While you can perform basic maintenance tasks to clean your dryer vent, such as cleaning the lint trap after each use, professional cleaning is recommended annually.
'While it’s possible to DIY clean your dryer vent, I recommend bringing in a pro who has specialized tools and experience to safely clean the dryer vent,' says Mallory Micetich, home expert at Angi.
These tools can thoroughly clean vents, removing accumulated lint and debris that DIY methods might miss, so for a thorough clean, consult a professional.
