With much of the U.S. grappling with intense summer heat, air conditioners are working overtime to maintain comfort and safety at home. But what’s the optimal temperature setting during a heat wave, and how can you effectively cool your living space?

The Department of Energy recommends setting your AC to a temperature that feels comfortable while also managing humidity. They emphasize that minimizing the difference between indoor and outdoor temperatures helps reduce overall cooling costs.

Recommended AC Settings

Energy Star, an initiative by the Environmental Protection Agency promoting energy efficiency, suggests setting your air conditioner to 78 degrees Fahrenheit during waking hours for both comfort and efficiency.

However, a 2021 Consumer Reports survey found that most people with central AC set their thermostats to a median of 72 degrees—much cooler than the energy-saving guideline. None of the respondents chose a setting above 76 degrees.

Adjustments Throughout the Day

For energy savings, Energy Star advises raising the thermostat by 4 degrees while sleeping and 7 degrees when away from home. Using a programmable thermostat can automate these adjustments, ensuring energy efficiency without compromising comfort.

Managing AC Use When Away

Turning up the temperature while you’re at work or on vacation can save money compared to keeping your home constantly cool. However, completely shutting off the AC system may lead to higher costs as it works harder to cool down upon your return. For shorter absences, adjusting the temperature slightly can minimize the impact on your utility bills.

Tips for Cooling Efficiency

To further improve cooling efficiency and control costs:

Window Management: Use curtains to block out heat and sunlight.

Appliance Usage: Limit the use of heat-producing appliances.

Weather Stripping: Ensure doors and windows are properly sealed.

Ceiling Fans: Use them to circulate air, though they don’t lower room temperature directly; they create a cooling effect by enhancing evaporation.

Conclusion

As climate change increases the frequency of hot days, the demand for air conditioning rises. Following these recommendations and adopting energy-efficient practices can help manage your home’s temperature during a heat wave while keeping utility bills in check.
