I stayed up all night just binge watching your videos
They’re really good!
Lol
I do the same.
Wealth of knowledge here.
They're addictive. I can't watch just one. He's kinda funny, too.
Do you ever feel,
Like a plastic bag,
Drifting through the wind,
Giving Chris a hard night.
You are a true professional. I love your work ethic.
10:40 The headphones thing is also important in some areas for your own personal safety; always be aware of your surroundings. We sometimes work in some very sketchy areas and should know what's going on around us to the greatest extent that we can. Best way to avoid danger is to remove yourself from it before it happens.
I know nothing about HVAC nor had any interest in it until I came across your videos, well done!
I enjoy your methodology in the way you approach a problem !!!!! I’m not HVAC person just silly IT Engineer but really enjoy watching you solve problems and the way you treat customers. What’s right for the customer is right for your company.
That’s the way we do it IBM, customer first and don’t nickel and dime them.
Ricky from IBM, Ret
I share your same sentiment. I enjoy this style of troubleshooting and trouble discovery. I work in IT as well and I have found this methodology and being customer centric in both my work and communication with them having been one of the major driving forces in my career being successful.
@@davidciciora agreed. Being a software and hardware engineer I have a great respect people who do critical thinking. Using logic instead of emotions to resolve issues.
Ricky from IBM, Ret K4VMS
Always a pleasure seeing a fellow tech. be hononest and thorough. Good job Chris.
It's why I'm still here. Invariably other HVAC youtubers do that one thing I find abhorrent. I did consumer in home service on other products ages ago so I love thorough and honest.
7:06 don't look at the blades, but look at the screw where the fan assembly connects to the shaft
The key is looking outside the box and doing the job right the first time. Your T/S is on point as always.
So many people would have just pulled the bag and called it a day. There is something to be said about quality work.
I really enjoy how you can do an after-hour call and just get the very basic work done so that you can return during normal hours to do the repairs. Then you repair the damage and clean up and inspect the system to see if any other things get attention before failing again. Excellent use of time and care for the customer. Also I really like the heat-shrink crimp connectors and am moving over to them on my stuff. Great video!
You're my favorite channel. I've learned a ton from you. I appreciate you helping out all of us that are fairly new to refrigeration n light commercial ac.
I'm a HVAC technician in Australia and I love watching you work man. Much love
You can get musician's ear plugs. They help protect your hearing while keeping a good frequency response so you can still hear the issues. Some of those are noisy enough to be damaging over time, as I'm sure you know
"What?"
@@nes999 I don't know either. I am blind.
You have me looking at condensers now, checking to see if they're plugged. Haha. In our shop, there is a small office which is cooled by a large window unit. And it hasn't been cooling well for a couple of weeks. They were set on buying a new one, which is garbage, cause if i needed something for the shop it would take ages and long approvals, but if any of the office people need something they get it same day. Anyhow, pulled the unit out, took it apart and wached the condenser out, plugged full of dust and aluminum powder from the environment we are in. Put it back in and it supposedly cools better than before 😎
That klien driver is amazing I just got one a few days ago too loveeee ittt
Yep with the contactors there is also the effect on the business, a failed cooler/freezer due to a bad contactor could lead to thousands of dollars of product they then have to throw out. If its an exhaust fan for a kitchen they might have to shutdown until it fixed, again causing thousands of dollars of lost sales and the effect of not having your restaurant open may mean you get a bad reputation among customers, so it isnt just lost sales that day but more in the future.
I love it when the unit is not up in the roof. Great video. Thank you.
That plastic looks like the wrapping on product supply that trucking companies use. Nobody really cares about actually getting into the garbage. You see the plastic blowing all over the property. I deserve a raise they say. Lol.
Thanks for always doing a full job unlike most techs!!
Great Video
Top Tech
Honest Service
Godspeed Brother!
Molex perma seal branded crimp seal connectors are the best they have the adhesive inside that seals around the wire. That's all I use
I have lots of those Stanley modular sorter cases, they're awesome to organize stuff.
I agree contacter can make the biggest difference in how a machine performance i work in a grocery store and they change all the contacters once a year as a pm . Great video chris thank you and how true about kindness.
Excellent job
Hey I got that same klein tools multi bit but without the driver. I had an issue with the magnet that started to fall out. I'm glad I noticed it and just used a little superglue to keep it in. I have a lot of klein tools stuff and this is the first time I've had an issue with one of their tools. Keep up the good work.
Thank you for spending the time on cleaning up the wiring. That really scratches my itch. I work in IT and fail miserably at cable cleanup.
You'd think with the technology we have we could make a contactor that doesn't get burnt.
Thanks for the video Chris. I love the simplicity of that unit. Good eye on the cut wire and the contactor. Nice job.
Good job, thanks for the video.
I completely agree with your saying. If I appreciate I send them to clean up fans n coils before The services installer so you get throw that process.as maid service I do site visits then I get my workers there on job before me so when done I can inspect the work. Last we need someone spending 4 hrs cleaning up 1/3 of a basement
Great video, like how much information you provide for us techs out in the field without compromising key information for the DIYers 😊
Great Video.
I'm your Fan.
When in doubt, change it out. Replace worn and doubtful parts. Those are our company slogans to help reduce after hours service calls. We heavily push and train that open mind and big picture mindset.
Building up a relationship/trust with a customer takes a LONG time. Ruining it takes minutes
That's one of the advantages of these videos, the customers can see the honesty and integrity, literally from the 1st frame to the last
Being on service for the last while I noted potential problems, but it feels like most places are fix on break, The locked down has had a negative affect on most restaurants. Thanks for the vids and the walkin us through the calls its help make me a better tech.
you got to love it,condensers at floor level,thanks for sharing.
That white powder is normally referred to as corona. It's ionization of particles from electrical arcing.
I did a job where the owner had OCD and wanted everything perfect even if you could not see it. I pop up in the ceiling on to the unit, flipped a light everything was painted and well lit, I was like WTF outstanding he goes nice isn't it . Anyways someone painter left a thin plastic tarp up their and it sucked onto the coil. Then he gave me a tour and my jaw dropped, the roof had an alarm, we went up and it was spotless. If I worked for you I would order the dispatcher to direct all calls from that location to me PERIOD.
Haha, a bag in a fan? I have a story.
I once found a ceiling fan that had some sort of red Mylar streamer of sorts wound up in the center. In this case, it was on a center shaft or something and wasn’t moving with the fan. It was making a quiet s,s,s,s,s,s,s,s,s,s,s,s,s,s,s noise, and the noise went away after I pulled the plastic out. It looked like a few inches at first, but it ended up being a good 5 feet and knotted like crazy! (Fan was a basic white Hampton Bay one, probably from the 90s or so.)
It seems like these things can actually do damage to faster moving fans! I would have never thought that tiny imbalance could affect a bearing in a motor.
Love all the videos! I have learned so much from you. Quick question, Where did you get that filing cabinet for your contactors and some parts? I want to get one like that in my service van to free up some shelving space. Thanks in advance!
He's made a van tour video a while back saying where he got them

Morning Chris keep up the great work
12:40
Howdy. I ask, why not switch to solid state contactors (zero arc), with a heat sink, 1,000,000 cycles?
ty
Morning Chris !!!! Keep up the great work!!!
I personally like those supply wires to be long, (coming from the disconnect or breaker etc.. if something crazy happens and they get crispy, it leaves you enough slack to just cut it back and not have to pull new wire or have to call an electrician
👌good Staff Chris
Your 100% correct the $100-200 contractor is cheap on the follow up call / PM. It’s much more expensive for that callback a month later on overtime when the whole system has tanked, that could have been prevented.
Your environment also takes a toll on the contractors between sand, ash, smog. They all lead to premature wear on the system.
On that particular location I thought there was talk of putting a galvanized cover over the line sets to conceal them from the scrappers.
Nice. You even use the same lighter as me
Great point about 3 phase. But now I pose this question. Why not take that same concern with a phase monitor? Why not protect the equipment from high or low voltage? Either of those may have been the "Big Picture" to have caused that contactor to do that. More so low voltage.. but you get my point. You can have the monitor reset.. but store the faults and when back know 110% in issue or not. Stay safe and be well Chris.
I LOVE heat-shrink butt connectors. They are excellent for electrical repairs on cars and garden tractors, just as robust as their standard counterparts while adding weather resistance (and a tiny bit of mechanical support for the connection itself). Combine those with adhesive-lined heat shrink tubing, and you can make a connection that lasts for years.
It's always a good idea to check contactors. Contactors are used in high-current applications, and closing/opening high-current circuits creates an arc nearly every time. Burning/pitting of the contact points is just the nature of the beast, and as you mentioned in your closing remarks, single-phasing a compressor will cost the customer exponentially more than changing out a contactor. It's not just a new compressor, it's potential loss of product/business too. Spend a penny to save a pound.
Changing the fan motor should probably include automatic contactor and capacitor replacement because they all work together, and a failure in one component can sometimes cause cascading failures of the other components. Why bother with a new fan motor if you're going to feed it poor power through a bad contactor, or a cap that could be teetering on the edge of tolerance?
💪👍🇺🇸❄🙏 much appreciate u sharing ur knowledge n experience. B safe 💪 🙏🙏
I remember that video. Damn tweakers!
The wiring is night and Day difference!
Looks like Wurth brand @ 5:15
Hi y’all from west Alabama
Man I feel bad for those guys. The 2 tweaker videos then what's the chances of plastic making it all the way into the unit? Wow
Great video, notice the old book on the desk, would that be HVACR bible.
Have a great Sunday!
One day you WILL drop that container of splices... I have the same Stanley containers and dropped my splices twice so far. You will live with them mixed up for about a week until you get ticked off enough to sort them again. I walk with one finger over the lid just in case the latches give way, but eventually it will drop.
I carry mine the same.... one of my guys dropped my screw case one day and it was a nightmare.....
Am I right to be concerned that there's no start delay on the compressor after power is restored? And that the condenser fan runs continuously?
Australian here. (Not qualified, just watch because this stuff is interesting)
It pays to use your senses when working on the unit to spot anything that might cause more downtime for the customer.
That reflects well on your customer's experience, as they know you did a thorough job and found some issues that could have caused more downtime in the future.
Do you pack heat when going to a neighborhood like that at night?
Hi..from Kenya
You can see the out of balance with the set screw on the fan blade at around 1:50
Where’s you get the Kline multi driver ???
I got a question, why do these systems have a king valve on the discharge of the compressor if I am looking right?
The white powder, is ozone. From the arcing
Damn I miss being a tech well yes and no idk man lot of love for hvac but I’m pursuing different route
QUESTION REGARDING CONTACTOR: The unit under repair looked like a fairly new unit. Might there be something else going on that is short-cycling the contactor resulting in a shortened life?
Goodmoring
Im sure changing a contactor is far cheaper than having you come out
Called to a job at a hotel were I look after all the package ac unit the other day, they have a different company that look after there fridges, they asked me can I look at one of there walk in, I said sure apparently the other company has been out twice replaced the pressure switch the 1st time then told the customer the 2nd time the condenser unit needs replacing, I walked into the cool room a balloon was stuck in the coil, coil frozen up hitting the fan, defrost and replaced the fan and now running well, don’t know if the other company was looking at the wrong walk in or what haha
Why did you stick your hand in that fan impellor at 3.00 minutes .the supply hadnt been disconnected to it . Theoretically could have kicked back in and taken yout fingers
When you find burnt stuff like the contractor is that just thrown in or do you request more money?
damn tweekers!
Would you rather be called out for an emergency call where everything was ruined and broken OR be called out for an emergency call like this where it's an easy step to running again?
Contactors are of such poor quality these days, we get pretty steady 240v here and contacts look like they are starting to weld themselves after year 2, and I see contactors that are 20 y/o with years of service left in them.
If someone says that you change too many contactors, I would be worried about that technician doing disservices instead of helping my customers out.
Not many techs will ever be this. Most techs I’ve ever seen would’ve just pulled the bag out, possibly changed the motor if it was too loud. But they would’ve left it if it wasn’t too loud.
You should be working for NASA with your carefulness.
Always change the contactor. Its a low price insurance policy.
Do you have a part number on your sliding drawer you have your contractors in? Thanks.
Found it. Crescent jo-box.
Do you have a name or a link to that drawer system in your van ?
Let me know when your multi bit Klein tool breaks.
Damn that wire organization is sexy
Maybe they threw the plastic bag in there to quiet down the noisy motor! ;)
Seriously - You walk up to a machine, turn it on, and the 1st thing out of your mouth: "Sounds like a plastic bag..." . You kinda supermanned that thing!
👍
Can we get some Make up Air videos??
Contactors are cheep compared to the price of a motor or compressor....
How can I work for you?
Someone should invent a smart contractor that has circuitry to detect these failures that can harm downstream equipment and take itself out of service automagically. It would easy to do it with 50 to 60 dollars in parts. Double the price of the contractor. Never blow another compressor. It would end be to difficult as we already have the tech. Just some multimeter parts and an circuit breaker
Tomorrow is my birthday
I'm an electrician from Germany, i always wonder, why you guys in america don't build in 3 phase check relais... they're 10 bucks but can save a motor from 2phasing.
Or at least a motor starter with motor protection-relais. Last videos there was one shorted compressor out of 3, that blew the main breaker and the entire unit was down... this may not happen.
There were only contactors, no protection switches... very poor build quality in my eyes... and when an apprentice does such wiring harnesses like in those units like spider webs... man, he'd get fired the same day!
It almost looks like someone sneaked in there and vandalized the unit with that plastic bag, because I don't see how it could get in there by itself. The fan pushes out air through the grill, and there's no way that the bag could get through the coil by itself like that. Someone sneaked in, waited for the moment when the fan stopped, then that individual pushed in that bag with a stick or something. Stupid humans can break things in the most ingenious ways. That, or *just perhaps* , the fan ran backward occasionally. So probably it'd have been a good idea to check the runcap of the fan, because that may have been the actual culprit.
That’s what I was thinkn…with all the grates and fan blowing opposite the direction…no way that bag “made”‘it’s own way in 🤔🤨. Highly suspect
🤘🤘🤘🤘🤘🤘🤘
You a beast but upgrade to a fluke meter 🔥
819 thumbs up
HI CHRIS! WHY DO THESE UNITS NOT USE SOLID STATE CONTRACTORS? THAT WOULD SOLVE THE ISSUES YOU SEE WITH THE POINTS NO?
The main problem is efficiency.
SSRs and sold state contactors have a voltage drop across them.
At high currents this can present a rather substantial power loss.
Compounded over how long these units run, and how many units they have, this can represent a significant energy loss - and cost.
Coupling with how aggressive manufacturers and governments alike are getting in pursuing every last watthour of efficiency, I'm honestly not surprised they aren't really used.
An exception would be in a lower power situation where rapid cycle times are needed, such as an unload solenoid for higher setpoint accuracy.
Unloading systems can cycle as rapidly as once every few seconds, which would present a rather severe problem for contact erosion. A solid state solution would be ideal here.
@@FerralVideo this makes total sense great response!
a 40 amp 3 phase contactor is $30, a 40 amp SSR will run you $200 the reasons are clear.
@@FerralVideo 👍 Voltage drop = heat. Heat in a place that is already hot is a bigger task to deal with, so it is now not just a SSR
