 Okay, so here on a heating issue call, we've got us a 2015 unit here that's three tons of cooling slash heating, and they're saying it's not heating. I can feel just a slight warmth there on the discharge slash hot gas line, and I checked the air filter and it's fine. So let's go pack in here and grab the tools and see what we can find out's going on. So basically, filter's fine, fans running, so why the electric strips didn't come on, it's beyond me. Got a little bit of a shake going on there. Okay, let's, I'm going to put my gauges on it honestly, it's going to jump right to it. Just really no, no real warmth coming out of that thing, so let's put the gauges on and see what we get. Alright, we're going to take off the hat here, it's not, not really good for keeping my ears warm when we've got the snow. Outdoor temperature today is probably about 18 degrees I bet, something like that. Let's see what we've got going on here for pressures, I can just about guarantee you from my experience that it's low on refrigerant, like bleeding it that way, that way I know I'm clean up here. Alright, so let's see what our chart says here, alright it appears it's gotten a little warmer out here, it's 25, so, and of course, you know that's just the way it rolls, that's the way it rolls. It's going to defrost right when we're ready to get started, got to love it, got to love it. So this unit is a 36, like I said, so indoor temperatures in the 70s and outdoor temperatures between 20 and 30s. Let's get this stupid thing out of a defrost, which I don't know why in the world it thinks it needs it, this obviously is not an on-demand defrost, so we're going to speed this up a little bit, usually that would work, yeah there we go, it's slow, I'm used to immediately switching over. What did we do here? I just taped it kind of together-ish, is this two stages, is it? It sure looks like it might be, it's building a little bit of pressure there, I don't want to jump the gun too quickly here, but like we said, we should be somewhere in that 300 to 325 mark area, and then somewhere around the 80 to 60 suction, yeah we're off a little bit there, curiosity, see what our sub cooling is, sub cooling technically is 23, that's going off the liquid line there, which liquid line is running 60 degrees, coming back from the evaporator, and we got 83 there, so that's 23, huh, it's not extremely low if that is what's wrong with it, it sure is seaming that way, that's a lot warmer than what it was, I wonder if we got something weird going on here, can't help but wonder if we had something to do with the thing going into defrost like it did, and usually that defrost control I think closes, it's normally open, so closes when it starts to count, it's going to open when it's warm again, so drop of temperature, see how we did right by yanking that, that kept it out, so usually with like a Linux board, if I had the speed up terminals it would have kicked right out, but evidently not with this one, so let's just run a little longer here before we jump in to add anything to it, which I hate charging these things in the winter, but like I said I bought guarantees as we scan that evaporator, we're gonna find a leak, I guess one of the things that kind of bothers me is why the electric strips heat didn't kick on and bring the temperature up, so we probably got more than just a refrigeration issue, which is kind of concerning, let's go ahead and see what our actual discharge temperature is off that evaporator, so I finally found one of these in duck work somewhere, and they're kind of slow about getting to the temperature, holy crap, everybody made fun of my mom that I normally use because it's been a little bit, there's reason why, slow that thing is, and why am I getting 58 degree air coming back through here, I mean it's got a lacious amount of cold air coming back to the furnace, 58 degrees, I mean it ain't no 58 degrees inside the house, they got a wood burner running in there, so 58 degrees coming there, let's see what we got up here, let's just see what we got, it's probably why the freaking pressures are so flipping low, all right so we're up here in the attic, you can see right there some of the plastic is ripped off that return, a lot of it actually, what the world's going on with that, it goes down there, so we have to follow it, which is not really easy to do, but yeah this insulation crap's got some issues, that's the return air, I mean that's that's not very good, I don't know who sliced that thing, or if I just getting brittle, but that's not, that's not good, not good at all, there's another one for return, it's all chimichangud, that right there don't look good on the side, it don't look like a good 90, well it's gonna be real good to get down in there, not fall through the ceiling, so I can't do that with the phone, so we'll get over there and see what we can find, all right just looking at how they did this duct work, there's no way our people did this, this must have been existing, so this is some hack-looking stuff, you can tell the cheap stuff they used just deteriorated, it's completely missing off that, I've never seen anybody run it round to the end and then split off the end of a round with ducts coming in, so this is return here and there, oh that's great, look at that, magical wires up in the attic like that, that's nice, they don't really have that much insulation up here either, you can see the return there, I crawled all through there with all that sheathing, which I know ain't a lot of our value, but it ain't helping it, none not having it, but I mean all the duct work muzzles, if you're gonna fix some of it, muzzles replace all of it, it's bad shape, they really can use some new insulation, more insulation up here, this is like cardboard cellulose stuff, they do not have that much up here, so I don't know what all I can do to help out with that, I don't carry enough to do a whole house on the truck, so go ahead and crawl back over there and see what we can do with this thing, make sure it's working as good as we can get it, all right, but the only thing I can do with that is tape the thing back up, so at least isn't completely losing all of its R value, but that there, none of it's split open, even though it's missing it there and there, if you guys think it makes a humongous difference, I'm sure it don't hurt, but I mean I don't feel no air leaking out through it, but you guys leave a comment down below, but one thing I can do for right now is seal that, I don't think that's the, let's give me an extra 10 plus degrees of gain in the return, but go ahead and get that done real quick, you can see how much that ate up and that's what it looks like which ain't pretty, but at least holding the insulation together, not just the spiral wrap just being shown, so I don't see if it makes a difference, but I'm telling you, good chance it wouldn't be a bad idea to replace all of it, but you know what kind of money that's gonna cost, so it is what it is, gonna go ahead and go down there and see what we can do with this, all right, I think it was 50 something for me at 61.3, notice this isn't insulated from what it sounds like, at least that is, and when this door is shut in here, it probably keeps it a lot warmer in here, the present is bad, but that's not nothing to write home to mama about, you can tell electric strips are probably on, all right, so now that we know the incoming temperature is more like 60, we'll come over here to the 30 and 20 mark, should be between 262 and 286, so we aren't off by much, unfortunately, I'm gonna say he's just, he uses a wood burner most of the time, so it could be as high as 286 if you wanted to go with the 30 degree mark, 65 on the liquid temperature, 85 for the condensing temperature, 19 degree subcooling, not too far out of line, what I'm guessing, so I don't think that's gonna make a big difference, we could try and hook in some of the strips so they're not running, see what the actual true rises across it, I would estimate probably today, you'd be lucky to get somewhere between 14 and 17 degree rise, all right, so we're checking them right here, and once again, as always guys, don't do this if you're not trained, not responsible for you killing yourselves and getting electrocuted, these are for entertainment purposes only, so all my strips are working, I just basically covered door up, see what we got, so we got basically, looks like 15kW there, yep, that's what we got, so electric strips are working just fine, wiring looks okay, there's our speed settings, comfort is what we got there, 10,000m, strip heat there, pretty much made this thing brain dead, can't even stand on low, so I mean it's wired right, set up right, the fridge is pretty darn close, I'm gonna say there ain't nothing wrong other than the poor duck work, everything looks pretty good, yeah so we're running 110, 111 up there, was 60, so 70, 80, 90, 100, just 40, there's 51 degree rise, so the extra strips must have came on, go out and check our pressures again, see where we're at, I don't like going off pressures only, we can give it a little squirt but I don't think it's gonna do much, don't think it's gonna do much at all honestly, especially with the sub-cooling looking like it's about there, you really aren't supposed to charge these in the winter time, it, what's this normally run for sub-cooling, 13 for a for summer time cooling, we're running about 20 and heating which they never usually tell you that, but sub-cooling, sub-cooling in all reality kind of gives you a good idea if you do it more often, so we'll weigh in maybe a half a pound, something like that, see where that puts us at, I don't want to go extraordinary here and go stupid, this beast probably holds a crud ton, yeah 13.7 pounds, I'd be kind of tempted maybe to check that evaporator for leaks first, let's do that for precautionary reasons first, this is 2015, that's an aluminum coil, I haven't had too many leaks on these, have had leaks on the TX-V, I'll do a scan on it real quick, but this is not the one I was thinking, so it's probably fine, I'll do a scan real quick, let it build up some residual refrigerant if it's leaking any, all right so we made some changes in there, the thermostat was set up for three degree differential for the auxiliary heat, they had I think auto mode for first stage to second stage, I set it for 10 minute minimum or maximum runtime before it up stages to second stage, basically left the auxiliary at three degrees, changed it to the setting where anytime it's below 40 degrees, carrier has an option where you can shut the fan G signal off and it'll lower the fan speed so that you get better heat out of it when it's colder outside anytime below 40, that will get you a little bit better air which obviously it's already doing some of that now, so right now we should be on first stage and we're at 70 ish so second stage should kick in here in less than 10 minutes and then it'll still be a three degree lag for the auxiliary heat to kick on, customers are aware of what's going on and he just basically said as long as he knows what's going on and what to expect that you know he'll deal with it when he gets back from vacation, there's still about 61 and a half there, we're 73 here, still waiting to see whether or not first or second stage just kicked on yet which should be or real close to it here, so right now it's kind of sad, I mean 61 and a half minus 73, about 12 degrees, so not 11 and a half not real impressive, I would say we're definitely in first stage, look at that head pressure it's only at 235 and we had a little bit of a leak when I walked away, my hose is leaked around the fitting there, hopefully that's didn't lose that much, you can see we got quite a bit of oil which is great, let's see if there's some cooling in, yeah it's only nine, I don't have the suction probe hooked up because it's not worth checking right now, give it a couple more minutes it should jump up to high stage, it must have just changed, you can see the pressure is jumping up pretty quicker, stage two is now on, we're still at 61.5 with 81, that made a little bit of difference, that's a lot better than what it was doing, so combination of the fan speed because that's raised my head pressure a little bit, so if you subtract those two, 61.7 minus 81.1, let's just round it to the nearest degree, let's just say 62 minus 81, it's about 19 degree rise which is pretty good when it's 25 degrees, 23 degrees outside, a lot better than what mine's doing, so I think we're gonna go ahead and leave it there, I gave them a little bit of a squirt just to make up for what I lost when my hose is leaked and I think that's gonna wrap this one up, basically make sure that you guys check all of your supply and return temps, you know going off to supply only would have screwed me if I would have not noticed that the return air was warm, I sometimes do that more often when I'm in a situation out here where it's a garage and the attic is where the ductwork has to go through, so it appears to me that it's working pretty good and always double check your thermostat to make sure the programming on it's set correctly, so it's gonna wrap this one up guys, just be aware of your surroundings and always keep looking until you find all of the problems, if you guys enjoyed the video you know what to do, until next time we will catch you on the next one
