DIY: Vent Extender


In your home, if you have an HVAC unit, some time or another, you may have an issue that requires you to extend your vent. Here hiring a professional can help. However, it’s something you can easily do yourself. This is why here is an easy DIY vent extender tutorial for you. But first, let’s get you familiar with a few concepts.


Vents vs. Ducts
However, even though they are usually the same, they have a subtle difference, which most homeowners don’t know about.
A vent is an opening that allows air to pass from a duct into the room. A duct is a tube from which air passes through from the HVAC unit to the air vent. We understand that ductwork is the series of pipes that run throughout the house that delivers cold or hot air from an HVAC unit around the house.
It makes a vent, a slit or a hole that acts as an outlet from ductwork to a room. Unbelievably, air duct cleaning in Gainesville, GA, services knows this. However, they rarely mention the difference.


So, why the vent extension?
The main reason to use a vent extender is to extend vents, which improves air quality in a room.
How does it happen? Usually, ductworks are installed in walls or floors, and their vents are located someplace that doesn’t have open access to circulate air. To counter this, vents extensions are installed to regulate mood better in the rooms.


Vent Extender DIY – Things you’ll need


Installing a vent extender can be challenging, and DIY may not turn out great or clean as a professional did it. However, before any DIY work services like Air Duct Repair and Replacement in Gainesville, GA, recommend a few tools you’ll need.

  • Saw and cutter or utility cutter.
  • Pen or pencil for marking.
  • Spiral saw, or electric saw based on the area you’re working on.
  • Extension vent you’ll be installing.
  • Wood pieces, plastic or metal frame for vent extender.
  • Screws and nails.
  • Screwdriver, hammer, or electric screwdriver.
  • Extensive zip ties for securing insulation (if needed)
  • Vent collar
  • Metal tape
  • Space fillers (cardboard, wood pieces, silicon fillers, or foam spray filler)


Step 1 – Marking and Cutting
The first step is getting the place ready for installing vent extenders. Start by drawing a few inches of outline (6 x 10 inches or more) around the already installed vent that you want to cut. It will be the size of the new duct extender you’ll be installing.


Next, make sure there are no joists in the area, or it will be hard to cut there. After that, start with cutting the hole in the marked area carefully, ensuring it’s clean. Usually, DIY ones aren’t good, but you can do better. For cutting a hole, use a spiral saw following the lines you drew before. Once the hole is completed, keep the panel in place to avoid any insulation scattering into the room. Services like air duct cleaning in Gainesville, GA, can assist you throughout the DIY process if you need assistance.


Step 2 – Making a Frame
Now it’s time to work on the frame to go to the other side of the hole where the vent extender will attach. If it’s good ductwork, this step won’t be necessary. To check, see if there are holes where you will install the extender vent. There should be a frame already installed, usually made of wood or metal. If not, you have to install it.

Firstly, Installing can be time-consuming but straightforward. There is usually space where you will install the frame. Hence, Carefully insert pieces into that place and secure them with screws or nails. If there is a joist nearby, try attaching it there to ensure the frame is in place, Therefore, If you had to remove the duct outlet for installing the edge, you could do it, but make sure to put it back carefully without damaging it. Finally, don’t forget to install insulation after installing everything. Secure the insulation with zip ties. I almost forgot, add the register box to the frame you installed with the metal screws (preferably a ½ inch one)
This step may be a bit hard or confusing at times. You can ask for air duct repair and replacement in Gainesville GA service for assistance with directions if needed.


Step 3 – Installing starting collar.
Starting collar is what we install where the extension vent will go for attaching to the central duct. Its primary use is to provide a clean look to the extension vent. After adding the collar in place, we cut out in step one, add extra fillers (wood, cardboard, or some filling solution) to fill in any gaps. Make sure to secure it with metal tape or use a few screws.


Step 4 – Connecting the Vent Extension
Now, it’s time to add the extension vent inside the hole you designed in the previous steps. Here again, use metal tape to secure the extension duct or use screws if you have a place to connect it nicely. Now make sure there are no leaks and airflow is normal. Next, you can add an insulation jacket if the extension vent is too long, which is relatively easy to install. Again, use zip ties for securing inner duct and insulation, which is easy to install. Next, air duct cleaning in Gainesville GA service recommends using a zip tie again to connect the inner duct and outer insulation jacket (if needed).


Step 5 – Secure Register Box in the Room
The last step, go to the room and secure the register box. if you haven’t done it already. Use screws to attach it back, completing the new look of vent extenders. Next, check again for any leaks and paint the DIY vent extender according to the room’s ambiance.
