Use Your Windows to Gain Cool Air and Keep Out Heat

• Take advantage of natural ventilation by turning off your cooling system and opening your windows while sleeping. When you wake in the morning, shut the windows and blinds to shut in the cool air.
  
  
• Install window coverings to prevent heat gain through your windows. Certain window treatments and coverings, including awnings, blinds, shades and shutters can actually improve energy efficiency. High-reflectivity window films and mesh window screens can help block summer heat gain. However, it's important to caulk and weatherstrip around windows to reduce air leakage.
  
  

Operate Your Thermostat Efficiently

• Set your thermostat as high as comfortably possible in the summer. You will notice that the smaller the difference is between the indoor and outdoor temperatures, the lower your overall cooling bill.
  
  
• Keep your house warmer than normal when you are not at home. By using a programmable thermostat you can save approximately 10% a year on heating and cooling bills. Simply turning your thermostat back 10ƒ-15ƒ for the eight hours you are asleep, will generate significant savings.
  
  
• Avoid setting your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and unnecessary expense.
