The answer to 'air duct cleaning frequency' is that most experts recommend having your air ducts professionally cleaned every 3 to 5 years. This helps maintain good indoor air quality and ensures your HVAC system is running efficiently. The frequency can vary depending on factors like the age of your home, whether you have pets, and if anyone in your household has allergies or respiratory issues.
Regular duct cleaning removes built-up dust, dirt, and other contaminants that can circulate through your home's air. This not only improves air quality but also helps extend the lifespan of your HVAC equipment. Homeowners should consider having their ducts inspected and cleaned if they notice increased dust, musty odors, or a decline in airflow from their vents.
