1. Trim dryer vent. If your dryer vent hose is too long, your dryer is working harder than it has to, using more energy than necessary. The vent hose should be long enough for you to pull the dryer out a couple feet from the wall, but the shape of the hose should form a line — it should not have a lot of slack, with twists and curves. A shorter, unobstructed vent hose increases the efficiency of your dryer, dries clothing faster and reduces lint buildup, which can create potential fire hazards.
Simply measure, mark and trim the hose to the desired length, then reattach the hose to your dryer and exterior vent. If you’re unsure about the hose length, check out YouTube.com for a quick video tutorial.
