Best AC Temperature for Summer

What is the Best AC Temperature for Summer?

Finding the ideal AC temperature for summer is essential for maintaining a comfortable home environment while keeping energy costs low. Setting the best AC temperature involves balancing cool air with energy efficiency, and understanding how different factors such as indoor air quality, humidity, and outdoor temperature affect your air conditioning system. In this post, we’ll explore the best practices for setting your air conditioner during the summer months to ensure a comfortable and energy-saving experience.

Ideal AC Temperature for Comfort and Savings

According to Energy Star, the recommended thermostat setting for optimal comfort and energy efficiency during the summer is 78 degrees Fahrenheit. This temperature setting provides a comfortable indoor environment while minimizing energy consumption and reducing your energy bill. Using ceiling fans in conjunction with your air conditioning unit can help circulate cool air more effectively, allowing you to maintain a higher temperature setting without sacrificing comfort. Smart thermostats and programmable thermostats can automatically adjust the temperature based on your schedule, further enhancing energy savings.

The Role of Smart Thermostats in Energy Efficiency

Smart thermostats and programmable thermostats are valuable tools for optimizing your AC temperature for summer. These devices allow you to set schedules that automatically adjust the temperature when you’re not home, reducing energy consumption without compromising comfort. For instance, you can set the thermostat to a higher temperature during the day when the house is empty and lower it to the ideal temperature before you return home. Smart thermostats can also learn your preferences and make adjustments based on your daily routine, helping you save on energy costs while maintaining a comfortable indoor temperature.

Additional Tips for Maintaining a Comfortable Home

In addition to setting the ideal AC temperature, there are other ways to keep your home cool and energy-efficient during the summer. Regular AC maintenance, such as cleaning or replacing air filters, ensures your air conditioning system runs efficiently and maintains good indoor air quality. Using ceiling fans to circulate cool air can help maintain a comfortable temperature while allowing you to set the thermostat at a higher temperature. Additionally, keeping blinds and curtains closed during the hottest parts of the day can reduce heat gain and lower the workload on your AC unit.

Balancing Comfort and Energy Savings

While 78 degrees Fahrenheit is often cited as the best AC temperature for summer, individual preferences and specific household needs may vary. Some may find a slightly lower temperature more comfortable, especially during particularly hot days. However, each degree below 78 degrees can increase energy consumption by approximately 6-8%, leading to higher energy bills. Finding a balance between a comfortable temperature and energy efficiency is key. Monitoring your energy usage and making small adjustments can help you find the optimal setting for your home.


Setting the best AC temperature for summer is crucial for maintaining comfort and energy efficiency in your home. A thermostat setting of 78 degrees Fahrenheit is generally recommended for balancing cool air and energy savings. Utilizing smart thermostats, ceiling fans, and regular AC maintenance can enhance your HVAC Festus Mo system’s performance and reduce energy costs. By following these tips, you can enjoy a comfortable and energy-efficient home throughout the summer months, keeping your air conditioning system running smoothly while minimizing your energy bill.
