The answer to 'how long does dryer vent cleaning last' is that a professional dryer vent cleaning typically lasts 12-24 months, depending on factors like the size of your household, how often you use your dryer, and the length and complexity of your dryer vent system. Regular cleaning helps maintain your dryer's efficiency, prevent fire hazards, and extend the lifespan of your appliance.
Homeowners should have their dryer vents professionally cleaned at least once per year, or more frequently if they notice any signs of a blockage, such as longer drying times or excess lint buildup. Proper maintenance can help ensure your dryer operates safely and efficiently for years to come.
