What is the function of a blower motor in an air conditioning system?

The function of a blower motor in an air conditioning system is to circulate air over the evaporator coil. When the air passes over the evaporator coil, the blower motor moves the warm air from the indoor space across the coil, allowing the refrigerant within the coil to absorb heat from the air. This process cools the air before it is distributed back into the living space.

An effective blower motor is crucial for maintaining the efficiency of the air conditioning system, as it ensures a consistent flow of air and proper heat exchange. Without this circulation, the refrigerant wouldn't efficiently remove heat, leading to poor cooling performance. The role of the blower motor is critical in ensuring that the system operates effectively to provide comfort within the conditioned space.
