The answer to 'lifespan of duct cleaning' is that the recommended frequency for professional duct cleaning is every 3-5 years for most homes. Regular duct cleaning helps maintain indoor air quality, improve HVAC system efficiency, and extend the lifespan of your ductwork. However, the actual lifespan can vary depending on factors like the age of your home, presence of pets, and whether you smoke indoors.
Homeowners should have their ducts inspected and cleaned by a licensed HVAC professional every few years to ensure they are functioning properly. Neglecting duct cleaning can lead to a buildup of dust, dander, and other contaminants that reduce airflow and put strain on your HVAC system.
