Air duct cleaning is the process of removing dirt, dust, mold, and other contaminants from the ducts in your heating, ventilation, and air conditioning (HVAC) system. Over time, these ducts can accumulate debris, which can negatively affect indoor air quality, reduce airflow, and cause HVAC system inefficiency. Cleaning the air ducts helps ensure your home or business environment remains healthy by eliminating allergens and pollutants. The process typically involves specialized equipment, such as vacuums and brushes, to thoroughly clean the ductwork. Regular cleaning can also extend the lifespan of your HVAC system and improve energy efficiency. It’s recommended to have air ducts cleaned every 3-5 years, though this can vary depending on environmental factors like pets, allergies, and local conditions.
