Florida summers are no joke. With high humidity and soaring temperatures, keeping your home cool and your energy bills in check can feel like a full-time job. One of the smartest ways to strike that balance? Adjusting your thermostat settings for maximum comfort and efficiency. If you’re searching for the best way to program your thermostat in Jacksonville, our team at A/C Designs has your back.
Best Thermostat Settings for Florida Summer Comfort
For most homes, the U.S. Department of Energy recommends setting your thermostat to 78°F when you’re home during the summer months. This may seem a bit warm, but it’s a sweet spot that balances comfort and energy savings—especially if you have ceiling fans to help circulate the air.
When you’re away from home, bump the temperature up to around 85°F. This reduces strain on your HVAC system without letting the house become unbearably hot. Smart thermostats make this adjustment easy by allowing you to set schedules and control your system remotely.
Use a Programmable or Smart Thermostat to Save Energy
If you’re still adjusting your thermostat manually, you’re missing out on a major opportunity for both comfort and savings. Programmable and smart thermostats let you automate your cooling based on your daily routine. Heading out to work? Your thermostat will raise the temperature to save energy. Coming home at 6 PM? It cools your home in advance, so you’re walking into comfort, not a sauna.
Some smart thermostats even learn your preferences over time, automatically adjusting without you having to lift a finger. That’s the kind of summer convenience we’re all about here at A/C Designs.
Control Indoor Humidity to Improve Cooling Efficiency
In Florida, humidity is just as important as temperature. High humidity can make your home feel hotter than it is, even when your thermostat is set correctly. To help your system perform better, consider running your A/C in “auto” mode instead of “on.” This gives the unit a chance to remove more moisture from the air, improving comfort and reducing energy waste.
If you still feel sticky indoors, a whole-home dehumidifier might be worth considering. Our team can help you determine the best solution for your space.
Schedule Routine AC Maintenance for Summer Efficiency
The best thermostat settings won’t do much if your system isn’t in peak condition. Dirty filters, blocked vents, and low refrigerant can all reduce your A/C’s efficiency, no matter where the dial is set. We recommend scheduling seasonal maintenance to keep things running smoothly—and to prevent unexpected breakdowns during peak summer heat.
Pro Tip: Change your air filters every 1-2 months during high-use seasons. It’s a small task with big impact.

Frequently Asked Questions
Question: What is the best thermostat setting for Florida summers?
Answer: A good starting point is 78°F when you are home, which helps balance comfort and energy efficiency. Florida’s humidity can make the air feel warmer, so ceiling fans, clean filters, and steady airflow can help your home feel more comfortable without lowering the thermostat too much.
Question: Should I turn my thermostat up when I leave the house?
Answer: Yes, raising the thermostat a few degrees while you are away can reduce cooling costs without making your AC work too hard. A programmable or smart thermostat can make this easier by adjusting the temperature automatically before you return home.
Question: Is it bad to set my thermostat very low in the summer?
Answer: Setting the thermostat too low can make your air conditioner run longer, use more energy, and add extra strain to the system. It may also make it harder to manage humidity if the system is not operating properly. Choosing a steady, efficient setting is usually better than constantly making large temperature changes.
Question: What thermostat setting is best for sleeping in Florida?
Answer: The best sleeping temperature depends on your comfort, but many homeowners prefer a slightly cooler setting at night. To save energy, try making small adjustments instead of dropping the temperature dramatically. Ceiling fans and proper airflow can also help bedrooms feel cooler.
Question: Can a smart thermostat help lower summer cooling bills?
Answer: Yes, a smart thermostat can help manage cooling schedules, reduce unnecessary runtime, and keep your home comfortable more efficiently. It can automatically adjust settings based on your routine, which is especially helpful during long Florida summers.
