- Richard Trethewey is in the basement where the ductwork is being connected and installed by HVAC contractor Obie Rosa and his crew. Richard and Obie show Kevin O’Connor the tools used for bending, cutting, connecting and sealing the pieces of metal together to create traditional ductwork. Then the ducts get insulated.

After this 4 minutes video, I am ready to install ducting in my entire house! Thank you This Old House!
😂
Yeah sure buddy.
@@jasonbelozer4854 Just making sure you know its sarcasm 😅
Even if you're not ever going to do duct work it's still good to know how it's done.
so glad to see they are doing better work on the ducts these days. so many were never sealed up over the years.
I like Richard segments. Lots to learn and explained well.
Very well done video but the contractor was a little wrong on the explanation of the purpose for the wrap of insulation. The purpose of the insulation for ductwork is to prevent moisture build up on the outside of the ductwork when the system is in cooling mode because in an unconditioned space when cold air meets hot air it creates condensation in turn can create a problem for water. Yes it also helps to keep the air cool in the duct so that the conditioned air can make it to where it needs to go but the main reason is for condensation. I have seen so many jobs where people tell me they have a leak in there ac system and come to find out the original contractor didn’t install the ductwork correctly and didn’t take into consideration the environment of where it was being installed.
no
In every home I’ve seen duct installed, it was never sealed that well. Good work.
That's because no one wants to pay for the labor or materials involved in that.
So true lol
@@CoasterCrazyy or no one had a Richard watching that it was done right
@@zefrum3yes this is the real reason. If homeowners and general contractors knew what to expect and inspect what they expect then it would be done right.
Would you actually be willing to pay for it? Or would you like the contractor to end up doing volunteer work for you and everyone else?!
That's craftsmanship. Good job.
Outstanding job 👍
Excellent job, thanks for sharing with us. Fred
Richard is a certified expert in duct work.
Great vid..best I have seen and short...awesome
.
That's clean and perfect work
Ok that was pretty cool. Had no idea all that was done to make ducting.
This is the proper way to do it. I'm sitting here looking at my Grandmothers ducting in the joists of the basement as i type and the masting sealer, foil tape, insulation, screws, etc. are not present. This house was constructed over 50+ years ago though and many acceptable building methods of the era, while effective, are not acceptable in terms of today's professional contracting and construction code books and best practice reference manuals.
They still work however they are substandard.....
I thought 2 pieces like slid together didnt know you had to buy all that extra stuff
For numerous larger scale operations we typically use pre insulated duct boards. These are much lighter than traditional sheet metal and are fabricated in industrial shops like the one I work in. It's alot of fun! Especially since the Sheet Metal Trade is relatively small in my area. You get to know the guys from other shops, installers, and do so all under the brotherhood/sisterhood of the Union. If you want to see some more cool stuff you should look up Architectural Sheet Metal Fabrication/Imstallation (Building Facades and stuff like that).
Clean
Cool💯
This video had me in a trance.
That takes more skill then a I thought, good work. Skilled labor isnt cheap, cheap labor isnt skilled.
Problem now days is labor is neither cheap or skilled.
tubeonline629 and contractors are cheap to pay good skilled workers.
There's a difference between lack of skill and lack of license
A child could have done that…
Wow that’s a s cool I have never seen ductwork being done until now looks fun. But I bet that metal has to be sharp.
Sharp for sure
3:46 richard gets a lil stab :3
It’s not fun
@@Watson407 I was going to say that LOL
3:48 why you should wear a pair of good leather gloves dealing with ductwork
I saw that ! Richard couldn't get his finger away fast enough from that burr on the tin !!!
U mean 3:46
Cut resistant gloves might give you more dexterity compared to leather
wow.
This is what I do !
Interesting. I’m switching from baseboard heat to forced air very soon. Baseboard is getting too expensive and central air would be nice since summers are getting hotter where I live. I’ve always wanted to know how ductwork is installed and now I know. After around 20 years my baseboard heaters are nearing the end of their lifespan and I’m ready to replace them with something more efficient like ductwork. Great video!
Nice idol ilove ductman😍😍
It’s not a break , it’s a bar fold or cleat bender
It’s hand seamers.
It’s easier to notch the duct before you assemble it
Yup I agree.
Did to bother you too that he used the V notcher's on the duct seam instead of properly notching it.
little break, little hammer lmao. call em by there names
Thx. Would you have a video of strategy how you laying out the duct system for the whole house
Looking for the same thing
Not my job, but I like to watch.
ive never taped the seam like that before just duct sealer on the drive and ss
I never knew it took this long to make duct work. I never knew they made the duct on site. I thought it came in and they would just cut it the length they need. No wonder it’s so pricey to install central air
Thats great for that environment....but what about in a crawlspace. Thats what i need.
Thank you. I am now an expert and will hover over the installers that work on our home
Nice walkthrough! Never done this or even looked into it until now. Question: at 2:10 where he's hammering the drive cleat overhang to 90 degrees... would a hand seamer or other folding tool not work here as well? Is there a reason the hammer is preferred?
I was first taught to use my hand seamers for the bending of drive cleats. It’s a nicer fit and usually looks cleaner. Now I have used my hammer a million times to do the job. You will mostly be hanging duct and installing it in place. Sometimes it’s near impossible to get the top bend of a drive cleat. Hammer that every time
Very interesting and informative video. But this is assembling not installing.
Wow
It seems way simpler than I thought it was going to be.
A lot of thing will be simpler once someone who knows about it sharing it with you. Even Quantum theory is simple.
Noooo, the installation does keep the air in the duct the same temp but thats not what its foor, its to prevent condensation from developing on the exterior of the duct.
That's only true if the space its in is unconditioned, like there isn't a heat vent in the room. Say in the ceiling of a garage or a cantilever. Its honestly a waste to insulation so close to the furnace, unless you want to be hardcore and overkill it I guess
I don’t want the heat stay in the duct I want it out the duct lol
I'd never have duct work in my home . Either mini split or forced air. But they was pretty cool.
Fyi forced air would mean you have duct in your home
Even old " octopus" furnace had duct.
I was taught to put an "X" in the plenum to reduce noise
Cross brake. It makes the panel more rigid, which helps with noise from vibration or changes in internal pressure.
How to assemble ductwork
Watz dat stuff called da rubber compound?
@@khybersafi9137 oh k.thanx
Richard, this is something I am preparing to do. I don't know if you will see this, but maybe someone else who knows can tell me. I am installing a built in bookshelf and building a false wall (I guess that's what you call it) to hold that bookshelf. There is an air vent, so I need to extend the existing ductwork by about a foot. Is there an easy way to extend old ductwork without removing it? Can I just screw and tape it together with bending the pieces together?
Yes, there is. It would help greatly if you knew anyone who knew about the trade because they could whip up an adapter in literally 15 minutes. They might have adapters at the big box stores or stop in a local heating, plumbing place with a phone pic and some measurements and they should be able to help or direct you to a HVAC shop that can make that adapter you need ! Hope this helps.
@@augustreil thank you for the reply! That will make it easier than I had imagined.
@@brianmoore581, You're welcome, hope all goes well !
i techinition i need jop
i work in ac 14 years
how to apply i from indonesia
Appreciate it. Does anybody know the brand of mastic tape and insulation used here? Thanks
Dosent matter. Any brand will do
I got two rooms close to my Air conditioning unit that have sooo much pressure it's hard to sleep.
The 3rd area in the house has little pressure due to this. Is there a way to reduce pressure in the first two rooms?
You may be able to install a damper on the duct work or even an adjustable vent plateif you want to go really simple and cheap
Your ductwork may be sized improperly. It sounds like you should have a larger sized supply to the first conditioned rooms (to lower air pressure) and the 3rd room should have a smaller sized supply to help maintain velocity.
You need dampers so you can balance out the system and send air where you want it to go.
Imagine doing this for an entire house.
You won't, this is really for main trunk only, the supply branches are usually done with round duct from the trunk which is rectangular or square.
I thought you are suppose to leave an air gap between the duct and the insulation?
No- That is for the cellular reflextix junk- the "airgap" in that is part of the insulation performance. For fiberglass they did a great job installing it in this video- even as a contractor I would say this is top notch work. -Although I never like mastic tape, Just regular spread on mastic over fiberglass mesh mainly.
I've never seen drive pullers used on 10X10, 26 gauge metal before
We call those ladies aids, in the trades.😄
If you have to use that tool then you haven't done a good job setting yourself up lol. We always call people hacks when they had to use it.
No gloves?! What a baller!
I been in houses they just put a piece of sheet metal between studs they’ve come a far way lol
My Dad was a tin guy and I don't know if he installed duct this way or not. He retired in the mid 70's. Are these techniques that old?
Yes they've been doing it like this before the 70s, although probably not the insulation. Most old duct work wasn't insulated.
@@rawbacon Thank you so much.
Old duct work was insulated in asbestos
In my home they didn’t tape the joints or connections or insulate the ducts. Maybe that is not done in the north country?
teaglet 4:09-4:20
They should have tape the joints, you only need to insulate the ducts when its located in a space where there isn't heat being supplied too like above a garage for example
Working with razor sharp edges without proper protection gloves!!! Other than that it's a good demo.
Someone has to come up with a better way to control air flow. Duct work seems so primitive! I'm thinking someone could come up with a material that is self insulating (like an insulated, flexible plastic) that can be installed in less time.
Its not primitive at all, they have high efficiency furnaces now that are 95%+ efficient, so you're only losing 5% of the heat generated that gets exhausted out of your house when they used to be 50-75%. That combined with proper duct and pipe sizing and you have an extremely efficient way of heating your home. The way homes are built today they are very tight construction so very little air escapes your house so what they are doing here is way overkill. All you need is to tape, and only insulate were the space is unconditioned.
In a business sense all about cost, efficiency and labor. They have flexible duct that's already insulated but its very expensive and not very efficient (1 foot = 4 feet normal pipe), you could use plastic in theory but its extremely expensive in comparison to tin, although if you want plastic you can do a high pressure system but again expensive.
Supplies are best install with sheet metal. Returns you can use flex duct. Just make sure returns aren't installed at 180°.
Is this also called making “Fits?”
No
The only problem I see is you put the metal Tape over the duct seal which don’t give it time to dry. It’s actually supposed to be dry before you put the Insulation on
I was thinking the same thing, or reverse it Metal tape then seal It , on anything visible I mask off my lines with tape so I have clean lines, and This makes me Respect that bubble Wrap more than Ever.. lol
They didn't mention that there isn't no PPE needed😢
ditch the Square of you can . round has less air restrictions
Very true, but the dimensions needed for round compared to rectangular duct will have you making a much lower bulkhead. Example 10x8 duct is 8 inches high, an equivalent round could be 10 or 12 inches making your bulkhead 2-4 inches lower and that's will small duct
🤦♂️ the other tin knockers will understand..
I prefer to be called Tin Basher not knocker lmao
And also this video shouldve been titled how to fabricate ductwork
all tin knockers like this comment ! (im a commercial tin knocker myself)
I’m glad they made this segment.but let’s get honest.this was store bought duct cut to length.in the area I live in so many hacks do this and call themselves sheet metal mechanics.i have worked for the same small family owned hvac company for 31 years,and still lay all mine out by hand.we have a plasma table the younger guys use,but when it’s down they have no idea how to do by hand anymore.real sheet metal mechanics are hard to find
Im just a retro fit guy really and I'm trying to learn how to make more stuff myself. I just got a Pittsburgh on the break down. Now I need to learn more.
I always liked being called tin basher instead lol
Wow.....never screw the cleats....what if it needs to be pulled apart someday....
Pull the screws back out. They are not permanent.
@@mitchdenner9743 No he is right, they are intentionally designed to be a "break a part" connection, so if some of it falls down it can break away from the remaining duct instead of pulling that down too.
Cool, but change the video name to "how to put one piece of duct work together" you didn't install anything
why do you want to install ducts? Get ductless mini splits!
Some people don't want those ugly things hanging off their walls in every other room, I would guess ?
You have no clue
Alot of people don't want those big units hanging on their walls or the noise they make 🤷♂️
Scabs
Huh ???
2nd!
1st was a hack 😂I'm the winner y'all
Great little video, but they should be wearing gloves and the first thing this video should have told the viewer is to wear gloves when working with sheet metal like this.
Source: am Sheet Metal Worker
Step #1 wear a N95 mask...oh wait.
I got some on ebay for sale
I bought my house right before this whole thing. So many projects I wanted to do that will have to wait until next year probably because I dont want to sacrifice my lungs! Oh well.
That does not look fun.
It's not. It's sharp, messy and that's enough !
Who said it was? Or is it supposed to be?
Its fun if you like working with your hands and enjoy seeing the system being installed and how it looks afterwards.
No wonder that system is being abandoned. It would take forever to do a house like that.
No one who wants to make money does it like that, they were super slow and went way over the top, taping, duct sealing and insulating it.
Yet another misleading title. This shows how to assemble a section of duct but there is nothing about actually installing it.
no gloves!not safe work
If you know what you are doing and are comfortable then there isn't an issue with it. I know lots of guys that don't wear them and prefer it that way
Wrong.
This is the scab way of installing ductwork
first
Amateurs
Nice video guys..... but you didnt show how to install ductwork nor did you install any ducting . Maybe for the title " How to assemble , join and insulate new ductwork ". You wasted my time.
No way this is needed at all! Way to make people think this is necessary!!!
:55 "Each piece has a male and a female side" oops. I think you meant every piece has a non-binary, non-protruded non-indented sides.
Don't do your duct like that that is very wrong way too do that
That’s installing? Horrible
