Florida temperatures in summer can be hot and humid, so it’s important to keep your home cool and comfortable with the right air conditioner setting. You might be wondering what should I keep my AC at in Summer in Florida to find a balance between comfort and keeping energy costs low? In this blog post, we will discuss the best temperature to keep your AC at in the summertime in SWFL, as well as easy ways to stay cool and comfortable without breaking the bank.

What Should I Keep My AC at in Summer in Florida?

When it comes to setting the perfect cooling system temperature for Florida summers, there are a few recommended guidelines to follow. The ideal temperature range and a good rule of thumb is to keep your thermostat between 72 and 78 degrees Fahrenheit. This range allows for a comfortable indoor environment without putting too much strain on your AC system or skyrocketing your energy bills. 

However, it’s important to note that everyone has different preferences and everyone will find their own best thermostat setting, so feel free to adjust within this range to find your sweet spot. Also consider using a programmable thermostat to automatically adjust the temperature when you’re not at home, saving energy and money. Experiment with different temperatures to find what works best for you and your home. For maximum efficiency, try to slowly increase your tolerance to a higher temperature. If you stay between 72 and 78, it will still be considerably cooler inside your home than the hot air outside during a South Florida summer. This range will also keep your humidity levels indoors down. 

How to Maintain Energy Efficiency While Keeping Cool

Keeping cool during the hot Florida summers doesn’t mean you have to sacrifice energy efficiency. Here are some tips to help you maintain both. 

  • Make sure your home is well insulated to prevent cool air from escaping during warmer weather. Seal any cracks or gaps in windows and doors, and consider adding insulation to your attic and walls. This will reduce the workload of your HVAC unit.
  • Use ceiling fans to help circulate the cool air, which can make your AC more effective and keep your home at the right temperature. 
  • Remember to adjust your thermostat settings when you’re not at home to avoid unnecessary cooling. Use a smart thermostat so you can program the thermostat to adjust to higher temperatures when you’re away and back to a lower temperature, and more comfortable temperature before you return home.
  • Keep your air conditioning unit well-maintained by regularly cleaning or replacing filters and scheduling professional tune-ups. 

Additional Tips for Staying Comfortable During the Summer Months

As the temperatures rise in Florida during the summer months, staying cool and comfortable becomes a top priority. Along with setting the right AC temperature, there are a few additional tips that can help you beat the heat and stay comfortable all summer long. 

  • Try to minimize the use of heat-generating appliances during the hottest parts of the day to keep the temperature of your home comfortable. This includes using the oven or stove, which can increase the temperature in your home. Instead, opt for grilling outside or using a slow cooker. 
  • Consider using window treatments to block out the sun’s rays during the hottest parts of the day. This can help keep your home cooler and reduce the workload on your AC system, as well as the energy usage. Less energy usage always equals a lower electric bill. 
  • Try to stay hydrated by drinking plenty of water throughout the day. This can help regulate your body temperature and keep you feeling refreshed in high humidity and heat.


Finding the perfect AC temperature for your Florida summer is crucial for staying cool and comfortable while also being mindful of your energy bills. The recommended temperature range of 72 to 78 degrees Fahrenheit provides a comfortable environment without straining your AC system or increasing your energy costs. Remember to experiment within this range to find your personal sweet spot. 

Maintaining energy efficiency is also important, so be sure to implement things like closing your curtains to block direct sunlight during the hottest part of the day. By following these guidelines and being mindful of your AC temperature, you can enjoy a cool and comfortable summer in Florida without breaking the bank during the hottest months of the year.  Contact us with any questions!
