This started out as a normal service call than spiraled into a disaster, the evaporators were iced up so I de-iced them than found bad powerheads and a plugged strainer, than found a dirty condenser coil and a bad compressor.

This video is brought to you by spore'ln quality, integrity and tradition. We have a service call of dear walk-in. Today, looks like it's frozen up in the temps in here about 50 degrees, and it looks like we've got some frost going on there too. So we're gon na dive into this and see what we can figure out looks like that panel had been left off too.

So this coil we found that the power switch, which is right over here, was off. We turned it on and the fans turned on and it's defrosting, but this is a freezer coil and it does have electric heat, so we are going to have to finish defrosted it. However, the other coil. On the other side, the fans will not turn on so we're gon na have to dig into that one, and this is the far coil look at this - I'm gon na figure, this crap out and all that burnt goodness there.

This looks nice and toasty in here. So it looks like this was never hooked up correctly from in the first place, because I'm following the schematic and there's not even anything going to the neutral or the end terminal, some call it a neutral, the end terminal or the common terminal on the fan delayed. Defrost termination switch that's what this is this, because it's a ceiling mounted coil and it has two coils. They use this style instead of the clicks on so there's no yeah, it's just not hooked up right nothing's.

It looks like this is a mess and look at this big 6 gauge wire. It looks like and like the fans or stage like they just want to randomly just turned on right now too, so it also from the looks of it. This isn't working right this all that so we'll have to clean this out, replace the switch see. What happens this is the other coil.

This one's got some burnt wires, not as bad, but what are they doing with that? Six gauge wire going to a 12 gauge or 14. The flowers have one object as a mess. You see. We're gon na have to do a bunch of work here, get this cleaned up, so my control section on the roof.

There's a lot of mess going on up in here. This isn't what we're dealing with, but look at my condenser fan motor contactors are disconnected. It looks like oh no, these are ice machine, never mind yeah, but still I hate when steps bypass. These are bypassed that contactor, it's like.

Maybe it was a bad contact or something I think they have separate condensers now, if I remember right, we'll see for their ice machine, so these may not even be in play anymore, but look at your condenser fan. Motor fuses are all bypassed, and then this is our time clock for that system. Nothing funky! I checked the voltages, that's correct! Everything looks good, there's a separate contactor for the heater circuit, we're probably going to throw this into defrost and defrost those coils up, which I just did that right now, but see here's the thing that contactor shouldn't have pulled in yet because there should be an interlock On the compressor contact or see the compressor, contactor still pulled in it just pulled out, but the defrost heater contact are pulled in before that one pulled out. Typically, you have an interlock here that stops that one from pulling in when the compressor is still running so we'll have to figure that out too looks like we got a faster.
So when we come out of three, which is our defrost terminal, the power goes up on this black wire right here and it wiring us right here to me, this looks like someone disconnected the auxilary relay that should be on the side of that contactor, because for There to be a junction point right here tells me that that auxilary relay should have been right there, and I know that this rack originally came with that, so that auxilary relay needs to be put back in there. So that way, there's no possibility that the heaters run when the compressor is still running. So that's one thing, but I've just kind of evaluate everything before I jump into this, because this is kind of a mess I'm trying to make sense of. What's going on here downstairs with the wiring and every I understand.

The difficulty here is that they have a separate power source for the defrost heaters, which is right here and there's going to be separate voltage for the defrost heaters right here. So I got ta figure out what they're doing there, because the wire size is changing, which is strange, so we're still trying to make sense of it. So I've got the unit in defrost and the defrost heaters are actually taking care of the frost pretty. Well, you see the coil inside there looks like it's defrost and pretty good my theory, without I'm still trying to make sense of what's going on here, but my theory is is that this coil is getting too hot because defrost terminations, not hooked up, is my theory, But I don't know if that's the case yet we'll see you got a defrost heaters right down there and the heat coming off of that's pretty intense and it's just coming up and melting this covering because they're being put in defrost too long.

I bet so. We will see so this thing's a mess and my my I'm trying to rationalize what they're doing here make sense of it. I mean look at this. This is a heater wire and they're going from like six down to a 12, and that 12 is rigid, because obviously it's running super high amps through that 12 gauge.

I think those heaters were pulling almost 20 amps. That might not even be at 12. I bet you that's a 14 because it's got a thick jacket on it. That's just like a cluster, but honestly this is just a beer, walkin and they're.

Only maintaining I mean they can't get any colder than 32 degrees in here, because they've got bottles of beer. So I'm gon na make this unit air defrost and we're gon na eliminate all this electric defrost BS, because yeah they're, not the set point on this box is 36 degrees. So I just I don't understand why they have electric defrost here, so we're gon na make this guy air defrost we're gon na, and this is gon na solve our problems. I just got to figure out the wiring.
It shouldn't be too difficult, we'll disconnect that second contactor and go from there so up on the roof. I disconnected the coil voltage to the heater contactors and that was all running through here and then I disconnected the number three wire I disconnected the X terminal. So now we're just going to have one which is power to the clock and n, which is power to the clock. And then four and n are going downstairs on blue and black right here and we're just going to wire the fans constant down there.

And then we'll test everything and make sure it all works. When I am done, I will write not in use on everything: that's dead and we'll go ahead and pull these wires. That were going downstairs to the heaters and we'll cap them and put the cover, because all the covers for the contactors over there we'll put the covers back on and write not in use on this one, I'm gon na open this up. I bet you anything.

This contactors hitted, so we might be changing that, but we'll see so that's what we're at so far. This is the two wires. So this is like a six gauge or an eight gauge, and it's really rigid - and this is like a 14 gauge and they were going from that to that like, but from the 14 to the whatever, so we're just gon na clean this up and cap. It off so nobody gets confused.

This isn't gon na be too difficult at all and from the looks of it, this thing was never really hooked up right, anyways because yeah, it's just a mess. There was no fan delay in the picture for the fans originally. So all right, so all the wires that are being used are just capped them off. Now we literally, I left the heaters hooked up to their terminals, just so that there isn't a bunch of dangling wires, but there's nothing going to them.

We literally just have our fan motors here and you got one leg here, jump it over to that, and then you got one leg here going to that, so the fans are running 24/7. This thing has screws from the other side, I'm not gon na bother ripping the coil apart just to get it out so and on another note, if I wanted to change that, the capillary won't come out of there. So it's a mess, but this should work now. We're gon na do the other coil.

This is my other quote. If you guys were paying attention to what I was doing on the first claw, you should have been screaming at me because I wasn't thinking straight. I was gon na power, the fans off of blue and black. The problem is is that one of those wires gets disconnected by the time clock so that way it can pump the system down when it goes into defrost.

So I can't power the fans that way. So I do have an extra wire in here and that was a white wire coming down. We're gon na use that to power the fans so that the fans will have to constant power sources and then the switch to Lake will be the other one and that'll just be disconnecting the solenoid valve. So that way, the system goes in to pump down all right.
So now I fixed it. The white wire and the black wire are gon na do power. For my fans, the blue wire gets capped off because that's power from the time clock. That's gon na go to the temp control in the solenoid off, so that's just not being used there.

So this should not work so we're not gon na put any covers on until we go upstairs and wire everything up there and then test it all. So if I wired this right, this should work right here and we're gon na test everything right now and we'll sit tight everything up to make it look clean, but yeah we'll test it on see, hopefully everything, okay. So now it's all set up and we tested it. So we leave this one off, but it's not going to hurt if we turn it on, because there's only power coming into the top of that contact or nothing went out.

Here's the old wires for the heaters. We're going to clean all that stuff up we'll get zip tight crazy up in here. You can see obvious that you I'm not going to dig into this right now, but this X terminal is disconnected for their walk-in freezer anyways. We'll get to that later.

This right here I put in a new defrost clock too, because I figured I'm in here. I might as well with all the work that I'm doing. I want a better defrost strategy and I was just didn't want any problems now. This is a test.

There's a possibility that we could still have defrosting problems, because you know they're only maintaining like 35 to 36 degrees inside that box, because they store bottles of beer. And so we can't get below 32 and we may set it for 34 or something got. But I think we'll still be ok, but we just got to kind of watch it. I also have to remember that this evaporator coil is a freezer coil, so the thin spacing is different, so that can affect the defrosting too.

So we have to make sure we have a proper air defrost strategy. This is going to be a trial and error. We're gon na see how this works and what happens so we know that right now I have someone downstairs the evaporator fan runners run while it's in defrost, but the system pumps down it's pumped down at the moment. I just took it out and we'll come over here: it'll take a sec for the temperature controller, because it's a digital there goes we cut in about 36 psi.

This location, actually is the one where I have the pressure control issue with the pressure regulating power head, and it's funny too, because I clean the rack that day when I made that video and the racks already plugged up again, it's crazy how fast this happened. Anyways on a psych class, so we're gon na have to figure that out, but now that we've got the defrost strategy fixed, we can look into the sight, glass and see. What's up with that, I pulled the cover to that contactor and you could just tell there's some burning even before I pull those little pulls it's it's all charred in there. So we're gon na change that contactor to new contactors installed.
It's working. I just kind of quickly tied up those wires they're, not going anywhere set up my defrost strategy. So what we did was we start out with four defrost a day for 15 minutes evenly, so eight eight two and two and threw an extra one in midnight, and then I throw an hour-long defrost in the middle of the night. We're gon na start with this strategy and see if we have to improvise or adjust it accordingly.

Important thing I like to put a long defrost in the middle of the night, but this particular restaurant one day a week they get here after like 4:00 in the morning. You want to make sure that defrost strategy is in deep frosting, like that at 4:00. In the morning or they'll call you at 4:00 in the morning to say: hey and my walkins not working, you know and it's like an all reality. This hour-long defrost in the middle of the night, with the door shut, isn't gon na bring their product temp above 41, but the air temp might get a little high inside there.

But you know it's just one of those things. You don't want to panic and call you at 4:00 in the morning, so you got to think about that kind of stuff. So at this point I thought there was low on charge, but it actually isn't the sight glass cleared up. It was just taken a minute after the site.

Glass is clear back there. Okay, we're still going to check super heat on the evaporator. Just because I want to know what the super heat is. It's currently about 88 degrees is 190 I'd, say it's gon na go a little warmer, so so we're just gon na watch it for a bit.

So this is my first coil. My super heats 43 degrees. It's about 43 degrees in the box and my coils got a funky frost pattern going on and then, if you come over here and look at my bow, my valves all frosted up I'll bet you anything. We have a bad power head or a power head.

That's going bad we're gon na look over my other coil doing the same thing crossed eval crossed enough chemical will check the super heat on that one to my second coil is running even higher on the superheated again by box. Temp is 43 degrees. When we look at my coil TV, it's insanely high, so I'm leaning towards these power heads failing if you look at them, they're all corroded at the pains coming off, not not that that matters, but yeah we're gon na change. Those power heads we'll check that strainer to to make sure it's clean, so I went to go pump this down and it's pretty warm outside right now, it's about just under 100 degrees and when the head pressure got up to about 340 psi, the scroll set inside The compressor disengaged and it started to bypass the high side pressure into the suction, so I had to turn off the breaker and let the pressures that a little whether they call it a liquid, not a seal, it's whatever it's some little mechanism inside there, it's separated.
So I had to let that reset then I started it back up and it ran, but when I started it back up, I opened up the receiver, so I was pumping it down when it when it you know disengaged or bypassed. So what I did. I don't know if it's overcharged or if it's because it's a dirty condenser, because the condenser is a little dirty. So I hooked up this hose while I was pumping down and let it shoot some refrigerant into that recovery cylinder as a liquid.

So that way, if it is overcharged, which is my theory that it pumped out liquid refrigerant into there so I'll test the charge once we turn the system back on, quite a bit went into that tank. So now we're going to go downstairs and do a hot swap on these power heads because I didn't want to have to change the dryer and vacuum the system down. So we just pumped it down to about just under 10 psi and I'm going to change those power heads under pressure for about 7.9 psi. So we'll change those under pressure.

So there was a tag that indicated the balance bill on powerhead. So we make sure we put that on so we're gon na change, that power and refresh now the pins might shoot out. So you got ta, be ready and make my life easy. There's no sense in saving the power net.

How about other one ready going with the medium tent? There was a low temp on watch out these pencil shootout, because the type of balance push the power up. There's no strainer to check on this one put my tag back on my power head that way. The next guy knows what size Dalton in this and then we're going to run it to a new spot. It's that way it's actually instead of sensing where it was, which is right here, we're in a sensible reading here, so that one swapped out and then we'll get on the next one.

I'm gon na make sure that the sensing bulb isn't anywhere. Where it's going to rub out. It's got a nice clean line. I took it out of the coil, which was a really crappy location, for it mounted it right out here, put it about two o'clock and I sanded the line before I put it down just to make sure I got a nice clean surface when you put these Things that they're new, that you have to spray on all right - it's okay, be very careful.

I kind of think about just a little bit out of the way a little play. Screener. We will importantly. I think that our problem is use leverage so use your hands.

My list they're twisted back down so stop this one should have pins, unlike the other one watch out for anxiety, don't cross it, it should go. I can still hear it out, ignore I'm probably not going to be the greatest way to do this. We're good! Okay, not overtighten, that's the Velva oil swine minimal loss in the system still has pressure in it. So we're gon na pull the strainer really quick, Raina's plug up.

I know it's like crap, so that strainers done I'm gon na go to Maidan and get another. There's always a star under pressure. I'd skied have another one working on real, quick I'll go get I spoil and bqk. I usually keeps trainers in here, but I'm all out, but I happen to have a valve that had that same style, a strainer.
So I pulled the strainer for now, but yeah. If you have your BQ kit, if you can leave some space and keep some strainers in there that way, you know if you're doing a hot swap like this, and you don't have time to clean it. You could just pop a new strainer in there, but I'll pick up a new one next time, I'm at the supply house - hey what do you know? We have such an pressure now. So what I did was this thing had low temp power heads with pressure limiting.

I said: had low temp expansion valves with pressure limiting power, heads or low temp, our heads that have the pressure limiting feature on and I put in medium temp pala heads, because really this shouldn't have been loaded simple and this doesn't get below 20 degrees. It should. I never had low temp power heads on it to begin with, and then on top of that, the pressure limiting power head. I get why they did that because it had a left or defrost and because it's a higher ten box it would be under a heavy load but anyways.

I eliminated that from the picture now remember. I did let some refrigerant out, so we are gon na have to put the refrigerant back into the system, because we are flashing on our sight glass. This system does have a head pressure control valve too, so we will make sure that we check the refrigerant level and the receiver to make sure that it has enough for the headmaster head pressure control valve once we're done charge. But it's like we're gon na here's.

My strainer, like a bug - oh there's, no, it's gon na be hard for you guys to see inside of it, but it's got chunks inside of it. It was doing its job. Someone before me previous company, before us, wasn't using proper refrigeration practices for here. So I gave the RAC a quick rinse, nothing crazy, just real quick.

We actually aren't flashy even after I put all that refrigerant back in we were flashing, so I'm thinking, maybe it was going off on bypass just because the rack was dirty. I'm gon na go ahead and clear the sight, glass and then add the remaining refrigerant for the winter charge and then like one thing after another here, so this thing keeps going off bypass. He keeps internally bypassing eyesight will disengage in an equalized, and this is an original go for compressor. I think that the compressor was weak and I think everything that I've been doing today is just adding to the problem.

They have a dirty condenser. This thing's been linking along, but because I took the pressure limiting power heads out. I think that the compressor was already going bad and the pressure limiting power heads is just sent over the because now we've actually got suction pressure, mind you it's only 37 degrees in the box, so you know 36, it's it's not like we're we're going crazy with The expansion valves I mean that's just a little bit - that's like a 12 degree operator TVs, so it's running like it should be, and it's hot outside, so it it'd be expected that we have almost 400 head pressure right now. It's uh yeah! It's right! It's just about a hundred.
I think this is a little inaccurate right now, so it's just about a hundred degrees, so we're a little bit high on the head pressure, but I think what's going on and I think that compressor is not pumping correctly. I think that that internal bypass is partially leaking. Mine is my theory here, because I can't my cycle is all of a sudden. It's just barely flashing, but it's flashing and I checked a temperature drop across my dryer.

It's not plugged up we're gon na try to pump it down at the temperature controller and see if it I'm gon na try to get through the weekend for this Friday afternoon. This professor tonight, the region that'd be great all right, so we tried to pump it down just satisfy the temp control. You can see so it's running, it's still got a cold. Suction right still has a hot discharge wine, but it's just internally by passive.

You can hear and what it does is when it hits about 410 psi. So there's a couple things I could do. I might be able to throw a mr. on here.

You keep the head pressure down for the weekend. Inevitably we have to change the compressor. It's just whether or not I want to change it right now. If I can keep the head pressure down, we could probably get away without having right so I've got it operating, but it's literally, I don't even know if I'm gon na make it I'm probably gon na, have to change it tomorrow.

Saturday morning, baby tonight we'll see the professor's about two hours away from me: nobody, local houses, so I'm gon na go pick it up yeah, so we're just going to leave the mister on there. It's running the box is actually down to temp right now, but it's just going bad so so I did not get my wish and I am changing this compressor. It's currently about six something on Friday night, so I just got the rotor lock, adapters, braised or soldered on or braised on use, 56 percent silver solder. I'm just cleaning up my welds now everything's, nice and clean.

I like to sand them. What I've done, for whatever reason the host city likes me looking pretty so, yes we're on all right. I really can't film too much because I'm trying to do the work and it's late at night, but I ended up having they didn't, have an inch and 1/8 rotor lock. So I got a 7/8, so I got a bushing two inch and 1/8 it'll be fine.

This valve we tried to use the existing valve, but it broke when we were trying to take it off. We're gon na go ahead and use the existing discharge valve. This fan cycle control broke off no big deal. I'm not worried about that.
So we'll fix that and yeah we're just trying to get it up and running. We got the dryer cut out, so I'm a little bit out of time. It's getting dark outside, but we're getting closer. I got the pressure control installed, the compressor wired up, I'm still going to check phase rotation, we're waiting, I'm going to get my suede, so we can finish the dryer everything's braised in we got to pull a vacuum and then to that we'll see seems like it Took forever but we got the vacuum pump running.

I just closed the gas balance. Last I checked it was at about 1,500 microns or just letting it run. I have like I'm 99 % sure this thing has other weeks in it. So I'm not confident that it's gon na pull a great vacuum, but we'll pull it as low as we can and then see how it holds system.

This big, I I wouldn't be the least bit surprised if we got leaves but, like I said, we'll see we are getting there so 917, so we made it under a thousand, that's a plus. So it's not everything. It's not as straight as I'd like it to be, but you can only do so much when it's by 8 or 9 o'clock at night. Now it is times like these that I do appreciate these big backing poses.

They really do make it go a lot faster and a lot smoother, especially when you're in a pressure bud. So we've still got to power this guy on charge it up, and then we got to make sure the phase rotation is correct, because this is a three-phase scroll so currently charging it right now it held a pretty good vacuum. It pulled down to about 600 microns. That's about all, I was going to wait for it held actually, but I can't wait any longer.

We're gon na get this guy going. So I just went ahead and opened it up and we're discharged as much liquid as we can into the receiver we're at six pounds. The total charge on this guy is twenty five point two pounds so we're gon na go ahead and weigh in the factory charge. They calculated that to be the right amount for the head pressure control valve with the line set length and everything.

So it's kind of nice on some of these refrigeration systems when they have that calculation for you. But if you ever do go through the process of figuring out the calculation, it's always good to write it down for the next guy. So that way, when it comes to something like this, they got what they need and they can just charge it up. Hopefully, everything will be good, so I couldn't really get it on film, but I started it up and it wasn't a sounding ride.

It was way under amps. It was running five amps and the compressor was making a funny sound. So that meant that the phase rotation was incorrect, so I switched to leads and now we're much better and we're pumping got a cold suction line. Coming back, we're right at amps right now, so we're gon na kind of throttle, the suction it's kind of drop.
The amps down a little bit, so we don't overload it we're gon na get this guy charged up. So it's going to take a little bit all right, we're about 13 amps. I think the run load is like 14. So we're doing good on that pressures are looking good.

I haven't been downstairs, but I imagine it's probably about 40 38 degrees somewhere in there. So that's yeah little to be expected because we're probably flooding a little bit a nice cold suction line coming back sight. Glass is clear: you put the factory charge back in so the sight glass cleared at 18 pounds and then we've build it up. What did I do? We went up to 25, so yeah we're good we're gon na make sure it comes down in temp, I'm going to shut the system off, shut everything off into a leak check, real, quick and then we're gon na come back and follow up by Monday or Tuesday.

Make sure all as well Saturday morning, I came back to the scene of the crime I just wanted to kind of. I don't know I was having a hard time sleep and thinking. I did something wrong or forgot to do something. So I just came back out here boxes down to temp.

It was actually satisfied when I got here watch it just turn on right now. I'm not gon na put my gauges on today, but we're running a clear sight. Glass everything looks good. I mean there's a few things.

You know drive me nuts, like the bracket for this pressure. Controlled fan, so it's not straight. The dryer is not a hundred percent straight, so it's kind of and stuff that goes. Let it go, but yeah we're gon na still be coming back, because I got to get a crankcase heater for this guy, the old one I couldn't get off and then also handcycle control program, the fan cycle control yeah other than that.

That's pretty much it! It's working customers happy, so I'm gon na go home and enjoy my Saturday and follow up with those other parts later wow that one really turned into a disaster. What was a simple call wall? What was kind of a simple call as a beer walkin that was icing up and then initially I just found that the power switch was off, but then the further I dug the more I unraveled found that there was electrical problems. Things were never hooked up from the very very beginning from day one and that restaurants been there since 2004. I think what a mess ended up, correcting that, like I mentioned in the video, I ended up changing the system over to an air defrost, because there was really no need for electric defrost again.

We still have to monitor to the system to make sure that my changes as far as the defrost strategy goes don't create a problem, but I really don't think that they are and, like I said, you know that coil temp never gets below 20 degrees. Really so there's no point in really having electric defrost, except for maybe being able to defrost really quickly, but at the same time they didn't have the proper limits which is hooked up inside that unit. So it was just kind of a disaster and then found that the system was running. The pressures too low found that we had power heads that were going bad and then, on top of that they were pressure limiting power heads which again is another problem, because that's not a low temp system.
So I corrected that and then that just unraveled the problem with the compressor so, like I said kind of in the video, I have a feeling that the compressor had been going bad for a while. But because it had the pressure limiting power heads, it was reducing the suction pressure, therefore reducing the load on the compressor. So I think that the the pressure limiting power heads changing those over to a medium temp which got it working properly, but then it overloaded the compressor and then on top of that we had a dirty condenser. It was just like one thing after another.

I think that that day altogether I started at 7 a.m. and I walked in the door at 11 p.m. and that seems excessive amount of time. But when you think about what I did, I unraveled a bunch of things there and then you have to throw in to the fact that I had to go, get a compressor that I was two hours in traffic.

Actually, no, I had three hours in travel time. An hour to go pick it up and then two actually three and a half hours about two and a half hours coming back. I did have another technician come out and help me when I was installing the compressor. I had an apprentice with me during the day, but you know he was just kind of helping me held the camera and then we were just kind of obviously explaining what I was doing and then, when I went to go change the compressor I had another technician.

Come out and go ahead and help me out by recovering all the gas. So when I got back with the new compressor, he had already recovered all the gas out of the system and had already started unbolting the compressor. And then that was kind of where the video started again but yeah, and then you know I got it all finished up and got it running little things happen, crank case, regular crank case heater went bad or I couldn't get it off. The the fan cycle switch broke, you know, that's just normal stuff, so I'll take care of that later.

But then you know I came home got home about 11 o'clock. I think something like that and immediately started to second-guess myself and doubt myself and - and I slept, but I didn't sleep really well, because I kept thinking did I did I check the temperature controller. Did I make sure that we didn't leave it set wrong? Did I do this? Did I do that? You know I was worried that there was gon na be a leak so 6:30. In the morning I was pretty much awake kind of tossing and turning - and I just I couldn't deal with it so I jumped up - got dressed and went back out to the job site, it's about half hour from my house just because I just needed to know.
I didn't want it to be a service call, and I wanted the customer to be taken care of that's the kind of stuff that drives me nuts. I have many sleepless nights. Thinking did I turn that on. Did I check this out? Do I wish that on other people? Yes, and no, because that does make you a technician that that cares about what you're doing, but it also sucks, because you lose sleep over things like that, and sometimes you lose sleep over nothing like last night.

I was just worried that I did something wrong and went out there and everything was fine, but you know I do think that that's a good value, because that that means that I care you know and then I honestly do it wasn't. Just I mean it is about making money we're in business to make money, but it's also about delivering on what I promised and making sure that I can do my job properly and take care of the customer and that the customers happy. Yes, this is gon na cost, the customer a lot of money. We had to overtime, labor, all kinds of stuff right, it's gon na be a very, very big bill, but it's taken care of.

Do you think that the previous company could have done this job properly? Do you think it would have worked out? Do you think they would have lost be ourselves? You know that this customer didn't lose any single beer sales. I had that system running and operating and I'm not trying to gloat and make myself look better. I'm just trying to say I care to the point that simple things like when when I diagnose the compressor was bad and when I went to go pick it up, I put the mr. on there.

So that way I dropped the head pressure, so it ran the entire time I was going, you know and the customer was like dude we never lost product. We never had to stop beer sales because I was concerned about their sales. I want to make sure that they're happy. I want them to realize that I have their best interests in mind.

You know, and yes, it is about making money, but at the same time, it's about making sure that that my reputation is good, that the customers taken care of and that they get what they want from me. Okay, so it's very important. I think that that's something that we're lacking right now. I think that we're definitely lacking with a lot of people in the trade that that you know they just don't have that passion they just don't have that that want to make sure that things are a hundred percent.

You know they don't have that drive. I'm not saying everybody is that way and I'm not trying to bash everybody in the industry, but I'm just saying take a little bit of time and think about it be concerned about the customer. You know. Yes, the money is gon na, be there you're gon na make the money there's a lot of things to be worried about in this trade.

But you know if you can just start with doing a good job, delivering on what you promised. Make sure that you do to the best of your abilities the best of your company's abilities? You know your reputation is gon na make you succeed and I'm not saying I'm the most successful person in the world. I'm not we struggle as a business, just like everybody else, but there's one thing that I don't have to worry about. I don't have to have a sleepless night because I ripped someone off because I never do.
In fact, I probably lose more money because I'm worried about oh does that's that bill seems excessive, so I shave hours off of it and different things like that. I constantly do that so anyways, I'm going off on a rant now. I really appreciate you guys taking the time to watch these videos. Let me know what you think down in the comments.

Send me an email hv, you see our videos at gmail.com and we will catch you guys on the next one. Okay.

    One observation. Exercise caution when converting an electric defrost evaporator to air defrost in a cooler system. A lot of beer coolers are designed with a wide TD (Up to 15 DegF) and are kept at 33 degF to 35 degF. If you eliminate the heaters on an evaporator in a system designed this way you might experience excessive frost problems because of this. This also applies to other applications like Carcass Hanging (pull-down) rooms were Electric Defrost is preferred on the design aspect because of the high humidity conditions expected and the 31 degF temp requirement in the room (As per ASHRAE refrigeration handbook). A technician might believe that because the system is a "cooler" electric defrost is not needed and that is not always the case. In this video, the technician made a good explanation of the problems he might experience by doing the change and was aware that the room was not being kept lower than 37 degF.

    Caring for your money source is good practice. When the client sees that he will use you again. I find it interesting how you determine the faults and importantly, why they failed. I was a QC inspector and i applied the positive negative positive culture. REVEAL THE GOOD. EXPOSE THE BAD. CONTINUALLY IMPROVE. Thank you again. Are you in Kanata ?

    Chris, it may work for you to have a written punch list to check off before you leave a job. I have done that a lot where I think I forgot something and go back to see it was all done.

    Never knew this was such complex matter!

  10. Avataaar/Circle Created with python_avatars Robert Miller says:

    Probably originally a freezer, were the old Power heads ZP charges? Pressure limiting? I hate those. I say this based on all the electric defrost and Z power heads you found. Lots of places decide later they would rather have a cooler, OR, get sold electric defrost to run a really cold beer room. Then some person looks at the coil chart and decides to put in the low temp valve.

    Usually you can't get anything fixed correctly with a fist full of fifties. You are awesome and unique. A person of honor & integrity.

  14. Avataaar/Circle Created with python_avatars Ashley Jarvis says:

    Totally agree, take pride in your working practice and escalate concerns/estimate. I work in a different industry โ€œsoftware engineeringโ€ and see the same problem – I wouldnโ€™t quite say it these words, but talking to a client i would often say โ€œ You can patch it with this, and youโ€™ll be back working/in business , but longer term X Y Z will need to be doneโ€. Thereโ€™s often a server/network/capacity/housekeeping issue underlying it – usually housekeeping. Service area Orleans??

    I have the same OCD, so I take pictures when I leave a job, even when I lock the door to leave, then I can sleep.

  16. Avataaar/Circle Created with python_avatars Re Argiro says:

    Chris, everything was interesting, but,! Never take of any time off a bill of a client if you did everything right. We use to do that and thatโ€™s what brought us nearly out of business. Today we take our time to talk about the situation and the cost with our costumers. We prefer to discuss this before, as some client can afford a repair of 10+ hours and the next client canโ€™t and is up to a other solution.

    I'm a small business owner and technician in Australia, and I feel you. I know all about sleepless nights because even the best technicians, still can second guess themselves, and like you said, it's because we care.
    Thanks for you great coverage on HVACR. It's better then watching a movie to us thirst for knowledge Technicians. Cheers.

    I HATE LOW PROFILE EVAPORATORS!!!!!!!!

  19. Avataaar/Circle Created with python_avatars Locutus von Borg says:

    shouldnt that be normal for companies like ur? i mean, the best intrest, should be the intrest of the customer. cause when something else needs to be fixed, they probably call for the guy who also cared for them, even if it costs more. at least i tick that way

    Dude! I love how you explain what your doing and why! And what you may see as a rant at the end, I see as a tech who is committed to his craft! Also, I can relate to the OCD! Really Appreciate ALL your videos!!

    Thanks for the video, you do good work and as I'm still learning it's really helpful to see real world examples of situations that I wouldn't normally find myself in Service area Ottawa??

    Electrical work, and proper diagnosis very important. Understanding wiring diagrams, but more important basic knowledge of electricity, all 80 percent of Refrigeration, and Air condition are electrical related, how I know because I put time in electrical trouble shooting. proper wiring, and buying good books in this field. This guy is very good, a season Pro,

  27. Avataaar/Circle Created with python_avatars Leandro C says:

    Chris, you have the business mindset I wish all companies in general have. Iโ€™ll give an example. Iโ€™m in the IT world. In IT it once was quality over quantity. Companies took time to quality test and release reliable products. Somewhere along the line a new generation of mindset entered into the high ranks of IT and changed it to quantity over quality. I manage several different kinds of software that once used to be solid. Today they are half baked buggy as hell pieces of crap. Support wasnโ€™t just a bunch of scripted robots it was people who actually cared. These same people switched it to annoying scripted robotic sounding humans who donโ€™t give a damn about the customer. Same knuckle heads decided to outsource everything. Companies that all had quality in house it departments no outsource to expendable cheap sub contractors. And some how the industry welcomed this crap. Instead of rejecting it. Iโ€™m a sub contractor myself because I canโ€™t find a position thatโ€™s permanent anymore now that 99% of all IT is out sourced. But still I hold my dignity and go against fast judgement and perform quality work against my upper managements wishes to provide numbers over quality. Hell if all ceos where in your same mindset Corp America would 100 times better. Not saying this negatively just expressing my opinion. I really wish the age of quality would return and fix the mess the new generation has caused.

    HVACR, I don't know if you're reading this, but I've seen a lot of "previous companies" jobs done, and billed the customer. Worst thing is, that I've found the same thing from our previous employees, and now we have to do some damage control, to make customer happy. I've used to be an electrician, nowadays fire safety professional. Keep up the good work, and greetings from Finland.

    and now you know medium temp heads do not go with low temp compressor Are you in Orleans ?

  41. Avataaar/Circle Created with python_avatars Mario Perez says:

    the big picture is that you had a 2hour and a 1.5 defrost with no limit burning wires,put it back on line do a test run then make a decision.
