As far as figuring out how often a dryer vent should be cleaned, a few factors will need to be considered. For instance, how long is your vent. Longer vents don’t exhaust as well, and thus build up more lint. Vents with a lot of twists and turns also have a tendency to have lint build up more quickly – in fact, each 90 degree elbow effectively adds 5 feet of distance to the venting system. On the other hand, a very short vent will often need very little cleaning. Also, older dryers tend to dry less efficiently, so you will want their vents checked more often.
The U.S. Consumer Protection Agency has laid out several guidelines regarding dryer vent cleaning. One of their biggest recommendations is cleaning the lint tray after each use. Besides drying your clothes faster, it will reduce the buildup of lint at the source of the heat. They also strongly suggest replacing older duct material that is flexible with the newer types of rigid or semi-rigid duct. The older duct material’s flexibility is more prone to kinks, which leads to restricted airflow and lint buildup and vinyl is not an approved material for dryer exhaust components.
