Before the video starts, do me a favor. At the end of the video, there's a couple little outakes. Check them out! Okay, when I'm editing these videos, there's a crap ton of crutch words that I have to take out. All right.

Okay, yeah, just it's funny. I try not to say them. but I say them all the time. So check out the end of the video you'll see also if you guys are interested in supporting the channel.

We just got a restock of a bunch of different stuff. The hats are the number one sellers. Beanies We have cuffed beanies. We have non-cuffed beanies.

We have, uh, multiple different designs on the hats. You have the dad hats for the bald guys that have really short foreheads. That doesn't apply to me because my forehead is huge. We have the flat bill hats.

This is a um snapback hat but it's also Flex fit. Okay, all of my hats have a black under Bill That's really important for me because when you're working, there's nothing worse than having the the gray or the white under Bill and your fingerprints get all over it. And then the most popular hat is the uh. this one is a breathable material.

but it's not a trucker hat. It's hard to explain, but I can see light through it. it. it's a flex fit black under Bill and just a standard bill on the front just says Hvacr If you're interested, check it out on my website Hvacr Videos.com Let's get on with the video.

This video is brought to you by Sportland Quality, integrity and tradition. Well guess what? I am back. This is the one that uh, we had plugged up filters on two bad compressors and uh, when I changed the compressor, there was no oil in the compressor. the old one that I autopsied.

Oh boy. but guess what? I'm not back here for this one I'm back here for their bar AC Okay, so this is their kitchen AC This right here is their dining room AC and the bar AC is actually over here. this one right here. but guess what it said.

it keeps tripping the main circuit breaker I Walked in the door and I saw that it was in the tripped position. So yeah, um, we. uh I don't doubt that the filters on this unit are going to be plugged solid. We just had a tropical storm come through about a week and a half two weeks ago probably two weeks ago now and I was like why aren't they calling me because I know that this whole Coachella Valley which I have to say right now I do not live in the Coachella Valley This is not my normal service area I Come out here for a few specific customers and that's it I'm 2 hours away with my normal service area.

okay cuz I get emails and comments and stuff all the time I don't live out here I Don't work out here on the regular, just service a few customers out in this area, but the entire Coachella Valley got destroyed from this tropical storm. Um, massive flooding, sandstorms, craziness, right? The res, res, or remnants looks like I think I cleaned most of this up last time. You can still see the drains are all just discombobulated. Don't know why, whatever.
That's a whole another problem for another day. But this AC's tripping the breaker. So let's get my tools out and we're going to figure out why. All right I Opened up the electrical section and right off the bat, this is what I see right here.

that's not good. So if that continued to run like that, this is a three-phase compressor. It would have eventually single phased because it's three phase and it's running off of two phases when a wire Burns off. But we don't know if that's the only problem.

So let's uh, contactor looks to be stuck in the mid position. So I do power turned off at the breaker downstairs. We're going to turn off power right here and we are going to start testing for continuity to ground to see what is potentially shorted. Look at these compressors.

just like on the other unit, you can see that they've been flooding back for a significant amount of time. You can see that they're almost calcified like so yeah, that's not going to be good before. I Go any further. I Also brought filters air filters out with me because I knew these were going to be plugged up and they are are completely set or just completely impacted with sand.

So I'm actually going to change all the air filters first on all the AC's before they start getting customers in the building. Got new filters and every AC dated. the last ones were from 2 months ago and they were just hammered. Now this customer does do routine maintenance quarterly so their maintenance is about due.

but filters just plug up because of all these sandstorms they have. I mean we clean this unit it out 2 months ago. look at that as best as we could. We cleaned it out so the customer knows that whenever we change the filters I can't get all the sand out of there.

it's going to freaking blast downstairs so they're privy to that. Um, pulley has some slight wear to it, but it's not bad. So I think we're good on that? I'm going to put all the panels back on and we're going to finish our troubleshooting. So start starting with the compressor that had the burnt wire.

I've got my meter on continuity, the tone feature okay, and we've got one leg clamp to ground and we are testing from one terminal and we have a direct short to ground. That means there's an electrical path from the electrical wiring in this compressor to the copper lines which is grounding the unit out. This is a grounded compressor that has burnt the refrigerant now I Know it's going to be a severe burn because the customer told me that every time they tripped or reset the breaker, it trips again. So they've been tripping it for a while, causing this things to constantly short.

constantly short, constantly short, and it just destroys the inside of that compressor. All right. So we know this one's dead. I'm going to go ahead and isolate this, tape it off, pull all the wires off the bottom of the contactor, and then we'll move on and check the rest of them.
So what I did was I removed all the wires. Okay, they're basically right here I Pulled them all the way back to this spot right here. pull the wires out and uh, just took them out of picture. That way nobody can mess with them so there's no power going to the top or the bottom of that contactor besides control voltage of which I'll disconnect the control voltage too cuz we might blow a low voltage Transformer if it won't pull in or something.

Um, this guy's disconnected. This compressor is bad. Uh, 61,000 BTUs So this one right here and this one right here. we need to test so first and formost most okay.

we're getting continuity to ground so I've confirmed my ground is a good source. So now I'm going from each compressor, lead to ground on the remaining two compressors and we're getting nothing and then I Go to this right here. testing from this to ground, seeing if there's any other shorts anywhere else and there's nothing. I've got no more shorts to ground.

Don't see any other problems as of yet. So what I'm going to do is: uh, we're going to go downstairs and turn the main breaker on. Then we're going to come up here and check power at the disconnect switch I'm going to bring my air blower up and I'm going to blow this electrical section out real quick and then we're going to attempt to start this guy up and see if we can get the remaining two compressors operating for now. I Went and grabbed a face mask for this one cuz it's going to be nasty.

This sand out here is not not that any. Sand's really healthy, but this stuff's not healthy because a lot of it can come from. uh, the evaporating water in the salt and sea. and uh, there's a lot of chemicals in there because of agricultural runoff and stuff.

and so there's been lots of cancers and different things linked to the blowing dust from the salt and sea, so whenever you can, you want to mask up All right. We got our main disconnect switch right here. Let's see what we got going on as far as electrical. All right.

1 to two 21, 2 to 3 21 and then let's get one to three 212 So we have three-phase power coming into this disconnect switch 1 two, three please don't blow up. Vfd has power standing to the side. It's ramping up so indoor blower motor's running so far. we got LEDs on on the little second two-stage board.

Let's he these compressors start up and see what happens when they start up. Both compressors turned on at the same time. They really should stage those. Look like we got some sort of short cycle there I don't know what that was about I Better gauge up on this guy.

You saw how they like, turned off both of them, then turned back on. This thing only has free stats and high pressure controls. It doesn't have low pressure controls so maybe it went off on high. Head better.
Uh, hop up here and see if the condenser fan motors are working. All three condenser fan motors are working, so that's a good sign. Condenser is kind of dirty. I'm going to give it a a I'm going to take the air blower to it I was going to say the wrong phrase but I'm going to take the air blower to it.

You guys can figure out what I was going to say and then I held myself off on see what this does. Woo cleaning a condenser coil with a leaf flower. Look at that all into the street. All right! I'm currently probing up on the system and I've talked about this before, but when you are using digital tools, whether it be probes or digital manifold I don't care what brand it is, even analog tools like a compound gauge manifold, you always want to make sure that your stuff is zeroed out.

if you look right here. this highpressure probe says 1.5 PSI Now that may nice. may not seem like a lot, but when you're calculating different things, you don't want something right there like that negative 1.5 PSI when it's not connected to anything, throwing you off when you're trying to dial in a critical charge on something, so you always want to make sure that your tools are zeroed out. Now we can have a conversation about how over time these things start to drift and they constantly I have some that Don't Drift at all and then some that do so honestly I have so many of them it's kind of hard to keep track of which ones are doing it.

I guess I should start marking them so I can take them in and get them replaced or something but always want want to make sure you're checking that before you, uh, apply your gauges to things. That's why it's so important to not put your gauges on before you turn everything on and zero all your probes out. All right now. this guy's been running for a little bit while I've been putting on the probes and everything circuit.

One is far as normal system vitals. Superheat doesn't look bad. Let's see it's a fixed Orphus metering device. We're calling for 5 of superheat currently.

Right now we have eight that's fine. Sub cooling is I'm not too concerned with that. Let's go ahead and change over to the second stage second stage. There we go.

We've got 3 superheat and 10 subcooling 4 super. It's kind of ranging as it's bringing the building temperature down. Okay, now even though this has three circuits, we know the third stage is bad. So I have it profiled as just a 12ton two 6 ton compressors.

We have three 6 ton compressors basically, so this should be an 18 ton. Um yeah, 18 tons. so 210,000 BTUs on the model number. So they do some weird stuff with the compressors though cuz they put 61,000 BTU compressors.

but it's something they do with the condenser and evaporator sizing that gets them to the full 18 tons. Um, okay so approach temperature I mean I don't see anything crazy with that temperature split across the unit is you know, 8 9. It's going to be that way because um, we're missing a compressor right? so not going to get much more on that uh delivered capacity Seems like it's out of whack on that one. but I think it's GNA be because right now we're running with massively High airflow.
but we're only using two of the compressors. So yeah, I mean these things are doing everything that they can. You know, being this guy being down all the conit fan motors are running. but yeah, see, like the Vfd you guys can't see but it says 60 HZ it's it's programmed for 60 HZ Really, it should be running at lower speed.

um I can actually probably get it to run at lower speed and get a better temperature differential if I disconnect Y 2 which I'm going to try that and see if that'll it should slow down. The blower doing that did slow down the blower. Uh, it also dropped my superheat which is expected. so it's currently at 2 on the first stage.

We'll give it some time and 2 on the second stage. um. temperature split went up because we're moving the air slower through the evaporator coil. so that's actually good.

Whether or not I'm going to leave it this way, we'll have to see. um I mean it's doing everything that it can. These other two compressors are working. Uh, we slowed down to 40 Hertz I Just taped off the Y2 wire cuz the Y2 just controls that third stage anyways.

um H Okay, well I'm going to let this run for a little bit. I'm going to test the crank case heaters, make sure those are working and just kind of go through everything on this guy. all right. at this point, this thing's doing everything they can I'm going to uh, it's got a really low load inside the building right now cuz I'm really jump.

you know, ramping them down. So um, we're going to, uh, give them a quote to replace this compressor right here. Um, it's going to be a fun chore. Yeah, it's going to be a nasty one.

Not a lot of room now that they have three dryers. The last unit had two 7 and 1/2 ton compressors. This one has, uh, 3 six tons so it's kind of crammed in there. But we'll figure it out and that's it.

Um, everything else seems to be working so we'll just tell the customer to keep an eye on it until they approve this quote and we are back today. So we are going to go ahead and replace this compressor right here. so it's a process you can see. We don't have power up here so made our own cheater cord.

Um, recover the charge, change the dryer. You know the drill. Let's get to it. This restaurant's just horrendous.

We pulled this out real quick. These were just changed. Like you wonder why compressors are going bad in these things. That's insane.

We've got the gas recovered out of this guy. it's now open to. Atmosphere Um, we're going to get the compressor pulled out. We got to put a new dryer.
We're going to do the ball valve thing with the big 30 cubic in dryer. But what we are going to do on this one because of the problem I ran into on the last one is we are going to slightly pressurize this with Nitro Um, it is a burn right? so it's grounded so I got a new piston just in case we're going to pull the chat lift connection. make sure the Piston's not plugged. We'll probably just swap it out.

but we're also going to drill this suction line right in the bottom and we're going to pressurize it slightly to see if we can push any oil out because I suspect that the compressor's oil is all stuck in the evaporator. That's my assumption. We'll definitely blow the condenser out too. It is a bit scary doing this, but just going slow trying to make sure the shavings all fall out.

Okay, hopes that there's no other shavings going in. Well, there's no oil dripping out as it is. but once we get some nitrogen in here, we'll hope that we'll let back Blow from the liquid line over. So that way potentially it blows it this way.

That's the idea. The idea here is that we're going to take nitrogen, slightly pressurize the liquid line. we still have everything else capped. And because I drilled the bot of this right here.

In theory, if there is oil in there, slight pressure should start to push it out of that hole. That's the idea. So that's what we're going to try right now. Go ahead.

so far nothing. Okay, well, maybe we don't have an oil logy VAP and I don't even hear it either. Interesting. Normally you can hear it slurping around in there and I'm not hearing anything.

All right. Well, we know that that's probably not our problem, so that's a good sign. It could be in the condenser though too, so we'll definitely have to back blow that way. Went ahead and sanded this up.

I Got will over here taking the compressor out right now. I'll go ahead and get this uh chat lift connector right here. Pulled off and we'll have a look at the inside of that piston. uh I did get a little bit of nastiness blowing out in there just a little bit so we you know this is a ground for sure.

So but yeah, I didn't even hear like oil slurping around with the air, so that's kind of a good sign. I Guess now this is all just precautionary because we had a grounded compressor I decided to pull the Piston too. Okay, the Piston doesn't look bad, but we're going to change it. We have a new one.

It's not a big deal at all. So we've got a new connector and everything. so we're going to grab this little guy right here. Get in there.

it's a little wire piano wire thing. We'll pull it out and slap the new one in, then put the new uh Teflon ring in there too. Pulled the old piston out. Nothing too crazy, just a little dirty.

But again, it's cheap. insurance on something like this. so we got a new Teflon ring in there. We're going to put a little bit of this Nyog blue on there, just right on the Teflon ring so I'll put a little bit on there and then just a little bit on the chat lift connection right up here in the top so that way it can spin really well.
From past experience, the last compressor we did on that unit over there remember it had no oil in it. So as we're unsweating things, we're watching for flameouts because flameouts are an indication of Trapped oil. So when we popped the dryer, we were just kind of watching, but we didn't see any signs of it so far. I Don't doubt that there's going to be a little bit of oil right here.

That's pretty normal. Um, a lot of people say like oh my gosh, that's a trap that should never be there. No. I mean the the concept of a trap is that it speeds up refrigerant velocity.

So this little in or trap right here actually just speeds up the refrigerant velocity. Yeah, there's going to be a little bit of oil sitting in there typically, but it's going to help to speed it up and grab oil oil from the system. So um, yeah, we're going to get that dryer pulled out and then we got. The one we're putting in is massively oversized because this is a burnout, So Will came over here and patched this one up so we're good on that.

That should be good. And then, uh. we were trying to remove the filter dryer over here but the top of the thing kept burning so we got the Viper heat blanket in there now to try to protect everything so that way he could really get in there and pull that dryer out. Still got a little bit on the back of the unit, but the heat blanket should help a little bit.

There we go. Nice. That heat blanket is pretty cool. does a good job protecting everything.

Now you can get it wet or not. We didn't get it wet in this case, but it's perfect. Make life easy. We went ahead and made a little setup over here with the dryer that we can get it brazed in over over here.

We already test fit everything with the ball valves, making sure that the shut offs the pressure ports are on the inside so that way you can isolate it, recover the charge from here, swap out the dryer, gave ourselves plenty of room here in case later You need to cut it so that way you can sweat in a new dryer and have a little bit of space. So Will's going to get that sweat together and then uh, we're going to come over here and pull this compressor out of here cuz it's ready to come out Now we're just going to give the condenser a quick blast. Right now, we have our Cup right there. pull it down a little bit where we can see it I Don't feel any oil coming out of the condenser either and usually again on a tube and fin condenser, you would feel the oil gargling in there.

Um, so we're going to tip over that compressor and pour the oil out and just find out. But all sign lead to the fact that that compressor should still have its oil in it. and now we're ready. So we got a spoiling catchall with an HH core which is the high wax content removal.
As you get a burnout, the insulation, the plastic coating on the windings of the compressor can start floating through the system. and the HH cores are specifically designed to remove that wax. they have a much more fine, uh, particulate removal I guess is the right way to say it. Um, so that definitely helps the systems.

I used to think H H me high acid, but it actually doesn't. Uh, the normal sporin catchall core has amazing acid removal as it stands. So this right here is really just for the wax removal. It's not really a lack of oil problem because there's oil in there now whether or not that's the 1.6 L I don't know about that, there's still oil left in it, but that's certainly enough oil for this compressor to run.

I Was looking thinking that it was like the other one where it was going to be completely out of of oil. and that's not the case. So I'm wondering what the cause of death was here. We're going to have to cut this guy open to figure it out.

Um, plugged up air filters would cause low suction pressure, low compressor cooling High ambient temperatures I guess could cause this compressor to bake. We also know that this guy was more than likely it's a piston, so more than likely it was flooding back. flooding with liquid, but flooding on this typically would. Well, it could have been just one time.

We could have just blown the compressor apart inside. It's hard to say we'll have to open it up, but lack of oil? I Don't think that's really the problem. Um, if I had to guess, those cups are what? probably 16 o cups. So that one's about half full, that one's 3/4 full, that one's a third full.

I Mean there's quite a bit of oil in there and I know there's still going to be more in the compressor. We went to lunch. the unit's been running and we had it in a vacuum so we just shut off the vacuum pump, moved it over to here. Um, we're currently changing the contactor now.

We field modified this unit and we're adding a low pressure control which it didn't have before and we're putting a time delay relay for short cycle protection. So we're changing the contactor wiring in the relay and then we're going to weigh in the charge and hopefully start it up here in just a few minutes. We've got just about 4 lbs of gas in it at takes 5.8 lb or 5 lb 8 oz. so we got to turn it on.

Now we're getting probed up. Um I'm going to have to jump this out because it's satisfied. So I'm going to jump it out real quick. All right, our system is running.

We have it all jumped out. We are currently waiting for this time delay that we installed. the short cycle delay. It's currently holding voltage out.

it's 180c timer. so when that closes, our compressor should turn on and we'll be able to finish charging it. We were only be able to get right about four pounds of gas in. it takes 5 lb 8 O so we're just waiting for that delay.
Then we're probing up so we can check out the rest of the system. The other thing I thought about too is we want to make sure we're going to check these other two contactors see what kind of shape those are in too. Being that it wasn't an oil failure with the compressor, it starts to make me wonder if it was just a contactor failure. we pulled these other ones.

I mean other than that one being a little darker, but We looked up into the points. it doesn't look bad so we don't really see anything wrong with the other contactors, so we're going to let those go, put the covers back on and then we're ready to evaluate everything now. We just got the air probes in the unit so we're going to turn it back on right? This timer wasn't working. This was one that I had in my truck I don't think it was used, but who knows.

So we I sent someone to go get that. We pulled it out of the picture for now, but we'll put it back in so that's just an anti-short Side Cycle timer. So if the low pressure cuts off that way, it doesn't just run on and off based on the low pressure control. If this opens, that timer starts running it, you know, slows down the short cycling basically.

Um, so in the the meantime, I've got everything running and we're checking the charge. Okay, so if we come over here, this is a fixed Orphus metering device. It has a piston. Uh, you can see that we're running about 5 superheat I Believe that's what we're calling for based on the indoor ambient conditions.

about 5. Okay, so first stage looks to be pretty good. Second stage looks to be about the same. 6 superheat somewhere in there.

Okay. Third stage however, has really high superheat. Okay, now we weighed in the factory charge, but what we didn't account for yet is that massively oversized dryer that has a lot more internal volume. Okay, so we need to go ahead and adjust the charge.

Now, we're going to do it based off of superheat. So we're going to get us to about 6 superheat by adding charge carefully. This is a Micr channel system, so a little bit goes a long way with this guy. so you can see we're basically right at 5.8 lb.

Um, adding just a little bit at a time, metering it in through the ball valve, and giving it plenty of time to stabilize because it's really easy to overcharge a Micr channel. Really, really easy. So I'm going to keep letting that thing run for a bit, adding charge a little bit until we get that number dialed in a little bit more. I added a couple ounces, actually about 8 9 o something like that.

I got my superheat to about 6. That's about as close as I want to go. Um, let's go through it. So first stage, we're actually running low superheat.

now. keep in mind I have a jump out so we have a low load in the building so that is going to affect things okay, but it's kind of coming back up. Uh, sub cooling about 6 Second stage? Give it a second, it's running right around 5 superheat 4.64 right in there. Kind of doing the same thing because of the low load 8 subcooling 9 sub cooling.
Third stage: give it a second right at about 6 superheat 9 sub coin so that's pretty good. Everything's running like it should be. okay. Um, let's go ahead and scroll on over.

Uh, Outdoor air is about 83. um, return and Supply So we have a really high temp split. now. this unit guaranteed has undersized duct work.

It's a typical package unit at a restaurant, so that's going to equate to why we have such a high temp differential there. So this thing's kind of doing everything it can. Um, now last thing I want to check is let's come on over here. Go to our probes probe manager.

So if we scroll right on down here, high pressure Three high pressure 4 Notice there's only three compressors. What I did was I put a pressure Probe on each side of the liquid line filter dryer so we can see pressure drop. Okay, so 340 34.1 Basically cuz it's 34.7 and 343 so we have about a 2 PSI pressure drop across that liquid line filter dryer. Okay, so we know that for future reference.

Um, we can also do temp checks across it, but that's that's good to know. Okay, uh, we see anything 3 to five and we start questioning whether or not we need to change it. And that's why I put ball valves here because this thing is, uh, was a burn we put in the HH core. We put these ball valves on so it' be easy to change this filter dryer after the fact without having to recover the entire charge.

Okay, so this unit is back and running I Still need to cut open the compressor to see what failed inside of it I'm kind of leaning towards maybe it was a contactor failure. um, cuz the initial thing was the burnt contactor but it could have damage too though from the plugged up filter dryers, right? So who knows. Um I'm going to goe and take my jumper off and like I said, take all my probes off and start cleaning up. I Got another tech coming back with the delay timer and then we'll get that put on there and then that's it.

We'll give the keys to the customer and tell them to keep an eye on it. Come on! coming up to this one I Thought that we were going to run into the situation where we ran out of oil again like in the last Uh package unit Compressor replacement when I got it back to the shop I cut it open and I was like dude it was bone dry like oh my gosh so that package unit um they still haven't approved me to dig into that further on the other one. But regardless, when I came up to this one, we had again plugged up filters. okay and uh, the initial service call was back in September and the replacement just happened the first: I think November 1 first.

Okay, so it been 2 months. it took him a while to approve that quote and the air filters had already plugged up again. So in the very first clip I changed the air filters cuz they were plugged. second clip two months later, they were plugged again.
That's what we're talking about with this sand. It's just insane. It'll just blow my mind that those air filters can plug up that fast in that short period of time now. Uh, we went through and again we changed the compressor.

Uh, you guys saw in the beginning how I isolated the the bad compressor so that way the unit could work. In the meantime, we came back out had a couple guys with me, they changed the compressor I was more or less doing paperwork and supervising kind of as the day went on. So I really didn't do a whole lot of work, just drilled the evaporator and let them do pretty much everything. but um, the uh, the compressor.

You know we were a little worried that maybe we were going to have the oil problem. so that's why I drilled the the the suction line header going back to the compressor. Still nothing. We blew it out with nitrogen, blew the condenser out with nitrogen.

no problem. Then we poured the oil out. now. I never measured it, but there was a lot of oil in that thing so it wasn't a lack of oil.

I'm really thinking I haven't cut the compressor open yet, but I'm really thinking that the problem was was just that failed contactor I think the contactor probably got sand in it or something. burn a leg, burnt the wire. who knows. Loose connection, something like that.

and I'm pretty sure it just single phased the compressor and just damaged it internally. It could have been. You know, something weird with liquid refrigerant coming back because we know what? the plug filters, uh, on these units. These are like Budget model Linux units so they only have a freeze stat from the factory and a high press control.

no low pressure controls, which we solve that problem on the third stage by adding the low pressure control and the delay timer. So that way you're not getting the onof of the low pressure control. but we basically did everything that we could to make sure the system was operating properly. I Like the idea of putting in the ball valves when I can we put the massively oversized filter dryer.

We obviously had to compensate by adding refrigerant to the system for that. Okay, and I showed. and that's so important to understand. We weighed in the factory charge and then it was still had really high superheat and was low on charge.

And that was because we have a large capacity filter dryer. Um, I believe the original filter dryer was an 8 cubic inch and we went to a 30 cubic inch filter dryer. So it's huge right? So big. Big difference.

So I had to add like eight or nine ounces of refrigerant I think is what it was. So we did that system's back up and running and everything was good. It's been about I don't know 3 4 days since we did that compressor replacement. uh probably 2 days actually cuz today's the 4th I think we did it on the 1.
um or maybe we did it on Halloween I don't remember I can't remember no I think we did it on the first. So anyways um but yeah everything's back up and running. We did the best we could. uh I do have the compressor so I will be uh at some point.

autopsy in that I'm sure I'll make a video about that. Um, but yeah, that's it I really appreciate you making it to the end of the video.

    Alright, Great Work!

    That sand is unbelievable! Here in Chicago we don’t have a sand problem, in some areas it’s the random bullet holes that wrecks the package units. Are you in Nepean ?

  3. Avataaar/Circle Created with python_avatars imark7777777 says:

    All right

  4. Avataaar/Circle Created with python_avatars Danny says:

    Could you have used a flare filter instead of a soldered in this situation. Thanks.

  5. Avataaar/Circle Created with python_avatars Jon Vickery says:

    I love the way that you go the extra mile and check for all possible problems to save a call back. Well worth the time.

    One thing I'm sure of…this video was alright.

  7. Avataaar/Circle Created with python_avatars Henry Flores says:

    I sneezed every time sand blew out. I started in the hvac-r trade and transition to steam engineer. Thank you for your videos. Sometimes I miss being on the rooftops troubleshooting units.

    The Load of Knowledge in ur Head 2 du this kind of job has 2 b ASTRONOMICAL !!
    LOL'S
    It's very Impressive how u make the jobs look so easy even with the Help, Apprentices ?
    Anyhooo, luv the Channel .

    Alright, another fine video! One question, why are the cups used to collect the oil wrapped in electrical tape?

  10. Avataaar/Circle Created with python_avatars Wholio says:

    ALRIGHT Mr. Coke nose…lol..I heard you flush out with nitro. What do you think of rx11?

  11. Avataaar/Circle Created with python_avatars Christopher Gonzales says:

    We all know

  12. Avataaar/Circle Created with python_avatars Christopher Gonzales says:

    Man it's probably a phased out contactor

  13. Avataaar/Circle Created with python_avatars Jake Jolley says:

    The alright outro was GOLD 😂😂

  14. Avataaar/Circle Created with python_avatars Venturi Life says:

    We take these units for granted, but they're everywhere and quite complex systems internally.

  15. Avataaar/Circle Created with python_avatars Electrician TS79 says:

    Wow, 61000 BTU per compressor. That's massive! Lol. And I thought a 24000 BTU unit was big….. Service area Barrhaven??

  16. Avataaar/Circle Created with python_avatars Major Tom says:

    Coke nose. That caught me off guard lol. Im having that same issue

  17. Avataaar/Circle Created with python_avatars A Wilson says:

    It sounds like the Restaurant Manager needs to go up and check all the A/C Filters weekly and call for new ones every 3-4 weeks (or as needed) based on how much sand is in them… Service area Ottawa??

  18. Avataaar/Circle Created with python_avatars A Wilson says:

    Even if the sand/dust was chemically clean, breathing it in is still an EXTREMELY bad thing to do as the fine particles can get all the way down into your lungs, causing scarring and eventually Lung Cancer…

    ALWAYS wear a mask when doing something that causes flying dust (sanding, grinding, Painting etc.)…

  19. Avataaar/Circle Created with python_avatars Joel Moe says:

    just an interested bystander but thanks for the vids, always interesting 👌🍻
    "alright alright alright!" and coke nose, lol (mo-guy problems, i feel ya)

  20. Avataaar/Circle Created with python_avatars Strohmmy says:

    question for the commercial guys… do you often have to set up a ladder or is there usually a built in ladder either in the building with a hatch somewhere or on the outside? Justa curious resi guy wanting to make the swap

  21. Avataaar/Circle Created with python_avatars parochial2356 says:

    "Customers been tripping…" 😆 Are you in Ottawa ?

  22. Avataaar/Circle Created with python_avatars Ken Napier says:

    Out of curiosity, do bring the dust problem up with the customer and recommend monthly filter changes?

  23. Avataaar/Circle Created with python_avatars Liam says:

    fine abrasive particles vs anything mech or electro-mechanical, what could go wrong? ⚡ Are you in Orleans ?

  24. Avataaar/Circle Created with python_avatars EverythingisFire says:

    Man. I wish I worked for you before moving out of CA. Another awesome vid.

  25. Avataaar/Circle Created with python_avatars Robert Reite says:

    I'll bet the compressor got single phased. Probably started with sand in the contactor

  26. Avataaar/Circle Created with python_avatars Ken S. says:

    Your Customers obviously Appreciate your Consistent and Strong 💪 Efforts if they are willing to Pay you for two (2) hours of Travel Time in both Directions. 🤔👍🙏

  27. Avataaar/Circle Created with python_avatars atsimas says:

    Pluged filters with very good compressors are more probably to inflict a fault than with older ones just because the system performs closer to the limit.

  28. Avataaar/Circle Created with python_avatars OrangE_AsH says:

    Alright alright

  29. Avataaar/Circle Created with python_avatars joeyf504327 says:

    they should not be doing roof top package units in that environment. Service area Kanata??

  30. Avataaar/Circle Created with python_avatars BS Mechanical HVAC says:

    Wow air blower was helpful

  31. Avataaar/Circle Created with python_avatars Space says:

    Sooooo alright

  32. Avataaar/Circle Created with python_avatars ZE KENZY says:

    Great Video. Thank you for sharing

  33. Avataaar/Circle Created with python_avatars Dennis Olsson says:

    They should have manual (or automatic) switches to shut all units down during a sand storm.

    That being said and people not taking responsibility, they might not care enough to trigger it. And there needs to be ventilation when the building is occupied and so on…

    I'll keep quiet and continue watching. Thanks for sharing!

  34. Avataaar/Circle Created with python_avatars Art Houston says:

    I’ve done mechanical work my whole life, but I did have a part-time job for 19 years as a broadcaster, including being a rock DJ at the foremost rock station in Philadelphia….so I’m going to suggest that this video needed a Music bed of “Enter Sandman.” 😅 Are you in Kanata ?

  35. Avataaar/Circle Created with python_avatars The Project says:

    In the immortal words of matthew mcconaughey, alright alright alllright

  36. Avataaar/Circle Created with python_avatars Piney Prepper says:

    Chris is bad as the sand storms are there I would not allow O/A dampers to open. Not only is that sand destroying their equipment but it's not good indoor air quality . That's just horrible for those filters.

  37. Avataaar/Circle Created with python_avatars Fluxkompressor says:

    A simple ferrule, a 0.1 cent part, could have prevented this (at least the burned contactor)
    I still don't get it, why nobody uses these?
    Other things I don't understand:
    This AC has an 80A breaker (?) going in with 8 gauge wire (?) to a terminal block dividing it into 14 gauge. So in the event of an short or even just overload, the 14 gauge has to pass current to trip the 80A breaker. That would severely overload the 14 gauge wire, just as it did in this case. And the weakest link was the stranded wire screwed in without a ferrule (thinking about that: maybe without that weak point acting like a fuse, the whole wire would have burned up setting stuff on fire)
    Why there aren't any kind of motor protection switches that detects single phasing and over current on an per-compressor basis? Also protecting the small wire from passing 80A
    Such a thing costs like 50 bucks. Against the 500 for a new compressor, that's a no-brainer Service area Orleans??

  38. Avataaar/Circle Created with python_avatars Nick W says:

    When you first had it open and were moving that sand around with your hand I was just thinking of commenting about what we used to call “glamis fever” or sea fever. Anyone who’s ever gone out motorcycle riding in the dunes that hasn’t been there before almost always gets super sick after being in glamis or ocotillo wells, and it’s from the nasty dirt that blows around not just from the salton sea but from all the geothermal activity out there that pumps sulfur, c02 etc out especially like the mud pots, then the wind blows the dirt around and you breathe all that mess in. Glad to see you mask up before blowing the junk off that AC.

  39. Avataaar/Circle Created with python_avatars Glen McGillivray says:

    With the volume of sand in that environment, it'd almost be beneficial to use a vortex sand seperator to isolate the sand from the filters!

    So even sandstorms cannot clog the filters, only the finest of dust.

  40. Avataaar/Circle Created with python_avatars Brandon gotz powers says:

    That contacter is burnt to a crisp damm at least thare wasn’t a fire

  41. Avataaar/Circle Created with python_avatars Jordan Henshaw says:

    Wait you unsweat your compressors? I thought that was a major no-no for fear of igniting oil.

  42. Avataaar/Circle Created with python_avatars Eddy says:

    Be sure to video the compressor autopsy before burial Good vid … Thx

  43. Avataaar/Circle Created with python_avatars 1waffleiron says:

    Aw man, ya had us thinking we were gonna see the compressor cut open 😢

  44. Avataaar/Circle Created with python_avatars dyl444 says:

    if the drier gets clogged wouldn't that mean there are still contaminants in the system? in that case wouldn't you change both the drier and refrigerant?

  45. Avataaar/Circle Created with python_avatars Shaun Kelly says:

    When a breaker trips and you go and reset it and it instantly trips again, don’t keep trying, you have a problem.

  46. Avataaar/Circle Created with python_avatars Shaun Kelly says:

    Looks like they need some sort of sand separator on the intake for that thing.

  47. Avataaar/Circle Created with python_avatars Joe Harry says:

    That is just unreal and the worst part is their is truly no way to control the sand problem 😮

  48. Avataaar/Circle Created with python_avatars TransitBiker says:

    Is there a way to put on some cyclonic dust separator on these, or totally impractical? The separator would have the added benefit of keeping the filters cleaner for way longer, even without the sandstorms. It's insane how loaded those media filters got!

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

    Good job Chris. Service area Nepean??

  50. Avataaar/Circle Created with python_avatars Alex - electrical engineering says:

    Awesome 👍

  51. Avataaar/Circle Created with python_avatars DelticEngine says:

    This was certainly a different video! The main video had a ton of great info in it and the bloopers were a bit of fun as well. It's good to see your lighter side. I have a moustache as well and I get where you're coming from with that with those hairs occasionally irritating like crazy.

    It was a bit of a surprise with the compressor oil with you using metric units for once when you said 'one point six litres' instead of your usual imperial units… I was wondering if you were feeling alright when you said that! You seem to have a thing against metric units.

  52. Avataaar/Circle Created with python_avatars Don Rummerfield says:

    Wow😮 I've never seen that much sand good job as usual Cris

  53. Avataaar/Circle Created with python_avatars Nobody says:

    Those air filters, look like they are filled with fine silt, by looking at the video. (Would see near a dry lake or in this case, possibly Salton Sea shore line / earth.
