Southern Ontario Canada. Attached garage, drywalled but not
heated/cooled. Can go slightly below freezing during winter and reach
towards 30C in summer.

Haven't decided about buying a Stand-up or a Chest freezer, but will be
larger in size like 15 cu foot or so. Best place for our family to keep
it is in the garage but does anyone have any experiences with a newer
Energy star rated freezer kept in conditions similar to mine? reliable?
Did it shut down in winter, did the compressor overheat in summer? was
the manufacturer's operating temperatures claims near accurate

Any difference in chest freezer versus stand-up in a garage environment?

Anyone got any input, it'd be appreciated....
