Refrigeration Tips Once you have selected a new fridge or freezer, here are some additional energy efficiency tips you can follow: • Don't overfill the refrigerator - this blocks air circulation. • A full freezer will perform better than an empty one. • Clean your refrigerator's coils (in the back) and air intake grill (below the doors) every 3 months. • Allow hot foods to cool before putting them in the refrigerator. • Keep refrigerators and freezers out of direct sunlight, and allow at least 5 cm all around the unit.
