Wife bought a cheap GE chest freezer at a Home Depot 20 years or so ago. Lived in the garage in southern Nevada for 16 years. Think lotsa heat.
Still working today in the Kansas basement.
I was an appliance repair guy. The refrigerants are the problem. The kept changing them from R-12 up to R-1234 or whatever. R-12 running freezers and fridges, you could put a new compressor in them after there was a failure, and get another 30 years out of them. DESTROYING THE OZONE my ass. R-12 was so heavy of a gas that it would setting on the lowest part of the shop. You could practically sweep it into a dust pan. The AC in your cars, lasted longer and everything else. The new units, are better looking, but if they operated on older refrigerants, they would be more dependable. Now, you may as well buy a new one, if your 2 year old dies. Renting an appliance for a few months, will cost you about 12% of the cost of a new.
