Buying advice

When choosing a furnace replacement motor, first verify the horsepower (HP) required, rotation direction (clockwise or counterclockwise), shaft diameter and length, and mounting configuration. Also check voltage (typically 115V or 230V) and speed taps. For energy savings, consider an ECM like Genteq X13, but ensure compatibility with your system. For standard replacements, Fasco and AO Smith offer reliable options. Always confirm the motor fits your specific furnace make and model.
