Start by unplugging that older extra refrigerator in the garage or basement. Older-model refrigerators cost an average of $150 per year to run. For the one in your kitchen, be sure it’s in a cool place with plenty of air circulation behind it, away from direct sunlight and heat-generating appliances that can make it work harder. Keep it set no colder than 35 to 38 F, and make sure the door seals fit tightly. Don’t stand with the door open either; grab what you need quickly. Keep the fridge as full as possible to help it hold a more consistent temperature. Allow hot foods to cool to room temperature before storing.
- Skill level: Basic
- Almost everything that can keep your refrigerator running as cost-efficiently as possible can be done in minutes.
- Cost range: $10 coil brush
- Keeping your refrigerator properly maintained only requires a coil-cleaning brush (if you have an older model fridge with exposed rear coils), available at most hardware stores, and checking and replacing door seals if they’re not airtight.
- Savings: Varies
- Keeping your fridge running efficiently not only saves energy, but can also increase its life span.
