The duct work is insulated. Could it be insulated more? Sure but it is insulated to probably R-6. I believe you will find that most air handlers in Villages homes are single speed (are programmed for a single speed from several possible options).

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.
