Furnace ducts are important in any house that uses a furnace for heating. Heat is dispensed throughout the entire house with the use of these furnace ducts. This is the main reason why you need to improve the quality of ducts you have around the house for you to have uniform heat circulation.

Step 1 – Evaluate Your House

In order for you to find the right kind of insulating materials for your home, you need to be able to know its heating requirements. Do you have any insulation between your walls? Are your windows and doors new, or are they old and vulnerable to drafts? Do you have a basement or not? Those are just a few considerations that you have to think about. Together with the dimensions of your home, use the information to know what the size of your ducts should be.

Step 2 – Plan Your Ductwork

Once you know the requirements to your ductwork, the next thing that you need to know is how you will be connecting the ducts together in your house in the best way possible. To do this, you need to be able to plan the route of your ducts in your house. This will be the only way for you to provide excellent heating to your house without pipes hanging around in every nook and cranny, at the same time you will be able to lessen the amount of work that you’ll be doing if you only have to follow a plan. You should also consider how you’ll be installing the ducts, whether you’ll be hiding them in between walls or underneath the floor.

Step 3 – Dry Fit the Ducts

Before you go on and permanently secure the ducts together, you need to first dry fit all of them together. Dry fitting is simply attaching the ducts temporarily. This is important for you to find out if all of the ducts can be assembled the way you planned. This step will also allow you to address any problem that may arise like a part of the duct that needs to make a turn or shortage of ducts.

Step 4 – Install the Ducts

When everything works out perfectly during the dry fitting process, you can go on to installing the ducts permanently by sealing all the seams with the use of duct tape. It’s important that you secure the seams properly to prevent any kind of leakage from happening. At the same time, it’s important for you to address the problem of sagging ducts. This usually happens if you have horizontal ducts that span more than a distance of 5 feet. You will need to install metal hangers or sliders to keep the ducts from sagging and eventually breaking apart.

Step 5 – Install the Ducts to Your Furnace

Once the ductwork is complete, you can proceed to installing it to your furnace according to the instructions in your furnace manual.
