Unfortunately, The Villages doesn't go this route but you can when the original system needs replacing. We had a two speed Carrier Infinity system in a previous house and it worked great. We currently have a Mitsubishi mini-split for the lanai and it can ramp anywhere from 25 to 100% of the nominal capacity. Works great.

I would recommend not putting in a variable speed compressor (variable speed fan is probably ok), unless you have insulated duct work ... which I don't believe The Village's construction has.
Variable speed compressors are more expensive to buy, but do save energy. The "pay back" is likely going to about 5-7 years.
They do much better job at maintaining a constant temperature, probably +/- 1 degree, rather than 3. A 2 Stage might be reasonable compromise.
Here's a link that will tell you more about it.
