Dryers are one of the most reliable home appliances around—they rarely have issues and can last for 13 years or more. However, to ensure your dryer has a long, functional life, you need to keep it properly maintained.
One of the most important aspects of dryer maintenance is keeping the dryer duct clean and free from lint. Lint buildup can decrease your dryer’s efficiency, causing it to work harder to dry your clothes. Overheated lint in and around the duct can even pose a fire risk!
Our guide will walk you through the steps to thoroughly clean your dryer duct and help prolong the life of your dryer.
A dryer duct or dryer vent is a pipe that connects the dryer to the outside of your building. It allows hot, moist air to escape and prevents moisture from building up inside your home and causing mold and mildew.
A dryer duct is usually vented to the outside via a vent on the wall of the building. During the dryer’s operation, hot air, moisture, and lint particles travel through the dryer duct to the outside. This prevents moisture from building up in your home and also ensures lint does not build up inside your dryer.
When a dryer duct has not been cleaned for a long time, it can get partially or even completely blocked with lint. This means that the hot, moist air can’t be properly removed, which can cause the dryer to be less efficient. It can also lead to fire risk, as more lint particles remain in the dryer.
It’s hard to tell if your dryer duct needs cleaning without disconnecting it and looking inside. However, dryer ducts should be cleaned regularly, so if you haven’t cleaned yours within the last year there’s a good chance it will benefit from a thorough clean.
Before you begin cleaning your dryer, ensure you have the following tools on hand:
For safety reasons, always disconnect your dryer from its power source when you’re doing maintenance work.
First, locate both ends of the dryer duct. You will probably have to move your dryer away from the wall to get access. One end will be attached to the back of the dryer, and the other to the exterior vent.
The connections will vary depending on your model and type of exterior vent. Most ducts are attached to the back of the dryer with a clip or clamp, but it may also be held in place with duct tape. This will need to be replaced once you’re finished cleaning.
Inspect the duct and its connections carefully before beginning to remove it to ensure you don’t accidentally do damage.
Before you clean the dryer duct, don’t forget to clean the lint trap! Think of the lint trap as the first “stopping point” for lint on the way to the duct—if the trap is overly full, lint is more likely to end up in the duct.
To clean the lint trap:
There will likely be a buildup of lint around the exterior vent where the duct attaches to the wall. Use your vacuum’s hose attachment to get rid of any lint and dust buildup around the vent.
When you remove the duct from the dryer, you’ll probably notice lint buildup in the duct housing, particularly if it’s been a long time since you last cleaned the duct. Use your vacuum cleaner to thoroughly clean away all visible lint.
Now it’s time to clean the duct itself! This process will differ depending on how long the duct is.
Reconnect the duct to the back of the dryer and to the exterior vent. Clip or screw the duct back into place at both ends, ensuring it is held firmly in place.
Return the dryer to its original position, then restore power.
You should clean your dryer vent every 12 months in order to maintain optimal drying performance and reduce the risk of fires. If you have a large family and use your dryer multiple times a day, you may need to do this every 6 months.
It’s also essential to clean out the lint trap every single time you use your dryer. This will prevent lint from getting to the dryer duct in the first place and is also a great way to ensure your dryer is operating safely and efficiently.
