Over time your dryer vent and hose accumulates lint and debris, reducing airflow. This results in longer drying times, lower efficiency, and sometimes even a fire or carbon monoxide poisoning. To prevent this from happening, it's crucial to check the dryer vent each year. While there are do-it-yourself kits and attachments on the market to remove lint buildup, the job is harder than it may seem. Some homeowners end up compacting the lint instead of removing it, which can make the problem even worse. For that reason, it's best to call in a professional for this job.
