My previous home had a Carrier with a two speed compressor. It ran at half speed most of the time and only kicked into full speed in the late afternoon. The advantage is the system ran continuously from the mid morning to late evening so there was no cycling, which is hard on the system. It also had excellent humidity control. I agree that systems with multi-speed (or two-stage) compressors is the way to go. Our Mitsubishi mini-split for the lanai has a continuously variable speed compressor that runs between 25-100% of nominal capacity.
