Man, I wanna redo my entire duct system just for fun after watching these vids. Thanks dude.

In a field that no one wants to train, this is very informative. Thank you sir

People like you make the internet a great place. Thanks for doing this video. Extremely helpful.

Killer 🔥 videos! In the almost 15 years I’ve been doing this(service mostly) I have never once seen an actual training on wrapping round elbows. If y’all don’t know, this man is an absolute craftsman. And THAT is a dying breed. Bravo.

This guy is the epitome of an American guy 😅 Really great hands-on example. It's definitely not a piece of cake doing that on the field.

Watching you take pride in your work and profession gives me hope that someday I'll get a HVAC guy who knows or cares what they're doing. Great work my friend.

Someone who actually knows what they are talking about. Very refreshing.. and thank you for the information.

I just want to let you know you do excellent tutorials. You are a true master of your trade! You have definitely taught me a few things. Keep up the good work!

Finally someone who knows how to do a nice decent job. The people who did the house I live in needs to watch this video.

Andrew. I,ve asked my guy,s to watch your training video,s. Excellent, time-saving instruction. Thx !

Best video so far on how to do a 90. Typically run rectangle but had to do 18” spiral and the 90s were killing me.

Thank you for including the pattern dimensions too! I just started to insulate my home's hard pipe in the attic and I haven't been able to find anyone showing a "real world" method of creating a pattern for adjustable elbows with minimal seams and tape usage. I was also considering using the more flexible duct tape and saving the FSK for the long, straight seams, but didn't think duct tape would last in an attic - until I saw you apply the sealant over it. I like that idea!

I never even knew mechanical insulation was a trade in itself always thought the hvac guys/plumbers etc did it themselves. Started when I was 19 and 16years later still insulating its nice to see dif techniques though, respect!

Sir thank you so very much for putting these videos on KZfaq. As a new employee completely green to hvac, and working for my friends family business as an installer, just completing my first week of work, this is going to help drastically with increasing productivity. We are doing new construction on a retirement home where there are individual units in all the rooms, and im getting my feet wet in the trade with installing plenum boxes and making all the connections. There is a ton of rooms and not all the drops are exact so I'm unable to use the exact same dimensions for all my straight pipe between the 6 inch elbows. As well, not all the units are in the exact same spot in the closets, so I'm basically having to measure to fit every single one to ensure that I get a fllush proper fitting connection. Being new to the trade and also believing that quality is your worth, and being thrown to the wolves for on-the-job training, the methods that you're using and your attention to detail and in an easy-to-understand and comprehensible way is exponentially priceless. Take pride in what I do and I'm a fast learner and want to know everything there is to know about what I'm doing so has taken to you too and the internet to scour for tips to increase my value and productivity. This right here exactly what I was looking for and without rambling on any further I just want to say thank you. I can't wait to start work Monday using what I've learned on my second week and to see how drastically improves my production is going to be. I completed 4 closets total on my first week. I expect I could be able to very easily double or even triple that by the end of next week. Do you have any videos that you think I should check out as greenhorn new to the trade and things that I should know, please link me as I'm trying to gain as much knowledge as I can.

I am a heat and frost mechanical insulator this is a good way to do the elbow on a small pipe . I find it easier to insulate the elbow first. Then measure the straight insulation to fill in between.

I really like your motto, “Your quality is your reputation!” I’m challenged to find the balance between quality and being obsessive especially when I’m crunched for time. I guess that comes with time and experience.

Incredible! Not a single dislike and I know why!! Great videos!

For the first six minutes I had no idea how you make the final fitting work-- until 6:29 when it hit me. This is genius craftsmanship Super impressed-Again!

Nice pattern! Smart

Awesome tips Andrew. Thank you very much.

This is a very nice video! I have so much trouble insulating those 90's. That and my coworkers taught me to just take a 2 to 4 foot piece and just patch it together. And I hate doing it that way since it's ugly as hell. So this will definitely help me out a lot!

Great video Andrew. The Quality is always in the details. You’re a craftsman like our stuck van man commented and I respect and salute you! As an HVAC contractor in S.Florida there’s not much quality or sheet metal down here and I found your videos very helpful. Keep up the great videos and quality!

Great video!😊

So professional

Sweet I knew there was a certain way to insulate elbows and I’m glad I came across your video I like your method it’s cleaner

Thank you for this very informative video. A Big help for me since your attention to detail, showing the template cut and the taping process. Your video saved me a lot of frustration and prepared me for my project. Carry On Sir!

He's a Genius!

Thank you for your excellent explanation I really like and I enjoyed these videos; Would you make a video of how you connect all the ducts from the furnace to the registers,. The furnace the trunk and branches; that would be a excellent video. Thanks one more time. Nothing but excellent.

Thank you

Nice!

I take pride in my work as you seem to. I like my seams straight from one piece to the next, makes painting easier as well just different doing it in the air than on the ground. But your work looks good I dig it. I can't imagine having to wrap a 200roll job on the ground b4 hanging it though. I got a 350roll job atm va nursing home sheww. And the chillwater in it. Just myself and 3 other guys day in and day out slinging fiberglass! We do alot of outdoor duct as well usually armaflex or duct board followed by usually embossed metal over the insulation to watershed.

Nice

Your videos are incredibly insightful! Hope you keep them up; you’ve been my pseudo best friend & a huge help to me this week. Somehow I was able to create a modified template for a 45 elbow, which was incredibly shocking to me since my brain struggles with 3D visuals; kudos to your training method! Now I’m struggling with applying the same efficiency and effectiveness to a wye. And maybe I’m over complicating it, but my brain just can’t get there, even with scrap insulation to attempt. Any advice?

Nice work AGL! Clever how you did that also like the long scissors that's what i use in the field & always get strange looks lol

Also if you do any videos on laying patterns out for t's laterals etc in metal for covering chillwater pipes, roof drains etc I know plenty of ppl that would be interested. Not alot of ppl out there doing videos on how to insulate large t's and cutting metal gore 90's using dividers and measurements to cut patterns in metal covering that fit like a glove

The only thing that got me was watching you mastic tape. all the little sections of paper backing kills time. One big long piece is easier to clean up . But great video I can't wait to start using this knowledge. Also used your straight pipe video with my new helpers to study

now imagine doing this in a 5ft tall attic with 90f temperature

You do things a little different than we do but I have seen 90's wrapped this way. I find on round pipe anything 12and under I can pull a bit of fiberglass out bunch it tape it then pull the bottom around same way n keep it rolling if that makes sense.

Can you show how to do a 6" ridgid elbow

Love all your cheat codes. Thanks again Sir! Question if someone was doing 20" round spiral and it's to be mounted outdoors on a packaged unit exposed to the elements would you wrap it with something else after insulating it and masticking the insulation? What would that weather proof wrapping be called?

What staples are you using

Love that i came across this video, started doing hvac 2 yrs ago and duct is an area ive needed to work on. Thank you. Btw will putting masitc on fsk tape work?

What kind of scissors do you use?

Do you have content on take offs insulation on round square and saddles ?

Great video Andrew appreciate the knowledge I just got into the commercial side of HVAC here in Florida and the boss said if I feel comfortable taking this exact task on he’ll 80% of this quote on my check as a bonus.. I’m working with 9” elbows is the a method to calculate how wide to cut your first piece like how you cut 44” wide for the 12”?? If you could get back to me that would be greatly appreciated

If the duct is already installed , how will I use your method of insulation of round elbow?

My Ducting looks so bad after seeing all this. The company that installed it really did a half assed job.

What's the purpose of mastic outside the insulation? Ive never seen that here in rhode island.

Can i use 324a premium foil hvac sealer tape with backing on my insulation before mystic

But I'm an insulator by trade and wrap too much duct lol. Average 2to3rolls a day. Most all our jobs are 2.2inch 3/4lbs. 75ft rolls/300ft². I always cut a lap as well on the part I pull towards me to make my seam. And if something insulated to the left and right of me and I'm putting a piece between I cut a lap in the opposite side from the factory lap as well. We use minimal foil tape stationing the piece to hold it together pop some staples then fab my butt seam and horizontal seam all our jobs are fab mastic

How do you cut it when you’re in the air on a lift not on the ground

Can I just sleeve the elbow with scrap flex ?

Great training videos. I thought mastic first filled gaps then foil tape over it, then insulate. I see you’re using mastic to help hold the tape on over time. Any thought you have on if beneficial to mastic first or when to use different approach’s?

Hi Andrew, I admire your quality and professionalism! I am looking for an HVAC (heat pump) installer on the east coast (Boston area). Do you work on this area? If not, could you recommend someone you may know? Thanks, Fabian

What stapler are you using?

My question is how you playing with that insulation without any gloves or anything I go home itching if I just see insulation during my day

Why not do the middle of the elbow first? It seems like it would have saved a lot of issues.

Crazy how in industrial staplers aren't used. It's straight insulation and duct tape.

I've never seen silver duct tape b4 in my area, now i gotta have it. 🫡😎🍻

what if its already suspended?

great wrapping, not a clue why you would waste time and money putting duct seal on the outside of a vapor barrier, but i liked the wrapping job.

How are u not itchy from that fiberglass?😮

Sir you have vecancy I am hvac air conditioner duct fitter and 15 years experience Gulf country in Kuwait

Ur deff not suppose to duct seal the insulation. Ur suppose to duct seal the seams ON THE METAL, then u insulate it lol if u were hanging that youd be wearing that lol if ur worried about the tape not sticking bc of the duct seal on the metal, then simply duct seal the inside of the elbow b4 u insulate it instead of duct sealing the outside so u dont wear it and so the tape sticks and the insulation doesnt mess up the mastic seal

You are fired

Mask?

Butcher

Waste of time could’ve wrapped this thing in 2 min, tape down both of your ends just past the 90 that mess with the middle last tuck one end over the other and your good tape it up
