The apprentice did a really good job brazing 👍👍
He is doing a great job! I don't think it's fair to call him an apprentice anymore he has his own on call and rarely needs my help!
I have to say I am thankful that these videos came out of nowhere for me. After about a month or so of watching through these videos nonstop, I now have a big desire to work as a HVAC-R technician and also learned how I can be a better person.
Thank you Chris for allowing these videos to be public even if they were originally meant for your employees. You've inspired me greatly haha
He also has made me feel as if I would like. To be a HVAC-R tech
I'm so glad that I'm getting out of resi retro and into doing commercial HVAC and refrigeration. These videos have been very helpful in giving me a bit of an education so that I don't go into my new job fully blind.
Agreed, Chris’ videos are an awesome way to learn and improve!
OMG! Residential and retrofit...definitely bad words, especially when they are in the same sentence. lol. IMO you are going to be a much happier tech now.
@@oldmetalguy4577 moving from being an install helper who knew how to do it all from removal to startup n commissioning a system to fixing broken stuff.
He makes great videos but this is light commercial, if you wanna learn actual commercial refrigeration watch other UA-camrs like refrigeration confidential and refrigeration tech👍🏻
I'm pretty sure I remember the video where you changed that receiver. I'm surprised it failed so soon, that's a bit ridiculous in my opinion.
I got 3 of the same recovery tanks from Grainger over the past couple months and 2/3 were flat with no issues pumping down, but 1 was pressurized and full of moisture as well.
Been doing HVAC/R for 16 years and counting. I've watched every video for the past few years. Always informative and I get a good laugh when you run into a problem I've run into before.
The Fieldpiece recovery machine does have an inlet screen. Mine came with a couple spares zip-tied to the inlet when it was new.
Very convenient for that oil dump valve
Fifty bucks says the recovery tank has one or two valve stem leaks.
The moisture you were trapping in the oil was from atmospheric air. Smear the tank's valve stems with Low Vapor Pressure Grease, Dow-Corning High Vacuum Grease, or a heavy & thick silicone grease to block wet air being drawn in. If you still have the problem tank, cap the ports, paint the valve stems with bubble leak detect, then open the valves - bet you there will be a stem leak under pressure as well.
Well spend 2 hrs a day to watch your content. Thank you👍👍👍💪💪💪
The apprentice doesn’t rate a solding jam just yet, but they did a good job. 😂 Keep up the great work!
I’m a service manager where I work and I send my guys these videos! Great stuff man! I appreciate what you do and I can relate to all of it. We also do a lot of restaurants and that is an interesting aspect to HVAC/R. Not to mention funeral homes, we do a lot of the refrigeration for funeral homes where I live, and to be sure, we work around dead bodies in a cooler. Love this trade and love this channel! Keep up the great work!
Automotive touch up paint is amazing for little spots with high quality paint, most have a nail polish style brush inside
WOW, Chris. The 1st time I've ever heard you said "silver solder" Which is finally correct the term
. Have you ever actually done "brazing" with an actual brass brazing rod.
I m starting to like that recovery setup. Thanks
I was just going to joke that he used a voice double at the worksites (because we typically wouldn't see him on camera). There goes that one, I guess 😜
Thanks for doing what you do and sharing some of it with the rest of us!
Nice job, as usual, it's funny what you catch when editing even when you don't notice real time.
Here we get recovery cylinders which are for filling with refrigerant to be sent back for recycling or destruction which will likely be dirty cylinders, and receiver cylinders which are supplied clean and are designed to hold refrigerant while a repair is made and then sent back empty.
The POV coaching while brazing was a good vid spot.
I would’ve forgotten the backup vacuum pump oil.
I usually just put in a female flare fitting filter drier as well depending on the situation no point putting it if it’s only you working on the unit good video Chris 👍
Have you tried the Harris blue stick or orange stick? Way easier. Dont need flux. The flux us already on the rod. Blue is 45 orange is 56
Another solid video Chris, I appreciate your work.
I’m curious your thoughts. Since the system had a leak with a zeotropic refrigerant in R404A, the existing refrigerant could have been deemed as fractionated and not reusable?
Thank U for this video, love your confidence
Good to see you have st least one extra pair of hands for jobs like this.
yes chris it helps if you open the valve rookie mistake been there done that
Easy to make mistakes - especially when you're distracted by trying to film at the same time.
@@russellhltn1396 true
19:45 it’s on the inlet side of the recovery unit. If you open twist the knob it’s inside the fitting.
Wet rag wrapped around valve, or cooling it immediately after brazing is recommended. As well as angling the flame away from valve more. Still looked like a great repair though, and brazing was done quickly enough it shouldn't have damaged the internal packing nut gasket. Crazy to have that much moisture in a recovery tank!
He does that a lot. I'm not sure why not here.
I get my recovery tanks through rsd and this has happened to me one time on a 125 pound tank. Usually if I have to evacuate a small tank I don't need an oil change
Those recovery tanks probably are coming from hussmann… I do rack refrigeration and all new hussmann equipment we’ve installed in the past 6 months has been pressurized with COMPRESSED AIR instead of nitrogen. Takes at least 24 hours to pull a good vacuum on anything new and dehydrate the system. Absolute madness. Not sure why they do it But whatever reason they do the recovery cylinder manufacturer is probably following suit…
Did that recovery tank come from Florida?
good question i have never seen on have that much mosture in it
Politeness is a given, respect is earned. When I'm polite to start, and the other party is rude, that means that I won't even try to have respect for them, and I no longer need to disguise my feelings with politeness. It doesn't necessarily mean epithets, but blunt speaking becomes the norm.
An intelligent person learns from his mistakes,a wise person learns from other peoples mistakes.
U really know your stuff but i wonder why you change your oil so often on your pump
I've heard that when nitrogen tanks when are not depleted fully before charging something else with it it will cause it to sometimes condense moisture inside happens at manufacturing
You are right....we all make mistakes....its part of life and can't be avoided...its what makes us perfectly imperfect
Good video. One question though. Why do you not use a nitrogen purge when brazing? Just curiosity, not criticism.
often does
Without burning me 🤣
Where is the condenser fan??
Charging old gas through a fresh drier is a good thing to do. Extra cost I know but beneficial
Great job Chris
You always talk about keeping your ears open when on the roof and not wear headphones, but I noticed you seem to be using those Aftershokz bone conduction headset with the boom mic. What's your opinion on those? Does it being open ear mean you can hear equipment noises clearly enough?
Yeah they are great and really do a good job of letting you still hear everything around you, but they are a bit difficult to hear the phone call when its really noisy around you.....
Why do you cool with oxygen instead of the hydrocarbon gas? It seems like a reducing atmosphere would be better...
There's a strainer that can be changed on the fieldpiece and appion.
“That’s plenty of silver solder!!”
You sound like the guy who pays the bills. That stuff ain’t cheap.
What about the compressor frosting up next to that one?
I believe what you are looking at is the DTC valve or discharge temperature control valve also known as liquid injection valve. Meant to keep compressor head cool and can/is supposed to frost up like that.
Chris I have a question!What do you think if companies starting making refrigeration units that have a variable speed compressor just like some new mini split air conditioners!like based on the temps the compressor would speed up or slow down!By your opinion do you think it could be a good idea to go with this tech and would it be a good way for power savings?
Answer it when you have the time and I hope you understand what I meant with the mini split part!
Thank you
Hello, that's basically the standard in Germany on Japan made refrigeration, any size and every component (like the compressor / condenser Fan) gets controlled via a inverter board.
America is still quite away from that technology but it will come eventually.
@@pascalleben6077 this technology does exist here in America, but it adds significantly to the cost of the unit. I had to replace my air conditioner in my house this summer, and the unit with variable speed compressor was about $10,000 more than a new unit with fixed speed compressor and condenser fan. At that rate it would take over 20 years to pay for the extra cost in energy savings, and the unit probably wouldn't last that long. I imagine that there is a similar price difference in commercial refrigeration units for variable speed, at least to some point where there is a better cost justification for variable speed.
@@rnreajr9184 Agreed. Unless mandated by law, this technology will become the standard only when production costs become low enough or the demand is high enough. Until then, the least expensive production method will be mainstream.
Hey Chris what office chair is that?
Wet rag valve?
At how many lbs did it clear ?
Everybody makes mistakes no harm done
o no she done sprung a leak LOL
Keep your flame away from the vale
Hello i am the first one here and i enjoy your videos
Here first love the videos
I was here first
No you're not xbox came first
91 Thumbs uP
Go kansas city chiefs
GO BILLS
You're doing it wrong.
The reason why your making mistakes is your mind is not focused on what your doing, your focused on making a video I wonder what your customers would think if they knew
While your focus on watching him make a very simple mistake. Fucking stooge
Disgruntled?
They would probably be happy that a person who is so familiar with refrigeration circuits and controls that had the ability to teach and make a video is working on their system. Top notch technicians are hard to find, if I had one working on my system that was comfortable with doing repairs and making a video, I’d be stoked!
@4:56 "we cant put it into a vacuum because we are going to be reusing the refrigerant" what do you mean? like there's no point?
not a tech just wanna learn
