The answer to 'how long does dryer vent cleaning cleaning last' is that a thorough dryer vent cleaning can last 1-2 years, depending on usage and household conditions. Dryer vents should be inspected and cleaned annually to maintain efficiency and safety. Regular cleaning removes lint buildup that can cause fire hazards and reduce airflow, leading to longer drying times and higher energy costs.
The lifespan of a dryer vent cleaning depends on factors like the length and complexity of the vent, how often the dryer is used, and whether there are any bends or obstructions in the vent. Homes with multiple residents, pets, or high-usage dryers may need more frequent cleanings, sometimes every 6-12 months. Following manufacturer recommendations and having an expert inspect the vent annually is the best way to ensure it remains clear and functional.
