It's 120 122 degrees outside right. Now, it's kind of ranging this video is brought to you by sportlin quality, integrity and tradition. We've got our work cut out for us on this one. Today, um we've got a bryant heat pump here.

This is an older r22 unit and we have a refrigerant leak. We had another tech that previously diagnosed it uh the indoor blower assembly, i'm sure you guys can hear that is vibrating pretty bad, so we're gon na pull the top on this, because i believe he said that there was a wire that shorted out against one of The refrigeration lines and uh he thinks it was caused by the indoor blower assembly. So we had actually already quoted this and we're gon na go ahead and pull the unit apart and then repair it um we've got a blower assembly rebuild and then we're gon na go ahead and fix whatever we need to fix on the leak, and hopefully i Have the right, dryers and check valves to be able to redo um the dryer situation, because this doesn't have a buy flow? To my understanding, i believe it has two strainers, so we're gon na get that figured out too. So all right we got the top taken apart um.

I can definitely see where wire shorted out right there. I don't know if that's the leak or not, but i also see oil down below so i'm i'm pretty sure. This is what we thought the leak was, but i need to put some nitrogen in this to make sure the accumulator is not messed up. This whole thing is just vibrating like crazy, there's, no telling.

If this compressor is going to be bad too, it just seems you know sometimes you're blown away that they actually fix this stuff. All right, so that's definitely leak right there, but my concern is: why is there what appears to be oil down at the bottom? Maybe it's not, though: okay well, definitely going to fix that one up and we'll do another nitrogen test. All right. I got this sanded up about as good as i can get it um.

I might get in there a little bit more, but we're going to lay a couple beads all over those spots where it's rubbed out all right. We got in there. We just laid a fat bead all over those spots, nice and thick nice droopy. You can see the nitrogen's still flowing through we're going to give it a good little purge real, quick and then we'll do a pressure test once it cools got to be careful too because notice the smoke coming out, and you don't want it to go into the Return and pull into the building, so you got to watch out for that.

You'll freak out customers, especially if they got people in the building or duck detectors all right. We're going to do a pressure test now pressurize this guy up and then hopefully we hold i'm hoping that the moisture or what looks to be like um dirt stuck to the lines is just because that's the accumulator. So, let's hope - and it's just wet you know so the dirt will stick to it. We're probably going to get this guy up to about 150 psi and then see if it holds how long it holds for my personal experience with doing tightness tests or pressure tests is once you do the initial pressurize you want to.

Let it sit for a couple minutes just to let everything equalize out, especially if there's any refrigerant, potentially still mixed in there, because you'll get some false readings where numbers will continue to change. So i give it. You know three four minutes and then, when it stops moving going up and down, then i hit enter and start the tightness test. So on this one we're at 154.3 we're gon na go ahead and hit enter and then we're gon na this is gon na time.

It for us now, theoretically, you should take the suction line, temperature clamp and put it on there too. I usually don't do that. I usually just look at the pressure all right. This is good enough for me.

I'm not going to stress this too much 0.3 and 9 minutes we're fine. So now the hard part that was the easy part fixing the leak, the hard part is going to be the dryers, and if i'm going to be able to change both of them um this one, i know no problem, but i have to look and see which One is the heating and the cooling think this is gon na, be my cooling one yeah the directions that way. So i know i can get to that one easily. It's the heating dryer, that's gon na be hard to get to.

I would even call it a dryer, it's more or less a strainer all right. I found it easiest just to pull the condenser three braised joints, then i can that's the easy one to get to. This is the hard one to get to so that way i can re-maneuver all this stuff, take care of it and then put it back together. Okay, um we're kind of set up, it isn't going to be perfect and i'm going to have to finagle some stuff and support it with cork tape or something so that way it doesn't rub out.

But for now i have it secured with a zip tie, and i have someone here to help me. People always ask me how i purge with nitrogen on an open line. You have these little step bits. This is made by jb.

You can just shove it in there put your nitrogen regulator on braze, i'm using the vn 500. I think yeah vn500. So it's very slowly purging nitrogen and it's running through and then coming out this guy right here. So we're gon na get this guy sweat in real, quick and then we'll do the other side too boy.

That was not the prettiest i burnt the hell out of that dryer, but it'll be okay um. I can't do that joint until we finish everything up uh. I also found the problem was one of these wires. It actually shorted out somewhere on here.

I can't remember where, but one of these wires rubbed out on there and blew a hole in that line, so i'm going to yank them all the way back and then we'll repair them and put them back when we're all done. So that way, all the wires will be out of my way when i put this condenser back too. This really is a chore, so we got the condenser back in and everything fits, but man stuff is rubbing together. So we're really gon na have to do some work to make sure nothing rubs holes um, i got everything fit in, so i need to braise this joint need to braise this joint and so this joint in this joint and this joint.

So we have three brace joints here: oh yeah, and this one back here. It's a pain but we're getting there all right, not the prettiest braised joints in the world, but we got this one. We got this one. We got this one and we got that one back there everything's on i'm just sweeping the system with nitrogen right now and then we're gon na do a pressure test here in just a few minutes.

It's almost cooled down enough to where i can grab it. That looks like it's holding real good, so yeah we're getting there, and then we got ta figure out all the stuff. So that way like this is rubbing on top of the dryer, we got to figure all that out. That's the fun part, so we're looking good on the pressure test we're at 169.5.

We have zero psi change, it's been running for 18 minutes um, i'm gon na go ahead and let it keep sitting there and i'm gon na go get my vacuum rig. I'm working on doing electrical right now, just trying to secure everything. So that way it doesn't rub out anymore and we're just work. You know we're doing a little bit at a time.

We got the blower assembly in rebuilt. It's got a new wheel, shaft bearings, uh, we're going to get a new belt and then we're going to try to line up this stupid pulley because uh these brackets, they always sag. So you end up having to shim them underneath those guys so we're just working on all that getting there get the vacuum running when we're all done too, i'm going to go ahead and clean this condenser, i just didn't - want to clean it when it was out. It's really not that dirty! I look down inside the inner.

Coil is really not bad at all, so we'll just do it a rinse and we'll rinse the whole inside of the unit out once i get it all braised up, i mean once i get it vacuumed down and all my tools cleaned up. It sucks dragging all this stuff up here, but i brought my water tank up here and my easy up and yes, it takes more time to set up when we got up here this morning. It was only about 90 degrees uh today, i believe the temperature's supposed to hit like 11516, maybe even higher, so it really does pay off to spend the extra time setting this stuff up. So that way you know you're not getting killed and you can drink water.

Like a fish, so i just have one of the yeti cups and go from there. I went ahead and chose to go with spoiling catch-alls as usual. I really like the sportline dryers. I said this on one of my recent videos before i have never personally had it happen, but i've heard horror stories about the little beads breaking apart in other manufacturer's dryers me personally.

I have never seen that, but the horror stories that i've heard have made me not want to have that problem. Um. I've always liked the spoiling catch-all dryers and they seem to do a really good job basic. I keep one of these in my van to show you guys but basic cutaway.

You know it's a solid core desiccant and you know the refrigerant goes through, but i've always liked these they've always done me really well personally, so you know normally, i probably wouldn't have gone with a double dryer set up in the past. I probably would have done just one dryer put it on the cooling side and called it a day, but you know whenever possible, it's best to go ahead and change the heating dryer too uh these carriers don't even cut it's more or less a strainer. That was on there before um. I have one right here: it's a strainer and a check valve this itty-bitty little thing, so i mean it might have some.

No, it doesn't even look like it has any drying capabilities. It just looks like a strainer, so very important, especially since this system was flat potentially pulling in moisture. We've had a lot of humidity out here in the desert, so you know that oil could be contaminated and we want everything in there trying to protect it and clean it as much as possible. We're gon na try to pull a nice good vacuum on it.

Right now, i'm gon na get that all set up and then i'll finish up. The electrical and uh looks like we're at point two pressure differential after 38 minutes. I'm still very satisfied with that. So we're gon na let this roll get the vacuum started, got the vacuum pump running uh got the gas ballast open over.

Here you can see by the red indicator um until we get down to about a thousand fifteen hundred microns and then we're gon na close. The gas ballast by opening it what it does is it saves the the vacuum pump oil. It runs it without pulling it all through the oil. So that way it doesn't potentially contaminate the oil.

So you can do your initial pull down, get most of the air and moisture out of the system and then once you get to about a thousand fifteen hundred ish, i close it and then go from there. So i'm pulling through both sides right now, um! I like to leave these things somewhat, like kind of cracked closed, because there can tend to be a little air pocket in there that gas gets stuck in. So i went ahead and put new connectors. I have these uh compressor connection kits that work good and then we'll uh will secure the lines nice and good and get the cover put back on and do something to make those look half as pretty.

But i cleaned up the connections right here too. What i do as i've shown this before, i think i have a giant mess over here, but i have these uh fitting brushes that i use to clean refrigeration lines. I just cut the ends off and i'll use these put them in the drill and just sand up the electrical fittings that we would get good connections there. So it's a hot one today, it's 110 under the easy up, imagine what it is in the sun.

I was just doing my best to try to secure all the lines, the dryers that way: they're not rubbing out um securing all the wiring. So that way, it's not rubbing out using zip ties, uh yeah! So that's looking good the vacuum's doing good we're at about 795 microns and that's with this side, valved off, so we're pulling just from one side, so we're doing good, we'll do uh, let it run a little bit longer and i'm gon na start cleaning up all My messes on these carrier units these motor brackets always flex and the motor doesn't sit straight, so two washers usually fixes it makes it line up and makes it nice and true. So it sits in there right and it'll. Stop the uneven, wear nice and tight everything's.

Looking good so we're just about done with the evacuation and uh just gon na start cleaning up even more stuff. All right, i purged with refrigerant all the way to the hoses. With these ball valves off made sure i got all the air out of the lines opened these up, let a little bit of pressure in took off the micron gauge zeroed out my scale and uh we're gon na go over here. I believe this thing takes.

Like 10 pounds of gas 11.3 pounds of r22, so uh we're gon na get going on this um. Let's see, let's make sure we're zeroed out on here, yep there's the scale weight right there. Let me hit zero cool open up the high side, open this guy up open this guy up. Let it charge into the system, hopefully, it'll, take the full charge and we won't have to turn it on that would be nice huh bam.

Lucky me: it took the full charge: sweet all right, cool uh, the cool thing about that is that way i can rinse the unit with the top off still so i was going to rinse out all this stuff out of the bottom. Real quick give it a quick rinse on the condenser, like i said i already looked down inside and it's not dirty on the second row, got it all rinsed up we're charged up rinsed, underneath the compressor and all that crap got just right down. Here was a little bit dirty in this corner, but literally all right here i can see straight down here and it's nice and clean all right. We got the top back on now.

I didn't quote this job originally there's a couple things i would have done differently. Had i known this was an aftermarket motor. I would have quoted for a new motor. I don't have one, so this is what it is, but i had to tape everything up.

The other thing is is just by rotating the indoor blower motor. I could hear that the bearings are starting to fail on it. It's probably still fine um, i'd love to uh have money in this. Oh, there might even be enough room here, but i'd really like to get rid of this stuff, i'm going to talk to them, because i want to i kind of want to change that motor and get rid of that fan motor.

So maybe we'll do that and we'll uh get in here and fix this electrical like i've been doing so we don't have all this extra crap right here too, but uh okay, we're gon na connect, this condenser fan motor and get it started up and make sure Everything works. Let's see what happens here. Hopefully, nothing blows up. Indoor blower motor started.

Wait for this to start yeah vibration's much better. It's just a slight slight unit vibration, but nothing scary, convincer fan motors running something's going on here, because my suction pressure is not dropping. Well, it might take a minute, though, let's give it a second, no, but my head pressure's not rising either something's wrong. Here, all right, let's open this up, you got to be smarter than the average bear.

I had these closed still silly idiot. All right now we've got pressure, so suction pressure's a little bit low, but we're going to let it run here and see. What's going on, it's rising. Let's give it a minute i had messed with that reversing valve, so i could have screwed it, but um all right, we're gon na.

Let it run and see what happens here time just timed out and uh we'll let it run for a little bit. Discharging nice good heat out of it right now, so everything's, looking good so far, we'll get some tds on it and stuff too man look at how close that liquid line is it's about a half an inch away that sucks all right. We're gon na turn this on uh we're gon na take some stuff down and i'm gon na go get my probes all right. My unit has been running for a few minutes now, um, let's go ahead and take a look at what we got going on in here, so it's 120 122 degrees outside right.

Now it's kind of ranging um, let's see so we're profiled as a six ton. Super heat's, not bad at all. Sub coins, not bad. It's calling for five, but i'm i'm not going to sweat that sub coins 17 and that's a skewed number, because it's using discharge line pressure instead of liquid line pressure.

So again this thing's looking really good uh. Yes, the outdoor air is kind of changing. It's pretty good. The discharge line.

Temp is like right on the cusp of being too hot, but i mean considering the outdoor air temperature um. Let's see what else we've got going on in here. We have really high return air temperature. This unit uses uh attic temperature as the return it actually uses a common.

They have a very small attic about 12 inches tall and it's a common return for this ac and this ac on their like patio area. This used to be an outdoor patio and it's been covered and enclosed, so we always run high on that um. Let's go in here, so temperature splits a little bit high. I don't doubt that the airflow is a little funky.

It's funny, though, because we're pegged on the pressure scale, uh yeah, we're this thing's. Looking great, we amped out all the motors. I don't like that uh. This is an aftermarket motor, but it's working.

We amped it out. It's running 2.3. It's allowed to run 3.2. We also tested the indoor blower motor.

I believe it's allowed to run 5.8 we're running like three amps right now, so that's doing good too um yeah we're pretty much going to wrap this one up. I'm going to talk to the customer. You know recommend that we consider replacing that indoor blower motor fixing this wiring, maybe change that contactor and swap out that motor, but i doubt they're gon na do it because the ac is working right now and i don't blame them. So these things run hard.

I i realistically think we'll get another year, maybe two out of this unit and then it'll be time to change it um, but you know that's their decision to make not mine all right. That was a hot day: okay, um it started out in the 90s. I think at one point in the video i think i showed like 110 or something like that and then uh as we were leaving it was 120. 121.

I think, was the highest that measure quick set and that was not really like in direct sunlight. That was more or less um and just partial sunlight in the shade uh. The hard part was getting all that stuff that we had on the roof across the roof. Okay, it's really difficult to keep your wits about you when you get into a day like that, that's why you really need to mentally prepare ahead of time, or at least that's how i do it.

So i knew the night before what was going on. I went ahead the night before and did as much driving around as i could wrangling up the parts finding the check valves, the dryers when you do jobs like that. So i didn't diagnose that unit okay um someone else did and i had a few vague pictures, but i was like trying to go back the day before and think like okay, what kind of dryer does that unit have trying to remember in the back of my Head what they did, because i didn't know if i needed to get a buy flow, i knew it was a heat pump. So you know, and then i found one picture, one tiny picture that showed just a glimpse of the strainer and the check valve and that's when i knew okay, i need to get you know new check valves and i because i wanted to go in with spoiling Catch-Alls, i i knew that i needed to get a different check valve, because i was going to need to move things around the little dryer that they use is like tiny.

I shouldn't even call it a dryer, it's just a strainer, so it's real important to understand the way that those systems work. Okay, understand the reason why we have those check valves essentially, so that way the refrigerant doesn't flow, the wrong direction. You know and contaminate. You know mix liquid refrigerant with vapor refrigerant.

It would just be a nightmare okay, so um just trying to plan ahead, really helps me out uh the night before i packed up the van, i had everything loaded. I knew i needed to leave super early because we were having the restaurant get there early because of the heat. So we had them arrive early. We arrived early, we already had everything packed up.

I had the water jug packed up. The only thing i didn't have was i had forgotten the belt. That's all so we had to send. I had another person with me, so i sent him to the supply house to get the belt and other than that we had everything else on the roof that we needed to um.

I just like to sell to be super prepared for those things and try to plan for the worst case scenario. So in that situation i was on a remote roof. You know on the other side of the building that was away from everything else, so we brought as much stuff over as we could. We put up the easy up right, quick.

We brought a water hose over. You know we had everything ready so that way it just made everything go smoother. Okay. We took lots of breaks too really important when you're working in that kind of heat, because it's really easy, at least for me, to get super into the zone and not pay attention to myself.

Okay in the past, i would have done that job without an easy up, and i would have been over there dying. You know, and it's like man, what a difference. The easy up does just to keep the sun off of you just for a little bit. You know and to keep the main area working cool cooler.

I should say um. I uh. I didn't do it this time, but i've gone as far as wearing like head scarfs that i soak in water. I really didn't have to do that.

Okay, when i, when i work in the heat like this, i wear long sleeve shirts, i wear an undershirt that wicks the sweat away, but the long sleeve shirt keeps the sun off my arms. I really like that. It's just the dickies work shirts um. They they work really well for me, um all right.

So in the video you know, i kind of mentioned that there's a few things that i would have done differently. Had i quoted it now i realize okay, maybe some of you guys may have thought. Why didn't you just do it? You know um, because this was a quoted job with a particular customer in this particular customer. I didn't want to change anything plus.

It was already hot enough. I didn't want to try to redo anything else. I wanted to spend the least amount of time on that roof as possible. Now there is some other issues, such as the electrical uh that main wiring.

That i said i wanted to fix. As i was reviewing the footage, i realized that there wasn't a uh, a bushing protecting the wire or chase nipple. Protecting the wire was just running through an open hole. I definitely want to fix that stuff.

But again i wasn't trying to reinvent the wheel. Basically, okay, i just wanted to get the unit operational, get everything working so that way i could get out of there now um. I arrived on site around 6 a.m and i left around 2 45 p.m. So we were there for a good eight hours, um and uh.

It took me about an hour and a half to get out to the location so um i left my. I think i arrived on site at 6 30 because yeah i left my house at 5am. It took me an hour and a half to get out there, so it was a long day to say the least. Okay um and there's very good possibility.

Uh we're gon na be going back there soon, because there were some other issues that i had found. They had another ac that wasn't working and um yeah, so we'll probably have some more video footage of that too. But i try to be as prepared as possible and try to take as many breaks as possible. We were drinking water like a fish.

I think between the two of us, i think, when we were all done, i think we drank two gallons or three two or three gallons of water between the two of us, and there was many times not many times, but there was one or two times where We both went downstairs, um cooled off in the building and then actually walked into the walk-in cooler. Now that's another thing: i want to address too being very careful not to shock your body. So what i do, what we did the first time um well, when we did it together was we both were starting to remove stuff from the roof uh, and we both kind of acclimated in the building for about 10 minutes. Okay, just the normal condition: space about 77 degrees, 76 degrees acclimated in there for about 10 minutes, and then we both walked into the walk-in cooler, but we had long-sleeve shirts on so our bodies weren't shocked with the cold, but it just really helped us to cool Off you got to be very careful about coming from the really hot roof and then immediately walking into a walk-in cooler, a walk-in freezer, because you'll shot you'll go into shock and you don't want to do that.

That'll create more problems than you need. It'll make you get sick and all kinds of things. Okay, so you want to try to acclimate slowly and don't don't go from one extreme to the other, really quick, because it won't be good um, but yeah just make sure you guys take lots of breaks um when it comes time to being prepared. Okay on these jobs too, you know, obviously that really is dangerous, working in 120 degrees, okay, because usually by the time, you feel the symptoms, it's too late.

Okay, if you start to feel you know nauseous when you're working on a roof like that, it's too late. Okay, you need to keep on top of that stuff. There's been many times in the past, especially when i was younger that i didn't pay attention to my body and i was like i'll be fine. I'm almost done i'll just work through it.

You know, and it there's nothing worse now: i've never personally had a heat stroke, that's not something that you want to go through. I imagine because it's not good for your body, but i've had heat exhaustion many times, and it's not good. So you know, as i get older, you obviously hopefully get wiser and i'm very conscious of everything. That's going on drinking water like crazy, taking breaks staying out of the sun as much as possible.

Try not to exert yourself trying to be smart too. So, every time we had to go down to the truck to go, get something we took something down with us. Okay, we try to, you, know, be as efficient as possible and we tag teamed. You know taking all the stuff off the roof we did it together is for the most part we did the big bulk of it.

You know, but yeah just being prepared, that's the biggest thing, having as many of the things that you need up on the roof. With you that way, you don't have to make multiple trips back and forth the least amount of trips, the better walking across the roof. It gets really hot uh. We were lucky today in that uh it.

Actually. It was today well duh, um. The the this video is being released the day after i did that job, so we were really lucky that there was no humidity because they have been having uh. You know monsoonal moisture coming through there and it's been kind of humid.

Today it was rather dry. I'd say it was 20 25 humidity, so it's super dry and that made it a little bit more comfortable okay. So it was just that dry heat. It's still, i mean 120 degrees, still is ridiculous.

Okay! Now one thing i did do today that i probably shouldn't have done was i worked through my lunch um. I probably shouldn't have done that because you know food actually, so i don't eat breakfast. So you know i hadn't eaten anything since the night before and i worked until two o'clock and then i ate my lunch at two o'clock, probably not the smartest thing. You know um i'm trying to get better at that stuff, but still i get in that zone where it's like man, i need to power through this.

You know i'm almost there and probably not the smartest thing in the world to do so. Do as i say, not as i do kind of a thing um but yeah. If you know energy and stuff like that, comes from the food that you eat and everything too so taking care of your body really does help you on these jobs and there's always room for improvement. For me too, so hey i've been rambling long enough.

I really really appreciate you guys taking the time to watch these videos hey. You know what now that i think about it. I totally forgot to mention it. You guys are killing it on the the hat orders and the shirt orders.

Man. Thank you guys. So very much you know uh my gosh. I i'm, i think, i'm down to like 30 hats or something left and i've already got another order on order.

So, thank you guys so very much, and i think i mentioned this on my last video or on my live stream or something but um, i'm working on beanies too for the um the winter time. Those will be coming soon. So i'm working on some different designs and i just ordered up some samples so hopefully we'll have those soon so that'll be kind of cool. But again, if you guys are interested, the merch is available on hvacres.com.

I totally forgot: we got the overtime show this friday uh around 6 15 p.m. On the hvac overtime channel myself, a team adam or adam muffetch, joe hvacr, north and uh uh curious hvac guy bill.

Sorry, your name skipped my mind you're, so forgettable bill. So your name just totally skipped my mind for a minute, but anyways now bill's a good dude, so uh we'll be on there just discussing random. We do the cool, hangout kind of a show on friday evenings so come check that out too okay, we will catch. You guys on the next one.
