DIY Furnace Duct Work

There are many DIY projects that can be done with minor effort and if you keep up maintenance on it, you will never have to worry about it again. Your furnace duct work, for example, can be replaced, cleaned, and renovated once, then all you have to do it keep up with cleaning and maintenance so that you will never have to worry about major DIY furnace duct work again.

Keeping Your System Clean

Many minor problems turn into major ones when you neglect to keep up the maintenance on your furnace. The disposable furnace filter is the first line of defense to keep your furnace running smoothly. This filter fills up quickly during the winter months when the furnace runs more often.

What you will want to do is replace the disposable filter about every six weeks during the winter—but check to make sure if you will have to change it sooner. Depending on how hard your furnace has to work, you may have to change the disposable filter every month.

At least once a year you should also brush and vacuum the heat exchanger. This may or may not be recommended by the particular owner’s manual that you have, but it is a good idea to do this anyway. It will keep all the dust and dirt in your system from building up year after year.

Cleaning Your Furnace and Duct Work

Because parts can wear out faster on your furnace when it has to deal with a lot of dirt, you will want to make sure that the blower blades and duct work is all functioning properly and clean before each heating season.

Air leaks in your duct system is also another place where you can find that your furnace has to work harder in order to make up for the difference. If you have found a leak in your air duct, you can correct this problem by wrapping duct tape around the leak. Make sure to wrap it a few times so that you will have the leak covered.

If you find that there are too many holes and repairs that are needing to be dealt with, you can take off the existing duct work and replace it with new. This can be done relatively easily if you are willing to take the time to make sure there are not gaps or leaks in the new system once it is installed.


Remember your safety when you are doing furnace work. If you are opening the system, it is best to turn it off and cut the power from it. Even if you are only doing some cleaning, it is still better to be safe. Also, if you know that you have allergies that can be bothered by a lot of dust, it is recommended that you wear a mask when you are cleaning out your furnace and duct work.

Cleaning your furnace duct work is a simple way to keep your system running smoothly and heating your home for years to come.
