<human>: What's the best way to keep my house cool in the summer without turning on the air conditioning?
<bot>: The best way to keep your house cool in the summer without turning on the air conditioning is to open windows during the day and close them at night, or use window fans. You can also try setting up a fan in each room of your home, as well as using ceiling fans. Additionally, you could install an evaporative cooler in each room that has a window, which will help cool the air inside your home naturally.
