Dryer Vent Installation and Upgrades (Video)
Dryer vent installation can be a bit of a challenge. Keep in mind these rules of thumb. The shorter the distance and fewer the turns the better for dryer vent installation. Use no more than 25 ft. of 4-in. duct, and subtract 5 ft. for every 90-degree turn and 2 1/2 feet for every 45-degree turn for dryer vent installation.
