What is the purpose of the blower motor in an HVAC unit?

The purpose of the blower motor in an HVAC unit is to circulate air through the ductwork. This component is essential for the proper operation of heating and cooling systems, as it ensures that conditioned air is distributed throughout the space, providing an even temperature and enhancing comfort. The blower motor pulls air from the living space, forces it over the heat exchanger in heating mode or over the evaporator coil in cooling mode, and then pushes it back into the ductwork to be delivered into the rooms.

This is a critical function because without the blower motor, there wouldn't be sufficient airflow to move warm or cool air into the living environment, which could lead to insufficient heating or cooling, decreased efficiency, and comfort issues for the occupants. The movement of air also plays a role in the overall efficiency of the HVAC system, as maintaining proper airflow can help prevent issues such as overheating of components or increased energy consumption.
