The answer to 'air duct neglected' is that neglected air ducts can lead to a variety of problems, including decreased indoor air quality, increased energy costs, and potential health issues. Symptoms of neglected air ducts include dust buildup, musty odors, and poor airflow throughout the home.
The main causes of neglected air ducts are lack of regular cleaning and maintenance, as well as damage or deterioration over time. Homeowners should clean their air ducts every 3-5 years, or more frequently if they have pets, smoke indoors, or live in a dusty environment. Neglecting air duct cleaning can allow pollutants and allergens to accumulate, which can aggravate respiratory conditions like asthma.
