• Set your thermostat on the highest comfortable setting. We recommend 78 degrees or higher. Remember, every degree above 78 will save you about 4% in cooling costs. If you’re not going to be home for an extended period, raise your thermostat to 85-88 degrees. 
• Clean or change your filters monthly to keep your system running at peak performance.
• Use a ceiling fan or portable fan to supplement your air conditioning. A fan can make you feel three to four degrees cooler so you can set your thermostat a few degrees higher and save on cooling costs. Use in occupied rooms since fans cool people, not rooms.
• Switch your central air conditioning to "auto" for better cooling and humidity control bill versus keeping the system switched "on" continuously.
• Unplug outside refrigerator/freezer if not in use or if items will fit in your indoor refrigerator/freezer.
