How To Clean a Dryer Duct

One of the steps to maintaining a dryer involves the occasional cleaning of the duct system. If you allow it to go for long period of time without a cleaning, lint and other debris will clog it up, preventing the warm, moist air from exhausting properly. This may not seem like that big of an issue, but if the moist air can't escape the dryer, your clothes simply won't be able to dry. To prevent this from happening, you should take the time to properly clean the duct and remove and lint, debris or objects you find stuck inside. The 15 minutes it takes to do so could save you both time and money in the future; here's how you do it:


First and foremost, you'll need to flip the circuit breaker controlling the outlet where the dryer is, followed by unplugging the dryer. Flipping the circuit breaker isn't always necessary, but it's a safety precaution I recommend when working around electrical outlets. After you've done this, pull your dryer out a couple feet to give you some room to work with. Now that you're all set up, it's time to get down to business.

Remove the duct connecting the dryer to the wall at both ends. Most dryers use clam-shell clamps to hold the duct in place. If you see these on the machine or wall, gently unscrew and pull them off. If your machine is old or if someone else installed it, there's a chance that electrical tape could also be holding the duct on the wall or machine. There's nothing wrong with using electrical tape for this purpose, but you'll need to remove it to gain access to your machine and the wall.

By now you should have the duct removed with the interior to the machine and wall exposed. Get down on the floor, shine a flashlight directly into each of these areas to see if you notice anything clogging them. If you do, stick your hand up inside of it and pull out anything you see. Sometimes there will be huge balls of lint that have been accumulating for months stuck inside. Also, it's not uncommon to find articles of clothing that have somehow managed to make their way inside the dryer duct. Removing these items will allow you machine to work more efficiently and use less energy, which is something every homeowner should want. If your machine  still isn't working the way it should, you may want to hire a professional to come out and take a closer look at it.
