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.
