The answer to 'air duct cleaning buildup' is that it is a common issue in many homes, caused by the accumulation of dust, debris, and even mold over time. This buildup can restrict airflow, reduce indoor air quality, and even lead to health problems for occupants.
Some common symptoms of air duct buildup include decreased HVAC efficiency, increased dust and allergens in the home, and musty odors. To address this problem, homeowners should consider having their air ducts professionally cleaned every 3-5 years, or more frequently if they have pets, smoke indoors, or live in a particularly dusty environment. While some light cleaning can be done DIY, it's generally best to hire a licensed and insured air duct cleaning company to ensure the job is done thoroughly and safely.
