A comprehensive HVAC system inspection involves systematically checking multiple components including motor amp draw (comparing actual readings against rated values), capacitor specifications (verifying microfarad ratings match system requirements), electrical connections (ensuring proper conduit and secure connections), and system pressures (monitoring saturation temperatures around 40°F as an indicator of proper refrigerant charge and system operation). This multi-point diagnostic approach helps identify potential issues before they cause system failure.

Checking On A System For New Customer!Hinzugefügt:
Hey guys, the call I'm going to right now is actually a call from social media. One of my um viewers on social media hasn't had a great experience with the local companies and asked me to come out and just give him his system a good once over, maybe a preventive maintenance because he don't think they did a good job.
Stick with me.
uh maybe three or eight years. It got installed uh August of 18th.
>> Uh-huh.
>> And I think about 3 years ago, I was out of town and we had to have a passenger.
>> Okay.
>> Other than that, that's the only issue we ever had with it. Um, I will tell you I think that they that's been that way since day one. Um, they uh hard, but no issues. Uh, I think they must have left the screw loose cuz inside you don't hear it vibrating, but inside you can kind of hear a little bit after they changed the bathroom. I was wondering if they left the screw loose.
>> All right. Um, well, I'd like to start inside.
>> Absolutely.
>> And work my way out here.
>> Perfect. Like I said, we're having no issues. My big thing is I travel so much and I've gone out of town. I just don't want the wife to have issues when I'm gone, you know.
>> Okay, makes sense.
>> Pastor need to replace it. You know, we're getting close.
>> Yeah, that looks good.
>> I just changed it maybe two weeks ago.
And forgive me if you need to move any stuff around up there. Make yourself at home cuz I know there's something probably in your way.
>> That's okay.
>> And there's a light switch. Why'd you get the top of the stairs on your left hand side? There's a little light switch, little >> incandescent bulb.
>> Not much light, but a little.
>> Let me see what we got up here.
>> You want your bag?
>> Um, not yet. I got to come back down.
I'm going to get some algae tablets and stuff.
>> I got you.
Plenty of room up here.
We do have us a float switch right here.
All right, let's get on.
Let's get our algae tablets and I'll be right back.
Man, that was kind of loud. Got to remember to check that when I come back out.
We are very likely going to have a X13 motor on this.
I know y'all probably can't hear me very well. I'm going to check the amp draw on this motor real quick and um and then we're going to check the blades to see if they're dirty because I'm seeing some buildup right here.
1.6.
Motor is rated at 4.1.
And yes, that amp draw can change dramatically depending on static pressure.
I think that's pretty good.
Very good actually.
Read what size wire this is.
There it is. Right there.
That's a 10 W with AWG 10.
I'm sorry.
62 with 10 grand. Okay.
I was fixing to say that's kind of small. It's just um a different color than what I'm used to.
I'm going to turn this off. Leave it on cool and crank this down.
First of all, that right there.
That looks like a regular PVC connection.
There is a chance I can glue that.
Why don't we try it?
This is one of those. I don't know if this is going to work or not. If not, we can put a new end on it.
Right now, I'm still holding it. So, oh, it just slipped.
Oh, no. That ain't going to work. I'll deal with that electrical connection in just a second.
I got to get some of the screws off my magnet.
Lovely.
We got a trader cat missing man.
Got one of these uh amrads on here.
It's got multiple options.
Looks like that's supposed to be a 70 and5.
Y'all forgive me. My magnet was on my chest was sticking to the tripod.
I know I've got power pulled.
But let's make sure we don't have power.
No power. That contacttor looks good.
So, what I'm going to do here is switch to microfarads.
Go to my C, which is my run winding 5.17 and over here to firm 68.25.
That's a plus or minus 10%.
That's still going to be good.
I think the only other question because this customer is just worried about that capacitor is when I open it up, look inside and make sure that's the correct size for the compressor and condenser fan.
There is something I want to see on this because we heard that bang when That bang when it shut off.
Forgive me. Digging in too much.
I'm trying to grab the hub and hold it still and grab the shaft and hold it still and see if the hub moves. But I can't hold I can't hold the shaft still with that.
Thanks.
All right, I think that hub's in good shape.
Sometimes this hub can begin to spin free from here to here. It'll move between these two pieces and when it shuts off, it'll make a bang like that because it's impacting the other the other side of its capability of movement.
I don't think that's what's happening. I think the noise we heard was the motor itself. We have a five microfarad. So, that was correct. Quarter horsepower.
I'm trying to read RPM somewhere and I am just not seeing it.
I have volts, hertz, horsepower, RPM, 11105 will Look, come on.
Oh.
Oh my word.
Holy smokes.
Let me try to attack it from this angle over here.
Actually, I need a little bit of help like a stick.
Still have to stand on my head.
I'm probably dropping all those leaves right on top of my bag. It's okay.
All right. Now, I just need to get a picture of this name plate on this compressor.
And I'm doing that to see if I can verify rune cap. Looks like a 70. We're good.
One last check on this motor.
>> I think the bearings are okay.
>> There's a surprise in there waiting for us.
At least it's unoccupied.
All right. What I want to do is disconnect this one and this one. And we're probably going have to do that one, too.
Okay, those are my wires to my condenser.
You'll see why I'm disconnecting them here in just a second.
Give me just a second. Lose this. I've already lost one.
This right here.
See, this is 3/4. So, this should work.
Let me guess. The bottom of it turned into All right.
Now, forgive me. That thing is wanting to break. So, I'm fixing to let it break.
Got it turned just a little bit. There we go.
Holy smokes.
Nope.
Nope.
Feels like that's loose enough to come off.
There we go. Finally.
That is not the proper connection for that.
This is there are multiple different kinds of that looks just like a PVC connection and that is not a PVC conduit.
Uhoh.
Got to put this on first.
All right.
Here's the tricky part.
Getting that not just to slide on where it did, but up into here.
There it goes.
Now I can screw that on. It tightens up.
That's really all I need to do. This up here does not need to be any tighter.
I just need to remake my connections.
Let's do this one first.
This disconnect my power connections may be a little bit tricky because my lugs are wanting to fall off.
Let's do this one first.
Okay. And this one got work in the shade for the first few minutes of the day, huh?
>> Yeah.
>> Oh, heck yeah. You fix the uh the car has been there for 5 years like that.
Don't feel too bad this morning in the shade.
That's good.
You need a bottle of water or anything?
>> No, thank you. I'm fine.
Okay, I think we're good.
Put power to it in just a second.
got a rattle to it.
Now that it just got started up, first thing I want to check is these amp amp draws, especially on that condenser fan motor.
Because this is a heat pump, it's easy to identify which wire to check because that relay up there breaks common for the condenser fan motor.
1.14 amps.
fan motor 1.4.
So, it's within range.
And my compressor, I've got 9.2 2 amps.
And once again, let's check here.
Compressor RLA is rated at 18.1.
So, we are well within amp our amp range on both motors.
Next is to check pressures.
I can feel already that it's getting cold or Okay.
It is 73 72° inside and it's 66° out here right now. It's abnormally cool.
So those pressures, especially at these temperatures, at this saturation temperature is hovering around 40°.
And in all honesty, with all these new refrigerants that are out, if you're running in air conditioning, if your saturation temperature is around 40°, that is a good starting point to look for when you're looking at your temperatures and learning the new refrigerants. because if it's the saturation is at 40° um that that's a real good indicator that things are doing well. This customer did notice that the previous company did not put the shraider caps on or at least one of them. So, we're going to put shiny brass ones on there for him to see.
Okay, I'm going to put the cover on, look to see how convenient water is, and we may um just wash off the condenser, and we'll be done with this one. It's already very clean.
What I'm doing here is basically just rinsing off a a layer of pollen and dust.
Just keep an eye on that condenser fan motor. I'm when when it starts going, I'll give you a call.
>> Or if it or if it just stops.
>> That was my only concern out of everything. Capacitor. I even went to the compressor in the motor, make sure it's right size capacitor >> and then checked it. It was fine.
Connections are fine. Um amp draws are fine.
>> Pressures pressures. Everything's fine.
>> Good deal. I just hadn't had it really checked since it went in eight years ago.
want somebody to look at it.
>> Oh, that's >> rather be safe than sorry cuz when it's going to break it, I'll be somewhere in Atlanta or Savannah or somewhere 100 miles away from my wife.
>> She like, "Dad, it's not working. What do I do way happens, ain't it?"
>> Well, I'll leave you a card and something happens, you can call.
>> I got you programmed into my phone. So, >> cool deal. I do hope you enjoyed that video. If you did, how about give me a like and subscribe.
Check out the store in the corner if you want to be an ACIQ dealer. Um, I just installed another one a day or two ago.
I really like those systems. I'm not just saying it. They are some of my favorite systems that I've ever installed. So, if you want to be a dealer, check out the um link in the description and look for tomorrow's video because I'm going to be installing that.
If y'all know what it is, y'all know I've got a It's not going to be terrible, but I got to open up a system and try to keep this cool while I'm welding on it because somebody else didn't. Catch you on the next one.
