Repairing HVAC Ductwork In ATTIC 

I used to do this work years ago. Don't miss it at all. Much respect to hvac installers

Pookie covers everything. Remember do your best, pookie the rest!

Definitely the cleanest most professional work I’ve seen here on RU-vid. Great job man.

Such clean work on installing a new duct line off the trunk. I like how well you seal it as well! Great job! 💪🏼

Everything he did was professional that's what I'm talking about have pride in what u do to the start to the finsh

To skip the stop leaks in work truck 's roof comments go to to time: 2:41 Great HVAC info, Thanks!

They make duct straps (duct zip ties ) for the flex around the taps . Tape doesn’t do well in places it gets hot and then cold . It will come off eventually.

Always amazed at the range and variety of tools Americans have at their disposal.

Nice work I wish the attic’s were that big in so cal Especially old houses

Bro you’re so graceful with it lol! 🙌🏾

I love that little shockwave hole saw bit. It’s one of those tools that if I lose it - I immediately go buy another.

I respect that you work by yourself but utilise protective gear and take your time with your workmanship. Great job bro I'm by myself too and respect that you're not taking short cuts👍

I like that the attic you work are very big and you can do all that. there are houses where they only measure between 2 and 3 feet and there are already ducts and you have to jump to fix 😕

Thanks for taking that extra time for does awesome films. we appreciate that!!

Always a pleasure to see your work. Keep doing the quality work that you always do

I noticed how well your gloves stayed clean as well. I would have it every where.

Where I live it's all duct board , it's way easier then metal , but you do clean work

Very satisfying to watch and learned a few new little tricks very good video

It is nice to see Techs do duct the right way. Great video bro.

You may have a video on this, but i would love to know how you got started. Did you begin by attending a school? did you start with a owner operator? Are you in a union and if so what was your apprenticeship like? How many years have you been doing this and are you an owner operator? Sorry to ask so many questions, I just know discovered this channel and like your videos. I am going into HVAC and I find these videos very helpful.

Been looking for a reference video on how to cut the hole for a saddle take off. Thank you!

just started watching yiur channel today impressive bro keep it up I am a chill water technician from st Lucia Caribbean

Yummy!! Nice Ace Ventura shout out.

I would expect your channel to rapidly grow man, you are very informative and are a natural at talking to the camera. I'm hoping to get into HVAC and your videos are great info for me, it looks very challenging!

It’s satisfying to watch you work man 👍

Back to the days we could go in customers houses without masks! Good video brother

Great video

Your collars are different than the ones down here in Houston, nice video btw!! Keep up the clean work!

Late on this video. Noticed that there’s many ways people hook up ducts around the states Out here in Cali we use sticky backs which is the collar he had..so much better than the one with tabs..we put the liner over the collar, panduit strap(zip tie), mastic tape around panduit, flex tape it, then barrier over liner, zip tie again, flex tape one more time. Then air seal. Shits almost permanent💪🏽

Nice work on the duct repair quality work my friend

Another awesome video you’re videos are motivation 👏🏽👏🏽👏🏽👏🏽🤘🏽🤘🏽🤘🏽✌🏽

I just recently moved to a commercial/ industrial company and man do I not miss running flex in attics lol

Dude, you know what you are doing!

Best channel

Where can I go to learn more about ductwork installation? It was never really talked about at my school

being in the hvac industry for 15 years in Australia, not going to lie... but everything wether its hvac, ac refrigeration, electrical whatever it always looks so much harder in the usa, like use are legit 10 years behind lol

Rhino bed liner works great and looks good

Been enjoying your videos

Well done !!!! Cheers

What kind of tape do you use there? I need to tape some tear in my ducts in attic. Very nice vid. Thx

Great video can you do a video on what products you prefer tape mastic etc. 👍👍👍👍

One thing I’ve noticed you don’t put screws on the duct to the male connector tube. Instead you use foil tape. When I did all my duct hose I use both screws and foil tape. Don’t use duct tape on duct work lol

sliding the duct over the vent/register, then wrapping with foil tape, would it be ok to use a layer of mastic also on the vent, and then slide the duct over it?

nice job i wish my attics were that big

love your work wish you lived in mount airy nc i would hire you in a secert your fan edgar

Que produto é esse que vc está usando para fazer a vedação das frestas¿

Great work, now let's see that with a truss built roof with 4 foot max clearance.

Great job and video like always

Question sir, what is the name of the expanding foam you used at the end of the insulation sleeve? Would if be ok to use aluminum foil tape instead? I live In california if that matters. Your response would be highly appreciated. I like your work. Very clean and effective.

Why the mastic on the roof is a bad idea is because mastic is water based which means when the new rain storms come through it will wash all that stuff off.

Serious question, why do some collars have dampers and some do not? What are the benefits to having a damper on collar? Keep up the videos I’m lovin them

Great video.and work, You the man!

Yall do it differently than us in FL. I have never seen someone screw the flex down with screws

Great video. Is it ok to use cold weather foil tape 181A/B to seal around the register where it meets the sheet rock like you’ve shown here? I’m not sure if what you used is considered similar to the foil tape I have that I use with with mastic.

Nice stuff man, i’m 17, i go to a tech highschool and have been studying hvac for 3 years now, can’t wait to jump into the trade. But i’m wondering, is there enough cfm still so that you have a nice constant velocity between all supplies? I see you added more supplies, is the unit and fan big enough for those additions?

What kind of colar is that ? I rarely touch duct go easy on me lol

I miss the sound of the drill when screwing in the straps or grill or anything! 😏

I use 557 tape when connecting flex to the start collar then wire tie it with a wire tie gun then wire tie the flex after that

are there any lines going to the air handler that should be insulated, like the line that goes from the heat pump into the side of the house?

Do they duct blast where your at? All the mastic. Love the more film like tape for any flex work and ide still throw the straps over the tape. Maybe even on 2nd layer still, even with the spray foam altho that kinda blew my mind and hasta be considered over the top amazing?

We call mastick pookie here in Ocala Florida

Where is the volume control ? And how do you balance your systems? Also Duct in the USA seems very thin.

Man I wish I could wear a long sleeve shirt in an attic. It reaches a cool 115-120 up in the attics here in NY

I have high static pressure on a new 3.5 ton heat pump. I know for sure the flex duct is the issue. I have two 12" coming out of the supply in opposite directions. I know I need an 18" for a 3.5 ton heat pump. I did a diagram layout of the duct in the attic. What would happen if I just replace the two 12" to 18"? Ignoring the downstairs, because everything is between the walls. The problem was even worse with an undersized return. The original and only return was a 24x18. The total static pressure on the unit was .9 W.C. I was able to drop the TESP to .66 by making the return 30x24. Since there is so much static pressure and the unit TESP is a .2 and I need an 18" for a 3.5 ton for 1400 CFM. How big does the supply plenum should be and what shape? Should the supply plenum split to 3 18" going out to each of the 3 distribution boxes? Do the other three distribution boxes also need to be larger? Looking at the triangle shaped supply plenum I have very little room up for a rectangle plenum. I think a 3 feet ductboard supply plenum should work. There is a foot from the Air handler to the ceiling and I think 2 feet from the attic floor to the roof. Now I am looking at two types of designs. Design #1 keeps the 18" ducts straight by having a single 18" coming out of the supply and then a distribution box splitting it to three 18". The sides would be coming out straight to the to side boxes and one going to the third box with a slight curve. Design #2 splits to three right at the supply plenum and goes to each box individually, but all three will have a slight curve. I will not be using any metal plenums..... it will be all flex duct and ductboard boxes, because of budget. I am not trying to make a perfect system, but trying to remove the restriction from the 12" undersized ducts installed and replacing the flex duct that was patched with mastic with new ones. Another question about the installation..... I have the flex duct running up and strapped to the roof for support. Since the supply plenum is low to the floor due to the roof..... Can the flex duct be run on the attic floor? Can you tell me which layout makes more sense and less restrictive? Thank you.

First time I’ve seen flex strapped like that but hey if it works it works looks like you definitely seal it good. Nice work

Nice &good

Did those white mini split linesets corrode and form leaks in the copper?

What are your plans to grow...? You’re a Good Teacher, maybe you can teach one or two young apprentice your way for installation crew, to lite maintenance,then service...

Good work brotha as always

Should I always wear a mask when running flex?

Just curious why no use of duct strap (panduits)

Mastic on the atdrp won’t dry usually if you Insulate it right away

I like the Content. Good Channel Greets from Germany 💪

How do you like those malco snips ? In your opinion what are the best snips ?

Great channel!

Man you really make a mess with that mastic lmao

Very nice video my man. Question tho... is it code to use spray adhesive foam on the ducts? I just thought it was code to use like a 36 in zip tie

Do you ever use fiber lock for the fiberglass inside the duct just in case the fiberglass won’t go airborne?

What is that white seal paste you were using?

What kind of screws are you using to secure the web duct strapping?

What is that white stuff your putting around the ducts entry way?

I don’t know what type of mastic are you used to seal the leaks on your truck camper cause the mastic we use for ductwork is water base meaning that it is not water resistant so I don’t think that quick fix will hold up overtime

do you like the m12 tool or the m18 tools more? i think i saw you have m12 impact and m18 impact in other videos

Down here in Miami we don't have those attic only 3ft or 4.

Is it safe to put mastic in the interior fiberglass lining of that box?

Do you mostly work alone as an HVAC tech?

Good job!!

Bro my shirt would have been SOAKED! How do you sweat so little? Or why do I sweat so much?

That Aluminum ladder made me laugh? Time to upgrade

What mask do you use ?

I noticed that when you were installing the start collar, the manual damper handle is at the top. This is wrong. It should be either at the 3'o-clock or 9'o-clock position.

No panduit straps in your flex ?

wao how well you work, I would like to work with you to have more knowledge I am an air conditioning technician

That was my first thought that popped into my mind when you said your truck was leaking = HVACK guy Break out the mastic

Are the units to close together? Or is that okay? New tech here.

When you attach your flex to your collar how come you don’t use Panduits with your tape I was taught to do panduit on inner flex and tape on top of panduit then slide insulation down and put one more panduit

Do you have a helper you use for big job or do you prefer to work alone...?

I have good Experience for duct cleaning. how I can work with you .

You don't use 36 inch zip ties on your duct connections?

How much does it coast to repair and air conditioning duck
