142R Motor maintains its high efficiency across a range of operating speeds, which results in a significant reduction in energy use when the motor is run at reduced speeds. This makes the 142R Motor ideal for use in creating two-stage outdoor compressors and heat pump-type units. In addition to reducing electrical use, two-stage compressors feature enhanced humidity removal, less temperature swing between cycles, more even temperatures throughout the home, and quieter equipment operation (especially when combined with a fully-variable ECM ThinkTank™ indoor blower motor).
