Is this a variable speed unit?

Yes, this is a variable speed unit, meaning it can adjust its output anywhere from around 25% to 100% capacity based on heating or cooling demand. This allows it to run at lower speeds most of the time for better efficiency, quieter operation, and more consistent temperatures compared to single-stage or two-stage systems. By modulating its output in small increments, it optimizes comfort, improves humidity control, and reduces energy consumption.
