 From looking right here. It looks like they did everything right So there's a chance that maybe we have a TXV acting up possibly and it's holding it back We'll just have to see here. I don't Don't know for certain what it is just yet All right guys, so we've got a two-story house here Basically, it's got two systems both of the same size last year. They said it worked just fine So I get here. I check the filter I check the Coil, you know, make sure everything's working upstairs. The problem is it works one day, but when it gets hotter it starts to act up, so I Get the gauges hooked up to see what's going on and What you can see here is we're running between 5 36 and She'll jump up even higher the outdoor temperature right now today There's about 91 degrees and this is going to peak up there again So I want to show you what happens when these things are overcharged. You're about 50 degrees over ambient Now your super heat is 12 degrees This just goes to show you TXV does its job. It basically just keeps track of the super heat. It doesn't care So it's holding that refrigerant back We're just stacking it in the condenser there and then your subcooling goes skyrocketing high So what we're going to do is we're going to yank some out of this thing And we're going to see how much it actually is overcharged by to kind of see where we're at I'm going to head and just use the probes here Just dump it in our tank and take this thing down a little bit just to see where we end up at the required subcooling is 10 degrees so Say the least we're just a touch high. I'm going to pull a little bit out here and kind of just see where we're at Total charge on this thing's only three and a quarter pounds For this one here. We got a 55 foot line set And they added one pound ten ounces generally these things are charged for 15 foot so if you take 15 foot off of 55 55 minus 15 which is pretty cut and dry. It's 40 foot take at times point six ounces Which is what your three eighths line is should be about two pound or 24 ounces So subtract 16 off of that. I'd be one pound eight ounces and they added one pound ten ounces So they've added about the right amount For it. So there's a chance we may have some issues with this unit now I did worse to condenser coil when I got here first thing I did because the backside was pretty dirty and You can't really get any good clean measurements unless your coils are clean I mean that's just pretty cut and dry don't even bother trying to set up your super heat sub cooling all that jazz Unless your coils are clean so From looking right here. It looks like they did everything right So there's a chance that maybe we have a TXV acting up possibly and it's holding it back We'll just have to see here. I don't I don't know for certain what it is just yet we're just kind of Starting out at the beginning point here. We've taken out eight ounces and We've got still a 32 degree sub cooling Fortin's kind of Irrational as far as the way it Reacts you rush this stuff a little too quickly and she'll bite you in the pooper Set it right there Maybe a little more accurate Yeah, it's a little bit better So ninety seven hundred and seven hundred and seventeen. Hey look at that Bill Russell out of new photo now. We're at a 25 degree sub cooling So we're still high on our head there our super super heat still hanging right in there at 12 Subcoolings came down to 27 We've removed 11 ounces so far I'm gonna let it stabilize a little bit. We'll probably have to take a little bit more out Now one thing I do want to mention right away You can see where I sanded it on both sides of my filter dryer The first thing I did was check a drop across that and I had none Usually they say up to three degrees still going just a little bit further yet Pressure is looking a lot better. You notice. We're not seeing a lot of swinging on the high side or even the low side generally When it's massively overcharged you'll be swinging up and down up and down Oh, I didn't check the beforehand amperage, but the compressors at six point one to six point two Which is pretty good And then far as the fan We're rolling it right in there at point five point six right. There's ten. We're gonna let it stabilize for certain and Go ahead and take our temp drops. So there it is loving It's feeding a little bit there super heat if you noticed It was 12 to 13 before and now we're 14 Still need to double check this downstairs one just to be certain that way you don't come back later for You know same thing that would be bad So we went ahead and got the probes installed I'm not real impressed with the split, but this is in the attic and I'm not able to hang these on the plastic registers real well Got a 12.6 degree drop across the coil I'm gonna probably place the probe in a couple different spots that way. I know that it's not just You know the systems fan maybe going too fast or whatever This is probably the easiest I've ever seen to get into an attic Which is kind of nice for being mad at Not every day. We got to get up here So we actually have basements here So we're gonna jump drop this fan speed down notch It's I think it's a default high speed So we're gonna try see if we can get a little better dehumidification It is an ECM motor Should be easy to change this thing right around We can get into it here Heat cool cools on White the hell is white. Yeah gray. I'm sorry Gray is cool. So I'm gonna assume that gray is probably the highest blue is heat So we're gonna go yellow, which would be one notch down and that should help out a touch and we'll see if my Off-timing is here. I Hate furnaces that are set for the minimum. I always like to run longer Especially when you're horizontal or down flow. I'm gonna take it one under the longest about a hundred fifty seconds if you want to eliminate extra problem calls later It does not hurt on that fan a little longer That has been my motto for a long time because I've had several times where you're there and they have a big airbearer style filter or something like that and it's counter-flow meaning it blows down and The radiant heat just comes up and bounces off that filter and then ends up tripping a limit Then the furnace ends up locking out for something. All right, we went ahead and checked the sub cooling on this one It was at 12. So that's close enough for me. Usually you have a two to three degree differential So I don't know why the one was a little out of whack, but it's right now So I did have to adjust the fan down one more time So we're kind of waiting to see what it drops down to it's just now came on So we're gonna see what that split comes out to being now Just didn't seem like it one or two speeds was enough. So we went ahead and went one from the slowest We'll see where we're at. Hopefully we don't have something weird going on with the Unit that hopefully it's just maybe got charged in the wintertime or something like that. I'm not sure basically We start getting a good split and I'm gonna be happy and everything should be good to go We can get on down the road to the next call. So air flow is still coming up pretty strong not horribly bad So that's good. It's gotten up to 13.6 13.7 it's been running for probably about five minutes or so, but I Don't know so It's a lot better than what it was. We're gonna get a little bit more demonification out of it You guys like the video and you want to see more like it?

Have a good one. Good night. Bye. Bye God bless. All right guys. We got us a 15kw heater here. I wanted to point out something I found The customer called in said he was smelling something Electrical So I checked my amp draw on each individual circuit and we were pulling about the 21 amps per circuit Which is pretty common with a 5kw strip So I tested them one per time because it's an infinity system So you can test it one two and three while the way it's wired up It's one strip for low and then the outside two or you're high which technically they're calling it medium Well, I didn't have any trip breakers or anything else But once I pulled out the electric strips I wanted to point something out here as you can see They've broke and they've literally welded themselves To it you can see that's welded to it Well, the reason why it didn't break the reason why it didn't trip the breaker is because this is a resistive short to ground in all reality So basically it would have been about 120 volts to ground in all reality because it only had one side of power Here the way this is broke reason why we didn't have Amperage on it when it's shut down Your one leg comes through and is wired directly to your Breaker well that breaker leg comes up Comes to here and it was broke there. So that's your constant hot leg because they're only breaking one leg here So this leg obviously couldn't get anything to ground or through the coils. He had no amp draw at all But on your leg that's broke between your relay here that breaks the other leg just one leg It was actually going through and was shorting the ground Well, you wouldn't have anything because the relay opens up when this unit shuts down So technically you wouldn't have any smell when the fans not running, you know far as it just sat in their smoldering or whatever And like I said because this stuff has got resistance to it. It's not the same as a dead short This is not just regular wire. This is a special resistive resistive element type wire so That's something I wanted to point out for you to always visually check Your strip heat if you have something weird Going on far as a weird smell or something. So it's just one of those oddities there I just wanted to point it out real quick just a Quick tech tip, I suspect you could call it that and something to keep an eyeball out for You
