The air handler blower is the heavy-duty fan located inside the indoor unit that is responsible for pushing conditioned air through your home’s duct system. This component usually consists of a motor and a squirrel-cage fan assembly that operates at various speeds to maintain airflow. In high-efficiency Mobile Home Air Handler units, these blowers often use ECM motors to save energy and reduce noise during operation. If a blower fails, the evaporator coil may freeze up because there is no air moving across it to transfer heat. You can find replacement Motors-Fans in our parts department to keep your system running smoothly. The blower must be powerful enough to overcome the static pressure of the ductwork while remaining quiet enough for residential use. Regular maintenance of the blower wheel is necessary to prevent dust buildup from reducing its efficiency over time.
