because we have you know higher pressure, basically creating a pressure differential, pushing the gas out of those those leaks faster right now, so let's pump it down and see where the liquid level is so. I just got off the phone with my service tech and he did not fill it up to the three-quarter level um. He said that it was about halfway and that's right about where it is. Is this mark, so i'm gon na go ahead and fill it up to the three-quarter level, because we know that's the maximum amount of gas we can put in here this way it lasts longer until the customer can uh approve my quote to repair it.

Basically so we're gon na add some gas, so i'm kind of cheating um. I didn't open up the king valve and i'm slowly adding gas to the system. But i got to be careful because you don't want to flood the compressor, so i still have it pumped down i'm adding it through a schrader, though so, but we're just going a little bit out of time, making sure it doesn't shut off again. I have the actually, i won't shut off without the pressure control bypass, so i'm taking a shortcut but there's consequences to this shortcut.

If i put too much liquid refrigerant in there, i could ruin the compressor um. You know you can cause issues, so you got ta if you're gon na take shortcuts. You need to really know the consequences and understand how to prevent them all right. We can clearly see the temperature right here 105 and then, as you go down, it's going to drop and drop okay.

So my liquid level, though i'm feeling with my hands that extreme heat is right here, so uh we're gon na go ahead and mark this at the three quarter level: okay, so we're gon na mark our liquid level right here and then that way we know. So, let's talk about this liquid level here. Why are we doing this? Well, because our unit has a head pressure. Control valve head pressure control valve.
Is there to flood the condenser in the lower ambient temperatures when it's winter, basically, okay, and it maintains the easiest way to explain it - is it maintains the head pressure at a higher head pressure? Okay, now there's more to it, it's really about the pressure differential at the expansion valve, but the easiest way to understand is the head. Pressure. Control valve keeps the head pressure up in the winter time. Okay, so with that being said, it floods, the condenser, meaning it slows down the flow of refrigerant out of the condenser, sometimes stops it and allows liquid refrigerant to back up in the condenser.

So if you think about it, like, i said the easiest way to explain it, is it's raising the head pressure, it's similar to blocking off the condenser, but not the same, but it's the same concept: okay, blocking off the condenser, bringing up the head pressure? Okay, but when we do that with refrigerant by flooding, we need extra refrigerant in the system. Okay, we call that the winter charge uh notice, something too guys, while i'm talking to you. This is actually leaking oil because it leaks these king valves always leak. So you see the oil on the ground so but anyways um, so the the head pressure control valve when it floods the condenser it needs extra refrigerant.

Okay, we call that the flooded charge or another term for it is the winter charge. Now, i'm starting to get a little bit frustrated with the winter charge term, because people are confusing that thinking that you add extra gas in the winter. No, that's not what you do! It's the extra gas that's always sitting in the system for the winter time. Okay! Kind of semantics, but people seem to really need the simplest explanation, so it's not gas that you come in and put in in the winter and remove in the summer.

No, no, no, no you're! Thinking of it wrong. Okay, it's the gas! That's going to be used in the winter in the summertime, it just sits in the receiver waiting to be used. That's all! Okay! So we add the extra gas now. The best way to add that refrigerant is use the spoiling method, or actually the best way is to lean on the manufacturer.

Okay. So if we come over here, this manufacturer, we have it written right here has actually told us that system a takes 14.4 pounds. Let's see if i can get you guys, a better look system, a takes 14.4 pounds of gas when it's fully charged. Okay, that's from the manufacturer, but here's my problem.

I had a service tech here yesterday and he came out to the system. Okay, we know it needs 14.4 pounds, but how do we know is left how much is left in the system? We don't okay, so my tech came yesterday. He filled it up to about the halfway mark. Okay, when it was pumped down - and i came out today - but i don't know where he put it again - not knowing how much refrigerant's in the system - because he didn't mark it - okay, so i'm going to mark this at the three quarter level one is pumped down.
So that way, the next guy knows that's where i left the refrigerant charge now the other method to do - and actually this is what the manufacturer of this rack chirac did - was use the sporlin 90-30-1 method, where they calculated the flooded charge. All that they do is figure out how much internal volume the condenser has they figure out how much they want to flood the condenser as a percentage-wise. Okay, that that's affected by the ambient temperatures and they add the extra refrigerant so that calculated charge they gave us 14.4 pounds. That's the total charge um for a predetermined line set usually about 50 to 100 feet, plus the flooded charge.

Okay. So now, hopefully, i'm not losing you guys, but i'm gon na mark this liquid level for the next guy. Okay, that way they know we left it at three quarters and we'll give the customer a quote to repair this system. All right had a few tidbits of information in here now important thing to understand is remember: my videos are meant to be just another source of information.

It's not the golden rule. You don't have to follow everything in my videos and i'm not telling you how to do your job. Okay. These are just the ways that i approach certain situations.

Certainly when i started the leak search, i was saying hey, you know don't put gauges on the system. That's just one method, and i do that for a certain reason. So that way i can leak search the points at which i'm going to access the system, because sometimes you walk up to a system and there may be a small leak at the king valve cap. Like the the actual cap that goes over the um, the stem for the king valve and when you take the cap off or when you start adjusting the king valve, you may inadvertently fix that leak, or maybe it's leaking at the quarter.

Inch cap, where you're gon na put your service gauge and when you put your gauge on there your hose on there, you don't you know, you fix the leak. So that's why i'm saying you know start if you can, but there's a lot of variables that go into that. You have to know the system has gas in it. There's no point in leak searching a system if it doesn't have any gas you know.

So you got to understand how the system works and use your your brain power to know whether or not that's a good method. Certainly, you could simply put your gauges on a system right away, equalize out the gauges and call it a day and you'll have sys you'll have pressure on each side of the system? Okay, but you also have to pay attention because, depending on what you're working on, if you work on some supermarket style systems, if you work on um fish cases deli cases, there might be suction line, solenoid valves and liquid line solenoid valves - okay, i've seen it. So you know, assuming equalizing your gauges out is going to pressurize the evaporators, not always the truth. So you need to understand how the system operates.
Okay, if you have a liquid line, solenoid valve and a suction line, solenoid valve - and you turn off the power to the system and you think you're leak checking the evaporator. You could be wasting your time because there's no gas in it or not enough gas in it. Okay, so you really need to research, and this isn't just a follow - a video and and go become an hvac service technician. That's not how this works.

Okay. Now i certainly realize that people that are not experienced in hvac watch my videos and i certainly realize that some business owners and homeowners watch them and and that's great okay and no offense to anybody. But these videos are meant for service technicians um. You know someone has to be pretty um, you know intuitive if they're gon na watch my videos never working on a refrigeration system and then work on one.

Okay, that you know, i try to leave out some of the core information. So that way, you know, i'm not um, empowering everybody to go out and work on their systems. First off, there's a lot of safety reasons, but you know, of course i don't want to take any other contractors, jobs or anything like that. So anyways that's a whole tangent um.

I said it in the beginning of the video i'll say it again. If you guys haven't already, do me a favor and go check out my website. Hvacr videos.com lots of cool merch available, i'm wearing the zip up, hoodie sweatshirt right now. The hats beanies uh shirts, and i said in the beginning too, you know a lot of people.

Don't realize that i have women's cut uh v-neck t-shirts on there too, so they fit differently, they're, actually women's sizes in them, and my wife says that the sizes are very true to the actual size. If that makes sense, i don't know what that really means, but so check it out. Hvacr videos.com, so about this video too, you know doing the leak search. You cannot just stop at the first leak, guys.

Okay, don't do that remember these videos are made for my employees, so i'm literally talking to my employees, you find a leak. You keep going. Okay, yes, there's certain situations where the leak is so big that you can't find any other leaks. Okay.

But in my situation we had very small leaks and i'm going to be honest with you. My service tech had to put 10 pounds of gas in this the day before. Okay, to be honest with you, i don't think i found leaks that would equate to 10 pounds of gas being lost, so that kind of makes me a little anxious. So that's why i went above and beyond to climb.

On top of the box, look at the rack because we're leak checking the whole system. You got to make sense of this guys. Okay and experience tells me that, yes, these leaks, they could have been leaking for a very long time and that's probably what happened was it's been slowly leaking out and it finally hit the breaking point where the temps just hit the fan, you know and uh, and It became an issue, but you you got ta, you know use logic, you don't just go into this again here we go, don't go into this with your blinders on and your headphones on and just think you're going to go to work and just pass the time. This is a job that you need to invest yourself in okay, if you guys are coming to work every day, punching a time card and bouncing and not thinking about anything else, you may survive but you're, not advancing yourself and you're, not bettering yourself.
Okay, you need to be invested in this job. You need to have your head in the game. Okay, if you guys have personal stuff going on at home. I know it's hard to let that go.

Take a couple days off get yourself into a position where you can come to work and focus on work. Okay, so you know i'm just trying to say you need to really understand and make sense of what's going on and think. Logically, okay, you know what i found a leak, but that doesn't seem like you know, it's a big enough like there's nothing better to a service managers or an owner's ear when a tech calls them and says, hey man, you know i found some leaks but dude For the amount of gas that i had to put into this and the leaks that i found it doesn't really add up, you know what that means to a service manager and a business manager or business owner, whatever a lead. That means hey man.

This guy is thinking, okay, he's really using his brain power and he's really concerned about this job and he has invested in this job so guys do your due diligence, okay, think about the job be concerned about the customers right. I went to the customer while i was doing this and i was keeping him in the loop the entire time. I was filming this video hey, you know what i'm here, because he my service tech, was there the day before, and i said, hey i'm here, because you know this thing lost a lot of gas and i want to look for this leak because this concerns me. I showed him that i had concern and then, as i was leak searching, you know i had to go get something from my van.

I walked up to the customer. Again, hey man, you know i found a couple leaks, but i'm not going to let it go with that, because i want to make sure that that's all that there is, you know, so i'm going to keep looking again, i'm just keeping him in the loop. I'm making him feel comfortable, i'm building confidence with him, okay and i'm showing him that i'm invested in his business. All right, i'm i'm genuinely invested and concerned, and i want to do the best that i can for my customer.

Okay, building that confidence there's nothing better than building confidence with a customer, okay building, a relationship. So when i was also when all was said and done, i went to the customer and i said: look we found multiple refrigerant leaks and both evaporative coils and i said, look i'm going to get a hold of your facilities department and i'm going to give them All the information and let them make the decisions - okay and - and you know, by doing that - uh i'm also again. This is very customer specific information - i'm gon na give right now. Okay, some customers want a lot of information.
Other customers don't want a lot of information. Okay, so you have to be very guarded and understand and communicate with your management staff to know how you're supposed to communicate with the customers, because this particular restaurant customer. I need to be careful about the information that i share with certain people in the company, and that is by the people that i work for. I've been told, be cautious, okay, um and and just share what needs to be shared.

Essentially, okay and i'm not gon na go into too much more detail, but basically the people that employ me in this business kind of dictate. What information i communicate! Okay and that's all that i'm gon na, say there so um. I have to know that and when i go to the customer and share information, i have to be careful because you know the people that are employing me directly. Paying me have told me: hey keep.

You know certain information between certain people. Okay, all right. I just do what i'm told it's a game that you have to play within this industry, so um probably shared a little bit too much information there, but oh well! It is what it is. So i really really appreciate you guys watching these videos and and again it's still very humbling.

You know uh these, these babbling, that i do at the end and sharing and talking - and you know going on my rants and stuff - it's very humbling to know that people actually listen to the end of here. We are creeping again. Thank you guys so much. We are creeping up on the hundred thousand subscriber mark.

If you go to that and uh, i think to be honest with you, i am the most uncensored person on that show. Uh. To be honest with you, i probably irritate the guys, with the way that i talk and um it's it's almost like a relief like you know, it's just my group of guys that i go to hang out with and man i just sometimes at the end of The show i think god damn. Why did i talk about that? Oh my gosh, what did i say you know so, but it's just a cool hangout.

We usually have a couple beers and just hang out and talk so definitely go check out. The hvac overtime show um. Also, okay, please, if you guys, are considering any tool purchases check out, truetechtools.com. Okay, i have an offer code set up with them.

    Frankly, I'm not going to try to do anything to HVAC beyond cleaning coils and tracing shorts. That follows along with my normal daily job. Once I get to a certain point, I stop and call the tech, give him the information, and let him do his job. Are you in Nepean ?

  2. Avataaar/Circle Created with python_avatars Mike Biron says:

    That many rat traps and rat poop everywhere, I will never eat at that restaurant. Being I have no idea where you are, that means no eating at any restaurant in your whole coverage area. LOL Yuck! Nasty.

    How come it seems these refrigeration racks give the beer walk ins the largest receivers?

    Being a marine engineer working on HVAC systems also, your videos are a great help. On my previous ship we had a leak.. And i recharged a few times a week, but never finding the leak. This explains a lot. And thank you for your time, producing quality content like this!

    Hi Chris. I've been the refrigeration mechanic for 30 years. it is nice to see how you work there.

    it is a lot of old stuff that you have to work on, the customers do not have much money left for maintenance.

    Here in the Netherlands when we come across that old stuff we close the lot from the environmental pollution.

    i'm working here on cooling water installation and heat pumps, keep it up as i love to see it.

    I just started commercial refrigeration segment of my schooling course. We are touching on the King Valve and "Pump Down" and I'm still fuzzy on what exactly these things are. Any word of advice? Service area Barrhaven??

    topping up refrigerant is illegal? REFRIGERANT REQUIRES DECANTING PRESSURE CHECK WITH OFN .I THOUGHT THAT WAS PART OF THE PROTOCOL.IF PROSECUTED IN U.K YOU CAN GET LARGE FINE .OR PRISON TERM. R THE LAWS DIFFERENT IN THE U.S?

  18. Avataaar/Circle Created with python_avatars Robert Richards says:

    That’s one thing that we will find in our industry and working with REFRIGERATION commercial and industrial is the fact that you run into all kinds of foul funk bacteria, mold and as well as asbestos if you get into the older EQUIPMENT. That’s why I have lung issues right now. And I had to bring a change of clothes in the service vans over the 20 years. Because of the foul & funk… as the bad side of our industry. Now I’m suffering as a result of it..

  20. Avataaar/Circle Created with python_avatars DmiesterCommKitchenTech says:

    The leak on the distributor was it on the liquid line side of the distributor if so that is where most of the refrigerant leaked out because the liquid leaks out faster due to higher pressures so 10#'s could last a couple of months leaking there my other concern would be the oil loss was there a oil sight glass on compressor

    I'm in going back to school tomorrow i love your videos been watching from beginning like a few years ago i just want to be a good tech like you i have away to go but with skills& knowledge my time is coming some day as a rookie now

  25. Avataaar/Circle Created with python_avatars ellmann creative says:

    You know, I think it takes some courage to outright say "I, by conscious choice – do not, and will not, explain (or even include) all of the steps required for you to essentially do my job." I mean, duh – it's still your job, and if anything, these provide entertainment for those of us that aren't in the industry (and, at least in my opinion, a lot of good advice that isn't limited to your field besides – "big picture" applies literally everywhere). But I still think it takes something to be upfront about it, risking the ire of folks that will now feel entitled to it, precisely because it's being denied them explicitly (regardless of whether you would otherwise have, or whether it could even be possible to gather enough information to do so). I sincerely hope your viewers aren't like that, though. 🙂

  26. Avataaar/Circle Created with python_avatars CHOMAHOMA says:

    Thank you for all that information about customer service that you share. It is very important as well.

  27. Avataaar/Circle Created with python_avatars Ronald Fourfive says:

  29. Avataaar/Circle Created with python_avatars Zachary A says:

    I'm not a service tech but I am a mechanical designer for process chillers. I get to do some refrigeration design work sometimes and its nice to see your vids because they give me the perspective of a service tech when designing units.

  30. Avataaar/Circle Created with python_avatars Toyin Orodare says:

    I am learning greatly from your channel thank you for this in-depth knowledge you are passing across

  31. Avataaar/Circle Created with python_avatars Robert Hartley says:

    That's how I train new guys in my air guard unit coming into hvac. Check with an electronic detector, use soapy bubbles to pin point leaks, then put on gauges to see how low your pressures are and see how low your charge is and also to see if there are any other issues in the system. Putting gauges on before checking everything else can cause missing something simple like a leaking Schrader core. Great video keep it up man.

  32. Avataaar/Circle Created with python_avatars Frank Montefusco says:

    I love the end of the videos, very informative!!

  33. Avataaar/Circle Created with python_avatars Vaidas jakimavicius says:

  34. Avataaar/Circle Created with python_avatars Pete Moss says:

    Biggest lesson I learnt was when it comes to sharing info with a supermarket manager, play it close to your chest or better still keep shtum, and deal with their facilities manager instead!

    If the rack cannot handle the inrush of all equipment starting at the same time, they are going to have a lot of troubles when there is a power failure

  37. Avataaar/Circle Created with python_avatars jet224presents says:

    I’m no tech but watching your videos has helped me understand more about hvac and diagnose/ repair issues like the capacitor and condenser fan at home. It also helps to have hvac techs in the family!

  38. Avataaar/Circle Created with python_avatars John Walker says:

    Your a good teacher, so far.

  39. Avataaar/Circle Created with python_avatars GradertFamilyMakes says:

    Best case scenario, replace the system. Worst case scenario, they hit half the BoM because the pandemic has them broke.

    Also, in my world, the customer needs to know enough information to make a decision and that is it.

  40. Avataaar/Circle Created with python_avatars GradertFamilyMakes says:

    I am not a service tech, but I do feel as if I've learned enough by watching to have a very good understanding of what goes on. As a result, I may do well if I do become one.

  41. Avataaar/Circle Created with python_avatars FLoat Sam says:

    information asymmetry is a big thing in almost every larger business, especially with multiple parties and billing/contracts involved.

  42. Avataaar/Circle Created with python_avatars abhijeet chandra says:

    I use a leak detector called KIMO it’s perfect works every time plus it does nitrogen so you don’t have to put trace gas in the system to look for leaks 👊🏼

    Have you gotten to the point where you’re buying big blu in 55 gal drums yet? 😂

  44. Avataaar/Circle Created with python_avatars Mark Caldwell says:

    Good job and excellent point on the tech not only needing to know sequence of operations but also needing to think like and installer sometimes when servicing. Are you in Orleans ?

  45. Avataaar/Circle Created with python_avatars Randall Weaver says:

    Good video! Almost at 100k subs!

  46. Avataaar/Circle Created with python_avatars Jonathan Schulz says:

    Very cool that you emphasize customer interaction. A lot of customers are more willing to approve follow up work if they trust you and understand what needs to be done. You have to sell yourself more than repairs/replacements.
