The National Fire Protection Association (NFPA) recommends cleaning your dryer vent every two years. However, if you notice that your dryer is taking longer to dry clothes or is overheating, it's time to clean it out immediately.

It should be cleaned every 6 months. Dryer vents can become clogged with lint over time, which can cause the dryer to work harder and may increase the risk of a fire. By cleaning the vent every 6 months, you can help ensure that the dryer operates safely and efficiently.
