JEAAir conditioning and heating systems consume about 40 – 60% of all the electricity customers use, according to JEA. Set your thermostat at 78°F in summer, 5° to 10° higher when you leave the house.
Change your heating and cooling system air filter every month. A dirty air filter makes your system work harder, which uses more energy. Run ceiling or table fans when possible, instead of lowering the air conditioning thermostat. Fans can help make it feel 2 to 3 degrees cooler. Turn them off when you leave the room.Avoid going in and out of the home repeatedly to keep cool air in and hot air out.Try grilling outside, using the microwave or cooking with a Crockpot or InstantPot instead of the stove or oven. Small appliances typically use less energy and keep the kitchen cool.
