The greatest return on your money is soffit and peak roof air exchange and attic insulation. Think of the interior of your home as a sealed unit and your attic is a tremendous heat source. Typically, I recommend the homeowners rent the machine at Home Depot and blow their own additional insulation and I’m sure their services The Villages.
HUD recommend a 40 to 50 R-value for the attic which is 20 to 25 inches at the time of installation. The second step which most people neglect is the airflow from the soffits to the peaks of your roof (gable vents &/or vents). Just adding gable vents &/or power vents It’s not enough as you can only extract as much air to pump in. Therefore, you need to add additional soffit vents. Which I can tell you from 30 years experience I’ve never seen anything but custom energy, energy minded builders ever put enough soffit vents.

But what about hurricanes & wind-driven water? Better ask your insurance company before increasing soffitt vents in TV due to increased damage risk. Soffit vents are a frequent point of wind-driven water intrusion causing extensive water damage from hurricanes. Wind-driven water is one of the main threats to TV from hurricanes, besides potential tornadoes spawned.
