A refrigerator is one of the most essential—and energy-hungry—appliances in any home. It runs 24/7, which means even small inefficiencies can add up over time. Fortunately, there are simple, practical steps homeowners can take to improve fridge efficiency, lower energy bills, and extend the appliance’s lifespan.

1. Set the Correct Temperature

Your refrigerator should be set between 35°F and 38°F, and the freezer at 0°F. Temperatures outside this range force the compressor to work harder than necessary, using more energy and potentially shortening the appliance’s life.

2. Keep the Coils Clean

Dust and debris on the condenser coils can significantly reduce efficiency. These coils are often located at the back or beneath the unit. Cleaning them twice a year with a vacuum or coil brush can help your fridge run more smoothly and consume less energy.

3. Check Door Seals

A faulty gasket (the rubber seal around the door) allows cold air to escape and warm air to enter, leading to unnecessary cooling cycles. Test the seal by closing the door on a dollar bill—if it slips out easily, the gasket likely needs replacement.

4. Allow Air Circulation Inside

Overfilling the fridge can block air vents and reduce airflow, causing uneven cooling and higher energy use. On the other hand, too few items can reduce thermal mass. Aim for a well-organized, moderately stocked fridge to maintain consistent temperatures efficiently.

5. Defrost Regularly (for Manual Units)

If your refrigerator doesn’t have an automatic defrost function, built-up frost can strain the system. Whenever ice buildup exceeds 1/4 inch, its time to defrost it.

6. Keep It Away from Heat Sources

Placing the fridge near ovens, dishwashers, or direct sunlight makes it work harder to maintain its internal temperature. If possible, relocate the unit or add insulation to minimize heat exposure.

7. Let Hot Food Cool Before Storing

Placing hot leftovers directly into the fridge raises the internal temperature, triggering the compressor to work overtime. Allow hot food to cool slightly before storing, while still following food safety guidelines.

8. Replace an Aging Model

Refrigerators older than 10–15 years may lack modern energy-efficient technology. Upgrading to an ENERGY STAR® certified model can result in significant long-term savings.

Final Thoughts

A few simple maintenance tasks and good habits can go a long way in making your refrigerator more energy efficient. These changes not only benefit your utility bills but also help your appliance operate reliably for years to come. A well-maintained fridge is a quiet contributor to a more energy-conscious home.
