What are the symptoms of a clogged dryer vent?

• Long drying times: If you have to run your dryer for multiple cycles to dry a single load, it could be a sign of restricted airflow.
• Excessive heat in the laundry room could be caused by an overheating dryer
• A burning smell emanating from the dryer or laundry room could indicate lint buildup in the vent that is getting overheated.
• Clothes that are extremely hot at the end of the drying cycle may be a sign that the dryer isn’t effectively removing heat and moisture.
• Excessive lint buildup around the dryer or on the lint screen may mean that the vent isn’t allowing proper airflow.
• Condensation in the laundry room can be a sign of poor venting.
• Debris outside the vent could indicate a clog in the vent pipe.
• Unusual noises such as rattling or banging coming from the dryer may be caused by airflow restrictions.
• Increased energy use: A clogged vent forces the dryer to work harder and longer to dry clothes, leading to increased energy consumption and higher utility bills.

How to clear a clogged dryer vent

We have good news for you: you can clean your dryer vent yourself! With the right tools, it’s a relatively simple DIY task that can save you money and prevent potential fire hazards.

You should aim to clean out the entire length of your dryer vent regularly about once or twice a year to improve drying efficiency and reduce the risk of overheating.

1. Unplug your dryer from the power outlet. If it’s a gas unit, make sure to turn off the gas supply as well.
2. Carefully move the dryer away from the wall to access the duct and vent hose.
3. Use a screwdriver to loosen the clamp that connects the vent hose to the dryer.
4. Gently pull the vent hose off the back of the dryer.
5. Use a vacuum cleaner or a long vent cleaning brush to remove the lint and debris from inside the vent hose. Be thorough and clean the entire length of the vent hose.
6. Go outside and find the exhaust vent that lets the hot air out of the home. Remove any lint, debris, or blockages from the vent cap. Make sure that the vent flap opens and closes freely.
7. Once everything is clean, reattach the vent hose to the back of the dryer, secure it with the clamp, and push the dryer back into position.

Why it’s important to keep your dryer vent clean

By keeping your dryer vent clean, you help reduce the chance of fire and increase the lifespan of your unit. Here are more reasons to keep your dryer vent system clean.

Prevents fire hazards

Lint buildup in the vent is highly flammable, and if just a small amount stays inside, it can cause your dryer to overheat and potentially lead to a fire. Dryer fires are one of the leading causes of residential fires, and they’re often caused by preventable issues such as a clogged vent or lint trap.

Improves dryer efficiency

When a clogged vent restricts airflow, it makes your dryer work harder and take longer to dry clothes. Regularly cleaning the vent allows air to flow freely, which means your dryer can do its job correctly.

Reduces energy costs

When your dryer has to run multiple cycles to dry a load of laundry, it uses more energy, which can increase your utility bills. A clean vent helps your dryer work faster and more efficiently, which reduces energy consumption and saves you money.

Extends the life of your dryer

Few people enjoy spending a lot of time and money to replace appliances. Cleaning your dryer vent is one way you can avoid this hassle. Running your dryer with a clogged vent puts extra strain on the machine, which may cause it to wear out more quickly. By keeping the vent clean, you can prevent premature wear.

Prevents overheating and damage

A clogged vent can cause the dryer to overheat, which can damage the heating element and other internal parts. By keeping the vent clean, you can help your dryer maintain a safe operating temperature and nearly eliminate the chance of a dryer fire.

Prevents mold and mildew

When heat is blocked from exiting the home, it can cause excess condensation within the dryer venting system. Moisture buildup in a clogged vent can become the perfect environment for mold and mildew growth. If unchecked, this can pose significant health risks and negatively impact your dryer’s efficiency.

Reduces allergens and dust

We all benefit from cleaner air, and keeping a clean dryer vent helps prevent the spread of allergens, dust, and lint particles in your home. A clogged vent means these small particles have nowhere to escape, so they may be released into the air and lead to poorer indoor air quality.
