Didn't yawn, but I *felt* the tired.

Thank you for the stream Chris. Hope you are doing well. Have a good night.

2:28 That's great to know. I'm a firefighter and been on AC calls like that. Typically we don't open units unless there is active fire. We're not trained on opening units and not sure what we're doing or what potential problems we can cause doing so. If it's nothing active, we're trained to disconnect power and tell the manager to call their AC repair person. Don't want a business to say we messed up something and try to have the FD pay for a new unit lol. Now we do have a few guys that are electricians and or HVAC ppl.

Ive seen out of spec caps run the fan backwards. Also seeing light through the coil doesnt matter on a micro channel as much as tube and fin. Also good to check the pressure switch itself. I block off coil and watch guages to see if switch cuts out prematurely. Good stuff👍

Came across this same unit today,icing up right after the drier,pulling into a vac...new drier time

Love your channel. I like how you put everything in simple terms.

Great video. Thank you for sharing

I am gonna guess AC is dead because of 1 of three factors 1: some idiot messed with the unit(either during cleaning on the rare customer who does the required maintenance, or just an entitled manager who should not fuck with the thermostat) 2: environmental damage(California is sandy and is like all human lands, full of things disposed of improperly that can ruin motors by jamming them with literal garbage 3: the ducting or some other factor did not match the unit, which has caused it to operate outside of airflow and load conditions(often due to failure to keep air intakes clean, or resize ducts when upgrading unit ratings suprise me HVACR, show me someone who kept their unit in ideal conditions and it is 100% dead to JUST age

Could it have been an overamping compressor that could’ve caused the overload ????

You guys never do heating related stuff?

Chris, that's a three-phase unit? Are the blower motors three phase? Are the fan motors three phase? Three phase motors DON'T need start capacitors, and three phase motors DON'T need run capacitors. Are the phases correct? Not just running in the correct direction, but are the three phases in the correct sequence? I'm pretty sure you own a special meter for this (remember this is different from motors turning in the correct direction) "The phase sequence of three-phase electricity is the order in which the three phases pass a reference point, usually the red conductor first. The standard phase sequence in most countries is red, yellow, blue (RYB), or 12-4-8, which corresponds to a clockwise rotation:"

Work at a restaurant. Either the BOH or FOH AC works. Usually never both. It’s hot in Tennessee.

Have always loved your content. Keep it up!

Manually checking bearings on motor,and using thermal camera on it,could help,hate leaving and getting called back,because it overheated .thanks for the video.

Loving the videos mate, greetings from Melbourne Australia.

I made it about 3 minutes into this video and my sarcasm meter is broken... It really doesn't take much more time to do it right and to clean your mess up... Some peoples kids man, I'm telling you...

Yes, you made me yawn, but it's close my bedtime😂

In the HMI, pressing the top two buttons. If you went into factory settings, temp sensor config, temp sensor 1. Assignment. Preset. Sets the room to 75 degrees factory Would have saved a lot of trouble

I would have done the under load test with that old cap. I think the swap was a good idea and proper fix given info. Meg the motor if you have the means.

Hi Chris!. These intermitent problems are a pain and sometimes the hardests to solve. I'd have changed the fan motor relay as well (cheap). What do you think about measuring condenser motor winding resistance with a megohmeter? Thanks for quality content you share!

What would you do for a r410 unit that has a low side of 140, a high side of 310 and line temps are almost equal in temps(71 and 76)? I want to learn.

Yawning! Stop.

Yes, you made me yawn! 😂

Yeah, I’ve found if the caps are going bad the wind can help start the motor and you’ll get intermittent problems, I always make sure when I test the condenser fan motor and suspect a cap the blade is stationary.

I am not a HVAC technician but I know how heat can affect electrical components changing the cap was a good call also when you are good you gonna stay busy since you are so tired that means you are good

you're exhausted ? you need to think about you and give a little less

Chris, try to take care of yourself. You can’t help your customers if you get burnt out. ❤ Sending love from Australia.

Great job Chris has always.

Buenas tardes Chris, como siempre un excelente trabajo y con todo el ánimo de salir adelante ésa actitud que todos deberíamos de tener es admirable en tu persona. Por otro lado si te miras cansado y no me hiciste bostezar Jajaja, Saludos y abrazos a todos ustedes deseando que estén bien y que tú descanses para que recuperes energía. Desde Coacalco Edo de México.

I feel ya. Been crazy so far this year.

The tone in this man's voice I feel like he's like a er doctor on cooling heating 💯

Quick question, why are we not worried about the suction saturation at 33'f? Sorry for asking because I must have missed something in the explanation.

Another great video Chris. Thanks for sharing

You're right, this summer has been a doozy. Between business increases at Coffee Franchise (and the doubling of staffing levels on every shift but mine because "you never get busy in the afternoons"), car repairs, and crazy weather (thunderstorms, prolonged high temps, insane humidity) I'm already wiped out. I wanted to fix my rear brakes on Friday, but my legs were killing me from Thursday's business, so I had to wait until Saturday. Today, my legs aren't happy with me over yesterday's brake job, and right now walking/standing is excruciating. It's yet another reminder that I'm not as young as I used to be! I'm now telling the twenty-somethings I work with to pick a field they enjoy, work as hard as they can at it, and bank as much money as they can while they're able to, because there's an invisible clock ticking for each of us, and we never know when our bodies are going to tell us it's had enough. But I always add the caveat that "burning the candle at both ends" eventually leads to burn-out, so try to find a healthy work/life balance. Advice I wish I had been given at that age.

Chris if this is at the same place all the time where the 120/208 is consistently low, someone needs to call the power co

Sweet, another video. Thank you.

4:45 Who did they get to make that app? Why would they put all that goofy slow worthless animation in an app meant for field techs? They must have gone with the cheapest third party possible to make that abomination. Meanwhile, manufacturers, please just put your info on the web where I can search it!!! These apps are terrible!

tip - stick labels on the units for dates and purpose

Haha, your brain works like mine does! Remembering some random completely obscure detail from years and years ago that ends up saving the day! Love it!

So there wasn't any high side temp or pressure controls other than inside the compressor? A manual reset control would have protected the compressor.

Id like to see how that RTU runs on a 100+ degree day. I think you did your due diligence. Definitely needs to be monitored.

Very helpful!

It very well could be the low voltage issues. I guess there's nothing you can do about that. It's an external infrastructure issue. And yes you made me yawn 🥱 Lol

I've been on the roof for the past 2 weeks doing Carrier controls economizers, etc. They suck

Where do you get the cutable filters

How are you able to turn off unit and not trigger the duct detectors?

🙌🤘

Funny how you have undervoltage issues there. In the UK, where the target voltage should be 230V, the abundance of solar and lack of AC demand means the voltage can be seen as high as 258V where I live.

You need to keep a record on all the units you work on

48 thumbs up
