Refrigerators use more energy than any other appliance, because this is the case, consumers should shop wisely when buying a refrigerator. Look for trustworthy brands and research the model to make sure it has an energy efficiency seal. It will payoff if you keep up on the maintenance of older fridges, this includes regular cleaning and replacing coils, replacing seals and coolant. Replacing coolant can save large amounts of energy because it brings the refrigerators temperature down to the “cold” area. Repair and regular maintenance may require a repairperson, but it will be well worth the money in the long run.
Stoves and Ovens
An oven or range should always be installed away from the refrigerator because the heat will make the fridge have to work harder to stay cool. There should always be a range hood that properly ventilates to the outside of the house. Do not use a hood that recirculates and filters fumes because it using more energy and is not always safe especially with gas ranges.
When using a fan you need to make sure it is the proper size because fans that are too large waste energy and can cause combustion gases to back-draft into the house. Large downdraft ventilation fans tend to have this problem, so make-up air ducts are available for these models; check with your supplier.
Air Conditioners
The most important aspect of keeping your air conditioner energy efficient is the proper repair and maintenance. This is works well for older models as well. Regular cleaning and filter replacement keeps the wear and tear on the motor to a minimum thus lowering the electricity consumption, which saves you money.
