Thanks for posting. Seams like a lot of owners neglect needed maintenance? Also let us talk about the massive Restaurant closures? Your thoughts?

Under amping can mean it’s not pushing as much air. Was it the original condenser fan motor? And looking clean is deceptive. My personal 3 ton was acting funny and we couldn’t figure out why, so the tech washed it and voila the right pressures; in fact we had slightly overcharged it.

I like how it's super dangerous and we don't' want it leaking and filling up the space... So we just vent it into the space. lol. I got a good laugh for that one.

Great video, Chris, packing so much in. I love listening to your thought processes and find them informative and insightful. I have a couple of thoughts: What about using thermal imaging to record temperature rise in the condenser fan motor? It would show a bearing heating up and how hot the motor was getting even if the current draw was within allowed limits. The run capacitor that you replaced could have had intermittent failure. I've known capacitors to partially fail internally and suddenly not perform at all as required, usually due to a voltage surge or spike. When the power is removed from the capacitor 'self-healing' takes place and things appear perfectly normal until the next voltage spike and the cycle repeats. As the capacitor internal condition worsens it takes a smaller an smaller spike or surge to make the problem suddenly appear. Eventually, no more self-healing takes place and the capacitor goes bad for the last time. It's possible a temperature rise may be observed in the capacitor and thermal imaging may help discover this. Otherwise, the only way is to use a dedicated capacitor tester rather than rely on a function built into a multimeter. A proper capacitor tester can reveal far more about a capacitor than a simple measure of capacity. For example, the ESR or Equivalent Series Resistance of a capacitor is a very useful parameter in helping determine the internal health of a capacitor. Any reputable manufacturer will have the full specification of a capacitor available and if they don't I would want to know why and consider using a brand that does.

I LOVE EVERYTHING YOU DO FOR US!!! ❤❤❤

Pace yourself my friend. Like the infrastructure in the U.S. , quite a few pieces of equipment have outlived their useful life and you are the caretaker. But there is just 1 of you ! What the state, nay, the country needs is interested individuals like yourself to get into the trade and help things out ! Used to live in the Detroit MI area and in the 60's there weren't none air conditioning. Until we got a 10.000 BTU sucker for a window, . . ..on 60 amp service. Your skill with the modern machines leaves us mesmerized ! In this VLOG I believe you did the appropriate course of action. Cheers.

Hi Chris. Love your channel. I've been wanting to tell you for a long time now just how much I appreciate how consistent you are with how you do things and how you present information. To me, that is a very valuable quality for a boss, a business owner, a mentor, to have. That is one of the biggest reasons I absolutely love your channel! I know you always say you're not perfect, but your consistency is impeccable!! Thank You for your time.😁😎

Can I use r600 in a r290 system?

I think I can tell which one is the obvious

Don’t look in the attic! Pandoras Box “Polishing a terd” I love it!!!

Hi how are you wake in freezar tamprachar is sloy sloy wat rezan discharge 290 psi and suction 25 psi tamprachar is 0 to -1 time is 30 mint you not mind my inglash is week

Replace that joint. It is a fire hazard bad 😅😳

Mr show last night I have a question for you in your opinion do you think that the AC units of today are getting way too complicated with all their sensors and crap

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!
