Your AC ducts play a crucial role in maintaining indoor air quality. Over time, dust, allergens, and bacteria accumulate in the duct system, leading to poor air circulation and potential health risks. Regular duct cleaning removes these contaminants, reducing allergies, respiratory issues, and unpleasant odors. Clean ducts also help your HVAC system run efficiently, leading to lower energy bills and a longer system lifespan. Experts recommend cleaning your ducts every 2-3 years, or more frequently if you have pets, allergies, or live in a dusty environment.
