I have seen larger commercial A/C systems that will run 2 or 3 compreasors. It keeps the machine from short cycling, but still allows it to cool even during the highest demand.

With a compressor ran off an inverter coupled with an electronically controlled expansion valve all you need is 1 compressor.
For my house I have a 2 ton inverter split for 500 to 700 square feet, which is way oversized. It works great. No short cycling and we can fire up the stove during the day and not heat up the house.
