Damaged Dryer vent hoses can contribute to higher electricity bills and hence it is important to inspect them frequently. Unfortunately, most people don’t inspect their dryer vent hoses until it’s too late. Periodic inspection and maintenance can go a long way in extending the life of your dryer and ensuring your overall safety.

As a general rule, you should inspect your dryer vent hose for signs of damage before things get out of hand.


Here are some obvious red flags which can signify whether your dryer vent hose is faulty and requires urgent repair.

  • Your clothes are taking longer than usual to dry and when they do, they are not cozy or warm. A damaged vent will restrict the proper flow of hot air from the dryer. When this happens, your dryer will struggle to function correctly, which can lead to a longer dryer cycle. Even worse, your clothes will still feel damp even after staying in the dryer for more extended periods.

  • The external dryer surface is too hot to touch. In addition, your clothes may also feel hot instead of soft and warm, which can signify hot air buildup inside the vent.

  • Typically, a functional vent hose expels hot air from the dryer and via the connection on the wall to the outside. If faulty, you’ll notice an accumulation of moisture on surfaces in the laundry room or around the house. With time, this can provide a suitable environment for mold to thrive which can impact the indoor air quality.

  • A burning odor or smell is another sign that all is not well with your dryer vent hose. As you already know, lint can cause fire and cause property damage, and loss of life.

After ascertaining that the vent is damaged, the next recommended step is to replace it.

detach the dryer vent hose from the dryer opening and wall connection.

Because you already removed the screws from the clamp in the previous step, now remove the aluminum foil that holds the hose opening on from each side of the vent connection.

After cleaning the openings, fit the new dryer vent hose over the machine aperture. Next, seal with aluminum tape and attach the clamp with screws.

Ensure it’s tight enough so that there’s no room for air to escape.

Now, cut the dryer hose to about six inches or longer, depending on the distance between the machine and the wall. Fit the hose over the duct opening on the wall. Then, seal with an aluminum foil and attach the clamp. Ensure that it is properly airtight for dryer efficiency.

Next, plug the dryer into an electric outlet and check whether the new vent works correctly. You can do this by inspecting the airflow from the outside vent.

Lastly, return the dryer to its position and not press it on the wall.
