What You'll Need
Flexible ductwork

If you want to  improve the airflow in your home without knocking through most of the walls, you should consider adding some flexible ductwork. This type of ductwork can move around the home without having to be inserted carefully, meaning that you don't have to adjust joists, or fit the ducts around stairs or other obstacles. Instead, you can weave the ductwork in and out of places, allowing you to use the most direct route possible. Installing flexible ductwork is easy, and if you have some basic home improvement skills, you should be able to perform this task within a day.

Step 1 - Arrange Your Flexible Ductwork

Before you start installing the ductwork in your home, you will need to make sure that it is long enough to fit into your walls. Check this by assembling the pieces in the room where you plan to start the ductwork, laying out all of the pieces until you have one long line. You can then measure the ductwork and ensure that it is the right size for the job. You can then check that you have enough space in your walls to fit the flexible ductwork, and that there are no insects in the walls which could bite or sting you. 

Step 2 - Begin the Hole

You need to make a small hole near the exit of the ductwork. You should make this hole using a hammer and chisel, as the hole doesn't have to be very large, only enough to fit the ductwork into the hole and support a hand or similar to guide it in. Make the hole enough of a size so that you can fit your hand holding the ductwork comfortably. You also need another hole near the finish of the ductwork of about the same size. 

Step 3 - Feeding the Wire

When you are ready to start installing the ductwork, begin by feeding a small piece of wire into the hole. This piece of wire will be long enough for you to feed it through the bottom of the hole, and then pull it up from the other hole. Feed this wire until it is attached to both holes, and then wrap one end around the ductwork, and pull that into the hole. The flexible ductwork should follow as you pull the wire through the space behind the wall. 

Step 4 - Finishing the Installation

Once the wire is pulled out the other side, you can fit your ductwork to the vents into the room, or to the outside, depending upon your needs. You can then seal the wall using a little caulk around the edges of the vents, holding the ductwork in place, and adding plaster around the edges of the room. You can then add more pieces of flexible ductwork around your home, simply making a small hole and feeding the ductwork where ever you choose.
