Fridge-freezers are more ergonomic as the fridge, which is used most often, is at eye level. In addition, the fridge-freezers have a wide variety of models in width 60cm & 70cm and can be placed more easily in a small kitchen.
How can I improve the performance of my refrigerator?
Do not overload the fridge, leave enough room for air flow, clean the door seals, and make sure the temperature is set correctly (about 4°C in the fridge and -18°C in the freezer).
