Use kitchen, bath, and other ventilating fans wisely. Turn these fans off as soon as they are no longer needed. In about 1 hour, these fans can pull out a house-full of warmed or cooled air.
Don't keep your refrigerator or freezer too cold. Recommended temperatures are 37° to 40°F for the fresh food compartment of the refrigerator and 5°F for the freezer section. If you have a separate freezer for long-term storage, it should be kept at 0°F.
When using a clothes dryer, separate your clothes and dry similar types of clothes together. Lightweight synthetics, for example, dry much more quickly than bath towels and natural fiber clothes.
When shopping for a dishwasher, look for features that will reduce water use, such as booster heaters and smart controls. Ask how many gallons of water the dishwasher uses during different cycles. Dishwashers that use the least amount of water will cost the least to operate.
To check refrigerator temperature, place an appliance thermometer in a glass of water in the center of the refrigerator. Read it after 24 hours. To check the freezer temperature, place a thermometer between frozen packages. Read it after 24 hours.
Dry two or more loads of clothes in a row, taking advantage of the dryer's retained heat.
When shopping for a clothes washer, look for the following design features that help clothes washers cut water usage: water level controls, "suds-saver" features, spin cycle adjustment, and large capacity. For double the efficiency, buy an Energy Star unit.
Regularly defrost manual-defrost refrigerators and freezers; frost buildup increases the amount of energy needed to keep the motor running. Don't allow frost to build up more than one-quarter of an inch.
Clean the lint filter in the clothes dryer after every load to improve air circulation. Remember to regularly clean the lint from vent hoods, too.
Replacing the seals on your refrigerator is not hard and can make a big improvement in the aplliances efficiency (and appearance). Replacement seals are often available at many home goods store and through the maker of the unit. One tip for using these replacement seals is to warm them before installing, this removes the crimps that often occur from their packaging. A few minutes in the clothes dryer should do the trick.
