Amateur Install... Your brazing sucks
Hahaha, thanks for watching
What was wrong with it then?
always someone who thinks they are better
it's actually bad
what is wrong with it ?
Two things I learned form reading the comments section:
1. You did an excellent job, used all the correct materials and techniques, will last for many years, won't leak even during an earthquake
2. You did everything wrong, it will last about a week and by then you will have changed phone number and business name
-Thanks, RUclips, so helpful!
Is he supposed to put nitrogen purge on liquid line when doing suction? Or both the same. Cause he will burnt that hose gasket every time.
The lesson here is….don’t learn from comments on RUclips, tard.
He should have done...
Then there's real life. He's done this job a million times and can do it in his sleep.He's been working straight for the last 100 days 12-14 hours a day. The homeowner has been waiting for him for two weeks without AC, he's tired, It's hotter than a pizza oven, he's got 3 more customers on the phone that need him "right away" and his wife wants him to stop by the store on his way home to grab a half gallon of milk.
He's almost out of gas and he's into the odorant which is why his flame is orange so he's busting his butt to get the job done ASAP before he runs out of gas.
The joints hold pressure and vacuum. He's good to go and the customer is happy.
There you go. Real life.
@Nofirst Nolast i guess he probably sanded them a deburred before brazing but didnt show it in the video? I hope haha
@@johnrael3128 who the hell sands brand new copper?
Right on man
@Billy Mack, Texas Detective Sanding won't hurt though
Whether to sand (or abrade) or not depends on several things. It's always a good idea though on either brazing or soldering ... if you have time and the tubes aren't known to be contaminant free. And he used a flux rod made for brazing copper to copper; It contains and uses phosphorus as the flux agent. Soldering & brazing aren't kissing cousins; They're brother and sister. Only one is younger (requires a slightly lower temp .... soldering). Deburring would've been good; At minimum, it would keep particulates out of the system. However, compared to the size of the system, that's negligible. Still, better safe than sorry. Hope the tubes are clean. Or else he'll get pinhole leaks (at minimum). Now, or a few years from now.
Your brazing is so clean. I just started my HVAC schooling 3 months ago. We just started our brazing and I'm gonna emulate this! Awesome work.
maybe put a little more because i did like that one time and was told to make it thicker
Bro can I get your HVAC study material,.I mean notebook and all
I started HVAC school in my town of El Paso TX, I truly appreciate every post you guys make, it helps me in the lab every time, thanks for posting
Puro chuco town
Less 90s the better I would of just bent 45s on that pipe
He protects the services valve
He purges the joint
He changes the tip
He heats the tube not filter metal
The distance of the flame was good
But the best thing of this job, was the speed of how this job was done, this guy did not spend too much time and it was a clean job
These were the characteristics of a professional job
I like the space between the unit and the house. In my area they are tight to the house and sometimes in a corner so you can't service half of the coil and good luck if a capacitor goes.
@@cptrazerblades yea us too we we live we had a hurricane sandy so now all jobs by the beaches all condensers half to be on like a 5 foot platform
You didn't address the black soot and the blue overheating of the copper. That black soot is now into the metal as well as all that O2 (oxidation). That copper is now annealed. Ask any welder what they would use on a soft copper braze.
He never cleaned the joint. The odds of proper capillary action are far less due to that.
@@jimdavidson5208 That soot happens on the pipe due to oxygen. It's fine as long as you purge nitrogen through the pipe. This job wasn't overheated.
You look on top of your game bruh...game face and everything...that is what working for yourself does. Nice work as per usual.
I'm never too old to learn. Thanks!
I do not lose any video of you, I'm from Brazil and I consider you one of the best technician in the United States.
I love Bosch units, so easy and simple to wire and so quiet.
Bosch is just a reseller. That pay extra to slap their logo on it.
I'm still worried about longevity on Bosch inverters. Working on their Re-branded Carrier WSHPs leaves sensor dependability wanting.
I love that pvc move. I never thought of running line set through it. Thank you.
Those braze joints are 🔥. Clean work, and no tape on the armaflex insulation. You might be one of those installers that service techs dont dread going behind. Great work
Here come all the hvac experts on here that probably can’t even hammer in a nail if their life depended on it. Keep up the good work.
SO true
Love the new line set insulation, makes it easier to run and and does not get cut like the black one. Greta install Stephen 🥇
The person that invented that crappy black insulation should be pulled through the wall instead of his lineset
3 years later and nobody uses this lineset anymore. The black sucks, but the white was shittier tube.
@@jdackeretdackeret4039 In my area we still use the white one for the most part.
Love the work (spot ON) most tech have NO clue / core pull / nitrogen purge sweet. I normally touch cold to see when I got my melt...………..
I'm learning hvac and I cant wait to get more hands on experience with this I done brazing pipes toghether, cut duct board and made plenum out of it and now we are going to work with sheet metal
Need a machine for A/C tube bending process? May contact by bestgift6@aliyun.com +8613202919508(whatsapp)
thanks
loll ductboard

BRAVO! i have been in the trades 20 plus years an this is the real deal clean an perfect braze. nothing wrong with leaning on the joints but not at all necessary.
Gosh man, that is some of the cleanest brazing joints I’ve ever seen especially with a oxy/acty rig. Most of the guys I’ve seen get it too hot. Love the camera angle better too rather than first person you get a better feel of what’s going on. Keep up the good work Stephen!
Just a tip on the torch setup. Leave a small feather above the cone. This ensures you don't have an oxidizing flame that causes pinholes. My torch tends to light rich and drift lean with use due to the regulator. Keeping a feather assures me it didn't go to excess oxygen. It also helps to flux the copper in the oxygen free feather. Surprised you didn't reinstall the insulation on the suction line and compress it away from the joint for brazing. Saves having to split and glue afterward.
OA is overkill in my opinion. I just use acetylene. Most people will burn the complete shit out of something using oa
Thanks for showing the whole brazing process. Most RUclipsrs don’t.
Thanks for watching
Awesome quality! You can tell how much you care about it your workmanship!
I see negative comments here. But as a guy in this business for over 25 years, your work looks great!!
100% agree with most of the comments. I bend, braze and cut copper all day making Evap coils. It takes time but reaming your cut ends and using an abrasive cloth to clean them makes a world of difference. Also always use nitro for keeping oxidation down! I've put out hundreds of evap coils and havent had a single leak or restriction problem! Knock on wood lol. I am confident in my process if you are too lazy to use a hand reamer you can always buy a Wood Countersink or even a Unibit ive found to work really well to debur with a drill.
Do have any steps or sequence in your process. Or tip or techniques
Thanks for posting, I've used the wet rag technique but never thought of running nitrogen as an extra cooling agent in the input as some of the comments say. Thanks for posting I know it takes work and I appreciate the effort
The nitrogen is to prevent oxidation and the formation of scale inside the pipe. R-410 A and POE will scrub it off the pipe and clog the metering device. Cooling effect is minimal. It's the water keeping the pipe a 212 Degrees that prevents damage to the valve. The torch flame is about 2200 and the brazing rod melts at about 850.
@@hjc4604 Thank you for the info. It's the posting I was waiting for to learn what's the deal with the nitro.
You should always run nitrogen through the lines when you are brazing. It is a little extra time, but like Henry Chinery says it is to prevent oxidation and the soot build up form flaking off and flowing through the metering device.
Why are you not flowing Nitrogen. That's just a trade standard. Lacking that here.
A guy who is not afraid to get down and dirty to get the job done, is a good man!
Love that tube bender. Nothing beats a nice long radius bend.
Nice Brazing cant wait for a Bosch Review from you 💪🔧
That brazing is shit
Its so nice to see nitro being utilized. I myself like to purge the lines for about 1 minute and have noticed some time cut off my vac. Very nice braze sir
Voids your warranty if you don’t call Daikin on a warranty and they will look for oxidation in the pipe work, assuming the compressor is shagged.
ruclips.net/video/bjQ-cBtd-xM/видео.html
Nicely and neat. love when I tech knows what he is doing. Our pride in our workmanship is supposed to show on every job.
Good hands.good mechanic. We used spring type tubing benders. We called it silver soldering. Of course he de-burred the tubing. I cleaned my solder joints with steel wool while hot. Of course this was in trade school in the early 60s. Before I later became a Master Electrician.
Amazing install I am impressed
I partially agree with the setting of the flame. Part of brazing is getting the copper hot enough. The downside is a normal Neutral Flame is not large enough to cover the entire pipe (guessing 5/8”) i typically have the flame with oxygen set so the cone is at the brightest white which also elongates the flame. Then again, i’m not a field mechanic so what do i know. Other piece of advice is when in doubt about sensitive parts of the system, wrap it with a wet cloth. If necessary swap out rags between joint brazes
It is good to see you again Sir.
The best that I have ever seen. Smooth with it. For those who dislike what I just saw, HATERS, exist to let the best know that they are good.
Thanks Marvin, appreciate the support
This was good for me to watch a pro do a "good enough" install and I mean that honestly. Every field has the by the book way and the realistic way and as a DIYer it's hard to know where to put your energy. I am installing a bunch of mini splits and do all my own HVAC work so I'm no pro but I gotta be better than the average DIYer. I bought all the right tools, scale, micron gauge and so on as I think you need the right tool for the right job. The one thing I'll say though is this actually makes me feel a little better about flare fittings, I'm annoyed splits have them but I feel more confident that if done right they're equally good.
Mini splits have different filters for the refrigerant lines, they are not designed to brazed in. Flare fittings are used in all types of industries even sometimes at extremely high pressures. A proper install includes a pressure test. Its not a guessing game, whether brazed or flared, you have proof that your lines are solid before you ever introduce refrigerant into the system.
@@qomco I pressure test but only have the ability to test to 150psi because my gasses and regulators are all for welding.
You can buy a cheap set of ac gauges from Harbor freight or ebay. Idk how often you do this kind of stuff. 150 is honestly enough for most systems. If you have a bad braze or loose flare connection, you will see it leaking once you hit 20 to 30. By 150 you can pinpoint minor leaks with bubbles. I install mini splits and I only test em over 150 if the boss is watching.
I liked your performance, God bless you
Muito profissional seu trabalho. Está de parabéns...
I’m on an install team with an Hvac master and his buddy is an excellent tech and they both are teaching me. I’m pretty much a gopher atm but I’d like to be certified some day. Doing my homework watching closely in the mean time 💯💯
Go commercial industrial only way to fly
That was some quick work my man. I'd let you do mine if i had a actual working central unit.
We can you one installed, and them this guy come to swap it for one of the new amish brand. you got three choices Amish Goodman, Amish Traneman, or Amish Carrier.

plz subscribe my RUclips channel for HVAC maintenance video
Bad man, nice upload 👍🏾
Good Work! I did this in college and I succeed at this kind of course. Plus, I plan to join an apprenticeship program and learn more about pipe welding and brazing.
The young generation is not learning these skills or any trades for that matter. My two sons will be taught for sure. I'm third generation hvac service.
First generation commercial refrigeration services.
Thanks for the vid. Should be purging with nitrogen during the burn but very few do, glad you did :)
Keep up the good work
Why the use of nitrogen in such case or in HVAC services in general ?
griff Hall my son is 5, I asked him if he wants to do hvac like me. He Said no. I laughed and told him, “ buddy, you have no choice”
Learn it Live it Love it.
@@redakounbi7144 Purges oxygen from the inside of the tubing and prevents formation of copper oxide when heated. POE will dissolved the copper oxide and carry it through the system, potentially causing damage like clogging the TXV if equipped. Griff says "very few do" because R-22 systems used mineral oil as the lubricant which doesn't aggressively scrub the copper oxide like newer systems with POE so failures weren't as common.
All right nice video. Keep em coming. 👍👍
@Stephen glad you posted this brazing video.
Awesome and fantastic piece of work good job bro
Nicely done, flowing nitrogen and installing the dryer probably near the metering device. Perfect install.
Dan f16 dcc it’s probably inside the condenser
Nice job 👍
Wish my brazing was that smooth haha great job
Practice
The best that I have ever seen. He's smooth with it . Clean too.
Maquinote!!!!
Este tío sí pilota además se ve que esta haciendo una instalación muy profesional.
That wet rag is pretty cool, so the close end doesn’t get affected.
It's crucial when brazing due to the temperature required and high heat transfer of copper
Nice bending. Good video.
like that you used the gauge to provide extra protection to the valves. Also that hillmar tube bender looks nice! making me want to get one myself.
Amazing video
How does that help? Do you know? And is it just any end of the gauge?
Professional work
Very well! Can you give information about the tools, description and where to buy them?
Good job Stephen.....how in the world did this video get 600+ dislikes. I swear people watch videos to so they can find something wrong. Im an HVAC contractor here in Houston,TX and I've seen units installed wrong, I've seen plenty of hack jobs and some of the units defy what we were taught in the text books. How many blown compressors have you found from not reaming the copper lines? I use to work at a chemical plant here in town and the old timers never brazed with nitrogen and I mean never. In the 10 years I ran service out there I didn't see one TXV fail from being clogged up. I've seen power caps loose their charge causing the valve not to open. The reason I know is because those units are still running today. Im not saying don't ream or braze without nitrogen but when you've been in the game for a very long time you kinda know what you can get away with at times. Some of these comments are like these people live in a bubble or in perfect world. Once comment read "no capillary action".....I mean come on for goodness sake. Back in the day we were taught never charge with liquid because you can damage the compressor. Now supposedly you can't charge a blend unless you do it as liquid. I know if you do it slow it will boil off do to the heat of compression. So the text book people didn't know this back in the day. FOH! Bottomline you can't always take the "text book" to the bank.
Piss poor practice not using OFN.
Tattoo on
600 techs watched the video, who don’t want for homeowners to know brazing is easier than cooking cookies. Since lifespan of a/c system is 20+ years at most, reaming isn’t necessary.
You couldn't find some wrong with that installation? Is that the way you install AC in Houston? I'm sorry for those you worked for. This man just ignored the critical precautions that an installer should take to do a good job.
@@lewisfofanah3561 Yes, I could've found something wrong just like I found something wrong in your first sentence. You forgot the word "thing" after "some". They didn't teach you in school that it's good practice to proof read your sentences, paragraphs etc before you submit. You just ignored common grammatical precautions in your composition. Since you know so much, I have a question for you. On a multiple circuit evaporator using a txv, what would happen if you don't connect the equalizer line? Don't use google or youtube. I got another one for you. When replacing an oem 3 wire condenser fan motor with an aftermarket 4 wire condenser fan motor using a dual capacitor which motor leads would you use? I know you've installed a shit load of condenser fan motors so this should be easy.
Dude, I am beyond impressed. Great job!
Thanks for sharing!:) helped me
Really liked your video despite the hate i read in some comments, learned a few with ya, keep up the good work!
Thanks for the upload Stephen...probably best to disable the comments function anymore, as there's a lot of just simple random bashing that goes on by people who claim to be something they're not, and then those who want to argue with them. Just upload your videos and let people view them for the content. People should never claim to be an expert at anything, since they're really not...heck, even lifelong Doctors "Practice" medicine, so what can the rest of society possibly claim. It's nice to see a society of some folks who simply want to get out there and join the ranks of "Makers" our country was built upon. Good, Bad or Indifferent, your taking the effort to "Do" something, rather than be an armchair quarterback most of these responses are relegated down to. Best to you.....
Nice work transitioning trades from brick laying to hvac/r nice to see someone who Takes pride in his work! Get it from Ohio
Did brick masonry for a while, this change...... your back will be thanking you..
There's always best practices that make trade work dummy proof; but as an experienced brazer he did an effective job, if not the process they teach in school.
Great video Stephen!
Thanks skid
Lex Vance thanks my dear four vidéo
See you finally got a camera person
That's the way! Be Strong men!
Those hilmor benders are the best on the market. I LOVE them.
Going back to the root of things. Nice video. Thank you!
Stephen, I have a lot of respect for your knowledge. And here’s the “but” why didn’t you de burr the inside of each tube to prevent refrigerant turbulence or eddys. Or did I miss you doing it?
Old bad habits die hard, no other excuses
Why the hell would you debur refrigerant lines so you can chance killing your compressor in a couple years
There's little time to do everything "by the book". It would be nice but when you're out there in the 100F weather, covered in sweat, dirty, insulation itching your arms, you just want to get the install done.
A trick i use to get around deburring or reaming is to snap the copper pipe apart before you actually cut completely through it with your tubing cutter. Go around the pipe few times to make a deep score, then snap it apart using your hand. I found this keeps the hole bigger than cutting completely through it. Especially makes a difference when cutting 3/8 and lower.
Spector NS5 RD hmmm de burring only takes seconds 🤔
I was going to say that he didn't ream the pipes, also thought that the first with suction line torch was bit Orange I prefer more Blue Flame. Love the video, love the music all in all job well done.
Good job Stephen, your video is really helpful. You should take care of safety, you can get burn after you finish heating the copper pipe. I think you should wear safety gloves, that's much better for you. Finally, thanks so much for your video!
Real men don’t need no stinking gloves son.
Digging Hilmor, innovative and not overpriced. Cheers.
Almost perfect. Nice bender. I do not work in the industry, but just after you cut the pipe, it would be nice to deburr the pipe and make sure there is no small metal pieces in the pipe. Maybe the cutter you use doesn't make any, but I doubt that.
You’re right, should be deburring
I have the same bender as you and I have never had a bad bend until I bent some of that white anti ripp line set, I noticed it wasn't just mine that wrinkles now that I watched your video, seams like its made thinner to off set the price of the insulation jacket. What's your thoughts on it?
Use silicone spray or oil on the mandrel and shoes
I will need to try the oil the next time I use it. I've bent old copper never had a problem before, this is one of the reasons why I went with a Hillmore over the Yellow Jacket bending tool. The YellowJackets been known for wrinkles.
After about a dozen leaks I stopped bending it. The pressures are higher and the copper seems thinner. Bending just makes the copper weak.
I have the Yellow Jacket bender and it kinks and flattens the shit out of anything bigger than 5/8".
what bender is it?
That bender is an interesting tool. I worked supermarket refrigeration for years. We used hard ACR with fittings for everything. We rarely would bend pipe because any bends we wanted to make involved heating the copper up to anneal it. Then we would carefully bend it. That tool could've been useful to have for that job.
I have been able To Avoid buying any standard copper Fittings for many years since I bought this bender, I thinks it’s been more than 5 years. Thanks for watching
@@StephenRardon yes great bender. Ive got the yellow jacket version and it definately cuts down on fittings.
@@lesstech74 get the YJ swedge kit and you'll never need to buy a fitting again(for 7/8ths and less, they might make a bigger kit.) . Can be a PITA, but it works way better than the impact swedge kits.
Thank you I learn more about how installed new ac And Bracing thank you for sharing
Thought maybe this was an old video that popped-up on my feed
- glad to see more new content on your channel.
(...I know I've been slacking.)
What other benders do you have in your arsenal besides the hilmor benders...?
Don’t have other benders
Seen a couple comments on the rosebud. I just have to ask why? That's a lot of gas, and with the inconsistency of accetylyn availability in the past few months... otherwise looks good.
Yes... thanks
Great work you are doing a good job
I'm currently 3 years young in the HVAC industry (mostly residential), and for the past few months been doing brazing with 15% silver & copper brazing sticks. I've been taught to feed in the stick while brazing. In other words, while the joints are hot, feed in at an angle where it "sucks in" the braze stick to fill in the gaps as much as possible. You did a good job, I think, so I dunno why everyone is trippin...
There’s text book and then there’s real life. You notice the video didn’t say How To, just Brazing 🤷♂️
There that way and there is your way. If it can handle a pressure test, it will live the the life of the equipment.
Who needs Brazing, Solder or Zoomlock or Flares? Stephen , when you put an AC in Phil Swift's home you could just use Flex Tape and Flex Seal and be in a cool TV advert too! :)
Two part epoxy is the best
JB Weld with a smathering of Flex Seal over the top should do the trick.
Just found this video I was doing duct work now im on new construction this video has alot of cool lil tricks that I'll use thanks for the knowledge
That’s the best brazing job that I’ve ever seen
Where in this video does it show us start hitting the crack and booze . My fav part of running linesets
Dumb ass!
What Schrader valve core removal tool is that? Love the magnetic end!
HILMOR... 90$ I suppose...
I’ve been learning how to braze, flair, and swage in my new trade school that I go to. Best high school ever!
Excellent Work 🌹👍
Everything is easy when you know how to do it.
right
Nice bending work, good show of brazing with nitrogen and heat sinking the king valves. Really clean
Brazing with nitrogen? Wtf plantet are you on
Kg Glover when you braze your supposed to run some dry nitrogen thru the pipes to prevent oxidation
Not that hes using dry nitrogen to braze
Kg Glover clearly they mean flowing nitrogen while he braze.
Nice work . Love that technique and the bender. .
I think Steven Holmes
is joking or is insecure, your Brazing is ultra excellent (Wetting and Capillary actions were fairly achieved, means no gluing but base metals good welding) no extra drops of silfos, fast brazing preventing the valves from overheating, your flame intensity, distribution and distance control are exact. Woooow Mr. Stephen Rardon
Nice brazing Stephen 👍👍and expecially nice video the image was very clear...
Wonderful Brazing. Rgds from Hungary
Parabéns pelo seu trabalho... te acompanho a muito tempo. Gosto do que você tem publicado. Deus continue te abençoando.
Мне нравятся такие отзывы, нет злобы и высокомерия, я обычно стараюсь, дать второй слой, когда варю трубы..
i have this tube curving tool and i didnt know you could change the pieces and curve them to the outside.. very helpful tip, nice soldering bro! i would only change one thing there, i usually clean the male pipe with "scoth bright" or what is it called, or a fine sand paper and clean with clean rag before soldering and the second flame looks nicer and less carburant than the first one, a carburant flaming leaves more oxidation on the tubing, as well as too much oxigen which produces a more oxidant flame, which results in more oxidation on the tubing also. nice work! 💪
Nice braze, slick. I was waiting for that Hilmor to take a crap, but I guess I’ll have to save the other half of my popcorn for that, 😂 I noticed another comment about you being brave on using ole rosebud on the 3/8” line set, but they didn’t factor in experience, 😊
The pipes fit look loose before brazing, are they suppose to be that way?
Yes the linesets and suction and liquid line ports are all factory sizes. But sometimes you have to use a swedge kit and round the hole out more depends if your changing lineset or working off an older one when on the job.
Nice work BTW, looks tidy
Good job Mr 👍
Very nice ! Always fun watching a pro work !
What your brand of equipment do you prefer installing?
Bosch is my primary line at the moment
I'm jealous of your brazing. You can see it draw into the joint. 100%
