Appliances account for as much as 13 percent of your electric bill and the refrigerator is probably using most of it. While most appliances can be turned on and off, you’re forced to leave your fridge running 24 hours a day. The cost of running this essential appliance can really add up over the year. However, there are a few things you can do to help keep those refrigeration costs down.

Get rid of the second fridge. If you have a second refrigerator or freezer in your garage or utility room, it might be time to kick it to the curb. These appliances, especially older models, could be tacking on an extra $100 a year to your electric bill.

Test your seals. The seals on your fridge keep in all that cold air. If they aren’t tight enough, air could leak through, causing the unit to cycle more often and increasing your energy costs. Check to see that your seals are tight by closing a sheet of paper in the door. If it slides out easily, you may want to replace the seals.

Clean the condenser coils at least once a year. Unplug your refrigerator, or turn off the breaker, so that there’s no power connection. Then vacuum the coils to remove any dust or dirt.

Use the energy-saving setting. Many refrigerators have an energy-saving mode. If yours does, turn it on to help keep your energy costs down.

Set the right temperature. Use a thermometer to set the inside temperatures. The fridge should be set at 36-38 degrees, while the freezer should be 0-5 degrees.

Place your fridge in the right place. If you have the option to relocate your refrigerator, make sure it’s away from heat sources. The heat from the oven, dishwasher or a sunny area could increase the expense of running your refrigerator.
