How To Fasten Wall Register To Duct

This is the final step of our whole HVAC project, nosotros replaced the whole matter! Before we talked about if yous demand to supplant the HVAC in your home and installing a new trunk line. At present we are sharing the procedure we used to install an air duct to a room. If you lot just want to add an boosted air duct to a room, this volition help you run into the process!

THINGS TO NOTE: We are showing the process for our house, your house could be unlike. We are running our vents through the floor (ceiling could be dissimilar) in our basement. Plus we will be cutting through subfloor, hardwood, and carpeting to install the new vent.

WHY Nosotros ARE INSTALLING NEW VENTS

I explained our reasoning for installing new vents in a previous post about knowing if you need to supersede your HVAC system. Just I wanted to give you a refresher of why.

The placement of our onetime vents was not in the right spot. Making it difficult to heat or absurd our abode. The vents were on the inside wall of the house, instead of the outside wall.

And because of this reason we take today's post!

THE PIPE

Earlier I explain the install process I wanted to share some more than info on the supplies:

Pipage SIZE: This will depend on how much air you want coming into the infinite. The standard size is vi″ or seven″. But some other factor to call up nearly is what yous AC can handle.

VENT Take-OFF: This is where the duct volition start. It is where it is taken off from the body line. Non sure what a torso line is, see this post. Plus I have a video explaining the process of installing a have-off.

VENT BOOT: There are iii principal styles of a vent boots: xc degree, directly, or end. So brand certain y'all get the right style and size.

INSTALL AN AIR DUCT

The first thing you lot need to do is decide where the air duct will be placed. And then install the vent take-off off the primary trunk line in that location. See the details of installing a vent have-off.

Next, is putting the hole for the vent boot (where the vent will sit). Because we are working around floor joists and cutting a pigsty through wood, we decided to create a template. The template is the verbal size of the kick opening (4″x12″ is an example). So I drilled 2 1/4″ holes somewhere in the middle (for placing the template to trace). And I also drilled 4 1/eight″ holes in each corner (to secure the template to the subfloor).

Place the template on the subfloor making sure it'southward level on all sides (with the exterior wall mainly) and in the right location. And then attach the 1.25″ screws into the four corner holes of the template.

Afterwards the template is fastened, check to brand sure its level over again. Then drill a 1/4″ hole into the i/four″ drill holes of the template. (Yous will be drilling all the mode through the flooring).

TIP: We found it easiest to pull the carpet and pad abroad from the floor first.

Now remove the template and take it to the room y'all will exist adding the duct to. Using the two 4″ bolts, place the template into place and utilise the ane/4″ holes for the bolts.

We ever checked to make sure the template looked level with the wall. Just every time we adjusted the template we had issues installing the vent boot. So I would suggest leaving it unless information technology is really off.

Adjacent trace the outline of the template on the floor with a sharpie marker. Don't worry you will be cutting on this mark! Remove the template after.

Take the drill bit and drill a hole in a corner of the tracing (inside the rectangle). This pigsty is for your saw bract. Then using the Jig saw cut out the traced rectangle.

TIP: Take someone running the Shop-Vac while your cutting to collect as much saw grit every bit possible.

In one case the pigsty is cutting, it's time to exam the fit of the vent kicking in the pigsty. Accommodate anything if information technology is needed, we had to widen the hole just slightly some times.

Now let's install the vent boot into place. Starting at the vent take-off, add enough pipe for the distance to the boot. Nosotros liked to install 1 5′ slice onto the vent kicking get-go.

SIDE Note: The pipe will snap together to form a circle.

This is done past pushing the pipe and kick pieces together. And then added two or 3 1/2″ metal screws where they come together, this will agree them in identify. Then add duct sealant to all the seams (I didn't want air escaping!).

TIP: Pre-drill ane/viii″ holes on the vent boot to attach it to the subfloor (makes it easier later on). The vent kick will be level with the subfloor once information technology'due south fastened. We placed two holes on the longer sides (12″) and 1 for the shorter sides (4″).

TIP 2: Nosotros added duct sealant to the pipe seam after it was snapped together. Also, permit the sealant dry before touching or it could get everywhere.

OK back to calculation the pipe from the takeoff to the boot. You will probably need to cut a piece of pipe to fit. Practise this Earlier the pipe is attached together (it is easier to cut). Cutting information technology by using can snips and if needed use the crimper tool (this gives the pipe bumps to be able to fit into the other pipe).

Once you have all the pipage yous need, first attaching them together by only pushing (NO screws, all the same) starting at the takeoff. Insert the vent boot into the hole once everything is in place. And then attach the boot to the subfloor using the pre-drilled holes. REMEMBER the subfloor and boot volition exist level! Apply the 3/iv″ lath screws to adhere them together.

TIP: This is when the right bending drill attachment will come up in handy.

SIDE Notation: There is a cool product called Speedi-Kick that makes the install of the boot even easier!

After attaching all the other pipe together using two or 3 1/ii″ screws and so add together duct sealant to those seams.

In our house, we used woods to brace the pipe merely also support the flooring joists, we used the Kreg Jig and drill to install these. Please make sure to add together something to secure the pipe in place.

Now you tin can reinstall the carpet then cut a hole where the air duct is in the floor using a razor bract. And then your vent can be added to the room because your air duct is done!

You mayhap wondering if this whole project was worth us doing it ourselves. Yes, there are things that a Pro should help y'all with. Merely from the bids nosotros received, we saved over $6,000 doing this ourselves. Would that be worth it for you lot?
