> When it’s freezing cold outside, it seems crazy that I warm the air of my house and then use electricity to keep the fridge cooler Installing ducts, etc. might take more energy than is consumed over the product life-cycle. It would add other limitations, such as only being able to put fridges next to exterior wall. Or most likely it'll add additional installation cost. Money perhaps better spent insulating your house better. You'd have fewer compatible vendors to choose from. Less competition. Flexibility is probably way more important than micro optimizations.
