Air ducts are channels that transport airflow in HVAC systems. They are essential for maintaining proper indoor air quality, temperature, and ventilation. There are several synonyms for air ducts, including ventilation ducts, air passages, HVAC ductwork, air conveyance systems, and air distribution networks. These synonymous terms are used interchangeably in the HVAC industry, and each refers to the same essential component of air conditioning systems. Proper maintenance and cleaning of air ducts are crucial to avoid the buildup of debris, mold, and allergens that can negatively impact indoor air quality and compromise the efficiency of HVAC systems.
