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.

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.

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).

@Anthony-nr1nd Жыл бұрын

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.

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!

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

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 !

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.

@CoasterCrazyy 2 жыл бұрын

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.
