When air ducts are dirty, they can trap and recirculate pollen, dust, pet dander, and other seasonal allergens throughout the home each time the HVAC system runs. This constant movement of airborne particles can worsen allergy symptoms, cause respiratory irritation, and make it harder for those with asthma or sensitivities to breathe comfortably. Over time, the buildup of debris inside ducts can also affect airflow efficiency and reduce indoor air quality. Regular duct cleaning helps minimize allergen circulation, allowing cleaner, fresher air to flow throughout the living space.
