You say big picture, I say thorough. Yes, it makes you more money but also allows you to inform the customer of all the problems they need to know. It is always up to the customer whether they want to fix it or band-aid it. A good tech like Chris finds all of the problems that a business needs to know in order to keep their equipment operating which keeps the business running. Well done, sir. I wonder if people who don't understand regular maintenance get their car's oil changed or do they drive it till its screwed.
You reminded me LongLife oil bubble in Europe. It was a laugh. Very costly for car owners laugh. Advertised as X2-X3 mileage (for sake X10-X20 cost). But they did forget to tell the oil itself that is have to last longer. So the oil did not...
It's a good channel to watch. Troubleshooting skills can be adapted for anything. That and there's gonna be no end to people wanting HVAC / having to fix and install it.
The video you mentioned was literally the very first video I saw on your channel. The moment you showed the condensing unit my brain went ‚He changed the compressor on that unit.‘ before you even mentioned it. 😂 Keep up the great work. Greetings from Germany.
Well said Chris you are not worth stealing time from your company, I rather give time than steal it from a company. Good video on what to look and hear things as you work to keep the company invested in you. For sure.
You wanna see some mud come out of a coil do a PM on a BBQ joints roof, we also had a walk in evap we called "tuna coil" cause they store all their raw fish right where it intakes, washing that coil isnt for the faint of heart haha i worked 1.5 yrs as a PM tech in KC for mostly restaurants, taught me A LOT.
A TXV is mainly to protect the compressor from liquid slugging. I myself always tried to keep the evaporators as flooded as possible due to limited power available in Alaskan villages.
I super agree about the idea of becoming a valuable employee. Finding work and building good, reliable relationships with customers is very important! Much more than stealing a few hours a week. That’s a hard lesson to learn and a hard lesson to teach! At least in my opinion. Great video as always!
I’ve been 3 years in the business and this year I barely started working on refrigeration units. The way you explain everything is so helpful and understandable. I always follow your procedures, thanks to my friend that recommended me your channel he used to work for you. Now he’s here in Austin Texas 🤘🏼
I wonder how long an old-style sealed motor would last compared to the newer open style. I realize the new ones are "More efficient", but they are also somewhat budget built to meet the minimum. I'm sure an old-style motor which used more wire and material would also run cooler and last longer, as well as protect the insides from all the sand.
Race to the bottom. Manufactures don't need to care about big picture / long term esp not anymore. Just make it cheaper than the next place bc if not just gonna get skipped over.
I left my company because of too many people in my company trying to "milk the clock". I was paid very well too. I got tired of the laziness. I started my own company and im glad with my decision. Im busy and successful so far.
That's saying a lot about someone who doesn't like to invest in their equipment if they don't like to dump a lot of money into it and just love getting by which is totally fine for me for refrigerator or Heating and Cooling or whatever I'm going straight for heat pump like a Mitsubishi electric hyper heat pump
No doubt you know what you are doing. Love the pleated filters in the MUA unit. Changed the wrong RTU unit? How does that happen .. oh let me guess.....the lowest bidder I bet. I used to use a checklist to check everything on every service call to cover my butt. Most techs do not do this.....and they should check everything. Also...it is wise to carry two 9721 fan motors in truck stock for the very reason you pointed out. Change both motors not just one motor. Great job! Your customers are blessed to have a technician like you. I hope they know what they got!
Thanks Tim for the nice words, also please don't guess restaurant names in the comments , right or wrong if there is aa restaurant name those always get deleted because I have to protect my customers as some people are just plain jerks and want to cause problems with restaurants.
Good stuff Chris....being thorough always pays off. It can help the customer and the tech. Whether they want to pay for all of it....isn't my decision and won't affect me in any sort of way. I like to check out as much as i can, within reason...i find most are happy with being detailed and will approve the whole boat.
Wish u could teach me if I could be one of your helpers , been out of school now since 2014 and still haven't found work, that's why I'm studying you're videos so I can land a job
I found that particular company to be good to work with. It is interesting that they keep the chicken wings at that temp but they do go through it quickly at that. Don't get me started on Supper Bowl weekends. I also ran into the same issues with the sensors being placed there and the loaders/kids putting boxes over the sensors or even worst ripping it right out of the door control. When ever I was given the parts to replace the control with the long cable, I would run the sensor to the back of the coil to get it sensing better and explained it to the managers on that.
Chris, I noticed on the outro that you seemed very flat. I hope you're doing OK and looking after yourself. Thanks for another fantastic and informative video. Cheers from Adelaide, South Australia.
Muchas felicidades mi estimado Chris debió ser una gran experiencia tu visita en ese lugar. Y como siempre un gran trabajo el tuyo. Saludos y abrazos desde Coacalco estado de México.

I've found that the proper tension is to leave a little plastic hanging to the zip ties as cutting them flush weakens the plastic too much in the area of the plastic ratchet.
Funny sometimes malfunctioning equipment can "seem" to be working well, cool ambient but missing half the condenser fan balances out for now.... but wait until ambient is normal to hot!
If they put boxes there, might be an idea to put a small bracket around the top of the temp probe and by the wire, to force a bit of clearance. Might help.
Another way of saying what you are pointing out is to 'take a little pride in your work'. It is obvious that you really take pride in your work. In my opinion, that makes you a true craftsman and I say that about not many people.
I also struggled with this my first year, now in my second year doing much better talking to customers, once you become confident in your knowledge itll flow. Its not a matter of getting a customer or manager to see stuff needs fixed, its getting them to see youre the man for the job.
dang that sucks well can't get em all I guess, also I am a junior in high school and going to trade school have any recommendations? Because I also want to do HVAC@@HVACRVIDEOS
Thank you for cutting the zip-tie tails. Even if it decapitates someone, at least you made it look like a professional did the work. Not saying you aren't a pro if course. Just a huge peeve of mine when people leave tails on. And flush cuts are tiny, take up a little room... just sayin' ;)
Is the ground on the motors really necessary? The motor is bolted to the metal housing which is mounted to the whole cabinet which is mounted. I’ve always been told that ground isn’t 100% necessary.
Can you guarantee a path to earth through all those connections without an earth cable then or after you leave? . irrespective of if you think the earth path via mounting bolts to the panels is ok.The real answer is no. Hence an earth cable to a suitable point should always be used. Big picture stuff.
The sensor should have a cage around it for protection and to stop boxes stacked too close to leave a gap but either way in this case it's just in the wrong position.
Nothing lasts on this equip, but the 9721 motors last the longest, I never use them on evaps because they are way too big and have way to many wires. Even the OEM heatcraft motors don't last in the harsh desert heat, 12-18 months is all you get in those environments
You should have replaced those evap plastic undersized fans. They don't even move half as much air as the Heatcraft fans. All you get is quicker coil frost, lower suction , higher Evap TD, higher compression ratio, shorter compressor run times, uneven room/product temp, and doesn't help with oil return either. Someone lied to that customer that they would be saving money with those "High efficiency fans".
Yep the entire company got sold a box of rocks with those stupid "energy efficient" motors... we are not supposed to change them unless they fail and you are right they just dont move enough air
-3F SST on a 28 degree room temp ?! That system is not running properly, it all goes back to the undersized Evaporator fans. Not a properly run service call. Wrong condenser motors and wrong evaporator fan blades, which means more issues down the line.
You are right nothing is running right, but for lots of reasons, the condenser fan motors are moving the right amount of air, the evaps are not and the compressor is a fixed speed comp sized to 120 degrees outdoor ambient conditions so now that it is 45-55 degrees outside the compressor becomes a monster fixed speed comp with no real capacity control... We run into td issues because of it for sure. A digital scroll would be a great choice but the customer wont invest that money into this place.
if you change the evap fans the SST will jump by 10-15 degrees< and then you might find out that you have to open up the txv. This is what I see almost every week in my neck of the woods on 3 major national chains
