When the summer heat rolls in, finding the perfect balance between comfort and energy savings can feel like a challenge. But don’t sweat it, experts have weighed in on the ideal summer thermostat setting to keep your home cool without breaking the bank.
The Magic Number: 78 Degrees
According to the U.S. Department of Energy, the best summer thermostat setting for most homes is 78°F. This temperature strikes a balance between comfort and energy efficiency. For every degree above 72°F, you can save up to 3% on cooling costs. So, setting your thermostat to 78°F can lead to noticeable savings on your energy bill.
If 78°F feels a bit warm, consider using ceiling fans to circulate air. When set to spin counterclockwise, ceiling fans create a cooling breeze, making the room feel up to 4°F cooler. This allows you to raise the thermostat a few degrees without sacrificing comfort.
Adjusting When You’re Away
When you’re not home, there’s no need to keep the thermostat at 78°F. Experts recommend increasing the temperature by 7-10°F while you’re away. This simple adjustment can save up to 10% on your energy bill. Smart thermostats make this even easier by allowing you to schedule temperature changes or adjust settings remotely.
Why Humidity Matters
Humidity plays a significant role in how comfortable your home feels. High humidity can make 78°F feel much warmer. If you live in a humid area, consider investing in a dehumidifier or an HVAC system with built-in humidity control. Lowering the humidity in your home can make it feel cooler, even at higher thermostat settings.
Seasonal Maintenance for Efficiency
Your air conditioning system works hard during the summer, so regular maintenance is essential. Dirty filters, leaky ducts, and poor insulation can all reduce efficiency, making it harder to maintain your desired temperature. Schedule a seasonal tune-up to ensure your system is running at peak performance.

Make Your Home Naturally Cooler
Simple changes can help keep your home cooler without overworking your AC:
- Close blinds and curtains during the day to block out heat.
- Use energy-efficient appliances during cooler parts of the day.
- Seal windows and doors to prevent cool air from escaping.
