The answer to 'what does dryer vent cleaning cleaning include' is that dryer vent cleaning is the process of removing lint, debris, and other buildup from the exhaust vent that carries hot air from your clothes dryer to the outside of your home. This includes cleaning the vent pipe, the exterior vent cover, and the area around the vent opening.
Proper dryer vent cleaning helps improve the efficiency of your clothes dryer, reduces the risk of fire hazards, and extends the lifespan of your dryer. It's recommended to have your dryer vent professionally cleaned once a year or more frequently if you notice any issues like reduced airflow, longer drying times, or visible lint buildup.
