Dryer Vent Cleaning Prevents Dryer Vent fires
The last thing you want is a fire to happen because your dryer vent is not properly cleaned. Dryer vents can be a source of dangerous fires in the home when backed up with lint in the exhaust line.
These backups or buildups will also cause your dryer to take considerably longer to dry clothing articles. Annual cleaning is recommended in order to assure that your dryer vents are clean and clear.
