What Temperature to Set Your Air Conditioner to in Summer


As summer temperatures rise, maintaining a comfortable and energy-efficient home becomes a top priority. A key factor in achieving this balance is knowing what temperature to set your air conditioner to in summer. Striking the right balance can help you stay cool, save on energy bills, and reduce your environmental footprint. In this guide, we’ll explore the optimal settings for your air conditioner during the hottest months of the year.

Understanding the Optimal Temperature

The U.S. Department of Energy recommends setting your air conditioner to 78°F when you’re at home and need cooling. This temperature strikes a balance between comfort and energy efficiency. However, preferences can vary, and factors such as humidity, personal comfort, and activity levels can influence the ideal setting.

Facts to Consider

Personal Comfort

Everyone’s comfort level is different. Some might find 78°F comfortable, while others may prefer a cooler setting. It’s important to adjust the temperature based on your personal comfort and the needs of your household.

Humidity Levels

High humidity can make you feel warmer than the actual temperature. If you live in a humid area, consider using a dehumidifier along with your air conditioner to maintain a comfortable indoor environment.

Activity Levels

If you are engaging in physical activities or cooking, you might need a cooler setting to stay comfortable. Conversely, if you’re sitting or sleeping, a slightly higher temperature might be sufficient.

Energy Efficiency

Setting your thermostat a few degrees higher when you’re not at home or during the night can lead to significant energy savings. Programmable or smart thermostats can help automate these adjustments, ensuring your home remains comfortable while optimizing energy use.

Tips for Maintaining Comfort and Efficiency

Use Fans

Ceiling and portable fans can help circulate cool air throughout your home, allowing you to set your thermostat a few degrees higher without sacrificing comfort.

Close Blinds and Curtains

Blocking out direct sunlight can keep your home cooler and reduce the load on your air conditioner.

Maintain Your AC Unit

Regular maintenance, such as cleaning or replacing filters, can improve your air conditioner’s efficiency and longevity. A well-maintained unit cools more effectively, allowing you to set the temperature higher without losing comfort.

Seal Leaks

Ensure that windows and doors are properly sealed to prevent cool air from escaping and warm air from entering. This can help your air conditioner work more efficiently and maintain a consistent temperature.

Benefits of Setting the Right Temperature

  • Energy Savings: According to the Department of Energy, raising your thermostat by 7-10 degrees for 8 hours a day can save up to 10% on your annual cooling costs.
  • Environmental Impact: Using less energy reduces your carbon footprint, contributing to environmental conservation efforts.
  • Extended AC Lifespan: Running your air conditioner at a moderate temperature reduces wear and tear, potentially extending the lifespan of your unit and reducing the need for repairs.

Determining what temperature to set your air conditioner to in summer is crucial for maintaining comfort and optimizing energy efficiency. While 78°F is a good starting point, personal preferences and environmental factors play a significant role. By considering your comfort, activity levels, and using strategies like fans and dehumidifiers, you can find the perfect balance for your home.
