Inverter Compressor

A variable-speed compressor design that runs continuously at adjustable speeds rather than cycling on and off.

Definition

An inverter compressor uses a variable-frequency drive to vary the motor speed continuously, allowing the compressor to run at exactly the capacity needed at any moment rather than cycling between full-on and full-off. Inverter compressors are quieter, more energy-efficient, hold tighter temperature, and last longer than conventional single-speed designs. They are standard on premium refrigerators and on all modern ductless mini-split HVAC systems. The trade-off is higher upfront cost and a more expensive replacement when the compressor eventually fails.
