Blower
A blower is a key HVAC component that moves air through ductwork to distribute heated or cooled air throughout a building. Powered by a motor and fan assembly, it circulates air through filters and across heating or cooling coils, helping maintain comfort and indoor air quality. Some systems use variable speed blowers that adjust airflow for better efficiency and humidity control.
