I've read that frost free freezers are a particular pain if they are stored in cold places like garages. We have a combined frost free fridge/freezer in our kitchen and the fridge part always accumulates ice on parts of the back panels, especially behind the salad cabinets, and we often end up with frosted lettuce & other veg. . On the other hand, our 30+ year old upright freezer in our garage has never given a moment's problems and as it's usually kept full only needs defrosting every 3 years. If you can still get the old type I'd get one . Newer technology is not always necessarily better. I think the problem is when you combine fridge and freezer, usually for space reasons. If I had the space I'd have separate appliances and opt for the old fashioned defrostable ones as they're more reliable.
