 All right, so we're here for a no cooling call and this is just a residential split 5 ton unit and It's for this commercial application here store And he said it's warm in there so outside temperature out here. We're somewhere around 80 degrees Yeah, about 80 degrees outside And I know these coils are clean because I cleaned them just a couple months ago We're gonna go inside and take a look around. I already have a feeling. I know what's going on here so far That you know, it must not be doing too bad So this is the air conditioner here So they got going on at 54 degree air I think that about the same as our suction This is a 12 to 1 ratio on the infrared I believe we have another filter back here in the back And there's some in the ceilings 83 degrees 79 to 83 81 just depends on where you're at So go to the air here. It's 65 degree air 55 degree air there, 56, 49, somewhere above work So the filters are pretty dirty So let's let's get those yanked out and see if we can start getting some better volume coming out I think what we got is just plain simple not enough air flow Like I said, when you check in here, it's 80 degrees Which is exactly a large electrical T87 electronic thermostat says Yeah, I even swept these grills off because they were kind of dirty Problem with this deal here Is they didn't put a box above it so these filters get dirty a lot quicker than what they need to They really need is about a four inch piece of sheet metal up there on top to raise it up higher so that you don't have Simple circle patterns, so you're losing all that area there in your filler That's a common mistake that you'll run into You can see That's kind of pulling it unequal areas Just worked on that beast not too long ago. I think it was a pain in the butt So we've got that out of there. Let's see what we get for air flow Check the filter in this furnace, which I don't generally like having that many filters Because you're reducing air flow This place has got a lot of dust So there's our trunk line going back to the furnace. It's stuck board Quack-quack, but I think that bad up here spot 83 up here. So we're only about three degrees former the lights are LED so we don't have near the heat out of those that we've had before But we definitely got air flow issues All right, so we took the grill off of this. I've got better air flow now I opened up the butterfly dampers. They're a little bit We have problems lining that up with the duck. The duck comes this direction and the butterflies are this way It tends to stop the flow a lot worse Let's check some of the other ones out here. We've got windows So there's a lot more infiltration I'm gonna try to get this one opened up a little bit more. I'm not real thrilled with the way that is So we'll open that There we go. It's a little bit better So the air is coming from this side here and it hits that damper it slows it down big time So we've got pizza ovens right down there When you come up here on top we've got two Runs you can see that silver flecks over there and this silver here. There's not cold air coming out of that It's definitely not cool. I mean, it's fairly tempered So I'm gonna see where that's coming from whatever that is isn't Helping with our heat load because it's definitely bringing the load in It's out here and it's above the ceiling Which we've got to go out here and see You can see it little burger hidden back here It's not running Well, that's what those other ones were that we're just blowing Air that was being sucked off the ceiling so Can't tell yet. So this thing opened up. That's definitely Not helping us none, but it's a two-ton unit See what It's like our contact is pulled in Just need to see if we got a voltage there There we go all right, so Got some helpers here But we ended up running into As we have thermal overload on the compressor faster checked out fine Fan wasn't running because there's a fan cycle switch on it. So we jumped it check the pressure We do have the fridge run in there So I don't know if the switch is bad or the motor's going out that caused it or is the compressor just jump So we're gonna pull this thing down and see if we can get it going All right, so we've got the compressor on there Invention go ahead That's a pretty good job usually So now we're starting to cool her down to what we could do Since this fan cycle control is not going to turn on the fan. We can actually plug it in That way when it actually meets Close contacts and being on the overload The compressor pick on I don't know I'm done run the water Have to run the water any longer than I need to Make sure that I put a good stand right here with it. Otherwise this fan will also problem Check these wires here see through okay Too much after Then everybody know he's got beer before he drives home, right? Yeah No, not at all right, so we're still trying to cool down that compressor go ahead and hook the meter across the Common and run windings on hook the fan Unhook the contact and kill power So when my meter beeps, I know I've got it Right now kind of out there just waiting Probably could check that filter there to see how bad it is. It's probably not very dirty What we really need to do is get a Five-inch filter stick it right here and just let it do all the work Instead of a little dinky one-inch filters because that's just too long in between services for to survive Completely blocking the light, but it surely isn't helping it Definitely needs a new filter All right finally got it So let's see what happens here Right, so we brushed this off for now. We'll have to come back with some other filters and Honestly, I just kind of Switched to a thicker one, but it's not like this just happened. It's been going on for years so Now we gotta find the air handler for the other one and check the coil probably works leaking as what I'm assuming So we can do this one of two different ways we can either Oil everything up get it ready to go And get it on there and you lose a little bit Or you can pump it down, which I'm feeling like pumping it down. I don't usually do it like this But today's a special occasion. I guess I just feel like it So I go ahead pump this thing down take it back on This back on Because if you stand hook the one there, there's no straighter in that port for the fan Comps like control we're gonna get blasted in the face with refrigerator, which was very pleasant It should stabilize right now looks like about it is Also kind of test out our compressor valves at the same time It's not for me Positive here another benefit of doing it like this is if you by chance have a stick to straighter core or somebody decided to play Yankee Doodle dandy with you and Remove the straighter core. You'll have a root awakening. So it's a little safer to do it this way so Didn't take one extra minute just a little more reassurance kind of learn from your stakes I haven't had it happen too much, but it can and does happen Got our swivel tea in there. We ended up just oiling it with some POE oil Got it on the back of the flares, which is kind of nice over the Nylon I love it's kind of paying the butt to get it to the very back side of that flare joint Especially with that short little section there You've got the oil just penetrates right into it got a little piece sleeved here Got a nice little wire tie there. Everything should be tight and tidy You have the control this time sideways. So it's a little easier to adjust Obviously once you adjust it won't be missing with it much after that, but it does make it easier all the same So all we got to do is open the back up get this thing and run it and tweak it in to where we can maintain You know a close to a liquid of 100 degrees area is what I try to shoot for Obviously, you're trying to keep that suction up. I'll probably swing somewhere between 95 and 110 115 I just kind of watch combination my suction and my head pressure don't want too much to the point where it never Stays running you want it so that in mild temperatures, you know and stuff like this that the fan continues to run and doesn't cycle You don't want it to cycle too quickly to the point where it ends up taking out your bearings on your motor For a little shorties out here That's why I keep them around We got our gauge right there probably about 110 115 came on about 125 Usually used to set them mainly for like 275 area Just seem to be able to maintain that suction saturation temperature about freezing but that can cause a lot of issues Just too much of the swing and then it causes the TXV to have erratic feeding back and forth, so Crank it down just a little bit so we got it ready to go and Let's see where it goes in at now That's a little better. We can crank it down just a little bit more A little touch over Let's tweak it one more time, and I'm just gonna go ahead and go from there about our fan cycle switch going It's not shutting off while it's in this warmer weather, which is what you want You don't want to cycle me when it's 80 degrees out So just something to help make up for this cooler outside That way you don't freeze up your evaporator. Got everything buttoned back up all the screws in there We're not hitting anything on our lines there. I've got to spray it for leaks yet. Yeah, I noticed this that ain't Way it should be This part out here is good So now all we need to do is go in and check the filter on it and then scan that foil for leaks I bought here in TU All right up here we go See how under who put that there Yeah, that's makes it so easy to get in here in service So See if we can dig our way through here. So let's crawl back here should be able to There's basically going across the cooler here you see the line sets from the coolers and back here is the Other unit which it's got a collection of filters There it is All right, so we got the filter out and it's Not looking so good We're gonna shut this down. Hopefully they got breakers inside here. This one's cooling only so They didn't they don't have any Strips in there. So there's no breakers. So we're just gonna go ahead and pull the fuse which will shut her down Now we can get in there. We'll let it akimi late some refrigerant as it leaks and See if we can find this thing. We got one right here on the distributor tubes I don't know if you've ever tried to raise that brass before but you'll wish you've never done it Decent size one there and get on to our lower Let's go to just go to medium the coils in really bad shape They just need a new evaporator Which really be kind of stupid because it's our 22. So if you go setting it up for our 22 You might as well just convert it over to 410 a which means a whole new system So, yeah, it's it's not in the greatest of shapes. This thing's kind of kind of had a bad day The air handler looks like it is a sterile number 05 05 16 years old. I think it's had a good life and a commercial application that's lived in We're gonna have to get a new filter. It's at least working. We're just gonna come back with some filters, which is a weird one 16 by 24. It's good. It's an air handler. They're usually a little bit weird I'm sure there's probably more leaks A little of a coil wouldn't surprise me Found the leak real surprised. Just let them know what they what I know and kind of go from there All right, so we've got all the filters out here two that was Once I found above the ceiling and here's all of the 16 by 24s So we got that in there We're just gonna have to come back. I'm not gonna put a filter in so I don't have anything to even stick in there I think it's gonna wrap things up. We've got a leak obviously in the evaporator That we're gonna take care of we had a bad fan control We were low on refrigerant obviously because we have a leak and The other unit had low airflow. So Just another air conditioning issues Air flow or refrigerant one or the other so anyhow, that's gonna wrap it up guys If you enjoyed the video and you want to see more like it, please give it a thumbs up Don't forget to check us out on Instagram and Facebook and until next time.
