Regular maintenance of household appliances can significantly reduce energy consumption. According to the U.S. Department of Energy, cleaning refrigerator coils annually can improve efficiency by up to 30%. Similarly, replacing HVAC filters every three months can lower energy use by 5% to 15%.
Energy Star, a government-backed program, reports that using a programmable thermostat can save about $180 per year on heating and cooling costs. Additionally, running dishwashers and washing machines with full loads and using cold water settings can cut energy usage by up to 50% per cycle.
For dryers, cleaning the lint filter after each load reduces drying time and energy consumption. The Department of Energy also recommends air-drying clothes when possible to save even more. These simple steps, verified by official sources, can lead to substantial savings over time.
