In what way does duct cleaning affect energy consumption in HVAC systems?

Duct cleaning can significantly decrease energy consumption by improving the efficiency of HVAC systems. When ducts are clean, there is less buildup of dust, debris, and other contaminants that can obstruct airflow. This obstruction forces the HVAC system to work harder to circulate air throughout the space. When these ducts are clean, the air can flow freely, reducing the amount of energy consumed by the system to maintain desired temperatures. Improved efficiency not only leads to lower energy bills but also extends the life of the equipment, as it does not have to operate under excessive strain. Therefore, regular duct cleaning is a crucial maintenance task that can lead to substantial energy savings over time.
