Clothes Dryer Will Not Dry


We have an electric dryer and our issue is excessive drying time due to 100 feet of elbows and 4-inch vent ductwork. The contractor who installed our radon system told us to install a booster fan, but the HVAC contractor told us to shorten the dryer duct and add 6-inch vent ductwork instead. This would result in a total of 23 vs 100 feet. What should we do?


I like the idea of shortening the dryer vent duct and limiting bends. Increasing the size will also help if the connector through the wall is 6-inches. Make sure to use rigid, smooth duct and connections.

Adding a booster fan should be the last resort solution – it is just one more thing to maintain.
