I know their are lots of Multi-compressor units that switch between the small and the large, or possibly both compressors, but does anyone make a Truly Multi-speed residential unit under 4-tonns?
I already have a multi-speed fan via the fan-handler unit that matches air-flow to temperature differential. It is better than the "2-speed" units that go from quiet to a roar and nothing in-between.
Just curious....

Some of the 2-stage condensing units are (2) separate compressors.....timed out
