What Temperature Should I Set My Air Conditioner to in Summer?

As the summer heat starts to rise, keeping your home comfortable becomes a top priority. One common question homeowners ask is, “What temperature should I set my air conditioner to in the summer?” Finding the perfect balance between comfort and energy efficiency is crucial. Here’s a guide to help you set your thermostat for the summer months.

The Recommended Temperature

According to the U.S. Department of Energy, the ideal temperature setting for your air conditioner during the summer is 78°F (25°C) when you are at home and awake. This temperature strikes a balance between keeping your home cool and conserving energy.

When You’re Away

When you’re not at home, it’s recommended to increase the temperature by 7-10 degrees. Setting your thermostat to around 85°F (29°C) while you’re away can help you save on energy costs without sacrificing comfort. Modern programmable and smart thermostats make it easy to adjust the temperature settings based on your schedule.

At Night

For a comfortable night’s sleep, consider setting your air conditioner to a slightly cooler temperature, around 72-74°F (22-23°C). However, this can vary based on personal preference. Using a programmable thermostat allows you to set different temperatures for different times of the day, ensuring you always have the perfect sleeping environment.

Tips for Maximizing Comfort and Efficiency

  1. Use Ceiling Fans: Ceiling fans can help circulate cool air throughout your home, allowing you to set your thermostat a few degrees higher without sacrificing comfort.
  2. Close Blinds and Curtains: Keeping blinds and curtains closed during the day can reduce the amount of heat entering your home, making it easier for your air conditioner to maintain a cool temperature.
  3. Avoid Heat-Generating Activities: Try to limit activities that generate heat, such as cooking or using the oven, during the hottest parts of the day.
  4. Maintain Your HVAC System: Regular maintenance, such as cleaning or replacing air filters and scheduling professional inspections, can improve your system’s efficiency and performance.
  5. Use a Programmable Thermostat: Investing in a programmable or smart thermostat allows you to set different temperatures for different times of the day, optimizing comfort and energy savings.

Benefits of Setting the Right Temperature

Setting your air conditioner to the optimal temperature can provide several benefits, including:

  • Energy Savings: Maintaining a higher temperature when you’re away or asleep can significantly reduce your energy bills.
  • Increased Comfort: Keeping your home at a consistent and comfortable temperature can improve your overall well-being during the hot summer months.
  • Extended HVAC Lifespan: Properly managing your air conditioner’s usage can reduce wear and tear, extending the life of your system.


Finding the right temperature setting for your air conditioner in the summer can help you stay cool and comfortable while saving on energy costs. By following these guidelines and using programmable thermostats, you can achieve the perfect balance between comfort and efficiency.
