This is a common problem and difficult to solve. The basic issue is that most homes are single zoned with the thermostat in a common area (that tends to stay warmer/cooler than the periphery of the house.). If you have a remote bedroom, like we do, with two outside walls plus several windows (with a low insulation rating), it's temperature can fall/rise faster than the common area where the thermostat is located. As the sun rises, one side of the house will be warmed faster than the other side of the house. The remote bedroom can only be heated/cooled when the system is running and that is controlled by the temperature changes in the common area where the thermostat is located. Our remote bedroom is fine when the system is running but it cools/warms faster than the rest of the house as soon as the system shuts off. If you want truly uniform temperatures throughout the house you need a multiple zone system. A properly sized system, and a system with a multi-speed compressor, will tend to have longer runtimes which will help to maintain more uniform temperatures.
However, by Florida code, a so-called Manual J heat load/heat loss calculation was done for your house. The results are actually on-line. One of the results of this calculation is a specification of the cubic feet per minute of airflow that the duct system must be designed to provide to each room. It may be worthwhile to have the airflow measured to each room to make sure it matches the requirements of the Manual J calculation. There are people who can do this. It is possible that the contractor did not design and install a duct system that matches the Manual J requirement. In that case, a call to The Villages Warranty Dept. would be in order as you have a 10-year warranty on systems in your house. However, even if the duct system is spot on correct, the issue with a single zone system that I discussed above will result in some temperature unevenness across rooms.

For some reason my bedroom is several degrees warmer than the rest of my house. With the colder weather we have been experience I haven't minded it so much. However, now that we are getting warmer days intermittently mixed in it is becoming extra apparent the difference in temperature.
I've had someone take a look at it and claim that I need an entire new duct system??
I was hoping someone can help me before I spend thousands of dollars to fix one room.
Best,
