AEG's fridge freezers here are all fully integrated. Each is built into a tall housing behind a cupboard door that matches your kitchen, with the fridge above the freezer. They come from AEG's 3000, 6000 and 7000 series, and the same models are also listed under AEG built-in fridge freezers.

The first choice is how the freezer defrosts. Most models are Frost Free, so both compartments defrost automatically and you never need to chip away ice. Low Frost models also defrost the fridge automatically. Their freezer builds up ice more slowly than a conventional one, but it still needs defrosting now and then. The 3000 series model is a conventional AEG built-in non frost free fridge freezer with a manual-defrost freezer.

Next comes the storage split. Most models give 70/30, with roughly 180 to 207 litres of fridge space, which suits households that mostly buy fresh food. One model splits 60/40. If you freeze in bulk, AEG 50/50 fridge freezers offer 88 or 104 litres of freezer space. Nearly all models use a sliding hinge, where the cupboard door is fitted on rails and moves alongside the appliance door. One uses a fixed hinge, where the two doors are joined and open as one. Energy ratings run from C to E, and most models run at 34 or 35 dB.

To narrow the choice, check which hinge type your housing and cupboard door need. Then weigh Frost Free convenience against the larger freezer space of the Low Frost and 50/50 models. For fridges, freezers and freestanding models too, browse AEG refrigeration.
