What is the primary function of a blower motor in HVAC systems?

The primary function of a blower motor in HVAC systems is to circulate air through the system. The blower motor drives the fan that pulls air from the living space into the HVAC system, where it is conditioned—either heated or cooled—before being circulated back into the living area. This airflow is essential for distributing the conditioned air evenly throughout the space, ensuring comfort and efficiency.

Circulating air not only helps maintain the desired temperature but also plays a role in air quality by filtering and mixing indoor air. Proper air circulation is vital for the effective operation of both heating and cooling functions within the system.
