    Sort of. The outdoor unit has to be multi stage or modulating but the blower and control needs to tell it to run multiple speeds or modulate too.

    A peek into the condenser will give you a hint: multiple compressors of course, but also a line entering the top of a compressor or what looks like a second power connector entering the compressor. I'm sure it's part of the model number, but we sell too many brands for me to always remember the significant character(s).
