A blower motor is an electric motor that powers the fan in heating, ventilation, and air conditioning (HVAC) systems. Its primary function is to circulate air throughout a building, ensuring that spaces are heated or cooled effectively. The blower motor can be found in various appliances, including furnaces and air conditioners. These motors come in different types, such as DC and AC motors, and can vary in size and power depending on the system's requirements. A well-functioning blower motor is essential for maintaining indoor air quality and comfort, as it helps distribute conditioned air evenly throughout the environment.
