I love watching someone that deeply understands their trade and does the right thing for the customer. Thanks and keep them coming!

0:58 - If I could get that much water pressure/flow from the hot water tap at work, and _actually_ have hot water, I'd consider myself blessed.

Looking at the big picture when diagnosing a problem is the only way to do it in my opinion. I’ll be doing things the same way that you do when I’m a technician Chris. Thank you for the awesome video! 👍🏻
Hey man little tip for brazing when you have pieces that won't stay still and keep trying to twist pinch the fitting with the copper in it already and just oval it a little with your channel locks, keeps things exactly where you want them.
Be careful. Viper had a bad batch of wet rag with a caustic pH get out. I can tell you from personal experience that it will eat through tubing. Now I use actual wet rags and the cool gel spray.
I have worked on service calls involving units having dirty condenser coils. Sometimes the units are just undersized. I can't tell from distance over the internet when connected to a customer's BMS.
Great video as always brother! I got a new hat last week and I love seeing people recognizing your channel out in the field and at supply houses! Take care everyone!
I work in Software development and the youtube Agorithm sent your videos my way, I have no clue about HVACR but I worked at an employer which would credit any training over 500$ to me and I had to pay it over by staying for 36 month for the company, in turn nobody took any trainings.

Over years of scrapping and recovering large commercial refrigerator systems I always found it worked better to use the dip tube because when the large tanks got halfway full it would force the hot gas coming from the recovery compressor through the colder already condensed liquid. Going in from the top the whole tank gets hot quickly and the pressure goes through the roof when you stop pulling liquid through the heat exchanger in the recovery machine.
That coil was pretty bad. I finally got the RT foam gun and love it. I had a filter drier on a 2 stage carrier unit that caused the compressor to go bad. It had a 40⁰ drop across the filter. Great video Chris I love that you keep doing good work even though you have been beat down. Thanks for another great video.
I have been fired because I asked for help. One company told me that I was not aloud to talk to teck support when i need help. Sounds like you are a good business, keep it up.
Looking at the big picture is time consuming but it definitely saves you plenty of call backs. And also another classic example of always get superheat and sub cooling. Most technicians would have ran straight to the van for a bottle of refrigerant for that first circuit.
great vid as always, you are the kind of "boss" i'd want to work for, but 2 things keep me from that. 1) i dont work on ac stuffs 2)i refuse to live in comunistfornia! although im a lot closer than i used to be, was in central Fl, now in west arizona!
Chris my local codes on east coast allows us to run condensate on roof currently. Is it code to have condensate piped to a inside drain from RTU's where you live ?
One thing a lot of people forget is that part of having a career in a certain area is constantly learning and maintaining that skillset so your skillset remains relevant and useful - including & especially as a supervisory person. On top of a skillset is the work ethic. You can be the most talented person in your field, but if you don't care about your work, what even is the point? Big picture ftw.
As far as the rope goes, there's been some studies that do clearly show that dirty ropes wear out faster. Keeping it out of the dirt is a good habit to have.
One thing I’ve always wondered is why do the units not come with screens on the condensers? I feel like having a screen would make it easier to clean and maintain the equipment, since the screen would capture most of the dirt instead of the condenser.
It's like car mechanics and machinist/engine rebuilders. You have parts swappers and people who understand the whole system. Usually the initial reason something isn't working right or a part failure. Is because of something else is out of whack that contributed to that part failing.
Reactive maintenance......is never a great idea....i understand it....but its still a bad decision....it costs more in the long run. Oh well. Pay me now.....and pay me later $$$$$$$$$....great video Chris😮
Thinking big picture are a required traits for technician in all fields. root cause analysis on every single problems helps in the long run. I been watching your channel for a year now. And now I know a bit and some about AC and how to take care of them. Not just calling AC technician to just clean it (and often doing a half ass job and I don't notice about it before). I have a questions, from time to time, I see your shelf on your right in the office behind are on a constant shuffle. sometimes it tall, sometimes it short. Why? 😁
This might be a dumb question, but would it be a good idea to flush the remains of the old oil using some liquid (like alcohol) using a circulation pump and whatnot when you have to switch oil type? Or would that just cause lots of other problems?
I like to heat up the pipe a few inches from the new drier and let the heat follow the pipe into the new joint then move quickly to the joint and flow in the silphos, ( just my approach) seems to work Weill Jimbo..
Training is a must. But it can't all be done at the shop. I will never work for a company that does not send employees to schools. That being said, it depends on the type of company. Regular residential ok I don't expect that type of company to send me to schools. But I do expect to go to classes about new controls ect. If no one knows how the new stuff coming out works then no one knows. You don't know what you don't know. But it is up to the employee just as much to educate themselves. Download PDFs, look up anything you can. Use tech help. Lots of times they will give u bits of info you didn't even call for. It's your trade. Do what ever you can to become the best you can. Sometimes it is up to us to learn without pay. The payment is the education you get . Small classes that the supply houses put on ect. It's a great trade with so many angles. There are so many great people in this trade to learn from. And of course this platform. I have learned alot. Ways to do things. Iv changed some things iv done . Iv found new tools by wathing hvac youtube channels .
The condenser cabinet had to be opened, si instead of the fans drawing air through the coils, it takes the short easy way through the large opening where the side panel was removed, which would then allow the head pressure to build to a point of tripping a safety, along with not allowing the refrigerant to give up its heat and condense back into a liquid.
Hey Chris, I have a question, i have a scottsman ice machine i picked up from auction. Unfortunately the evaporator plate was falling apart (didn't know that it was) bought a replacement and I'm going to tackle replacement soon. Main question is, can i use argon to back purge the system as i sweat the lines? We use argon to purge stainless steel so it doesn't sugar. I just have access to argon but not nitrogen. And what silver solder should i use? I have experience in mig tig welding and electrical soldering. But never actually brazed. So I'm pretty excited to take this on.
yes straight argon will work fine(great) but it's a "noble gas" and costs fairly more than nitrogen. if you have standard sized empty argon cylinders, welding gas suppliers may let you swap them for same size nitrogen tank's for only the cost of the gas.(they're both CGA580 valve connections, as well as other welding shield gas blends) assuming the tanks are in good shape (expired certification date or not).
Hello Chris, good afternoon. here in Las Vegas it's 2:30pm. I'm just watching your video. I've been following you on UA-cam for 5 years and I'm subscribed to your channel. You are the best air conditioning and Refrigeration technician in the last 5 years. But I wanted to make an observation without disturbing you, it is very important that when you start making an air conditioning or Refrigeration video that you first show the Model and type of the unit to know what equipment we are talking about and how many tons of Refrigeration it is. Also, what type of Refrigerant are you working with and if the Refrigerant was replaced. because I am looking at very low suction pressure and very low high pressure. but you did not clarify what type of refrigerant we are working with. nor how many tons the air conditioning equipment is. I do know because I have been working in air conditioning and Refrigeration for 40 years and my Father was an air conditioning and Refrigeration technician in Córdoba Argentina. But I have been living and working in HVAC & Refrigeration in the USA for 26 years. It is because you have many technicians and followers who have just graduated from HVAC and are not going to understand what you are explaining. Thank you very much in advance.

A nitrogen tank is fairly cheap.. same place you get your welding supplies
Argon is generally less reactive than nitrogen, my theory is they use nitrogen because its cheaper than argon. I could be wrong though
Argon will work equally well as nitrogen. If you already have it go with it.
Argon is better than nitrogen but it’s too expensive so not used commonly. Safe to use.
yes straight argon will work fine(great) but it's a "noble gas" and costs fairly more than nitrogen. if you have standard sized empty argon cylinders, welding gas suppliers may let you swap them for same size nitrogen tank's for only the cost of the gas.(they're both CGA580 valve connections, as well as other welding shield gas blends)
