The best way to keep your house cool in the summer without breaking the bank is to install ceiling fans. Ceiling fans can be used to circulate air throughout your home, which helps keep it cooler and more comfortable. Additionally, you can open windows on hot days or use an oscillating fan to help move air around. You can also consider investing in a window air conditioning unit, as these are generally much more energy efficient than central air systems.
