Play it cool with these simple tips.

General tips:

  • Plant a deciduous shade tree near your home to control the amount of heat that reaches your house.
  • Increase your attic insulation if the joists are showing. Recommended level: R-38 or 10-16 inches blown.
  • Have your HVAC systems serviced or tuned-up annually to maximize efficiency and comfort.
  • Seal leaking ductwork throughout your home. Approximately 20% of air moving through duct systems is lost to leaks.
  • Check your HVAC filter every month, especially during the summer and winter. A dirty filter can shorten the life of the system.


  • Install a programmable thermostat; set it higher when you are away.
  • Setting your air conditioner just five degrees higher can save 20% on cooling costs.
  • Install ceiling fans to circulate cool air throughout the house.
  • Maintain consistent temperatures.

Windows and vents:

  • Seal and weatherstrip around doors and windows. About 10-25% of energy used to cool homes escapes via leaks.
  • Shade your windows with light-colored shades to reflect heat.
  • Close draperies and shades on south-facing windows to block sunlight and heat during the day.
  • Install awnings on windows that get excessive sun in the late afternoon.
  • Move furnishings away from floor or return air vents.
