Install set-up (set-back) digital thermostats on your A/C system or heat pump. Every degree of set "up" for air conditioning may save up to 6% on central A/C electric usage. These devices can also "turn off" A/C when you are not home. (Be sure to select the appropriate model; professional installation is recommended.)

Close windows and doors during the hottest parts of the day, and when outdoor conditions are humid. Humidity can build up in home furnishings and may cause your A/C to run longer.

Close draperies and window shades on sunny warm days, particularly on south and western facing windows.

Reduce oven, stove, indoor lights, and TV use since appliances release considerable by-product heat indoors resulting from electrical use.

Accentuate natural lighting in your home, this will reduce the need for lighting. Use "solar tube" skylights where spaces have no windows.

Install ceiling fans in your most frequently occupied rooms, such as family rooms and bedrooms. These fans can make 80 degrees seem like 75 degrees.

When outdoor conditions are mild -- open your windows in all rooms of the home for natural ventilation. Screens are recommended!

Choose energy-efficient windows for replacements, that are rated by the "NFRC," or have and equivalent energy performance warrantee from the manufacturer or builder. (NFRC - "National Fenestration Rating Council")

Plant drought tolerant shade trees around your home, but remember to provide good Winter-time "solar" access to south-facing windows.

Select the lightest colors when painting your home, or putting on a new roof. Be sure to promote light surfaces to your home owners association to make sure they are acceptable in your neighborhood.
