The answer to 'why is my air duct neglected' is that air ducts often get neglected because they are out of sight and out of mind. Over time, dust, debris, and even pests can accumulate in the ductwork, reducing air flow and air quality in your home. Neglected air ducts can also lead to increased energy costs as your HVAC system has to work harder to circulate air.
Some common symptoms of neglected air ducts include reduced airflow, musty odors, and increased dust and allergens in the home. Regular cleaning and maintenance of your air ducts is important to maintain indoor air quality and the efficiency of your HVAC system.
