Small fresh air duct section install

[@karlaesquivel86]

Hi thanks for sharing. Where did you get that lift? I don't know what they're called but I need one for me..

[@SheetmetalHVAC__]

Hi Karla the lift is a genie lift also know as an “air lift” the lift uses carbon dioxide to erect the lift.

Thanks for the interesting videos. What do you call those cleats - S cleats or something else? And on residential we use drive and S cleats. Here you use only modified S cleats. What is the purpose of drive cleats? Do you know? I always wondered, why in residential not used S cleats on all 4 sides. Thanks.

[@SheetmetalHVAC__]

I have always called them slips or a slips and if it’s not a four sided slip connection I call it a slip and drive connection. But the way I was taught is that the connections of duct really depend on preference but its very common in residential because that’s what most supply houses sell from what I’ve noticed. The purpose of the drives which are usually on the left and right of the connections is to basically lock the two pieces together. I’ve demoed a lot of duct where people don’t even use screws just use the drives. A slip and drive connection is going to leak a lot more air which requires a bit more duct seal. I think slip and drive connections are quicker than all slip which is nice. On this specific project the engineers did not allow slip and drive connections they required all slip or TDC or TDF connections.

@@SheetmetalHVAC__ thank you. I hope you post more videos 😊 For some reason, there are not many sheet metal workers on youtube 🤔

[@amohvac27]

Can you please show us a close up of what exactly were you doing to the corners of the duct? Thank you Sir🤙

Hey man any chance of a video explaining how to make a 45 on square duct? Had to make a line rise up a bit friday for the first time. Im new in the trade and i want to learn more

Where did you get that tool belt it looks clean

Occidental leather

What's the proper name of that hammer?

[@SheetmetalHVAC__]

Riveting hammer

[@chrisbrown3357]

Are you using anything else to brace the duct other then just hanger strap? Like angle or uni strut?

[@SheetmetalHVAC__]

No. We are just using hanging 18G hanging strap with two screws on the sides and one on the bottom.

[@benjaminlenard38]

Hey boss what did you use to raise the duct

[@SheetmetalHVAC__]

Some people call it other things I don’t know what the correct term is but I call it an air lift or a genie lift. It uses CO2 and there’s a valve on a handle and long lines that regulates the pressure in the tubes and we use that to lift ductwork or heavy equipment. Holds up to 500lbs I believe

Is there a reason you don’t alternate the longitudinal seams from duct piece to duct piece? Is it because of the smaller size duct?

[@SheetmetalHVAC__]

Few reasons… main reason is that it’s a short end large end duct so it restricts me from being able to flip the duct to alternate. If it where TDC or TDF connections no problem. Another reason, runs are so short that there wouldn’t be much twisting on the run so it’s not much of a big deal for me. On bigger jobs though especially where it’s exposed we always alternate seams as much as we can to avoid racking and twisting of the run

[@timothyblaine2748]

@@SheetmetalHVAC__ right on and thanks for reply. Before doing a long run do you set your hangers and elevation before you start hanging duct? I like to compare what other tinners do to see if I can use any of it to streamline my work, so keep up the videos.

[@SheetmetalHVAC__]

@@timothyblaine2748 all depends on the job. Most of the time when I’m doing long runs I like to set all my hangers and make sure it’s not landing on TDC connections. Most of the time I like to set up a laser at the elevation and I’ll pre bend my hangers. Some times I’ll just set my laser and and hang until I hit the line. This can be done the same time your making your list as well so that when the ductwork arrives there’s hangers already set. I find it a good thing if you have people on site waiting for work and no duct yet.

[@ryans5803]

Was the s cleat all around a spec?

[@SheetmetalHVAC__]

It was a spec and it’s also per smacna and IMC standard because it needed to be a pressure tested at 3”WC if it was 2” WC I could have done slip and drive which would of been soooo much easier

[@idani4735]

Hey brother I’m an apprentice and I am wondering are those standing S cleats you’re using to make the connection?

[@idani4735]

Or is it ductmate

[@SheetmetalHVAC__]

What’s going on brother this is called 1/2” bar slip

[@MarcDiMillo]

That is a standing S cleat yes

[@adanescobedo6662]

I guess S is the way to go no more drive needed.

[@SheetmetalHVAC__]

Not necessarily, I would 100% prefer slip and drive and if I had more space I’d use TDC as well. But per smacna standard if the ductwork is pressure tested over 2” water gauge then you can’t use drives.

[@reefrepublik1440]

notch your corners next time to make it easier.

[@SheetmetalHVAC__]

The connection is a large end and small end all slip connection so it was already notched on one side. The less notches I need the less air leaking I have to deal with. On this project it had to be all aeroseal so everything has to be as tight as possible
