New freezer -- Energy Star vs. manual defrost?
I'm freezer shopping for a smallish upright to replace my tiny chest freezer. In general, it seems the ones under 14 cubic feet are not apt to be Energy Star rated. Now, I'm skeptical about those ratings to begin with. And I do not mind defrosting my freezer manually. Does anyone know, energy-wise, how a small manual defrost would compare to an Energy Star rated auto-defrost? I guess what I'm asking is, doesn't that defrost process run the electric bill up, in and of itself? The freezer will go in the garage which does get pretty warm in summer. I have my eye on a 14.1 Frigidaire model (LFFU1424DW) that is exclusive to Lowes, because it will fit my space nicely.
Thanks for any thoughts or guidance.
