Absolutely. Opening your windows for fresh air (and turning off your air conditioner) is a common one. However, if it’s too hot outside to open windows, consider turning down the AC and switching your ceiling fans to rotate counterclockwise to keep cool air flowing. You can also schedule AC maintenance to improve energy efficiency, close curtains during the day to keep out the warm sunlight, and install a programmable thermostat to schedule temperature changes and minimize energy usage.
