 Last time we had to stop short of installing the indoor units for my DIY home air conditioning system Because I ordered the wrong thing twice delaying the shipment, but not today. We've got one two three four Indoor units sorry that one's empty because we already opened up this one. Ah yes my lovely assistant Brian the electrician is going to help me put three of these so these are the cold side units with the Evaporator in them in the ceiling of my home, and I have no idea these are a lot bigger than I Expected just a little bit are these gonna fit between the ceiling? joists just We're gonna mount this I fix its mahi driver kit includes their quarter inch aluminum screwdriver handle with a magnetic bit socket Neural grip and swivel top and 48 driver bits check it out at the link below oh Yes Manual right off the bat wiring obviously goes here There's the refrigerant lines, and there's your drain and the drain is key because condensation and all that we don't want that just soaking through my ceiling into the rooms below for those wondering why I am DIY installing air conditioning in my house The difference in cost this is all together gonna cost me around five grand the quotes that I got back when I had it quoted Were anywhere from 20 low to 20 high to have it done professionally no offense Unboxing wise we've got the remote some batteries cable harnesses Fitting stuff like that we've got some insulated jobby here some work drive clamps presumably to put that on and I found this So each one of them comes with a fascia piece. This is a lot bigger than I expected I don't know it doesn't stick down very far Yeah so it's right flush with the ceiling like that and I think it's motorized because there's a Couple cable harnesses here, and I found one cool feature. I like you can go like this, and then it'll just kind of hang off these Stringy things and you can clean your filter like that, and it gives you access to the electrical all right So this will be fun to install yeah, especially when I get to play with fire. Oh What's the fire for soldering the refrigerant? Oh, okay? That makes more sense? I thought you meant to install this not this specific yeah The refrigerant lines going to this yeah Forgot about the other accessory boxes. We've got tubing for the drain line the neoprene the neoprene gunk that we're going to do something with adapter do datum a jigs and More tape okay, so we have our unit so with its mounting plates The idea is there's supposed to be ready rod going up but instead we're going to put a block of wood here and some of the cantras that we used and Run a bolt through with nuts and bolt it all together that way and then the two by fours in the ceiling Would be here so the now this will rest on those two by fours, and then we just screw it down and It's not going to go anywhere now. We've got to figure out where to put them So we're actually in two rooms right now This used to be the closets between two bedrooms one on each side of it But what we were thinking was since we've got the four ceiling cassettes We should put one on each side that way if we or a future owner of the house ever wanted to Close this back in they would have separate AC for both rooms We could just go like right in front of the closets because I'm also thinking in terms of when these are Individual rooms and where the beds might go you don't want it right above the bed that sucks So maybe like here in here yeah in the computer room We've got the contents of my attic to deal with in terms of the location for this I was kind of thinking away from the desks like over in that corner over there in the back here Yeah, as for the master bedroom. I was kind of thinking Here because this is gonna be the only heating and cooling for that bathroom as well So I wanted it kind of close by I would come out a bit to be honest you'd come out of it Okay, how come I'm just thinking in terms of airflow sure You don't want to be right against the wall. Okay. Let's do it. Let's cut a hole in the ceiling Which room do you want to do? Let's do the kids room first. It's the one I care least about I'm thinking if we can kind of get it You'll figure roughly where we want it and yeah, I just stick something up through and then looking from the attic We know where we want it and then we can cut the hole depending on where the joy sir. Oh There he is. Hello there buddy. So you just want me to go right up against the joist in line with that hole you made Yeah, okay. I'm trying on each side preferably. Okay. I'm working on it work faster. I'm I'm trying Okay Now I can't get it back out try again. Thank you Try again Thank you. Yeah. Okay. So there's your edges now what? Oh now we measure. Okay, there's a template see Template so should I screw into the part like over here where we're not gonna be cutting or should I screw in right here? And then I can go up and see how close we are You can do that if you want. I mean, yeah, this gives it long enough to go through. So did you hit wood or no? I know okay. That's a good sign Nope, okay. So that's a great sign. Yeah, as long as we don't hit wood on this side, they're not ready to rock Oh, yeah. All right. I think we should be good I'm sure we should be good. I'm sure we should be good I'm sure we should be good Didn't your mama ever tell you to be kind okay be kind to Dummies I should be able to work it through or someone should be able to work it through You should be able to work it through work it back and forth until it's through then pull the trigger and you're sure I'm Not gonna hit the mains Yes Awesome, uh, yeah, you're right against the joist. So just follow the joist Well, how do I follow the joist from here? Just go straight with the saw. Oh Boy do you need me to do it? No having way too much fun here I Got it. Yep, that's a hole, you know, it's cleaner than when you get Dennis to just put his foot through it With the the cover though because the cover has to extend into the into the drywall So we have to cut the corners there square them off anyway. Well, what's the point of that template then? I don't know doesn't make much sense to me while Brian fabricates some spacers I'm gonna square off these holes and try and get the vent to fit So stupid just utter waste of time, you know mark use the same block as our template every time stupid template that your stupid Just aim to go two sections Another to include a bad one because you're evil That's usable don't look that close to that one Andy. I widened the hole It was a full centimeter short on one side. So I freehand cut the shave down that centimeter. Nice. Yeah, I think I got it I guess we'll find out. We'll find out. So we've got spacers. Okay, cool and Brackets mounting bracket time. Whoa Just got to not fall through the ceiling. Oh no, I'm gonna get heavens through like so Leave it just a bit loose So that there with the washer hanging down I can fit on here Okay, so would you would you trust that oh, yeah, okay, you know I'm going anywhere I'm good But it's not gonna come unmounted at all Yeah, like the mount is metal just to be clear guys. The wood is a spacer. Yeah Yeah, I can rotate it Wicked wicked Here we go moment of truth time So these things we got to kind of get it in at an angle. I think here. Yeah Oh Come on. Oh, there we go So now we can swing these over and now it'll rest I'm just excited I'm gonna have air conditioning Okay, can you tell me if you think that blindy is gonna reach okay? Yeah, it's workable. Okay. It's not as ugly as I thought it might be That's good. Hey Brian. I think next time we should make the spacers a touch bigger sure so that this Snugs up a little bit more easily. I don't think it's the hole but it looks like I can't get up any further than this Kind of wiggle it around. Okay. Well in the meantime, this is kind of what it's gonna look like. I mean, it's a lot better than this so Yeah, so there you go, we're focusing on the positive here You guys missed day two of the installing evaporators side So we're gonna go ahead and put this in the freezer and then we're gonna go ahead and put this in the freezer evaporators saga we've kind of got a system now we made our own template and This is the last one and then we are good to move on to coolant lines and power and charging We're not that close You're there a Challenge we ran into here is that this area of the attic is actually 2 by 6 instead of 2 by 4 so our ingenious mounting mechanism was defeated meaning we need to use our backup ingenious mounting system handy-dandy ready rod and bigger blocks Yeah, now that we're done all the indoor units the next thing is for us to run the big main power lines for the outdoor unit That's the one thing that we still have to hook up for that There we go. Yay We're through with the fish tape in place now. We're ready to run our what is this eight gauge eight gauge? Yeah, yep eight gauge electrical wire So that's from the box here that goes to the tech cable over to my garage where it plugs into the panel Ah Oh, you're right that hurt. Yep, the roofs full of nails and I backed into it all good Well, if you leave a trail of red behind you will know why yeah. Yeah. Yeah. Yeah I need to put my hooky doodle on here. I'm down here ready to pull whenever Hey, hey, I got it. Yeah Oh, I just want this thing to stay hooked that keeps coming out. Yeah Two of the units are close enough to where the lines come in that theoretically Ryan should be able to attach Both lines to that one and that one then for the other two. Oh, we're gonna Extend the runs and insulate them and this will all be done in about 20 minutes 45 minutes 45 minutes We'll see. All right. Well not with that attitude. Let's go. Let's go happen to you. Okay, let's go. Here we go These fittings are good enough. They'll like handle being charged up with refrigerant and all that Well copper is quite soft and the end of the fittings are flared as well Oh, I see so it's flared and then the so the nut crushes the flare onto the rounded end So it kind of goes like that and the nut crushes it in well first we're gonna have to Pull some of this back. Oh, yeah, so I'll need a knife. Oh, yeah Kinder knife. Well, you know what is it gonna do the job? That's what I thought Okay, so We're going to all right. So now we cut it right the knife No, we cut it with the cut it with the pipe cutter Yeah, very good Linus. Yes, we're cutting this off for two reasons So see there's the flare I was talking about. I don't want to have to redo that I don't want to have to redo that so on the end of our extension I can take this whole piece and just solder it onto the end that also gives a clean end here that I can actually put a coupling on and Extend it I'll be in charge of the torch. You can be in charge of the fire extinguisher. Okay Yeah, I can do that as if it wasn't friggin hot enough So see it's just just red oh, yeah, yeah, yeah just starts to get cherry. Yeah blow that puppy on there Okay, no, no, I got this I got it Oh, yeah, these go on pretty easy Let me straighten that out a bit for you. How's that? Thanks Bud. No problem, Bud So I'm just cutting these so that I can put my little cable management strappy doodles in here So how much are these rolls of copper The three eights for 50 feet was I think 50 bucks and the quarter was like 40 Okay, so it's like a hundred bucks if we only use one of each Yeah, one of each size. Yeah, 90 ish. It's friggin awesome. Yeah, this keeps getting cheaper all the time Little does Brian know I'm not even gonna pay him Let's roll out some nitrogen. I want to watch your face line us The lines are finally all hooked up it's precious The lines are finally all hooked up. It's pressure test time. If nothing leaks we're close, right? Electrical to the four units and then the big run into the garage right? Yeah and drains and the drains We have to do the drains and the vacuum and the charging So this is high pressure nitrogen We connect it through the gauge set into the part of the system that is all new and that we've run We charge it up with nitrogen a few hundred psi then we go and we check all the joints for leaks Basically, we have to pressure test an evac each zone individually with the manifold I've got we can do two zones at a time So i'm thinking if we do a and d that'll be the two closest ones. That'll be quicker Yeah, and there's no solder joints or anything on those then right? So it's probably fine Probably then once we know that's good, then we can pressurize Yep b and c and test that here we go Oh, oh please tell me it's not threaded differently it is are you kidding me? Finally ready help Here we go moment of truth truth It's sunday again. So there's no fixing it if it's not right. Oh my god. It's not going on What's going on? Oh you dick The plan today is to pressure test the system Then get up and finish up everything we can in the attic before it gets too hot up there because last week was very unpleasant after everything's done We can add the last little bit of refrigerant because we extended the lines And we'll see how much nitro she takes and it's leaking already Nope This guy okay Okay If that's how tight they need to be then um any of the ones I attached upstairs are probably leaking too That's quite possible should I just go up there with the soapy soap and uh and a wrench I mean wait if the pressure's not going down then we should still check there might still be a slow leak that would show Up with the spray, but it might take hours to show up on here. Got it You want me to come up too or am I just gonna I think I can do it here I'm not seeing any leakage. Let me just check the other side real quick Trying to be real thorough. I don't want a leaky system Now that we've pressure tested you're hooking up a vacuum pump. So what purpose does this serve? It'll serve to evacuate any nitrogen that's left. It's a non-compressible The other purpose is to pull any moisture out. That's you know, that could potentially be in the system And It's gone. So then at least then this can sit out here and run while we do other things in the attic I still can't find what any of these additional fittings and like Plastic adapters and stuff are for and some of it's not even here in the accessories List so we'll use this stuff for the bulk of the drain runs the one end We'll sleeve right over top and then I have clamps so that can go over top we can clamp it And just use one short little section to come directly off the unit. This doesn't fit into the unit at all Okay, so there's got to be a an adapter or something to go with those Something to go with those That'll go in there and we'll put a clamp on there big relief we figured out how this stupid thing works So this does indeed go on the unit and then you kind of crush it closed like that And then you can see the inner part there, right? Can you see that? Okay, so we tried brian's idea of moving the worm drive clamp back a little bit Let's see if we can grab onto the tubing. Okay See we're good Us clamps on Now we can go downstairs. Okay, let's do it. Let's get out of here. It's hot I'm gonna do these And brian's gonna do the big heavy lumax downstairs but first Brian's gonna show me how to do these so that Is gonna go and clamp down there, right? Yeah Okay See I can do this Minus the electrician such a helpful man Get it get it get in there. Yeah, there it is All four upstairs units are done nice so moved a few circuits around in the panel to make some room to get this guy in so now We got to we have to sleeve it with some armor Because it's going to be surface coming down the wall and it has to be protected Once it's in the wall, we don't need the armor anymore And then we can enter it into the panel wire it up And then we can turn this thing on. Oh, yeah This is where we add more gas Yeah, so we added 47 feet of each length Yeah, hold on a second. You just have a scale Yeah, and then you just run the gas in until the scale says the weight the weight that we need Okay So And hook the disconnect up and go give it a try really that's it I mean not like that's it like this was horrible, but uh Moment of truth Is this gonna spark? This is some very room temperature air we've got going on here Um, I mean this valve is in i'm wondering if maybe we need to open that the other way We just broke it. Didn't we? Nope, if that valve is supposed to be open it's probably gone. I don't have any refrigerant flow Oh We opened up some things and uh We're hoping for the best now boys It's working Yeah, this this room is air conditioned af right now Ha This was so much more work than I thought I was gonna be putting into this This room I can already feel a difference for sure because it's got this window it gets so hot in here Oh Did I earn my water bottle?

That was a pretty good one. I I ended up getting hurt pretty badly But other than that it was fun. It wasn't that bad. It hurt a lot Hilarious Both of these are leaking. So we got a couple things wrong and I just want to give y'all a little update Okay, so these neoprene Packs we figured out what these are for these are for doing a real fine job of getting the fittings totally airtight So they don't sweat from the moisture in the air. So we got we got that sorted out And uh, oh also almost every single one of these joints leaked Where's the camera pointing? Yeah, there you go. Those ones we're gonna use some plumber's putty And then what we're probably going to do is go back and just get a proper like hard mount Adapter to bring this stupid thing down to something reasonable and then run that straight to our exits here because As it turns out it is a ton of condensation that comes off these things those long lines filled up in like two hours Oh, wait the last thing. Yeah, all these little straps and stuff Those got to be those got to be perfectly sealed as well. Yeah, no air. No air touches the lines
