Dryer vents should be cleaned at least once every year for families and once every two years for part time residents or two people households. Make sure the Company you hire to clean your dryer vent goes to the exhaust termination point of your dryer vent. That is where most of the blockages start, as you can see from these pictures. Hiring an experienced company is the most important part of getting your dryer vent cleaned correctly and efficiently.
