What Should I Set My Thermostat to in Florida?
By HVAC.com•March 26, 2025
Finding the Perfect Temperature for Comfort and Efficiency
Florida is known for its sunshine, beautiful beaches, and, of course, its heat. Summers can be brutal, with temperatures soaring into the 90s or higher with humidity levels that make it feel even hotter.
With your air conditioner working overtime to keep your home cool, setting your thermostat to the right temperature is key – not only for comfort but also for energy efficiency, lower utility bills, and protecting your HVAC system from unnecessary strain and wear.
Why Florida’s Climate Affects Thermostat Settings
Unlike other parts of the country, Florida’s heat isn’t just about high temperatures; it’s the humidity that makes the biggest difference. Humid air holds more moisture, making it feel warmer than the actual temperature on the thermostat. Because of this, many Florida homeowners think they need to crank the AC down to stay comfortable. However, setting your thermostat too low can overwork your system, leading to higher energy bills and potential wear and tear on your unit.
Compared to cooler, drier regions, Floridians should aim to keep their thermostats set a little higher in the summer to reduce strain on the system while still maintaining a comfortable indoor environment.

Best Temperature While at Home
For optimal comfort and efficiency, the U.S. Department of Energy recommends setting your thermostat to 78°F while you’re home in the summer. This might seem warm if you’re used to cooler settings, but when paired with ceiling fans and proper humidity control, it can keep your home comfortable without overworking your AC. If 78°F feels too warm, try gradually increasing the temperature by one degree at a time to let your body adjust.
Best Temperature While Away
If you’re leaving for work or heading out for the day, raising your thermostat by a few degrees can help you save on energy costs. A good rule of thumb is to set it between 80-82°F when you’re not home in the summer. This prevents your AC from running unnecessarily while still keeping indoor temperatures at a manageable level.
If you’re going on vacation, setting your thermostat even higher – around 82-84°F – can prevent excessive cooling costs while protecting your home from extreme heat buildup. A programmable or smart thermostat can make this even easier by automatically adjusting temperatures based on your schedule.
The Importance of AC Maintenance in Florida
Because Florida’s climate puts extra stress on HVAC systems, regular maintenance is key to keep your air conditioner running efficiently. Routine tune-ups help prevent breakdowns, extend your system’s lifespan, and ensure it’s operating at peak performance.
What’s Included in AC Maintenance?
During a professional maintenance visit, an HVAC technician will:
- Inspect and clean coils for better efficiency
- Check refrigerant levels and look for leaks
- Lubricate moving parts to prevent wear
- Test the thermostat for accuracy
- Clear drain lines to prevent mold and clogs
- Replace or clean air filters for better airflow
When to Schedule Maintenance
The best time to schedule AC maintenance is in the spring before the peak summer heat. This ensures your system is in top shape before it has to work its hardest. Many homeowners also schedule a second check-up in the fall to prepare for winter and keep their system running smoothly year-round.
