The Source1 2645705000 is a complete blower assembly that includes both the housing and the blower wheel. This unit is a direct replacement part designed for HVAC systems that require a full blower assembly swap. HVAC technicians and service professionals use this part when the original blower motor, wheel, or housing has failed or worn beyond repair. Replacing the entire assembly at once saves labor time and ensures all components are properly matched and balanced from the factory.
The blower assembly is the core airflow component in a forced-air HVAC system. It pulls return air from the space, moves it across the heat exchanger or evaporator coil, and pushes conditioned air through the supply ducts. When this assembly fails, the system cannot circulate air effectively. Symptoms include reduced airflow, unusual noise, or complete loss of air movement at the vents. A worn blower wheel with bent or damaged blades can also cause vibration and motor strain, leading to premature equipment failure.
The Source1 2645705000 replaces the full assembly in one step. The blower wheel is balanced to reduce vibration during operation. The housing ensures proper airflow direction and containment. Together, these components restore the unit to proper operating condition. This part is sourced through Source1, which supplies York and Johnson Controls branded HVAC equipment and replacement parts. It corresponds to the York part number S1-02645705000 and is intended for compatible York or affiliated brand systems.
Technicians should verify the model number and configuration of the air handler or furnace before ordering. Blower assemblies vary by motor horsepower, wheel diameter, and housing configuration. Using the correct part ensures safe, efficient, and quiet operation after installation.
The Source1 2645705000 blower assembly with housing and wheel is a complete replacement unit for HVAC systems requiring full blower section service. It restores proper airflow and system performance in a single installation step.
