The clothes get tumbled in hot air, and the wet air is vented outside. The lint trap does most of the work by catching all the fibers (and pet hair) that come off your clothes, but the material that gets past the lint trap lands in the dryer vent. Even if you clean the lint filter after each load, your dryer vent needs to be cleaned once a year. Cleaning the dryer vent will improve how your dryer vent works.
How your dryer vent works
Most appliances in your home work for a limited amount of time - meaning that there isn't much you can do to prolong their lifespan. Your dryer is the exception - simple maintenance and an annual professional dryer vent cleaning can significantly improve your dryer's performance and lifetime. This is why it is important to understand how your dryer works.
Cleaning the dryer vent will cleanse the dryer vent system, removing all debris that build up over time. Cleaning the dryer vent is an often overlooked, but important step in maintaining your home or building. A good rule of thumb is to have dryer vent and air duct cleaning performed at the same time.
How your dryer vent works: Warning signs
Have your dryer vent cleaned if you notice some of the following problems:
- Clothes that take too much time to dry or laundry is damp when dryer stops during the cycle: (i.e. - more than one cycle when drying towels and jeans).
- Lint screen with no visible lint on it: Fabric produces lint, so excess lint build up on clothes rather than being collected on the lint screen can be a sign that the vent is clogged.
- Clothes hot after the dryer cycle, or the top of the dryer is too hot when in use: This is a warning that the dryer is working too hard due to vent build-up.
- Laundry has musty odor after the cycle: This is due to accumulated moisture in the dryer duct. Lint accumulation prevents the moisture being forced outside.
