Here's Alec from St Mary School vacuuming away the dust from the backside of his home's refrigerator with a little help from an adult. Accumulated dust that collects on fridge coils reduces the coils' ability to dissipate heat. That means your fridge's compressor must work harder to maintain a cooler inside temperature. Some fridge coils are located in the back. Some are located in the front below the fridge door(s) behind a small grill. And some are at the top of the fridge behind a panel. Spend a few minutes and make sure your fridge is operating at peak efficiency today!
