A dryer vent is a duct that carries moist air and lint from a clothes dryer to the outside of a building. It helps to prevent the buildup of heat and moisture inside the dryer, which can lead to inefficiency and potential fire hazards. Proper installation and maintenance of the dryer vent are essential for safe operation. Regular cleaning of the dryer vent is important to ensure it remains clear of lint and debris. Clogged vents can cause longer drying times and increase energy consumption. Homeowners should check their vents periodically and consider professional cleaning services if needed to maintain optimal performance.
