As peak summer temperatures hit Texas, more and more people become reliant on air conditioning systems. Once a luxury, air conditioning is now a necessity during the summer months.

According to the U.S. Energy Information Administration, 90% of American households used air conditioning as of 2020. Texas, the state that consumes the most energy, accounts for about one-seventh of the nation's total energy consumption and ranks sixth in per capita energy use.

With summer temperatures consistently exceeding 90 degrees in densely populated areas, the demand for cooling is substantial. The state, due to its large population, leads the nation in total residential energy consumption.

For people looking to stay cool while being mindful of their energy bill this summer, a question arises: What is the best temperature at which to set your thermostat during the scorching summer months?

What is the recommended temperature?

The U.S. Department of Energy has said 78 degrees is the ideal temperature for the summer, providing the most savings without too much discomfort. Each degree lower increases your energy use by 6% to 8%.

Should I turn off my air conditioner if I leave for work or vacation?

Texas Energy recommends setting your thermostat at 85 while away to save up to 10% on your yearly costs.

However, the duration of your absence and personal preferences will determine whether this is worthwhile. Depending on outside temperatures and the size of your home, it might take some time for conditions to become comfortable again.

How can I conserve energy in the summer months?

The City of Austin's Office of Sustainability recommends these warm-weather tips to help you stay cool and lower your energy expenses:

  • Block out the sun: Close blinds on the south and west sides of your home during the day to prevent about 40% of summer heat from entering through windows.

  • Cook cool: Avoid using the oven to keep your house cooler. Opt for microwave cooking, grill outdoors in the shade, or prepare meals that don't require cooking.

  • Upgrade to a smart thermostat: Install a thermostat with Wi-Fi to control your AC remotely and possibly receive incentives.

  • Power down electronics: Turn off lights in empty rooms and limit use of electronics. Even in standby mode, devices such as computers and TVs emit heat and consume energy.

  • Enhance air circulation: Use ceiling fans set to rotate counterclockwise in summer for optimal cooling. Turn off fans when not in use or try placing a pan of ice in front of a fan for added cooling.

  • Shade strategically: Plant trees or tall perennials such as sunflowers and native plants to provide natural shade over time. Plant trees from October to March in Central Texas for best results.
