Clogged dryer vents are a lurking hazard that most homeowners do not consider when performing basic upkeep. However, lint is a highly flammable substance and any spark from the dryer can cause ignition. It should also be noted that gas dryers have an added risk of carbon monoxide leakage if lint has backed up in the duct work.

The National Fire Protection Agency recommends annual dryer vent cleaning. In addition, it is recommended that dryer vents with a vertical design be cleaned twice per year.

How to Tell It’s Time to Clean Your Dryer Vent

Locate the dryer termination point (on the outside of your home) and peek inside. If you are seeing a buildup of lint in this area, you can be assured that there is a build-up throughout the entire ductwork.

  • Laundry room feels stuffy and humid
  • Indicator light on dryer is flashing

Sonic Air Duct provides free dryer duct cleaning service (up to 6 feet on ground floor) with all of our air duct cleaning packages. Dryer vent cleaning can also be scheduled as a stand-alone service. Our technicians use rotating brushes inside of the ductwork to stimulate and remove lint and debris from the system. It is a highly effective process and will result in an immediate decrease in fire risk and increased dryer efficiency. If vent exits through the roof or on the second floor and above, the cleaning may only be performed from the interior.
