Did you know that your refrigerator accounts for 15% of your home’s total power usage? If your refrigerator has clogged, dirty coils, it requires 25% more energy to run than if they were clean! Dust, dirt and pet hair can accumulate on the coils (which are designed to remove heat from the refrigerator) causing them to run longer and harder.
That’s why at least twice a year, you should vacuum the refrigerator coils (beneath the unit for newer models or at the back of your refrigerator for older models) with a brush attachment. Refer to the owner’s manual to locate the coils and access them safely (be sure to shut off the electricity or unplug the unit first!) Use a vacuum with a brush attachment to loosen and vacuum up the accumulated dust. If you have a longer brush to gently brush the dust from behind the coils, that would help as well. It’s estimated that dirty coils can increase energy use by 6%; the amount of savings will vary, but it can be anywhere from $15-$100 per year!
