Fridge energy use tips

Book a Repair

Your refrigerator is one of the hardest-working appliances in your home, running constantly to keep your food safe and fresh. But that tireless work ethic comes at a cost – refrigerators account for a significant portion of your home’s energy use. Fortunately, a few simple steps can drastically improve your fridge’s energy efficiency, saving you money and reducing your environmental impact.

Understanding Fridge Energy Consumption

Refrigerators work by removing heat from the interior compartments and releasing it to the outside. This process requires a compressor and refrigerant, which consume electricity. The amount of energy a refrigerator needs depends on several key factors.

  • Size: Larger refrigerators require more energy to cool.
  • Age: Older refrigerators are generally less efficient than newer models.
  • Temperature settings: Colder temperatures demand more energy.
  • Door seals: Faulty seals cause cold air leakage, forcing the fridge to work harder.
  • Location: Placing your fridge near heat sources makes it work harder.
  • Usage habits: Frequent door openings and overfilling increase energy use.

The most accurate way to gauge a fridge’s energy efficiency in South Africa is to consult its South African Energy Efficiency Label. This label provides an estimate of the appliance’s annual energy consumption (in kWh/annum) and helps you compare different models. Look for fridges with higher “A” class ratings (A+, A++, A+++) for greater energy savings.

Proper Temperature Settings

  • Refrigerator: Set the temperature between 35°F and 38°F (1.6°C and 3.3°C).
  • Freezer: 0°F (-17°C) is the ideal freezer temperature.

Organizing Fridge Contents for Efficiency

  • Group similar items: This minimizes the time you spend searching, reducing how long the door is open.
  • Space for airflow: Avoid overly-packed shelves which restrict air circulation and make cooling difficult.


Regular Maintenance and Cleaning

  • Clean condenser coils: Use a brush or vacuum to remove dust buildup at least twice a year. This dramatically improves efficiency.
  • Clean interior: Regularly wipe down shelves and remove spills to prevent mold and unpleasant odors.

Checking Door Seals

  • The dollar bill test: Close a dollar bill in the door. If it slides out easily, your seals need replacement.

Utilizing Energy-Saving Features

  • Vacation mode: This setting helps save energy when you’ll be away for an extended period.
  • Ice makers: Turn off the automatic ice maker if you don’t use it frequently.

Energy-Efficient Models and Features

  • Look for Energy Star (or similar): These models meet specific energy efficiency levels.
  • Top-freezer models: Generally more efficient than side-by-side models.
  • Variable-speed compressors: Adjust performance according to cooling needs.

Some smart fridges integrate with smart home systems, allowing you to:

  • Remotely monitor temperature: Get alerts if the temperature rises unexpectedly.
  • Receive maintenance reminders
  • Track energy usage
