Weekend No Cooling Call on a High-Efficiency System… Here’s What Failed

Added: 2026-05-11

[00:00:01]All right, folk got a no cooling car.

[00:00:04]Customer said that the fan was running, but he don't think the compressor turned on.

[00:00:13]So sad on the weekend. See if I get them up and going.

[00:00:19]>> All right, we got two units.

[00:00:27]I think it's going to be this one right here.

[00:00:36]That one look dry.

[00:00:38]This one look wet.

[00:00:41]I hope not freezing up.

[00:00:46]I need the right upstairs or downstairs on the unit.

[00:00:52]Matter of fact, I think I got the sear number here.

[00:00:55]>> Kind of weird, right? I mean, >> what it say?

[00:00:58]>> The fan is working. Everything is working. It's not cooling. It's like a capacitor.

[00:01:02]>> Which Which one is it?

[00:01:03]>> This one right here. Okay. Yeah. Okay.

[00:01:05]This one look dry right here. I can tell that one been running.

[00:01:10]>> Yeah. Let's hope it's a cap and go.

[00:01:12]>> Okay.

[00:01:15]So, >> the fan turn on or no?

[00:01:16]>> Uh, it probably got delay on it. You just turned it on, right?

[00:01:19]>> Yeah.

[00:01:24]Okay.

[00:01:51]Might have got it tight in here.

[00:01:57]when you noticed it.

[00:01:59]>> Uh maybe two days ago.

[00:02:00]>> About two days ago. Okay.

[00:02:02]>> Actually, it was so hot, right?

[00:02:03]>> Yeah. Yeah. What?

[00:02:04]>> Something is wrong.

[00:02:05]>> Yeah. Yeah.

[00:02:06]>> We tried to do the power circuit.

[00:02:08]>> Uh-huh. Oh, man. Why you didn't call me yesterday?

[00:02:12]>> Mhm.

[00:02:13]>> My bad.

[00:02:14]>> Yeah. It's okay.

[00:02:19]>> Still didn't turn on, right?

[00:02:21]>> Yeah. What it say on your screen? You got the Nest. It's blue.

[00:02:25]>> It's running.

[00:02:26]>> Okay. It probably has a uh a lockout on it.

[00:02:31]>> I can try to do the circuit if you want.

[00:02:33]>> No, no, no. Uh let me see what kind of alarm code on here.

[00:02:37]>> Okay.

[00:02:40]>> It's so hard to see. All right. So, we've got red one, two solid blink on red, yellow flashing, green.

[00:03:04]So we got red flash.

[00:03:22]We got to count the yellow flash.

[00:03:25]Could be. Oh, got yellow. Okay, that's it over there. Yellow. Go by that one.

[00:03:31]Yellow on one.

[00:03:35]2 3 4 5 6 7 8 Still didn't turn on, right?

[00:04:08]>> No, they got now get locked out.

[00:04:12]>> That might be an issue.

[00:04:15]>> Yeah, >> I know with the recent power outages also. I don't know whether that you know messed up.

[00:04:29]>> Y'all have some power outages?

[00:04:31]>> Yeah.

[00:04:33]So storm, right? The storm.

[00:04:34]>> Oh, yeah. That was about a week ago, though.

[00:04:36]>> Yeah, >> man. What? They put the electrical box on this side. It got it so tight.

[00:05:28]Yeah. Yeah.

[00:06:18]No, capacitor good.

[00:06:21]>> I said no, the capacitor is good. Okay.

[00:06:24]>> I was hoping it was just a capacitor.

[00:06:34]And this everything is on AI right. I was trying to trade this information to AI some troubleshooting that can help you as well says capacitor. So now you say capacitor is good then I don't know that's >> where AI is restricted man.

[00:06:51]>> So so what you use uh Chad or cloud or which one you use? I use a a Chad GBT.

[00:06:56]>> You like Chad GBT?

[00:06:57]>> Yeah, man. It's good.

[00:06:59]>> Yeah. Have you tried Claude yet?

[00:07:02]>> Yes.

[00:07:02]>> So, I just been dibling with it. But Chad GBT, I love Chad GBT, but Claude is kind of >> really >> Yeah.

[00:07:11]I I'm I'mma try Claude, though.

[00:07:14]>> Okay. Still there's a restrictions, right? Because beyond that, you know, I think >> Yeah. Oh, yeah. Well, yeah. Yeah. Yeah.

[00:07:20]No, you're not going to be able to trouble you. You going to need a meter and stuff to troubleshoot.

[00:07:24]>> Exactly.

[00:07:25]>> Once it gets in the last line, call the expert.

[00:07:28]>> Yeah.

[00:07:44]>> Take this. Uh because it says running.

[00:07:53]>> Yeah, it got a lock out on it trying to protect it.

[00:07:59]>> The thermostat calling for it, but uh it's locked out. Got a control board in here.

[00:08:04]>> Okay.

[00:08:04]>> Yeah. So, it's not going to let it keep running.

[00:08:08]>> Okay, that makes sense.

[00:08:11]>> I got pressure.

[00:08:13]>> Whenever such things happen, what I did is like a power.

[00:08:18]>> Yeah.

[00:08:23]Turn on the circuit breaker. Right.

[00:08:27]>> Yeah. You can do that maybe one one time, but I wouldn't keep doing it if it don't turn on.

[00:08:32]>> Oh, okay.

[00:08:40]All right. Come.

[00:08:44]All right. Fired up.

[00:09:07]We long prison.

[00:09:12]It's going to be long prison. It look like a f.

[00:09:24]>> Yeah, we low on refrigerant. Let me show you.

[00:09:27]>> Okay.

[00:09:29]>> Yeah, it's going to go off on low pressure.

[00:09:32]See at 33, they got to be above 100 PSI.

[00:09:35]>> Okay.

[00:09:36]>> Um, >> so why this low pressure stop?

[00:09:38]>> Got to leak somewhere.

[00:09:40]>> Oh my god.

[00:09:41]>> Yep. Yep. Yep.

[00:09:44]Yeah. See, feel that. See, it's cool.

[00:09:46]It's supposed to be warm air blowing out of here. Yeah. It's going to shut off here in a minute. 35. So, it's getting a low pressure alarm on here.

[00:09:57]>> Yeah. So, I'm going have to come back next week and do a leak search on it.

[00:10:00]So, we we're not going to have time today. I got to pull everything down, get electronic leak detection, and see where it's leaking from.

[00:10:05]>> Okay.

[00:10:05]>> Uh nine times out of 10, it it might be leaking in that evaporator coil up there. Uh that's usually where they leak at.

[00:10:12]>> Okay.

[00:10:13]>> Yeah. Unfortunately.

[00:10:15]>> Okay. That's what you know. I think that makes sense. So that you know >> what needs to happen next week, right?

[00:10:20]Rather.

[00:10:21]>> Yeah. All right. So this thing going off on low pressure. Get them charged up.

[00:10:25]This like I say at the weekend.

[00:10:33]See 59 56.

[00:10:36]Take a picture of that real quick before it go off.

[00:11:06]Low suction pressure.

[00:11:13]really low, too.

[00:11:22]All right, close this up. See where we at.

[00:11:30]Yeah, we low.

[00:11:44]Go ahead and check this. Uh, shoot.

[00:12:08]I've added insulation to this >> last time you came in.

[00:12:13]>> Uh-huh. Oh, yeah. I see.

[00:12:14]>> Yeah. They have >> Yeah.

[00:12:16]>> top of the insulation as well. So, >> they put that blow in.

[00:12:21]>> Yeah.

[00:12:22]>> Yeah.

[00:12:50]Yeah, that's it right there.

[00:12:54]That's just a quick way you can do a leak search.

[00:13:01]See 14.

[00:13:04]That's how we know a leak from the evaporator core.

[00:13:10]See that?

[00:13:14]You stick it in the drain line. Hey, know it's evaporated core. I got to get it replaced.

[00:13:28]19 parts per million.

[00:13:43]Still want to open it up though.

[00:14:23]TXB on the outside so we know it's not there.

[00:14:32]Still getting wind right there.

[00:15:11]There's a lot of insulation up here.

[00:15:49]You see the refrigerant around here?

[00:17:19]Oh yeah, I see all the oil in the back right there.

[00:17:26]See the oil back there?

[00:17:30]Let's see it right there.

[00:17:34]Look. 3145.

[00:17:37]That's it back there.

[00:17:45]trying to see if I can take pictures.

[00:18:01]That's it back there, folks.

[00:18:12]And something got a bad leaf back there.

[00:18:19]You see all the oil residue on the back back there.

[00:19:00]You hear me? Yeah. It got a bad leak back there.

[00:19:04]Yeah. So, at least we can pinpoint it, though. I got video of it, too. But it it you can see all the oil and everything back there. So it it's going to leak back out.

[00:19:18]>> Huh?

[00:19:19]>> No. No. Not at all. No. No. No.

[00:19:23]You can run it. It's not harmful.

[00:19:30]Huh?

[00:19:32]Say that again. You got to uh replace this coil. Uh yeah, minimal. You got to replace it >> cuz it's aluminum. It's not copper. You You can't braze it.

[00:19:43]>> Yeah.

[00:19:50]>> AC, right?

[00:19:51]>> Yeah. Just Yeah. Yeah. Just fire the AC.

[00:19:54]It'll get you back up and running. Yeah.

[00:19:59]Like I say, it's a big job though. But >> yeah, >> we had like tons of issues there, but now it's like good.

[00:20:17]>> But yeah, now I feel good up here, too.

[00:20:19]>> Okay, I'll I'll just give you some space because I know it is pretty tight up there.

[00:20:24]>> It feel good up here, too, though.

[00:20:32]Yeah.

[00:20:34]>> Yeah. Like I say, at least we don't have to speculate now. We know exactly where it's at.

[00:20:41]>> The coil cannot be fixed. Replace.

[00:20:43]>> Yes. You got to replace it. Can't
