According to the National Fire Protection Association, between 1999 and 2008, clothes dryers accounted for an estimated 399,800 fires annually resulting in 2,995 civilian deaths and 14,600 injuries each year. These fires resulted in an average dollar loss of $6,445 million.

When was the last time you had your dryer vent cleaned?

Lint and additional debris can build up in your clothes dryer vent and may cause your dryer to exhaust at less than optimum efficiency. This creates potentially hazardous conditions including carbon monoxide intrusion and the possibility for exhaust fires. If a gas clothes dryer is improperly vented or the exhaust duct itself is blocked by lint or debris, carbon monoxide can be forced back into your living space.

When a certified technician inspects and cleans a dryer vent, they also verify that the correct transition duct is in use. For example, plastic transition ducts (joining the dryer to the wall) should be replaced with the metal duct, because it is non-flammable, unlike plastic.

Annual dryer exhaust vent inspections (also known as dryer exhaust duct inspections) are more necessary than ever before due to the complex construction of homes built today. Newer homes tend to have dryers located away from an outside wall in bathrooms, kitchens and in hall closets which is convenient, but potentially dangerous from a safety standpoint. These new locations mean that dryers tend to be vented longer distances and vents are generally installed with more bends to accomodate the extended path they must take through the home. As a result, dryer ducts are harder to access and this additional length creates more places where lint can collect and animals and birds hide.

The Chimney Safety Institue of America recommends that CSIA Certified Dryer Exhaust Technicians (C-DET) perform dryer vent inspections on an annual basis to ensure efficient operation of your clothes dryer system. Certified Dryer Exhaust Technicians have passed an extensive exam on proper inspection and maintenance of dryer vents, including applicable codes and standards relating to these systems.
