What’s the Best Temperature to Set Your Thermostat in Naples, Florida During the Summer?

When the summer sun is blazing over Naples, Florida, your air conditioner becomes your best friend. But as energy bills rise and comfort becomes a priority, many homeowners are left wondering: What’s the optimal temperature to set the thermostat? The answer lies in finding a balance between comfort, energy savings, and the unique demands of Florida’s hot, humid climate.

The Magic Number: 78°F (When You’re Home)

According to the U.S. Department of Energy, 78°F is the ideal temperature to keep your home comfortable while maximizing energy efficiency during the summer. At this setting, your AC isn’t overworked, yet your home remains cool and livable—even on those scorching Gulf Coast afternoons.

Adjusting for Comfort and Savings

If 78°F feels a little too warm for your liking, you can still stay comfortable without breaking the bank. Here are a few tips:

  • Use ceiling fans to make the air feel cooler. Fans don’t lower the temperature but can make 78°F feel more like 74°F.
  • Close blinds and curtains during the hottest parts of the day to block out heat from the sun.
  • Avoid using heat-producing appliances (like ovens) in the middle of the day.

When You’re Away

When you leave your home for work or errands, set your thermostat to 85°F. This prevents your home from becoming an oven but still saves energy. If you have pets, adjust accordingly to ensure their comfort.

Smart Thermostats: Your Summer MVP

Consider upgrading to a smart thermostat. These devices learn your schedule and preferences, adjusting your home’s temperature automatically. Some models even factor in local weather and help reduce your energy consumption without sacrificing comfort.
