There are several reasons why it is important to get your dryer vents professional cleaned. Many of them have to do with safety, maintenance, performance and cost. For the most part, we all do basic maintenance when we clean out the lint traps on our dryers in between laundry loads, but is that enough?
Lint can build up in more places than you think, that small dryer filter can get most of the lint but nowhere close to all of it. Instead lint can get trapped everywhere including the lint trap, the interior dryer duct, the dryer vent and especially the dryer itself. Unfortunately, this can easily turn into safety and health hazard.
As most homes have accordion-like foil or plastic vinyl dryer vents that are prone to extreme link buildup, there ridged shape quickly collects lint and easily restrict air flow. Therefore, making them a major fire hazard and putting additional pressure on your machine and its energy cost.
