Video: Why You Should Upgrade Your Dryer Vent

Choose the Shortest Route for the Vent

1. From an Underground Basement

• If your dryer is in the basement and the basement is underground, run duct up the exterior wall and out the rim joist.
• Set the vent a minimum of 12 inches above the outside ground.
  • Pro tip: Use no more than 25 feet. of 4-inch duct, and subtract 5 feet for every 90-degree turn and 2 1/2 feet for every 45-degree turn for dryer vent installation. For example, a dryer with a 90-degree elbow at the exhaust port and another at the top of the basement wall can run a maximum of 15 feet.

2. Straight Path From the Basement

• If the dryer is against an exterior wall that is not underground, run the duct straight out from the back of the dryer.
• Set the vent a minimum of 12 inches above the outside ground.
  • Note: This is the simplest, most ideal solution. The shorter the distance and fewer the turns the better for dryer vent installation.

3. Through the Attic to the Roof

• If the dryer is an interior room of the house, vent through the attic to the roof.
  • Note: Vent a dryer through the roof only as a last resort. Cleaning lint buildup from roof vents is difficult, and nesting birds and squirrels often find roof vent caps irresistible.
