Dryer Vent Clogged? How to Fix It

Image

A dryer vent is a duct or pipe that is used to vent the hot, humid air from a clothes dryer to the outside of a building. The vent typically consists of a flexible hose or rigid duct that is connected to the back of the dryer, and a vent hood or cap that is installed on the exterior wall of the building. 

The purpose of the dryer vent is to remove the moisture and heat from the dryer and prevent it from building up inside the home, which can cause mold, mildew, and other problems.

Signs of a clogged dryer vent

There are several signs that a dryer vent may be clogged, including:

  1. Clothing is taking longer than usual to dry: A clogged vent can restrict the flow of air, making it harder for the dryer to dry clothes efficiently.
  2. Clothes are still damp at the end of a normal drying cycle: A clogged vent can trap moisture inside the dryer, preventing it from venting outside.
  3. The dryer feels hot to the touch: A clogged vent can cause the dryer to overheat, making the exterior of the dryer hot to the touch.
  4. Lint and debris can be seen blowing out of the vent hood: A clogged vent can cause lint and debris to be forced out of the vent hood, instead of being properly vented outside.
  5. The dryer is making strange noises: A clogged vent can cause the dryer to make strange noises as the airflow is restricted.
  6. There is a musty smell coming from the dryer: A clogged vent can trap moisture and create a musty smell coming from the dryer.

It’s important to note that if the dryer vent is clogged, it can create a potential fire hazard, as the lint can accumulate and ignite. Regular cleaning of the dryer vent is strongly recommended to avoid these hazards.

How to unclog a dryer vent?

There are several ways to unclog a dryer vent, including:

  1. Cleaning the vent hood: The vent hood is the cover on the exterior of the building that the vent duct connects to. Remove the cover and use a vent brush or a long-handled brush to remove any lint or debris that has accumulated.
  2. Clearing the vent duct: Detach the vent duct from the back of the dryer and use a vent brush or a long-handled brush to remove any lint or debris that has accumulated inside the duct.
  3. Using a vacuum: Use a vacuum cleaner with a hose attachment to suck out any lint or debris that has accumulated inside the vent duct or vent hood.
  4. Hiring a professional: If the clog is severe, it is best to hire a professional to clean the dryer vent. They have the tools and the experience to safely and effectively remove the clog.
  5. Using a dryer vent cleaning kit: Some specialized cleaning kits are available in stores that come with a long brush, a flexible rod, and a vacuum attachment which makes it easy to clean the dryer vent.

It’s important to note that it’s also recommended to clean the lint trap after every load, and to have regular cleaning of the dryer vent to avoid any potential fire hazards.

How to avoid dryer vent blockages?

There are several ways to avoid blockages in a dryer vent, including:

  1. Clean the lint trap after every load: Lint can build up in the lint trap, reducing the airflow and making the dryer less efficient. Cleaning the lint trap after every load will prevent blockages.
  2. Use a shorter vent duct: A shorter vent duct will have fewer turns and bends, which reduces the chances of lint getting trapped and blocking the airflow.
  3. Avoid using flexible plastic vent ducts: Flexible plastic vent ducts can collapse and become blocked with lint more easily than rigid metal ducts.
  4. Keep the area around the vent hood clear: Make sure there are no bushes or other plants growing near the vent hood as these can block the airflow and cause lint to accumulate.
  5. Schedule regular cleaning and maintenance: Have a professional clean the dryer vent at least once a year, or more often if you notice any signs of a blockage.
  6. Keep an eye on the clothes drying time: If it’s taking longer than usual for the clothes to dry, it may be a sign that the dryer vent is blocked and should be cleaned.
  7. Use dryer sheets that are not fragranced: Avoid using dryer sheets that have fragrance as they tend to leave a sticky residue in the lint trap and the vent duct, which can block the airflow and cause lint to accumulate.

By following these steps, you can help keep your dryer vent clear and running efficiently, reducing the risk of a fire hazard and prolonging the life of your dryer.

When to call a professional 

It is recommended to call a professional to unblock your dryer vent if:

  1. You are unable to remove the blockage yourself: If you have tried to unblock the vent yourself and were unable to do so, it is best to call a professional who has the tools and experience to safely and effectively remove the clog.
  2. You have not had the dryer vent cleaned in over a year: Even if you do not notice any signs of a blockage, it is a good idea to have a professional clean your dryer vent at least once a year to prevent potential problems.
  3. You notice any physical damage to the vent ducts or vent hood: If you notice any physical damage to the vent ducts or vent hood, such as holes, cracks, or rust, it is best to call a professional to repair or replace them.

A professional has the equipment and the skill to clean and maintain the dryer vent properly, ensuring the safety of your home and the efficiency of your dryer.
