Exactly. It's why I've never had and will never have a twitter account. It's just a venue for people to beat on strangers to make others pay for their bad day. That's about all these negative comments add up to as well; cyber wiping posts/wiping boys; beat up on someone else to feel better about their bad day/life. Fk em. Water off a duck's back....
I think the intent is often innocent enough, but they don't realise how disheartening it is to receive a constant barrage of "well I wouldn't have done it that way" comments. There is always more than one way to approach a problem, and we viewers are "in the backseat" - we might have the benefit of hindsight or more experience, but we cannot appreciate all the nuances of actually being there.
Well said its amazing though how many youtubers actually take it to heart. Most are just trolls with nothing better to do i must admit though a few videos back when he put the wires back in the wrong place I was yelling at the screen LMAO!
To expand on what @Paul Wehr said (I agree with you Paul), in my trade (electrical) Article 100 of NFPA 70, aka The NEC, states that “all work must be done in a neat and workmanlike” fashion. This means it must look good to the customer, and be done right as judged by the inspector. This work meets both of those - it looks good, especially where it’s most important to the customer.🤓 Nice work Chris 👍
Well, in general I disagree with the "looks good from my house" analogy primarily because I'm hypersensitive to those words - I come from a growing city where the Hackery is thick, near the Camp Fire burn scar... But Chris' work here clearly isn't that - I would like to say Chris used an *excellent application of good value engineering* - it looks great where it matters most to the customer, it looks efficient and functional where it doesn't show to the general public. If I catch one of my guys doing 'show quality work' on a roof we're gonna talk... Now there's a certain brewery nearby that wants the show quality work everywhere and they pay T&M for it - that's what they get. Conversely, I won't tolerate hackery except in emergencies wherein it will be subsequently repaired. That's my Sensitive Sally answer about that. Also thumbs up to your comment ;-)
Good job my friend, thanks for taking the time to make this video. Looks good, customer is happy and your company made money. No matter what you do haters are going to hate.
Don't put yourself down. You did a good job!! I was an electrician for 35 years and sometimes when you have to run pipes on top of the roof it's sometimes immpossible to make them look perfect. Especially using those stand-off blocks. You did a good job. You are a very competent professional!! Keep up the videos when you can. Love watching them.
Don’t beat yourself up. Trust me even if you think that job didn’t come out as well as you wished It did .your a man that really appreciates the trade . And that’s to be admired. Keep up the good work .Thank you
You made a conscious effort to get it right and job came out looking good. Give yourself a tap on the back and be grateful, because what you learned from this job will make the next one that much better.( It's a shared learning experience). Thanks for taking the time to do the videos and especially the recap.
I like watching your videos. I’m a tech on the resi side and it’s a change of scenery watching a commercial service tech. The shit you do is way out of my league respect for you brother!
Dude, you will always find something wrong with your own job! But let's be honest, that looks better than 90% of what's out there. Nice job dude, I like the p-traps outside the box! That way they're not hanging low in the box.
I’m addicted to your videos ! I’m in business where we do a lot of commercial refrigeration and your videos help out a lot when doing stuff another techs experience always helps and make jobs easier doing new stuff or learning new things ! Keep up the amazing work ! Love it
I think it looks pretty damn good. We’re always our own worst critic though. Knowing where to draw the line is what matters. Sometimes the time spent making it perfect isn’t worth it. Taking pride in your work is what’s important.
What is saw was proper techniques being used, and that everything worked correctly in the end. You do really good work, and always very thorough. I don’t think I would worry about the keyboard warriors. Thank you sir for all the knowledge you share. Keep up the good work.
@@HVACRVIDEOS LOL!!! Please. You did a splendid welding job! My favorites are the guys who get her cherry before they start. THAT bugs me. You? No complaints Chris....
Hey, this is looking perfect to me. I am watching this channel for 3 hours a day since I’ve found it and I must say that you’re just like me - using brains and not power to lift things. I am working in a totally different category - LPG/CNG systems on vehicles and we use copper pipes for the liquid phase of the gas, but really I saw awesome techniques that I tried today and worked beautifully. Love your work man, I really understand how these systems work and am striving to work with you, but im from a small EU country (Bulgaria) and will probably never happen. Keep up the nice work, I enjoy it and stay honest with your clients - thats why they choose you!
Regarding your torch cleaning procedure: A very easy and quick way to clean a torch tip is to dab the lit torch tip first on a piece of wood. The torch will pop, spit out the contamination in the process and relight on the smoldering wood. just try it, it literally take a second to do, works 95% of the time and you do not waer your tip down by sanding etc.
Actually that looks pretty good I love how you work you take pride and you have dedication a lot of companies put profit before anything. I also love the fact that you explain how you're doing things and why you're doing it a lot of hvac.r workers don't tell you anything or they ignore questions.
Yeah man you are way too modest! lol! You were like "I'm not perfect / it's not perfect", I was like "I cannot even begin to think what could have gone better wtf is he talking about?" Please link me your best job! I need to watch it!
Looks good from my house! I think it was fine man. I know if I was putting my work in front of thousands of people I would probably be the same way. Like you said there's always going to be stuff you could do differently. But you have a budget and a time constraint, other work and so on. Thx for the great video guy.
Love your work especially on the new roof piping. I am a retired refrigeration mechanic in Australia. I am surprised at how you do your swagging on the copper liquid lines on the roof. I used to use a flare press and hammer in a swagging tool into the soft drawn copper pipe. If I had to do a female joint on the hard drawn copper pipe I had to anneal it first otherwise it would split. I am surprised that Freon 22 is still used in Canada. It is absolutely forbidden to use any Freon refrigerant in Australia now. I used to use it all the time on my jobs here before it was banned because of global warming...Time passes, the Freons were a VERY efficient refrigerant and they ran at a much lower pressure too.
Not perfect John? Thats it I'm going to watch Steve Lavimonire's channel, Oh wait he is not perfect either. Darn your not perfect but your a great HVACR tech so I guess I will keep watching.because you care about the work you do and that beats perfection any day of the week.
Foam backer, bead, rod, or whatever name it has for the place you buy it from, it's great for filling a hole with minimal sealant. Like the tubes you have to fill I would get a foam coat it in sealant and shove it in, and I top it off with thin cap of sealant. Too much sealant can take forever to dry so this helps me. You could use the pipe insulation too, but having a small roll of it always comes in handy where you have to fill big gaps.
looking good bro no one is perfect i hired two union plumbers / pipe fitters for most of my piping job their great but they also do pipe work all the time its like second nature to them!
Have you thought about using zoom lock on jobs like this? I think it would speed up the process and definitely reduce brazing time. I have never used it but have read good things about it.
You already touched on the flooding back issue so your good. I would of used 3/8 soft 50’ roll. If you have another person just grab each end and pull hard then it will be as straight as an arrow. Works great
Looks good! Way better than most of the work you see nowadays. Just a fyi I dont know how you plan on finishing off the walk-in penetrations after the foam dries but our local metal supplier sells the same textured aluminum that the walls panels are made from and ive made patches from that to cover holes and trim out stuff before. Looks as good as it can for what it is. Even though on some old boxes it's polishing a turd. I've even used it to make covers to protect temp probe wires running across the wall to shield from getting ripped off from them moving boxes of product around. Just take a 3inch or so strip and put a 1/2inch kick on each side with a hand brake.
Thanks , I will be going live on TH-cam this evening 12/30/19 @5:PM (pacific time) to discuss my most recent uploads and answer questions from emails and the chat, come check it out if you can th-cam.com/video/XNnsDZUitZQ/w-d-xo.html
22:55 Took me a moment to recognize the spicy pepper place logo. 😀 I think this is the first time decoding this from one of your videos. 🥳 The line set looked like good quality work to me. 👍
Invest in rosebud tip. Blows hotter than both 1&2 tips and brazing 7/8 becomes like brazing 3/8 . I use same torches on 7/ 8 line and get done so much faster. Time saver and I think it save you save your gas too. If you know what your doing. Your better than alot of installers. Give yourself some credit.
I think it looks good! The material that was used gives look of quality to me. I like the tape(?) between insulation and clamps. Looks damn robust to me. I will do that next time I use Armacell. I am not a HVACR.
That looks fantastic, don't sell yourself short, you did amazing work as usual. I have nothing to do with HVAC and know nothing about most of what you're talking about (also, I'm English & live in the UK), I've just started watching your videos and find them really interesting and informative. (Could do with seeing temperatures in ⁰C as well though - seeing as we don't really use ⁰F over here). I completely understand your reasoning behind installing a new pipe set and taking it over the roof. Positioning the smaller pipes between the larger/insulated ones would've helped to protect them, but placing them on the outside actually looks better. I am curious as to why you didn't take the shorter and straighter route by running the pipes between the 2 roof units and straight over to the parapet wall. (Less pipe, fewer joints, less intrusive/more discrete and less exposed). I'm also curious as to why you wouldn't insulate all of the lines? Isn't there a risk of freezing in cold/winter weather? I know that British weather is different, but all external copper has to be insulated over here. Looking forward to watching more of your videos and learning more.
It’s not water flowing in the pipes so it’s not to protect against freezing. It’s to prevent condensation and to maintain efficiency through superheat of the vapor refrigerant
wish i still had some pics of a pipe job i did at a school gym about 18 years ago, unit was 40 ton i think. it had 2, 20 ton sections with inch and 7/8th liquid and almost 3 inch suction. had to run it about 60 feet. at the time 1 1/8"was the largest i had ever done on any job. it was a definite learning experience and was almost a work of art to look at. the engineer from york who came to do the start-up on the unit said it looked very professional compared to some he had seen. it was sad to see it all tore out a couple years ago when they built on and changed to all RTU's.
looks good to me, same amount of joints overall and works ;) in theory 5 or 500 joints shouldn;'t matter if they're all brazed properly, but eliminating them removes stress!
If I can give a small advice on camera work, try to zoom in slightly when you are reasonably close to the tarred plates on the roofs, like at 4:30. That tight texture will eat up the bitrate of the camera. Tom Scott's video called "Why Snow and Confetti Ruin TH-cam Video Quality" does a way better explanation than I can do. It looks fine in this case, but it's something that can catch you unexpectedly and it may seem like there's something wrong with your setup when you take a look a the final product when it was a simple pattern all along
[Whatever name goes here] if it's a static shot like that where the rough texture isn't moving it's not too horrible on the quality, but if it's a moving shot then the quality will definitely tank.
I'm curious about what gas mix you use to produce that greenish flame? From what I remember from my High School Welding class, a straight Oxyacetylene torch produces an intense deep blue flame.
Looks like 5-11 Stryke pants you're using? They make foam and neoprene knee pad inserts that work super well, that go inside the knee of the pants. They're super handy.
First of all, Great Job Chris ! Don’t let any negativity affects you in how should it be done or could’ve been better?, what you did right there look WAY better that what’s out there! Keep it up with good work and advices for new tech ! ✌🏻 Also, Have you think about using Pro Press fittings? They work really good, I used them a lot for refrigeration lines! Something you might want to check !
hey mate. do you draw the solder deeper into the socket for better penetration? also recommend cripping tool. so much quicker and rated to 4500 kpa sorry for metric
what size tip you using mate. i used to use size 8 to 10 and if need be i used a c shape burner which made life easy. i dont mind doing hard drawn pipe work.
Do you ever cut and make armaflex 90°s or just slide it on which causes creases. If they would have made 90°s do you think the insulation would have failed? Also are you using 1" wall on the freezer suction?
Oh and yes I love type L copper and sweeps and traps. I do bend all my own with Miller bender and I do a lot of SS work. 100 years is what I want my work to last for.
Good vid. ( Ftngot ) only thing i would have done differently is when i'm welding on a Roof / above the roof tar i like to throw a wet towel down to catch any hot drips onto roof. i allways have a Water bucket handy too with wet rags in it. i also like to have a garden hose around for safety.
Nice install - if for some reason you are using that style of supports and dont have enough room for the amount of pipes you need to run - just get some of that 1 5/8 unistrut and some 1/4 or 3/8 spring nuts and add a piece of unistrut to the top of your standoff .. it will raise your lines 1 5/8 inch but that is generally not a problem and is way cheaper than more of those supports - that type is pretty spendy. I'm sure you have seen miles of lines mounted on 4×4 with unistrut screwed to the top of it...
Chris, i Work in the Real World ! as do You. Your Work is Top Notch ! Do not Even think for One Moment that You do Sub-par Work. Your Work is Excellent ! This is Coming from a Guy that has been doing this trade since 1981 and Seen ALOT ! In 38 years. No one is Perfect ! Not even Me ! 🤣🤣 When We strive to Be the Best We can be at that moment in time. That Will be Plenty Good Enough ! Oc.
Youre too modest, that install looks aesthetically nice.
Agree. This is so nice&clean install!
Indeed
Man I would be happy with such a nice install.
But it's not a bad thing to wanting it to be perfect. That means you don't cut away much precision.
Don't let negative comments get you down - some people just cannot help themselves, and this is more of a reflection on them, rather than on you.
Exactly. It's why I've never had and will never have a twitter account. It's just a venue for people to beat on strangers to make others pay for their bad day.

Love your vids fellow supermarket tech out of Chicago your vids show we are not all hacks
Looks a lot better. I sometimes cut the back out of 5” downspout and elbow for covers.
or use pvc downspout and cut it lengthwise with power shears or saw, then simply snap it over all
Good install and better than most. Now please send some of that hot weather to London as it's quite cold here .....😂

That tight texture will eat up the bitrate of the camera. Tom Scott's video called "Why Snow and Confetti Ruin TH-cam Video Quality" does a way better explanation than I can do. It looks fine in this case, but it's something that can catch you unexpectedly and it may seem like there's something wrong with your setup when you take a look a the final product when it was a simple pattern all along
[Whatever name goes here] if it's a static shot like that where the rough texture isn't moving it's not too horrible on the quality, but if it's a moving shot then the quality will definitely tank.
I'm curious about what gas mix you use to produce that greenish flame?
From what I remember from my High School Welding class, a straight Oxyacetylene torch produces an intense deep blue flame.
Looks great if u ask me. Nice job!
Would a rose bud tip help on line size like that?
Looks like 5-11 Stryke pants you're using? They make foam and neoprene knee pad inserts that work super well, that go inside the knee of the pants. They're super handy.
Nice work! Thanks for sharing.
Great job again like always
First of all, Great Job Chris ! Don’t let any negativity affects you in how should it be done or could’ve been better?, what you did right there look WAY better that what’s out there! Keep it up with good work and advices for new tech ! ✌🏻
Also, Have you think about using Pro Press fittings? They work really good, I used them a lot for refrigeration lines! Something you might want to check !
hey mate. do you draw the solder deeper into the socket for better penetration? also recommend cripping tool. so much quicker and rated to 4500 kpa sorry for metric
what size tip you using mate. i used to use size 8 to 10 and if need be i used a c shape burner which made life easy. i dont mind doing hard drawn pipe work.
Never heard anyone say you aren't supposed to cool down the copper after brazing. Could someone explain? Thanks!
It compromises the braze joint and if done too quickly can cause it to crack
Do you ever cut and make armaflex 90°s or just slide it on which causes creases. If they would have made 90°s do you think the insulation would have failed? Also are you using 1" wall on the freezer suction?
Hi Chris keep up the good work
Thanks bud
Oh and yes I love type L copper and sweeps and traps. I do bend all my own with Miller bender and I do a lot of SS work. 100 years is what I want my work to last for.
Good vid. ( Ftngot ) only thing i would have done differently is when i'm welding on a Roof / above the roof tar i like to throw a wet towel down to catch any hot drips onto roof. i allways have a Water bucket handy too with wet rags in it. i also like to have a garden hose around for safety.
I also always have a water mister / sprayer .
Nice job Chris
On your 45 liquid line. Could you not have put a 45 in the next length with extra to allow for one swage and braze? Quality swage kit.
Great job! I would have covered liquid line on roof just because of the intensity of the sun's rays and rising heat waves from roof.
Good work. I am curious what it would have cost to have an insulation subcontractor re-insulate the lines in that confined space.
Nice job looks great 👍👍👍
HVACR VIDEOS Do you think piston compressors are more durable and resistant to extreme Hot whether than Rotary ones?
Nice install - if for some reason you are using that style of supports and dont have enough room for the amount of pipes you need to run - just get some of that 1 5/8 unistrut and some 1/4 or 3/8 spring nuts and add a piece of unistrut to the top of your standoff .. it will raise your lines 1 5/8 inch but that is generally not a problem and is way cheaper than more of those supports - that type is pretty spendy. I'm sure you have seen miles of lines mounted on 4×4 with unistrut screwed to the top of it...
Dude you look tired at the end take it easy, great job
Chris,
i Work in the Real World ! as do You. Your Work is Top Notch ! Do not Even think for One Moment that You do Sub-par Work. Your Work is Excellent ! This is Coming from a Guy that has been doing this trade since 1981 and Seen ALOT ! In 38 years.
No one is Perfect ! Not even Me ! 🤣🤣 When We strive to Be the Best We can be at that moment in time. That Will be Plenty Good Enough !
Oc.
Thanks Phil
Hey i think you did a pretty damn good job running that new copper
Thanks bud
Thanks for sharing
After watching a lot of your video's im curious why you don't use flash back suppressors on your torch lines
Good job well done
