Look at these man. These things are just pulled in completely it's june. 22Nd. 2020.

So these haven't been changed since january. That's crazy and these ones are actually sucking in all right. I want to start this video off and just say that we have large extra large hats in stock. Again, a lot of people been waiting just a little information about the hats.

These hats are black flex fit. They have a black under brim. They do not have my logo on them. Purposely they just say hvacr, just kind of has my color scheme on it.

Okay, i did that because i wanted you guys to be able to wear these hats to work and not necessarily represent my brand. While you were at your own work, i have my own company and i don't want my guys wearing someone else's brand. You know i don't want someone to think this. Is another service company or something like that.

Okay, so i purposely did that. So that way, you guys can wear them and just you know, they're informational, they say hvacr again, they're like a breathable flex, fit material. You can actually see through them. I can't really show you this, but i can see the light through these things.

They work really good, they last quite a while so again, they're available on the website. Right now, the the large extra larges there's a lot of them. I think there's 99 available uh the small mediums there's just a couple of them um but yeah. That's it we're gon na get on with the video.

Now this video is brought to you by sportlin quality, integrity and tradition. This is a saturday morning call they called me last night saying they had water leaks coming from multiple acs. I can already tell you: what's going on, i've done a lot of cleaning already at these restaurants, so we're gon na have dirty filters, broken belts. They said the bar was the biggest issue, i'll have to figure out which one is actually the problem, but i just have a feeling: we're gon na have to be cleaning pretty much every ac up here, so no obvious signs yet so we're gon na open up The returns and see what it looks like inside definitely some airflow issues.

Considering the filters haven't been changed since january 22nd. That's gon na be nice and then we'll have to open them up and see. I can hear belts loose on this. One drain is clear on this one: this is their bigger bar, but the coil is hammered.

It may not look horrendous, but it is jammed in there. The stuff - and this is always like you - get this big - build up where the filter creases are where the filters meet. You know right here. You usually get big buildups, but let's go look at the other bar i see and see if the drains plugged up on that one all right.

This is the smaller one, and this is interesting because the drain is not plugged up on this one either. So it makes me wonder where this water leak, they said it was leaking on the customers, interesting and interesting. This is another one of their ac's, that's nowhere near the bar, but these ones look at these man. These things are just pulled in completely it's june.

22Nd. 2020, so these haven't been changed since january. That's crazy and these ones are actually sucking in because they're plugged imagine we're having some airflow issues on this one. Look at this one.

This one is uh full of water. The drain is plugged down there. I don't know if this is the one they were talking about, but damn they said the bar. This is nowhere near their bar.

These p-traps all need to be redone. Let's power it down. As far as the bar acs go, i'm going to start on those two, because those were the main ones that were supposedly leaking, but i don't have plugged up drains on either two of the bar. You sees this one or that one the filters were dirty um.

So we're gon na start just by checking the units out, and maybe it's not something as simple as a plugged up drain. Maybe the coil is icing up. Maybe we have a restriction in the metering device causing you know, weird frost patterns who knows i've also seen where the the first stage compressor is not working, and the second stage is the second stage is above the first stage, so the water drips when it condensates And then gets pulled off the coil there's all kinds of weird things: um, so we're gon na start with the belts and then work our way there. Surprisingly, this belt's not that bad.

They must have had these units shut down during cobit and not running normal schedules, because i mean there's light wear, but this is the last pm. I don't know if we changed the belts on the last pm or not, but i would assume we did, but yeah those don't look bad at all nice and snug too huh interesting. The smaller bari sees belt is looking good too. I mean slight wear to it, but not enough to change it, nice and snug, and we got a spare, so they must have had these units shut off if they did what they were supposed to do.

I think there was a corporate mandate that they shut off their acs during the whole thing, because yeah these things are looking good, um huh interesting. So i still don't know where this water's coming from i'm gon na, have to open up the ducks and look and see if i can see traces of water in them. This is the one the smaller bar. If we get down in here and you look back into there - that's all water right here, it's all wet and then you can look over here, and this is all wet right here, too yeah.

So the water was coming from here, but the drains not plugged up what could be. We need to look and see if that trap is dry. If the trap is dry, that could be it so we're going to open that trap up. I can't stand all that stupid tape, but yeah, let's open that trap up and see if it's dry, judging by just taking the tape off and the water dripping out of it, i don't think the trap is dry.

Oh yeah, that's dry! That's a dry trap for sure, but no that doesn't make sense, though it still shouldn't be dry like that, but the fact that there's no water in the drain pan right now when the unit powers down and the fan turns off, it would have filled the trap Up, so that's definitely not good that the trap is dry, but there's something else going on here. I put a little bit of water in the drain pan and it's just sitting there and it's not draining so we just have a slow drain. I think that the the dry trap was uh simply because it has a coupling right there and the water just drains out overnight out of the trap um. So this is plugged up right here, so we're going to open it up and blow it out.

It's kind of hard to show you with the camera, but the evaporator is not too bad um, but it is dirty. So i'm going to go ahead and clean it with some evap cleaner, i'm going to use the viper venom pack evaporator cleaner! I got over here and it's hard to get without making you guys go upside down and inside out and uh. The drain pan is clear too, even on this side. Normally i've shown it in some videos where it's really dirty on the backside.

This one's rather clean, which must mean that i've cleaned this one somewhat recently, because even those blower assemblies, this blower wheel's really clean too. So i must have done some work on this a while back. I know i put a heat exchanger in it about a year or two ago. Maybe i did it, then i don't know anyways, but i'm gon na go ahead and clean it with some evap cleaner.

It's not super soiled, so it shouldn't take much um. I mentioned in one of my videos recently and i got some feedback about the viper coil gun. Someone had said all the coil guns are the same. It's the same as every other manufacturer mechanically.

It is the same okay. Mechanically. This gun is the same. As you see with other people, but the concentration or the dilution ratios are different.

Okay, so basically the little chingus up in here that pulls cleaner, while the water's flowing through is different. So the viper coil gun uses a lot less cleaner, so you're not going to waste as much cleaner. So there is a difference, especially if you're using the viper cleaners. Okay, if you use their cleaners, trust me, you want to use this because you'll get the full benefit of this venom pack using the multiple nine gallons.

I probably get six to eight gallons because i mix it a little bit rich. But if you use the other manufacturer's coil gun where you fill it up all the way and you can use it within two minutes - you're going to see that i'm going to pour the smallest amount of cleaner in here. And it's actually going to be too much. And we're going to use very little of it.

That's about the minimum, just because i want to make sure that this goes all the way down, but we probably won't even use all that. It's it's amazing and the other thing too. I've said this a couple times and i just don't want people to get confused, because i was a little confused when i first started using this is the the lettering is different, so, on the other manufacturer's gun a is the most on this one, a is the Least e is the most cleaner used, so we're gon na foam this guy up real, quick, i'm running on the c setting, okay and you're gon na see it foams rather well. So you actually have to be careful because it'll foam up so much that it'll overflow, the drain pan.

So you got ta, be cautious about that. So make sure you have already saturated your coil, which i already did and we're gon na spray some cleaner down in here, we'll just let it drain down in yeah. I got to be careful, i'm getting it down into the ducts, but i'm going to put the camera down, so i can do this without getting it in the ducts and then we'll spray from the other side too. The key to their cleaners is, you have to let them sit longer than you would with the other manufacturer's cleaners.

Okay, you got to let them sit and you got to let them break up all that stuff. Again, you see all that foam. That's what i'm talking about it'll start to overflow, which it is a little bit so got to be careful because you know they don't have customers in the building right now. So, but still you want to be very cautious, but you notice how much foam is in there and how much water is coming out because most of it's foam right now, so just let it sit and do its job and then rinse it technically.

This is a no rinse cleaner, but i like to rinse it just to see the dirt come off and everything when i say no rinse cleaner, because it has condensation uh dripping off the evaporator itself rinsing, but i also used it a little strong to get the Real good foaming action going on, so i am rinsing it starting from the bottom working my way up just a little bit at a time. It's not coming out bad at all. So that's good! The last thing i'm going to do when i'm doing the cleaning process is i'm going to use some sanitizer and i've shown this before, but i've never shown the process of doing it. It's super easy um.

This is their strike back cleaner and i pre-filled this quart bottle with water and just do two full pumps. That's all you got to do two full pumps. It's got plenty of sanitizer in it and then we're just gon na spray. It down on the unit and you're not going to rinse the sanitizer, just like on an ice machine.

This right here is just going to sanitize all the surfaces that we've touched um and they tell me that it's completely safe, i haven't had any problems with it. I've used it many times, not gon na hurt a single thing. All i'm gon na do is just spray, this stuff, all over the evaporator and all over the surfaces where my hands were touching and just let itself dry self rinse. Whatever it's not gon na hurt anything i mean obviously don't spray it in electrical.

Obviously, that's dirty. I'm not gon na go crazy with this, but i'll spray it in here too, on this side, um put it on the stream setting and get it back in there. You know it's just like a cool thing to add to the invoice that when you were done, you sanitized everything. That's all you know, and i mean it's peace of mind too.

If you think about it, then you know you know: you've done all your part with the whole virus and all this stuff to try to prevent anything. Now we're not saying this stuff eliminates the virus or anything like that, but um we're just doing this just to be safe, not making any crazy claims or anything like that. It didn't take much at all. I just split the condenser.

Really quick didn't even have to pull the fan motor um - it's not horrendous, but it is dirty in there. So we're gon na give it a quick little rinse, um and then spray some cleaner on that and then we'll gauge up and check out the unit. Again. I'm not just stopping and saying it was a plugged up drain, i'm making sure because it could be a slow drain and it could be a restriction in the metering device.

Who knows there's so many different things that could be going on here. So big picture. As usual, gon na give it a pre-rinse just get some of this stuff out we're not going crazy right now, just getting the condenser wet, getting some of the big chunks off we'll rinse from the other side too. Some of that stuff off get on the inside same thing and then we'll clean and of course we want to clean from the inside out.

Do it correctly, you know, but we're just going to get the whole thing. Nice and wet and uh we'll come over here to this side, which i already opened. This one up looks like someone. I think i've talked about this unit before this someone's done a lot of creative stuff, with pressure controls and put aftermarket ones and whatever condenser is not too bad.

We're just going to give it a quick rinse. I can actually see through it in some spots, so we'll still put some cleaner on there just to make sure we get any built-up grime out of there same thing, we're going to use the strike back, condensed, coil, cleaner. It only takes a little bit doesn't take much essentially the cleaner i have to put in. There is just enough for the chingas to reach the bottom of the cleaner, and that's it.

We won't even use it i'll end up pouring it back into the container. When i'm done, but that'll do multiple acs that little bit this is highly concentrated stuff. So remember this bag is going to last. You multiple multiple cleanings, i would say the way i've been using it just like the evaporator, cleaner i'll, probably get about six cleanings out of six gallons out of this, so cleanings it's gon na last a long time, but if you're doing like i'm not doing all The acs today, because i just need to get the bars done, but if i was doing all of them that bag would be more than enough more tha.

I'd probably only use if even half that bag to clean all these ac's bring it on there. On the b setting, he isn't boy, just let it sit you got to let this stuff sit for five to ten minutes. It's not like. I again, i know i keep preaching this guys, but i swear this stuff is awesome um, it's not like the other brands that, if you let it sit, it'll eat the condenser away.

That's not the case with this one. So the key to this stuff is to let it sit and remember that this stuff is all safe. So you know it may take a couple different cleanings. You may do need to do two cleanings, but it's not corrosive.

It's not eating the roof away like it's. Just soaked guys get from the other side too, and just let it sit and do its magic. Okay, how much cleaner is still left in there barely used any. So that's more than enough cleaner, we're just gon na.

Let it sit and then we'll rinse it. So we're all clean. I didn't pay attention, it's frustrating and uh. When i was hosing everything off.

I didn't realize that someone has the capacitor dangling right there, because i was soaking all of that back there frustrating. I don't like aftermarket crap, gur all right. Well, i'm just gon na let it drip dry and hopefully it doesn't short out when i turn it on i'm gon na start assembling it because i still got another 20 minutes putting the unit back together. So, let's hope that nothing shorts out looks like it started up.

I don't know why that happened had a call for cooling or something, but the indoor blower motor is running. We might have to jump it out all right. Our unit is up and running and measure quick, yeah we're running with a wet coil, so we got to let this guy calm down, but look at that suction pressure, how low it's dropping the saturation temperature's going down to 16 degrees. We doggy that's really low.

That's almost low pressure cut out time. We are running with a wet evap and a wet condenser, though so, let's give it a few minutes to see if it stabilizes out it's slowly starting to come up. So it's probably just that initial startup we're going to give it some time again to dry out the coils and let it operate. Outdoor air is 82 return.

Air supply air, okay, cool we're going to let it run while i'm waiting for that unit to stabilize out and dry off the coils. I'm rinsing all the other units, i'm not doing a full pm, i'm not splitting the other units right now, because i don't see the need to well. No, i take that back. I do see the need to these condensers all need to be split, but i'm on overtime right now, so i don't want to be here any longer than i have to so i got that unit running like it should well we're going to verify the pressures right Now but while i'm waiting for it to dry off instead of just standing around i'm doing something, so i'm just rinsing condensers real, quick clearing drains real, quick, nothing crazy, i'm still gon na recommend full pm, but we're just you know, keeping busy, basically not wasting their Time or their money okay, so we got multiple things going on here: first off um, according to measure quick, our head pressure is a little bit high.

Okay, our super heat's a little bit on the low side, sub cooling's yeah. It's all right, ish um! It's a little bit on the high side, but our airflow is an interesting one. We've got a good temperature split, our temp splits about 21 degrees. Let's see what we're supposed to have.

Also it's actually saying we should have about 17 degrees uh. It looks like we're low on the airflow. We're a six ton, so technically should have 2400 cfms um. Total external static is right on the money.

This unit has a maximum static pressure of one inch um and if we click on that, does it tell us the no? It doesn't tell us what we're actually reading we have to go into the tool manager if we go into the tool manager return. Air static pressure is at 0.62 supply. Air is at 0.36, it's always possible. I think we got multiple things leading to an issue here.

Let's see what measure quick has to say about it, i'm thinking some airflow issues and maybe an overcharge. So it says dirty, condenser non-condensables. We know it's not a dirty condenser 100. I don't think it's non-condensables airflow is low and then system may be overcharged with refrigerant.

Slightly because the superheat is moving, so that's why it just went away and then came back. It's not horrendous, though the unit's in decent shape, there's not a whole lot. I'm gon na do today sometimes on these units on these carrier units. They'll uh they'll have plugged up metering device, restricted metering devices.

You can usually see it, though, and i don't see any frost pattern on the the little accurate or metering devices, but that sub coin's a hair on the high side. For my comfort um, which makes me wonder if someone added gas to this, i know i've worked on this unit before i can't remember what i the conclusion i came to last time. I worked on it. I've got so many videos, it's hard to go back and review it all.

Well. The first thing i'm going to do is i'm going to check out the motor pulley and see if we have any room to speed it up. Looking at the static pressure, i mean we could have a dirty return: air filter, a return air grill. We're currently running no filters right now, so we could have a dirty return: air grill, it's very difficult, very high in the air to get to theirs.

Let me look at the pulley and see where we're at with the motor see if we can speed it up at all, but that's going to increase our static pressure and we're already almost at the limit it makes me wonder. I can actually probably prove a dirty air filled or dirty return. Air grill by opening up the economizer damper. The economizer is not hooked up on this guy.

So if i manually open it and our temp split drops, our air flow goes up and our static pressure goes down. We might prove that we have a plugged up return. So that's what we're going to do we're going to try to adjust that motor pulley, real, quick, okay, the economizer motor has been disconnected. You can see, people got wires, cut all kinds of crap.

So what i did was loosen up the screws and then i can open and close the dampers and then i can tighten the screws down. So we're gon na go something like that. We're gon na pull a bunch of outside air and see if that helps our td and helps our air flow, and if it does, it's going to prove the whole dirty return. Interesting, though, with the dirty return, you would expect to have a lower than normal suction pressure.

That's an interesting one. I don't know okay. Well, let's see what this does. This thing is a mess.

It's working it's working about as good as it can there's a couple things i'd like to do. I don't know if they're gon na prove it, though um i got our super superheat up a little bit. I ended up removing some refrigerant from the system. Just a little bit, my airflow, though, is not improving.

Um sub coins still a little bit higher, but we're looking at super heat on this one um my discharge temperature. Our saturation temperature is a little too high for my liking. Right now, my temperature split is okay. It's about 21 degrees, it's a little bit on the high side, uh airflow i mean i got it up a little bit, but not much um static pressure isn't really changing too much by opening up the outside air damper.

It's kind of went up a little bit to be honest with you, so what i'd like to do is a couple things. I've i've run into this problem here before i'm going to do some research uh we're probably going to leave this one alone, but i'm going to do some research. I want to know if the right is in this unit because it has been replaced and the previous company i've seen them put bigger compressors in these things, and that just throws everything off. The next thing is.

I want to make sure that it's the right condenser fan motor. I want to make sure that we're not supposed to have like an 800 cfm condenser fan motor um, although no that would raise my head pressure up even higher, so no that i don't think connects family is the problem uh. The next thing i would like to do is talk to the customer about coming in here, and let me go ahead and recover the charge out of this unit. Change the dryer, pull a vacuum and start from scratch.

Put fresh r22 in there weigh it in because i don't know what's been done to this there's different pressure controls. There's an aftermarket fan motor, an aftermarket compressor. I don't know what the deal is it doesn't. It might have a slight restriction in the metering device, but i don't know man it's right there, but anyways they are operating.

The water leak is solved. The unit is doing as good as it can be. I did get the super heat up, so we're not flooding back to the compressor as bad anymore, so we're going to tell them to keep an eye on it and we'll make a few suggestions. I just don't like that.

Discharge pressure - that's a little high for my liking, but yeah. We know the condenser is clean. We know there's nothing wrong with that. So that's it.

I don't know if they're going to continue with anything else on this unit. I definitely know that we're going to have to come back and put air filters in every one of these units, because i pulled all the air filters out for now, so we'll see what they want to do all right. So the repairs they're not always perfect right in this situation, this video was shot a while back. I've had this one sitting in my archive and i just hadn't edited it yet um.

This was shot back in june. Clearly this was coming out of the first lockdown in southern california: okay uh, the restaurants were just kind. We were still in lockdown, but they were starting to get ready to be opened back up again and then obviously it shut back down again because now we're in august and they're still shut down, but anyways uh. We weren't getting a lot of air conditioning calls, but situations like this, the customer would call me out for a water leak and then i'd find everything was smashed.

You guys saw how dirty the filters were. They hadn't been changed since january plugged up drains plugged up condensers dirty evaporators, we're still cleaning up the messes from that first lockdown and we're in august right now. Okay, now, when it comes to the repair being made um, you know we can't always get the big picture repair approved in this situation. The customer chose not to go with the repair um.

They were happy with the unit. It's working as good as it could right. You know without making any major changes and they still aren't seating people in the bar area. So they really don't want to spend the money to upgrade that unit.

Now i did inform them hey. You know this is going to cause compressor failure, you're going to have issues, and they realize that, but because it's operating they just want to leave it be, and i'm not mad at them for that. Okay, just because i give them a big picture. Diagnosis does not necessarily mean they're always going to go for the big picture repair in this situation.

What i quoted to them was to go ahead and let me recover the charge and i went ahead and told them hey more than likely. This unit is going to have a plugged up metering device. It's a fixed, orifice restrictor. It has like seven or eight different uh inlets into the evaporator coil.

I kind of said you know more than likely it's going to be that this is going to be the cost to repair it, and then i wanted to put in the oem condenser fan motor and then i also wanted to get up and clean the return. Grill. Actually inspect the return grill, and then i told them, potentially we needed to clean it too, and they just kind of said. You know what not right now, because they don't have the money okay, and it is what it is guys.

We got to just be thankful for the work that at least i am i'm thankful for the little bit of work that i'm getting from these restaurants, as it is okay and i'm thankful cross my fingers that they continue to pay their bills. Okay, now uh about the the viper cleaner, so i was using the viper condenser coil, cleaner, the venom pack. I was also using the viper evaporator coil, cleaner, the venom pack, and then i also showed the strike back. Sanitizer i've been really using that strike back sanitizer.

A lot and just kind of for my customers, peace of mind and, in all honesty, i'm not even charging my customer for the sanitizer. It's just kind of a courtesy thing that i do as i'm leaving the unit couple squirts in the area that i was working. Just to make sure that we have all the areas that we were working on clean and sanitized, i'm not making any false claims, even though that sanitizer does kill certain things. Okay, i'm not even claiming that to the customer, because i don't even want to tread on that.

I don't want to start going down that path, i'm not making any claims to the customer. All i'm telling them is that i sanitized all the surfaces that i had access to, that. I was working on to make sure that i'm potentially not bringing in any extra bacteria viruses or anything to the best of my ability. Okay, but i again, i am not making any false claims trying to say that this kills everything.

Okay, even though i do know that it does kill some stuff, i'm just not even going down that path. Okay, um anyways. As far as the refrigeration technologies products, you guys can get those at your local supply house. I highly suggest you guys ask local see if they have it now.

In my case, a lot of the supply houses do not carry it local, okay and a lot of the times. I end up having to get it from true tech tools. Now some of my supply houses carry some of it and i can have it ordered in, but when, if you guys can't yourselves, then i highly suggest you guys check out truetechtools.com they're an online website great people over there. They have great customer service lots of great products.

I actually buy a lot of tools from them if you guys check them out and you, like their pricing, do me a favor and use my offer code. Big picture. One word big picture: okay, you'll save eight percent. On your order - and i get a small commission from that - helps to support the channel.

Okay um. I really really appreciate you guys watching this video leave me some feedback. Let me know what you think was going on in the system. Do you think my diagnosis of a potential restriction was correct? I'm always looking for feedback.

I'm you know. Sometimes you guys give me ideas and it's like hey. I never thought about that. Okay, so i'm i really do love to read those comments.

So do me a favor leave me some comments. Send me an email, um, remember, monday, evenings 5 p.m. Pacific time on youtube. I go live and i usually talk about these videos answer the comments answer the emails, so let's uh or hopefully you guys - can make it and check that out.

Okay, i really really appreciate you guys and we will catch you on the next one.
