Good to know
Compact fridges are often put in warm spots like garages or dorm closets. A hotter room makes any fridge work harder than the EPA test assumes.

Total cost context

Running cost is one part of what an appliance costs you. Purchase price, delivery, installation, repairs and how long it lasts are not included here, and we do not track prices. A model that is cheapest to run is not always the best value. Try the replacement calculator to see operating savings against your current appliance.
